Inventor: NAKAGIRI YASUNOBU
IPC: H02K37/14
Filed: 1989-10-19
Abstract: PURPOSE:To improve incorporating accuracy by a method wherein a resin ring is fitted to the outer periphery of a cylindrical pole teeth unit, made by combining a flat flange type yoke with a cup type yoke, and the resin ring is compressed into the direction of thrust under a condition that respective yokes are incorporated. CONSTITUTION:The cylindrical pole teeth unit 1 of flat flange type yokes A, B are combined with the cylindrical pole teeth unit 3 of cup type yokes C, D under non-contacting engaged condition and resin rings G, H are fitted to the peripheries of said pole teeth units 1, 3 while toroidal type coils E, F are mounted on the circumferences of the resin rings G, H. In such a constitution, the positioning of the direction of thrust is effected by the resin rings G, H. In this case, the resin rings G, H are compressed between the end faces of te cup type yokes C, D into the direction of the thrust while the flat flange type yokes A, B are positioned in the direction of the thrust utilizing the resin rings G, H as spacers. According to this method, the incorporating accuracy of 4 pieces of yokes may be increased sufficiently with a simple structure without inviting the increase of the cost of a stepping motor.

Title: Method for washing phase shift mask
Inventor: NATSUME NORIYUKI
IPC: G03F1/26
Filed: 1992-09-16
Abstract: PURPOSE:To decrease the damages to be given on the surface of wiring patterns and to effectively remove foreign matter by passing the phase shift mask under water flow having ultrasonic vibrations in horizontal, perpendicular or other positions. CONSTITUTION:The water flow 1 having the ultrasonic vibrations is formed by using, for example, 'High Megasonic US Shower (R)' produced by Kaijo Co., and applying 95kHz ultrasonic vibrations to the water. The phase shift mask 2 arranged parallel on a transporting machine 3 is passed through this water flow. The water molecules having the ultrasonic vibrations vibrate the foreign matter intruding into the recessed parts of the mask. The foreign matter is thereby separated and removed from the mask together with the washing water flow. The resticking of the foreign matter once removed from the substrate is prevented by the water flow and the sticking of the foreign matter is decreased as compared with the conventional methods. As a result, the foreign matter on the surface is effectively removed without giving serious damages on the wiring patterns of the phase shift mask 2.

Title: Speaker diaphragm
Inventor: MATSUMOTO TOYOSAKU
IPC: H04R7/02
Filed: 1990-10-09
Abstract: PURPOSE:To easily obtain a flat and uniform frequency characteristic by forming a thin film whose major component is Au to the surface of a diaphragm made of a high elastic material. CONSTITUTION:A diaphragm 30 is formed by forming a thin film 12 made of Au directly to the surface of a Be diaphragm 10 with plating or vapor- deposition or the like. Since the sound velocity through the Au is much slower than that through a high frequency elastic material such as Be being a material of the diaphragm, the sound velocity is adjusted minutely to make the high frequency resonance characteristic smooth by forming the thin film using the Au as the major component to the surface of the diaphragm and a uniform film 12 is easily formed by plating or vapor-deposition or the like, Thus, the frequency characteristic is made flat and the diaphragm with a uniform frequency characteristic is easily obtained.

Abstract: PURPOSE:To prevent malfunction of an LSI and improve humidity resistance thereof by forming an organic thin film on the whole surface of the lead frames, semiconductor chip including the corner portions thereof and gold wires within the range of resin seal, and thereafter resin-sealing this. CONSTITUTION:By the use of a chemical or physical thin film forming technique, an organic thin film 9 of an leastic material which has a uniform film thickness, excellent adhesive properties and high purity is formed on the whole surfaces of the lead frames 3, 6, gold wires 5 and a semiconductor chip 2 including the corner portions within the range of resin seal, and this structure is resin- sealed. Since the organic thin film 9 contains no filler unlike the sealing resin 7 and it is highly pure and adhesive, it improves humidity resistance. Further, the organic thin film 9 can be applied to the whole surfaces including the corner portions with a uniform film thickness, stress effect is great particularly at the corners portions, and a uniform thin film is formed even in the inner surface of the anchor hole of the lead frame existing within the range of resin seal. Therefore, stress concentration on the inner surface of the anchor hole is relaxes, whereby the sealing resin can be prevented from being cracked or separated from the lead.
