Title: Casting method with lost foam pattern
Inventor: IMAI MINORU
IPC: B22C9/04
Filed: 1989-01-20
Abstract: PURPOSE:To make refractory fine particles close and to prevent the development of casting defect by applying solution containing binder as essential component on surface of a lost foam pattern, successively sticking refractory particles on the surface of the lost foam pattern and pressurizing the surface of the lost foam pattern. CONSTITUTION:The solution containing the binder as the essential component is applied on the surface of the lost foam patterns 1, 2 and the refractory fine particles are stuck to the surface of the pattern, and the surface of the lost foam pattern sticking the refractory fine particles is pressurized. As the refractory particles 6A are stuck to circumference of the binder layer 6, the defect part on the surface of the lost foam patterns 1, 2, in which the binder is already packed, is not invaded. The lost foam patterns 1, 2 sticking the refractory fine particles 6A are set to a pressurizing device and pressurized. The refractory fine particles 6A are pushed into the binder with pressurization and made to the invading condition in the height direction of the binder layer. By this method, the combining strength among the refractory particles is prevented from being damaged and the refractory on the lost foam pattern surface can be formed in perfect condition.

Filed: 1998-01-23
Abstract: PROBLEM TO BE SOLVED: To enable driving with completely new mechanism, miniaturization, and more efficient driving, by installing at least a pair of electrodes forming a moving flow of electrosensitive working medium by applying a voltage. SOLUTION: In the nearly central part of a driving shaft 118, a moving member 125 is axially fixed to the driving shaft 118. An electrode 121 is made as an anode, and an electrode 122 is made as a cathode. Decanedioic acid dibutyl is used as electrosensitive working medium 123. Between an inner cylinder 114 and a lid body 116a, a gap in which the medium 123 can flow is formed. The medium 123 which is formed between an outer cylinder 112 and the inner cylinder 114 and flows in the left direction inverts the direction by the lid body 116a, and forms a moving flow from the left toward the right direction inside the inner cylinder 114, which flow moves a moving member 125 toward the right direction.  When the electrode 121 is made as a cathode and the electrode 122 is made as an anode, a moving flow from the right toward the left direction is formed, and moves the moving member 125 toward the left direction. By repeating the above process, a linear motor is linearly driven.
