Title: Gas-cooking appliance
Inventor: SHIMADA RYOJI
IPC: F24C3/02
Filed: 1989-02-03
Abstract: PURPOSE:To prevent irregular cooking by disposing an upper burner at the upper part of a heating chamber and lower burners with blowing means and air ejection ports on the outside and both sides of the lower part of the heating chamber in a gas-cooking appliance which uses a city gas and the like. CONSTITUTION:An upper burner 13 and a lower burner 15 are ignited while a blower, which is not illustrated herein, is operated to send air into a blowing device 17. The air thus sent thereinto is ejected through an air ejection section 16 and smoothened by an air-flow direction plate, which is not illustrated herein, to control the direction of Bunzen flames formed by a flame hole row 14 of the lower burner 15. Accordingly, hot air streams generated on the right and left sides of the lower part by the lower burner 15 are directed toward the central vicinity of the lower part under a gridiron 10 while keeping a fixed direction and become ascending hot air streams. Consequently, the lower surface of a material 9 to be cooked is heated with a substantially uniform heat distribution. Accordingly, the material can be well cooked without being irregularly cooked.

Title: Space sampling transformer and image pickup device
Inventor: SHIRAIWA KEISHIN
IPC: H04N5/353
Filed: 1996-02-13
Abstract: PROBLEM TO BE SOLVED: To easily change image sampling characteristics and to improve image quality by controlling the relative position of a light receiving surface and an object image to the circle of a specified radius and an exposure timing. SOLUTION: An object 1 is passed through a photographing optical system 2 and parallel planar glass 3 provided with a prescribed angle to an optical axis and image-formed on an image pickup element 4. During an exposure period when the image of the object 1 is image-formed, the relative position of the light receiving surface and the image-formed object image is changed to plural positions on the circle or an approximate circle. For that, a rotation device 6 for rotating the parallel planar glass 3 by a rotary shaft parallel to the optical axis is provided.  Further, a timing signal generator 5 decides the radius and the exposure timing so as to turn the radius of the circle or the approximate circle to π/8-π/4 of a light receiving pitch based on the relative position data of a prescribed space sampling and controls an image pickup element driving circuit 7 and the rotation device 6. Thus, two-dimensional image sampling characteristics are changed by simple constitution and the image quality is improved.

Title: Auxiliary power supply device for motor-driven camera
Inventor: IWASHITA NORIYOSHI
IPC: G03B17/42
Filed: 1981-02-24
Abstract: PURPOSE:To avoid the damage of a film caused by an excessive torque for the power supply device of a motor-driven camera, by by-passing an overcurrent, if occurs, to a transistor. CONSTITUTION:An auxiliary power supply 7 is loaded to a camera incorporating a film winding motor 13 in order to increase the film wending speed and number of frames. As a result, a projection 10 operates a button 4 to open a switch  16. The two power supply batteries 15 and 17 are connected in series. In such a  case, an excessive torque is produced at the termination a film when the motor 13 is stopped to damage the film. In this respect, a protecting circuit is provided. This protecting circuit includes transistors 18 and 21 plus resistances 19  and 20. A transistor 21 is turned on by a large current which is produced when  the motor 13 stops. Thus the emitter potential of the transistor 18 lowers to  give a limit to the current supplied to the motor and the torque produced by  the motor.

Title: Ventilation fan
Inventor: HAGINO KAZUO
IPC: F04D25/08
Filed: 1986-02-07
Abstract: PURPOSE:To provide a ventilation fan of a large resistance against an external air flow speed in which an unstable static pressure-air flow quantity curve is removed and any extraordinary sound is prevented by radially providing a plurality of guide vanes inclined in the turning direction of an axial flow type impeller on the suction side of a bell mouth positioned at the outer peripheral portion of the impeller. CONSTITUTION:When an impeller 2 is rotated by a motor 1, indoor air is sucked up from a space between an ornamental panel 3 and a suction bell mouth 4. Upon this occasion, since a plurality of guide vanes 9 in each of which the inner diameter side is bent in the rotating direction of the impeller 2 shown by arrow 10, are attached between the ornamental panel 3 and the suction bell mouth 4, indoor air which has been sucked up pre-rotates to the rotational direction of the impeller 2 and flows into the impeller 2. Therefore, even at the same quantity of air flow, an angle of attack alphaA of a blade 2b toward a section 6 in the rotational direction largely decreases as compared with an angle of attack alphaB when there is no pre-rotation. Because the angle of attack alphaA decreases, an exfoliation starting air flow quantity decreases, and the outer peripheral portion of the blade 2b has larger pre-rotation and smaller angle of attack alphaA, the exfoliation does not occur in the full area at the same time, and hence a convex type function curve is not formed but the closing static pressure rises up.
