Title: Rapid solidification of plasma spray magnetic alloy
Inventor: BUITOO DABURIYUU SORANO
IPC: B22F9/08
Filed: 1988-09-24
Abstract: PURPOSE: To manufacture the magnetic alloy of fine structure through rapid solidification by directing the plasma flame in which the alloy is introduced toward a wall surface in a cylinder rotating at high speed, and spraying the inert gas flow at the position not to interfere with the flame. CONSTITUTION: Molten particles of the magnetic alloy are collided with an inner surface 62 of a rotating rapid-cooling cylinder 64. The inert liquefied ultra-cold gas such as Ar is ejected against the rapid cooling cylinder through a feed tube 66 from a gas source 70 to form a cold gas layer adjacent to the inner surface 62. The gas layer constantly cools the rapid cooling cylinder 64 to promote the heat transfer from the particles to the rapid cooling cylinder 64, and prevents adhesion of the particles 72 collided and cooled by plasma spraying to the inner surface 62 of the cylinder. The particles of the magnetic alloy high in yield and line in structure can be obtained from the molten rare earth transition metal alloy.

Title: Photomask and its production
Inventor: HOSONO KUNIHIRO
IPC: G03F1/68
Filed: 1990-09-07
Abstract: PURPOSE:To obtain a photomask without a stain layer and the level difference of a substrate by providing a metallic oxide film which can be etched between a mask substrate and a light shielding film, radiating an energy beam so that the defect of a pattern may be corrected, and then selectively removing the metallic oxide film. CONSTITUTION:The metallic oxide film 2 which has etching resistance to an etchant and which can be etched by a 2nd etchant that does not dissolve the light shielding film 3 is provided between the mask substrate 1 and the light shielding film 3. After forming the light shielding film 3 by the 1st etchant, the energy beam is radiated in a state where the metallic oxide film 2 is left all over the surface of the substrate so as to correct the defect of the pattern, and then the metallic oxide film is selectively removed by the 2nd etchant. Thus, ions do not get into the substrate at the time of correcting the black defective pattern of the mask, and the lowering of light transmissivity is prevented from occurring in the case of light transfer because of the level difference of the substrate.

Title: Apparatus for inhibiting surface chill mark
Inventor: HASEGAWA TORU
IPC: B41F23/04
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To effectively inhibit the occurrence of a surface chill mark which will otherwise stain a clean paper. SOLUTION: This apparatus is constructed in a manner such that it is able to wipe off a solvent attached on a cooling cylinder 10 of a cooling section of a wheel rotating type printing machine, so as to effectively inhibit the occurrence of a surface chill mark which will otherwise stain a clean paper. An aluminium roller 11 wound by a Morton cloth 12 is caused to rotate by means of a cooling cylinder 10, with a circumferential speed of the roller 11 being different from that of the cooling cylinder 10. In this way, it is easy to effectively wipe off the solvent attached on the cooling cylinder 10, thereby inhibiting the occurrence of a surface chill mark.

Title: Ignition controller of engine
Inventor: SHIMIZU HIROKAZU
IPC: F02P5/15
Filed: 1998-08-24
Abstract: PROBLEM TO BE SOLVED: To prevent an electric current from being still carried to an ignition coil even if an engine stall is caused after starting current-carrying when controlling the current-carrying timing to the ignition coil by measuring time from a control reference signal when a position sensor runs into trouble. SOLUTION: The ignition timing FADA is arithmetically operated as an angle up to the ignition timing from a control reference signal just before ignition (S4). When an engine speed REV is not more than a prescribed engine speed (S5) and a required current-carrying angle TDWLL (S3) is larger than the ignition timing FADV (S6), the ignition timing FADV is set to the current- carrying angle TDWLL (S7). Thus, while current-carrying to an ignition coil is started in synchronism with the control reference signal, the lapase of time corresponding to the ignition timing FADV is measured from the control reference signal to perform ignition by cutting off current-carrying to the ignition coil.
