Title: Electrode of vacuum interrupter
Inventor: NODA TAIJI
IPC: H01H33/664
Filed: 1988-06-07
Abstract: PURPOSE:To obtain a contrate type electrode of a high durability by using a beryllium-copper alloy with a thermal expansibility larger than a composite metal to compose a contact at a magnetic field generator, and incorporating it with the contact by soldering. CONSTITUTION:A magnetic field generator 30 is formed of an alloy of beryllium and copper, while a contact 40 is formed of a composite metal made by fusing copper to a porous sintered body of at least two sorts of metallic powders with the melting point higher than copper, and setting its thermal expansibility less than that of the magnetic field generator 30. The beryllium-copper alloy improves the mechanical strength after a high temperature soldering, and has a higher thermal expansibility compared with the composite metal to compose the contact 40. By the difference of the thermal expansibility, the thermal stress is left at a cylinder 33 in which including grooves 34 are formed after the soldering. Consequently, the mechanical strength as an electrode is made same as or higher than that before the soldering.

Abstract: PURPOSE:To prevent the appearnce of a black frame when printing is performed by calculating the copying range of a copied image formed on a recording sheet on the basis of the size of the image and on the magnification of a projecting lens and regulating copying range other than the calculated copying range. CONSTITUTION:A shutter 8 is provided as a regulating means which controls whether image light from a microfilm F is projected and exposed on a photosensitive body drum 7 when a print mode is selected. The controlling means calculates the copying range of the copied image formed on the recording sheet on the basis of the size of the image and on the basis of the magnification of the projecting lens 5, and performs control which regulates copying the range other than the calculated copying range by means of the shutter 8. The shutter 8 receives the control and regulates forming a copied image which is in the outside of the copying range onto the recording sheet. Thus only an copied image which exists in the copying range is formed on the recording sheet, and the appearance of the black frame can be prevented.

Filed: 1984-07-06
Abstract: PURPOSE:To improve the quality by detecting an overcurrent flowed to an inverter and a bridge circuit by a photocoupler or the like circuit at the prescribed value to turn OFF a switching element, thereby preventing the element from damaging. CONSTITUTION:An inverter for pulse-width-modulating via power transistors 2- 7 is formed, and has a base controller 14 and a controller 15 for controlling to pulse-width-modulate it. The current flowed to the inverter is detected by current detecting resistor 17 and photocouplers 19, 20.

The signal of the base controller 14 is broken by the thyristor 27, and the transistors 2-7 are turned OFF. The irregularity of the gate sensitivity of the thyristor 27 is regulated by altering the resistance value of the resistor 23, and the operating point of the overcurrent protecting circuit is maintained constantly.

Title: Vacuum control valve
Inventor: SUZUKI KENJI
IPC: F02D35/00
Filed: 1984-07-04
Abstract: PURPOSE:To reduce an output vacuum over the entire load area of an engine, by using a vacuum control valve to reduce the output vacuum with a decrease in atmospheric pressure. CONSTITUTION:When pressure in an atmospheric chamber 19 is decreased, a second pressure plate 15 is lowered since vacuum in a second vacuum chamber 21 is constant. The force applied to the second pressure plate 15 is transmitted to a first pressure plate 5 to lower the same. Accordingly, if an engine load is constant, and vacuum introduced to a first vacuum chamber 9 is constant, the force for raising a first diaphragm 1 and the first pressure plate 5 due to the pressure differential between the first vacuum chamber 9 and a pressure regulating chamber 7 is reduced by the force for lowering the first pressure plate 5. Accordingly, to obtain the same output vacuum from an output port 4, the vacuum in the first vacuum chamber 9 must be increased by the amount corresponding to the reduction in the raising force of the first diaphragm 1 and the first pressure plate 5. That is to say, if the engine load is asme, the output vacuum is reduced over the entire load area.
