Title: Optical circuit
Inventor: YANDOO DOSINOBU
IPC: H01L33/00
Filed: 1985-12-06
Granted: 1990-06-20
Abstract: The optical circuit comprises a photosensor provided with a transistor having a bias element connected between the emitter and the collector. A light emitting element is connected in series to the transistor. A photosensitive element receives light emitted by the light emitting element and transforms it into electric current, with one end connected with the transistor. Since only two interface lines are needed, one being the line for feeding the transistor with electric power and the other being the line of taking out the output of the photo sensitive element, the number of interface lines is reduced and thus the realisation is simplified.

Abstract: The  circuit  transmits  the  bidirectional  impulse  signal generated at falling and rising edges  of  the  serial  data.  The transmitted signal is detected by hysterisis characteristic  of  a comparator. When transmitting the data at a latch (IC1) of a  main transmitter (100), the DC voltage is cut off by  a  resistor  (R1) and capacitor (C1) to provide the impulse voltage transiently at a first transformer (T1) whose  secondary  node  (D)  generates  the reverse emf sending to  a  second  transformer  (T'11)  of  a  sub keyphone. The received signal  is  compared  at  on  OP  amplifier (IC'4) operating as a comparator with its voltage hysterisis.  The output of the OP amplifier is provided to a microprocessor (10) by adjusting the voltage with resistors (R'14-15).

Abstract: The resin composition is made of epoxy resin, hardening agent, hardening promoter, stress relaxation agent, and modified maleimide epoxy resin(I) as a heat resistance agent, which is included by 0.1-30 wt% to the whole resin composition. The addition of modified imide epoxy resin makes the resin composition more heat-proof and transformable for packing semiconductor devices.
