Abstract: PROBLEM TO BE SOLVED: To enhance utility promotion effect of a preview service. SOLUTION: An inverse quantization circuit 32 multiplies a quantization step a3 obtained from each inverse quantization table connecting to an inverse quantization table selector switch circuit 42 with each pixel of each square area in compressed data f1, to obtain a discrete cosine transform (DCT) coefficient b3 and gives it to an inverse DCT circuit 34.

Title: Preparation of dutch pessary
Inventor: FURUMOTO HITOSHI
IPC: B29C43/18
Filed: 1987-12-25
Abstract: PURPOSE:To prevent the generation of a pinhole and to simplify manufacturing, by using upper and lower molds showing the predetermined shape of a pessary and forming an integrated shape, wherein a spiral ring is sealed in rubber equipped with a tab, by the press molding of rubber. CONSTITUTION:Upper and lower molds 3, 4 are split and weighed unvulcanized rubber B is placed at the top position of the lower mold 4 and a spiral ring 5 is engaged with the engaging round groove 6 at a mouth edge position to be set thereto. When upper and lower molds 3, 4 are set to a press machine to perform press molding, the unvulcanized rubber B of the top position A is pressed to flow in the entire region of the gap 2 between the split molds and formed into a pessary shape to be vulcanized. The rubber flows in the round groove 6 so as to cover the spiral ring 5 to become an integrated shape and the excessive rubber is stored in an unnecessary rubber eacape groove 7. Next, the burr of the unnecessary rubber B' expanding to the split surfaces of the press machine is removed. By this method, a pessary having a uniform film thickness and no pinhole can be prepared inexpensively.

Title: Oil pressure control device for continuously variable transmission
Inventor: SAWAZAKI TOMOO
IPC: F16H61/28
Filed: 1989-12-18
Abstract: PURPOSE:To improve reliability by releasing acting oil while securing line pressure so as to regulate its maximum pressure at the time of operating pressure higher than necessary acting upon the hydraulic cylinder of a driving pulley. CONSTITUTION:When a speed change ratio control valve 85 is rigidly fixed in the fully opened state or the like and the maximum line pressure is going to be led into the hydraulic cylinder 414 of a driving pulley, a relief valve 100 is operated to release oil on the downstream side of the speed change ratio control valve 85 of a line 102 into a tank in order to regulate the maximum pressure acting upon the hydraulic cylinder 414. At this time, on the upstream side of the speed change ratio control valve 85 of the line 102, the line pressure is held to its maximum value at the orifice 85a of the speed change ratio control valve 85, and therefore the specified oil pressure acts upon the hydraulic cylinder 424 of a driven side pulley so as to hold the belt tension of a continuously variable transmission appropriately. Reliability at the abnormal time of hydraulic control can be thus secured desirably.
