Title: Reflection type photocoupler
Inventor: OKAMOTO TETSUYA
IPC: H01L31/12
Filed: 1991-11-28
Abstract: PURPOSE:To obtain a reflection type photocoupler capable of suppressing the variation of the distance characteristic between light emission and reception and reducing its size, by forming its light emitting and receiving parts in a body. CONSTITUTION:A photoelectric conversion element 14 is mounted in a recessed part 15 of a resin package 11, and is wire-boned by bonding wires 29. To perform an optical isolation between the light emitting and receiving parts 12, 13 thereof, a resin plate 31 as a light shielding wall is inserted into a slit 28. The length of the light shielding plate 31 is set as large as the width dimension of the recessed part 15 of the resin package 11 so that the reflection light reflected by the inner wall of the recessed part 15 is not inputted to the light receiving part 13, and the inside of the recessed part 15 is molded with a transparent resin 32. Therefore, the variations of a focal distance and a depth of focus, each of which is one of the sensitivity characteristics of a photocoupler, can be suppressed. Thereby, since the space between the light emitting and receiving parts of the photoelectric conversion element 14 can be reduced easily, the optical path between light emission and reception is made short, and a large optical output can be obtained.

Title: Head control valve for ink jet printer
Inventor: MIYAZAWA HISASHI
IPC: B41J2/015
Filed: 1990-11-20
Abstract: PURPOSE:To obtain a control valve which is driven on less driving voltage and with less drive circuits for jetting of ink in high density by a method wherein a magnetic force generating part is formed of a plurality of magnetic force controlling plates arranged in the direction of passages and valves made of magnetic substances that are arranged in a plurality of places in each of the passages, and opening and closing of the passages is controlled with the above-mentioned valves combined with places wherefrom the magnetic force is generated of the magnetic force generating part. CONSTITUTION:Movable magnetic substances 3a and 3c are arranged respectively in passages 2a and 2b for an electromagnet 4x, the magnetic substance 3d is arranged in the passage 2b for the electromagnet 4y, and the magnetic substance 3b is arranged in the passage 2a for the electromagnet 4z. When electric current is applied to the electromagnets 4x and 4y, individual movable magnetic substances 3c and 3d in the passage 2b are made open because of the theory of opening and closing of a valve, and thereby the passage 2b is made open too. However, as the movable magnetic substance 3b in the passage 2a is closed, the passage 2a is closed. Because the opening and closing of the grooves are selectively controlled as mentioned above by combination of electrification to a plurality of electromagnets, control can be eventually made with less number of driving circuits.

Title: Laser beam ignitor
Inventor: SHIMADA EIJI
IPC: F42D1/04
Filed: 1991-09-24
Abstract: PURPOSE:To obtain safety by irradiating substance for causing an explosion reaction with a laser beam from a position at a safe distance to heat it to a temperature for causing the reaction thereby to generate the reaction. CONSTITUTION:Mixtrue gas containing 2:1 of hydrogen and oxygen by a volumetric ratio generates an explosion reaction at 550 deg.C or higher to generate a high temperature of 3500 deg.C or higher. However, since an explosion is strong and an explosion temperature is high in the ignition from a proximity distance, it is very dangerous. Further, the substance used for the ignition is largely damaged due to the high temperature. A laser beam consists of parallel rays and makes rectilinear propagation, but hardly makes divergence, causing a vary small decrease in its output. When the mixture gas containing 2:1 of the hydrogen and the oxygen in an oxyhydrogen explosion reaction chamber 4 is caused by heating explosion reaction with the beam 1 and hence the temperature of the chamber 4 holds 550 deg.C or higher, the irradiation with the beam 1 is stopped. The supply of the mixture gas containing 2:1 of the hydrogen and the oxygen is frequently reduced as much as possible.
