Title: Burnout point detecting method in incinerator using image processing
Inventor: MANAKO TAKAJI
IPC: F23M11/04
Filed: 1987-10-23
Abstract: PURPOSE:To get a stable sensing of a burnout point in an incinerator by a method wherein a brightness of an image element is monitored, a crossing point between a first brightness regression line calculated from a position where a brightness is rapidly changed and a second brightness regression line calculated from a combustion area including ashes is calculated to get a burnout point, a mean position of the burnout is set as a burnout point on an image. CONSTITUTION:A combustion area within a furnace chamber 4 is taken by a TV camera 13, an image signal is processed by a host computer 16 and an image signal processing device 14, a burnout point is detected, displayed on a TV set 15 and monitored by it. For example, a point N13 where the largest amount of positive variation of a variation of brightness on n3 is calculated and a position on the monitoring line n3 becomes a point A. A first brightness regression line 23 is calculated in reference to a brightness varying curve 21a and a second brightness regression line 24 is calculated from a brightness varying curve 21b in a combustion area including ashes. A position point B on the monitoring line n3 corresponding to a crossing point N3 of both brightness regression lines 23 and 24 is calculated to define it as a burnout point on the line n3. As regards other monitoring line n1, n2, n4, and n5, points N11, N12,...N15 expressing a maximum amount of variation of brightness and mean values of picture elements of burnout points are applied as a burnout point of the image.

Title: Brake mechanism for general-purpose engine
Inventor: MINENO KAZUO
IPC: F16D55/08
Filed: 1993-09-30
Abstract: PURPOSE:To simplify the structure and to improve durability by providing the center of turning movement of a brake lever on the part near the rotational direction side of a flywheel from the pressing position of a brake pad to the flywheel. CONSTITUTION:When the brake is applied to an engine in driving, a brake lever 10 is turned counterclockwise around the rotational center C by tensile force of a brake spring 13 by releasing force wherein an operator gripping a grip part 14A pulls the grip part 14A in the direction of the arrow mark Y2. And a protrusion 26 of the brake lever 10 is brought in contact with an engine stop switch 27, thereby the switch 27 becomes in the ON state, after that, a brake pad 11 is pressed so as to bite in the rotational direction of a lower surface part 19A of a flywheel 19. Thereby the brake is applied to the engine because the rotation of the flywheel in rotating in the direction of the arrow mark Y1 is stopped. Thus, a brake mechanism can be constituted of simple and a small number of parts.

Title: Radiation detector
Inventor: NAKAMURA SHIGERU
IPC: H01L31/09
Filed: 1990-10-04
Abstract: PURPOSE:To prevent a crosstalk generated between scintillator elements by covering the surfaces of the elements with a light reflecting film, and providing a spacer through the film. CONSTITUTION:A plurality of scintillator elements 4a, 4b, 4c,..., are disposed correspondingly on sensitive parts 7a, 7b, 7c of a board 7 through adhesive 10. A light reflecting film 6 coating the elements 4a, 4b, 4c,... is formed, for example, of aluminum. Grooves 13 are formed among the elements 4a, 4b, 4c,..., spacers 9 are inserted to the grooves 13, and stuck to the film 6 through the adhesive 8. The elements are coated with light reflector 5. Thus, even if lights generated from the elements are reflected at random therein, they are blocked by the film, and hence not leaked externally. Accordingly, since the light is not leaked between the adjacent elements, a crosstalk is prevented.

Title: Check valve of fuel inject pump
Inventor: NAGANUMA TAKAO
IPC: F02M59/46
Filed: 1990-10-04
Abstract: PURPOSE:To prevent irregular fuel injection by locating a throttle part to restrict over-lift of an aux. valve element in a position upstream of aux. valve element in a return hole. CONSTITUTION:Reflex pressure wave from a fuel injection valve presses downward a ball 3b and a ball holder 3a as an aux. valve, which results in downward movement of the ball 3b and ball holder 3a against the action of No.2 spring 4, and the ball 3b separates from a valve seat, 25d. Now the fuel returns to a compression chamber side space B from the gap between the ball 3b and valve seat 25d, and the residual pressure in the discharge line is damped. When downward motion of the ball 3b and ball holder 3a causes the tapered portion 3c of the ball holder 3a to move downward, the flow path between two tapered portions 3c, 25c shrinks. Accordingly an excessive return of the fuel through a return hole 25 is precluded by restriction of the amount of downward movement of the ball 3b and ball holder 3a due to shutting-off or the oil damping effect associate with shrinkage of the flow path between the tapered portions 3c, 25c. Thus an irregular fuel injection can be prevented.

Title: Electric part cooling structure of high-elequency heating device
Inventor: SUZAKU TAKAMICHI
IPC: F24C7/02
Filed: 1987-10-23
Abstract: PURPOSE:To reduce a blasting noise by providing an air flow direction plate formed with an arcuate orifice only at a position along the peripheral end edge of a cooling fan and facing normally a high frequency generator. CONSTITUTION:When a cooling fan 2 is rotated and driven, external air is introduced into a main body 1 of the device through a suction port 4. A part of an air flow is introduced into the upper position of a magnetron 5. Since an air flow direction plate 20 acts as a partition, no short-circuiting occurs and the cooling fan 2 always sucks up fresh air from the external part to send the same. An air stream led out from an orifice 21 and normally oppose the magnetron 5, and there is no loss due to the orifice 21. Further, no short- circuiting occurs and the air led concentratedly to the magnetron 5 to effectively cool the magnetron 5. Further, it is possible to sent an air flow having a low air flow pressure because there is no orifice in a high-tension transformer 6, and an air flow appropriate for the exhaust air route to improve the cooling performance.

Inventor: SAITO KENJI
IPC: F23G5/50
Filed: 1994-09-25
Abstract: PURPOSE: To enhance the combustion effect by removing ash content stayed on the surface of a burned material when waste having low heat generation amount such as garbage etc. is incinerated in an incinerating furnace of a stationary hearth, and agitating the surface of the burned material. CONSTITUTION: One or a plurality of air ports 5 are provided at the wall or the ceiling of an incinerating furnace 1.

The compressed air flowing operation is intermittently conducted in response to the forming velocity of the ash layer. A pneumatic pressure is regulated by a throttle valve 7 according to the state of the ash layer.

Title: Electrostatic capacity type humidity sensor
Inventor: ITAMI MASATO
IPC: G01N27/60
Filed: 1990-10-05
Abstract: PURPOSE:To improve environmental resistance and dependency on temp. by successively forming a lower electrode, polyimide moisture sensitive film and upper electrode on an insulating substrate. CONSTITUTION:The film of Mo is formed at 500Angstrom  thickness and the film of Au at 2,000Angstrom  continuously on a glass substrate and after the patterns of a resist are formed, the films are etched to form the lower electrode. A polyimide coating material, etc., are applied by spin coating on this electrode and is prebaked; thereafter a positive type photoresist is applied by spin coating thereon and is prebaked, exposed and developed, following which the resist is removed and the films are heat treated for 30 minutes respectively in the air kept at 200 deg.C and nitrogen atmosphere kept at 350 deg.C, by which the polyimide moisture sensitive film is formed. The Au is deposited by evaporation on this film to form the upper electrode having 100Angstrom  thickness. The dependency on temp. decreases if the thickness of the polyimide moisture sensitive film is reduced and, therefore, the dependence on temp. is improved and the environmental resistance, such as heat resistance, is improved from the instrinsic nature of the polyimide resin by confining the film thickness particularly to an about 0.5 to 1.5mum range.
