Title: Device for controlling capacity of refrigerant compressor
Inventor: OGATA YASUHIRO
IPC: F04B49/10
Filed: 1983-05-13
Abstract: PURPOSE:To improve reliability and facilitate disassembly, assembly, transportation, etc. by providing a gas path hole in a cylinder cover and mounting a three- way electromagnetic valve directly on the cylinder cover to enable piping operations to be abolished. CONSTITUTION:When a coil of a three-way electromagnetic valve 11 is not excited, an intake chamber 1a and the interior 5a of a bypass valve body 5 are uniformly pressurized through an exhaust path 11b of said valve 11 and an exhaust hole 13b of a cylinder cover 13 so that the bypass valve body 5 is lifted by a spring pressure of a compression spring 6. Thus, paths of the cylinder cover 13 and the bypass valve body 5 are opened so that high pressure gas produced in two cylinder portions and exhausted from a valve assembly 3 passes through the opened paths and is bypassed to the intake chamber 1a. Thus, by providing the gas path holes in the cylinder cover 13 and mounting said valve 11 on same is dispensed with piping operation, reliability improved and assembly, disassembly and transportation operations facilitated.

Abstract: PURPOSE:To promote temperature fall of working fluid to realize quick return to normal conductive character by providing a constraining means which is installed on an engaging piston, deformed in response to that when the working fluid reaches a second temperature lower than a first temperature which constrains returning action produced on the engaging piston, following release of receiving pressure. CONSTITUTION:When working fluid in a hydraulic pump 3 rises in temperature and reaches to a first temperature, an energizing means 70 is deformed in responding thereto, a control spool 7 in a first oil chamber 5 formed to a casing moves, generated oil pressure of the hydraulic pump is induced into a second oil chamber 6 formed to the casing as well, an engaging piston 8 in the second oil chamber is slided by reception of this oil pressure to engage with a part of a rotor, relative rotation between the rotor and the casing is suppressed, and the transmission of driving force between both is ensured, while the temperature fall of the working fluid is promoted. When the temperature of the working fluid becomes lower than a second temperature by this promotion of temperature fall, the engaging piston is returned with release of deformation by a constraining means 9, and transmission of driving force is resumed.

Title: Magnetic core for choke coil
Inventor: YOSHIZAWA KATSUTO
IPC: H01F27/24
Filed: 1983-05-16
Abstract: PURPOSE:To improve the high frequency characteristics and DC superposition characteristics and reduce the man-hour of winding and other processes by a method wherein a partial gap is provided to a junction surface of a combined core made of a superrapid-cooled thin strip. CONSTITUTION:A core is composed of laminated thin films obtained by slitting, punching or photoething or a toroidal winding of a thin film. A gap is formed at a part oaf a junction surface by making a step by flat plishing, making a groove by a slicer or the like. An amorphous thin strip is preferrable because it has higher saturatd flux density than ferrite and can improve the high frequency characteristics further. Especially in the aspect of DC superoposition characteristics, when a super-chilled silicon-steel thin strip, a sendust thin strip or an amorphous thin is used, the high high-frequency permeability is obtained. A Co-base small magnetostriction amrophous thin strip is more desirable because the deterioration of the characteristics due to the impregnation, the lamination and the like is small and high permeability is obtained and the inductance at the low current is increased.
