Title: Ultrasonic actuator
Inventor: ASHIZAWA TAKATOSHI
IPC: H02N2/00
Filed: 1994-02-15
Abstract: PURPOSE:To improve the performance such as drive efficiency, drive force, etc., by making the length in drive direction of the contact part, with the sliding face of an elastic body, of a mover twice or more times as long as the wavelength of progressive vibration waves. CONSTITUTION:Multilayer piezoelectric members 121 and 122 are oscillated by drive signals, and progressive waves are generated in an elastic body 111, and elliptic motion accompanying the progressive waves is generated at the drive faces 111a. Sliding parts 141 and 142 are driven, being pressed against the drive faces 111a, and receiving drive force from the drive faces 111a of the elastic body 111. A coupling means 143 shifts with the sliding parts 141 and 142, because they are engaging with respective sliding parts 141 and 142. If the length in drive direction of the sliding part 141 is double the wavelength of the progressive vibration waves or more, the mover 102 inclines, so the end face of the sliding part 141 can be prevented from contacting the bottom of the progressive waves. Accordingly, it is reduced for the sliding part 141 to be subjected to the resistance opposite to the advance direction, and the drive force or drive efficiency can be improved.

Title: Ultrasonic measuring device for distance
Inventor: SUZUKI KENICHIROU
IPC: G01S15/10
Filed: 1982-02-09
Abstract: PURPOSE:To measure a distance accurately by controlling the opening and closing of a gate at constant timing, and thereby evading the effect of jamming reflection and noise. CONSTITUTION:A gate 19 for tracking is inserted, behind a gate 12, in a system ranging from the input side of an RF amplifier circuit of an ultrasonic distance measuring device to the output side of a reception discriminating circuit, and a signal l for opening and closing the gate is inputted in the gate 19 from a gate control unit A. The gate 19, which is opened only during a period wherein the signal l is inputted, follows a target, since a distance information output Lo changes when the target moves. Even when jamming reflection and noise are generated temporarily outside the gate 19, they can not pass the gate 19, and therefore, only a reflection echo is received, discriminated and delivered. When the reception and discrimination of the reflection echo are discontinued, an output DELTAlo of an integrator 24 turns small, and the gate 19 starts to open. When a reflection echo is received and the discrimination is started again, a hold control circuit 30 is reset. When the output DELTAl of the integrator 24 turns large, the gate is closed again to a fixed gate width.

Title: Optical pickup position detector
Inventor: DOI OSAMU
IPC: G11B7/085
Filed: 1990-01-29
Abstract: PURPOSE:To always conduct a brush and a resistor for position detection and to improve the position detecting power of an optical pickup by using the brush for position detection, dividing this brush in the transverse direction perpendicular to the tracking direction of the pickup and previously varying the respective brush lengths. CONSTITUTION:The front of the brush 1 to be brought into contact with the optical pickup is divided to the brush pieces a to d of respectively different lengths by grooves 3 and all these pieces are brought into sliding contact with the optical pickup in the direction perpendicular to the tracking direction 6 of the pickup. The brush 1 is constituted in such a manner. Any of the brush pieces a to d maintains the contact state with the resistor 5 for position detection even if the load to hinder the movement of the optical pickup 4 acts casually and uniformly as a contact pressure on the brush 1 by a certain cause at the time of fixing this brush 1 to the optical pickup 4 and sliding the same in contact with the resistor 5 and even when the repulsive force acts like the brush 1' to float the brush. The brush 1 and the resistor 5 are thus maintained always in the conducting state.

Filed: 1984-02-03
Abstract: PURPOSE:To contrive miniaturization, lightening and reduction of cost by arranging a space in the middle of the laminating direction of laminated plates of power transformer and inserting an evaporation part of a heat pipe into the gap to obtain the good heat conductive condition. CONSTITUTION:The large quantity of heat generated from a power transformer 3, a magnetron 13 and an electron range control block 14 at cooking operation of an electron range 1 is emitted by heat exchange with the air flow sent by a cooling fan 12. The heat filled insided is deprived as the evaporation heat which evaporates an operation liquid inside an evaporation part 7a of a heat pipe 6 and is carried to a condensatio part 8 through a pipe 9. Then the heat is exchanged with the air flow sent from a cooling fan 12 by the condensation part 8 and a dissipation fin and is emitted. Because the heat inside the power transformer 3 can be taken out efficiently, the winding diameter of coil of power transformer 3 is formed thinly and a lamination plate 4 can be made smaller. Accordingly, miniaturization and lightening of the main body of power transformer 3 can be contrived and also cost can be reduced.
