IPC: H01M2/08
Filed: 1992-10-28
Abstract: PURPOSE: To effectively take in air, prevent a flux of an electrolyte, and make a multilayer film functional as a safety valve by forming a seal for a multilayer film with putting an inner layer of film B between outer layers of two films A, making a melting point of the outer layer lower than that of the inner layer, and implementing a complete connection between the inner and outer layers. CONSTITUTION: This air alkaline battery 2 is provided with an active component, a organic polymer sealing member, and a multilayer film 26 in its iron vessel 4. The film 26 has an inner layer of two polytetrafluoroethylene films and an outer layer of two polypropylene films holding the former there between, wherein a melting point of the outer layer is lower than that of the inner layer. As this film 26 is subject to heat seal in its peripheral edge a perfect combination is implemented between the outer layer and the inner layer of the film 26. The inner layer has a porosity for air, while prevents a flux of an electrolyte from the battery 2. Thereby the film 26 effectively takes in air, prevents the flux of an electrolyte, and can function as a safety valves.

Filed: 1999-11-19
Abstract: PROBLEM TO BE SOLVED: To reduce torque ripples without producing a counter torque by providing rotor salient poles and stator salient poles opposed to each other at a mechanical angle of 180 deg. and setting the numbers of rotor poles and stator poles to even numbers. SOLUTION: With respect to a reluctance motor its stator 1 and rotor 2 are so constituted that the number of poles B and the salient-pole arc angle Y of the stator 1 and the number of poles A and the salient-pole arc angle X of the rotor 2 satisfy Equations I-IV (where, q is a number of phases; m and n are natural numbers; z is the greatest common divisor of A and B; and αis negative torque margin angle). Exciting coils C1-C6 are wound on the stator salient poles 1A of the stator 1 opposed to one another at a mechanical angle of 180 deg.. Continuous torque is obtained by calculating the interval of starting the energization of the coils C1-C6, obtaining an energization width for performing electrical tandem driving, and applying power with an inductance change width.  Thus, torque ripples can be reduced by electrically tandem-driving the coils C1-C6 without producing counter torque.

Title: Vibrated excited hydrogen cell
Inventor: SASAOKA CHIAKI
IPC: C23C16/44
Filed: 1993-12-27
Abstract: PURPOSE:To provide a vibrated excited hydrogen source efficiently supplying vibrated and excited hydrogen molecules. CONSTITUTION:A cell consists of a hydrogen-molecule introducing pipe 13, in which a hydrogen permeable film is sealed, a heat source for the hydrogen permeable film and a palladium-evaporated copper sheet 11 as the hydrogen permeable film, and a deposited surface is faced to the inside of the hydrogen- molecule introducing pipe 13. Hydrogen atoms adsorbed onto a copper surface are thermally desorbed from the surface as hydrogen molecules by association and desorption. The desorbed hydrogen molecules are brought to the vibrated and excited state. Since the dissociation efficiency of hydrogen molecules on the copper surface is low, however, hydrogen atom concentration on the surface is low, and the quantity of vibrated excited hydrogen molecules formed is reduced extremely. Hydrogen molecules are dissociated in an atomic shape by a palladium film evaporated on the rear of copper in the hydrogen vibrated excited cell. Accordingly, formed hydrogen atoms diffuse in the palladium film and a copper thin-film and reach the surface, and are associated and desorbed as vibrated and excited hydrogen molecules.

Inventor: ARITA YOJI
IPC: H02K1/27
Filed: 1990-11-30
Abstract: PURPOSE:To reduce a cogging torque by adding a specified number of higher- order auxiliary magnetic poles in correspondence to the number of salient poles and the number of magnetic poles of a permanent magnet in a magnetic flux generating region of the permanent magnet. CONSTITUTION:In a motor having a magnetic field system part 1 which has (m=2) pieces of magnetic poles and (p=18) pieces of salient poles which are opposite to the magnetic field system part 1 that are magnetically equivalent, the number of poles of an auxiliary magnetic pole 10 which auxiliarily adds a higher mode to a primary magnetic pole is 34 or 38 according to the formula where q=1 (the greatest common measure of m/2 and p), i=18 (p/q) and j=1 (since the independent magnetic flux mode where a cogging torque has a cycle of 20 deg. is the 9th order in this motor, the value of 'j' should be 1, which is the basic mode, to reduce the cogging torque) when a pair of magnetic poles (N pole and S pole) is one cycle against the direction of an angle of rotation of the motor. By adding the higher-order auxiliary magnetic pole to the primary magnetic pole, a cogging torque can be reduced to a substantially neglible quantity.

Title: Freshness preserving storage compartment
Inventor: TAJIKA TERUMITSU
IPC: A23B7/12
Filed: 1987-12-25
Abstract: PURPOSE:To provide a freshness preserving storage compartment which can reasonably reduce the quantity of breathing of fresh foodstuff by supplying CO gas into the storage compartment so as to increase the CO concentration and reduce the O2 concentration therein after cooling the storage compartment down to a specified temperature. CONSTITUTION:Upon switching ON, the storage compartment 1 is cooled by a cooling unit 2. When the temperature of the storage compartment reached the set temperature, a serial connection is established with the power source 8 and switch 9. By means of a heat sensing part 15 of a thermostat 14, a CA unit is operated to introduce CO gas, and so, the CO concentration increases and the O2 concentration decreases. When the start switch 9 is turned OFF, the cooling unit 2 and the CA unit 7 are turned OFF. When the start switch 9 is thereafter turned ON, the same control procedures are followed, and, when the temperature of the storage compartment 1 reaches the set temperature again, the same control procedures are also followed. Therefore, the quantity of breathing of fresh foodstuff in the storage compartment can be reduced without causing undue burden on the biological action, allowing a storage for a long period of time.

Title: Constant voltage power supply circuit
Inventor: OTSUKI MAKOTO
IPC: G05F1/56
Filed: 1987-12-28
Abstract: PURPOSE:To reduce the capacity of a capacitor connected to both ends of a load by connecting a switching means in series between the emitter and the base of a pnp transistor TR and therefore the switching means is turned off when a resistance and the power supply voltage have the short circuits at the earth side. CONSTITUTION:The TRQ4 and Q5 are turned off by the drop of the power supply voltage Vin and the voltage Vcc is kept at a fixed level to a load R set at the collector side since no current virtually flows to the earth side from the base of a TRQ1. Then a reverse transistor phenomenon where the current flows adversely to the base side from the collector side of the TRQ1 since the base voltage of the TRQ1 is higher than the Vcc of the collector side. As a result, the level of the Vcc is just reduced to the load R set at the collector side of the TRQ1 in accordance with the time constant decided by the load R and a capacitor C connected to both ends of the load R. Thus the capacitor C having small capacity can be selected.
