Abstract: PURPOSE:To prevent the deterioration of a printed character or the generation of background fog by a solvent, by containing a color forming agent, a coupler and a modified polyvinyl alcohol resin based on a salt of a butylated vinyl alcohol/maleic acid copolymer. CONSTITUTION:A modified polyvinyl alcohol resin is a resin based on a salt of a butylated vinyl alcohol/maleic acid copolymer and synthesized by butylating the vinyl alcohol/maleic acid copolymer, which is obtained by the hydrolysis of a vinyl acetate/maleic anhydride copolymer, through the dehydration reaction with butylaldehyde. With respect to the combination of a color forming agent and a coupler contained in a recording layer, a combination such that both of them are contacted under heating to generate color forming reaction, for example, a combination of a colorless or light colored basic dye and an acidic substance or a combination of a metal salt of higher fatty acid such as ferric stearate and phenols such as gallic acid is designated. This resin coating solution is prepared as an aqueous one and applied to a thermal recording layer.

Inventor: TANI YOSHIKI
IPC: C12P35/00
Filed: 1993-08-26
Abstract: PURPOSE:To obtain a deacetylcephalosporanic acid derivative useful as a production intermediate for a cephalosporanic acid-type antibiotic substance in high conversion by reacting a cephalosporanic acid derivative with a microorganism of the genus Rhodotorula under specific condition. CONSTITUTION:A cephalosporanic acid derivative of the formula (R is H, an R<1>-CO or an R<2>-SO2; R<1> is H, amino, etc.; R<2> is a 1-3C alkyl, etc.) is reacted with a microorganism of the genus Rhodotorula such as Rhodotorula glutinis 38B1 (FERM P-13039). The conversion activity against a deacetylcephalosporanic acid derivative corresponding to the cephalosporanic acid derivative of the formula can be improved by culturing the microorganism of the genus Rhodotorula in the presence of a fatty acid ester compound. The cephalosporanic acid derivative may be reacted with processed materials of the microorganisms in place of the microorganism itself.

Filed: 1994-08-31
Abstract: PURPOSE: To improve coding efficiency by measuring generated bit quantity at a 1st coding processing to select an optimum filter coefficient based thereon and using the filter at a second time to provide the output of a bit stream. CONSTITUTION: In the 1st coding processing, an encoder 18 does not use a pre-filter 19 to allow a storage device 20 to store generated bit quantity for each frame. A coefficient decision circuit 21 selects an optimum filter coefficient among plural filter coefficients designed in advance based on a coding bit rate and the generated bit quantity and set the optimum filter coefficient to the pre-filter 19. In the case of the second coding processing as to the same frame, a moving image signal processed by the pre-filter 19 is given to the encoder 18 in which coding processing is applied to the signal to provide the output of a bit stream.  The assigned bit quantity per frame is decided based on a coded it rate and the frame rate and the filter coefficient is selected so that the frequency pass band of the pre-filter 19 is made narrower as the generated bit quantity is larger accordingly.

IPC: B21C29/00
Filed: 1994-08-31
Abstract: PURPOSE: To enable extrusion with a high extruding ratio, in heating a billet on a magnetic flux convergent element by means of a vertical induction heating furnace, by interposing a metallic piece preheated to a temperature higher than that of the billet and to reduce the initial extruding load. CONSTITUTION: A metallic piece 4 is preheated while a billet 1 is preheated. The metallic piece 4 is placed on a magnetic flux convergent element 3 with the billet 1 placed over the piece, and both the billet 1 and the metallic piece 4 are preheated by a vertical induction heating furnace 2. In the stage of starting the heating, the temp. of the metallic piece 4 is made higher than that of the billet 1 by 50 deg.C or above. After the heating, only the billet 1 is provided for extrusion, and the metallic piece 4 is used repeatedly. The action of the metallic piece 4 prevents the billet 1 from being unheated. Another action of the metallic piece 4 is heap up of the billet 1. Thus, even if the billet is a hard- to-work material and also has a long heating time, the initial extruding load is reduced, and working is performed with a high extruding ratio.
