Patent JP-S57102592-A (JP)
Title: Rotary compressor
Inventor: NAGASAKU HIDEKAZU
IPC: F01C21/08
Filed: 1980-12-16
Abstract: PURPOSE:To always contact the tip end of a vane with the inner surface of a housing in order to prevent the generation of chattering by applying oil pressure to an oil groove formed along almost whole length of a part where the volume of a cylinder chamber increases. CONSTITUTION:A lubricating oil in an oil storing chamber 16b is pushed up to an end surface of an rotary shaft 3 by the pressure of a coolant compressed in a cylinder chamber R, since the oil storing chamber 16b and the rotary shaft 3 are communicated with each other while the pressure of the coolant is applied to the oil storing chamber 16b. Then, the lubricating oil flows into a space between a rotor 2 and a rear side plate 7 from the outer periphery of the rotary shaft 3  and it mainly flows toward a part of the end surface of the rotor 2 where the  volume of the cylinder chamber R increases, further it applies oil pressure to an  oil groove 7c and help a vane 4 to project. Thus, the tip end of the vane 4 always contacts with the inner surface of a housing in a sliding manner, whereas generation of so-called chattering, that is, the generation of noise, caused by  unnecessary movement of the vane 4 in a vane groove 2, can be prevented completely.

IPC: H01Q13/08
Filed: 1988-07-18
Abstract: PURPOSE:To obtain a board band radiation characteristic by providing an annular shaped thin slit to each 1st and 2nd ground conductors at both faces of a strip conductor, providing a cavity forming an aperture shell to one annular shaped thin slit and radiating a radio wave to the other annular shaped thin slit. CONSTITUTION:The amplitude of a current flowing to a strip conductor 5 and that of the sum of currents flowing to the 1st and 2nd ground conductors 3, 4 are made equal to each other but opposite in the directions. Moreover, the radio wave is coupled also with the 1st and 2nd ring shaped thin slits 6, 9 identically with excellent symmetry. Since no large reflecting point of the radio wave exists in the coupled part at that time, the distance from a cross part 7 between the strip conductor 5 and the 1st and 2nd ring shaped thin slits 6, 9 till the tip 8 of the conductor 5 is adjusted properly. Moreover, the characteristic impedance of a tri-plate type strip line comprising the conductor 5 or the like is made coincident with the input impedance of the slot antenna comprising the 1st and 2nd annular shaped thin slits 6, 9. Thus, the matching over a broad band is attained.
