Title: Indicator for ground fault point of transmission line
Inventor: FUKUI NOBUTAKA
IPC: G01R31/08
Filed: 1988-03-15
Abstract: PURPOSE:To easily discover a ground fault position by mounting a current detecting Rogowski coil at an iron tower horizontal member perpendicular to a direction of the installed power wire of a transmission line, and integrating a current detected by the coil. CONSTITUTION:When a current 5 flows through a ground fault point 3 from a power wire 1, a ground fault trouble point occurs in either right or left of an iron tower toward the direction of a transmission line. Accordingly, a trouble current 5 also flows to a horizontal member 4. A Rogowski coil 8 detects only a trouble current flowing to the member 4 around the coil due to its characteristic. A voltage proportional to the ground fault current flowing to the member 4 is amplified at commercial frequency component by an integrator 9, and fed to a display unit 11. The unit 11 is electrically operated when the voltage exceeds a predetermined operation level.

Title: Variable capacity compressor
Inventor: NAITOU TOSHIHARU
IPC: F04B27/02
Filed: 1982-04-08
Abstract: PURPOSE:To make the discharging capacity of the compressor variable without enlarging the size thereof so much by a method wherein a cylinder is provided with a sub suction chamber, supplying refrigerant into the cylinder, and a suction chamber, distributing and supplying the refrigerant into the sub suction chamber, while a cylinder throttle valve, intercepting the flow of the refrigerant, is arranged in a part of a suction flow path. CONSTITUTION:When suction gas paths 40, 41 are closed, a plunger 64 closes the opening 59b of a low-pressure introducing hole 59 by receiving the energizing force of a spring 65 and only a high-pressure introducing hole 58 is opened for a pressure chamber 56. As a result, the high pressure in a sub discharging chamber 23 is impressed to the pressure chamber 56 and is delivered to the back pressure of the throttle valve body 48 through a pressure introducing hole 57. Accordingly, the valve body 48 is pushed against the surface 44a of a valve seat by the discharging pressure of the refrigerant in the sub discharging chamber 23 and thereby closing the suction gas paths.

Title: Removing method for product in die casting machine
Inventor: OKUYAMA TERUO
IPC: B22D17/22
Filed: 1981-04-21
Abstract: PURPOSE:To trim products while preventing the inclination of the products and to improve working efficiency in a die casting machine that operates cooperatively with a product removing device by gripping a sprue after casting then making take-off force variable and tuning the same to the ejection action. CONSTITUTION:Right after casting of products, the sprue part (b) of the products is gripped with gripping jaws 5 of a product removing device 4. Next, the products are ejected from the cavities of dies by operating the ejection pins 3 of a die casting machine and at this same instant, the products are removed by the operation of the device 4 tuned to the ejection action. At this time, the working air pressure of the device 4 is reduced to decrease pulling force thereby allowing the pulling to follow up the ejection action. At the same instant when the products detach from the cavities, the working air pressure is changed over to high pressure to increase the pulling force, by which the products are removed. Hence, the products are removed and trimmed while they are kept free from undue stress.

Title: Digital signal detecting circuit
Inventor: ICHIHARA MASAKI
IPC: G11B20/10
Filed: 1984-03-30
Abstract: PURPOSE:To prevent an error in signal detection due to the variation in the amplitude of a received signal by adjusting automatically the amplitude of not a received multilevel signal, but a reproduced multilevel signal and a reference voltage for level decision making as to a multilevel digital communication system. CONSTITUTION:An operational amplifier 32 adjusts its output voltage, i.e. reference voltage 9 so that the center reference voltage 12 for level decision making is invariably the earth potential. Therefore, reference voltages 9-15 are invariably in constant proportion relation about the earth potential. An integrator output 28 is connected to not a variable gain amplifier, but the reference voltage 15. Consequently, an automatic control loop for the amplitude of a reproduced four- level signal 25 and reference voltages 10, 12, and 14 for level decision making is constituted. Namely, the reference voltages 9-15 are so adjusted that the reproduced four-level signal 25 has the same amplitude with the received four-level signal, and a reference voltage for level decision making which matches with the received four-level signal all the time is generated, so signal detection is performed correctly.
