Title: Fuel ceil stack
Inventor: SHIROKURA KENICHI
IPC: H01M8/02
Filed: 1985-11-08
Abstract: PURPOSE:To uniformize the surface pressure applied to each of unit cells, by letting the density on the four corners of separators lower than that in the center portions. CONSTITUTION:In a fuel cell stack having a plurality of unit cells 2 piled with intervening separators 1 together with a cooler for cooling the piled unit cells, and clamped with clamp metal fittings 3, 4 provided on their top and bottom, the density on the four corners of the separators are made to be lower than that in the center portions. As a result, when the separators 1 are clamped, the thickness on the four corners become smaller than that in the center portions. Therefore, pressure is applied to the center portions of the unit cells 2 at first, and then the pressure is gradually applied to the edge portions, so that the pressure can be applied while compensating deflection and shear generat ed when the unit cells 2 are piled and clamped, resulting in uniformizing the surface pressure applied to each of the unit cells 2. And since the surface pres sure becomes uniform, the contact resistance between the unit cells 2 is de creased and the cell performance is enhanced.

Title: Manufacture of semiconductor storage device
Inventor: KUNITO MASAO
IPC: H01L21/8246
Filed: 1996-08-30
Abstract: PROBLEM TO BE SOLVED: To prevent the minimum channel length from becoming shorter and, at the same time, to improve the alignment accuracy of a photoresist used at the time of writing data by forming a buried diffusion layer by introducing an impurity with energy sufficient to make the impurity reach a semiconductor substrate through an interlayer film after forming the interlayer film. SOLUTION: After an interlayer film 11 is formed, a buried diffusion layer 13 is formed by introducing an impurity with energy sufficient to make the impurity reach a semiconductor substrate 1 through the interlayer film 11, so as to suppress and reduce the thermal diffusion of the impurity. For example, the buried N<+> -type diffusion layer 13 is formed by introducing arsenic to a memory cell area 4 and a caliper area 5 with energy sufficient to make the arsenic pass through the interlayer film 11, a tungsten silicide film 10, and a polycrystalline silicon film 9 by using a photoresist 12 on the interlayer film 11 as a mask. Thereafter, data are written from the surface of an interlayer film 16 by using a photoresist as a mask. Data writing is performed by having code P-type injection layer formed by introducing boron.

Title: Disk loader
Inventor: KAMEMURA TAKESHI
IPC: G11B17/056
Filed: 1992-09-18
Abstract: PURPOSE:To correctly chuck a disk and to reduce the thickness of a reproducing device by positioning a boss in the center of a turntable to fit a cylindrical part of a chucking disk. CONSTITUTION:A slider 7 is moved in accordance with an advance of loading to turn and lift a subchassis 3. By this lifting, the disk D on a tray 5 is raised by the turntable 26, and is chucked between the turntable and the chucking disk 83. When a base chassis 2 under lifting is shifted in its position to the side of the slider 7, i.e., in the forward direction in the midst of the movement of the slider 7, an abutting part 201 on the chassis 2 is pressed by a cam piece 701 of the slider 7 to push back the chassis 2 to its proper position, so that the boss 261 in the center of the turntable 26 is positioned to fit the cylindrical part 831 of the disk 83, so as to chuck the disk D accurately. Consequently, it is not necessary to increase the overall height of the table 26 and the disk 83, and hence the reproducing device can be reduced in thickness.

Title: Sliding bearing for driving head
Inventor: HASHIMOTO YOICHI
IPC: G11B21/02
Filed: 1990-09-21
Abstract: PURPOSE:To cancel the deviation of sliding resistance, and to make the transit time of a head uniform irrespective of its moving direction by lengthening distance between the position of the center of gravity of the head of an object to be driven and the central position of a sliding bearing toward a proper direction and by the proper distance. CONSTITUTION:When a sizing shaft is made to penetrate oil impregnated bearings 17, 18 like to rub their inner surfaces, the inner surfaces of the oil impregnated bearings 17, 18 are squashed by the sizing shaft 20 as they are rubbed, and are turned into finished size. At that time, the powder particles of the inner surfaces 19 of the oil impregnated bearings 17, 18 are squashed so as to be inclined toward the drawing direction of the sizing shaft 20, and are turned wedge-shaped, and the deviation is always caused in the sliding resistance of the oil impregnated bearings 17, 18 according to the moving direction. In order to make this deviation uniform, load to be applied to both the ends of the sliding bearing is made uneven by shifting the center of gravity of the head of the object to be driven and the center of the sliding bearing. Thus, the deviation of the sliding resistance due to the moving direction of the head can be prevented from being caused.

Since the tracks 5, 6 are installed being offset by 180 deg. and they form a circular track when the centrifugal forces of the weights 1, 2 cross each other between the bowl-like disks A, B.
