Patent JP-S63192118-A (JP)
Title: Switch input device
Inventor: ASAI TAKAHIRO
IPC: G06F3/02
Filed: 1987-02-04
Abstract: PURPOSE:To reduce a trouble for connections and wirings by changing each time constant of a pair of resistance groups against an optional switch input of a switch group to produce a specified signal at the switch input and detecting this specified signal by a microcomputer. CONSTITUTION:The time constants of a pair of resistance groups 4 and 5 change against an optional switch input of a switch group 1. Then a specific signal is produced at the switch input and detected by a microcomputer 3. In other words, plural switches 1a-1d are applied to one of both time constants of an astable multivibrator circuit 2 and simultaneously the other time constant is also controlled. Thus those switches can be quickly detected with no malfunction and furthermore the inputs of switches 1a-1d can be detected just with a single input terminal against the microcomputer 3. As a result, the trouble can be reduced for connections and wirings.

IPC: B01D53/22
Filed: 1985-02-08
Abstract: PURPOSE:To make it possible to use a waste water treatment method by vacuum evaporation even in a small scale factory, by charging waste water in an evaporation tank held under vacuum and having an oil layer in the bottom part thereof and allowing generated steam to pass through a steam permselective membrane. CONSTITUTION:The embodiment of chromium waste water is shown. At first, the chromic acid waste water discharged from a plating tank is charged in an evaporation tank 1 from above. The evaporation tank 1 is connected to a cushion tank 3 through a check valve 5 and the cushion tank 3 is held to a vacuum degree of 10-30mmHg by a vacuum pump 9 through the check valve 5 and a steam permselective membrane. Therefore, the evaporation tank 1 is also held to said vacuum degree. Because the layer of oil 11 is formed in the evaporation tank 1 in an amount sufficient to splashing charged waste water, said waste water is separated into water and sludge 13 to accumulate the sludge 13 to the lower layer of oil 11. Therefore, the vacuum evaporation treatment of waste water is enabled by a simple method.

Filed: 1989-02-02
Abstract: PURPOSE:To eliminate loss in switching elements and to prevent heating of the switching elements by sustaining the potential at neutral point approximately at an intermediate level, thereby detecting counter-electromotive force reliably. CONSTITUTION:Since digital signal wave F is fed to all gates 16, 17, 18, 19, 20, 21, pairs of switching elements Tr 1 and Tr 5, Tr 1 and Tr 6, or Tr 2 and Tr 6,..., at source side and ground side, which are turned ON when commutation is carried out are opened/closed simultaneously with high frequency. Consequently, potential at the neutral point Q of stator coils 11, 12, 13 connected in star is approximately held at a constant level which is half of source voltage Vcc. By such arrangement, square wave can be obtained accurately as a commutation signal through detection of counter-electromotive force, although high frequency digital signal wave F is employed.
