Abstract: PROBLEM TO BE SOLVED: To produce an optical circuit board capable of precisely connecting an optical circuit in a small space by composing the circuit board of a film base material having an adhesive layer, an optical fiber laid on the surface of the adhesive layer and a cover film to protect the optical fiber. SOLUTION: This circuit board consists of a film base material having an adhesive layer, an optical fiber laid on the surface of the adhesive layer, and a cover film to protect the optical fiber. The circuit board is produced by forming an adhesive layer on the film base material, laying the optical fiber on the surface of the adhesive layer, and providing a cover film thereon. As for the film base material, a material having flexibility and relatively good dimensional stability is preferable, and for example, a polyimide film and a polyethylene terephthalate film can be used. As for the cover film, the same polyimide film or polyethylene terephthalate film as that for the base film can be used.

Title: Signal switching device
Inventor: KURIYAMA KIYOSHI
IPC: H03K17/00
Filed: 1986-07-22
Abstract: PURPOSE:To reduce the number of coupling capacitors by setting an operation level almost to zero by the bipolar power source consisting of an external power source and an opposite-polarity voltage generating circuit. CONSTITUTION:A positive voltage VDD is applied to a signal switching device 43 from a positive single power source 26 through a power source input terminal 28. A negative voltage generated by a switched capacitor circuit 40 which is controlled with the oscillation period of an oscillation circuit 39 on the basis of this VDD is smoothed by a capacitor 42 connected to a terminal 41 to become a negative voltage Vss. This bipolar voltage source gives a zero potential as an operation point to other circuit systems included in the signal switching device 43 except a ternary ring counter 32, the switched capacitor circuit 40, and the oscillation circuit 39. Consequently, the signal of a signal source 1 is applied to the terminal 6 of the device 43 through a signal processing circuit 2 and a coupling capacitor 3 whose polarity is readily determined because one terminal is at (1/2)VCC and the other terminal is grounded, and the signal of a signal source 11 is applied to a terminal 16. Consequently, the number of coupling capacitors is reduced to facilitate high integration and also reduce a switching shock noise at the time of switch switching. &.

Filed: 1993-07-12
Abstract: PURPOSE:To easily confirm the normal transmission of stored originals in a memory by displaying an opposite side number inputted to the memory at the time of memory transmission and erasing the indication after the transmission is completed. CONSTITUTION:A control part 9 stores the opposite side number inputted from an operation part 6 and information concerning the transmitting state in a storage part 8 and displays the opposite side number on a display part 7. When the transmitting state is changed, the transmitting state information in the storage part 8 is reloaded, and the displayed information on the display part 6 is reloaded. When the transmission is normally finished, the opposite side number and the information data concerning the transmitting state corresponding to that number are erased. Therefore, an operator can recognize at a glance whether it is just under transmitting the originals which are stored in the memory and is not normally finished yet, or under waiting for redial, the opposite side does not respond to it or it is any transmission error or not. etc.
