An end of a signal terminal of the flexible circuit board is electrically connected to a signal electrode of the optical modulating device. An end of a ground terminal of the flexible circuit board is electrically connected to a ground electrode of the optical modulating device. The other end of the signal terminal is soldered to the signal electrode pad of the driver, and the other end of the ground terminal is soldered to the ground electrode pad of the driver. | 2014-05-01 |
20140119746 | INTEGRATED CIRCUITS IN OPTICAL RECEIVERS - A circuit may include a photodiode configured to receive an optical signal and convert the optical signal to a current signal. The circuit may also include a transimpedance amplifier coupled to the photodiode and configured to convert the current signal to a voltage signal. The circuit may also include an equalizer coupled to the transimpedance amplifier and configured to equalize the voltage signal to at least partially compensate for a loss of a high frequency component of the optical signal. The equalizer and the transimpedance amplifier may be housed within a single integrated circuit. | 2014-05-01 |
20140119747 | IMAGE FORMING APPARATUS AND CONTROL METHOD THEREFOR - According to one embodiment, an image forming apparatus includes: a toner cartridge which includes a storage section; a toner motor; a toner-motor driving section; a count measuring section configured to measure a driving time of the toner motor and calculate a consumption count value of the toner; an event detecting section configured to detect operation events; a main body counter configured to sequentially update a main body counter value with the consumption count value and stores the main body counter value; a toner counter configured to store a toner counter value in the storage section; a counter comparing section configured to perform counter comparison of the main body counter value and the toner counter value; and an event processing section configured to perform processing for keeping consistency of the main body counter value and the toner counter value on the basis of the counter comparison. | 2014-05-01 |
20140119748 | TONER-FIXING DRUM CONTAINING HEATING LIQUID - A toner fixing system for fixing toner onto a receiver medium includes rotatable fixing drum partially filled by a heating liquid, so that a stationary-drum liquid level is defined. The heating liquid is warmed above a toner glass transition temperature. The fixing drum rotates fast enough to draw the heating liquid to substantially cover an inner surface thereof. The moving receiver medium contacts an outer surface of the fixing drum in a contact region above the stationary-drum liquid level. Heat is transferred through the rotating fixing drum from the drawn warmed heating liquid to heat the toner above its glass transition temperature. A sensor detects stoppage of the receiver medium in contact with the fixing drum. A controller automatically stops the rotation of the fixing drum when a stoppage is detected, so that the heating liquid is pulled by gravity away from the stopped receiver medium. | 2014-05-01 |
