Title: Information recording and reproducing device
Inventor: OGINO TSUKASA
IPC: G11B21/08
Filed: 1994-08-22
Abstract: PURPOSE: To correctly make a head accessible to a target position by calculating accelerations of the head with which the speed of the head becomes a target speed from the vicinity of the target position and controlling the position of the head based on the accelerations. CONSTITUTION: When a recording (or reproducing) instruction is transmitted from a host computer 11 to an optical disk device, a logical address transmitted from the computer 11 indicating a recording (or reproducing) position is fetched in a CPU 9 in the optical disk device. Next, an optical system 2 is controlled till the vicinity of the target position with a tracking actuator 3 by a feedback control. Then, the accelerations are calculated so that the speed of the optical system becomes the target speed from the vicinity of the target position by using a present speed and the target speed of the optical system 2 at the point of time when a next zero-cross is revealed and the distance between zero-cross points at every zero-cross elevation of the head. Next, the positional controls of the optical system 2 are performed based on these accelerations.

Title: Substrate for wiring board
Inventor: MATSUURA SHUICHI
IPC: H05K1/03
Filed: 1989-07-28
Abstract: PURPOSE:To obtain a substrate for wiring board which can be formed at a low temperature and is excellent in solvent resistance and heat resistance by applying varnish containing a precursor of a specific polyimide resin to metallic foil in a state where the varnish is expanded by flowing and drying the varnish. CONSTITUTION:A polyimide resin 1 expressed by formula I is formed on metallic foil. In order to form the resin 1 on the metallic foil, precursor varnish of the resin 1 is first applied to the metallic toil in a state where the varnish is expanded by flowing and dried. At the time of drying, the metallic foil is heated at a temperature at which the used solvent is removed and the precursor completely changes to imide simultaneously with or after the solvent is removed. When a film of a polyimide type resin is pressed against the metallic foil to adhere to the foil by heating, the film of the resin 1 can be formed on the foil. In this case, the heating temperature must be set at a temperature higher than the softening point of the resin 1 when the polyimide type resin is the polyimide resin 1 and a temperature which is sufficiently high to completely change the precursor to imide when a polyimide type resin is used as the precursor. When the polyimide type resin is a film-like substance, the metallic foil, polyimide type resin, and a supporting body are successively piled up and pressurized in a heated state.

Abstract: PURPOSE:To culture and propagate sulfur oxidizing bacteria within a short time and lower the treatment facility and treatment cost by combining calcium, regarding a fixing carrier of sulfur oxidizing bacteria for a fixed bed type bioreactor for waste water treatment using sulfur oxidizing bacteria. CONSTITUTION:To prepare a fixing carrier suitable for sulfur oxidizing bacteria to be used for a fixed bed type bioreactor 8, a calcium compound is added to a part of raw materials of the fixing carrier. Consequently, sulfuric acid produced by oxidation of a reductive sulfur compound by sulfur oxidizing bacteria and the combined calcium compound react and thus fine particles of gypsum are formed on the surface of the fixing carrier. The sulfur oxidizing bacteria adhere to the gypsum and are fixed and thus the bacteria are suppressed from lowing out to the treating water from the bioreactor 8. As a result, the sulfur oxidizing bacteria of the bioreactor 8 are kept at high concentration and treatment of waste water containing reductive sulfur compounds can be carried out highly efficiently and the quality of the treating water is improved.

Inventor: NAKAMA KAZUO
IPC: C22C38/00
Filed: 1996-07-26
Abstract: PROBLEM TO BE SOLVED: To improve hot workability and corrosion resistance by specifying the composition of elements. SOLUTION: This stainless steel has a composition containing prescribed amounts of C, Si, Mn, S, Ni, Cr, Mo, N, O, and Fe and satisfying Ni+27C+23M +0.1Mn-1.2(Cr+Mo)-0.5Si<=-20. The left side of the inequality is an index representing the degree of stability of ferrite phase and indulgences hot workability. Although the addition of Pb for securing machinabiliy causes deterioration in hot workability, workability can be recovered by forming the composition in the hot working temp. region into nearly ferrite single phase by satisfying the conditional inequality.  Further, Mn/S-0.17(Cr-16.5)<=12 is satisfied and the left side of this inequality is a factor for determining the composition of sulfide within the range of Cr content (16.5-22.0wt.%), and this condition in specified because the amount of Mn in the sulfide becomes larger than the amount of Cr and corrosion resistance is greatly deteriorated when the value exceeds 1.2.
