Title: Magnetic tape defect inspection device
Inventor: KOGA HIROHISA
IPC: G11B5/84
Filed: 1995-10-31
Abstract: PROBLEM TO BE SOLVED: To form an inspection device in an inexpensive and simple configuration and at the same time, accurately detect the defect of magnetic tape. SOLUTION: A magnetic tape 10 is run on a tape running surface 25a of a guide plate 25. Inclination surfaces 25b and 25c are formed at the edge portion of the running surface 25a. Light from an emission optical system 30 is applied to the plate 25 and the magnetic layer surface of the tape 10 which runs on the running surface 25a. Reflection light from the tape 10 is applied to a CCD line sensor to detect a defect based on a sensor signal. By running the tape on the running surface 25a, the vibration and curve of the tape 10 are prevented, thus accurately detecting a defect. Since the inclination surfaces 25b and 25c are formed, the quantity of light applied to the CCD line sensor decreases at the plate 25 where no tape 10 runs rather than the tape 10, thus easily discriminating the edge of the tape 10 and easily detecting the defect of the tape 10.

Abstract: PURPOSE: To make a sampling timing of a received multivalue signal accurate and stable by detecting a synchronizing index signal in a timing when the multivalue level signal takes a minimum voltage for a class A basic period and when the multivalue level signal takes a maximum voltage for a class B basic period. CONSTITUTION: A maximum/minimum voltage computing element 53 receives a discrimination signal G outputted from a basic period discrimination device 55 to detect a minimum value of data Q for a class A basic period, that is, a minimum voltage of a multivalue level signal and to detect a maximum value of data Q for a class B basic period, that is, a maximum voltage of the multivalue level signal. The amplification factor of amplifiers 11, 12 is subject to negative feedback control so that a voltage difference between the minimum voltage for the class A basic period and the maximum voltage for the class B basic period is a prescribed value. Thus, the voltage of each level of the multivalue level signal A is made stable.  A timing signal K to sample the signal A is generated and the signal A is quantized to each level by a quantization computing element/violation code discrimination device 54.

IPC: F28D15/02
Filed: 1986-12-01
Abstract: PURPOSE:To obtain a wick member free of lowering in tensile force or heat transfer efficiency, by depositing Cu, Al or the like on a substrate formed of polymeric fibers or a glass and having a multiplicity of open minute spaces, and the substrate is cleaned by heating in an aqueous solution of sodium hydrogencarbonate at a predetermined temperature for a predetermined period of time. CONSTITUTION:A substrate 1 having a multiplicity of open minute spaces is formed from polymeric fibers or a glass, then a metallic material 2 such as copper and aluminum is deposited on the substrate, and the substrate is heated in an aqueous solution A of sodium hydrogencarbonate at a predetermined temperature for a predetermined period of time, whereby the aqueous solution is converted to sodium sesquicarbonate, the surface of the metallic material is cleaned, and an oxide film is formed. Therefore, there is no possibility of lowering in the tensile force of the wick member thus obtained due to thermal damage to the substrate. Since the metallic material is not made extremely porous as in the prior art, there is no possibility of exfoliation of the metallic material or remaining of water vapor or the like in such pores, and the heat transfer efficiency of a heat pump obtained by use of the wick member will not be lowered.

Title: Recovery of gallium
Inventor: MINAGAWA YUKINORI
IPC: C01G15/00
Filed: 1985-12-18
Abstract: PURPOSE:To stably recover Ga for a long period, by bringing an aqueous solution containing Ga into contact with a granular material carrying a substituted quinolinol, adsorbing the Ga thereon and eluting the adsorbed Ga. CONSTITUTION:An aqueous solution containing Ga, e.g. an aqueous solution of sodium aluminate formed by the Bayer process, is brought into contact with a granular carbonaceous material, carrying a water-insoluble substituted quinolinol, e.g. 7-(1-vinyl-3,3,5,5-tetramethylhexyl)-8-quinolinol, etc., and having preferably >=10Angstrom  pore diameter to adsorb the Ga on the granular carbonaceous material. Ga is then eluted from the granular carbonaceous material with an eluent, e.g. sulfuric acid or nitric acid in >=0.5mol/l concentration, etc., and recovered. The Ga can be smoothly recovered by readier operation and smaller loss of the water-insoluble substituted quinolinol into the aqueous phase than in a conventional liquid-liquid extraction method. Since the deterioration of the individual granular carbonaceous material to be a carrier is remarkably reduced as compared with that of resins, stable operation can be continued for a long period.

Title: Dme system with broadcasting function
Inventor: OSHIDA NAOTO
IPC: G01S13/74
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To broadcast GPS reinforcing data by superimposing the GPS reinforcing data on distance information by effectively using frequency resources of a DME/TACAN band designated as an aviation band. SOLUTION: A header is added to DGPS reinforcing data to be broadcasted to an onboard system by modulating a transmission pulse level of a conventional ground DME(distance measuring equipment) system. The onboard system generates a threshold value of '1' and '0' by a level detecting device 5, detects a stating point of data by a header detecting means 6, and supplies the reinforcing data to the onboard system. Thus, a data broadcasting function is realized by superimposing GPS reinforcing data on distance information of DME. The DME avoids radio interference with an existing ILS, a VOR, ground-to-air radio communication and a broadcasting station since an L band is used.

Filed: 1985-12-20
Abstract: PURPOSE:To obtain titanium disulfide which is small in grain diameter and high purity and has Ti/S close to stoichiometric ratio by allowing titanium and sulfur to directly react in a vacuum sealed tube in the specified mixing molar ratio at the specified temp. CONSTITUTION:Metallic titanium and sulfur and mixed in inert gas so that Ti/S is regulated to 0.92/2-0.99/2 molar ratio. Then the mixture is vacuum- enclosed in a sealed tube and slowly raisen in temp. till 500-580 deg.C in such a state that the sealed tube is left to stand and reaction is performed for 30-100hr at this temp. After the reaction is finished, the sealed tube is cooled till the temp. close to ordinary temp. and dismounted in inert gas and a small amount of titanium trisulfide by-produced from the produced titanium disulfide is separated. When the above-mentioned Ti/S is larger than 0.92/2 molar ration, one part of titanium disulfide having the unspecified ratio plenty in Ti content is easily formed. Also when Ti/S is smaller than 0.92/2 molar ratio, the large amounts of titanium trisulfide are by-produced and yield is remarkably reduced.
