Title: Dry-type capacitor
Inventor: UNAMI KIYOSHI
IPC: H01G2/14
Filed: 1990-02-08
Abstract: PURPOSE:To obtain a capacitor provided with an electrical characteristic whose change with the passage of time is small by a method wherein a compound containing an epoxy group is contained in a capacitor element. CONSTITUTION:A capacitor element is housed inside a container; after that, a synthetic resin is filled and hardened. Capacitors are formed, and their electrical characteristics are compared. As a result, a high-temperature characteristic of capacitors A, B which contain a compound containing an epoxy group is improved as compared with that of conventional capacitors C, D, E. The electrical characteristics are enhanced remarkably in this manner because, when the compound containing the epoxy group is contained inside the capacitor element, impurities in air holes, decomposed substances, decomposed gases or the like generated by applying a voltage are captured by the epoxy group and the electrical characteristics are stabilized. Thereby, it is possible to obtain the capacitor whose change in the electrical characteristics with the passage of time is small.

IPC: H02M3/335
Filed: 1978-03-15
Abstract: PURPOSE: To control the collector current peak value of an output transistor and relax its usage conditions by integrating the rise of power voltage through an integrated circuit at start and shortening the continuity period of the output transistor.  
     CONSTITUTION: After the square wave signal from an oscillator circuit is inverted through a buffer circuit and its output voltage is wave-shaped, the output transistor switching-operates and the square wave AC voltage is generated. The start input power voltage is integrated through an integrated circuit consisting of the resistor R 11  and the capacitor C 4  to convert the AC voltage into the DC one and supply it to load. The continuity period of the output transistor Q 4  is shortened and the output peak value is controlled. This prevents the saturation of a converter transformer and relaxes the usage conditions of the output transistor.

Abstract: PURPOSE:To improve an antenna gain of a precise measurement system by providing a coarse measurement system and the precise measurement system having plural narrow beams, among which a most sensitive beam is selected according to information detected in the coarse measurement system. CONSTITUTION:The outline direction of a wave received from a specified direction is obtained by the coarse measurement system 9. The outline direction is aligned with the specified direction by the precise measurement system 10 having a driving system 5a according to a direction indication received from an indication control part 8. A reflection mirror 1a larger than that of the coarse measurement system 9 is used for element antennas 11 of the precise measurement system 10, so the beam width is narrow as compared with that of the coarse measurement system 9. The beam width is made to be covered by changing over the all antennas 11, and the information with a largest receiving electric power which is obtained by changing over the antennas 11 in turn is outputted to a signal processor 7a. A real direction is calculated by the indication control part 8 so as to be able to receive with the beam around the center having a best efficiency, then a peak of the beam is aligned with that direction. Thus, the sensitivity is high for the precise measurement system 10 because its antenna gain is larger than that of the coarse measurement system 9, and the angle measuring accuracy is also high due to the receiving direction is calculated with the comparison of oscillation amplitudes by the narrow beam.
