Title: Optoelectronic integrated circuit
Inventor: SAWADA SOSAKU
IPC: H01S5/026
Filed: 1993-08-05
Abstract: PURPOSE:To provide a high sensitive photo-receiving or photo-transmitting and receiving optoelectronic integrated circuit by reducing the generation of dark current. CONSTITUTION:A low reflectance layer 11 comprising Ti and a bonding layer 12 comprising Au are successively lamination-formed on the rear surface of a semi-insulating substrate 10 comprising InP crystal. On the other hand, a pin-PD 20 and an HBT 30 are monolithically and integrally formed on the surface of the substrate 10. In such a constitution, light is emitted by light emitting recoupling in the base layer during the operation time of the latter 30 so as to emit the incident light to the former 20 in index-functionally attenuable mode while the photocomponent in wavelength sensitive to the PD 20 is absorbed into the layer 11 on the rear surface of the substrate 10 to be reflected thereon with the photointensity thereof reduced to fractions reaching the photoabsorbent layer for reducing the dark current so that the current corresponding to externally detected photo-amount may be generated.

Patent JP-H1127989-A (JP)
Title: Actuator control
Inventor: SAKURAI YOSHIHIKO
IPC: F24F13/10
Filed: 1997-07-04
Abstract: PROBLEM TO BE SOLVED: To obtain an optimum torque suitable for environmental conditions at that time by changing the drive signal from a high frequency to a low frequency, when the power source voltage is judged to be lower than the second set point and a drive load is judged to be large. SOLUTION: In addition to the selection of a drive torque by a power source voltage, a drive torque is selected based on the compartment temperature at the front side as one of the environmental conditions. By so doing, it becomes possible to carry out a finer actuator control. In particular, the range from V7 to V11, normally set to a high frequency mode can be set to low frequency when an increase in the drive torque is required depending on the environmental conditions, so that the drive torque can be secured. Also conversely in an ordinary condition, setting to the high frequency mode is possible when the power source voltage is more than V7, so that the range of the high-frequency mode can be made larger, by which a drive torque high than nucled can be avoided and the frequency of having higher operating speeds can be increased.
