Inventor: ENOMOTO HIDEO
IPC: C02F1/46
Filed: 1985-08-29
Abstract: PURPOSE:To efficiently remove the metallic salt in a chemical liquid by taking the chemical liquid used for the surface treatment of a metal out of a housing tank and selectively concentrating the metallic salt in the chemical liquid, then electrolytically depositing the concd. liquid with a diaphragm electrode. CONSTITUTION:The chemical liquid is taken out of the housing tank 1 and after the metallic salt in the chemical liquid is selectively concentrated by a metallic ion concentrating means 3 such as a filter method, the foregoing concd. liquid is electrolyzed by an electrolytic cell 2 consisting of a cathode 16, an anode 18 and a diaphragm 17 to deposit the metallic-component on the surface of the cathode 18 in the stage of removing the metallic salt in the chemical liquid. As a result, the metallic salt in the chemical liquid used for the surface treatment of the metal is efficiently removed and the amt. of the chemical to be used is considerably economized without the problem of waste water treatment.

Title: Chucking device for die-bonding semiconductor pellet
Inventor: UESUGI KENJI
IPC: H01L21/677
Filed: 1984-09-11
Abstract: PURPOSE:To prevent the protective film of a semiconductor pellet from being damaged as well as to prevent any miss in attraction of the pellet from generating by a method wherein the collet is constituted of an elastic resin material, and at the same time, the chucking surface of the collet is formed into a fine continuously roughened roughness surface. CONSTITUTION:A collet 3 is a block-type member consisting of an elastic resin material and the lower end surface thereof is flatly formed as a chucking surface 4 to support the surface on one side of a semiconductor pellet 1. At least a part 10 of this chucking surface 4, which comes into contact with the surface 9 to be attracted of the pellet 1, is formed into a fine continuously roughened roughness surface. In the surface 4 formed in such the way, when the pellet 1 is attracted on the surface 4 by being evacuated, the fine roughness surface is flatly deformed. Accordingly, the surface 9 and the surface 4 are in close contact with each other at the time of the attraction. Moreover, when the evacuation is released, the surface 4 is restored to the roughness surface by the surfaces own elastic force and numerous gap parts (g) are generated between the surface 4 and the surface 9. As a result, the pellet 1 is made to disengage from the surface 4.

IPC: F16H61/08
Filed: 1987-07-30
Abstract: PURPOSE:To suppress lag of actuation of a friction engagement element by changing the control characteristic in supply control of the working oil pressure for the friction engagement element in accordance with the sensed temp. of working oil, or a temp. associate therewith. CONSTITUTION:In a hydraulic control device for an automatic transmission, a control characteristic changing means changes the control characteristic of a hydraulic control means in supply control of the working oil pressure for a friction engagement element such as clutch, brake, etc., in a speed change mechanism in accordance with the temp. of working oil sensed by an oil temp. sensing means, or a temp. associate therewith. Thereby the working oil pressure supplied to the friction engagement element is changed with a control characteristic according to the temp. of working oil, i.e. viscosity, which will eliminate lag in actuation of the friction engagement element at, for ex., a low temp. to lead to obtainment of proper engaging timing etc. Thus occurrence of large speed change shock can be prevented, and durability of the friction engagement element be enhanced.

Filed: 1981-11-28
Abstract: PURPOSE: To exclude a coupling capacitor at an input part and facilitate the formation of an IC, by connecting a current mirror consisting of an NPN transistor to a PNP transistor to which a signal source is directly connected as well as another PNP transistor which is connected in series to the signal source.  
     CONSTITUTION: A signal source 1 is connected directly to the base of a PNP transistor (TR)3, and the emitter of the TR3 is connected to the collector of a PNPTR4. At the same time, the collector and the emitter of an NPNTR16 forming a current mirror circuit 15 are connected in parallel to the source 1, and the collector of a diode-connected NPNTR17 of the circuit 15 is connected to the base of the TR4. At the same time, the emitter of the TR17 is grounded. A power supply terminal 5 is connected to the TR4 and TR14 via a constant current circuit 7 and a resistance 13 to deliver the signal to an output terminal 10. In such constitution, the base current of the TR3 is absorbed by the TR16, and no DC current flows to the source 1. Thus a coupling capacitor can be excluded out of an input part.

Title: Antireflection film of optical parts made of synthetic resin
Inventor: GOSHO SHINICHIRO
IPC: G02B1/11
Filed: 1994-07-22
Abstract: PURPOSE:To provide an antireflection film which is formed of a three-layered structure on the surface of optical parts made of a synthetic resin and with which as-designed optical characteristics are obtainable by simple optical designing and environmental resistance is excellent. CONSTITUTION:This antireflection film is formed by depositing a chromium layer 2 having a film thickness <=15nm (ideally <=5nm) as a first layer, a cerium dioxide layer 3 as a second layer and a silicon dioxide layer 4 as a third layer on the surface of an acrylic substrate (optical parts) 1. Although the antireflection film is physically formed of the three-layered structure, the chromium layer 2 is extremely thinly formed and, therefore, the execution of the optical designing by taking only the refractive indices and layer thicknesses of the cerium dioxide layer 3 and the silicon dioxide layer 4 suffices. The as- designed stable optical characteristics (spectral reflectivity) is thus obtd. and the environmental resistance performance is improved by the excellent affinity and adhesion property of the chromium layer 2 to the acrylic resin substrate 1.

The distribution of the reflected light rays from the surface to be checked 6a in a focus control circuit 12 is detected. A distance between the optical system 1 and the test specimen 6 is kept constant. Then, a defect is detected by the comparison between the reflected light rays and a specified standard value in a comparator 16, and a signal is generated. The position and the size of the defect are detected with a defect processing circuit 17. The position of the optical system 1 is fixed with a focus locking circuit 29. Thereafter, the detected defect is scanned again with a crossfeed motor controller 27. The maximum value of the fluctuation in distribution of the reflected light rays from the surface to be checked 6a in the second scanning is detected with a peak holding circuit 31. Then, the height of the defect is computed by a personal computer 28 from the maximum value of the fluctuation.
