Title: Method and apparatus for actuating motor type brake
Inventor: RIHIARUTO BUIRUKE
IPC: F16D65/28
Filed: 1981-03-18
Abstract: An electromechanically reciprocable load has a driving spring tending to displace it from a retracted position into a working position upon the release of a locking brake. The spring force is opposed by the countervailing force of an electric motor which, during the working stroke, is progressively reduced in keeping with the diminishing force of the relaxing spring. When the load includes a caliper of a power brake arresting a rotary element in its working positon, the motor is controlled by a bridge circuit with two potentiometers whose wipers are entrained, with a relative lag, by the load so as to establish a variable null position advancing with progressive wear of the brake linings in order to keep constant the travel of the load during a return stroke brought about by the energization of the electric motor with an overriding signal. An accelerometer monitors the speed of the rotary element to soften the impact of sudden deceleration in the final phase of the brake-actuating stroke by temporarily increasing the countervailing motor force if the rate of deceleration exceeds a predetermined threshold.

Filed: 1978-04-04
Abstract: PURPOSE:To remarkably relax speed-change shock due to shift operation in lock-up state by arranging an orifice in a reservoir circuit and delaying the speed of flowing out of oil from a lock-up oil chamber. CONSTITUTION:When the vehiele speed reaches above 40 Km/h and the ports 36 and 37 of a first spool valve 30 communicate, if front clutch pressure B for shifting from the second to the third speed is supplied, a secondary spool 40 shifts leftward, and drainage to a reservoir circuit 200 through ports 45 and 46 begins, or the decompression inside a lock-up oil chamber 27 is perfomed relatively gently, due to the orifice 47 of the reservoir circuit 200. Accordingly, lock-up is completed before the completion of shift, and the generation of speed change shock due to the shifting in lock-up state can be prevented. Also the pressing of a clutch piston 20 to a converter cover 6 is preformed gently, and the impact due to clutch connection in lock- up state is remarkably relaxed.

Title: Crystal oscillator for watch
Inventor: WAKASUGI MAKOTO
IPC: H03H9/02
Filed: 1978-04-04
Abstract: PURPOSE:To secure the flat frequency temperature characteristics for the crystal oscillator as well as to increase the accuracy by connecting the electrostatic capacity formed by a pair of metal films provided on the surface of the sealed container in parallel to the electrostatic capacity the crystal oscillator itself owns. CONSTITUTION:The airtight container of the crystal oscillator composed with bottomed container 1 and the plate-type component 2, and metal thin film 5 and 6 are formed on the surface of conponent 2. And film 5 and 6 are connected to the electrode of crystal oscillation bar 3 to produce electric field E, and thus the electrostatic capacity which is determined by gap width g and continuous length l of the gap of field E can be secured. In other words, both g and l are set freely to form the electrostatic capacity identical to the parallel capacity possessed by bar 3. And the capacity of the crystal oscillator can be set to the proper value by controlling the electrostatic capacity produced between film 5 and 6. For example, if film 5 is cut off like A by the laser beam, the electrostatic capacity reduces.

Filed: 1987-02-23
Abstract: PURPOSE:To enable a wavelength to be always directly read for a grating with the arbitrary number of grooves by constituting a grating rotating mechanism and a wavelength feed mechanism by interchangeable and independent units and mechanically coupling both the units. CONSTITUTION:A grating rotating mechanism unit 2 is rotatably supported and a grating G is mounted on a holder 12 integrally connected to an arm 6 via a rotating shaft 5. On the other hand, a sliding plate 11 against which the arm 6 abuts engages a driven feed screw 8 so as to be allowed only to move in the axial direction of the screw 8 in a wavelength feed mechanism. The unit 2 is fed 3, 4 to the bottom surface of a base 1 and the unit 7 is mounted on the end portion of the base 1. Accordingly, a sine bar mechanism is constructed by making the rotating mechanism including the grating and the wavelength feed mechanism independent of each other as one and the other units. Thus, since the rotating mechanism prepared in accordance with the number of grooves of the grating and the wavelength feed mechanism are interchangeable with each other, a wavelength can be always directly read for the grating with the arbitrary number of grooves.

Abstract: PURPOSE:To inexpensively generate with a simple structure by opening and closing a coil in a magnetic field. CONSTITUTION:A coil 3 is placed in a magnetic field between magnets 1 and 2, and the contact 4 of the coil is opened and closed by a controller 5. When the circuit of the coil 3 is opened, a current will not flow, but when the coil is closed by the controller 5 and the coil 5 is thus closed in a closed circuit, a current is produced, and is then attenuated according to the time constant of the coil 3. When the controller 5 is then operated to open the contact 4 and the contact 4 is immediately closed, the coil 3 becomes newly a closed circuit, and a current is again produced and is then attenuated. When this operation is repeated, the current produced in the coil 3 is produced.
