Title: Generation of hydrogen gas and apparatus for generating hydrogen gas
Inventor: YANAI YUSAKU
IPC: B01J23/44
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To simplify or miniaturize the structure of an apparatus and improve the conversion rate of methanol into hydrogen gas by feeding vaporized oxygen and methanol to catalytic beds having the activity for the oxygen raised from the feeding side toward the discharging side and carrying out the catalytic reaction. SOLUTION: Catalytic beds 11 and 12 on the feeding side and the discharging side having the activity for oxygen raised from the feeding side toward the discharging side are filled in the interior of a nearly cylindrical hollow body 7 installed in a reactor 4 and liquid oxygen and liquid methanol are delivered from respective feed sources 1 and 2 through feed pipes 5 and 6, heated in a heater 3 and vaporized. The vaporized oxygen and methanol are then fed from respective orifices 8a and 8b of a feeder 8 into the interior of the hollow body 7, passed through the catalytic beds 11 and 12 on the feeding side and the discharging side and subjected to partial oxidizing reaction. Thereby, hydrogen gas is generated. The vaporized oxygen and methanol are used to continue the catalytic reaction by heat of reaction if the catalytic reaction is once initiated.  As a result, the use of a means for keeping the catalysts warm is not required.

Title: Method of manufacturing cold-rolled steel sheet
Inventor: NISHIURA NOBUO
IPC: B21B13/02
Filed: 1999-07-29
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a cold-steel sheet to make it possible to manufacture a steel sheet with uniform surface properties even during high-speed rolling. SOLUTION: Inlet-side coolant headers 5 of the last stand are arranged on the inlet side away from a roll bite position. A memory 11 decides the upper and lower strip coolant flow rates on the basis of the table stored in accordance with the rolling speed determined from the rotating speed measured with a roll tachometer 12 of the last stand and the target surface roughness of the cold-rolled steel sheet, and sends the signal to a valve opening controller 13. The valve opening controller 13 controls the opening of flow control valves 10a and 10b. The flow rate of the lower strip coolant is made higher than that of the upper side, thereby uniformizing the surface roughness of the upper and lower surfaces of the steel sheet. Since the inlet-side coolant header 5 of the last stand is away from the roll bite, this effect is not lost even during high-speed rolling.

Title: Reproducing device
Inventor: WACHI SHIGEAKI
IPC: G11B20/10
Filed: 1982-12-08
Abstract: PURPOSE:To ensure stable reproduction even at a place where a large number of vibrations are produced with simple constitution by performing a readout operation with the 1st clock signal when the speed variance of a recording medium is larger than a prescribed level after detecting said speed variance. CONSTITUTION:If the interval of a synchronizing signal is shorter than ''289'' in case the synchronizing signal detected at a separating circuit 5 has variance as shown by a figure A for instance, no output of an NAND circuit 41 is obtained any more. Then the output is obtained from an NAND circuit 63 when the interval of the synchronizing signal is longer than ''297''. As a result, a signal which is set at a low potential in a range of intervals ''289''-''297'' of synchronizing signal is extracted from an NAND circuit 66. Reading is possible with a reference clock signal in the above-mentioned range of intervals of synchronizing signal, and it is considered that noises, etc. are generated outside said range. Therefore a switch 113 can be changed over with use of the reference clock signal.

Abstract: PURPOSE: To from images having phases close to each other by realizing the complex conjugation of the electric fields of the images formed out of only the diffracted light rays as an object and forming the auxiliary patterns to be added to the original mask. CONSTITUTION: The diffracted rays 4 generated from the diffraction points at the edges of the mask 3 are guided by a first projecting lens 5 to arrive at the plane of a pupil 6 in a parallel ray state. The secondary light source images which are images that the light sources 2 are subjected to the influence of the diffraction by the mask 3 are formed the plane of the pupil 6 if the transmitted light rays (geometrical rays) from the apertures of the mask 3 are superposed on the above rays. There are the rays to be cut in order for the pupil 6 to be an effective opening and such rays are obtainable by diffraction an scattering. However, the images of the light sources 2 appear on the plane of the pupil 6 and, therefore, that the images of the light sources 2 are cut is equiv. to that the images of the light sources 2 are partly completely adsorbed.  Then, the line-drawing-like images by the patterns on the mask 3 are formed with the diffracted rays 4 from the edges of the mask 3 on the image plane 8 by a second projecting lens 7.

IPC: H01L21/28
Filed: 1994-09-09
Abstract: PURPOSE: To obtain an electrode-buried board in which a material (such as Al or the like) having a property sensitive to an acid can be used for an electrode even when the resistance of a metal material is low. CONSTITUTION: An electrode in an electrode-buried board is constituted in such a way that a metal film 3 composed of a low-resistance material is sandwiched, in the direction of a film thickness, between two protective films 2, 4 composed of a material which is hard to dissolve in an acid. Thereby, when an insulating film is formed selectively by a liquid-phase film-formation method using a solution containing an acid, the metal film which is composed of the low-resistance material is not exposed to the solution, and a low- resistance material whose acid resistance is low can be used as an electrode material.

Abstract: PURPOSE:To ease releasing of a door by bringing into close contact and engaging left and right sides of an operation member and a lever and hereby restricting inclination of the operation member to left and right with respect to the movement direction of the lever. CONSTITUTION:Guides 23a, 23a of a rear end surface of a shaft part 23 are held in an engagement state sliding a front end of the side surface of a lever 19 longitudinally. Accordingly, when a release button 21 is pressed, the release button 21 and the lever 19 are kept in contact at all times via the guides 23a, 23a. For this, the release button 21 is restricted in its inclination to the left and right with respect to the operation direction of the lever 19 and is moved directly rearwardly together with the lever 19. Thus, even when the release button 21 is pressed in a direction displaced from the movement direction of the lever 19 upon a door being opened, the release button 21 is prevented from being inclined and making contact with the circumferential surface of a casing 24 and the shaft part is prevented from being distorted at an insertion port 25 as in the prior art.
