IPC: A63B102/32
Filed: 1991-03-19
Abstract: PURPOSE:To prevent the damage caused by a bending stress of a boundary of a face part and an extended part at the time of hitting a ball by forming integrally the face part and the extended part in the rear of a head from the face part, and joining the integrally formed part consisting of the face part and the extended part to other part. CONSTITUTION:A golf club head 10 is constituted of the part 10a containing a face part 11, and the main body part 10b. The part 10a has the face part 11, and an extended part 14 extended in the rear of the head 10, and the face part 11 and the extended part 14 are formed integrally by plastic working. The extended part 14 constitutes a part of a sole and a crown of the head. The front end face of the main body part 10b and the rear end face of the extended part 14 are joined by welding. At the time of hitting a ball 4, the face part 11 is curved like a bow by a cross sectional view, and to a boundary of the face part 11 and the extended part 14, not only a compressive stress but also a bending stress are applied. Since this boundary part is formed integrally, damage is not generated by a bending stress. On the other hand, onto a weld zone 13, only a compressive stress works, and a bending stress does not work, therefore, no damage is generated.

Title: Designing method of gate array
Inventor: REIMONDO JIYON FUERERI
IPC: H01L27/118
Filed: 1993-04-08
Abstract: PURPOSE: To form a gate array with high yield by discriminating unnecessary fixed metals for specific operation of a separated functional circuit by computer program and eliminating them. CONSTITUTION: Circuit, global and fixed metalization pattern are combined according to custom theory. Next, the result is inputted to a computer system, and when the system simulates it and judges that the pattern is selected correctly and coded, it generates the non-physical expression of chip design designated thereby. Then, it is discriminated which is not used among metalization shapes for connection of fixed metal (the computer searches for such a fixed metal shape that is not brought into contact with a circuit metal). Further the unnecessary fixed metal shape is removed from the non-physical expression. Finally, a circuit metal data pattern and changed fixed metal data pattern are combined, generating a final metalization data pattern.

Title: Method for discriminating deterioration of low alloy steel
Inventor: SATO TOMOKO
IPC: G01N17/00
Filed: 1985-04-19
Abstract: PURPOSE:To discriminate the degree of deterioration of a low alloy steel with high accuracy and good reproducibility by using the max. valve of the natural potential of the low alloy steel when the low alloy steel is brought into contact with an aq. soln. of an arom. compd. having either of hydroxyl group or carboxyl group and nitro group in a molecule. CONSTITUTION:An acidic soln. of 2, 4, 6-trinitrophenol is prepd. as the arom. compd. having the hydroxyl group and nitro group in the molecule and the acidic soln. of 2, 4-dinitrobenzoic acid is prepd. as the arom. compd. having the carboxyl group and nitro group. The pH values of each soln. are adjusted to about 2.4 and 2.2 respectively. Several kinds of Cr-Mo-V steels are immersed into such solns. and the max. value of the natural voltage is measured. The max. value of the natural potential changes linearly with the degree of embrittleness and since the potential migrates to the nobler potential as the embrittleness progresses and therefore the non-destructive detection of the deterioration of the mechanical characteristics of the low alloy steel with good accuracy is made possible.

Title: Check valve
Inventor: SAITO MORIO
IPC: F16K15/14
Filed: 1992-03-05
Abstract: PURPOSE:To provide a check valve having a less gas pressure loss by providing a diaphragm having a valve subjected to gas supply pressure at one side and back flow pressure at the other side, and another diaphragm subjected to the gas supply pressure at one side and atmospheric pressure at the other side, respectively in a casing. CONSTITUTION:Gas having the predetermined pressure, when supplied from a primary side feed port 7 to a primary chamber 4, acts on the inner sides 2a and 3a of each of diaphragms 2 and 3. As a result, the diaphragms 2 and 3 respectively warp externally to separate a valve 9 from a valve seat 11, thereby releasing the flow passage 9c of the valve 9. Accordingly, gas is then supplied to a secondary side appliance through a secondary side feed port 8. Thereafter, when the back flow of the gas takes place at the secondary side, due to a backfire phenomenon or the like, the diaphragm 2 instantaneously returns to flat state, and the back flow pressure is transmitted to an airtight chamber 5 via a through-hole 9a formed in the nutating projection 9b of the valve 9. Then, the diaphragm 2 immediately warps toward the diaphragm 3 because of the back flow pressure acting on the surface 2b of the diaphragm 2, and the valve 9 is caused to come in contact with the seat 11, thereby closing the passage 9c.

Abstract: PURPOSE:To variably control the cross sectional area of a parison in the peripheral direction thereof so as to obtain a desired wall thickness, in the blow molding of a thermoplastic resin, by providing a valve in the resin passage between a die and a core in a movable manner. CONSTITUTION:The thermoplastic resin melted and plasticized in an extruder flows between a valve 4 and core 2 through a resin passage 3 while distributed at the tapered part 4' having a circular cross sectional area of the valve 4 and reaches a tapered part 4'' having an oval cross sectional area. When the valve 4 moves downwardly and the base part of the oval tapered part 4'' is coincided with the lower end of the core 2, there is no change in the wall thickness of a molded parison in the peripheral diection thereof. When the valve 4 moves upwardly and the lower end surface of the oval tapered part 4'' is coincided with the lower end surface of the core 2, the wall thickness of the parison changes in the peripheral direction thereof and becomes max. In this case, the wall thickness of the parison is adjusted by the moving amount of the valve 4.
