Title: Electrocast grinding wheel
Inventor: TAKAHASHI TSUTOMU
IPC: B24D3/06
Filed: 1990-09-28
Abstract: PURPOSE:To perform grinding at a high speed while holding a good cutting face roughness with smaller chipping, by forming plural abrasive grain layers in a lamellar shape with the dispersion plating process which uses plural kinds of plating liquids dispersing abrasive grains. CONSTITUTION:On the surface of a first abrasive grain layer 3, second abrasive grain layers 4, 5 which contain the abrasive grain in a relatively smaller grain size than the abrasive grain contained in the first abrasive grain layer 3, are formed. A main grinding is then performed on the first abrasive grain layer 3 containing the abrasive grain in a larger grain size and the small grinding at the vicinity of the contact part with a cutting face is performed on the second abrasive grain layers 4, 5 containing the abrasive grain smaller in grain size. Consequently, grinding can be performed at a high speed while holding a good cutting face roughness with less chippings.

Title: Magnetic disk
Inventor: ENDO YASUSHI
IPC: C09D175/06
Filed: 1989-10-04
Abstract: PURPOSE:To obtain the magnetic disk having excellent electromagnetic conver sion characteristics and good traveling durability by specifying the specific surface area, by a BET method, and saturation magnetization quantity of ferro magnetic metallic powder and incorporating polishing agent particles into a magnetic layer at a specific ratio with respect to the ferromagnetic metallic powder. CONSTITUTION:The metallic powder having <7.0 pH value, >=40m/g specific surface area by the BET method and >=130emn/g saturation magnetization quantity is used as the metallic powder of the magnetic disk. The polishing agent having >=6 Mohs' hardness is incorporated into the magnetic layer at 10 to 25wt.% with respect to the acicular ferromagnetic metallic powder. Since the ferromagnetic metallic powder which is extremely fine and is relatively large in the saturation magnetization quantity is used in such a manner, the electromagnetic conversion characteristics of the disk are excellent. In addition, the relatively hard polishing agent particles are incorporated into the magnetic layer and, therefore, the traveling durability is improved.

Title: Method for injection molding and mold apparatus therefor
Inventor: YAMAMOTO SETSUJI
IPC: B29C45/77
Filed: 1985-11-19
Abstract: PURPOSE:To prevent the occurrence of molding failure, by injecting a molten metal into a cavity after increasing the flow velocity of the molten metal flowing in a runner by narrowing gradually to the direction of a gate the molten metal poured into the runner leading to the cavity. CONSTITUTION:Molten metal A composed of a thermoplastic resin material is poured into a sprue 40 to flow into a runner 42, which is constituted in nearly same diameter with the sprue 40, so the pressure of the molten metal A is transmitted into the runner 42. Then the molten metal A gradually increases its flow velocity through the construction 48a of a connecting part 46, and flows into the gate 44 along a convex part 48. Frictional heat occurring at the connecting part 46 is discharged towards a bottom force itself 30. Also as the sectional area of a gate 44 is set smaller than the sectional area of the runner 42, the molten member A is not extremely heated and injected into the cavity to be solidified under cooling. Then after a top force itself 32 is moved upwardly, a moldings is released from the cavity 38 by lifting a extruded bar 50. Therewith molding failure do not occur on the surface of the moldings, therefore working processes are simplified.

Title: Cast connecting rod excellent in fatigue strength
Inventor: YAMAURA HIDEKI
IPC: F16C7/02
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To secure the fatigue strength equivalent to that of a forged connecting rod by forming a hollow part in a connection part through the machining to make the casting defects in a cast connecting rod harmless. SOLUTION: At cast connecting rod is of an H-section in a connection part 2, and a hollow part 6 is drilled. If defective casting is generated in a center of the connection part 3, it is removed by the drilling. In the cast connecting rod 1, the buckling resistance against the compression load to be applied to the connection part 3 when the engine is operated can be supplemented by ribs. In particular, the cast connecting rod has more degree of freedom in shape in addition to the connection part 3 than that of the forged connecting rod, and the height of the ribs can be easily increased. The moment of inertia can be improved without increasing the sectional area to satisfy the mechanical properties. The cast connecting rod can be made of spheroidal graphite cast iron, and the fatigue strength is preferably improved.

Title: Electrooptical apparatus
Inventor: MORIMOTO YOSHIFUMI
IPC: G02B27/46
Filed: 1988-10-14
Abstract: PURPOSE:To reduce a false color signal or moire by making the light flux separation direction of one birefringence plate coincide with a scanning line direction with the aid of a crystal optical filter obtained by superposing two pieces of birefringence plates and incorporating the other birefringence plate in the state that it is in the different direction from the scanning line direction. CONSTITUTION:The light flux separation direction of one of two birefringence plates is made to coincide with the scanning line direction, that means, the horizontal direction and simultaneously the light flux separation direction of the other one is made in the direction of an optional angle (theta) with respect to the scanning line direction. Therefore, though the unit light flux is separated to four light fluxes whose lightness is equal when it is passed through two superposed birefringence plates, the direction of the light flux separation and the distance of the light flux separation can be selected so that a shape obtained by uniting the respective points of the separated light fluxes is made a parallelogram shown by A-D. Thus, the response of a spatial frequency obtained in such a way can sufficiently suppress response in a spatial frequency which is a necessary cutoff frequency or more so as to sufficiently suppress the false color signal or the moire.

IPC: A61C13/08
Filed: 1998-09-14
Abstract: PROBLEM TO BE SOLVED: To improve elution resistance, corrosion resistance and organism compatibility of metal ion by forming a titanium alloy for an organism ideal for dental material such as the artificial root of a tooth and artificial bone material such as an artificial knee joint, of a composition containing Al and Ta at specific rates and the rest substantially comprising Ti. SOLUTION: A composition composed of Al of 4.0-7.0 wt.%, Ta of 8.0-18.0 wt.% and the rest substantially comprising Ti is used as a titanium alloy. Al used therein is used as an element effective to reinforce an α-phase and added at 4.0 wt.% or more to heighten alloy strength. However, if Al is added exceeding 7.0 wt.%, an α2 (Ti3 Al) phase is deposited to cause a lowering of ductility, so that the added quantity is suppressed to 7.0 wt.% or less. Ta is used as an element for stabilizing a β-phase in addition to its function of suppressing elution of Ti ion so as to heighten heat treating performance and to improve alloy strength.
