Title: Air amplifier
Inventor: SHIGA TATSUHIDE
IPC: F15B5/00
Filed: 1986-12-26
Abstract: PURPOSE:To obtain a large loop gain and also miniaturize the device in the caption using a vacuum nozzle whose nozzle back pressure is below the atmospheric pressure, so as to generate suction force instead of repulsive force exerted on a flapper by a nozzle jet. CONSTITUTION:A nozzle 3, which is arranged in facing to a flapper 1, is connected to the vacuum part 24 of a vacuum nozzle 22 whose nozzle back pressure is below the atmospheric pressure. In the back pressure chamber 30 of a pilot relay 10 which can amplify the nozzle back pressure Pn of negative pressure, a spring 31 is provided, and the first diaphragm 33 is energized to the side of an atmosphere chamber 32. Accordingly, as suction force can be generated instead of repulsive force which is due to a nozzle jet, a large loop gain can be obtained without exerting any ill influence on a forward gain, while the device can be miniaturized.

Title: System for detecting idle input line in spatial switch
Inventor: ISHITOBI KIMIHIRO
IPC: H04Q3/52
Filed: 1991-11-26
Abstract: PURPOSE:To detect an idle input line in a spatial switch with configuration of a small scale circuit by using a control signal for a selector group of input line changeover as an address, writing data to a storage circuit and discriminating an address at which no data are written as an idle input line. CONSTITUTION:After two selector circuits of an idle input line detection circuit are initialized, the one circuit receives a logic value, outputs it to a RAM of the detection circuit and the other circuit selects an input to an M input selector 71 and outputs it to a RAM. The M selector circuit 71 inputs an output of switching circuits 41-4M controlling input selector circuits 31-3M. Then a control circuit 72 selects outputs of the switching control circuit sequentially, and the resulting output is used for a logic value 1 to be written as the address of the RAM. Thus, after all of the control circuits 41-4M are finished, any address not written with a logic value 1 corresponds to an idle input line and the idle input line is detected with the configuration of a small scale circuit.
