Title: Treatment of metallic material used as sample of microscope
Inventor: ITOU HITOMI
IPC: G01N1/36
Filed: 1980-02-21
Abstract: PURPOSE:To prevent the surface of a sample from contamination which is caused by aqueous vapor and enable to observe the tissue of sample sufficiently by exposing metallic materials for samples to paraffinic vapor inside a vacuum vessel to fill the holes and molded detects of samples with paraffine. CONSTITUTION:Chip 6 to be tested is buried in epoxide resin 7 to make up sample 1 so that it can be easily polished and, after polishing the observing surface, the sample is set up on the inside of vacuum vessel 2, which is evacuated with vacuum pump 3. Current supply to heat generating member 5 which is set up on vacuum vessel 2 and buried in paraffine 4 causes paraffinic vapor to evporate on sample 1. Thus, holes are filled with paraffine, the sample is prevented from the infiltration of an etching solution and the surface of sample is also prevented from pollution cauded by vapor generated from the etching solution, making it possible to observe the tissue sufficiently and obtain clear pictures.

Title: Automatic gain adjusting device for hearing aid
Inventor: ISHIDA HIDEAKI
IPC: H03G3/20
Filed: 1983-02-09
Abstract: PURPOSE:To improve the elimination of noise and the articulation by connecting a coupling capacitor being a high impedance to a low sound frequency in parallel with an F.E.T. so as to suppress the low sound frequency having lots of noise components. CONSTITUTION:When a sound pressure of small - medium level is inputted to a microphone 11, since a gate DC voltage of the F.E.T. 12 proportional to the output level of an amplifier 14 is low, the impedance between the source and drain of the F.E.T. 12 is low and no effect is given on an output sound pressure of a receiver 15. If an excessive input sound pressure is given to the microphone 11, the impedance between the source and drain of the F.E.T. 12 is increased by the gate DC voltage of the F.E.T. 12 proportional to the output level of the amplifier 14 and the output sound pressure of the receiver 15 is suppressed at frequencies <=500Hz by the compression effect of the F.E.T. 12. But the frequency components >=500Hz are bypassed toward the coupling capacitor 22, then a large output sound pressure is obtained.

An N<-> type epitaxial layer 22 remains without enhancing its concentration in the N P N transistor 27 of a peripheral circuit S except a memory cell M. Thus, the resistivity of the region 22a is low, the base parasitic resistance 26 of the P N P transistor 1 of the cell M is reduced, and saturation of the N P N transistor 3 associated with the transistor 1 and an inverter at the time of reading is decreased. Accordingly, the writing time of this semiconductor memory is shortened.
