IPC: F15B1/00
Filed: 1988-04-01
Abstract: PURPOSE:To use a small-sized control panel even in case of the use of a large capacity motor by installing a connection part for the electric wire leading pipes on the upper and under surfaces of an electricity receiving box installed onto the side surface of a hydraulic power unit and a starting circuit in the box and leading and connecting the leading pipes from a ceiling and floor surface. CONSTITUTION:An electricity receiving box 21 is installed onto the side surface of a hydraulic power unit 4, and each connection part for connecting an electric power source leading pipe 9 is formed on the upper and under surfaces 22 and 23 of the electricity receiving box 21. Therefore, the electric power source for light receiving on the primary side can be led from the floor surface 2 of a machine chamber 1. Further, since, in the electricity receiving box 21, an electromagnetic contactor and an electromagnetic cut off machine are assembled, a starting circuit consisting of a control panel, electromagnetic contactor, etc. can be separated, and it is enough that only the control and management circuits are accommodated into a control panel 6. Therefore, the presence of a thick electric wire in the control panel is avoided, and the need of a starting circuit which necessitates a large installation space accompanied with the large capacity is obviated, and even in the case of use of a large capacity motor, the conventional small-sized control panel can be used as it is.

Title: Loaded line type semiconductor phase shifter
Inventor: AOKI HIROSHI
IPC: H01P1/185
Filed: 1993-04-07
Abstract: PURPOSE:To obtain the loaded line type semiconductor phase shifter whose phase shift quantity is small by adopting a coupling line having a specific wavelength for part of a loading line. CONSTITUTION:A microwave propagated to loaded lines 4a, 4b connected in parallel with a main line 3 are fed to coupling lines 8a, 8b. In this case, when nearly a 1/4 wavelength with respect to a center frequency is adopted for the length of the coupling lines 8a, 8b, the lines act line a directional coupler. When a microwave is made incident on input terminals 9a, 9b, the microwaves entered from the input terminals are synthesized at isolation terminals 12a, 12b. When the degree of coupling of the directional coupler is decreased, the microwaves are distributed unequally and part of the microwave returned directly to the input terminals 9a, 9b. Thus, the contribution of diodes 5a, 5b to the impedance is decreased. That is, even when a difference between the ON and OFF state of the diodes 5a, 5b is large, the phase shifter with a small phase shift quantity is formed with the loading lines 4a, 4b through the coupling lines 8a, 8b.
