Title: Printer
Inventor: SHIMODA NAOMICHI
IPC: B41J11/42
Filed: 1996-04-16
Abstract: PROBLEM TO BE SOLVED: To realize the stable backward feeding irrespective of the width of paper by a method wherein the width of a continuous form printing paper is confirmed on the basis of the output of a paper width sensor so as to decide a backward feeding speed on the basis of the paper width in order to control the backward feeding speed by the output. SOLUTION: An operation command is dictated from a host computer to a printer main body 1 so as to drive a paper feeding motor 6 and then a tractor 8 in order to feed a continuous form printing paper to a printing position. When an inject signal is inputted, after the width of the continuous form printing paper is detected with a paper width sensor 9, the detected paper width is recognized. After that, the paper width is compared with the regular width set in a printer. When the detected paper width is wider than the regular width, the feeding speed of the continuous form printing paper is set to be the same speed as that in positive direction. When the detected paper width is narrower than the regular width, the feeding speed of the continuous form printing paper is set to be slower than normal and backward feeding is executed.  Accordingly, the stable backward feeding can be realized irrespective of the width of the paper.

IPC: G03G21/20
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To effectively prevent the temperature of an original platen glass from rising by deciding time required for cooling the original platen glass according to the turning-on time of the original illumination lamp of an image read means and setting a stand-by time until a next image forming action is started based on the cooling time. SOLUTION: When a continuous reading copying mode is selected by an operation part 25 and a recording paper is supplied to a resist roller, a DF motor 5d is driven and an original is carried on the original platen glass at a fixed speed. Then, a traveling-read copying action is started. In parallel with this action, an on-signal outputted from an image tip detection sensor 5h is received by a counter 26 so as to start the counting action of a timer. Then, time until the sensor 5h is turned off is measured. The measured on-time of the sensor 5h is fetched in a CPU 21 as the turning-on time of the original illumination lamp 3a. Based on relation between the turning-on time and the required cooling time, the stand-by time before the next copying action is started is decided.

Filed: 1998-04-07
Abstract: PROBLEM TO BE SOLVED: To simplify the production process of an intaglio, realize the low cost intaglio and the employment of chemical treatment is made to be as small as possible by a method wherein a rigid resin intaglio forming layer covers an intaglio printing base so as to form an intaglio image cell by a laser engraving on the intaglio forming layer, and finally a rigid coating is deposited over the whole surface of the intaglio forming layer. SOLUTION: A peel ply 3 is formed on the surface of a base 2 made of copper, aluminum or the like. An intaglio forming layer 4 is formed on this peel ply 3. After the surface of the intaglio forming layer 4 is finished by grinding and successively irradiated with a laser light modulated by image data, a gravure cell 5 is formed on the intaglio forming layer 4. Next, after the gravure cell 5 being deburring-finished, an intaglio 1 is obtained by depositing a rigid coating layer 6 on the gravure cell. As a result, the production process of the intaglio can be simplified and the low cost intaglio can be realized. Thus, a safe and clean plate making process, in which a dry treatment process is employed and only chemical treatments as small as possible are employed, can be realized.

Abstract: PURPOSE:To prolong the service life of a furnace lining by restraining wearing of a brick at the furnace bottom part of a blast furnace. CONSTITUTION:At the time of charging alternately coke and iron source raw material into the furnace from the furnace top part of the blast furnace, a part of the charging quantity of the coke is substituted with lumpy material 12 having >=1.3 apparent sp. gr., >=80wt.% of fixed carbon, <=1wt.% of volatile matter and 30-200mm of grain diameter. The above lumpy material 12 can be charged into the furnace at the same time of charging the coke 13 but it is desirable to charge the lumpy material, separately with the coke 13 concentrically in the furnace center range. By this method, as a part or a large part of the coke deposited layer 25 at the furnace core is constituted with the larger apparent sp. gr. of lumpy material 12 than the coke 13, the float-up of the coke deposited layer at the furnace core is restrained. Further, the liquid permeability of the deposited layer itself is improved and molten iron flowing speeding at the furnace bottom part is lowered and the brick wearing of the furnace bottom part 19 and the side wall 20 can be restrained.

Title: Microbial preparation of cyanoacetic acid
Inventor: NAKAHAMA TETSUROU
IPC: C12P13/00
Filed: 1979-07-27
Abstract: PURPOSE: To prepare cyanoacetic acid in high yield, by culturing a specific microorganism in a medium containing ethylene cyanhydrin as a major carbon source, and separating and recovering the accumulated cyanoacetic acid from the medium.  
     CONSTITUTION: A microorganism selected from Pichia, Brethanomyces, Coryne- bacterium, and Nocardia genus is cultured in a medium containing ethylene cyanhydrin as a major carbon source, a nitrogen source, an inorganic salt, a small amount of glucose, molasses, etc. at 20W40°C for 2W7 days under aeration and agitation or shaking. When the pH of the medium is lowered during the culturing, it is controlled to 7W8 by adding CaCO 3 , etc. thereby converting the produced cyanoacetic acid as calcium salt. By this procedure, a large amount of the cyanoacetic acid can be accumulated in the medium in high efficiency. After the completion of the culturing, the liquid is centrifuged, and the separated liquid is extracted with ether. The objective cyanoacetic acid can be obtained by distilling out the ether from the extract. As an alternative method, the separated liquid is contacted with an anion exchange resin, and the adsorbed cyanoacetic acid is eluted and dried. The microbial cells may be immobilized with acrylamide resin, etc.

Abstract: PURPOSE:To prevent the electrification of the insulator substrate of a thin-film transistor(TFTR) array, etc., and the attraction of foreign matter in a production stage and to improve a yield by forming high-resistance conductive films between the insulator substrate and transistors. CONSTITUTION:A tin oxide film 2 is deposited on the glass substrate 1 which is an insulator and thereafter, the TFTRs are formed on the glass substrate 1. While the entire part of the substrate 1 is preferably coated with the high-resistance film in order to prevent the electrification of the substrate 1, the pickup of the dust on the parts where the TRs, etc., are not mounted at all is of no problem and, therefore, at least the parts to be mounted with the TRs, etc., of the substrate 1 are simply necessitated to be coated with the high-resistance films. The transparent films are obtainable if the conductive films produced of tin oxide or by mixing indium with the tin oxide, etc., are used as the high-resistance conductive films. The substrate transparent as a whole is obtd. if the insulator substrate is transparent and the high- resistance conductive films are transparent as well. Such substrate is effective for liquid crystal displays, image sensors, etc.
