Title: Parts separating method, its method, and method for stress relieving parts
Inventor: TOKUNAGA AKIHISA
IPC: B26D7/18
Filed: 1998-10-06
Abstract: PROBLEM TO BE SOLVED: To surely separate parts from a base material, and to shorten the time for separating the parts by holding a base material plate in a corrugated condition between pressing members, and reciprocating the base material plate or the pressing members. SOLUTION: A base material plate 101 is carried into a parts separating apparatus, and held between upper and lower conveyors 7, 4 in a sandwiched condition, and held by a base material plate corrugation keeping means 8 in a corrugated condition. The upper and lower conveyors 7, 4 are simultaneously moved forward and backward, and the base material plate 101 is advanced/ retracted by the friction force of the upper and lower conveyors 7, 4. The repetitive force is applied by the conveyors 7, 4 to generate the metal fatigue in the base material plate 101, and the base material plate is cut at each residual part and the parts are separated from the base material plate 101. Because the parts are separated in a sandwich-like held condition between the conveyors 7, 4, the parts are arranged relative to the plate, and carried out on the lower conveyor 4.

Title: Method and apparatus for measuring surface shape
Inventor: KUROKAWA KOTARO
IPC: G01B7/34
Filed: 1992-09-30
Abstract: PURPOSE:To accurately measure the slope of an object under test or the shape of a groove wall by a method wherein the central axis of a probe tip part is tilted to a scanning direction with reference to the vertical direction and an inclination angle on one side face is made large with reference to the scan ning direction. CONSTITUTION:The probe central line M is constituted to be tilted by an inclination angle of phi toward a scanning direction in such a way that the inclination angle theta1 of the side face 2A of a probe 2 becomes steep. When an object 3, under test, which is provided with a protruding part 3A composed of slopes 3B, 3C at different inclination angles beta1, beta2 is measured by the probe 2, the inclination theta2 of one side face 2B of the probe 2 is constituted to be beta1>beta2. As a result, the minimum distance between the side face 2B and the slope 3B is not changed until the tip 2 reaches a vertes 3D from a point 3a, and a tunneling position is not changed up to a vertex 3b. However, when the tip 2a reaches the slope 3C, the minimum interval between the probe 2 and the object 3 under test becomes the distance between true tip 2a and the scanning slope 3C.

Title: Resin molding method and resin molded product
Inventor: KUMAGAI YUKIHISA
IPC: B29D23/00
Filed: 1994-11-18
Abstract: PURPOSE: To enhance tensile and bending breaking strength while stabilizing quality by injecting a fiber-containing thermoplastic synthetic resin compsn. into a cavity from a gate to branch and fluidize the same within a resin molded product and putting the characteristics of a resin association part to practical use to largely change the orientation of the fiber in the reinforcing direction of the product. CONSTITUTION: A fiber-containing thermoplastic synthetic resin compsn. is injected into an injection mold by an injection means to mold an injection- molded product of a cylindrical test piece. In the injection process of the cylindrical test piece, when the injection of a molten resin into a product part cavity part 4 is simultaneously started from the gates 3A, 3B provided to a symmetric position with respect to the center axis of the region 4A corresponding to a flange part, a weld W is generated in the flange part 4A and a resin flows. As a result, the fiber in the molten resin is strongly oriented in the direction parallel to the center axis being the flow direction of the resin to largely enhance strength against tensile load. When the wt. average fiber length in the molten resin is large, this tendency becomes more marked.

IPC: B60R9/04
Filed: 1998-10-07
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of a shrink, and to improve fixing strength to a rail body by forming the inserting side tip of a connecting core material to the main body part in a pyramid shape gradually converging in the vicinity of the cross-sectional center as it proceeds to the tip. SOLUTION: A connecting core material 2 is formed, for example, of a material having proper strength such as aluminum die-cast, and is held in a metal mold by inserting the tip into a main cavity 3. This connecting core material 2 has a cross-sectional shape coincident with an inner peripheral cross-sectional shape of a rail body, and is formed in a pyramid shape such as the cross-sectional area gradually reduces as it proceeds inside the main cavity 3 from the insertion starting end of the main cavity 3. Thus, the vicinity of the holding part of the connecting core material 2 of a fixing leg does not suddenly change in a thickness by a stay of a melting resin 4, heat capacity per unit of the connecting core material 2 gradually changes by an inserting quantity to the main cavity 3, and since the melting resin is not uniformly cooled, a shrink to the surface is not caused.

Title: Medium-carbon and chromium series bearing steel
Inventor: HAMAMOTO MICHIO
IPC: C22C38/22
Filed: 1990-10-25
Abstract: PURPOSE:To improve toughness and rolling fatigue service life under atmosphere of lubricating oil mixing foreign matter by adding Si and Mo to medium carbon and medium Cr as blending component of specific composition and specifying area ratio of carbide or carbon-nitride with carburizing or carburized-nitriding treatment. CONSTITUTION:This medium carbon and chromium series bearing steel is the steel composed of by wt% of 0.4<=C<0.8, 0.3-1.2 Si, <=1.0 Mn, 2.0<=Cr<4.0, 0.1-1.0 Mo and the balance Fe and having the carbide or carbon-nitride at 15-25% the area ratio on the surface with the carburizing or carburized-nitriding treatment. In this steel, C improves mechanical strength and toughness and in the case of <0.4% C, the mechanical strength is remarkably lowered and in the case of >=0.8% C, the toughness is remarkably lowered. Si and Mo improve the rolling fatigue service life and in the case of being less than the lower limits, the effect is little and in the case of exceeding the upper limit of Si, the plastic workability is lowered and in the case of exceeding the upper limit of Mo, it becomes expensive. The above area ratio has little effect for preventing plastic deformation on raceway surface caused by entrapping the foreign matter in the case of being less than the lower limit thereof, and in the case of exceeding the upper limit the toughness is impaired and improved effect on the rolling fatigue service life cannot be anticipated.

Filed: 1999-10-06
Abstract: PROBLEM TO BE SOLVED: To provide a game machine capable of sufficiently arousing the thrills and excitements of a player and quickly advancing a game by developing a display game full of changes. SOLUTION: A display control part 150 executes a first display game likening to a slot machine first based on the entry of a game ball to a start port, suddenly announces the voice of 'reach' in the middle and switches from the first display game to a second display game. While the plural pieces of identification information for indicating an executed result are successively displayed in the first display game, the executed result of the display game of this time is displayed at once through a prescribed directing operation in the second display game. For instance, when Urashima Taro (a character from Japanese old tale) opens a casket, the executed result of '777' or '747' appears at once together with smoke.

Filed: 1986-12-01
Abstract: PURPOSE:To securely and smoothly wind a film in a film container by rolling the film and a back cover together, and separating a film which is already exposed from the back cover and winding it in the film container. CONSTITUTION:The film container 17 wherein the exposed photographic film is wound and stored while shielded from light and a back paper take-up shaft 18 for taking up the back paper 13 are put in the main body of a lens-mounted film unit which uses the photographic film with the back paper 13. The photographic film which is already exposed is separated from the back paper 13 and wound in the film container 17, and the back paper 13 is wound independently of the film. Consequently, although the photographic film with the back paper 13 is used, film development processing is performed as usual without any preprocessing after the film container 17 is taken out of the lens-mounted film unit after use.
