20090193180 | SEMICONDUCTOR MEMORY DEVICE AND CONTROL METHOD FOR SEMICONDUCTOR MEMORY DEVICE - A memory card capable of connecting to a host device includes a flash memory, a host interface unit which transfers data between a host device and the memory card, and a transfer mode control unit which changes a data transfer mode based on a command from the host device. The transfer mode control unit outputs status data containing an error code to the host device if a transfer mode change command is inputted from the host device, instructing the memory card to change to a transfer mode not supported by the host interface unit of the memory card. | 07-30-2009 |
20090217111 | EVALUATION METHOD AND EVALUATION SYSTEM FOR SEMICONDUCTOR STORAGE DEVICE - An evaluation method is proposed to evaluate reliability of a nonvolatile memory in a semiconductor storage device with respect to data writing and data reading. While power is being supplied to the semiconductor storage device, a test program and the control program are written in a storage unit of the semiconductor storage device. The test program being written to control execution of an evaluation test performed for evaluating the reliability of the nonvolatile memory and generate a simulated access command identical to an access command input externally for accessing the nonvolatile memory. Access to the nonvolatile memory is controlled according to the test program and control program in the storage unit. | 08-27-2009 |

20110284431 | PIEZOELECTRIC VALVE AND OPTICAL GRANULAR MATERIAL-SORTING APPARATUS UTILIZING SUCH PIEZOELECTRIC VALVE - A piezoelectric valve comprising: a valve main body formed in which are a gas pressure chamber that takes in compressed gas supplied from the outside as well as a gas release channel through which the compressed gas is released from the gas pressure chamber; a valve body placed in the gas pressure chamber to open and close the gas release channel; a piezoelectric element that generates, in the form of displacement, a driving force needed to operate the valve body; at least one displacement amplification mechanism that amplifies a displacement of the piezoelectric element and causes it to act upon the valve body; and a driving means for applying voltage to the piezoelectric element in order to drive the valve body to open the valve and thereby open the gas release channel; wherein such piezoelectric valve is characterized in that the driving means applies voltage to the piezoelectric element in multiple stages so as to suppress fluctuation in the amount of gas ejected from the gas release channel when the valve opens. | 11-24-2011 |
20120124314 | RECORDING MEDIUM - A recording medium according to an embodiment includes: a storing section including a first area in which a number-of-reproductions limited file is written and a second area in which at least one determination address in an address range of the first area, in which the number-of-reproductions limited file is written, and a number of readable times of the number-of-reproductions limited file are written; and a control section configured not to perform, after the number of readouts of reading out of data in the at least one determination address reaches the number of readable times, output of the number-of-reproductions limited file in response to a readout request for the number-of-reproductions limited file. | 05-17-2012 |
20130256200 | OPTICAL GRANULAR MATERIAL-SORTING APPARATUS UTILIZING PIEZOELECTRIC VALVE - An optical granular material-sorting apparatus includes: a transfer means for transferring objects being sorted; an optical detection means for detecting, at a detection position, objects being sorted as they drop from an end of the transfer means; and a blasting means provided below the optical detection means and designed to blow away objects being sorted through blasting of air based on the result of detection by the optical detection means. The blasting means has a piezoelectric valve which is driven by a driving means to blast air based on the result of detection by the optical detection means. The driving means applies voltage to a piezoelectric element in multiple stages so as to suppress fluctuation in the amount of gas ejected from a gas release channel when the valve opens. | 10-03-2013 |
20140061103 | OPTICAL SORTING MACHINE - The present invention intends to provide an optical sorting machine which can improve the collection rate of non-defective products without increasing the size of the machine. The optical sorting machine of the present invention includes a granular object feed unit including storage means that stores an object to be sorted, and transfer means that transfers the object to be sorted from the storage means; an optical sorting unit including optical detection means that detects an object to be sorted falling along a predetermined trajectory from an end portion of the transfer means, determination means that determines a type of the object to be sorted based on a detection signal from the optical detection means, an ejector that removes an object to be sorted determined as a specific type from the predetermined falling trajectory based on a determination result by the determination means, and a discharge hopper having a first discharge passage provided at a falling position of the object to be sorted falling along the predetermined trajectory, a second discharge passage provided at a falling position of the object to be sorted removed from the predetermined falling trajectory, and a third discharge passage formed between the first discharge passage and the second discharge passage; and conveyance means that conveys an object to be sorted discharged from the third discharge passage of the discharge hopper in the optical sorting unit to the storage means of the granular object feed unit. | 03-06-2014 |
20140166549 | CHUTE FOR OPTICAL SORTING MACHINE - A chute for an optical sorter sorting machine allows objects to be sorted to drop under gravity from the lower end of the chute, thereby supplying the objects to an optical detection section. The chute is provided with: a first portion which includes a portion for receiving the objects to be sorted which are supplied from a supply section; and a second portion which continues from the first portion The first portion is composed of a single part and has: flat surfaces along which the objects to be sorted flow down; and connection surfaces. The flat surfaces located upstream are bent downward, and the connection surfaces located downstream are is bent upward to form a smooth undulation in the surface along which the objects to be sorted flow down. | 06-19-2014 |
