Title: Resin sealing system for semiconductor
Inventor: NAGASAWA MASATO
IPC: H01L21/56
Filed: 1993-09-27
Abstract: PURPOSE:To inject resin constantly under a set pressure by injecting resin while taking account of the frictional resistance under idling. CONSTITUTION:Frictional force occurring between a pot 2 and a plunger 4 is measured by means of a pressure detector 7 when the plunger 4 is idling. When the plunger 4 pushes up a resin 3 and injects the resin 3 through a cull runner 6, the injection pressure is set equal to the frictional resistance plus a set injection pressure. Consequently, the resin can be injected under a constant pressure regardless of the frictional resistance between the pot 2 and the plunger 4. When the pot 2 and the plunger 4 are abraded and the residual resin causes to increase the frictional resistance thus equalizing the sum of the frictional force and the set injection pressure to the output of a driving source 5, the pot 2 and the plunger 4 are replaced.

Abstract: PURPOSE:To execute the stable identifying action to the noise by making the comparator output set by dislocating the reference voltage to the extend of several %-10% of the data equivalent waveform amplitude from the input voltage of the comparator at the time of no signal into the signal for the timing circuit. CONSTITUTION:From a reference voltage input terminal 107 to a comparator 102, a reference voltage Vref2 dislocated to the extent of several %-10% of a data equivalent waveform amplitude from the input voltage of the comparator 102 at the time of no signal namely, the input voltage of an input terminal 105 at the time of the no signal, is given.
