Title: Sampling device for casting
Inventor: AIZAWA TATATOMI
IPC: G01N33/20
Filed: 1980-07-14
Abstract: PURPOSE:To make unidirectional solidification possible, and obtain uniform test pieces from the same molten metal by providing a check valve in the lower part of a test piece metal mold and so constituting the same that a nozzle opens when the tip of said check valve abuts on the bottom of a melting furnace. CONSTITUTION:A test piece metal mold 3 is suspended from a wire rope 1 by means of hinges 2, and is immersed into the molten metal 5 in a melting furnace 4. When the tip of a check valve 6 in the lower part of the mold 3 abuts on the bottom of the furnace 4, a clearance is created between a nozzle 7 and the valve 6, and the molten metal 5 goes into the mold 3. When the mold 3 is hoisted upon sufficient entrance of the molten metal 5 into the mold 3, the valve 6 closes the nozzle 7, thereby preventing the outflow of the molten metal and obtaining a test piece casting 8. Since the molten metal enters the mold 3 in the bottom part of the furnace 4, the inclusion of gases and foreign matter does not occur. By the immersion of the removed mold 3 quickly into cooling liquid, forceful unidirectional solidification is developed and the uniform test piece is obtained.

Title: Narrow-band laser device
Inventor: WANI KOICHI
IPC: H01S3/137
Filed: 1989-04-14
Abstract: PURPOSE:To decrease the fluctuation of wavelengths due to the deformation of each Fabry-Perot(F-P) etalon by providing the F-P etalon having the narrowest transmission bandwidth out of F-P etalons at a place nearest to the 1st total reflection mirror in the 1st and 2nd total reflection mirrors and a plurality of the F-P etalons which make up an optical resonator. CONSTITUTION:This device is equipped with: a discharge tube 1; total reflecting mirrors 2 and 3; a semi-transparent mirror 4; F-P etalons 5 and 6. An F-P etalon having the narrowest transmission bandwidth out of the F-P etalons is installed at a place nearest to the 1st total reflection mirror 2. As a result, the energy of a light entering into a space where the F-P etalons 5 and 6 are installed decreases up to an extent that energy in the ordinary case is multiplied by transmission factor of the semi-transparent mirror 4. Further, the light attenuated by one F-P etalon enters into the other F-P etalon having the narrowest transmission bandwidth which determines the oscillation wavelength of a laser. The fluctuation of the central wavelengths of a laser light because of the deformation of each F-P etalon is thus decreased.

Title: Electronic control device for automatic speed change gear
Inventor: KIUCHI MORIO
IPC: F16H59/24
Filed: 1982-06-04
Abstract: PURPOSE:To obtain sufficient acceleration even just after an engine is started by shifting a speed-change point to the high-speed side for a fixed time just after the starting of the engine. CONSTITUTION:A shift-map selection subroutine decides whether a timer value is 0 or not, that is, whether a fixed time just after the start of an engine has passed away or not, and selects a high-speed side map when the timer value is not 0, that is, the fixed time does not pass away. When this high-speed side map is selected, shifting up or down is caused on the side of higher speed than the time when a low-speed side map is selected, and the range to use a gear in a low-speed step is expanded. Consequently, suffient acceleration can be obtained even just after the engine is started. When a fixed time has a passed away after the start of the engine, the timer value comes to 0, and the low-speed side map is selected to control the speed-change normally.

Title: Method for denitrification treatment of contaminated water
Inventor: NAKAMURA HIROSHI
IPC: C02F1/46
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To perform denitrification treatment of water contaminated with nitric acid at a low energy loss by using a denitrifying bacterium as a biocatalyst and electrolyzing the contaminated water with nitric acid at a low electric potential not generating hydrogen when denitrification treatment of the contaminated water with nitric acid is performed by reducing it. SOLUTION: A cathode 2, an anode 3 and a reference electrode 4 are installed in a reaction tank 1 and control is performed by monitoring electric potential of the anode by means of the reference electrode 4. A test water 6 contg. nitric acid and microorganisms is filled in the reaction tank 1 and while the inside of the reaction tank 1 is slowly agitated by means of an agitator 7, nitric acid is reduced while the electric potential of the anode is held at an electron receiving potential of the microorganisms (being lower than the hydrogen generating potential) by means of a const.-potential power source 5.  As there exists no large difference in the reduction speed of nitric acid in the case of the electron- receiving potential of the microorganisms and in the case of hydrogen generating potential, necessary electric power becomes approximately 20-30% lower than that in the conventional method.

Title: Steam condenser in power generation installation
Inventor: MORI MASATANE
IPC: F01K9/00
Filed: 1981-06-22
Abstract: PURPOSE:To prevent the lowering of vacuum of a condenser at the time of increase of a temperature of sea water and to contrive an improvement of thermal efficiency of power generation, by so constituting that water inlets are provided in shallow sea and deep sea, and connections between each of the water inlets and water supply opening of a condenser is made suitably switchable. CONSTITUTION:Operation is carried out by keeping a changeover valve 21 open and a changeover valve 26 closed, in winter, spring and autumn when a sea water temperature in shallow sea is low. Cold sea water of the shallow sea is led into a condenser 15 from a water inlet for condensation of vapor which is returned to sea through a discharge duct 23. When the sea water temperature of the shallow sea is high in summer, the changeover valves 21 and 26 are switched for closing the shallow sea side valve 21 and for opening the deep sea side valve 26. With this, vacuum of the condenser 15 can be maintained as high as it is in winter because far colder sea water from the deep sea is supplied to the condenser. Power generation capacity, therefore, can be maintained at constant fuel consumption all the year round.

Title: Two-dimensional scanning system
Inventor: OGIKUBO KAZUHIRO
IPC: G02B26/10
Filed: 1986-04-25
Abstract: PURPOSE:To realize high-speed or wide-angle scanning, by respectively rotating the 1st and 2nd rotary scan mirrors around the center line of a regular-polygon prism at different speeds. CONSTITUTION:The 1st and 2nd scan mirrors 8 and 9 respectively rotate in the direction shown by the arrows 11 and 12 around two axes which have a positional relation of torsion between them at revolving speeds of N1 and N2 (N1>N2). Rays of light are reflected by the 1st scan mirror and irradiated upon the 2nd scan mirror 9. At this time, the rays of light reflected by the 1st scan mirror 8 move clockwise on the xy plane. At the same time, the rays of light reflected by the 2nd scan mirror are scanned counterclockwise with a fixed angle being maintained with the xz plane, because the incident angle to the 2nd scan mirror changes. Therefore, two-dimensional scanning is realized, with the x-direction being subjected to line scan and y-direction to step scan. Moreover, when the revolving speed is made higher, high-speed scanning is realized, because the scanning speed depends upon the revolving speeds and numbers of surfaces of the mirrors.
