20090215331 | BOAT PROPULSION SYSTEM, CONTROL DEVICE THEREOF, AND CONTROL METHOD - A boat propulsion system includes a power source, a propulsion unit, a propeller rotational speed detection section, a shift mechanism, an actuator, a control lever, a shift position detection section, an accelerator opening detection section, and a control unit. When the control lever is operated such that a shift position is changed from a first shift position to a second shift position, while the absolute value of accelerator opening varying speed becomes equal to or larger than a predetermined value, the control unit enables the actuator to maintain the first shift position until the rotational speed of a propeller becomes equal to or lower than a predetermined rotational speed and then to change to the second shift position. This minimizes a load generated on the power source, the power transmission mechanism, and other components of the boat propulsion system. | 08-27-2009 |
20090215335 | BOAT PROPULSION SYSTEM, AND CONTROL DEVICE AND CONTROL METHOD THEREFOR - An outboard motor includes a power source, a boat propulsion section, a shift position switching mechanism, a clutch actuator, and a control device. The shift position switching mechanism switches among a first shift position in which a first clutch is engaged and a second clutch is disengaged, a second shift position in which the first clutch is disengaged and the second clutch is engaged, and a neutral position in which both the first clutch and the second clutch are disengaged. When a gear shift is to be made from the first shift position to the second shift position, the control section causes the clutch actuator to gradually increase an engagement force of the second clutch. The outboard motor reduces the load to be applied to the power source and the power transmission mechanism at the time of a gear shift in a boat propulsion system including an electronically controlled shift mechanism. | 08-27-2009 |
20090215337 | BOAT PROPULSION SYSTEM, AND CONTROL DEVICE AND CONTROL METHOD THEREFOR - A boat propulsion system includes a power source, a propulsion section, a shift position switching mechanism arranged to switch among a first shift position, a second shift position, and a neutral position, a gear ratio switching mechanism, an actuator, and a control section. When switching is to be performed from the neutral position to the first shift position and the high-speed gear ratio, the control section is arranged to cause the actuator to, maintain the low-speed gear ratio, switch to the first shift position, and then establish the high-speed gear ratio when the current gear ratio of the gear ratio switching mechanism is the low-speed gear ratio, and cause the actuator to establish the low-speed gear ratio before switching to the first shift position, switch to the first shift position, and then establish the high-speed gear ratio when the current gear ratio of the gear ratio switching mechanism is the high-speed gear ratio. This arrangement improves the durability of a power source and a power transmission mechanism in a boat propulsion system including an electronically controlled shift mechanism. | 08-27-2009 |
20090269997 | BOAT PROPULSION SYSTEM, AND CONTROL DEVICE AND CONTROL METHOD FOR THE SAME - An outboard motor includes a prime mover, a marine propulsion unit having a propeller arranged to be driven by a rotational force of the prime mover to generate a thrust force, a shift position changing mechanism, a shift position changing mechanism actuator, and a control unit arranged to control the shift position changing mechanism actuator. When the shift position is changed to one of the first shift position and the second shift position from the neutral position, the control unit inhibits a change in the shift position to the other one of the first shift position and the second shift position until a predetermined time period elapses. The above arrangement improves the controllability of a boat propulsion system having an electronically controlled shift mechanism. | 10-29-2009 |

20080246400 | Gas Discharge Tube Light Source Apparatus and Liquid Chromatograph - The present invention relates to a gas discharge tube or the like having a structure for enabling the maintenance of discharge startability and the prevention of the shortening of the life of an anode section and for increasing the amount of visible light from a visible light source passing through a discharge path restricting section. The gas discharge tube comprises a sealed vessel in which gas is encapsulated. A cathode section and anode section for generating discharge are arranged in the sealed vessel. Furthermore, a discharge path restricting section for narrowing a discharge path is arranged between the cathode section and the anode section. In particular, an opening portion is formed in the anode section, and the cross section of the opening portion has a non-circular shape where the maximum opening width in a first direction is different from that in a second direction orthogonal to the first direction. Thus, the amount of the visible light passing through the opening portion of the anode section in the gas discharge tube from the visible light source can be increased by making the maximum opening width in one direction of the first and second directions longer than that in the other direction. The maintenance of the discharge startability and the prevention of the shortening of the life of the anode section can be attained by making the maximum opening width in the other direction shorter than that in one direction. | 10-09-2008 |
20100156263 | DEUTERIUM LAMP - The present invention relates to a deuterium lamp with a structure to enable high-accuracy positioning with respect to a mounting object such as an analyzer. The deuterium lamp comprises a sealed container in which a light-emitting portion to emit a discharge light in a predetermined direction is stored. The sealed container is constituted by a hollow body portion in which the light-emitting portion is stored and a hollow guide portion which guides a discharge light from the light-emitting portion to a light exit window provided at its front end. The deuterium lamp further comprises an axis adjusting member fixed to the hollow guide portion while storing at least a part of the hollow guide portion and a sealing layer for fixing the hollow guide portion and the axis adjusting member to each other. In particular, the sealing layer makes it possible to fix the axis adjusting member to the hollow guide portion with the center axis of the axis adjusting member being made coincident with the emitting direction of a discharge light. Thereby, even when misalignment has occurred between the center axis of the hollow guide portion and the emitting direction of a discharge light due to a manufacturing error in manufacturing of the container, since the axis adjusting member itself is directly fixed to the mounting object, it becomes possible to fix said deuterium lamp to an analyzer or the like with the optical axis aligned at a high accuracy. | 06-24-2010 |

20090186649 | COMMUNICATION TERMINAL AND MOBILE COMMUNICATION SYSTEM - A mobile communication terminal according to the present invention has a leaky transmission line whose radiation direction faces opposite a radiation direction of a part or a whole of the leaky transmission line of a wireless base station, as at least a part of an antenna element, connected to the communication terminal. Here, preferably, when a difference in angle between the radiation directions falls within the range between 180±7.5 degrees, the radiation directions are considered to face opposite each other. With this configuration, even when the leaky transmission line of the wireless base station has a curved line portion, a curved portion or the like, it is possible to ensure satisfactory communications with the wireless base station without a complicated configuration of the system but by a simple process to build the system. | 07-23-2009 |
