Title: Production of plastic molding
Inventor: NAKANO HIROSHI
IPC: B29C45/00
Filed: 1998-12-21
Abstract: PROBLEM TO BE SOLVED: To obtain a molding reduced in deformation and excellent in dimension al stability in a short time by molding plastic in specified conditions of a mold temperature, an injection pressure, and a resin temperature in a mold of a zinc alloy containing specified amounts of aluminum, copper, and magnesium. SOLUTION: A mold is made from a zinc alloy containing 5.2-8.6 wt.% of aluminum, 3.0-10 wt.% of copper, and 0.01-0.2 wt.% of magnesium. The aluminum is effective for improving the strength of the alloy, but the excess addition hurts the fluidity of the molten alloy and increases the amount of remaining bubbles in a cast. The copper increases the strength of the alloy, but the. increased addition lowers the fluidity of the molten alloy. The magnesium prevents intergranular corrosion but causes the lowering of an impact value with the increase of the addition. Plastic is molded at a mold temperature of 0-100 deg.C, at an injection pressure of 20-180 MPa, and at a resin temperature of 120-300 deg.C. In this way, a molding reduced in deformation and excellent in dimensional stability can be obtained in a short time.

Title: Magnetic bearing and control method of levitating body therefor
Inventor: IKEMOTO YOSHIHIRO
IPC: F16C32/04
Filed: 1998-12-25
Abstract: PROBLEM TO BE SOLVED: To easily control a position of rotor as a levitating body by providing a thrust magnetic bearing for holding the rotor in a shaft direction prescribed position and a means for controlling fluid by abutting to a position control part formed in the rotor and moving a floating position of the rotor. SOLUTION: A flow rate of fluid flowing to a pipe 20 changes by controlling a variable valve 23, and the fluid is pressed in a small diameter part 2a by passing through a through hole 2 of a rotor 1. At this time, the fluid abuts to a step difference 19 forming the small diameter part 2a, so that pressure of the fluid is applied to this step difference 19. Thus, since pressure of the fluid is applied in a since wave shape in the forward direction (the leftward direction) to the step difference 19, the rotor 1 being a levitating body reciprocates in the positive direction or the negative direction of the Z axis so as to balance with electromagnetic force of a thrust magnetic bearing, so that the magnetic bearing can reciprocate the rotor 1 in the positive direction and the negative direction according to a position command signal.  Thus, the step difference 19 functions as a position control part, so that the rotor 1 is positionally controlled by contact resistance of this position control part and the fluid.
