Title: Method and device for deforming image
Inventor: IIJIMA TATSUYA
IPC: G06T13/80
Filed: 1993-12-22
Abstract: PURPOSE:To provide an image deforming method/device by which the picture of a bit array system can be freely and smoothly deformed with less memory capacity. CONSTITUTION:When the apex (moving reference grid points (0, q)) of an arbitrary small polygon on the outer frame of a deformed object is moved to an arbitrary position which constitute the outer frame again at least after deformation, the apex of the other small polygon is moved so that the whole deformed object is smoothly deformed. The apex of the other moved small polygon is calculated based on the moved apex (deformed moving grid point (xd, yd)) of the arbitrary small polygon. Then, the forms of the respective deformed small polygons are decided in accordance with the respective calculated apexes. An original image is sequentially deformed so that it corresponds to data of the deformed small polygon so as to generate the whole deformed image.

Title: Preparation of water-curable inorganic molded product
Inventor: OKIMURA YOICHIRO
IPC: B28B1/14
Filed: 1992-12-28
Abstract: PURPOSE:To ensure that no water drain hole trace remains on the surface of a molded product and the frequency of replacing a filter medium is decreased by using wire netting with rigidity which doe not allow part of the netting as a filter medium to be aspirated into a water drain hole side during the suction stage of the filter medium. CONSTITUTION:A bottom force 3 as a first split die which consists of two metal nettings 1, 2 stacked on the surface of the die and a top force 4 as a second split die are closed together. Next, a molding material is injected into a die cavity 5, and at the same time, a vacuum pump is activated to exhaust air from an exhaust pipe 31 so that an air pressure in an air chamber 33 is decompressed to about -650mmHg. Consequently, surplus moisture is removed from the molding material injected into the die cavity 5 through the water drain hole 32 and the wire nettings 2, 1. After adequate dehydration, the vacuum pump is stopped, and the top force 4 and the bottom force 3 are opened to take out a molded product from the die. Further, this molded product is cured and hardened to obtained a finished molding. The molding thus obtained shows no projecting part due to the water drain hole 32 on the surface at all. Therefore, part of the filter medium no longer enters into the water drain hole when the filter medium aspirates to dehydrate water.

Inventor: SHIBANO HIROAKI
IPC: B29L23/00
Filed: 1996-12-26
Abstract: PROBLEM TO BE SOLVED: To give a mandrel high slip properties and make it possible to retain the slip properties of the mandrel for a long time, if it is used a plural number of times by using silicone which is scientifically bonded to at least, another resin component.
