IPC: C10N40/24
Filed: 1979-11-19
Abstract: PURPOSE:To make it possible to carry out cold processing of alloyed steel, especially, a stainless steel easily, by a method wherein a metal surface is chemically treated by a treating liquid obtained by adding a water-soluble organo titanium compound to oxalic acid or a salt thereof and, thereafter, lubricating treatment is carried out thereby. CONSTITUTION:An oxalate coating is formed on a surface of a metal, especially, an alloyed steel, more especially, a stainless steel by a treating liquid with a relatively low concn. containing oxalic acid or a salt thereof as a main agent and a water- soluble organo titanium compound added thereto. Subsequently, by applying a lubricating treatment thereon, cold processing can be carried out easily and, moreover, in treating by a treating liquid prepared by further adding a poly-N-vinylpyrrolidone to aforementioned treating liquid, a good result is obtained against an alloyed steel, especially, an Ni-Cr type stainless steel. As a water-soluble organo titanium compound to be used, one forming a stable titanium chelate in an aqueous solution is used and, when this chelate compound is added to, for example, oxalic acid, one stable at an acid side of a pH 1-3 may be selected.

Abstract: PURPOSE:To obtain an excellent reproduced picture by forming a picture element electrode with a semiconductor film of a same conduction type as that of a storage diode and forming a picture element separation region of an opposite conduction type to that of the storage diode to part of the picture element electrode. CONSTITUTION:An n-channel poly-crystal Si film 18 being a picture element electrode is formed in a contact hole and on an insulation film 17, the surface is made flat and a p<+> inverting layer (picture element separation area) 19 is formed to a region of the poly-crystal Si film 18 subjected to picture element separation. Thus, it is not required to eliminate part of the picture element electrode 18 due to etching of the picture element separation or the like and no step difference is caused to the end of the picture element electrode 18. Occurrence of a picture defect due to electric field concentration at the picture element electrode end or deterioration in the remaining characteristic due to a defect density is in advance prevented.

Title: Method of measuring flying height of magnetic head

IPC: G11B21/21
Filed: 1992-05-18
Abstract: PURPOSE:To obtain a method for obtaining the true reflectivity of the surface of a slider of a measured head thereby to measure the correct flying height. CONSTITUTION:At the preparatory measurement, a transparent disc 5 is rotated with two different rotating frequencies, and the corresponding spectral patterns are detected. The intensity Irs of the spectral pattern, the reflectivity (r) of the disc measured separately and the temporary reflectivity (s) of a slider are applied to a theoretical formula, so that the flying heights hF1, hF2 for each rotating frequency is calculated. Then, the intensity Irs, the flying heights hF1, hF2 and the reflectivity (r) are applied to a theoretical formula, thereby to obtain a plurality of reflectivity curves of the slider surface corresponding to the wavelength of the reflectivity (s). The reflectivity curves of the flying heights hF1, and hF2 are compared with each other, and the reflectivity curve of the same reflectivity is selected. The same reflectivity is set as the true reflectivity sr of the slider surface. The intensity Irs of the spectral pattern detected when the transparent disc 5 is rotated at the regulated rotating frequency and the true reflectivity sr are substituted into a theoretical formula, and the correct floating amount hr at the measuring rotation speed is calculated.

Title: Color printer
Inventor: OSADA NAOMI
IPC: B41J13/22
Filed: 1993-05-31
Abstract: PURPOSE:To provide a color printer capable of removing the slackening of recording paper and the oblique winding of the recording paper around a platen roller and generating no misregistration. CONSTITUTION:After the completion of paper feed operation (P2, P3), recording paper 2A is reciprocally operated two or more times before the recording of a first color to remove the slackening or oblique winding of the recording paper 2A (P4). The recording paper 2A stored in a storage part 40 is unwound (P8) after the completion of the recording of one color and, thereafter, the slackening removing operation of the recording paper 2A further reversing a platen roller 13 by the integer number of rotations of 1 or more of the platen roller 13 is performed (P9). Since this integer rotation is performed by the number of rotations equal to the positive integer being the least common multiple of the values calculated with respect to respective speed reducing mechanisms by calculating the value wherein the greatest common multiple of the number of teeth of the large pulley of the same speed reducing mechanism and that of a timing belt is divided by the number of the teeth of the large pulley with respect to the respective speed reducing mechanisms, the recording shift due to the habit of a drive mechanism system can be prevented.

Title: Control device for working machine
Inventor: TADA MASAMITSU
IPC: B66C23/00
Filed: 1996-05-20
Abstract: PROBLEM TO BE SOLVED: To prevent the slippage of a reference working radius by making a reference working radius storage means store the actual working radius of an expansion boom tip part as a reference working radius only at the time of inputting a signal instructing vertical driving control from a change-over switch. SOLUTION: A reference working radius storage means 11a in a control signal output part 11 stores the actual working radius of an expansion boom tip part, obtained from an actual derricking angle θ and actual boom length L, as a reference working radius R0 only at the time of inputting a signal instructing vertical driving control from a changeover switch 8d. In case of inputting the signal instructing vertical driving control for the first time from the change-over switch 8d, the reference working radius R0 is rewritten since a flag is set to 0, but from the next time, the flag is set to 1, and vertical driving control is performed without rewriting the reference working radius R0. The slippage of the reference working radius R0 caused by the repetition of vertical elevation driving can be made very small.
