Title: Image display device
Inventor: KAIMASU HIROYUKI
IPC: H04N5/445
Filed: 1990-03-16
Abstract: PURPOSE:To make it possible to accurately decide signature characters independently of the normal image screen of a background by mixing a normal video signal with the video signal of additional information, and when the additional information image is superposed, outputting a normal video signal whose contrast is reduced. CONSTITUTION:The pin 9 of a microcomputer IC1 is connected to the base of a switching transistor(TR) Q4, and when a video switching signal is turned to 'H', the TR Q4 is turned on. The pin 10 of a Y/C mixing IC2 DC-controls the contrast of a video signal outputted from the IC2. Thereby, the AC gain of the video signal is increased in accordance with the increment of a DC voltage impressed to the terminal. The DC voltage impressed to the pin 10 of the IC2 is divided also by a resistor R2 in addition to a resistor R1 and its application voltage is dropped as compared with the normal state. Thus, the contrast of the normal image is reduced on a CRT screen and signature characters or the like can easily be read out.

Title: Current control circuit in wire transmission line
Inventor: KISHI KENICHI
IPC: H04B3/00
Filed: 1983-04-18
Abstract: PURPOSE:To prevent crosstalk from being generated in other transmission lines by making a coupling transistor (TR) nonconductive when the TR is electrically conducted by a switching control circuit and a large current flows to a cable. CONSTITUTION:When a photocoupler 2 and a TR3 are turned on, terminals C, D are electrically conducted, a large current flows to the cable by a voltage induced transiently, a voltage is produced across a resistor R4 and a TR5 is turned on. Thus, a current (i) flowing from the coupler 2 is by-passed and flows directly to the terminal D, and no current flows to the base of the TR3. Thus, the TR3 is turned off, the terminals C, D are made nonconductive and no large current flows. Since no current flows to the resistor R4 owing to the turning-off of the TR3, a base-emitter voltage of the TR5 becomes zero again, the TR5 is turned off and the TR3 is turned on conversely. A large current more than a prescribed value does not flow by repeating such operations.

Title: Channel management system in integrated service communication network
Inventor: NISHINO TETSUO
IPC: H04M3/42
Filed: 1989-03-20
Abstract: PURPOSE:To avoid inconvenience where other tenants cannot use channels entirely because one tenant occupies all channels of an interface by accepting an incoming call when the relation of maximum channel number > operating channel number is detected in a tenant detected by a channel registration management means from a subscriber number informed from a caller terminal equipment and rejecting the incoming call when the relation does not exist in the case of the arrival of call to an extension terminal equipment. CONSTITUTION:A call setting message(MSN) is sent from a caller terminal equipment to an ISDN station 16 and the ISDN station 16 sends the call setting message(MSN) to a PBX 10. Moreover, the ISDN station 16 sends a call setting acceptance to the caller terminal equipment and the PBX 10 applies the incoming call check. That is, a control section 14d searches the MSN of a tenant channel management table 15a with the MSN number noticed by the call setting message(MSN) and extracts the maximum channel number and the operation channel number having the coincident MSN. For example, when the operating channel number is smaller than the maximum channel number, the incoming call is accepted and the propriety of the incoming matching is judged, and when the result is good, the incoming call is accepted.
