Patent JP-S5817654-A (JP)
Title: Semiconductor device
Inventor: HIRASHIMA KENJI
IPC: H01L21/331
Filed: 1981-07-24
Abstract: PURPOSE:To form a Darlington-transistor for high speed in one semiconductor substrate by preventing the formation of a resistor between the emitter electrode of a transistor at the output side and a base just under an emitter and obviating the formation of a junction diode between the emitter electrode and a collector. CONSTITUTION:The formation of the resistor is prevented between the emitter electrode E of the transistor Q2 at the output side and the base 2 just under the emitter by shaping no P type through section under the emitter electrode while the formation of the junction diode is obviated between the emitter electrode and the collector 1. The transistor Q2 only functions as a diode. A drawing diode D1 is needed in order to realize the Darlington-transistor for high speed. According to this invention, the diode D1 can be incorporated into the substrate of the transistor in monolithic form, the change of the diode D1 into a transistor is avoided, and an assembling process can be simplified by shaping the diode into a single chip.

Title: Optical fiber
Inventor: SATOU HISASHIGE
IPC: G02B6/44
Filed: 1982-07-02
Abstract: PURPOSE:To suppress the generation of deviation in phases by providing a colored quartz glass layer on the outside circumference of an optical fiber consisting of a core part and a clad part enclosing the same. CONSTITUTION:The light (a) which is transmitted through the inside of a core part 1 transmits the inside of a clad 2. The light (b) thereof is reflected by the boundary face 5 with a quartz glass protective pipe 4, and the light (c) thereof enters the inside of the core 1 again to give a rise in the deviation of phases, but if the tube 4 is colored to, for example, black, the light (b) passed the inside of the clad 2 is absorbed. The light (b) emitted once to the outside of the system does not return again to the core part 1, and since the phase of the light inputted initially is maintained as it is, the reliability is improved with respect to the signal of the light outputted and such information which requires delicate control is effectively transmitted.

Title: Digital video signal multiplex transmission method and device therefor
Inventor: TANABE KAZUHIRO
IPC: H04N7/081
Filed: 1994-05-27
Abstract: PURPOSE:To eliminate noise and distortion by generating a transmission signal in which a signal period and a non-signal period are repeated, sending the transmission signal corresponding to the signal period from a camera and sending a signal from a CCU for the non-signal period. CONSTITUTION:A transmission synchronizing code and a frame signal coded once per one frame are inserted to a head of transmission data of a camera controller CCU 18. A camera 1 detects a frame signal by using a video phase detector 8, a reference video image phase generating circuit 9 generates a reference video phase signal based on the phase to control the input/output of the camera 1. After the synchronizing code is detected, a transmission signal data of the CCU 8 are received for a period T0 and after the data are received, a reception gate 19 is closed and an output gate 20 is get through to send the transmission signal data of the camera 1 for a period T1 to a cable 10. Thus, two-way transmission between the camera 1 and the CCU 18 is attained and a frame signal as video phase information is easily sent.
