IPC: H04N1/393
Filed: 1993-10-20
Abstract: PURPOSE:To perform reducing/enlarging transformation processing in a short time even without performing any complicated processing by a software by successively displaying divided images provided by thinning and selecting pixel data on the same screen in a time-division manner. CONSTITUTION:The starting point of thinning processing (reduction processing) to an image (A) composed of 16 pixels is changed into pixel numbers 11, 12, 22 and 21, four ways of reduced images (B)-(E) are provided, and the provided four images are successively displayed in a time-division manner. Therefore, when the provided four pictures are successively exchanged, those pictures look like an OR processed image because of the after image phenomenon of human eyes. On the other hand, when the pictures are exchanged at suitable time intervals, a picture similar to display provided by a gradation system can be provided although there is a little flicker in the picture. This can be applied not only to the image reducing transformation processing but also to the image enlarging transformation processing. Thus, the image reducing/ enlarging transformation processing can be easily performed without depending on any complicated arithmetic processing.

Abstract: PURPOSE:To increase the content of a high critical current density phase which is not melted even when the sintering temp. is increased above 800 deg.C by mixing powdery raw materials to obtain raw powder, forming the raw powder, and sintering the formed product in an oxygen atmosphere at a specified temp. CONSTITUTION:The 99.9%-purity powders of Bi2O3, SrCO3, CaCO3, CuO, and PbO, for example, are mixed at Bi:Pb:Sr:Ca:Cu=0.7:0.3:1:1:1.8 to obtain raw powder. The raw powder is dispersed in ethanol, and mixed for 100hr by a ball mill. The mixture is dried and then added with a PVB binder, redried, and press-formed at 3ton/cm<2> pressure to obtain a formed product having 68% relative density. The formed product is then sintered at 857 deg.C for 100hr. Since the relative density of the formed product is increased to 68% in this way, the whole product is not melted even when the sintering temp. is increased above 800 deg.C, and the volume percentage of the high critical current phase is increased.
