Title: Gas-diffusing electrode for fuel cell
Inventor: TAJIMA HIROYUKI
IPC: H01M4/86
Filed: 1983-09-30
Abstract: PURPOSE:To achieve both high water repellent property and gas diffusion by enabling a great amount of fluorine resin to be used in a water repellent layer by impregnating an electrode base material with two kinds of fluorine resins having different melting points before the thus obtained body is sintered at a temperature corresponding to the melting point of the low melting fluorine resin. CONSTITUTION:After an electrode base material 1 is impregnated with two kinds of fluorine resins 5 and 6 having different melting points, the thus obtained body is sintered at a temperature of around 290 deg.C at which the low melting fluorine resin 6 melts. As a result, the high melting fluorine resin 5 remains unmolten in the electrode base material 1 and only the low melting fluorine resin 6 melts and is solidified thereby being attached to carbon fiber 1 and the high melting fluorine resin 5, thereby enabling the area (A) to be made water repellent. Furthermore, proper spaces are formed in the electrode base material 1 due to the high melting fluorine resin 5 remaining unmolten in the material 1, thereby achieving a good gas permeability while maintaining a high water repellent property.

Filed: 1986-08-05
Abstract: PURPOSE:To enable the title equipment to perform a heating processing and cooling processing continuously, by a method wherein a pressurizing fluid for heating and that for cooling are circulated separately from each other by dividing the pressure chamber into two chambers or more. CONSTITUTION:A thin 3 to be compressed is placed between endless steel belts 2 and the same is pressurized and processed while the same is being conveyed. In other words, pressurizing fluids 6a, 6b poured within pressure chambers 4a, 4b pressurize endless steel belt 2 at uniform surface pressure while circulating within the pressure chambers 4a, 4b as shown by an arrow. Then the thing 3 to be compressed is pressurized at uniform surface pressure by this force. Then the thing 3 to be compressed is heated or cooled by a temperature difference among the pressurizing fluids 6a, 6b and endless steel belt 2. In other words,the thing 3 to be compressed is heated at the time when the same passes through the pressure chamber 4a and the same is cooled at the time when same passes through the pressure chamber 4b. With this construction, in the case where, for example, laminate processing is performed, the thing 3 to be compressed is heated and fused at a position of the pressure chamber 4a and then the same is cooled and molded at a position of the pressure chamber 4b.

Title: Method and device for cooling device charged into vacuum refining vessel
Inventor: AIZAWA KANJI
IPC: F27D17/00
Filed: 1993-07-26
Abstract: PURPOSE:To prevent the lowering of capacity in a vacuum evacuating device and the lowering of vacuum degree in a vessel by again returning exhaust gas to the vacuum vessel after cooling and dust-removing the exhaust gas from the vacuum vessel to use to the cooling of a nozzle opening/closing driving device in a ladle, at the time of cooling the nozzle opening/closing driving device of the ladle during vacuum refining. CONSTITUTION:At the time of executing the vacuum refining by charging the ladle incorporating molten steel in a vacuum vessel 1, the necessary quantity to cool device, such as the nozzle opening/closing device in the ladle is extracted from the exhaust gas 8 generated accompanied by the refining. After treating the exhaust gas with an exhaust gas cooling device 14 and an exhaust gas dust collector 13, the necessary pressure is given with a booster 12. This treated exhaust gas is returned to the vacuum vessel 1 as cooling gas 9 and circulated so as to cool the part 18 to be cooled. The lowering of the capacity in the evacuating system and the lowering of the vacuum degree in the vacuum vessel can be prevented, because the exhaust gas is used to the cooling medium without pouring the special cooling gas.

Title: Correcting method of positioning in motorized injection molder
Inventor: TAIRA TAKAYUKI
IPC: B29C45/66
Filed: 1991-06-28
Abstract: PURPOSE:To eliminate the waste of electric power by a method wherein a toggle is locked up by driving a servo motor to its command position so as to maintain pressing force between a movable member and a fixed member at mechanical stability point and, at the same time, the load of the servo motor in lockup is detected so as to control the command position in order to bring the load into the set range. CONSTITUTION:During lockup, load acting to a mold clamping servo motor 7 is detected. By increasing or decreasing the value of the rotation of a crank 2 through the increase and decrease of the position command value of the servo motor 7 to the direction to decrease the detected value, the center of rotation Q1 of the crank 2 is aligned with both the ends Q2 and Q3 of a link 3 so as to establish lockup state. Thus, the turning moment by the reaction of mold clamping is removed from the center of rotation Q1, resulting in allowing to maintain the reaction of mold clamping during the lockup state without giving driving torque to the servo motor 7, and in preventing electric power from wasting and the servo motor 7 from overheating and, at the same time, making facilities such as stopper and the like unnecessary.

Title: Apparatus and method for processing image
Inventor: YOKOSE TARO
IPC: G06T11/60
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To overwrite images inexpensively and at high speed. SOLUTION: An image input part 10 sequentially inputs partial images of an image. An overwrite process part 20 takes out a corresponding partial image (partial image not coded) from a compression page memory 60, overwrites the input partial image to the partial image and stores in a small area buffer 30. A process estimation part 90 analyzes a plurality of images to be overwritten and estimates whether or not the overwritten partial image is to be further overwritten. When the overwritten partial image is judged to be overwritten, the partial image is coded at a coding part 50 and updated, written in the compression page memory 60. On the other hand, when the image is judged to be not to be overwritten, the partial image is updated, written in the compression page memory 60 without being coded.  At a time point when all partial images of all images are completely processed, images completely overwritten are stored in the compression page memory 60 in a state in which the images are coded.
