Abstract: PURPOSE: To fabricate a hollow core of even complicated external shape easily and speedily, by forming the casting sand containing moisture being charged in the inside of a hollow core borer rotating around the shaft center in the form of a hollow core by centrifugal force, and freezing and solidifying in this state.  
     CONSTITUTION: Casting sand 14 containing moisture is charged 13 into a rotating hollow core borer 8, and is formed in a hollow core shape by centrifugal force, and is frozen and solidified in this state. This formed and solidified core is taken out, and presented for use as the core for castings. As the freezing method, for instance, the inside of the core borer 8 is filled with coolant such as liquid N 2  and liquid CO 2 . By this method, a frozen core suited to any complicated internal shape of the core borer and having an external shape of uniform filling may be easily and speedily fabricated by using centrifugal force.

Title: Video signal encoding method
Inventor: TAWARA KATSUMI
IPC: H04N19/65
Filed: 1990-02-26
Abstract: PURPOSE:To converge a quantization step size to an optimum value in response to a change in the picture by decreasing the quantization step size more than a preceding frame quantization step size when a power of a picture data obtained by the inter-frame coding. CONSTITUTION:A quantization control unit 36 decreases a quantization step size QNT to a 1/2 of a preceding frame-quantization step size PQNT used in the preceding frame when a macro block power MBP obtained by the inter- frame coding is smaller than a prescribed threshold level. Then the quantization control unit discriminates whether or not the preset QNT is smaller than the lower limit 1. When smaller, the QNT is set again to the lower limit 1. When the QNT is not smaller than 1, the value is set as the QNT without resetting. When a picture with less movement is sent, the quantization control unit 36 applies table quantization processing while the quantization step size QNT is converged to the lower limit.
