Title: Optical module for optical wavelength multiplex transmission
Inventor: IMOTO KATSUYUKI
IPC: G02B6/293
Filed: 1985-04-01
Abstract: PURPOSE:To simplify and economize an optical module by providing plural interference film filters at desired tilt angles between a photosemiconductor element and an optical fiber on the photosemiconductor element side with spacer glass between and arranging another photosemiconductor element on the optical axis of reflection of the interference film filters. CONSTITUTION:A light signal with wavelength lambda3 propagated in an optical fiber 12-2 for transmission as shown by an arrow 14 passes through a rod lens 35 to enter spacer glass 16, wherein the light becomes nearly parallel light; and the light is converged on the photodetection surface of a semiconductor photodetecting element 24 through a lens 23-1 after passing through an interference filter 19, spacer glass 17, an interference film filter 21, and spacer glass 18, so that the light signal is converted photoelectrically. A light signal with wavelength lambda1 which is emitted by a semiconductor light emitting element 25 is converted by a lens 23-3 into parallel light, which is incident on an interference film filter 20 at an angle theta1. The light signal with wavelength lambda1 which passes through the interference film filter 20 is incident on the interference film filter 19 and reflected in an angle direction of about 2theta1 to enter the rod lens 35; and the light is converged into the optical fiber 12-2 for transmission and propagated as shown by an arrow 13. Consequently, a small-sized, simple, and low-cost optical multiplexer/demultiplexer is obtained.

Title: Purging method and device for pressure atomizing type 2-fuel burning nozzle for gas turbine
Inventor: TAKAMI TOSHIJI
IPC: F02C3/20
Filed: 1978-06-05
Abstract: PURPOSE: To prevent a wrong ignition at a time when a turbine starts and to stabilize a starting, by purging in such a manner that introduces discharge air of a gas turbine, whose pressure is increased, to a liquid fuel passage of a nozzle.  
     CONSTITUTION: A purging air pipe 19 is connected with a liquid feeding pipe 4 running to a nozzle 2 of a gas turbine and at a discharge side of a check valve 5, and the pipe 19 is also connected with a discharge port of a turbine compressor. The compressor rotates with the turbine driven, and discharge air comes in a cylinder 24A through the pipe 19 and as a result it increases the pressure of the compressed air in the cylinder 24A. The air comes in the liquid fuel feeding pipe 4, and purges a fuel remaining in a liquid fuel pipe of the nozzle 2 and in a nozzle tip. Next, an air fuel is injected into a burner 1 from an air fuel feeding pipe 3 thorugh an air fuel passage of the nozzle 2. And thus, an excessive supply of the air fuel to the burner 1 can be eliminated, and a reliable ignition and a steady starting can be performed.

     CONSTITUTION: Sludge is fed under a condition having nearly constant thckness onto the initial part of a belt in a gravity dewatering zone 1. The sludge is gravity-dewatered through the back surface of the beltI during its advancement in the zone 1. When the beltI has passed through the gravity dewarering zone 1, the belt comes in contact with the periphery of a large-diameter main roll 4 at its outside surface on which the sludge is mounted, and moves nearly half or 3/4 round the lower surface of the main roll 4. The belt 1 moves round a final press roll 5-N, recedes to turn back from the main roll 4, successively comes in contact with press roll 5 on this side at its inner surface, and returns to a turn- back roll 2.

Title: Straight and purely short-chain peptide and its preparation
Inventor: OKADA KASHIO
IPC: A23J3/00
Filed: 1981-05-06
Abstract: PURPOSE: To prepare the titled peptide having a specific molecular weight, excellent in digestibility, and useful as a food for patients, etc., by extracting meat, etc. with hot water, treating the extract with proteolytic enzyme, separating, purifying and concentrating the product by ultrafiltration, removing the ash from the product by electrodialysis, and drying the product.  
     CONSTITUTION: Cattle meat or poultry meat (e.g. chicken bones with meat) is extracted with water in an extraction tank, and the eluted oil is separated. After separating the solid components with a centrifugal separator, the hot-water extract is decomposed by adding a vegetable-originated proteolytic enzyme (e.g. papain). The decomposition is further proceeded by adding a mold-originated proteolytic enzyme (e.g. Protease Amano  ), and the resultant partially decomposed protein liquid is subjected to the separation, purification and concentration processes by the ultrafiltration with a molecular sieve. After removing the ash from the product by electrodialysis or reverse osmosis, the product is dried to obtain the objective peptide having an average molecular weight of 1,000W10,000, high straight-chain ratio, and high purity.

Title: Signal discriminating circuit
Inventor: FURUSAWA YASUHIRO
IPC: H03K5/08
Filed: 1990-03-16
Abstract: PURPOSE:To easily discriminate an input signal even when it is a pulse signal with high frequency by outputting a high level signal obtained by an interpolating means by turning on the interpolating means when the input signal is a positive pulse signal or a high level signal. CONSTITUTION:When a positive pulse signal is inputted to an input terminal 1, a transistor(TR) Q1 is turned off only the high level period of the inputted pulse signal and held at ON in other periods. Thereby, a thyristor Th1 outputs pulse signals while repeating ON and OFF. On the other hand, the positive pulse signal inputted from the input terminal 1 is inputted also in an inverter 2 and its inverted signal is interpolated by the pulse signal outputted from the thyristor Th1 and turned to a high level signal on the anode side of the thyristor Th1. Since the thyristor Th1 is ON due to the input of the pulse signal to a gate, a high level signal is outputted to an output terminal 4 as a discriminating signal.

CONSTITUTION:An insulating film having a large bending rate, for example, Si3N4 (silicon nitride) film 9 is formed on the surface of a photodiode array 13. As a result, the incident X-rays on a scintillator array 14 are converted to light signals and thereafter, the light signals are converted to electric signals. The efficiency of light condensation can be enhanced by the presence of the insulating film having the large bending rate at this time and, therefore, the sensitivity of the photodiode array 13 is improved.
