Title: Dynamic image coding method, dynamic image decoding method, dynamic image recording medium and dynamic image coder
Inventor: SUZUKI TERUHIKO
IPC: H04N19/86
Filed: 1993-12-15
Abstract: PURPOSE:To minimize the reduction in information representing a picture fine pattern while reducing noise even at a signal band with a bad S/N by applying quantization to a picture signal at a signal band whose S/N is deteriorated through coding in the preprocessing based on a nonlinear characteristic and then coding the resulting signal. CONSTITUTION:The coder is provided with a nonlinear quantization circuit (NLQ) 70 and a nonlinear inverse quantization circuit (NLIQ) 71. In the case that a moving picture signal is coded by using a predetermined prediction picture signal, a prescribed arithmetic operation is applied to the coded signal, the signal obtained through the arithmetic operation is quantized and the quantized signal is subjected to variable length coding, then the picture signal at a band where the S/N of the picture signal is deteriorated is quantized based on its nonlinear characteristic to emphasize the signal at the band. Furthermore, in a decoder, a decoding signal is inversely quantized based on a nonlinear characteristic reverse to that of the coder and demodulated. Thus, even when it is difficult to distinguish a picture fine pattern from picture distortion, the reduction in a level of the pattern in existence on a flat level portion of the picture signal is suppressed.

Abstract: PROBLEM TO BE SOLVED: To enable a tube opening/closing clamp to be freely moved on a tube and prevented from its careless movement thereon by providing the first hooking part for fixing the clamp on the tube and the second hooking part for closing the tube. SOLUTION: The way of holding a tube 7 by a clamp is carried out in such a way that an erection part is warped around a bent part 5 serving as a fulcrum by pressing the clamp on its both sides by fingers, a projecting part 91 slips in the firs groove part 93 from the other end part tip end and when fingers are released from the projection piece 2, the projecting part 91 hits the start part of the groove part 93 and is hooked there so that a tube pressing member 6 can hold the tube 7. In order to block the tube, if the clamp is further pressed and a hooking end 92 is hooked below the eaves of an eaves-like part 96, small projecting parts 3 themselves bite each other so as to block the tube 7. Therefore, when the hooking is released, the clamp can be moved freely on the tube but if the first hooking part is hooked, careless movement of the clamp on the tube may not take place.
