IPC: A47J37/06
Filed: 1996-03-25
Abstract: PURPOSE: To heighten the storage holding force by providing the outer bottom of a cooker with a pushing holder of storage stand to be stored. CONSTITUTION: The storage stand 8 is composed of a bearing shaft 8a which is, freely reciprocatably and rotatably inserted to a bearing 9 which is fitted onto the outer bottom of exterior gear 2, a leg 8b which serves as a base during the storage, and a nipper 8c which nips, coworking with the bearing shaft 8a, a hot plate when the setting is made to the designed layout of storage. In order to push and hold the nipper 8c on the lower surface of exterior gear 2, and thus, not to move the nipper 8c of stored storage stand 8 up and down at all, a hemispheric protrusion 15 functions to hold up the opposite bearing shaft 8a from the central line of bearing 9. During the storage of storage stand 8 in the outer cooker bottom, the holding force can be heightened for that storage, because the storage stand 8 is pushed and held by the pushing holder.  The stored storage stand 8 does not fall down during the washing of cooker body as well.

Title: Braking circuit for inverter device
Inventor: OOGAMI MASAKATSU
IPC: H02M7/48
Filed: 1980-05-22
Abstract: PURPOSE:To prevent the wasteful power consumption of a brake resistor by stepwisely increasing the brake resistance value inversely proportionally to the rotating speed of a motor. CONSTITUTION:The series units of contacts MC2, MC1, brake resistors R2, R3 are connected with a braking circuit 2 between power lines, and the resistance values of the resistors R1-R3 are set at 3R. While the rotating speed of the motor M is N0-2/3N0, contacts MC1-MC3 are all closed, and the sum of the brake resistors become R. While the rotating speed of the motor is 2/3N0-1/3N0, the contact MC3 is opened, but the contacts MC1, MC2 continue the closed state. While the rotating speed of the motor is 1/3N0-0, the contact MC2 is opened, but only the contact MC1 continues the closed state. That is, the contacts MC1-MC3 are so controlled that the brake resistance values are stepwisely increased corresponding to the rotating speed of the motor M as to the opening and the closing of the contacts. Since the brake resistance value at the braking time is accordingly increased inversely proportionally to the roating speed of the motor M, the wasteful power supply from the power source can be suppressed.

Title: Copying apparatus having original feed mechanism
Inventor: YOSHIMURA SHIGERU
IPC: B65H5/00
Filed: 1979-06-01
Abstract: PURPOSE:To let smooth automatic original feeding be done by performing destaticizing of the orignal platen surface from the side opposite from the original  placement side of the original placement member while discharging the original  before the next original comes. CONSTITUTION:A destaticizing needle 15 is held in the position away in the scanning direction A by a distance l1 from the exposure opening, and moves in the scanning A direction together with moving mirrors 4, 6. Upon ending of the exposure scanning, it moves in the B direction together with the moving mirrors 4, 6, but at this time, the original 8 which has completed exposure is also moved in the B direction while sliding on glass plate 3. The next original is sent out from a feed part 10 synchronously with the original 8 by leaving the specified spacing l2 larger than l1. While maintaining the position delayed from the trailing end of the original 8 and advanced from the leading end of the next original, the destaticizing needle 15 moves in the B direction to destaticize the glass position where no original is placed. This considerably enhances the destaticizing effect.

Title: Composite loop antenna for inductive radio
Inventor: IGARASHI KEISUKE
IPC: H01Q7/00
Filed: 1987-03-25
Abstract: PURPOSE:To prevent wide space from being occupied and to miniaturize a frame-shaped composite antenna, by arranging both loop antennas at a point where no mutual electromagnetic coupling is generated, or in the neighborhood of the point. CONSTITUTION:When two frame-shaped loop antennas 12-1 and 12-2 are separated little by little from each other, the point where no more electromagnetic coupling with the antenna 12-2 is generated can be found by setting magnetic flux phi1 advancing from upside to downside and magnetic flux phi2 advancing from the downside to the upside adversely equal and negating them with each other. At this position, the two loop antennas are arranged adjacently. In such a way, since no electromagnetic coupling is generated, they form a composite loop antenna with a few area of dedicated space, and a remarkable effect can be obtained in practical use.

IPC: H01S3/038
Filed: 1983-04-20
Abstract: PURPOSE:To prevent the generation of a poisonous gas, to inhibit the lowering of a laser output and to obtain the laser output stable for a prolonged term by coating the surface of a discharge limiting material with an inorganic insulator, which does not change a composition on the mixing of a laser medium gas. CONSTITUTION:When high-frequency high voltage is applied to a pair of dielectric electrodes 11, an intense silent discharge is generated from a discharge limiting material 16, fillers 17 and the surfaces of the electrodes 11 not coated with an inorganic insulator 19, and the surface of the insulator 19 in the vicinity of the electrodes 11 is exposed to the silent discharge. Consequently, the titled gas laser device is constituted so that each surface of the limiting material 16 and the fillers 17 as the generating sources of a poisonous gas is coated with the inorganic insulator 19, which does not generate the poisonous gas even when it is exposed to silent discharge. As a result, no poisonous gas is generated because the limiting material 16 and the fillers 17 are protected from the heat of silent discharge and an electron bombardment, thus preventing the change of a composition on the mixing of a laser medium gas. Accordingly, a laser output does not lower, and the stable laser output is obtained.
