Abstract: A wiring pattern forming method in which side etch of a wiring pattern at the time of etching the substrate copper foil of a copper plating pattern is reduced to hold down an increase in line resistance, the wiring pattern forming method including the steps of: providing a plating resist pattern of which open area comprises a wiring pattern on the surface of a copper-clad laminate which is obtained by providing a copper foil on an insulating substrate; plating such open area with copper to form a copper plating pattern; then plating a crevice between the copper plating pattern and the plating resist pattern with a solder film by alternately repeating application of a current for a predetermined time period and suspension of the current application for a predetermined time period; and etching away the copper foil by using the solder film as an etching resist to form the wiring pattern.

Abstract: The invention relates to a facial suction device for massaging facial skin and the like by suction, and its object is to controll suction force appropriately and operation noise small.The suction device according to the invention includes a suction pump comprising a diaphragm 9 of which the center part is formed in a dome section 11, a suction valve 13a and an exhaust valve 13b both made of thin plate and disposed on the end of the diaphragm. And the dome section 11 of said diaphragm 9 is expanded and contracted by the rotation of an eccentric shaft of a motor 4, thereby the suction valve 13a and the exhaust valve 13b are operated to conduct sucking against the face.

Abstract: A floppy disc apparatus has a single printed wiring board mounting thereon a control circuit section including therein an overall control circuit and write circuit section, a head switching circuit and reproduction circuit section, and a motor drive circuit section. The motor drive circuit section is disposed in opposite relation to the overall control circuit and write circuit section and the head switching circuit and reprodcution circuit section with the drive motor therebetween. The overall control circuit and write circuit section and the head switching circuit and reproduction circuit section are disposed in successive relation with the head switching circuit and reproduction circuit section disposed adjacent to a connector for connecting lead wires of a head mechanism.

Abstract: A picture information retrieval system in which each time an initial position detecting mark provided in correspondence with the first picture on an information recording medium for detecting the first picture passes the initial position during the retrieval operation the content of the counting section is corrected.
