IPC: H01L21/52
Filed: 1988-03-31
Abstract: PURPOSE:To enable a semiconductor chip to be solder mounted desirably, by providing a metal having good wettability by solder on the surface of a base, and providing a frame of a metal having no wettability by the solder on the surface so as to surround a region where a chip component is to be mounted. CONSTITUTION:A solder piece of gold-tin alloy is put in a region surrounded by a frame 5 and is molten by heating the same within atmosphere of inert gas. At the same time, a semiconductor chip 2 put on the solder is pressed against the solder so as to be secured on a copper base 1 through the solder 6. The molten solder 6 having wetting properties to a metal 4 tends to extend around, but such tendency is limited by the frame 5 having no wettability by the solder 6. Accordingly, a sufficient thickness of the solder 6 can be ensured for securing the semiconductor chip 2 rigidly.

Title: Forced-air cooling type transformer
Inventor: SUZEKI TOMOO
IPC: H01F27/12
Filed: 1982-05-08
Abstract: PURPOSE:To effect an efficient control without impairing the life of a motor of each of an oil feeding pump and a cooling fan, by controlling the frequency of an auxiliary power source by means of a device which can vary frequency, such as an inverter or the like. CONSTITUTION:An auxiliary power source 1 is connected to an inverter 2 through a changeover switch 6. When the transformer is used in a region where both the load and the frequency are high, for example, when the load is not less than 90%, the changeover switch 6 is changed over so that an oil feeding pump 3 and a cooling fan 4 are directly connected to the power source 1. On the other hand, when the load is less that 90%, the power source 1 is connected to the inverter 2 through the changeover switch 6 in order to control the number of revolutions of the motor of each of the oil feeding pump 3 and the cooling fan 4 through the change in frequency. When the transformer is used in a region where both the load and the frequency are low, since the motor current is also low, there is no problem of the effect of the inverter pulsating pulse on the motors of the oil feeding pump and the cooling fan.

Abstract: PURPOSE:To perform the store instruction processing at a high speed even in such a case where a storing destination has no hit to a cache memory by avoiding the waiting state of a microinstruction regardless of a cache hit with storage of addresses in the same page. CONSTITUTION:A page boundary detecting circuit 116 decides whether a write address is stored or not in a page different from that of the preceding address in case an executing instruction shows a write command. A flip-flop 113 is set when the different pages are detected between said two addresses. An execution clock control part 114 interrupts the execution of an instruction in response to the set output of the flip-flop 13. Then the waiting state is avoided for a microinstruction regardless of a cache hit with storage of addresses in the same page. Thus a store instruction is processed at a high speed in a simple constitution even in such a case where a storing destination has no hit to a cache memory.
