Title: Diaphragm pump
Inventor: NUMATA KAZUYUKI
IPC: F04B43/067
Filed: 1978-06-27
Abstract: PURPOSE:To attain an effective pump performance, by changing the position of a valve stopper, controlling the time of opening of a feed valve and regulating the effective volume swept by a piston to supply oil. CONSTITUTION:An oil pressure chamber 3 and a feed port 26 are connected to each other for the time from the starting of ascent of a piston 21 to the closing of the valve 27 after the separation of the valve stopper 30 from the upper end face 20a of a cylinder 20. The pressurization of the oil is started when the valve 27 is closed. The discharged quantity of the pump is usually determined by the volume swept in the pressurization travel after the closing of the valve 27 because the volume of the oil swept by a piston 21 is equal to that of paint through a diaphragm 1. The position of the valve stopper 30 can be changed to regulate the pressurization travel to alter the maximum discharged quantity. Therefore, the discharged quantity can be optimized as to various specified levels of pressure.

Filed: 1989-03-31
Abstract: PURPOSE:To measure only the temp. of a heated object to be detected by providing a cut-off circuit changing over a discharge lamp from a lighting state to a light-out state, and an optical system for guiding the radiation from the object to be detected to a photodetector at the time of light-out and receiving the signal from the photodetector to record a transient curve of radiation. CONSTITUTION:When the temp. of the electrode of a lamp 2a in a lighting state is measured, both of the radiation from the electrode and that from an arc are obtained in a photodetector 3 through a lens. The current flowing to the lamp is cut off from a state receiving both of infrared radiations by a cut-off circuit 1b to put out the lamp 2a. The radiation from the arc is attenuated as shown by a shaded part A to take out only the radiation from the electrode at the part of a curve B. At this time, since the arc is attenuated within a short time, only the radiation from the electrode can be measured on and after the point C at the end part of the shaded part A to obtain the curve B. As a result, since the cut-off lamp 2a is put out and the measuring curve as shown by a solid line b is obtained, radiation intensity at the time t0 of radiation intensity I0 before the cut-off time t0 of the current can be calculated by the estimation from the curve B.

Filed: 1995-04-04
Abstract: PURPOSE: To make it possible to control a reactive power generator for power systems by dividing a power system to calculate matching between a reactive power generating source and a reactive power consuming source within the power system. CONSTITUTION: Fed with data on a power system from a data reading device 102 through a communication line 258, a power system division calculating device 104 divides the power system into subsystems most suitable for voltage reactive power control. For each of the resultant subsystems, the amounts of reactive power consumed and generated are calculated, and the adequacy of reactive power balance is judged. As a result the system in question is dynamically divided into the subsystems, and reactive power is allotted with reactive power balance taken into account for each subsystem. This enables prevention of reverse control phenomena. This also makes it possible to perform total calculation at high speed and thus provide voltage reactive power control on- line.
