Title: Chip-type capacitor
IPC: H01G9/08
Filed: 1992-03-18
Abstract: PURPOSE:To improve humidity resistance, life and stability and to enable thinning by improving armor of a chip-type capacitor. CONSTITUTION:A solid-state capacitor is covered with an insulating resin film 2 to keep insulation properties between a metallic foil 3 which is an outermost armor and a capacitor 1. It is further covered with the metallic coil 3; thereby, humidity resistance and stability are improved and a chip-type capacitor is thinned by using such an armor. One or both of end parts of the resin film 2 and the metallic foil 3 are deviated and the resin film 2 is exposed outside a metallic plate end part in an anode side or a cathode side or both thereof; thereby, it is possible to omit a masking process, to improve operativity, and to reduce a cost. Thermal resistance, dimensional accuracy, etc., can be also improved.

IPC: B41J29/10
Filed: 1984-03-30
Abstract: PURPOSE:To reduce noise generated by a printer and enable to reduce cost and size, by providing a resonance-type sound-absorbing mechanism in a gap between a casing and a frame of the printer. CONSTITUTION:A resonance sound-absorbing box is provided between the frame 2 and a lower casing 1, and the frame 2 is provided with a multiplicity of holes 3 in a checker-board pattern, whereby noises are led into the box. In this case, when the resonance frequency is made to accord with the frequency of the noise, the noise is markedly reduced. Although the holes are circular in shape in the figure, they may have other shapes, and may be slits. Accordingly, since a part of the frame and the casing can be utilized, the cost can be reduced, and since the sound-absorbing mechanism is provided by utilizing a needless space in the printer, no trouble arises in reducing the size of the printer.

Filed: 1990-03-12
Abstract: PURPOSE:To impart a revolving stream to a liquid by reduced centrifugal effect by mounting a drum and a vibration generator both of which are supported elastically, a conical cylinder having a liquid supply port and a solid discharge port formed thereto and a filter member. CONSTITUTION:When vibration generators 25a, 25b are synchronously operated, a drum 24 and a filter cylinder 29 are subjected to circular oscillation. When a liquid is supplied from a liquid supply port 27 in this state, the liquid receives the circular oscillation of the drum 24 and the filter cylinder 29 to generate a revolving stream. A solid is pushed toward the inner wall of the drum 24 to be accumulated and discharged from a discharge port 28 as granulated lumps. The separated liquid passes through the surface pores 38 of the filter cylinder 29 to be discharged to the outside through a hollow shaft 30. The fine particulate solid on the surface of the filter cylinder 29 is pushed toward the inner wall of the drum 24 to be discharged to the outside as aggregated lumps. By this constitution, this separator can be operated by reduced centrifugal effect and the loss of mechanical energy can be reduced.
