IPC: H01M4/50
Filed: 1984-01-12
Abstract: PURPOSE:To simplify the process for manufacture of an organic electrolyte battery by preventing any deterioration of its performance which might be caused by gas generation by reducing manganese dioxide used in the positive active material by means of an alcohol. CONSTITUTION:During manufacture of an organic electrolyte battery of the thin type, the positive mixture is prepared by mixing manganese dioxide used as a positive active material, a conductive carbon agent and a fluorine-resin-system binder together by the use of water and an alcohol, then drying the mixture before subjecting it to pressure molding. During this process, manganese dioxide is reduced by the alcohol. Additionally, the alcohol contained in the positive mixture is removed by the above process of drying. Therefore there is no possibility that the alcohol remains in the molded positive mixture during the assembly of the battery. By the means mentioned above, it is not necessary to perform the process of preliminary electroc discharge after the battery assembly and the discharge capacity of the battery is increased.

IPC: H04B7/26
Filed: 1990-01-11
Abstract: PURPOSE:To remarkably lower the probability of an interference trouble based on the periodicity of an intermittent radio signal by changing the time interval between signals of the intermittent radio signal periodically. CONSTITUTION:A reception circuit 26b receives a radio signal Sr1, and an intermittent operation is started, however, since it is unknown with which timing of synchronous storage state A, B, or C the next radio signal is received at an initial stage, a switch signal Sd is set at 1 at every synchronous storage stage, and the synchronous storage stage at that time is decided from the timing of a received radio signal Sr2, and the synchronous storage state of the next radio signal Sr3 is decided. In other words, when it is assumed that the synchronous storage state from the radio signal Sr1 to the radio signal Sr2 is in the cycle C, the fact that the next radio signal Sr3 is received in the cycle A is stored in a synchronous storage circuit 25.

Title: Operation controller for ventilator
Inventor: KOBA YOSHITAKA
IPC: F24F7/08
Filed: 1997-01-13
Abstract: PROBLEM TO BE SOLVED: To judge the operation mode of air conditioning equipment appropriately without monitoring cooling and heating operation signals by specifying heat exchange ventilation when the room temperature is lower than the outdoor temperature and ordinary ventilation when the room temperature is higher than the outdoor temperature under the condition that the room temperature is higher than a first specified temperature. SOLUTION: A bypass path 17 is closed and outside air moving through an air supply path 15 is passed through a heat exchanger 4 to be supplied to the room side from an air fan 2. The room air moving through an exhaust path 16 is passed through the heat exchanger 4 and discharged to the outdoor side from an exhaust fan 3. When the air passes through the heat exchanger 4, a heat exchange is performed between the outside air taken into the room side and the room air discharged to the outdoor side. In this manner, so-called heat exchange ventilation is accomplished. On the other hand, the bypass path 17 is opened and outside air and room air are supplied or discharged directly. In this manner, so-called ordinary ventilation is accomplished.  Heat exchange ventilation is specified when the room temperature is lower than the outdoor temperature and ordinary ventilation when the room temperature is higher than the outdoor temperature under the condition that the room temperature is higher than a first specified temperature.

Title: Microwave oven
Inventor: BETSUSOU DAISUKE
IPC: F24C7/00
Filed: 1990-01-11
Abstract: PURPOSE:To allow heating in the same heating compartment regardless of material of a container to be heated by a method wherein a microwave shield plate which covers a heating coil and is made of a dielectric material mixed with metallic fiber, and the metallic fiber is electrically connected to the metallic heating compartment. CONSTITUTION:A microwave shield plate 5 is connected to a metallic heating compartment 3 by electrically-conductive resin. The microwave generated by a magnetron 1 is radiated in the heating compartment 3 and reflected by the microwave shield plate 5 made of dielectric material mixed with metallic fiber 9. As a result, the microwave does not reach a heating coil 4 so that insulated wire which composes the heating coil 4 is not deteriorated as the heating coil is not heated. The metallic fiber is very fine and eddy current is not generated by high-frequency magnetic field generated from the heating coil 4 during induction heating so that the microwave shield plate 5 is prevented from being heated by induction heating. Therefore, an item to be heated in a container 3 placed in the heating compartment 3 can be heated by both dielectric heating and induction heating.

CONSTITUTION:This flange consists of a resin material and is fixed with a metallic plate 20 having plural leg parts 21 projecting radially to the front end of the part to be press-fitted to the base body end of the photosensitive body. The front ends of these leg parts form pointed projections and the diameter of an virtual cylinder formed by these pointed projections is larger by at least >=0.1mm than the inside diameter of the flange fitting part 12 of the base body. The projecting ends of the respective leg parts are preferably required not to exist on the same circumference, the projections at the ends of the respective leg parts to be plural pieces, the ends of the plural projections of the respective leg parts 21 not to exist on the same circumference, and the roots of the ends of the respective leg parts not to exist on the same circumference in order to increase the fixing strength. In addition, the press-fitting is smoothly executed if the at least the ends of the leg parts 21 are bent from the inside of the base body toward the end when these end are fitted into the base body. Such bending is, therefore, preferable.
