Title: Signal strength detector
Inventor: KANEKI KAZUO
IPC: H03G9/28
Filed: 1999-06-21
Abstract: PROBLEM TO BE SOLVED: To accurately detect strength of a received signal by using a current source, having a temperature characteristic different from that of another current source for biasing an amplifier section, thereby biasing a detection section. SOLUTION: Output from an amplitude detection section 21 is practically unchanged, even when an absolute temperature is subjected to change so long as the strength of a received signal is constant. When using a constant current source without temperature dependence for a current source 40 to bias the amplitude detection section 21, a collector current Ic outputted from differential amplifiers 23-25 is unchanged, even if the absolute temperature changes as long as the strength of the received signal remains constant.  Since a constant current source, whose characteristic is proportional to the absolute temperature T, is used for a current source 12 biasing a logarithmic amplifier section 1 and a constant current source whose characteristic is not proportional to the absolute temperature T is used for the current source 40 biasing the amplitude detection section 21, the detector is immune to the temperature change.

Abstract: PURPOSE: To obtain a semiconductor device which prevents a threshold voltage from becoming not matched by a method wherein gate electrodes of a pair of differential transistors are connected electrically by a conductor for charging-up prevention up to the halfway part of their manufacture. CONSTITUTION: The gate of a first transistor M1 and the gate of a second transistor M2 are connected electrically to each other by polysilicon 12 as an interconnection for charging-up prevention up to the stage of a prescribed production process. Then, by using the polysilicon 12 as the interconnection for charging-up prevention, a passivation film 14 is etched selectively, and the interconnection 12 for charging-up prevention is etched selectively. As a result, when the gates of the first and second transistors M1, M2 are formed, it is possible to restrain the deviation of the threshold voltage of the transistors as a pair from being generated by the influence of a charging-up operation which is subjected in a manufacturing process in which the passivation film 14 is etched.

Title: Ion plating device
Inventor: OTANI TADAYOSHI
IPC: C23C14/32
Filed: 1992-07-01
Abstract: PURPOSE:To provide the ion plating device having the excellent efficiency of utilizing the electrons from a plasma electron gun. CONSTITUTION:The electron beams generated from the plasma electron gun 9 are introduced from an electron beam exit port E into a chamber 1. While the electron beams introduced into a guide pipe 26 are reflected by the inside surface of the guide pipe 26, the electron beams progress until most of the electron beams are introduced into a funnel shape member 25 from lower side part of the funnel shape member 25. On the other hand, the material 3 in a crucible 2 is evaporated by the irradiation with the electrons from a filament 4 and the evaporated particles thereof are introduced from the lower small- diameter part of the funnel shape member 25 into the member. Consequently, the electron beams and the evaporated particles collide efficiently against each other within the funnel member and the ionization of the particles is accelerated.

Title: Seal device
Inventor: TAKAMATSU HIROSHI
IPC: F16J15/10
Filed: 1995-06-16
Abstract: PURPOSE: To facilitate the installation of a seal material and rotate each material easily even when each member is rotated after the seal material is installed by deflecting in close-fitting direction a seal top end part on the surface of one or the other member by the pressure of fluid invading between the members. CONSTITUTION: The top end part of a fin part 14 of a seal ring 1 is touched merely with the outer surface of a pipe main body 2 and, therefore, pressurization is not necessary for installation as in O-rings. As a result, the seal ring 7 can be installed easily. Also, after the seal ring 7 is installed, a joint fitting 3 can be rotated easily in circumferential direction. Also, when fluid invades between the outer surface of the pipe main body 2 and the inner surface of the joint fitting 3, the top end part of the fin part 14 of the seal ring 7 is formed in a shape pressed by its static pressure. Thus the seal ring is fitted more closely onto the outer surface of the pipe main body 2, and provides excellent watertightess or airtightness for prevention of leakage to the outside.

At this time, water enters through water inlet hole (1e), pushes down a piston (1b), and compresses the air in an air chamber (1a). The deeper it is submerged, the more water pressure is increased, at last the lower end (1f) of the piston (1b) is reached to the bottom of the air chamber (1a), and the whole air is entered into a compressed air vessel (1c) for recovery. Because the vessel (1c) is provided with a check valve, the air does not flow backward even at lowering of the air pressure in the air chamber (1a).
