IPC: H01R43/12
Filed: 1992-08-19
Abstract: PURPOSE:To prevent the generation of damage to a jig for positioning noble metal balls at the time of beam welding of an elastic metal plate and the noble metal balls. CONSTITUTION:Under the condition that noble metal balls 6 are received by recessed parts 15 of a positioning jig 14, recessed parts 16 of the bottom surface side of an elastic metal plate 12 are made to abut on a part of each noble metal ball 6. YAG laser beam is irradiated from the over of the elastic metal plate 12 to weld the elastic metal plate 12 with the noble metal balls 6, and thereafter, the elastic metal plate 12 is cut into the predetermined shape to form an elastic piece. The laser beam is received by the elastic metal plate 12, of which width is larger than that of the elastic piece, to prevent the arrival of the laser beam to the positioning jig 14.

Title: Heat exchanger including fin having louver
Inventor: KAWAI KAZUO
IPC: F28F1/12
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To provide a structure in which passage resistance of a gas stream with respect to a louver is reduced to improve performance of a heat exchanger. SOLUTION: When each louver 2 is assumed to be a blade type, the angle of incidence of a louver 2 with respect to a main fluidization direction 9 is set substantially zero, so that a gas stream 8 passing through a heat exchanger is prevented from being bent. Thus, passage resistance of the gas is reduced to increase a flow rate of gas passage for heat exchange. Further, the louvers 2 are arranged in a zig-zag manner each other along the main fluidization direction 9 of the gas, and an upper and lower uniform boundarw lower is formed from a square front edge portion of each louver 2 so that a lower stream louver for preventing such a boundary layer from being developed can be properly disposed and hence an average heat transfer rate of a fin itself can be improved.  The louver 2 is adapted to extend along the gas stream 8, so that the length 10 of the louver 2 can be shortened and hence a thin boundary layer is formed.

Title: Toner density detector
Inventor: NAGAYAMA KATSUHIRO
IPC: G03G15/00
Filed: 1992-08-20
Abstract: PURPOSE:To accurately detect toner density with a simple structure by providing a black photoreceiver for detecting a regularly reflected light from a toner carrier and toner image and a color photoreceiver for detecting random reflected lights. CONSTITUTION:A photoreceiver 22c receives a regularly reflected light of a light emitting element 22a via a transfer intermediate element (toner carrier) 2 or a toner image 3. A photoreceiver 22d receives random reflected lights. If a black toner image is detected on the element 2, a detected value of the light of the photoreceiver 22c is reduced, and as the toner density is raised, it is gradually reduced. Accordingly, black toner density can be detected by detecting regularly reflected light by using the photoreceiver 22c. The reflected light of the color toner is random reflected light. If a color toner image is formed on the element 2, as the toner density is raised, the random reflection amount is increased, and a detected amount of the photoreceiver 22d is increased. Accordingly, the color toner density is detected when the random reflection light is detected by the photoreceiver 22d.

Abstract: PURPOSE:To reproduce properly a long-time VTR tape using a standard VTR by controlling rotation phase either to advance or to delay a recording position for at least 0.5H of a rotary head to the tape in recording of video signals of odd or even fields. CONSTITUTION:A switch circuit 5 is changed over and controlled alternately in order by changeover control signal SW from an intermittent storage command signal CM changeover control circuit 11, and actuates a servo circuit 6 to cause it to start recording tracks TR1, TR3... at the position as shown in the figure A by giving rotary detection pulse signal PG to a direct phase comparison circuit 7 through a contact point N1 when the odd field tracks TR1, TR3... are formed by a head 1A. After completing the recording of TR1, TR3... a switch circuit 5 delays the signal PG in a delay circuit 8 for only 0.5H in a delay circuit 8 and gives the signal to the circuit 7. Therefore, a circuit 6 advances rotation phase of a drum motor 2 and compares a storage start position with TR1, TR3... to shift the position back to the position away from its proper position for 0.5H.

Abstract: PURPOSE:To execute appropriate degasification and to bake a loaf of bread having an excellent appearance when importance is attached to the baked up state of the loaf of bread by composing an operation control circuit so that it can selectively execute a manual degasifying course in addition to an automatic bread baking course. CONSTITUTION:When the importance is attached to the baked up state of the loaf of bread, the 'manual degasifying course' is selected by a selecting switch. In a 'fermenting process' in this 'manual degasifying course.' the respective operations of primary degasification and secondary fermentation are executed in the same manner as those in the 'automatic bread baking course', and when time for executing a secondary degasifying operation as last degasifying operation in the 'automatic bread baking course' comes, an informing operation to sound a buzzer 11 for two seconds is executed instead of secondary degasifying operation. At that time, a user opens a cover 4, takes out bread dough under a fermenting state, from the inside of a container 5 kneads the bread dough using hands and a rolling pin, and degasifies carefully. Thus, the loaf of bread having no pore and the excellent appearance can be baked up.

Title: Optical pulse compression device
Inventor: KAMIYA TAKESHI
IPC: H04B10/00
Filed: 1987-09-07
Abstract: PURPOSE:To miniaturize an external light pulse compressing device, by putting pulse laser beam components emitted from all optical waveguides of an optical waveguide array wherein the optical waveguides have a specific difference in overall length together into a single light beam. CONSTITUTION:The optical waveguide array 3 on which scattered light is incident consists of the individual optical waveguides (L2-LN), which have the specific difference in overall length in order. Scattered light components which pass through the respective different optical waveguides are delayed relatively on projection end surface and all the scattered optical components can be projected from the respective optical waveguides of the optical waveguide array 3 at nearly the same time. Pulse laser beam projected by an optical multiplexing element 4 consisting of an optical fiber multiplexer and a thin film optical strip line multiplexer is time-compressed by the optical waveguide array 3, so the light is laser beam with narrow pulse width. Consequently, the optical pulse compressing device can be made smaller in size than before.
