Title: Disk driving mechanism for floppy disk device
Inventor: KUSUNOKI MASAHIRO
IPC: G11B17/32
Filed: 1985-12-27
Abstract: PURPOSE:To position the spindle of the rotating mechanism for a disk with high accuracy by providing the 1st spring means which applies a force to an upper and a lower magnetic head during read/write operation and the 2nd spring means which applies a force to the upper and lower magnetic heads during the positioning of the disk. CONSTITUTION:A head arm 17 is provided with a spring 18 which presses the respective magnetic heads 14 against the disk 10. This spring 18 applies the force (tensile force) to the magnetic heads 14 so that the magnetic heads 14 contact the disk 10 with proper contacting force during read/write operation. The positioning leaf spring 19 is a leaf spring which increases the contacting pressure to the disk 10 by only a specific value for a magnetic head 14 on a side S1 during the positioning operation of the disk 10. When the disk 10 is positioned completely, the positioning leaf spring 19 leaves the head arm 17 on the side S1 with a pressure pin 24 which moves up and down. The additional pressure of the leaf spring 19 is pressure within a range based upon the extent of the stopping of the rotation of the disk 10 as an upper limit.

Title: Spacer for semiconductor device and method of forming the same
Inventor: KOBAYASHI KAZUHIRO
IPC: H01L31/02
Filed: 1996-10-17
Abstract: PROBLEM TO BE SOLVED: To inject and harden a transparent resin at once by coating a spacer resin on a bump-forming surface, laminating and pressing a sheet, hardening the spacer resin, and peeling off a flexible sheet to protrude the heads of bump electrodes from the resin surface. SOLUTION: Solder bumps 11 are formed on emitter and collector electrodes of photo transistors on a wafer 10. A transparent resin 4 is flowed over the wafer 10 until covering the heads of the bumps 11. A sheet 14 with a deformable adhesive layer 13 is laminated and pressed on the heads of the bumps 11 and resin 4 until the adhesive layer 13 on the bumps 11 deforms the transparent resin in an uneven shape, and the resin 4 is hardened. The sheet 14 is peeled off to form spacers with the extruded heads of the bumps 11 by the thickness of the adhesive 13 on the surface covered with the resin. Thus the forming and hardening of the transparent resin can be made by one step.

Title: Structure of semiconductor optical element
Inventor: TAKAMIYA SABURO
IPC: H01S5/026
Filed: 1985-12-24
Abstract: PURPOSE:To dissolve the destabilization of laser oscillation due to the reflected light as well as to suppress the optical crosstalk by a method wherein the planes of incidence of at least the central parts of the front end surfaces, which oppose to the ear end surfaces of the semiconductor lasers, of the monitor photo diodes are formed into inclined planes in such a way as to be cut inside over a range as wide as possible. CONSTITUTION:The groove width of a groove 14 separating a semiconductor laser and a monitor photo diode in each group of a plurality of groups of the semiconductor lasers L1-L3 and the monitor photo diodes P1-P3 is adequately narrowed and the planes equivalent to incidence on the front end surfaces of the monitor photo diodes P1-P3 are formed into inclined planes 15 in such a way as to be cut inside over a range as wide as possible to the rear end surfaces, from which back beams RP1-RP3 are emitted, of active regions AR1-AR3 in the semiconductor lasers L1-L3. Even though the back beams RP1-RP3 to be incided are somewhat reflected, the possibility that these are returned to the active regions AR1-AR3 in the semiconductor lasers L1-L3 is eliminated, the oscillation state in the semiconductor laser L1-L3 is stabilized, and at the same time, the groove width of the grooves 14 is narrowed. Thereby, the mutual leakage of light into the adjoining monitor photo diodes P1-P3 can be prevented and the optical crosstalk can be effectively suppressed.

Abstract: PURPOSE:To obtain the title plastic having high mechanical strength when being in service, when out of service degradable into components which are biologically highly safe and cause no environmental pollution, thus useful for garbage bags, etc., by incorporating an oxyacid (co)polymer with a hydrolase. CONSTITUTION:The objective plastic can be obtained by incorporating (A) an oxyacid (co)polymer, pref. polylactic acid with a molecular weight of 1X10<4>-300X10<4> (esp. poly-L-lactic acid) with (B) 1ppm to 1wt.% of a hydrolase (e.g. lipase, amylase, cellulase, lactate dehydrogenase). The present plastic can be produced through the following process: the component A is dissolved in a solvent such as chloroform or THF, and the component B is added to the resulting solution and the solution is cast on e.g. a glass plate followed by evaporation of the solvent into a film; alternatively, the components A and B are mixed in a powdery state followed by compression molding. The present plastic has high mechanical strength when being in service in a dried state, and, after out of service, when it is disposed of in a wet environment, the component B will be activated and promote the plastic's hydrolysis.

Title: Picture forming device
Inventor: KUME NOBUYUKI
IPC: G03G21/10
Filed: 1990-11-02
Abstract: PURPOSE:To prevent generation of a defective picture by arranging a member for giving a toner to an image carrier in the upstream of a cleaning blade of a cleaner, forming an area of no adherence of the toner in this member and also arranging a spacer roller in a developer side brought into contact with a part of the image carrier corresponding to this area. CONSTITUTION:A spacer roller 9 in a developer side is brought into contact with an image carrier 1 in a location corresponding to both end parts of a magnet roller 3 in a cleaner side and a part A where a toner layer is cut by an end part scraper 12. Since no toner is provided in this cut part, a contact pressure of a cleaning blade 2 with an image carrier 1 is large generated, that is, cleaning action is strong by the blade, so that the toner, sticking to this cut part, can be easily removed eve when the toner is pressed by the spacer roller 9. In this way, a space between a developing sleeve 11 and the image carrier 1 can be accurately held to always obtain a good picture.
