Title: Electrode for welding
Inventor: NAKAMURA YOSHIYASU
IPC: B23K9/26
Filed: 1979-06-15
Abstract: PURPOSE: To prevent the swing of a wire during welding by using an electrode of a curved wire insertion hole for the electrode of a welding torch.  
     CONSTITUTION: In a CO 2  gas welding method and other MIG welding methods using a fine diameter wire, the degradation in current collecting effect owing to the swing of a wire occuring in the winding habit, etc. of a reel is prevented by curving the wire insertion hole of the electrode in the torch. For example, the curved electrode having the bend (l 3 ) of a fixed direction and fixed amount at all times is used for the electrode 11 having the insertion hole of a wire 5 in a torch 1. As a result of this, even if there is the bend (l 3 ) at the end of the wire 5, the swing of the wire 5 owing to the rotation and tilting of the torch hardly occurs and this enables the elimination of weld defects. Here, the combination use with a curved type torch 12 is more effective than the straight type torch 1.

Abstract: PURPOSE:To obtain a structure wherein base resistance is decreased, by shortening the distance between the emitter and the base of a bipolar transistor, and enlarging the area of a part where a base electrode is brought into contact with a substrate. CONSTITUTION:On a silicon semiconductor substrate surface, a first protrusion 14 is formed, by using a material except bulk material of the semiconductor substrate. By using the protrusion 14 and a nitride film 15 as masks, a second protrusion 16 is formed in the manner of self alignment. By leaving the nitride film 17 on the side surface of the second protrusion 16, and heat-treating the silicon substrate in an atmosphere containing oxygen, a field oxide film 18 is formed, and the nitride films 15, 17 are eliminated. The second protrusion 16 is made a base region. The bottom part of the first protrusion 14 is made an emitter region. The base region, the emitter region, a base electrode part 27 and an emitter electrode part 28 are all formed in the manner of self alignment. Thereby, a base electrode leading-out part is brought into contact, in an area wider than the conventional area, with a high concentration base region, so that the base resistance is reduced.

Title: Optical coupling device
Inventor: NISHIWAKI SEIJI
IPC: H01S5/00
Filed: 1990-03-26
Abstract: PURPOSE:To easily diminish the spreading of input light and to widen the allowance for errors by providing and optical coupling means before or behind a condensing point by a condensing means. CONSTITUTION:The light emitted from a semiconductor laser 1 is made to the convergent light which has a point F as a convergent point by a condenser lens 2. This light is passed through a polarized light converting element 3 and is thereby polarized to the concentrically and circularly polarized light, the electric field vector of which exists in a concentrical circle tangent direction. The polarized light is then made incident on a circular coupler 5 which has a concentrical circular grating formed on a waveguide layer 4 orthogonal with the optical axis. The coupler 5 is provided before or behind the point F. Since the input light is made into the convergent light or divergent light, the optical coupling means can be provided in the position of sufficiently small spreading of the input light. In addition, the standard deviation of the wave front aberration of the input light is compressed by adjusting a laser beam source or the optical coupling means or condensing means along the optical axis of the laser beam by a sliding means. The deterioration in the coupling efficiency is sufficiently suppressed to small level in this way and the allowance to the errors is widened.

Abstract: PROBLEM TO BE SOLVED: To detect abnormality inside a bearing without being influenced by vibration outside the bearing by arranging an arranging directional groove of a rolling body just under the rolling body, and installing a piezoelectric cable in the groove with a fastening margin. SOLUTION: Among a shaft 1 and a housing 3, the housing 3 becomes a fixing side member, and among bearing rings of a bearing 2, an outer race 6 becomes a fixed side bearing ring. Grooves 7 are arranged on an inside diameter surface of the housing 3 and an outside diameter surface of the outer race 6 to be set just under a ball 8. A piezoelectric cable 9 is installed in the respective grooves 7, and lead wires 10, 10 are pulled out of a pullout groove 11. In the grooves 7, the piezoelectric cable 9 is sandwiched by the outer race 6 and the housing 3 with a required fastening margin. The piezoelectric cable 9 is a piezoelectric element for generating voltage when compressed in the outside diameter direction by applying sheathing of an insulator to the periphery of a copper braided shield by interposing a piezoelectric polymer functioning as a dielectric. A reason for adding the fastening margin is to increase detecting sensitivity by being pressed to the outer race 6 or the housing 3.

Then information proportional to the angle of incident of the solar rays is obtained from the phase shift quantity from the phase shift 15 to calculate the azimuth angle theta.

Title: Caster and image forming device
Inventor: KANDA TAKAHISA
IPC: G03G15/00
Filed: 1997-03-28
Abstract: PROBLEM TO BE SOLVED: To prevent an image forming device from falling down at earthquake and make the moved quantity to minimum by setting the rotational torque value on a caster fixed position in a fixed range. SOLUTION: By anticlockwise rotating a separation/contact means 25, a recessed part 25e is also rotated, it is separated from a projecting part 22c, the space of a wheel holding part 22 is narrowed by the height of the projecting part 22c, and the sides of a wheel and wheel pressing parts 24 are contacted with each other. The contact becomes the rotational load of a wheel 20, and the rotational torque of the wheel 20 on the caster fixed position is set to be 3-10 kgcm. Consequently, rotation of the wheel 20 of a caster at installation is not perfectly locked, some rotational torque is given as caster torque, and hence even if external force in the horizontal direction is added to it by earthquake and the like, just before an image forming device falls down, the wheel begins to rotate so as to make horizontal movement possible.  Further, the horizontally moved distance can be made shift with a little.
