Abstract: PURPOSE:To part easily forming goods, to reduce a distortion of the forming goods, and to increase a forming draft by forming a gap by which the outside edge part of a plate to be formed can be inserted into a female metallic die without pressure, in a forming metallic die of a superplastic metallic plate by a fluid pressure. CONSTITUTION:A female die 11 having a product die recessed part 12, and an opposed metallic die 13 having a feed port 14 of a pressurized fluid are combined by each clamp part 15, 16. A circumferential groove part 17 is formed in the circumferential edge of the recessed part 12, and the circumferential part 17 has a gap by which the outside edge part of a plate to be formed 18 can be inserted without pressure. That is to say, this gap has a size of at least a thickness of the plate 18. Accordingly, the plate 18 can be formed freely without being restricted by the metallic die. Also, the plate 18 and the female die 11 are made to adhere tightly to each other by a fluid pressure at the time of forming, therefore, it is not feared that a fluid leaks. However, if said gap is excessive, said fluid leakage is apt to occur, and a function for suppressing wrinkles cannot be fulfilled, therefore, an air-gap in case when the plate 18 has been inserted into the circumferential groove part 17 is set to a prescribed range.

Title: Image processing unit
Inventor: HONMA TOSHIMITSU
IPC: H04N1/415
Filed: 1994-09-19
Abstract: PURPOSE: To eliminate or reduce distortion caused by image compression processing by applying revise processing to part of a coefficient obtained through discrete cosine transformation in the unit of divided blocks of an image into a desired value. CONSTITUTION: When a correction request is made as to an area designated by the operator in an image subjected to edit processing and before compression, a CPU 2 uses a block correction processing function 2c to make correction processing. In this correction processing, a picture element subjected to distortion correction is obtained by the processing subtracting a vector (g) obtained by inverse DCT to an original image vector including an allowable error from a vector (y) of image data. The CPU 2 replaces the picture element of an object block with a corrected picture element and applies compression processing for storage or transmission. The distortion between a block area and an adjacent image area is eliminated or suppressed into a permissible error by revising part of coefficients obtained by applying DCT to a block having the distortion.

Title: Drum type centrifugal dehydration device
Inventor: TAMURA KIYONORI
IPC: D06F49/00
Filed: 1998-08-06
Abstract: PROBLEM TO BE SOLVED: To prevent abnormal vibration at the time of dehydration even in the case of housing various kinds of laundry inside a drum. SOLUTION: After the end of washing and intermediate dehydration, the amount of the laundry inside the drum 3 is detected and a balance adjustment water level corresponding to the amount is decided. Then, after final rinsing is ended, water is discharged until a water level inside an outer tank 2 becomes the balance adjustment water level and the drum 3 is rotated at a rotation speed at which centrifugal force acting on the laundry inside the drum 3 is slightly larger than gravity in a state of accumulating the appropriate amount of the water at the bottom part of the drum 3. The laundry is stuck to the inner peripheral wall surface of the drum 3, rotated, brought into contact with the water at the time of passing through the bottom part of the drum 3 and made to absorb the water.  Thus, since any laundry sufficiently contains the water when balance adjustment is performed so as to reduce an eccentric amount in the state, the influence of the dispersion of weight reduction by the dehydration is relatively reduced and unbalance accompanying dehydration progress is reduced.
