Title: Magnetic-head loading mechanism
Inventor: FUKAWA MASANORI
IPC: G11B21/21
Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To provide a magnetic-head loading mechanism by which a magnetic disk is replaced smoothly, whose maintenance and inspection operation is performed easily, in which magnetic heads are replaced easily and in which the respective magnetic heads can be loaded surely by a method wherein the magnetic heads can be changed over between a retreated state and an access state. SOLUTION: When both magnetic heads 2(A), 2(B) are loaded, both adaptors 71(A), 71(B) in a retreated state are turned at right angles in respectively opposite directions by a manual operation so as to be changed over to a brought- close state. Then, in the access state, both arms 3 are made parallel to each other in the same directions, both magnetic heads 2(A), 2(B) are brought respectively close to the faces of a magnetic disk 1, both rollers 714, 714 are brought respectively into contact with slopes on both side faces of a raising and lowering block 731, and both magnetic heads can be loaded.  At this time, the rear end of a push rod 73 is pressed by, e.g. an automatic control mechanism so as to be pressed down, the raising and lowering block 731 is raised up to a position indicated by a dotted line, and both magnetic heads 2(A), 2(B) can be loaded respectively on both faces of the disk 1.

Title: Copying device compensating for fatigue of photosensitive body
Inventor: IWAHASHI HARUO
IPC: G03G21/00
Filed: 1987-02-04
Abstract: PURPOSE:To suppress a sudden change in the density of a copy image by providing a means for controlling the charging current of a band electrode and the voltage of an exposure lamp in accordance with the temperature or the degree of fatigue of a photosensitive body and controlling the current and voltage respectively at different timing. CONSTITUTION:The copying device is provided with the means for controlling the charging current of the band electrode and the voltage of the exposure lamp in accordance with the temperature or the degree of fatigue of the photosensitive body and the current and voltage are controlled respectively at different timing. Since it is difficult to simultaneously control the correction of current and the correction of voltage when the number of operation bits in a CPU is reduced, respective corrections are executed respectively at the different timing values shifted from each other by a prescribed time when both the corrections are simultaneously commanded. Consequently, a sudden change in the copy density can be suppressed.

Title: Production of light guide
Inventor: TSUCHIYA AKIRA
IPC: G02B6/12
Filed: 1987-02-03
Abstract: PURPOSE:To simplify stages and to obtain a light guide which decreases leakage by forming a desired groove pattern on a substrate surface and filling the grooves with a gel-like material obtd. by hydrolyzing metal alkoxide, then subjecting the material to thermal oxidation, thereby executing the thermal oxidation of the Si substrate surface and the vitrification of the gel-like material simultaneously. CONSTITUTION:After the grooves are formed by anisotropic etching on the Si substrate 1, the grooves are filled by the gel-like material 4 obtd. by hydrolyzing the metal alkoxide. The upper part of the gel-like material obtd. by hydrolyzing the metal alkoxide is built up to a semi-circular shape at this time, as said material shrinks by about 10-20% when vitrified. After the gel-like material obtd. by hydrolyzing the metal alkoxide is filled in the groves, said material is thermally oxidized in a thermal oxidation furnace to form an SiO2 layer to serve as a clad layer on the groove surface and, at the same time, to vitrify the gel-like material obtd. by hydrolyzing the metal alkoxide, by which a light guide layer 3 is formed. The guide which deceases light leakage is thereby obtd.

Title: Curing treatment of thermosetting resin pipe
Inventor: KUSANO HIROSHI
IPC: B29C65/00
Filed: 1980-02-25
Abstract: PURPOSE: To cure the thermosetting resin formed on an insulating mandrel uniformly and rapidly and to miniaturize a heating furnace by heating the resin by microwaves.  
     CONSTITUTION: The thermosetting resin pipe 1 formed on a paper mandrel in the uncured state is between electrodes 4, 4 while being rotated, and then the resin is cured by microwave heating. Since metals hinder the induction heating by the microwave, the insulating mandrel made of paper is employed. Since the air gap between the electrodes 4, 4 is changed when the electrodes are placed in parallel with each other, the uncured resin pipe 1 is rotated to prevent the change of the gap. Resin mortar may be used as a resin. The frequency of the microwave is set to be in the range of about 1,000W10,000MHz. Accordingly, the resin can be cured uniformly and rapidly, enabling the heating furnace to be miniaturized.
