Title: Golf club head and its manufacture
Inventor: TAKAHASHI OSAMU
IPC: A63B53/04
Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To provide a golf club head which ensures a long flying distance by curving the face part of a hollow body of club head so that the wall thickness is approx. equal in the vertical direction and small in the central part and large at the ends about the horizontal direction, and thereby equipping a trait with high rigidity and flexibility which are incompatible originally. SOLUTION: A golf club head has a hollow body 10, which is composed of an oversurface 12, a face part 14 formed on one side face adjoining approx. perpendicularly to the oversurface 12, and a side peripheral part 16 in a consolidated structure. The rear surface of the face part 14 is curved in such a way that the wall thickness is smaller as going nearer the center of the face part 14, so that a small wall thickness part 18 is produced relatively in the central part, and the wall thickness is equal in the vertical direction identical to the shorter sides of the face part 14 and is small in the central part in the horizontal direction identical to the longer sides of the face part 14 and large in the end parts continuously. This accomplishes meeting at the same time an originally incompatible demand of flexibility and high strength which is required of a face part 14.

Title: Refrigerator
Inventor: SHIMIZU TAKESHI
IPC: F25D21/08
Filed: 1998-10-20
Abstract: PROBLEM TO BE SOLVED: To defrost an evaporator quickly without leaving frost by stopping a fan for an arbitrary time before starting defrost operation of the evaporator through a defrost means. SOLUTION: During cooling operation, a microcomputer counts the integrated operating time of a compressor 20 using a function thereof, i.e., a timer, and makes a decision whether the integrated operating time of the counter has reached 8 hours. Upon elapsing 8 hours after previous defrost operation, the microcomputer makes a decision whether the inner temperature is lower than a set level. At a moment when the inner temperature drops below the set level, the fan 11 is stopped for an arbitrary time before starting defrost operation of the evaporator 10 thus enhancing defrost efficiency while eliminating frost.

Inventor: DOI MASAAKI
IPC: B21B37/18
Filed: 1985-12-28
Abstract: PURPOSE:To eliminate oscillation phenomena due to plate thickness correction and to quickly stabilize a plate thickness by setting a calculating period of time at a low stand speed longer for integration of deviation values from a thickness meter at the outlet side of a continuous rolling stand and conduction of automatic control of stand speeds. CONSTITUTION:A thickness of a rolling stock 7 is detected by a thickness meter 1 set at the outlet side of a continuous rolling stand 3i, thickness deviations from the meter 1 are integrated by an arithmetic circuit 5, and the speed of a mill motor 8 is controlled by an automatic speed regulator (ASR). In the case that a rotating speed (v) indicated by a tachometer 9 is low, a calculating period of time is made to be longer by an arithmetic circuit 6 so that a speed is slowly corrected to cover a long arriving time of the stock 7 at the meter 1. Therefore, the oscillation phenomena are minimized to quickly stabilize a plate thickness.

Title: Photosensitive transfer sheet

IPC: G02B5/20
Filed: 1989-11-20
Abstract: PURPOSE:To arrange multicolor images adjacent to each other and to enable them to be transferred without deforming even fine image patterns by rendering a strippable layer soluble in a developing solution. CONSTITUTION:An image is formed in the image-forming layer 3' of a photosensitive transfer sheet 10 formed on the strippable layer 2, and this layer 2 is soluble in the developing solution, but when the layer 3' is developed, the hardened image part 3' remains alone, and the layer 2 corresponding to the nonimage part is dissolved and removed. As a result, the image-formed transfer sheet 10 comprises the image part 3' having the strippable layer 2 as the underlayer and the nonimage part of a support 1 having the surface disclosed. Since the image-formed transfer sheet 10 is freed of an adhesive part, it is transferred to a substrate 4 for forming a color filter, and a second color image-formed transfer sheet 5 formed likewise is overlaid on a substrate 1, and since both 1, 4 can be slided on each other without sticking to each other, the arrangement operation of both image parts 3, 3' is facilitated, thus permitting arrangement of image patterns high in precision to be carried out in the case of transferring ultrafine images and the like.
