Patent JP-H0387907-A (JP)
Title: Reference current source circuit containing lsi
Inventor: SUGAWARA MITSUTOSHI
IPC: G05F1/56
Filed: 1989-08-30
Abstract: PURPOSE:To obtain an output constant current having high accuracy and high temperature characteristic by setting a constant current having no temperature coefficient or a corrected constant current with trimming by means of an element contained in an LSI and furthermore trimming the variance of a time constant against the current absolute value or the built-in capacity. CONSTITUTION:A temperature characteristic compensating voltage trimming circuit 1 applies a constant current I1 to a constant voltage diode ZD, divides the constant voltage VZ into VSU, VBC and VBD with the voltage dividing resistances RU, r1, r2 and RD respectively, and selects one of these divided voltages via a VB selection switch SW to supply it to a common base B of npn transistors TR Q1 - Q3. The resistance voltage (VB - VBE) obtained by subtracting the base-emitter voltage VBE from the reference voltage VB is applied to the emitter resistances R1 - R3 respectively. Then the current I1 - I3 obtained by dividing those emitter resistances by each resistance value are outputted from the collectors of the TR Q1 - Q3 respectively. Thus an output constant current I0 which is selectively synthesized with grant of duplication via the current switches S1 - S3 is obtained through an output terminal T0. In such a constitution, an output current having high accuracy is obtained.

IPC: G02B6/44
Filed: 1992-08-26
Abstract: PURPOSE:To eliminate unequalness and to suppress large local light leakage even if the above cable is curved by providing a clearance between a bare plastic optical fiber and a resin which coats this bare fiber and has light diffusivity. CONSTITUTION:One piece of the bar plastic optical fiber consisting of a structure of a core 1 and a sheath 2 is circumferentially coated with a diffusion layer 4 coated with a translucent resin having the diffusivity at >=0.1mm thickness. There is the clearance 3 of >=10mum between the bare fiber and the diffusion layer 4 for directly coating the bare fiber at >=20% of the entire periphery of the bare fiber particularly when the diameter of the bare wire of the plastic optical fiber is as large as 1 to 5mm. The diffusion layer 4 consists of one or multiple layers and a thermoplastic silicone elastomer is preferably incorporated into a part or the whole of the diffusion layer 4. This plastic optical fiber cable makes light emission expression without the unequalness in the light emission from the flank and, therefore, the cable curves at a gentle curve like a freely curving rule even in the case of wiring. The elegant light emission is consequently possible.

Title: Analog-digital converter
Inventor: ISHIBE MANABU
IPC: H03M1/52
Filed: 1982-12-28
Abstract: PURPOSE:To attain A/D converting operation without being affected by fluctuation of an offset voltage by using a current source which flows a current proportional to a change in the offset voltage. CONSTITUTION:A sample switch 7 is closed and a current switch 8 is opened at the sampling period. When the sampling is started, an output of an integration circuit approaches a value -kV0. When the integrating period is started, the sample switch 7 is opened and the current switch 8 is closed, causing the current switch 8 to be closed and then the integration is started with a prescribed slope and the integration output rises linearly in the positive direction. On the other hand, a counter 11 starts counting clocks at the same time and the counting of the clock is finished when a comparator 12 detects the zero of an output of the integration circuit and the count number corresponds to a digital output. If fluctuation of the offset voltage occurs, the output of the integration circuit is changed as shown by a curve 32 or 33 during the sampling period and reaches a value -kV0' or -kV0''. On the other hand, the output of the integration circuit is zero at an integration time (t1-t0) by the integration from the current source 14 of a current value proportional to the offset voltage.
