Title: Automatic assembling machine for semiconductor device
Inventor: SHIMATA TSUTOMU
IPC: H01L21/50
Filed: 1978-05-24
Abstract: PURPOSE: To improve the reliability of products by shortening assembling time while removing a temperature cycle, by constituting a pellet junction part and a wire junction part both by the same machine.  
     CONSTITUTION: Lead frame 7, contained in a case by loader part 1, is supplied to horizontal shoot by several pawls, which carries it horizontally and intermittently, and then carried in sequence. At junction part 2, a collet with adsorption-held semiconductor pellet 9 moves and the pellet is thermally pressure-welded to a carried frame. A wire is taken out from a capillary which can move horizontally and vertically and fused into pieces and the frame carried by shoot 21 is connected 3 to  the pellet by the wire. The pellet conection mechanism and wire connection mechanism, mounted on the common frame carrier mechanism, interlock together and  also control the temperature of the heat block so that the temperature of the pellet  and lead frame will change smoothly between both processes. Lastly, it is lifted  by shoot 80 to unloader part 4. Consequently, no cracking occurs to a semiconductor and characteristics of parts never deteriorate.

IPC: B60S1/34
Filed: 1984-03-30
Abstract: PURPOSE:To prevent early deterioration at the rubber portion in wiper blade and to limit rattling of wiper blade by securing the wiper blade while contacting lightly against the window panel face. CONSTITUTION:When travelling without using the wiper, the stopper section of retainer 3 is contacted through a spring 7 against first stopper wall 23 and engaged. Consequently, the retainer 3 is set at the first lift position to secure the wiper blade while contacting lightly against the window panel face. Here, the compressive deformation at the rubber portion of wiper blade is temporarily released and even if predetermined wind pressure is applied onto the wiper blade under travelling, the wiper blade is never contact strongly against the window panel face.

Title: Device for separating oxygen from air electrochemically
Inventor: FUJITA YUUKOU
IPC: C25B9/17
Filed: 1980-05-09
Abstract: PURPOSE:To prevent excessive dilution of electrolyte concn. on account of mutual diffusion of water and electrolyte by interposing an airtight weir vessel connecting an electrolytic cell and a makeup water tank and transferring the makeup water to the electrolytic cell side only when the level of the electrolyte lowers. CONSTITUTION:An airtight weir vessel 3 is installed between an electrolytic cell 1 which electrochemically separates oxygen from air and a makeup water tank 2. When disoxidation operation is accomplished in the cell 1, the water content in the electrolyte 6 evaporates and the level of the electrolyte 6 lowers. As the liquid level lowers, the level of the electrolyte 6' in the vessel 3 also lowers to evacuate a space part 12, then the water 13 in the tank 2 forces upward the water 13' in the vessel 3. This water flows over a weir 14 and shifts into the electrode 6' side. Then, the level of the electrolyte 6 returns again to the original position. The decrease in electrolyte concn. is effectively prevented by this mechanism.
