Title: Element fixing solder and manufacture thereof
Inventor: SUZAKI SHINZO
IPC: H01L21/52
Filed: 1989-12-21
Abstract: PURPOSE:To enable highly reliable fusion welding process to be performed within a short time by a method wherein an eutectic metal rolled out in specific thickness is degreased and then after removing an oxide film, oxidation preventive films are formed. CONSTITUTION:An eutectic metal 1 rolled out in specific thickness is degreased and after removing an oxide film, oxidation preventive films 2 are formed to avoid the reformation of the oxide film. Accordingly, even if the heater temperature is set up at higher level to increase the operational efficiency for fusion bonding a semiconductor element, etc., into a pedestal, etc., during the assembling process of a product, formation of oxide film can be avoided further to increase the bonding strength at the fusion bonded part because of the high temperature fusion bonding process. Through these procedures, the reliability on the products can be enhanced.

Abstract: PURPOSE:To accurately detect the edge position of a tire member by picking up an image of part of the object and generating a histogram, and detecting the edge position from its variation. CONSTITUTION:The image signal from an image pickup device 3 is A/D- converted by an input part 8, multiple gradation quantization is performed in an image storage part 9, and the image is displayed on a monitor 20 through an output part 19 and also sent to a cumulative density arithmetic part 10. The arithmetic part 10 cumulates and adds the density of each multiple- gradation quantized picture element in a window set in a picked-up image in the edge direction to generate the histogram at right angles to the edge direction. An offset quantity which is 1/4 as large as the maximum value of the histogram is added to the maximum value to set a reference value and positions which exceed the reference value are detected as the edge. The signal showing the coordinates of the edge is sent to a calculation part 11 to detect the actual edge position.

Title: Rotor winding of dynamoelectric machine
Inventor: CHIBA HIDEKI
IPC: H02K3/04
Filed: 1997-12-03
Abstract: PROBLEM TO BE SOLVED: To provide a rotor winding which are manufactured through the edgewise bending and soldering of multilayered conductors. SOLUTION: A ventilation groove 2 of an edgewise bending part is shifted to the outer diameter side of the edgewise bending to reduce the surface pressure of an inter-winding insulator, when a dynamoelectric machine is driven. A gap produced in the edgewise bending part is estimated beforehand to optimize a winding cooling structure. Furthermore, by shifting the ventilation groove 2 of the edgewise bending part to the outer diameter side of the edgewise bending, even if the winding is composed of a number of layers, the thickness unbalance of the ventilation groove 2 is not increased by the edgewise bending. Also, the connection area of the winding soldering part is increased to reduce the local heating of the soldering part and improve the strength reliability of the soldering part.

Title: Acoustic device
Inventor: YOKOYAMA KENJI
IPC: H04R3/00
Filed: 1987-12-28
Abstract: PURPOSE:To effectively reproduce a low-pitched sound even though a device is miniaturized by making a vibrator driving device control a driving state so as to reduce or invalidate internal impedance peculiar to a vibrator equivalently. CONSTITUTION:When a drive signal is given to the transducer 22 of the vibrator 20 from the vibration driving device 30 with a negative impedance driving function, the transducer 22 electromechanical-converts it, and reciprocates a vibration diaphragm 21 right and left in a figure and makes a mechanical sound. Thus, the internal impedance peculiar to the transducer 22 is reduced effectively. Accordingly, the transducer 22 drives the diaphragm as responding faithfully to the drive signal from the device 30, and gives driving energy independently to a Helmholtz resonator 10. At this time, the left surface side of the diaphragm 21 in the figure forms a direct emitting part for emitting the sound directly toward an external part, and the right surface side of the diaphragm forms a resonator driving part to drive the resonator 10. Thus, the sound of the diaphragm 21 is emitted directly, and the air of the resonator 10 is made to resonate, and a heavy and low-pitched sound is resonant-emitted from a resonant emitting part.
