Abstract: PURPOSE:To prevent the generation of a cavity and seizure by turning back a runner provided along the centrifugal force working direction from a sprue of a mold, from the halfway, providing a casting chamber on the sprue side, and executing the casting from the direction opposite to the centrifugal force working direction. CONSTITUTION:A runner 2 from a sprue 1 is turned back by 180 degrees in a U-shape in the direction of the sprue 1 on the halfway, and in its tip, a casting chamber 3 formed after the shape of an ornamental article, etc., is provided. Platinum molten metal cast in from the sprue 1 advances along the centrifugal force working direction through the runner 2 and runs against the turning-back part, but is pushed by a molten metal which comes successively, and advances slowly in the direction of the casting chamber 3 against the centrifugal force. A flow of the turned-back moltem metal becomes a laminar flow and entrainment of gas is less, and generation of a cavity can be prevented. Also, by drying a mold under pressure, generation of a crack of the mold is prevented, the mold strength becomes large, and low temperature canting of 400 deg.C can be executed. Since low temperature casting is executed, concentration of a binding material can be increased and the mold strength can be further increased.

Abstract: PURPOSE:To enable the high speed and sure changing of the color of an ink sheet by providing an apparatus with a carrier force transfer means for transferring a carrier force to first and second carrier means and with a switching means selectively intermitted with said first and second carrier means. CONSTITUTION:The driving force of a head motor M3 is transferred via reduction gears 15a, 15b to rotate a head cam 16 and a ribbon cam 17. Said cam 16 performs the ON-OFF control of separation of a recording head 18 from an biasing of said head to a platen 5 and a ribbon direct take-up. The point 29c of a cassette shift lever A29 is pressure-welded to the surface with a low height of the cam surface 17a of said ribbon cam 17 by the energizing force of a cassette shift spring 30 and a carriage table 35 is put in the down position. When the cam 17 is rotated clockwise from said state, the contact point between the cam surface 17a and the point 29c of said lever A29 increases in height vertically to the cam surface so that the lever A29 rotates clockwise over the energizing force of said spring 30. Thus, said table 35 moves upward and when the height of said cam surface 17a reaches a specified position, the lower stage cassette is brought to a working state.
