IPC: H05H1/46
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To provide a low cost and compact surface modifying treatment device using a plasma capable of generating high-voltage and high frequency discharge voltage by using a DC power source with relatively low output voltage. SOLUTION: In this surface modifying treatment device T1, discharge voltage for generating corona discharge is generated by superimposing pulse voltage on steady DC voltage.

Title: Phase difference plate and circularly polarizing plate
Inventor: YAMANAKA ATSUSHI
IPC: G02B5/30
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To obtain a phase difference plate which has decreased phase differences by wavelengths and has the excellent consistency thereof by sticking a quarter-wave plate and a halfwave plate to each other in the state of intersecting their respective optical axes. SOLUTION: This phase difference plate is formed by sticking the quarter- wave plate (a double refractive film of which the phase difference of the double refractive light is a quarter wave) 13 and the halfwave plate (a double refractive film of which the phase difference of the double refractive light is a half wave) 11 to each other in the state of intersecting the respective optical axes at a preset angle. The halfwave plate 11 and the quarter-wave plate 13 are formed by subjecting high-polymer films to stretching treatments. In such a case, a polycarbonate material which is often used as a wavelength material is selected. This phase difference plate is designed to function as the quarter-wave plate improved in the wavelength dispersion characteristic when linearly polarized light of a perpendicular direction (0 deg. direction) is made incident from the halfwave plate 11 side.  The phase difference plate is thus capable of converting the light to nearly perfectly circularly polarized light regardless of wavelengths in a range of visible light.

Title: Surface treatment of aluminum-containing compound semiconductor wafer
Inventor: TAKEUCHI RYOICHI
IPC: H01L21/308
Filed: 1985-10-14
Abstract: PURPOSE:To remove only a defective region on a wafer by etching by using a phosphoric acid water solution of mixing ratio 1:5-1:40 of phosphoric acid and water for the surface treatment of the wafer. CONSTITUTION:A wafer which has the abnormal growth region (the defective region) of crystal due to imperfect wiping off is dipped in a phosphoric acid water solution of mixing ratio 1:5-1:40 of phosphoric acid and water. The phosphoric acid water solution is effective for etching crystal which has high Al mixed crystal ratio and the speed of etching crystal which has low Al mixed crystal ratio is rather slow so only the defective region on the wafer is removed by etching.

Consequently, no current flow into the rolling bearing 3 comprising the outer ring 11 and the inner ring 12. Current flow into the rolling bearing 3 is also prevented by insulating the fixing part of the motor case 2 and the motor base through an insulating member. In any case, current does not flow into the rolling bearing 3 interposed between the rotary shaft 4 and the motor case 2 and thereby the rolling bearing 3 is protected against electrolytic corrosion.

Title: Automatic bank switching circuit for memory
Inventor: SAKAI HIROSHI
IPC: G06F12/06
Filed: 1993-09-14

Title: Pressure-sensitive conductive elastomer
Inventor: OKAMOTO TERUO
IPC: H01B5/16
Filed: 1989-09-04
Abstract: PURPOSE:To stabilize characteristics by dispersing conductive vitreous microspherical carbon grains each having a specific grain diameter in a non- conductive foamed elastomer having a specific foamed cell diameter. CONSTITUTION:An independent or continuous foamed body having each cell of 50 to 350mum in the size of each of foamed cells constructing a non-conductive foamed elastomer is preferably, whereas a foamed body having each cell of any size below 50mum has a small change in its pressure-resistance and a foamed body having each cell of any size over 350mum is unpractical because of reduction in its strength. Any value below 1mum in the diameter of each of conductive vitreous microspherical carbon grains being dispersed in the non-conductive foamed elastomer causes difficulty in manufacturing the grain while causing a small change in its resistance. Because a grain having any diameter exceeding 15mum causes a rough change in its resistance, a grain having diameter of 1mum to 15mum is preferable. Thus, a pressure-sensitive conductive elastomer can be manufactured with stable characteristics.

IPC: C22B21/06
Filed: 1993-09-14
Abstract: PURPOSE:To improve the collecting capacity of inclusion and to prevent flow-out of the collected inclusions by depositing needle crystal on the surface of a ceramic-made packing body. CONSTITUTION:For example, in a two-step treating apparatus arranged with two molten metal treating chambers, molten Al is introduced into the first treating chamber 3 and brought into contact with alumina balls 4 as filtrating material packed in the chamber 3 to collect the solid impurity (inclusion) in the molten Al. The molten Al passing through the chamber 3 is introduced to the second treating chamber 6 and treated by the same way. In this method, the alumina balls deposited and covered with needle crystals on their surface are used as the filtrating material. For example, after granulating alumina to a spheroidal shape, the alumina is sintered to form an alumina ball, and after dipping the alumina ball into a slurry solution of prescribed composition, the treated alumina ball is pulled up and the excess slurry is removed and the ball is dried and baked. This ball is cooled at a prescribed rate to deposit the needle crystal of 9Al2O3.2B2O3 or 3Al2O3.2SiO2 on the alumina ball surface.

This constitution reduces a step on a passage of wall current between the beam duct 1 and the wall current monitor while maintaining high airtightness of the beam duct 1. The high frequency contact 9, at this time, is not a passage of wall current but an electromagnetic shield.
