Patent JP-S56159605-A (JP)
Title: Optical switch
Inventor: ITOU TAKAO
IPC: G02B26/08
Filed: 1980-05-14
Abstract: PURPOSE:To perform switching rapidly with low loss by moving a reflecting mirror by driving mechanisms so that while light emitted from an incident optical fiber is incident to the reflecting mirror via a lenslike medium, its reflected light is incident to emitting optical fibers via the lenslike medium. CONSTITUTION:Light emitted from an incident optical fibers 8 passes through a lenslike medium 9 and is reflected by a reflecting mirror 10 to strike the optical fiber 8 again. The lenslike medium 9 is placed its focal length away from the emission terminal of the optical fiber 8 and the reflecting mirror equally. Three driving mechanisms 11-a-11-b, such as solenoids, arranged behind the reflecting mirror 10 are operated individually or in pairs to slant the reflecting mirror, and consequently the reflected light is incident to each emitting optical fiber arranged closely to the optical fiber 8. Thus, switching is performed rapidly with low loss.

Patent JP-S57178421-A (JP)
Title: Alternating-current two-wire type contactless switch
Inventor: WATANABE YASUYUKI
IPC: H03K17/08
Filed: 1981-04-25
Abstract: PURPOSE:To protect a circuit by limiting an output current when a load short- circuits, and cutting off the output current when an output voltage further rises. CONSTITUTION:For example, a transistor (TR) 29 turns on and consequently TRs 28 and 6 turn on, allowing a current to start flowing. At this time, if a load 3 short-cjrcuits, the current increases suddenly. Then, a voltage across a resistance 15 rises and the base current of a TR6 is reduced so that a TR7 turns on. As a dresult, the collector-emitter current of the TR6 is limited to perform constant-current operation. At this time, the collector-emitter impedance of the TR6 is high, so a voltage at a terminal (a) rises. Therefore, a current flows to a Zener diode 12 to turn on a TR30. Then, the TRs28 and 6 turn off, thus protecting the circuit.

Abstract: PURPOSE:To easily produce a surface treated steel sheet excellent in weldability with certainty by adding specific amounts of Fe<3+> into an aqueous solution of inorganic acid, immersing a steel sheet into the above aqueous solution, and forming specific ruggedness in the surface of the steel sheet. CONSTITUTION:A bath is prepared by adding Fe<3+> by 1-50g/l, preferably about 3-10g/l, into an aqueous solution containing sulfuric acid, hydrochloric acid, etc., by about 10-100g/l. The above Fe<3+> is prepared by adding ferric sulfate or ferric chloride. Subsequently, a steel sheet is immersed for >=about 3sec into the above bath while maintaining the bath at about 30-50 deg.C, or, the steel sheet may be subjected to anodic oxidation for <=about 3sec in the above aqueous solution under the conditions of about 1-50A/dm<2> electrification density and about 1-10C/dm<2> quantity of electricity. By this method, a ruggedness of 0.01-1.0mum horizontal pitch and 0.005-0.1mum-Ra vertical depth can be formed in the steel sheet surface with certainty. Further, by plating this steel sheet with Cr, Ni, etc., a surface treated steel sheet in which ruggedness is allowed to appear at the plated surface and which has superior weldability can be obtained.

Title: Gas laser device
Inventor: TAKAGI SHIGEYUKI
IPC: H01S3/038
Filed: 1987-03-18
Abstract: PURPOSE:To enable uniform pre-ionization by separating a pin electrode pair on the upstream side of a laser gas flow to a main electrode from the main electrode at a distance where a product at the time of discharge does not reach. CONSTITUTION:Pin electrodes 14, 17 are each disposed on both sides in the cross directions of main electrodes 2, 3. A laser gas in a laser tube 1 is circulated to the electrode pair 14 from the electrode pair 17 by a fan 9. The electrode pair 17 on the up-stream side of the laser gas is mounted separated from a discharge space section 4 only at a distance where ions and electrons formed at the time of the pre-ionization discharge of the electrode pair 17 do not reach to the discharge space section 4. Accordingly, ions and electrons generated with ultraviolet rays applied from the electrode pair 17 disappear during the movement of a clearance, thus performing uniform pre-ionization, then highly repeating stable main discharge.

Title: In-liquid particulate using darkfield illumination and method for observing turbidity
Inventor: ISHIZUKI HIDEAKI
IPC: G02B21/10
Filed: 1999-02-04
Abstract: PROBLEM TO BE SOLVED: To make it possible to distinctly macroobserve up to the particles of sizes of micron order with a high magnification by visualizing the particles by the light scattering from the particulates in liquid by using a darkfield illumination method and monitoring the images through an optical fiber with the high magnification. SOLUTION: The direct light from an illumination light source 2 for illuminating a solution is removed by shielding plate 4 and the in-liquid particulates 5 is irradiated with the scattered light diffused by a light diffusion plate 3 in order to easily embody the darkfield illumination of the darkfield illumination device unit 1. Since the scattered light from the particulates 5 appears to glitter in a dark visual field by removing the strong light from the direct light, the observation of even a nearly transparent solution which is infeasible with an ordinary observation method is made possible. The scattered light from the particulates 5 is condensed by an objective lens 6 of a very small bore housed in an optical fiber housing cylinder 7 to an optical fiber 8 for observation, by which the images of the particulates are enlarged. The images are transmitted by the optical fiber.

IPC: G06F3/00
Filed: 1987-03-19
Abstract: PURPOSE:To minimize the necessary transmission of signals to the data buses by stopping the output port drive signal at a time point when a sense circuit detects a signal. CONSTITUTION:The output port drive signal 13D rises up synchronously with the rise of the synchronizing signal 11. When the data 160 is equal to '1', a data bus 120 is discharged and set at a level lower than the threshold voltage of a sense circuit 18. Thus, the decision output 151 is set at '0' and stops the signal 13D. The input port drive signal 14D also rises up synchronously with the signal 11 and transmits the signal of the bus 120 to an internal input 170. When the output 151 is equal to '0', the signal 14D is also stopped and an input 170 is latched. At the same time, the drive signal 11D starts the precharging when the output 151 is equal to '0'. Then the circuit 18 of the bit of the bus 120 is not actuated when the data 160 is equal to '0'.
