Title: Semiconductor device
Inventor: HASEGAWA KAZUYOSHI
IPC: H01S5/00
Filed: 1990-01-22
Abstract: PURPOSE:To enable a partial pressure of H2O which is included within a sealing gas to be reduced and obtain a semiconductor device where a dew point temperature is reduced by reducing an inner space within the semiconductor device with the inner space including a semiconductor active element to 1 atmospheric pressure or lower. CONSTITUTION:In a semiconductor device with an inner space including a semiconductor active element, the inner space of the above semiconductor device is reduced to 1 atmospheric pressure or lower. For example, the relationship between H2O volume content and dew point temperature within a cap when the inner space pressure is set to 1.0, 5.0 and 0.1 atmospheric pressure is as shown in the graph. Namely, as the inner space pressure within the semiconductor device is reduced, the dew point temperature with the same H2O volume content is reduced. Thus, by reducing the pressure within the inner space including the semiconductor active element to 1 atmospheric pressure or lower, the inner space dew point temperature is reduced, temperature inducing migration, etc., is reduced, and a highly reliable semiconductor device can be obtained.

Title: Meter driving circuit
Inventor: KOBAYASHI HIROYUKI
IPC: G01R19/00
Filed: 1978-02-09
Abstract: PURPOSE: To enable meter driving to be performed even with minute signals by letting meter-driving transistors make class "B" operation.  
     CONSTITUTION: Since the minute signal supplied to input terminal 12 is applied with negative feedback via transistor Q 3 , feedback resistances R 5 , R 6  from the output part of a differential amplifier circuit 11, it is differentially amplified by the gain of R 5 /R 6  and is supplied to driving TrQ 5 , Q 6  sides. On the other hand, there is a voltage of 3VF between the base of TrQ 4  and the base of TrQ 5  because level shift is being accomplished in diode D 1  thru D 3  parts and therefore there is a voltage for VF component between the emitter of TrQ 4  and the emitter of Q 5 . This VF is a diode forward voltage. Hence, by making the values of the resistances R 10 , R 11  equal, the bias of the approximately VF component is applied to the base of TrQ 6  and therefore TrQ 6  makes class "B" operation.
