Title: Shaft for golf club
Inventor: KAZAMA SHOICHI
IPC: A63B53/12
Filed: 1988-04-12
Abstract: PURPOSE:To form a desired pattern of a deflection deformation pattern of a club shaft by providing a ceramic layer or flame sprayed metal layer of high melting point metal on the surface of a shaft base member almost throughout the total length thereof and varying the thickness of said layer longitudinally of the shaft base member. CONSTITUTION:A first flame sprayed layer 15a with a uniform thickness is formed on the surface of a shaft base member 14 through the total length thereof. By adjusting the thickness of said layer the whole flexural stiffness of a shaft 11 is adjusted. Next, a second flame sprayed layer 15b is formed on the surface of a section A on the grip mount side of the shaft base member 14 so that the flexural deformation pattern of the shaft 11 is adjusted. Since in this case the flexural stiffness on the grip mount side of the shaft 11 is further improved by the increase of the thickness of said layer 15, a shaft liable to deflect on the tip end is made available so that a relatively high trajectory of a ball is obtained. The thickness varying pattern of said layer is thus properly set, so that the shaft having a desired flexural deformation pattern can be obtained without adding any variation to the shaft base member itself.

Title: Production of high-purity iron oxide
Inventor: KONDO HIDENOBU
IPC: C01G49/02
Filed: 1988-04-11
Abstract: PURPOSE:To stably obtain high-purity iron oxide having low SiO2 content, by concentrating acid cleaning waste liquid of hydrochloric acid of steel material, precipitating iron chloride crystal, partially collecting, dissolving the crystal in water or an aqueous solution of hydrochloric acid, filtering by a filter having a pore diameter of <=a specific value and burning or neutralizing the filtrate. CONSTITUTION:Acid cleaning waste liquid occurring in a process of washing steel materials with a solution of hydrochloric acid is recovered. Then the acid cleaning waste liquid is concentrated to precipitate iron chloride crystal, which is filtered from mother liquid. Then the iron chloride crystal is dissolved in water or an aqueous solution of hydrochloric acid, filtered by a filter having <=5mum pore diameter and the filtrate is burnt or neutralized to give high-purity iron oxide. Consequently, iron oxide having <=0.005wt.% SiO2 content usable as a raw material for soft ferrite can be simply and inexpensively produced without specific agents such as flocculating agent or surfactant.

Title: Double-port type static random access memory cell
Inventor: SAN HOO DON
IPC: G11C11/401
Filed: 1992-04-09
Abstract: PURPOSE: To obtain a memory cell, having a smallest silicon occupying area and high reliability by forming a double port memory by six transistors(TR) and providing a power source voltage line to supply a voltage at a prescribed intermediate level as well. CONSTITUTION: This memory cell is constituted of the six TRs of p-type TRs 28 and 34, controlled by word cables 44, 46 and p-type TRs 20, 24, 22 and 26 forming FF to be supplied with a power source voltage VC through a power source able 50. At the time of writing 1 in a port A in a state where a node X is 0, in advance to the writing, a voltage VC is dropped by not more than 50% to be the intermediate level. Then the conductive state of TR 24 is lowered by a node Y, to raise the potential of the node X. TR 26 comes into a double conductive state to further lower the potential of the node Y, and TR 24 becomes a non-conductive state to write data 1 by a stable flip operation. Similarly, using six TRs and high reliability using six TRs, asynchronous access is satisfactorily executed between ports A and B to make SAM of the smallest silicon area.

Title: Manufacture of cylindrical alkaline battery
Inventor: MUKAI YASUO
IPC: H01M4/08
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To reduce the internal resistance and improve the short-circuit current by inserting a positive electrode mix compact having a tapered circumferential surface into a positive electrode case with the larger circumferential side being on the bottom side of the positive electrode case, and pressurizing it in the positive electrode case, thereby enhancing the adhesion between the positive electrode mix and the positive electrode inner wall. SOLUTION: Positive electrode mix compacts 12a, 12b formed into hollowed cylinders mainly composed of manganese dioxide and graphite have tapered circumferential surfaces so as to be convenient for the release from a molding metal mold. A positive electrode case 11 consisting of a nickel plate steel plate is fixed to a holder 13, and the positive electrode mix compacts 12a, 12b are inserted into the positive electrode case 11 from the larger circumferential side. The center pin 15 of a molding die is inserted to the center parts of the positive electrode mix compacts 12a, 12b within the positive electrode case 11, and the positive electrode mix compacts 12a, 12b are pressurized by a pressurizing metal mold 14.  Since the clearance of the positive electrode mix compacts 12a, 12b with the positive electrode case 11 is narrower in a part closer to the bottom of the positive electrode case 11, the pressurizing force is uniformly worked.

Title: Check valve in hydraulic circuit
Inventor: KIKUCHI KAZUYUKI
IPC: A01B63/00
Filed: 1989-04-07
Abstract: PURPOSE:To prevent any hunting even at time of fluctuations in hydraulic pressure at the port side as well as to enable the simplification of constitution by installing a throttle port in a pilot spool of a check valve in a hydraulic circuit controlling a hydraulic cylinder for its expansion or contraction. CONSTITUTION:At time of expansion of a hydraulic cylinder 1, hydraulic pressure is fed to a B port from a pump port, and a pilot spool 4 is pressed to the side of a cover 11, opening wide the side of the cover 11 as well against a spring 13, and a notch part 9 is opposed to an A port. Accordingly, the hydraulic pressure by way of the B port extrudes a piston 6, lowering a working machine with its own weight W. At same time, drain oil pressure working on down side is made to flow into a tank port from the A port by way of a throttle port 5, while it is kept constant. In contrast with this, as for contraction operation, a partition part 10 is displaced to the B port side from the A port of a spool chamber 8 in the state that the pump port is interconnected to the A port and the B port is interconnected to the tank port, so that the hydraulic pressure working on the A port is not passed through the throttle port 5 and opens wide the cover 11, thereby pushing the piston 6 upward.

The inner pipe 2 is painted with mortar so that air and molten metal do not pass a fireproof lining 4 of a middle container 5 and is opened to a nozzle 6. When the closing/regulating mechanism 1 is opened, the molten metal passes through the nozzle 6 and flows out from the inside of the middle container 5. The inner pipe 2 has a cut-out 14 and the outer pipe 3 has an edge 15 at an end opposite to a retention piece 8. In inner and outer pipes 12 and 13, a sealing surface 17 or 18 is formed within a range 16 in the direction of an axial line. The outer pipe 3 is in an open position and the cut-out 14 is completely open toward the molten metal.  When the outer pipe 3 is rotated by 180 deg. from an open position with an ordinate line 13' as a center, the outer pipe 3 is in a closed position.

Abstract: PURPOSE:To prevent the abrasion of a photosensitive drum which is not concerned in forming an image by separating a transfer material carrying means from the image carrier of a remaining image forming station which is not concerned in forming the monochromatic image at the time of forming the monochromatic image of a specified color. CONSTITUTION:It is assumed that the image forming station 1 or 4 which transfers the formed image to a transfer material 6 first or last among plural image forming stations 1-4 is the image forming station of the specified color.

Namely, in the case of obtaining the desired monochromatic image, the transfer material 61 carried by the transfer material carrying means 51 does not come in contact with the image carriers 16, 26 and 36 of the image forming stations 1-3 which are not concerned in forming the image. Thus, the abrasion of the image carrier of the image forming station which is not used is prevented.
