Filed: 1989-09-01
Abstract: PURPOSE: To apply uniform light without any dark image portion to a scale by applying light obtained from a light emitting diode that is a lighting means to the scale through an optical fiber with a specific length. CONSTITUTION: A scale 10 is lit by a light emitting diode LED 22 that is mounted to a housing 24 and power is supplied to the LED 22 via a pair of lead wires 26 from a power supply. An optical fiber 30 with a specific length is mounted to the front of the LED 22 and is fixed by a member 32. The member 32 is connected to a housing 24 of the LED 22 by a proper method.

Title: Direct-coupled amplifier
Inventor: FUNAYAMA MITSUO
IPC: H03F3/347
Filed: 1989-08-31
Abstract: PURPOSE:To integrate a circuit and to reduce the cost by providing a DC detecting circuit, a voltage comparing circuit, and an amplifying circuit and constituting a feedback loop, and outputting an invariably constant bias current or voltage and a signal from the direct-coupled amplifier to the circuit of a trailing stage. CONSTITUTION:The collector current of a transistor(TR) 6 is higher when a demodulated signal of S-VHS is inputted to the amplifying circuit 3 than when a demodulated signal of normal VHS is inputted and the collector voltage drops by a voltage drop across a resistance 5. The demodulated signal of S-VHS which is outputted to a feed path 23, on the other hand, is inputted to the DC detecting circuit 2 and only a DC voltage is extracted from the demodulated signal. This DC voltage is applied to the inverted input terminal 3b of the voltage comparing circuit 3, which compares said DC voltage with a reference voltage Vb. Then such an output voltage that said DC voltage becomes as high as the reference voltage Vb is generated at an output terminal 3a. The decrease in the DC voltage Va of the feed path 24 is therefore controlled and the voltage is set constant.
