Title: Casting mold for slip casting
Inventor: IWATANI NOBUO
IPC: B28B1/26
Filed: 1988-06-15
Abstract: PURPOSE:To obtain a casting mold for slip casting, by which the productivity of casting is improved and which has a long service life, by a method wherein a casting mold matrix consisting of thermosetting resin is interspersed with low-melting acicular metal and, after that, heated up to a temperature higher than the melting point of the metal so as to remove the metal from the matrix in order to form many continuous pores in the casting mold matrix. CONSTITUTION:Liquid uncured epoxy resin as chief material, curing agent to cure the chief material and low-melting alloy (alloy of 50% of Bi, 26.7% of Pb, 13.3% of Sn and 10% of Cd having the melting point of 70 deg.C), are prepared. Under the condition that the chief material is held at a temperature slightly higher than 70 deg.C, the alloy under molten state is mixed into the chief material. By adding the curing agent, the epoxy resin is cured while agitating. By immersing the resultant cured body in hot water having a temperature of 70 deg.C or higher in order to melt the alloy so as to remove the molten alloy from a casting mold matrix by suction or pressing, the removed impressions are made into fine continuous pores 3 so as to produce a casting mold. Since many continuous acicular pores are formed all over the whole casting mold, the drying of the mold after every finish of casting becomes unnecessary.

Filed: 1990-06-05
Abstract: PURPOSE:To drastically shorten the average renewal time of a screen by using a matrix type bistable display panel and rewriting a display after impressing a prescribed voltage only on an image which must be rewritten. CONSTITUTION:A display data generated by a CPU, etc., is stored in a data memory 20, and in accordance with a display mode, in the case of partial scanning, a renewal data is extracted by a comparison circuit 23 so as to read out the data necessary for a data control circuit 24 from the memory. The writing and the reading out of the data memory 20 are controlled by a memory control circuit 22, and a scanning driver 26 and a signal driver 27 are controlled by a driver control circuit 25 in synchronism with the read-out timing so as to scan only a scanning electrode which needs rewriting. On the other hand, in the case that the display mode displays complete scanning, the data in the data memory 20 is successively read out, and the display panel 28 is completely scanned so as to renew the screen. Thus, the display with high uniformity can be always maintained because of using a partial scanning method and a complete scanning method jointly in this way.
