Title: Photodetecting device
Inventor: NAKAMOTO HIROSHI
IPC: G02B6/42
Filed: 1988-01-18
Abstract: PURPOSE:To obtain the photodetecting device having a high optical coupling efficiency, and also, being miniature by sticking a condensing lens to the lower side face of a band-like core layer having an inclined end face which adheres closely and brought to optical coupling to the end face of an optical fiber and reflects the emitted light in the direction of the photodetecting surface of a photodetector. CONSTITUTION:On a circuit board 5 provided in parallel to an optical fiber 10 for transmitting an optical signal, a photodetector 1 whose photodetecting surface 3 has been turned upward is provided so as to photodetect the emitted light of the optical fiber 10. The end face of the optical fiber 10 adheres closely and brought to optical coupling to one end face of an optical waveguide body 20, and the other end face of the waveguide body 20 becomes an inclined end face 22-A. Also, a condensing lens 25 is stuck to the lower side face of a core layer 21 opposed to the inclined end face 22-A, therefore, the emitted light from the optical fiber 10 is reflected by the inclined end face 22-A, and thereafter, condensed to the photodetecting surface 3 by the condensing lens 25. Accordingly, even when the photodetecting surface 3 has been made narrow and small, the optical coupling degree is high, and the device can be miniaturized.

Title: Production of air-transmissible tacky tape or sheet
Inventor: TSUBOTA KENJI
IPC: A61L15/58
Filed: 1990-01-16
Abstract: PURPOSE:To obtain the title tape or sheet suitable as a medical tape in a simple process by spraying water containing a crosslinking agent onto a tacky agent solution layer formed on a release sheet, further drying the layer and laminating the resultant tacky agent layer onto an air-transmissible substrate. CONSTITUTION:A tacky agent such as rubber-based or synthetic resin-based tacky agent is dissolved in a solvent and the resultant tacky agent solution is applied on a release sheet to form a tacky agent solution layer. Then water in which a crosslinking agent for crosslinking a tacky agent such as dimethylolphenolformaldehyde resin is dissolved or dispersed is sprayed on the surface of the tacky agent solution layer while keeping the tacky agent solution layer in a undried state and the layer is further dried to form a tacky agent layer. Then the tacky agent layer is laminated on an air-transmissible substrate such as nonwoven fabric made of synthetic resin to provide the objective tacky tape or sheet.

Title: Molded motor
Inventor: KUROSAWA MASAHIKO
IPC: H02K29/08
Filed: 1992-01-20
Abstract: PURPOSE:To obtain ideal structure and characteristics by controlling a rotating speed by a signal of a Hall element by providing permanent magnets at opposed positions of the element of a rotor at a position separated farther than at least adjacent toothed part from a connected surface of a core integrated after winding. CONSTITUTION:A motor has a split surface 2 formed at an annular core 1 in a crescent state. When a stator is excited, a revolving magnetic field is generated at the core 1 by a main winding 3a and an auxiliary winding 3b, and a rotor is rotated by the magnetic field as an induction motor. In this case, since a permanent magnet provided at the rotor is magnetized in a circumferential direction, a variation in a magnetic flux is applied to opposed Hall elements 8, and electric signals are generated from the elements 8. Even if leakage magnetic flux is generated at the split surface 2 of the core 1, since the elements 8 are separated farther than a toothed part 6, it is not almost affected by influence of the leakage magnetic flux, and an output waveform of the element 8 becomes a sine wave, thereby accurately controlling a rotating speed.

Abstract: PURPOSE:To suppress the mixing of fine particles into an air layer formed around an optical disk and the deterioration of writing and reading characteristics by providing a through hole in an axial direction and a through hole connected to the lower face of a turn table and forming an air passage connected from the upper part of a clamper shaft to the lower face of the turn table by both through holes. CONSTITUTION:The through hole 5a in the axial direction is formed so as to be connected from the upper part of a clamper shaft 5 to a gap formed between a clamper 4 and the turn table 2 and the through hole 2a connected from the gap between the clamper 4 and the turn table 2 to the lower face of the turn table 2 is provided on the clamper 4. The air passage from the upper part of the clamper shaft 5 up to the lower face of the turn table 2 is formed by both through holes. Thereby, an air flow ordinarily passing a ball bearing part is almost removed and air is allowed to flow from the through hole of the clamper shaft 5, so that fine particles in lubricant are not almost mixed into a motor shaft 16. Consequently, the deterioration of writing and reading characteristics due to the sticking of an oil component to the surface of an optical disk medium or the lens surface of an optical head can be suppressed.

In this manufacturing method, after forming both impurity regions 6, 8 at the same time, the sheet resistance of the resistance impurity region 8 is measured to obtain the deviation from desired resistance value. According to the resistance value deviation obtd., a part of the resistance impurity region 8 is made amorphous by implanting ions or etched so as to adjust the element resistance.
