Title: Geothermal power plant
Inventor: AMAMIYA HIDE
IPC: F03G7/04
Filed: 1984-09-20
Abstract: PURPOSE:To prevent discharge of hydrogen sulfide into the environment and deposition of sulfur in condenser by adding oxygen to non-condensive gas from an air extractor to remove sulfur from the cooling water in after condenser output cooling water piping and to remove oxygen from the cooling water in cooling water piping. CONSTITUTION:Hydrogen sulfide gas contained in the atmospheric air fed from an air extractor 8 in geothermal power plant is injected with oxidizing agent or oxygen through an oxygen injector 15 then the mixture gas is mixed with iron ion in an after condenser 9 to be converted finally into simple sulfur. Sulfur contained in the cooling water in the cooling water piping at the outlet of after condenser is removed effectively through a sulfur eliminator 16. While oxygen contained in the cooling water in cooling water piping 10 is removed through an oxygen eliminator 21 to deposit simple sulfur on a porous board in direct-contact condenser 4.

Abstract: PURPOSE:To obviate the refixing of a catcher each time in case of performing varied cloth extension by constructing the machine in such a way that the catcher moves on a cloth extending board integrally with a cloth extending machine main body when the cloth extending machine main body moves longitudinally on the cloth extending board. CONSTITUTION:The subject cloth extending machine is provided with a raw cloth holding mechanism 21 and a raw cloth delivery mechanism for delivering cloth from a raw cloth roll C1 held at the raw cloth holding mechanism. The raw cloth delivery mechanism is formed of a cloth releasing mechanism 27, a delivery belt 18 and a delivery roll 19. The end part of the delivered cloth is held by the holding member 52 of a catcher 3. The holding member 52 moves longitudinally in front of a cloth extending machine main body by the driving mechanism. The catcher is integral with the cloth extending machine main body and moves on a cloth extending board 2. In case of block cloth extension or extending cloth again in a different position on the cloth extending board, there is no need to refix the catcher, thereby improving the efficiency remarkably.

Filed: 1983-10-21
Abstract: PURPOSE:To obtain a character processor with which the editing processing has a quick response to an input with high operability even in case a long period of time is required for display, by deciding periodically or at irregular intervals the priority between the display processing and the editing processing. CONSTITUTION:The 1st input indicated by an input editing indication means starts the 1st editing processing, and the 2nd input starts the 2nd editing processing. The 1st and 2nd editing processings change documents and then start the 1st and 2nd display processings respectively to display the contents of documents and a cursor. A priority deciding means decides the priority according to a fixed system between the 1st display processing and the 2nd editing processing. The 1st display processing is first executed if this processing has higher priority. Then the 2nd editing processing is executed, and the 2nd display processing is carried out. When the 1st display processing has lower priority, the 2nd editing processing is first executed. Then the 1st display processing is performed, then the 2nd display processing is executed.

Title: Optical fiber unit for photoelectric switch
Inventor: SHINYA NORIHIRO
IPC: G01B11/00
Filed: 1994-08-23
Abstract: PURPOSE: To maintain a detection width having sufficient light quantity for a long time by making the diameter of arranged optical fibers larger than that of a central portion at both ends of linear arrangement to make the intensity of emitted light equal to that in the central portion without reducing it on both sides. CONSTITUTION: In an optical fiber unit of a sensor head for photoelectric switch, a plurality of optical fibers 1a, 1b from an optical fiber bundle 1c are linearly arranged at an end face 3 of the unit 2. The diameter of the arranged optical fibers is larger than that of a central portion at both ends of linear arrangement to equalize the intensity of light emitted from the end face 3. The diameter of the optical fiber 1a at both ends is selected and changed depending on application, type, and shape of sensor head or shape, dimension, aperture, and interval of the optical fiber 1b in the central portion. Although intense light is emitted from the optical fibers 1a at both ends there is no adjacent light like that in the central portion.  Therefore, light intensity at both ends of detection width comes near the light intensity in the central portion to create uniform light intensity over the whole detection width.

Title: Driving method for optical bistable element
Inventor: OKADA MASAKATSU
IPC: G02F3/02
Filed: 1988-08-11
Abstract: PURPOSE:To enable both setting and resetting operation with light pulse of a same shape by generating undershoot in outputted light and switching the outputted light from a high level to a low level. CONSTITUTION:An intensity P0 of outputted light is in the first stage at a low level L as compared to an intensity Pi of inputted light at a level PB of bias light, but the outputted light is switched by a setting light pulse to a higher level, and stabilized at a point H in a stationary state. When resetting light pulse having a same shape as the setting light pulse is impressed in this set state, the intensity P0 of the outputted light moves rightward transiently along a performance curve and the intensity is increased, but the intensity moves leftward as soon as the light pulse is eliminated, passing over the point H by the undershoot effect, passing further a switching point to a lower level. After it has fallen to a lower level, it is stabilized finally at a point L. Thus, both setting and resetting operations are executed with pulses having a same shape.
