Title: Method of making casting mould
Inventor: HANAZAKI KOUICHI
IPC: B22C1/26
Filed: 1979-08-28
Abstract: PURPOSE: To improve remarkably a hardening rate of a casting mould by heating and hardening a sand mould drawn from a metal mould with microwave, after castng sands which contain water soluble paste as a binder are charged into a heated metal mould and the surface of the sand mould is hardened.  
     CONSTITUTION: Casting sands of which binder is water soluble paste, such as natural paste, compound paste, water resin emulsion and water soluble phenol resin, are charged into a heated metal mould. Thus, a sand mould is heated successively from the portion in contact with the metal mould and the mould surface is hardened, and, several ten seconds after charged into the metal mould, the sand mould can have an enough strength to draw out therefrom. When the sand mould drawn out from the metal mould is radiated with microwave, the nonhardened portion in the center thereof is heated rapidly and water is vapourized and released, so that the sand mould is dryed and hardened.

Abstract: PURPOSE:To speed up operation by providing a zero detection circuit so as to detect the zero of a partial remainder, and resetting a flag. CONSTITUTION:A logical operation device 3 subtracts a divisor register 2 from the reading of a dividend register 1, and stores the result in a partial remainder register 4. At such a time, the carry bit of said register 4 is decided either '0' or '1', and if it is '0', an operation result register 5 is shifted left by one bit, and '1' is transmitted to a bit G in the logical operation register 5. If the carry bit is '1', said register 5 is shifted left by one bit, and '1' is transmitted to the bit G. Then, the contents of the partial remainder register 4 is shifted left by one bit, and transferred to the dividend register 1, and the next operation of the dividend and the divisor is made a subtraction. If the dividend is exactly divisible upon the completion or in the middle of operation, an OR gate 6 connected to the partial remainder register 4 detects that the partial remainder is zero, and a bit S initialized to '1' by an FF 7 is reset to '0', whereby that the dividend is divisible is shown.
