Title: Ferrite core and production thereof
Inventor: KINOSHITA KOJI
IPC: C04B35/622
Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To reduce core loss while enhancing initial permeability and saturation magnetic flux density by employing a material containing tetrazinc manganese dioxide partially or entirely as the material of manganese and zinc. SOLUTION: In the forming process of ferrite containing zinc and manganese, a material containing ZnMn2O4 is employed partially or entirely as the material of manganese and zinc. When the ZnMn2O4 reacts on the main material of ferrite, i.e., Fe2O3, uniform dispersibility of metallic atoms is enhanced through evaporation and diffusion and the magnetic loss of a ferrite core is improved. A manganese zinc based ferrite core thus obtained is a so-called general purpose ferrite core principally containing iron oxide, zinc oxide and manganese oxide by 51.0-55.0 mol.%, 5.0-25.0 mol.% and 20.0-40.0 mol.%, respectively, expressed in terms of Fe2O3, ZnO and MnO.

Title: Starting method of reactive power control type cycloconverter
Inventor: MIURA KAZUTOSHI
IPC: H02J3/18
Filed: 1984-04-18
Abstract: PURPOSE:To smoothly start a cycloconverter by sequentially connecting phase advance capacitors divided at a power receiving terminal after a cycloconverter body is started, thereby suppressing a rush current to the capacitors. CONSTITUTION:A reactive power control type cycloconverter CC is started at the body by closing a switch SW0, and phase advance capacitors CAP are connected by closing switches SW1-SW4. A reactive power is controlled by detecting the advance reactive power of an AC power source BUS by a reactive power calculator VAR, and controlled by the prescribed phase control angle alphaP, alphaN through a phase controller pH together with a command value Q from a reactive power instruction circuit QR or a circulating current command value I0 and a load current command value IL. In this case, the capacitor CAP is divided into a plurality (4 in the drawings), and the switches SW1-SW4 are sequentially closed. Thus, it is controlled so that the basic wave power factor at the power receiving terminal becomes 1 at every contact to enter a normal drive operation.

Filed: 1997-03-11
Abstract: PROBLEM TO BE SOLVED: To provide a light source having a compact structure and occupying less space, for an illuminated advertising board, an illuminated signboard, an illuminated display, an illuminated staircase, an illuminated floor, etc. SOLUTION: Light-emitting diodes 12 serving as primary light sources are installed adjacent to the ends of a round light guide rod 13 made of an acrylic resin to serve as a secondary light source, on which light reflecting parts 14 made of conical recesses of equal sizes are arranged on the outer periphery of one side (back) at intervals which get narrower from each end toward the center. Light rays produced by the light emitting diodes 12, after entering the light guide rod 13 through each end, reach each light reflecting part 14 either directly or via reflections inside it, and are radiated outward, via light reflections occurring there, from the outer periphery of the other side (front) radially opposed to the light reflecting parts 14. Therefore, articles or parts to be illuminated which adjoin to the light radiating parts of the light guide rod 13 are illuminated either directly or indirectly via a light guide plate 15 installed adjacent to the light guide rod 13.

Abstract: PURPOSE: To obtain a heat pump apparatus which can perform cooling and heating operation or freezing and refrigerating operation with a compressor to be operated as it is to effectively use the energy of a driving source even when the amount of heat dissipation of a condenser excessively increases compared with the amount of heat absorption of an evaporator. CONSTITUTION: An air conditioner (a heat pump apparatus) has a refrigerant circuit 3 along which refrigerant is circulated passing through a compressor 2, a condenser (an outdoor heat exchanger 6 or an indoor heat exchanger 8), an expansion valve 7 and an evaporator (the indoor heat exchanger 8 or the outdoor heat exchanger 6) in turn. A double-tube heat exchanger (heat supply section) that can supply heat to the refrigerant from outside is installed midway of a high-pressure side refrigerant circuit leading from the outlet of the compressor 2 to the expansion valve 7 via the condenser. The shortage of heat absorption at the evaporator is thereby made up by heat supplied from outside at the double-tube heat exchanger 10 and refrigerant completely evaporates to vapor before it is sucked by the compressor 2.

Title: Cathodically protecting brazing sheet for vacuum brazing
Inventor: KANAI TOMIYOSHI
IPC: B23K35/22
Filed: 1980-06-06
Abstract: PURPOSE: To obtain a cathodically protecting brazing sheet for vacuum brazing having a sufficient protecting effect even after vacuum brazing by forming the core material with an Al alloy contg. In and the coating material with an Al-Si-Mg alloy as an ordinary brazing filler metal.  
     CONSTITUTION: The desired cathodically protecting brazing sheet for vacuum brazing is obtd. by forming the core material with an Al alloy contg. 0.005W 0.1wt% In and the coating material with an Al-Si-Mg alloy used as an ordinary brazing filler metal. In has a very low vapor pressure such as about 10 -6  Torr at  600°C and is not evaporated during vacuum brazing. Accordingly, the core material  has baser potential than the Al alloys of the coating material and other part after  vacuum brazing in succession. As corrosion proceeds, the surface layer is eliminated  to expose the core material, which is then corroded sacrifically to Al and shows a cathodically protecting effect.

Abstract: PURPOSE:To eliminate the need for a commutating reactor and a capacitor and improve the conversion efficiency and the like, by employing a semiconductor element having a self arc-extinguishing capacity in a commutating circuit. CONSTITUTION:Main thyristors SCR21-24 having no self arc-extinguishing capacity as electric power controlling valve are connected in a bridge connection manner and connected to a DC power source 25 and terminals a and d of a primary winding 26P of a transformer 26. The winding 26P is provided with intermediate taps b and c. The voltage between the terminals a-b is made to equal to the induced voltage of a winding 26S1. Under conditions where the SCRs 21 and 24 are conducting and an electric power is being supplied to a load 31 through the transformer 26, when the igniting signal of the SCR21 is shut off and a transistor Tr37 having a self arc-extinguishing capacity as a commutation controlling valve and an SCR41 for selection are made to conduct, the potentials at both ends of a diode 27 for reflux are equal to each other. Therefore, no current flows. Thereby, the SCR21 is reverse-biased by the voltage of a capacitor 36 equivalent to the output voltage of the winding 26S1 and turned off after a given period of time. Accordingly, the Tr37 is extinguished to complete the arc-extinguishing operation of the SCR21.

Title: Manufacture of turbine blade for carburetor
Inventor: YAMAMOTO YUKIO
IPC: F01D5/12
Filed: 1985-04-10
Abstract: PURPOSE:To reduce creeping deformation by putting a turbine blade, while being joined to a shaft, in high-speed rotation at a high temperature and grinding its outside diameter. CONSTITUTION:A turbine blade 3 is joined to a turbine shaft 1, which is then put in rotation at a high temperature corresponding to an actual temperature of exhaust gas and at a rotational speed corresponding to the actual rotational speed of the turbine. This causes generation of a predetermined creep. Subsequently, grinding of the outside diameter of the blade 3 is performed so as to shape it as designed. The blade is put in rotational balance at the same time. The blade, thus manufactured, is prevented from generation of large elongation due to creeping deformation again, which can be reduced beforehand.
