Title: Bevel-type crystal oscillator for watch use
Inventor: TAKATSU HIDETOSHI
IPC: G04G3/00
Filed: 1978-09-11
Abstract: PURPOSE:To obtain the good frequency temperature characteristics which produces no secondary vibration at all to the temperatures of -20 deg.-+60 deg.C by setting the diameter of the flat part of the value of the specified range after bevelling the 4.2M Hz band bevel-type crystal oscillator for watch use. CONSTITUTION:One side of the rectangular and square bevel plates or diameter D of the circular bevel plate is formed 8.5-9.0mm. At the same time, slope polishing process 2 is applied to crystal oscillator raw plate the electrode diameter of which is set 4.5-6.0mm, and flat part diameter FDphi is set 4.1-4.5mm after polishing. Thus an oscillator is obtained. The oscillator thus formed does not produce the secondary vibration at all in the temperature range of -20 deg.-60 deg.C as shown in the figure. Furthermore, the equivalent resistance can be reduced down less than about 20OMEGA, thus obtaining food frequency temperature characteristics for watch use.

Title: Brake controller for electric motor vehicle
Inventor: KARITA TAKEHIKO
IPC: B60L7/22
Filed: 1977-09-19
Abstract: PURPOSE: To avoid a voltage applied to non-energized section that follows the dead section, by separating a dynamic braking circuit from the feeder line in a non- energized section from after the one with a detection made that the regenerative vehicle come into non-energized feeder section.  
     CONSTITUTION: If a regenerative vehicle, under a regenerative braking operation, enters a non-energized feeder system, a filter condenser voltage Vcf comes to be overvoltage, with an output produced in an overvoltage detector OVD. With this output firing a thyristor Th, a damping current is absorbed by a resistor R, simultaneously with a switch S disconnected. When disconnected the switch S, a dynamic braking circuit, including a filter condenser Cf, is isolated from a pantograph collector PG, and the filter condenser voltage Vcf is not applied to a divice for detecting a voltage Vs of trolley wire. Consequently, after a disconnection of the switch S, an existencs of output from the device for detecting a voltage Vs of trolley wire will discriminate whether energized or non-energized section, and if in non-energized section, the dynamic braking operation will be made continued

Title: Rotary hydraulic machine
Inventor: FUKAI KIYOTATSU
IPC: F03B17/04
Filed: 1979-09-03
Abstract: PURPOSE: To enable the attainment of economical utilization in the sourface of electric power by utilizing the pressure energy given to water again through conversion thereof into the kinetic energy.  
     CONSTITUTION: When an electromotor 11 is fed, the main rotary shaft 2 rotates and the rotor of a generator also rotates therewith. A water conduit 1 is filled with water and the water is given the pressure energy by the centrifugal force in and around the nozzle of Pelton wheel. When a fixed speed is achieved, a servomotor is fed to convert the pressure energy into the kinetic energy with adjustment of a needle valve and thereby a waterwheel is rotated. A generator 49 feeds the electric power to the outside. When the waterwheel rotates, a wheel 47, rotating on a ring-like gear 46, gives a force to rotate a disc 19, helps the electromotor 11 and thus reduces the quantity of electric power to be fed from outside. The water used for Pelton wheel passes a conduit plate 26 and is led to the periphery of the disc 19. A part of the electric power led out of the generator 49 is supplied to an electromotor 12, whereby the electric power fed to the electromotor 11 from outside is reduced.
