Title: Copper or copper alloy tube
Inventor: OZAKI RYOICHI
IPC: B21C37/083
Filed: 1991-10-08
Abstract: PURPOSE:To provide a copper or copper alloy tube which can be improved productivity and reduced in production cost. CONSTITUTION:A coating layer consisting of respective elements of Sn, Zn, Fe, Ni, and Co or the alloy thereof is formed on the welded butt joints of planar materials consisting of copper or copper alloy. The thickness of the coating layer is specified to 0.1 to 10mum. After the coating layer is formed, both ends of the planar material are butted against each other and a welded. Since, the electrical conductivity and thermal conductivity of the Sn, Zn, Fe, Ni and Co are smaller than those of the Cu, the electric energy at the time of welding is efficiently transduced to heat energy and the heat energy is hardly diffusible. The weldability is, therefore, enhanced and the welding speed is greatly improved.

Inventor: YAMAGISHI HIROAKI
IPC: G11B5/84
Filed: 1987-10-15
Abstract: PURPOSE:To effectively prevent the cutting powder of a nonmagnetic supporting body raw sheet, etc., from being generated and to prevent an electromagnetic conversion characteristic and traveling durability from being lowered by performing the smoothing of a coating layer by making the coating layer of a magnetic coating material bring into contact with a smoother under a state where the noncoating part of the magnetic coating material is not brought into contact with the smoother. CONSTITUTION:The horizontal cross-section of the smoother 1 in a length direction is formed in circular arc or linear shape, or the combined shape of them, and a corner is provided at the terminating part 6a of a contact plane. Therefore, it is possible to smooth the surface of the coating layer 4 by making the sector arc part 2 of the smoother 1 bring into contact with the coating layer 4 of the coating material applied on the nonmagnetic supporting body raw sheet 3. Also, by notching the terminating parts 6a and 6b in a direction upper than the contact part with the coating layer, it is possible to evade the contact of the nonmagnetic supporting body raw sheet 3 with the noncoating parts 5a and 5b. In such a way, it is possible to prevent the cutting power from being generated effectively.

Thereby, a potential of the complementary data line is made an operation point, complementary data from the memory cell 1 selected by the complementary data line in this state is outputted.  Thereby, the sense amplifier functions appropriately and correct data can be outputted to the data line.

Abstract: PURPOSE:To obtain images having high image quality and good color reproducibility by making combination use of fine alumina powder and nitrogen- contg. fine silica powder as a flowability imparting agent. CONSTITUTION:The fine alumina powder and the nitrogen-contg. fine silica powder are used in combination as the flowability imparting agent and further, magnetic particles are coated with an insulating resin. If the nitrogen-contg. silica and alumina stick to the surface of a coloring agent-contg. fine particles having negative electrostatic chargeability, the negative electrostatic chargeability of this part is neutralized and the negative electrostatic chargeability of the other part is maintained. Namely, the part where the electrostatic chargeability is strong (the part where the flowability imparting agent is absent or extremely little) and the part where the electrostatic chargeability is weak (the part stuck with the flowability imparting agent) are formed on the surface of the toner particles. The electrostatic charge as the toner is extremely stable and such attenuation of the electrostatic charge as in case of using a conducting agent is hardly generated. The images having the high image quality and good color reproducibility are thus obtd.

Abstract: PROBLEM TO BE SOLVED: To enable caulking with a stable pressing force against the size irregularity of parts, by setting a rib-like fixing caulking projecting part for an adhering plate which is discontinuous in the circumferential direction inside a recessed part accommodating the ring adhering plate chamfered at the inner circumferential part, thereby constituting a turntable. SOLUTION: A fixing caulking projecting part 3b for an adhering plate is divided in three in the circumferential direction. Accordingly, a volume increase and decrease of parts collapsed by caulking due to a thickness irregularity of the adhering plate 8 or a height irregularity of the projecting part 3b, and the need of a large pressing force for a caulking jig are avoided. If the pressing force is increased, a turntable 3 requiring high accuracy is adversely influenced by a warp, a bend, etc. The projecting part 3b is divided in three to have a discontinuous constitution, so that a remaining part among the parts broken by the caulking after filling a space of an inner circumferential chamfered part of the adhering plate 8 escapes to a rib discontinuous part 3d.  The adhering plate 8 is fixed and held stably irrespective of a size irregularity of parts, thereby, the highly accurate turntable is obtained.
