Filed: 1984-07-20
Abstract: PURPOSE:To increase the melting speed of a pattern without the deterioration and defect of a casting mold contg. a consumable pattern and to make reusable the consumable pattern material by moving relatively the mold in a microwave shielding member and irradiating successively microwaves through a sprue part to increase the melting speed of the consumable pattern. CONSTITUTION:The casting mold 6 contg. the consumable pattern 2 is imposed on a rotary table 8 by positioning the sprue part 5 thereof to the bottom end. Such mold is disposed within the microwave shielding material 10. The pattern 2 melts successively and satisfactorily from the sprue part 5 when the microwaves are irradiated thereon through an irradiating port 11 and the table 8 rotates to descend. The deterioration and defects such as cracks of the mold 6 by the local melting of the pattern are eliminated and the melting speed of the pattern is increased. The deterioration of the consumable pattern material is decreased and the reuse of said material is made possible.

Abstract: PURPOSE:To enable the checking of the timing optimum for an exchange of an image forming solvent so that the coating of the contaminated image forming solvent can be prevented by counting the number of the times when said solvent is coated and announcing the exchange when a prescribed number is counted. CONSTITUTION:The image forming solvent 70 is coated on a heat developable photosensitive material or image receiving material by a coating member. The number of the times when the solvent is coated is counted by a counter means 87. The image forming solvent 70 in a storage tank 82 is contaminated by the gelatin, etc., stripped from the heat developable photosensitive material or image receiving material according to the frequencies of use and becomes inadequate for use. The fixed number of the coating times is previously determined by taking the condition of such contamination into consideration and the attainment of the fixed number is announced by an announcing means 89 when the fixed number as counted by the means 87 is attained with the heat developable photosensitive material. The image forming solvent 70 in the tank 82 is thereby exchanged at the optimum timing without being monitored at all times.

In addition, an A-phase signal, a B-phase signal and a C-phase signal which correspond to the movement in the Y-direction are obtained from terminals AY, BY in the same manner even in light paths of the beam of zero-order diffracted light R0 and beams of diffracted light RY+1, RY-1 in the Y-axis direction. That is to say, by this constitution, the relative displacement of the grating 21 on the scale 20 and a head part can be detected simultaneously in two X- and Y-axes.

Abstract: PURPOSE:To restrain reaction, prevent cracks, and facilitate exfoliating after processing by encapsulating a semi-melted state alloy ingot composed of a rare earth element, iron and boron in a metal capsule via releaser, and performing hot processing. CONSTITUTION:When a semi-melted state ingot of alloy whose basic components are a rare earth element, iron and boron is encapsulated in a metal capsule of S10C, SUS304, releaser such as boron nitride, alumina, sialon, etc., is spread.
