Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To obtain an actuator, in which a piezoelectric element is used as a displacement element which reduces the voltage and the current of a drive signal, which reduces a power consumption and increases the output. SOLUTION: Two displacement parts, arranged so as to be nearly at right angles, are constituted of laminated piezoelectric elements 10, 10' and elastic members 25, 25' which are resonated by the vibration of the piezoelectric elements.

Inventor: SCHIRRA JOHN J
IPC: B22D17/20
Filed: 1999-12-20
Abstract: PROBLEM TO BE SOLVED: To execute die casting a member having high m.p. in a good condition by selecting the ratio of the inside diameter and the outside diameter of a sleeve so as to minimize the thermal deformation of the sleeve in the case of pouring molten material into the shot sleeve. SOLUTION: The cylindrical sleeve has the inside diameter Ri and the outside diameter Ro in the cold state, and as the molten material is poured into a low portion, the low portion is expanded more than the portion at the upper side and deformed as shown with the broken line to form an elliptic shape shown with a major axis Ma and a minor axis Mm. In such a case, the ratio (Ro/Ri) of the outside diameter and the inside diameter is desirable to be at least 1.5. In this way, the molten material having suitable volume, (particularly, in the case of filling only a small portion of the molten material), is formed as bow shape in the longitudinal direction or formed as the elliptic shape, and it can be sufficiently minimized that the sleeve is thermally deformed and the machine can be prevented from jamming. further, the inside diameter is desirable to be at least 1.5 inch.

For example, dechlorination of the source material is completely carried out and the devices are cleaned. By removing the chlorine ion, the corrosion resistance of the optical recording medium can be improved. Moreover, an inorg. protective film which increases the energy of light required for recording can be made thin or unnecessary.
