Title: Crystal oscillator
Inventor: SATOU HIROCHIKA
IPC: H03H9/19
Filed: 1979-03-12
Abstract: PURPOSE:To realize a small size and high accuracy for the GT-cut crystal oscillator by suppressing the vibration energy loss. CONSTITUTION:The consideration is given to the conditions under which the deviation amount becomes nearly zero at the support part for the GT-cut crystal oscillator. And thus it is found that the ratio between width W1 of the support part and width W0 of the crystal plate must be set larger than 0.75. Furthermore, it is found that the deviation amount is made zero according to the form of the support part and also based on the consideration through the finite element method. With such ideal support part, the supporting problem can be solved for the GT-cut crystal. Thus a small-size and high accuracy crystal oscillator can be obtained with about 0.8MHz-5MHz. In addition, the mass productivity can be increased owing to the structure capable of the unified formation.

IPC: F03B17/00
Filed: 1980-03-10
Abstract: PURPOSE: To generate reliable turning moment under the water, by setting an open end of an air pipe of air pump below a rotary path of buckets.  
     CONSTITUTION: An open end 7a of air pipe 7 is set at a position below an underwater rotary device, being slightly shifted from the vertical line passing a rotary shaft 1 of the rotary device toward the forward direction of rotary discs 3, 4, 5.

Filed: 1979-03-16
Abstract: PURPOSE:To reduce the number of sensors and maintain higher safety, by providing a separable connector coupling portion on a casing wiring portion and providing a casing with a penetrated portion which is shielded on an outside lead-out portion and sealed up to prevent internal gas from leaking. CONSTITUTION:A sensor cable 4 is a coaxial shielded cable which is less affected by an external noise and another noise due to the deformation of the cable itself. The sensor cable extends to the penetrated portion 7 of a casing 6 through an inside connector coupling portion 5. This coupling portion is made of a coaxial connector. In the case of the dielectric strength test of a stator winding or a similar case, the cable 4 is disconnected at the coupling portion 5 and enough dielectric strength is set to insulate the casing 6 from sensors 3, 3'. The shielded section 8 of the led-out portion of the cable 4 is directly coupled to the grounded casing so that a voltage produced by electrostatic induction is released to the ground. This results in maintaining higher safety.

Title: Detection of defective insulator
Inventor: KATO KAZUHISA
IPC: H01B17/00
Filed: 1989-02-09
Abstract: PURPOSE:To easily detect in a string unit whether there is a defective insulator in an insulator string by detecting an allotted voltage of an insulator with a detector installed at a specific insulator in an insulator string device. CONSTITUTION:A detector is installed to a specific insulator of an insulator string device to detect an allotted voltage of one insulator. In case all the insulators of an insulator string are sound, the voltage charged to a conductor 5 is allotted to all the insulators, but if a defective insulator whose insulation resistance drops is included in the insulator string, the voltage to be allotted to the defective insulator is to be allotted to the remaining sound insulators. Resultantly, in case of the defective insulator string, a detected allotted voltage is greater than an allotted voltage of a sound insulator string regardless of a position where the detector 6 is installed, so that when the detected allotted voltage exceeds an allowable value, it can be judged that a defective insulator is included in the insulator string device. Thereby, it is possible to detect a defective insulator.

Filed: 1985-02-19
Abstract: PURPOSE:To decrease remarkably the occupied area of a pulse generating circuit on a semiconductor integrated circuit by forming the pulse generating circuit with a delay circuit, two NOR circuits (or NAND circuits) and an AND circuit (or OR circuit). CONSTITUTION:The pulse generating circuit is formed by the delay circuit 501, the two NOR circuits 502 and the AND circuit 503. Then, the pulse width T of an output signal OUT is nearly equal to the delay time of the delay circuit 501. That is, the pulse width T is set to a desired value by having only to adjust the delay circuit 501. In forming the pulse generating circuit by CMOSes, 18 transistors and one capacitive element, that is, 19 circuit elements in total are required. Thus, the number of components is reduced remarkably in comparison with a conventional circuit. As a result, the occupied area of the pulse generating circuit is decreased remarkably on the semiconductor integrated circuit.
