Title: Image recording apparatus
Inventor: HAKAMATA ATSUSHI
IPC: B41J2/44
Filed: 1988-02-12
Abstract: PURPOSE:To easily adjust each of recording colors and to well set color balance, by making it possible to respectively modulate a plurality of laser beams individually and performing modulation by separately setting a modulation time in a pixel unit. CONSTITUTION:Image data 32, 34 are inputted to pulse expansion/contraction circuits 41, 42 as binarized image data and the pulse expansion/contraction circuits 41, 42 expand or contract individually inputted image data and the corrected image data 43, 44 are inputted to laser driving devices 31, 33. The laser beams 12, 13 outputted from both of the first and second semiconductor lasers 14, 21 are adjusted to an almost equal shape at exposure places 19, 23 but, since the output characteristics of two recording colors are different from each other by the difference in the surface potential of a photosensitive body between two exposure places, the pulse widths of the image data 32, 34 inputted as pulse signals expand or contract. By this method, the modulation times of the semiconductor laser driving devices are differentiated and the density control of recording colors can be easily performed by adjusting the width of a line or surface in an electrostatic latent image.

IPC: C22C19/03
Filed: 1986-02-14
Abstract: PURPOSE:To manufacture a bolt of shape memory alloy easily fastened and detached, by subjecting a TiNi alloy having a specified compositional ratio to treatment of formation into single phase at a specific temp., to axis compression, and to aging treatment while holding it under compressive strain. CONSTITUTION:A bolt is manufactured by the use of an alloy consisting of 50.3-53.0at% Ni and the balance Ti. This bolt is heated up to >=600 deg.C to undergo treatment of formation into single phase, which is subjected to axis compression in the direction of length in a martensite-phase temp. region. While held under this compressive strain, the bolt is subjected to aging treatment at 400-600 deg.C. Thus-obtained shape memory alloy bolt reversibly repeats the elongation in a length direction at a temp. of an initial temp. of martensite transformation or below and the contraction at a temp. of an initial temp. of inverse transformation or above. Owing to the above characteristics, the length of bolt is arbitrarily changed, so that bolt can be firmly fastened or easily detached.

Title: High pressure water jetting device
Inventor: SATO TAKESHI
IPC: B24C5/04
Filed: 1999-02-05
Abstract: PROBLEM TO BE SOLVED: To improve durability of a nozzle for jetting high pressure water in a high pressure water jetting device for jetting high pressure water to an object from a nozzle to remove the surface layer of the object by forming a wear resistance coating film on the surface of the object side of the nozzle while the surface on the object side being covered with the coating film. SOLUTION: When high pressure water is jetted from a nozzle 1 by a high water feeding means 5, the high pressure water acts on an object to be peeled A to remove a coating layer W. At this time, a part of the removed coating layer W is scattered and the scattered materials P hit a surface 2a on the object side of a nozzle body 2. In order to cope with this, on the surface 2a of the object side, a wear resistance coating film 4 is formed by a high speed flame melt-spraying and by this coating film 4, the scattered material P are bounced back. Therefore, the nozzle body 2 is prevented from being directly hit by the scattered materials P, and as a result, it is hardly damaged. As material used for a melt-spraying coating film 4, for example, WC-Co alloy having high density and ultra hardness and excelling in wear resistance is used.
