Abstract: PURPOSE:To circulatively use a small amount of cleaning organic solvent by providing a three-way valve on the way of a chemical supply line from a chemical pressure tank to a dispenser, and providing a circulation cleaning line of cleaning chemical in a separate system from the chemical supply line connected to the valve. CONSTITUTION:In the case of a normal chemical coating, chemical to be coated is charged in a chemical pressure tank 2, and the chemical is fed under pressure. The fed chemical is discharged from a dispenser 12 through a three-way valve 9 and a chemical supply line 11. When the line is cleaned, cleaning solvent 1 is sucked by a solvent circulation pump 7 through a three-way valve 5 and a filter 6. The sucked solvent is introduced to the line 11 through a three-way valve 8 and the valve 9. In this case, the stop valve of the dispenser 12 is so controlled as to be opened at a timing for discharging of the pump 7 to discharge the solvent from the dispenser 12.

Title: Scroll compressor
Inventor: HAYANO MAKOTO
IPC: F04C18/02
Filed: 1996-01-11
Abstract: PROBLEM TO BE SOLVED: To shorten an outer diameter without reducing strength shortage of a spiral body, and reduce thrust force by using a HFC system refrigerant including R32, and forming spiral bodies of a fixed and slewing scrolls in a shape which a thickness and a spiral pitch are gradually reduced from a center part toward an outer peripheral part. SOLUTION: In plate thicknesses t of the spiral body 29 of a fixed scroll 23 and the spiral body 35 of a slewing scroll 25, a center part is thickened, and it is gradually thinned toward an outer peripheral part. In a spiral pitch, a center part is enlarged, and it is gradually reduced toward the outer peripheral part, and the relation is represented as P1 >P2 >P3 . Even when large pressure difference is generated on a center part by a HFC system refrigerant including R 32 of high pressure, the strength shortage of the spiral body is not generated by the thick plate thickness range of each spiral body 29, 35.  Since the center part of the spiral pitch is enlarged and the pitch is gradually reduced toward the outer peripheral part, and the relation is identified as P1 >P2 >P3 , it is possible to reduce the outer diameter of the spiral body, and also it is possible to reduce thrust force.

Title: Transmission system of optical cable television
Inventor: RORUFU HAIDEMAN
IPC: H04J14/02
Filed: 1991-01-16
Abstract: PURPOSE: To transmit television signals through a signal optical waveguide by lowering a frequency band width to <=1 octave by dividing the full frequency band and performing single side-band modulation. CONSTITUTION: Wide-band frequency division multiplex signals are inputted to a point A, and two different band-pass filters B1 and B2 filter specific frequency ranges. Namely, a wide frequency band is divided into two auxiliary bands and optical transmitters 4 and 5 convert the signals into optical signals by making the width narrower than one octave, on the basis of the lowest frequency. Then a modulator 10 converts the signals into signals of a higher transmission frequency band, having a width narrower than one octave for single side-band amplitude modulation. The optical transmitters 4 and 5 form optical signals through the luminance modulation of a laser, and a multiplexer 6 combines the optical signals with optical wavelength multiplex signals. The multiplex signals can be transmitted to an optical receiving unit through a single optical waveguide.

Title: Bloch line memory element
Inventor: FUJIMOTO KAZUHISA
IPC: G11C11/14
Filed: 1992-01-13
Abstract: PURPOSE:To widen a margin for reading out and erasing without generating a malfunction and to provide a solid-state memory having high versatility by cutting magnetic domains by using two pieces of such parallel conductors with which a specific magnetic field distribution is obtainable. CONSTITUTION:Two pieces of the parallel conductors 10 which are formed via a spacer 14 on a ferromagnetic material 13 are used. The magnetic fields generated by the parallel conductors 10 when the currents equal in amplitude and reverse from each other are impressed to the respective parallel conductors have the characteristic that the place where the vertical components thereof on the surface of the ferromagnetic material film attain the max. value and the place where the intra-surface components of the magnetic fields on the ferromagnetic material film surface are zero at least coincide with each other. The stripe magnetic domains having a Bloch line are not cut and the generation of such a malfunction that the magnetic domains without having the Bloch line are cut is obviated if the operation to cut the magnetic domains is executed by using such parallel conductors 10. The margin for reading out or erasing is thus expanded.

Abstract: PURPOSE:To miniaturize a combustion chamber and a fan by a method wherein a flame port is divided into two parts and air is supplied to flames generating on the flame port from on both sides thereof through a secondary air inlet port and a tertiary air inlet port. CONSTITUTION:Flames generating on a flame port 7 are supplied with secondary air injected from both sides of the secondary air inlet port 8 and tertiary air injected from the center of the tertiary air inlet port 12 on the downstream side of the secondary air. As a result, even when the injecting velocity of each of the supply airs is low, the unburned component of a fuel at the center of each of the flames is supplied with a sufficient quantity of air so that the flame can be shortened and the blown air pressure is minimized to thereby miniaturize the fan and the combustion chamber at the same time. Further, due to the fact that the tertiary air inlet port 12 is provided on the downstream side of the secondary air inlet port 8, TDR is enlarged and the allowable range of the blow rate of the fan is extended to thereby facilitate the control of combustion of the burner.

Filed: 1999-01-11
Abstract: PROBLEM TO BE SOLVED: To prevent the ingress of foreign matters to a key insertion hole and to eject the foreign matters even when the foreign matters have entered the inside of the insertion hole. SOLUTION: A shutter 30 is arranged in a movable manner along the key insertion direction inside the key insertion hole 22. The shutter 30 is exerted always to the side of insertion hole opening 24 by a compression coil spring 40. In a state where no key is inserted to the insertion hole 22, the shutter 30 exerted by the compression coil spring 40 closes the insertion hole 22. Because of this, the ingress of foreign matters such as dust to the inside of insertion hole 22 can be prevented. Also, the shutter 30 is equipped a reflection surface 38, in a state where the key is not inserted to the insertion hole 22, the reflecting surface 38 reflects light from a light source 36 and the opening 24 of the insertion hole is illuminated.  Because of this, the insertion hole opening 24 can be visually recognized even when the vicinity of the insertion hole opening 24 is dark, and the key can be inserted easily into the insertion hole 22.
