Abstract: PURPOSE:To reduce magnetic reluctance in a magnetic circuit and allow magnetic flux to be more efficiently concentrated into a moving-core by providing a yoke made of magnetic materials forming an extension part of a pressure tube, the moving-core inserted slidably in the axial direction inside the pressure tube and the extension thereof. etc. CONSTITUTION:A coil 4 is wound on a coil case 3 to form a solenoid coil. The coil case 3, a yoke 10, a fixed core 9, and a moving-core 1 made of soft magnetic materials respectively are disposed to reduce magnetic reluctance in a magnetic circuit surrounding the coil 4 in order to operate magnetomotive force to the moving-core 1 effectively. A pressure tube 2 is made of non-magnetic materials. The pressure tube and the yoke are enabled to be fitted close in fluid to one end of the fixed core 9 with an O-ring 25 and to the other end of the pressure tube 2 with an O-ring 26 respectively. One part of the yoke 10 in the thicknesswise direction is used as a magnetic path to the moving core and the other part thereof is used as a seal for working fluid based on fitting to the pressure tube 2, thereby to reduce magnetic loss in the magnetic path from the yoke 10 to the moving-core 1.

IPC: H02K27/04
Filed: 1989-06-14
Abstract: PURPOSE:To improve the efficiency of a motor by arranging a plurality of coils so that magnetic flux generated on the core of a stator fixed on a counter load side bracket facing the core of a rotor, with the stator may be led in the direction of the rotor. CONSTITUTION:When one side of a stator 25 is set to be of a pole N and the other side is set to be of a pole S, then on both sides, current flows also to coils 26 connected to windings 25a, and a magnetic field is formed. Accordingly, the direction of magnetic flux generated by the stator 25 is changed by the magnetic field formed by the coils 26 on both sides, and is to be directed to a rotor 21. Accordingly, the magnetic flux which does not cross the rotor 21, is to cross the winding of the rotor 21, by means of the coils 26, and the total number of the magnetic flux crossing the winding 21a of the rotor 21 is increased. Accordingly, as shown by rotational force F=BIL sin theta (B; magnetic flux density, I; current, L; length of copper wire), a greater rotational force can be obtained, if with the same consumption power and with the same length.

Title: Heat pump thpe air conditioner
Inventor: OKUZAWA YOSHIYUKI
IPC: F25B13/00
Filed: 1980-10-29
Abstract: PURPOSE: To elevate thermal efficiency by applying a phase advancing current to generate heat at a part of the winding of a motor when the heating capacity falls short in a heat pump type air conditioner without an auxiliary heat source.  
     CONSTITUTION: During the heating operation in the winter season, when the room temperature exceeds a difference from a set temperature, a commander 12 provides a capacity increasing command to charge an electromagnetic switch 11 and a relay 13 to run a compressor 1 while a capacitor 15 is energized. Consequently, a compressor motor 1M is interrupted from the phase S with the action of a relay 13 and a terminal V is connected to the phase T through the capacitor 15, so that it is shifted to a single operation between the phases R and T resulting in a rise in the winding temperature. Heat generated contributes to a rise in the temperature of a gas discharged from the compressor 1. This increases the heat level of a refrigerant to be subjected to heat exchanger with room air through a room side coil 3 thereby enhancing the heating capacity.

Abstract: PURPOSE:To simply enable the speed-up and the increase in density of a bi-polar integrated circuit by reducing unnecessary electrode wiring margins for base contact and collector contact. CONSTITUTION:By reduction of the electrode margins for the base contact 10B and the collector contact 10C by DELTAB-DELTAB' and DELTAC-DELTAC' respectively; the distances LEB between contacts is reduced to LEB, and the base parasitic resistance is reduced, leading to realization of element speed-up, and to realization of the reduction of element area is addition to the reduction of the distance LEC between contacts to LEC'. Here, the reduction of margins of the base B and the collector C enables substrate attack due to etching, as for the base contact 10B, to give no influence on the characteristics even when the attack generates more or less, because of the formation of a contact 5B and a graft base GB having a depth 3-4 times as large as that XjEB of a normal E-B junction in its neighborhood.
