Filed: 1984-03-30
Abstract: PURPOSE:To make delay setting by software unnecessary to eliminate the overhead by using a channel control word where a dealy is set, and providing a microprocessor, which interprets this channel control word, and a programmable timer. CONSTITUTION:A central processing unit of a system issues once a start input/ output instruction accompanied with the channel control word, to which delay of a certain time can be set, and petches in said instruction through a channel bus interface 8 provided in a channel part 4 and holds it temporarily in a random access memory RAM10. Thereafter, a microprocessor 9 interprets this channel control word and executes required processings through an input/output bus interface 12 and an input/output bus 5, and the programmable timer is used to set delay of a designated time. Thus, delay setting by software is unnecessary because prescribed command training to a terminal equipment is performed.

A voltage difference between the gates 90, 91 and the fingers 56 fixed to a substrate reference voltage is lowered, and threshold voltages of the channels 72a, 72b are also lowered. Thus, this device can be applied generally as an AC or DC switching power MOSFET.

Title: Fault detector for antiskid brake control pump, and detection method
Inventor: OKA YOSHIHIRO
IPC: B60T17/22
Filed: 1992-02-17
Abstract: PURPOSE:To automatically detect the fault of a pump by providing a means, which judges whether the a motor is rotating continuously for a certain period of time or more or not, and a means, which judges that a pump is faulty in case that the revolution of the motor is larger than the revolution threshold at noload and that it is rotating for a certain period of time or more. CONSTITUTION:If the voltage is constant, it can be judged whether a pump is in onload condition or noload condition by investigating the revolution of a motor. It will do to make the revolution, which becomes the standard of judgment, that is, the threshold the value of the revolution between on-load condition and no-load condition. Even if the voltage deviates, the revolution of the motor increases or decreases proportionally between the on-load condition and no-load condition, so it will do to judge that the pump is in no-load condition, with the threshold of the revolution, wherein the deviation of this voltage is taken into consideration, as the threshold THRR of the no-load revolution, in case that the revolution is larger than this value. In case that the value of a timer T is not larger than 150, the brake is stepped lightly, so it is not the fault of the pump, and this processing is finished.

Inventor: SUZUKI HIROYUKI
IPC: B65G41/00
Filed: 1985-03-26
Abstract: PURPOSE:To enable a conveyor to be swivelled stably by configurating a device in such a way that the speed of a driving gear located beyond the stated radius of gyration is set to be proportional to the radius of gyration, and traveling motion within the stated radius of gyration is allowed to repeat swivelling and stopping at the time interval which is proportional to the corresponding radius in the conveyor which can be swivelled in a form of a fan as referred to the title.

Accordingly, crawlers located beyond the crawler 3-3 are allowed to travel at the speed from V0/20 to V0 in proportion to the distance from the center of swivelling, but crawlers 3-1 and 3-2 are allowed to repeat swivelling and stopping at the time interval which corresponds to the distance from the center of swivelling. This configuration enables the conveyor to be smoothly swivelled.

Title: Gas diffuser
Inventor: HAGIWARA HIROYUKI
IPC: B05B1/02
Filed: 1983-04-08
Abstract: PURPOSE:To maintain freely gas diffusibly gaps by winding a porous flexible coating film on the outside of a perforated pipe in tight contact therewith and supplying gas to the perforated pipe so that the gas is passed through the flexible coating or is diffused from the winding edge of the film. CONSTITUTION:The gas supplied through a gas supplying pipe 2 is admitted from a branch chamber 3 through an introducing chamber 7 into an ejecting port 8a and lifts a coating film 9 against the reduced pressure. The gas lifting the film 9 ascends on the side surface of the chamber 7 along the outside circumference thereof and when the gas arrives atop the chamber 7, the gas is diffused through diffusing holes 10 into the liquid. When the supply of the gas from the pipe 2 is stopped, the film 9 is brought into press contact with the outside surface of the chamber 7 by the reduced pressure in a gas diffusing tank 1 and the film 9 closes the port 8 and therefore the infiltration of the fine solid component contained in the liquid is prohibited and the clogging in the port 8 is eliminated.
