Title: Manufacture of welded steel pipe with uneven thickness
Inventor: FUKADA YASUTO
IPC: B21D5/10
Filed: 1982-06-16
Abstract: PURPOSE:To obtain an uneven-thickness welded steel pipe which has no variation in internal diameter at low cost by bending a blank material steel plate with uneven thickness whose one surface is flat in a U and then an O shape, and expanding the pipe after seam welding. CONSTITUTION:The blank material steel plate 1 which has a beltlike thick part 2 partially in the lengthwise direction and a flat surface as the other surface is formed. Both edge parts of this blank material steel plate are bent toward a flat end surface which becomes an internal pipe surface after the work and then bent in a channel shape. This work 11 is formed into an open seam pipe 12, which is pressed externally with dies. The open seam part is welded temporarily and then welded principally, and the pipe is increased in diameter by an expander, etc. This method improves the workability and reliability of the uneven- thickness welded steel pipe.

Title: Lead material for semiconductor
Inventor: FUTATSUKA RENSEI
IPC: H01L23/48
Filed: 1978-08-29
Abstract: PURPOSE: To eliminate peeling due to oxidation in the lead material made of Cu with a heat resistibility and a softness by adding one or more kinds of Al, Mn and Si in an amount of 0.005W0.2% by weight with P exceeding no more than the content of unavoidalbe impurities.  
     CONSTITUTION: One or more kinds of Al, Mn and Si in an amount of 0.005W 0.2% by weight is added to a Cu lead material containing small amount of Ag, provided that P contained exceeds no more than the content of unavoidable impurities. Raw material with such a composition is cast into an ingot in a proper size which is cut on the both surfaces after a hot rolling. Then following repetition of cold rolling, medium annealling, and pickling, it is cold rolled to the final thickness to make a lead material. In this manner, after it is heated up to 450°C for 15 minutes and cooled down to a normal temperature, a bending test shows that the rate of peeling can be reduced to zero, negligible if any.

Abstract: PURPOSE: To provide an endosope having a longitudinal groove which accepts a channel of a disposable sheath and a uniform control characteristic in all directions, by connecting a braided tube to a D-shaped cylindrical part and by forming a longitudinal groove on the opposite side in the diameter direction to the D-shaped tube in the braided tube. CONSTITUTION: An optical part of an endoscope illustrated as a pair of aligned optical fiber 90 and a lighting optical fiber 92 extends through a D-shaped flexible tube 94. The D-shaped tube 94 is placed inside a lower part of a braided wire or a meesh tube 120. A slender groove 122 is formed in the upper part of the braided tube 120, and the tube 120 is coated with an appropriate polymer coating 124 so as to seal the braided tube against moisture and to adjust flexibility of the endoscope. The bottom of the groove 122 contacts with an upper surface of the D-shape tube 94. Tubes 134-140 stabilize the shapes of the endoscope and the groove 122 against bending (the vertical direction in the figure) of the endoscope in the plane of the groove 122.  The D-shaped tube 94 stabilizes the shapes of the endoscope and the groove 122 against bending in the transverse direction to the plane of the groove.

Title: Light isolator
Inventor: KUWABARA HIDEO
IPC: G02B6/00
Filed: 1978-08-29
Abstract: PURPOSE:To branch light only when it is the input light from the specified direction and enable transmission defining to be accuraly accomplished by so forming the isolator that it has an optical guide and the optical guide branched from this and the branch optical guide is absorbed. CONSTITUTION:The first optical guide 1 and the second optical guide 2 (called branch optical guide) branched from this are provided. The left of the optical guide 1 is the input end P1 and the right the output end P2. One end of the branch optical guide 2 is the non-reflecting absorption end P3 which takes matching of refractive indices so as not to allow light to reflect. The light entering from the input end P1 is mostly fetched out to the output end P2 and the loss of light power is small. The light entering from output end P2 is branched to the input end P1 and absorption end P3 and its conversion to radiation mode is large and the light power obtainable at the input end P1 is less than 1/2 the initial one. Namely, with this structure the losses are low in the transmission direction of light and are high in the opposite direction and therefore the transmission defining as an isolator is accurately accomplished.

Abstract: PROBLEM TO BE SOLVED: To easily pass through an article by providing a projection for reducing the frictions of an upper surface and the article passed through while being in contact with the upper surface on the upper surface of a reader provided with a read window. SOLUTION: In a bar code reader 1, on a bottom surface 81 provided with a bottom window 5, the projections 82 whose cross sectional shape is triangular are provided. By reducing the contact area of the article and the bottom surface 81, the friction of the article and the bottom surface 81 is reduced. The extending direction of the projections 82 matches the passing direction of the article and the projections 82 are formed by resin molding together with the bottom surface 81. Also, a member for forming the projections 82 can be stuck to the bottom surface 81. At a part 83 corresponding to an optimum read position, the interval of arranging the projections 82 is narrowed. On the other hand, at the part 84 deviating from the optimum read position, the interval of the projections 82 is made wider than the projection interval at the optimum read position 83.

IPC: G11B17/32
Filed: 1990-04-20
Abstract: PURPOSE:To increase the negative-pressure sucking force and to improve the precision and reduce the cost by forming recessed parts around a head on the suction face of a stabilizing plate and cutting corner parts on the bottom side of these recessed parts to form undercut parts. CONSTITUTION:When a disk A is loaded to a turntable 7 and is rotated at a high speed by motor driving, the air pressure between double recessed parts 1c and 1c on a suction face 1a of a stabilizing plate 1 and the disk A is made negative by the change of an air current accompanied with this rotation, and the disk A is sucked to the side of the stabilizing plate 1 and comes into contact with a magnetic head 2 projecting from the stabilizing plate 1 with a certain contact pressure. Since undercut parts 1e are formed in both corner parts on the bottom side of recessed parts 1c and 1c of the stabilizing plate 1 and on the outermost peripheral edge side of the suction face 1a, the variance of the negative pressure generated between recessed parts 1c and the disk A is reduced and the negative pressure is increased.

Filed: 1980-07-30
Abstract: PURPOSE:To control the wind amount by forming the third passge on the viscous fluid coupling consisting of a bimetal and a valve plate and controlling the rotation of the cooling fan for cars in three stages. CONSTITUTION:When the air temperature exceeds the set value, 17b of a valve plate 25 opens, and the viscous fluid in an operating chamber 18 is supplied into an operating chamber 19. Accordingly, the rotaion of a rotor 13 causes power transmission between the labyrinth grooves 13a and 17a of a rotor 13 and a partitioning plate 17 respectively because of the viscosity of the viscous fluid in the operating chamber 19, and torque transmission arises to a cover 16. When the air temperature increases further and exceeds the second set temperature, 17c of the valve plate 25, also with 17b is opened. Therefore, the viscous fluid in a storing chamber 18 is supplied into an operating chamber 20 through 17c and 13d, and torque is transmitted to the cover 16 through the viscous fluid in the labyrinth grooves 13b and 15a between the rotor 13 and the casing 15 and torque increases.
