Title: Stator structure of motor
Inventor: ENDO YUICHI
IPC: H02K5/08
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To make it hard for resin on the surface of a stator core to exfoliate and to cause positioned shifts, and permit covering the surface of the stator core with resin uniformly over the entire surface by forming grooves in the surface of the stator core, and besides putting the resin on the surface of the stator core into the grooves. SOLUTION: A stator 1 of a motor has a stator core 2, having a rotor inserting hole formed in its central part. Then a groove or a plurality of grooves 6 are formed in the surface of the stator core 2 along its axial direction. The surface of the stator core 2 is molded with a resin 5, and the rear of the resin 5 on this thin film is put into the groove(s) 6. Consequently, the contact area of the stator core 2 with the resin 5 becomes larger, and the resin 5 becomes hard to exfoliate. As a result, the resin 5 put into the groove(a) 6 becomes a stopper and prevents the resin 5 from getting out of place in the circumferential direction. Moreover, the resin 5 passes the groove(s) 6 and flows smoothly, and uniformly covers the entire surface of the stator core 2.

Abstract: PURPOSE:To contrive to shorten a running time of carriers in a collector region of a bipolar transistor to speed up an operating velocity of the bipolar transistor by a method wherein an insulating layer is provided between any of a second region and a base electrode layer of a bipolar transistor, and a collector electrode. CONSTITUTION:A base electrode layer 9 connected by its own adjustment to an outer base region 4 is coupled to an outer peripheral portion thereof. Insulating layers 7 and 8 are arranged between the outer base region 4 within a base region and a collector region 2 or a collector electrode layer 1 positioned under the region 4. In other words, an inside edge portion on the side of an inside base region 3 of the insulating layers 7 and 8 is positioned inside the inside base region 3 rather than on the lowest side of the outer base region 4. The outer base region 4 and the insulating layer 8 surrounding the insulating 7 are basically contacted with each other. Since, with respect to a distance between the second base region and the collector electrode layer, a distance between the first base region (inside base region) and the collector electrode layer can be shortened, a practical thickness of the collector region is made thin to contrive to shorten a running time of carriers within the collector region and to speed up an operating velocity of a bipolar transistor.

Filed: 1981-09-24
Abstract: PURPOSE:To perform correct bonding of fine metal wires recognizing correctly bonding pads of a semiconductor chip by a method wherein a filter is provided in space between a television camera and the semiconductor chip. CONSTITUTION:The filter 30 is provided in space between the semiconductor chip 10 and the television camera 20.

The filter 30 transmits light reflected from the bonding pads, while light passed through the protective film is not transmitted. Therefore the television camera 20 recognizes only the bonding pads 7, 8 correctly. Thus bonding at the correct position is performed. Because the bonding pads on the semiconductor chip can be recognized correctly, and bonding at the correct position can be performed, and because the bonding device to enhance the good articles obtaining ratio in the manufacturing process can be obtained, the effect thereof is made remarkable.

Title: Resonance frequency adjustment method for piezoelectric tuning fork vibration
Inventor: KAIDA HIROAKI
IPC: H03H3/04
Filed: 1989-06-14
Abstract: PURPOSE:To adjust or change the resonance frequency of a piezoelectric tuning fork vibrator simply by adhering a mass to both vibration parts formed as a tuning fork to both sides of a slit symmetrically in the center of the slit. CONSTITUTION:Sets of mass 6a, 6b are adhered symmetrically to vibration parts 4a, 4b around a slit 3. This is because the waveform is split and the frequency is changed to the both when the mass is adhered to one side only.

The resonance frequency f1 is decreased more than f0 by nearly 4kHz as shown in figure. The resonance frequency of a piezoelectric tuning fork vibrator 1 is simply adjusted without change of the slit depth of the slit 3 and the thickness of the piezoelectric substrate 2 or the like by the addition of the mass 6a, 6b.
