Title: Method for precisely working on compound semiconductor
Inventor: KADOYA YUTAKA
IPC: H01L21/26
Filed: 1991-12-24
Abstract: PURPOSE:To provide a method for precisely working on compound semiconductor substrates by which the surface contamination of semiconductors by impurities can be reduced. CONSTITUTION:A thin film containing at least indium or indium arsenide or indium-gallium arsenide thin film 1 is used and a compound semiconductor substrate 3 coated with the thin film 1 as the outermost film is irradiated with an electron beam EB in the first process (b). Then the part other than that irradiated with the beam EB is selectively etched off in the second process (b). Since the film 1 can be deposited by, for example, the molecular beam epitaxial growth method and continuously deposited by using a device used for forming the working layer 2 of a field effect transistor or laser element, the film 1 can be formed without contaminating the surface of the semiconductor with impurities. Therefore, samples can be directly transferred to an electron beam irradiation system from a molecular beam epitaxial growth system and the surface contamination of substrates with impurities can be remarkably reduced.

Title: Noise eliminating circuit
Inventor: IIJIMA TAKASHI
IPC: H04H40/72
Filed: 1995-12-28
Abstract: PROBLEM TO BE SOLVED: To prevent malfunction in noise elimination due to a sub-channel signal at changeover by detecting a control channel signal so as to make the sensitivity of the noise elimination circuit less sensitive in the case of changeover from a monaural broadcast into a stereo broadcast or a dual broadcast. SOLUTION: In the case of changeover from a monaural broadcast into a stereo broadcast or a dual broadcast, a drive circuit 18 generates an output signal of an L level to a light emitting diode 19 to drive it. An attenuation control circuit 21 generates an attenuation control signal with a prescribed width in response to an output signal of an L level and the attenuation of an attenuation circuit 7 is increased depending on the output signal in response to the attenuation control signal so as to make noise detection sensitivity less sensitive. Thus, an output signal from the attenuation circuit 7 is lower in the voltage than a reference voltage of a trigger generating circuit and no trigger is generated from the trigger generating circuit 6. Since a noise elimination section 21 does not make noise elimination, a signal waveform of a voice multiplex signal is not deformed.  Thus, noise elimination is not conducted for a prescribed period.

Filed: 1991-10-25
Abstract: PURPOSE:To improve production efficiency by enhancing the heat transfer efficiency and consequently shortening the time required for hardening resin material by a method wherein the interior of a forming mold is divided into a plurality of chambers so as to form a channel, by which hot water circulates all over the respective chambers by means of reinforcing and flow-straightening ribs provided in the respective chambers. CONSTITUTION:In the upper side 10 for forming resin, a chamber, through which hot water is circulated, is provided and divided into eight chambers A-H, for example, as a whole. Ribs 11, which serve both for flow straightening and for reinforcing in combination, are provided in the respective chambers A-H so as to form a channel 12, by which hot water circulates all over the respective chambers A-H, with the ribs 11 in the respective chambers A-H. Thus, heat is uniformly transferred from the hot water running through the respective chambers to forming surface, resulting in uniformly heating resin material. In addition, since enough reinforcement is obtained by providing the ribs, the thickness of the forming mold can be made thinner. Further, since heating is performed from the interior of the mold by hot water, the heat conduction to the mold becomes extremely good, resulting in allowing to reduce the time required for thermally hardening the resin material.
