Filed: 1995-05-24
Abstract: PURPOSE: To enhance the heat dissipation performance by interposing a chamber between an axial fan and heat dissipation fins, passing the cooling air through a predetermined opening in the chamber and discharging the cooling air to the heat dissipation fins thereby cooling the heat dissipation fins uniformly. CONSTITUTION: A heat sink 14 is provided with a large number of pins having rectangular cross-section on the surface of a board 16 and an LSI package 18, containing a heating element, is bonded tightly to the rear surface of the heat sink board 16 in the center thereof. A chamber 19 is bonded tightly to the heat sink 14 with an opening 21, having area equal to or smaller than that of the board 16, touching the upper part of fins. Cooling air is fed through an opening 22 into the chamber 19 by means of an axial fan 11 and flows through the opening 21 into the heat sink 14 thence passes between the heat dissipation fins 15 before blowing to the outside of heat sink. Since the cooling air is fed uniformly to the heat dissipation fins from the axial fan 11, cooling performance of heat dissipation pin directly under a motor can be prevented from lowering.

Title: Image retaining member
Inventor: FUJIMURA NAOTO
IPC: G03G5/02
Filed: 1979-09-28
Abstract: PURPOSE: To enhance various characteristics such as charge (image) retentivity, suitability to easy removal of residual charges by pressurization and toner image transfer efficiency of an electrostatic or toner image retaining member by forming a surface layer made of pressure-sensitive electrically-conductive rubber on the surface of the member.  
     CONSTITUTION: A pressure-sensitive electrically-conductive rubber sheet prepared by dispersing electrically conductive particles of Al, carbon or the like in a rubbery matrix such as silicone rubber or butadiene rubber is adhered to the surface of the image retaining member of an electrophotographic receptor or the like optionally having a photoconductive layer. The resulting surface layer usually has insulating properties and superior charge retentivity, yet when it is pressurized, the resistance is decreased and surface charges disappear rapidly. Accordingly, pressurization increases the toner image transfer efficiency and enhances the cleanability. In addition, the surface layer enhances the mechanical strength and protects the photoconductive layer. Thus, corona discharge or the like is not required for the secondary discharge and transfer charge, and the apparatus is simplified.

Title: Lead frame for semiconductor device
Inventor: MIKI SHINICHI
IPC: H01L21/56
Filed: 1983-07-11
Abstract: PURPOSE:To obtain a stable workability with low cost by covering a plurality of die bonded regions, a plurality of wire bonded regions and the front and back surfaces of a plurality of the first and second leads with noble metal plating layers. CONSTITUTION:Silver plating layers are formed only on die bonded portions 10, wire bonded portions 14 and tie bar portions 15 and lead wirings 17 of necessary portions as a semiconductor device. When thus partly silver-plated, the silver amount is reduced, thereby supplying an inexpensive lead frame. In resin sealing, since a silver plating layer is not present on the lead frame of the air vent portion of a sealing mold, a suitable air gap of the air vent portion can be readily held, and externally pushing effect for air bubbles in the cavity can be obtained. Since the leads 17 are contacted with the mold, the silver and the resin can be readily separated since the silver and the resin has wrong contacting property. As the silver plating is executed on the entire lead wirings, preferable solderability and corrosion resistance can be obtained even if surface treatment is not performed in the next step, thereby reducing the cost, stabilizing the produciton and improving the quality.
