摘要:
When a silicone gel is injected into a case, since the gel is liquid before curing, the gel attempts to rise along a minute gap formed between a front face of a first electrode and a rear face of a resin member due to capillary action. However, since the gap becomes larger at a cavity in the first electrode, the rising motion of the gel stops at the level of the cavity. More specifically, the gel is prevented from reaching portions of the first electrode and a second electrode for connection with external terminals. Further, since the rising motion of the gel can be prevented by the cavity, the first electrode and the second electrode can be arranged in a close relationship with each other.

In a semiconductor apparatus in which a main current of a semiconductor device flows through a wiring pattern formed on an insulation circuit board, the rise in temperature of the wiring pattern is suppressed and the increase in cost of parts can be minimized. On the insulation circuit board, a copper pattern is formed. A heat spreader is soldered to the copper pattern, and the heat spreader is loaded with a semiconductor chip. An external electrode and the heat spreader are arranged to shorten the distance between the side of the external electrode and the side of the heat spreader.

There is provided a process for feeding in a recorder a recording medium having a glossy surface from a tray in which the recording media is loaded and piled up, in which the last sheet of the recording medium can be fed smoothly without adsorption to the tray. An extra sheet is laid between the tray and the recording media in order to prevent the adsorption of the last recording medium to the tray and to ensure that the last sheet of the recording medium is also led out smoothly from the tray.

C., and the rate of increase of the viscosity of the adhesive being in the range of 1.5 to 8 times when the temperature of adhesive is dropped from 85.degree. to 30.degree. C.,(c) the adhesive, of which temperature is 60.degree. to 95.degree. C., being applied onto the flute tips of corrugated medium to manufacture corrugated board,and an aqueous adhesive therefor. The process for production of a corrugated board has excellent effect on heat energy saving characterized in that said corrugated board can be manufactured at high speed without heating after application of the water-base adhesive at a temperature of 60.degree.-95.degree. C., and the adhesive is easy to handle and has improved adhesion property.
