Title: Manufacture of superconducting coil
Inventor: SATO HIROSHI
IPC: B23K9/00
Filed: 1988-08-24
Abstract: PURPOSE:To form a superconducting coil having a welded part which has excellent cryogenic characteristics of 0.2% durability and fracture toughness even after it is heat treated by conducting a multilayer welding with a welding material having specific component ratio of all austenite structure, and heat treating it. CONSTITUTION:A multilayer welding is conducted with a welding material containing by weight 0.03% or less of C, 0.5% or less of Si, 5-12% of Mn, 15-20% of Ni, 16-20% of Cr, 1-3% of Mo, 0.1-0.25% of N and the balance of Fe as main ingredients and having substantially all austenite structure, and a heat treatment is then conducted to generate superconductivity of a superconductor. The C is of an austenite structure forming element which performs a role of stabilizing the austenite structure and improving 0.2% durability at a cryogenic temperature, but precipitates carbide at the time of heat treating to generate Nb3Sn to lose its ductility and toughness, and the C is accordingly contained 0.03% or less. The Si is contained, to obtain fusion-bonding metal of completely austenite structure, desirably 0.1-0.5%. The Mn is effective to add 5% or more as an element for suppressing a crack at a high 7 temperature welding, but if it exceeds 12%, the Mn is compounded with the S to increase an inclusion thereby to lose its toughness at the cryogenic temperature, it is contained 5-12%. The Ni is contained, to enhance the fracture toughness at the cryogenic temperature, 15-20%.

Title: Recording and reproducing method
Inventor: ISHIDA KEIICHI
IPC: G11B20/12
Filed: 1987-08-21
Abstract: PURPOSE:To reduce the number of error words generated depending on the deviation of word synchronization by dividing a recording data into two partial blocks and recording the data while inserting a synchronizing pattern between the partial blocks. CONSTITUTION:A synchronizing pattern detector 201 detects a synchronizing pattern from a recovered bit string 204 and outputs a detection pulse 205. A serial/parallel converter 203 is reset by the pulse 205 and converts the delay bit string 206 into a word string 207 in the word synchronizing timing represented by the synchronizing pattern. In the bit string 206, the recording data before 1/2 block with respect to the synchronizing pattern is outputted by a delay memory 202 and the reset synchronizing timing acts effectively from the initial bit of the first half partial block. Thus, the word synchronization of all data in the block is taken according to the synchronizing pattern inserted to the center of the block.

Title: Printing wire of dot printer
Inventor: OKADA YOSHINOBU
IPC: B41J2/25
Filed: 1982-11-30
Abstract: PURPOSE:To eliminate the operational delay of a printing wire to enable high speed printing while increasing the printing energy of a printing part, by enlarging the cross-sectional coefficient of the curved part of the printing wire as compared with the straight part thereof. CONSTITUTION:When voltage is applied to an electromagnet apparatus 8 to attract an armature 7, a printing wire 6 is moved to the direction Y shown by an arrow. At this time, the impact point of the printing wire 6 is spaced apart from the lateral end part 6c of a curved part only over a straight distance portion Z and, therefore, bending moment is generated in the curved part 6b which is then apt to deform. However, because the cross-sectional area (Z1-Z1 cross- sectional area) of the material of the curved part 6b is formed into an oval shape while the cross-sectional coefficient of the curved part 6b is enlarged as compared with the straight part 6a of said wire, deformation is prevented and the force in the Y-direction is directly transmitted to the straight part 6a to impact a dot againt the leading end 6d thereof. As a result, there is no delay in printing operation while high speed printing is enabled and printing quality and the numbers of printing copy sheets can be enhanced.
