Title: Device for extinguishing arc
Inventor: OKADA TAKEHIKO
IPC: H01H9/44
Filed: 1991-11-11
Abstract: PURPOSE:To enhance the arc extinction performance of a device for extinguishing arc and prevent insulation deterioration of the device by preventing gas from flowing in behind a contact portion. CONSTITUTION:An arc extinction chamber 1 has an exhaust hole 4 provided through its wall 19 at one end and a contact portion 5 on its wall at the other end. A magnetic substance 2 is placed at the center of the arc extinction chamber 1 and is U-shaped and a pair of panels 8 are parallel and opposite to the side walls 6 of the arc extinction chamber 1 and form a space 7 for recirculation. A partition plate 3 has an opening 11 which allows the contact 5 to pass therethrough. When an arc is generated at the contact portion 5, the arc is attracted toward the back plate of the U-shaped magnetic substance and is extended and gas is allowed to move in the direction in which the arc extends. The gas is discharged from the exhaust hole of the wall at one end and part of the gas is recirculated toward the contact 5 through the space 7 for recirculation and is turned back by the partition plate 3 and allowed to enter into the magnetic substance and move toward the exhaust hole, and so the arc is quickly driven toward the exhaust by the pressure of the recirculating gas. Therefore, the arc voltage is heightened and the arc extinction performance of the device is enhanced. Because the partition plate 3 prevents the gas from flowing in behind the contact 5, insulation deterioration of the device can be prevented.

Title: Light wavelength meter
Inventor: TOKUHASHI ARINORI
IPC: G01J9/02
Filed: 1990-10-31
Abstract: PURPOSE:To achieve a higher stability by performing a wavelength measurement using a fixed Fabry Perot interferometer based on the results of the wavelength measurment using a two flux interferometer to facilitate a highly accurate measurement of an unknown wavelength. CONSTITUTION:Light 1 to be measured is branched in two with a halfmirror 2 and one part thereof is impinged into a two-flux interferometer 8 to detect an interference fringe thereof with a photodetecting section 10. The other part of the light is impinged into a fixed Fabry Perot interferometer 5 through a lens system 3. The lens system 3 works to expand a luminous flux or bring an angle of expanse to the flux so that four or six interference fringes with the interferometer 5 appear. Reference light with a known wavelength lambdatau emitted from a semiconductor laser light source 7 is branched in two with a halfmirror 4 and after impinged into the interferometers 8 and 5 respectively, the respective parts of the light are detected with a photodetecting section 9 and a line sensor 6. Output signals of the photodetecting sections 9 and 10 and the sensor 6 are processed with a signal processing section 11 to calculate a wavelength lambdax of the light 1 to be measured. The wavelength lambdatau is stabilized with a light source control section 12 so as to keep the interference fringe of the reference light with the interferometer 5 from changing.

Title: Directional coupler and manufacture of the same
Inventor: NOZAWA NOBUYUKI
IPC: H01P5/18
Filed: 1994-11-29
Abstract: PURPOSE: To easily adjust a coupling output again by laminating two kinds of dielectrics with different dielectric constants at least on a dielectric substrate and a microstrip line while dividing the lamination into plural times. CONSTITUTION: The directional coupler is formed by parallelly forming two 1/4 wavelength coupling lines composed of microstrip lines on the surface of the dielectric substrate with a space between. Two kinds of dielectric layers with mutually different dielectric constants are laminated on the surface of this dielectric substrate and the microstrip lines at least while dividing the lamination into plural times. As a result, since the amount of an electric power line between the microstrip lines to be leaked through the dielectrics into air is changed, the degree to improve the coupling output is changed. Therefore, the coupling output of the directional coupler can be gradually improved after design/manufacture. Besides, by applying the dielectric layers composed of resin, the dielectric layers can be easily formed on the surface of the dielectric substrate and the microstrip lines.

Title: Earth terminal mounting structure
Inventor: HATTORI KAZUHIKO
IPC: H01R11/12
Filed: 1995-10-17
Abstract: PROBLEM TO BE SOLVED: To simply remove an earth terminal out of a body. SOLUTION: An earth terminal 1 is formed with an insertion hole 11 for inserting the screw part 8 of a bolt 7, and a removal hole 15 located behind the insertion hole, which enables the head part 9 of the bolt 7 to be penetrated through. Both holes are communicated with each other through a narrow groove 16. Window holes 17 are punched out at both the sides of the groove 16, and this constitution thereby allows deformation allowable walls 18 to be formed at both the sides of the groove.  When the earth terminal 1 is pushed forward from a state that the earth terminal is mounted over a body 13 with the bolt 7, the knock of the screw part 8 of the bolt 7 against both the deformation allowable walls 18 causes the aforesaid walls to be deformed toward the inside of the window hole 17 in such a way as to be crushed, and the groove 16 is thereby widened, so that the bolt 7 is slipped out to the removal hole 15 while the screw part 8 is passing therethrough. Subsequently, if the earth terminal 1 is lifted up, the earth terminal 1 and a cable (a) are removed out of the body 13 while the head 9 is passing through the removal hole 15.

Title: Production of adsorbent from refuse incineration ash
Inventor: DANSEI YASUO
IPC: B01D9/02
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To carry out the removal, hydration, and partial mineralization of heavy metals to stabilize hazardous components with a relatively simple method, by putting refuse incineration ash under an alkaline condition, and by hydrothermally treating it. SOLUTION: Incineration ash is kept in a suspended state in an aqueous solution of an alkali such as sodium hydroxide and potassium hydroxide. Thereafter, it is hydrothermally treated for several hours or more at a temperature between 100 and 250 deg.C (optimally at about 180 deg.C) under saturation vapor pressure. Or, the incineration ash may be subjected to steam curing for several hours more at a temperature between 110 and 250 deg.C under saturation vapor pressure after being kneading with an aqueous solution of an alkali such as sodium hydroxide and potassium hydroxide to be molded. The reason why the temperature is set between 100 and 250 deg.C is that the temperature less than 100 deg.C makes the progress of the reaction difficult and the temperature above 250 deg.C not only makes the cost of a device high but causes the phase transformation of minerals to form a different crystal structure.

IPC: A61B5/025
Filed: 1989-11-16
Abstract: PURPOSE:To judge quickly and objectively the presence of cardiac noises on a display surface by monitoring whether or not the cardiac noises exceeding a discrimination level exist in expansion and contraction monitering periods of a cardiac sound signal from an acceleration type microphone. CONSTITUTION:A cardiac sound signal detected by a cardiac sound microphone 1 extracts I and II sound components through a low-pass filter 2 to regulate amplitude to a predetermined level with a first variable gain amplifying means 4. A second variable gain amplifying means 6 amplifies the cardiac sound signal having the low region noise removed by a high-pass filter 3 to be matched with a first amplified output in the amplitude. Also, a discrimination level is set by a discrimination level setting means 7 for matching. Further, a monitoring period setting means 5 sets contraction and expansion period monitering periods except for I and II sound generation allowing regions on the basis of a first amplified output. Thus, the cardiac sound signal of a second amplified output is displayed on an indicating device 9 and the contraction and expansion period monitoring periods and markers A, B for indicating the discrimination level are overlappingly displayed so that the presence of cardiac noises exceeding the discriminating level in each region can easily be found.
