Title: Controller for electromagnetic pump
Inventor: OKUBO ICHIRO
IPC: F23N1/00
Filed: 1986-09-18
Abstract: PURPOSE:To prevent abnormal combustion, by stopping energization of an electromagnetic pump when energization time of the pump exceeds a preset period of time, in a controller for a liquid fuel-supplying electromagnetic pump for a hot water supply device or the like. CONSTITUTION:When a control signal in the range of 1-5 V is supplied according to a load, a pulse width modulating circuit 3 generates driving pulses with a pulse width according to the control signal. The pulse width of the driving pulses is smaller than that of limiting pulses generated by a limiting pulse generating circuit. The driving pulses are supplied to a transistor 12 through a comparator 6, whereby an electromagnetic pump 13 is continuously energized to supply a fuel. When the width of the driving pulses becomes larger than that of the limiting pulses, the transistor 12 is supplied with the driving pulses having the same width as that of the limiting pulses, whereby the energization of the pump 13 is stopped. With this arrangement, excessive supply of the fuel is prevented, and abnormal combustion can be prevented.

Filed: 1982-12-16
Abstract: PURPOSE:To exactly prevent the leak of a grout to the ground's surface by providing an injection inner tube with a tip device having upper and lower packers expanding or recovering by the pressure of a fluid and a rubber sleeve expanding by the pressure of the grout. CONSTITUTION:A sleeve grout SG is injected between the hole wall of the ground and an outer tube 60, and an injection inner tube with a tip device D is inserted into the outer tube 60. The upper and lower packers 27 and 31 are expanded by the pressure of a fluid W to cause it to closely adhere to the inner surface of the outer tube 60, and a grout G is supplied and discharged from an outlet 42.

IPC: H04L12/40
Filed: 1989-08-28
Abstract: PURPOSE:To improve the transmission rate by comparing a sender address and its own station address in a frame and invalidating the frame when the in-frame sender address is in error. CONSTITUTION:A terminal equipment 111 outputs a frame in which a station having the terminal equipment 111 is described as a sender address.

IPC: H05G1/34
Filed: 1983-11-26
Abstract: PURPOSE:To stabilize a d.c. high-pressure output voltage which is applied from a rectifying means to an X-ray tube by preventing its overshoot by intermittently switching a highly pressure-resistant vacuum tube at high speed. CONSTITUTION:When an X-ray exposure signal (S1) is introduced to control means 7 and 8, the control means 7 and 8 intermittently open and close tetrodes 4 and 5 at high speed respectively. As the result, a d.c. high-pressure output voltage sent from a rectifying means 3 is intermittently switched by the tetrodes 4 and 5 before being applied to an X-ray tube 6 through chalk coils 19 and 20. The d.c. high-pressure output voltage is controlled and stabilized by switching the X-ray exposure signal (S1) at a certain frequency and a certain pulse width predetermined in accordance with the voltage and the current of the X-ray tube 6. When the tetrodes 4 and 5 are turned off, electromagnetic energy accumulated in the chalk coils 19 and 20 is supplied to the X-ray tube 6. Therefore it is possible to stabilize the voltage of the X-ray tube 6 over a wide range extending from a small current to a large current.
