Title: Fm high frequency tuning circuit
Inventor: MATOBA TSUNEAKI
IPC: H03G5/24
Filed: 1981-05-28
Abstract: PURPOSE:To prevent cross modulation and intermodulation due to an interference wave, by using a varactor diode as an input coupling capacitance connected to a tuning circuit and controlling the capacitor with a voltage proportional to a received electric field strength. CONSTITUTION:An input applied to an antenna input terminal 1 is given to a tuning coil 3 via a DC-cut capacitor 27 and a varactor diode 28. On the other hand, a broad band AGC voltage from a level detector 24 is applied to a connection point with the capacitor 27 as a control voltage for the level detector 24 via a resistor 18. As the output voltage of the level detector 24 increases, the capacitance of the varactoradiode 28 is reduced, the Q of the tuning circuit is increased and the pass band characteristics can be narrowed. Thus, the attenuation  of the interference wave is increased to a desire signal, allowing to improve the  cross modulation and intermodulation.

Title: Method and device for ventilating water
Inventor: GEORUGU URUMAN
IPC: C02F3/08
Filed: 1979-07-02
Abstract: An improvement for the aeration of the water and combining the aeration with the cleansing of the water by a biological cover, in which one or several circular disks rotate in a clarifying reservoir about a horizontal shaft. These carry at their circumference annularly bent funnels which extend in part above the water surface and continuously converge in direction from the inlet opening to the outlet opening. Above the water surface air enters through the inlet opening into the funnel and below the water surface water enters into it. Because the funnel converges continuously, both water and air are accelerated and compressed in the funnel. The compression assures that the amount of oxygen which is soluble in the water and can be accepted by the same from the air, is substantially increased. The biological cover forms on the disks and on the outer surface of the funnel.

IPC: G01N21/84
Filed: 1982-05-17
Abstract: PURPOSE:To accurately detect the ruggedness in the form of an electric signal by a method which is intended to obtain the difference between original signals resulted from sampling displacements of the tire side wall, which are detected by a detector, at predetermined time intervals and signals generated to be delayed by the predetermined number of samplings. CONSTITUTION:Displacements on the side wall surface of a rotating tire is detected by a detector 1 to generate signal voltage in proportion to the detected displacement amounts and signal voltages having the same values and delayed by the predetermined number of samplings. The difference between both signals is calculated in an arithmetic unit C to take out those displacements only which result from fine ruggedness present on the tire surface. By so doing, even with a simple circuit configuration, measure accuracy can be increased and fine ruggedness can be surely detected in the form of an electric signal.

Abstract: PURPOSE:To get a turbine vacuum pump which keeps high performance of a regenerative pump by arranging a regenerative pump which consists of blades arranged on axially projecting parts of a rotor and ventilation flues arranged o a periphery of a stator in a face-to-face relation with the blades. CONSTITUTION:A regenerative pump is made up of forward circular blades 5 of a stator 6 of the regenerative pump, formed on axially projecting projecting parts of a rotor 1 of the regenerative pump and ventilation flues 7 formed on parts which are axially opposed to the circular blades 5.
