Title: Constant current circuit
Inventor: MATSUMOTO KOICHI
IPC: H03F3/343
Filed: 1989-07-28
Abstract: PURPOSE:To suppress the error of a current value for a constant current circuit and to stably supply current by connecting base current from a pair of current mirrors in a PNP transistor, which constitutes the constant current circuit, through the collector/emitter current path of an NPN transistor to a negative power source. CONSTITUTION:A PNP transistor 4 generates a reference current corresponding to the resistance value of a resistor 6 and supplies a current, which is set to a suitable current ratio to this reference current, to PNP transistors T1-Tn. A PNP transistor 5 and an NPN transistor 7 constitute a pair of transistors for which inverted Darlington connection is executed. The base current of the current sources for the transistors 4 and T1-Tn are supplied. Accordingly, even when current amplification factor hEF of the PNP transistor is lowered in the process of manufacture, the current set to the prescribed current ratio can be stably supplied since the influence of the hEF to a collector current Ic4 of the above mentioned transistor 4 is reduced in comparison with the conventional constant current circuit.

Title: Distribution system for shared cryptography key
Inventor: KOBAYASHI TETSUJI
IPC: H04L9/08
Filed: 1986-08-22
Abstract: PURPOSE:To reduce the processing time required for the distribution of a cryptographic key by generating and erasing the cryptographic key and a decoding key of a discrete power function cryptographic device at each one distribution of a shared cryptographic key. CONSTITUTION:The shared cryptographic key, the key for encrypting the discrete power function cryptographic device 1, the decoding key, the key for a unidirectional function arithmetic unit cryptographic device 11, and a verification data or the like are generated by a random number generator in a processing unit 51. A couple of nodes use a value of modules (represented as N) used for the discrete power function cryptographic device 1 in common before the start of the delivery procedure of the shared cryptographic key and each node stores the value N into a storage device 52. Each node calculates a function G(N) defined by the explanation of the discrete power function cryptographic device together with the value N and stores the value G(N) in a storage discrete form. Thus, the processing time required for the key distribution in a communication equipment is decreased remarkably by the distribution system for the shared cryptographic key using the encryption method of the discrete power function.

Title: Electrophotographic printer
Inventor: YAMAMOTO SATOSHI
IPC: G03G21/00
Filed: 1989-07-31
Abstract: PURPOSE:To obtain an electrophotographic printer having high total throughput by setting a set temperature to a lowest temperature sufficient to allow a fixing unit to reach the lower limit of a temperature range after time necessary to convey a printing sheet to the unit is elapsed. CONSTITUTION:A fixing unit 12 is heated by a heater 13, and so controlled as to become a range of temperatures TM-TL, When the temperature of the unit during heating reaches a Tp, heating by the heater 13 is continued, possibility of start of printing is notified to a printer controller 11. If video data for one page is provided, a command of start of printing is rapidly output to start printing. However, the temperature of the unit 12 at the time of start of printing is lower than the temperature TL, and predetermined conveying time is required until a printing sheet is conveyed to reach the unit 12. The temperature of the unit 12 upon reaching is raised to a range capable of fixing. Accordingly, when the sheet reaches the unit, fixing is simultaneously conducted. Therefore, first printing time and recovery time after jam is released can be shortened, and total throughput of a printer can be improved.

IPC: H04N5/60
Filed: 1984-09-20
Abstract: PURPOSE:To prevent the sound blurring and distortion of a sub-signal caused by the excessive modulation, etc., of a main signal by removing a sub-signal carrier from the output signal of a differential amplifier and applying the remaining main signal component to the differential amplifier so as to remove it. CONSTITUTION:A sub-signal carrier for including a main signal component is inputted through a terminal 1 and applied to the base of a transistor (TR) 11 of a differential amplifier composed of TRs 11 and 13. Their outputs are passed through a level shift circuit composed of a TR 15 and diode 16, and one of them are applied to a TR 19 of the differential amplifier. When the signal applied to a resistance 17 is passes through an LPF constituted of the resistance 17 and a capacitor 28 and the sub-signal carrier is removed, a main signal component remains. It is applied to the TR 13 of the differential amplifier, made a direct current by an LPF constituted of a resistance 27 and capacitor 3, and further applied to the TR 11 of the differential amplifier as a bias voltage. Then the main signal component is applied to differential amplifiers 11 and 13 with synchronization, and its output whose main signal component is removed is outputted, thereby obtaining a stable sub-signal carrier as outputs of differential amplifiers 19 and 20.

Title: Optical module
Inventor: TOMIOKA TAZUKO
IPC: G02B6/122
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration of the element of an optical module from quickening and the yield from lowering even when it is flip chip-mounted, by forming an electrode pad on the position projecting by a prescribed amount from the outer surface position of an active area vicinity part of an optical device. SOLUTION: Flip chip bonding electrode pads 3-1, 3-2 exist in the vicinity of both sides of a stripe 2 being a light emission area of a light emitting element 5. These electrode pads 3-1, 3-2 are placed at a position higher by Δt (position projecting by Δt) than height h of a part containing the stripe 2 area (than the position of a surface of a hollow). When such a structure is adopted, even when the chip of the light emitting element 5 is flip chip-bonded on a sub-mount 6, the area containing the stripe 2 is parted from the surface of the sub-mount 6 at least by Δt or above. Thus, since the light emitting element 5 whose area containing the stripe 2 isn't stuck directly to the sub-mount 6, the probability that stress is applied to the stripe 2 is eliminated.
