Title: Anodic foil for electrolytic capacitor and manufacture thereof
Inventor: SUZUKI KAZUHIKO
IPC: H01G9/07
Filed: 1995-02-03
Abstract: PURPOSE: To reduce a leakage current, and to improve withstand voltage property by forming an aluminum oxide layer on the surface of an aluminum foil through formation treatment and evaporating a silicon oxide layer to a specified thickness on the aluminum oxide layer. CONSTITUTION: The surface of an aluminum foil having a purity of 99.99% is roughened to 0.5-20μmRmax through etching treatment, and formation treatment is performed. SiO films are deposited under a vacuum on both surfaces of the aluminum foil to a film thickness of 0.002-0.1μm. The aluminum foil, to which evaporation is completed, may also be used as an anodic foil for an electrolytic capacitor as it is, but the aluminum foil, on which a silicon oxide layer is formed, is formation-treated again for improving insulating characteristics. Accordingly, a leakage current is reduced and withstand voltage property can be enhanced.

Filed: 1990-01-26
Abstract: PURPOSE:To provide a necessary sufficient vibration reducing effect over a wide range by mounting a mass member through an auxiliary elastic body on a propeller shaft having both ends coupled with a mating side rotary member through a rubber system elastic body. CONSTITUTION:A ring-like mass member 7 is coupled integrally with the outer peripheral of the central portion of a propeller shaft 1 through a rubber system auxiliary elastic body 6. The weight of the mass member 7 and the spring constant of the auxiliary elastic body 6 are respectively set such that the natural frequency of the auxiliary vibration system determined by the auxiliary elastic body 6 functioning as a spring and the mass member 7 coincides with the natural frequency of a main vibration system having the propeller shaft 1 itself as a mass and the rubber system elastic bodies 2, 4 as springs. Thus, when the natural frequency of the auxiliary vibration system for example is set to the characteristic value of bending vibration of the main vibration system, a peak of torque transmission rate appears before and after the resonance frequency, while the peak value itself is lower than prior one and the transmission rate is substantially lower than prior one near the resonance frequency so that a vibration reducing effect can be obtained in a wider region.

Filed: 1984-02-01
Abstract: PURPOSE:To allow a device to be used for two-system broadcast reception by providing a D type flip-flop and a mode switching terminal compensating the reset signal pulse width and switching only the potential level of one terminal. CONSTITUTION:When the electric potential A17 of a mode switching terminal 17 is a logic level 0, an output potential of an NAND gate 20 is a logic level 1 in spite of an output of a T type flip-flop FF18 and an output of a reset signal generator circuit 19. When the potential A17 of the terminal 17 is a logic level 1, the output potential C19 of a circuit 19 is inverted and outputted at an output potential D20 only when an output potential B18 of an FF 18 is in a logical level 1, further the output potential becomes E21 with one clock delay from a D type flip-flop 21. Therefore the output potential of the gate 22 becomes J22 and inverts the output potentials of the T type FF18 to reset a dividing circuit 2. In this way, the device can be used for two-system broadcast reception.

Filed: 1993-01-11
Abstract: PURPOSE:To enable the inspection of the overall length of a CV cable by performing a totalization processing of a two-dimensional image in a direction of movement of a defect to improve a detection limit and an inspection speed of the defect. CONSTITUTION:X rays irradiated from an X ray source 1 are transmitted through a CV cable 2, enters an X-ray intensifier 3 to be converted to electron and outputted as light after amplifier. The image of the cable is taken with a CCD camera 4. Photographing with the camera 4 requires about 1/30sec at a time and the cable 2 moves on a production line. When a metal foreign matter (defect) exists in an insulating body, the foreign matter moves between the photographings and the image of the cable is formed being extended in the direction of movement of the metal foreign matters. So, a 1-line delay circuit is inserted before line adders of an image processor 5. This enables the shortening of the extension of the image to obtain a data almost the same as that in the photographing at rest requiring 1/30sec thereby achieving the upgrading of an inspection speed and S/N in the inspection of the overall length of the cable 2.
