Title: Connecting method of optical fiber
Inventor: HAIBARA TADASHI
IPC: G02B6/26
Filed: 1982-09-30
Abstract: PURPOSE:To connect polarized-wave conservative optical fibers together while their main axes are aligned to each other, and to propagate light while their planes of polarization are held, by pressing one of two main axes and a slanting end surface against each other and making the connection. CONSTITUTION:An elliptic core type polarized wave conservative optical fiber 1 has a core and an end surface 12. The end surface 12 has main axes 10 and 11 and is cut or polished slantingly to the main axis 10. When polarized wave conservative optical fibers 3 and 3' having slanting surfaces are connected together, the end surfaces are pressed against each other, and heated and welded by discharge arcs 5 and 5 of discharge electrodes 4 and 4'. Two axes of the fibers are aligned to each other by pressing the end surfaces against each other, so they are connectable at a connection point without disordering the planes of polarization. In addition, deterioration in S/N ratio is prevented by shifting two main axis positions at the connection point.

Title: Production of high manganese cast steel product
Inventor: MOCHIZUKI TSUTOMU
IPC: B22C9/02
Filed: 1980-12-02
Abstract: PURPOSE: To produce cast steel products of superior quality having no burning defects on the surface by using a mold molded of olivine sand in casting high manganese steel by a vacuum casting method.  
     CONSTITUTION: In casting products of superior abrasion resistance such as tooth parts of crushers and abrasion resistant, rails, high manganese cast steel which contains 5W20% Mn, has superior ductility and toughness, and permits the formation of the surface layers of high hardness is used as a material and is cast by a vacuum casting method. If SiO 2  is contained much in the composition of a mold, it reacts with the MnO of the casting surface and erodes the mold surface, thereby generating burning defects on the surface of the castings. Hence, the rate of generation of the above-mentioned burning defects is decreased considerably by the use of olivine sand of relatively small contents of SiO 2  as a mold material.

Title: Magnetic disk
Inventor: SAITO MAKOTO
IPC: G11B5/73
Filed: 1987-07-10
Abstract: PURPOSE:To increase the intensity of recording magnetic fields in a magnetic medium layer without changing the spacing between a magnetic head and magnetic disk or the magnetic head by using a superconductor to form a nonmagnetic substrate or a part of the nonmagnetic substrate. CONSTITUTION:The superconductor is used in place of an aluminum substrate 3 which is used for the conventional magnetic disks. Namely, magnetic fluxes 4 from the magnetic head at the time of recording are prohibited by the Meissner effect of the substrate from intruding to the substrate and are passed between the head and the magnetic medium layer 1 if the disk substrate is constituted of the superconductor 2. The intensity of the magnetic fields in the magnetic medium parts is thereby increased and the recording performance is enhanced without narrowing the spacing between the magnetic disk and the magnetic head or without improving the magnetic head. An excellent overwrite characteristic is thus obtd.

Abstract: PURPOSE:To improve accuracy at the time of returning to a starting point by transmitting a command pulse to a driving system deciding the rotational frequency of a motor through a gate to be closed by applying a starting point pulse obtained by dividing a feedback pulse initialized by a program. CONSTITUTION:A CPU 1 applies data X indicating an extent of movement to a pulse distributor 2 to carry out positioning. The distributor 2 supplies a command pulse CP to a deviation counter 3 through an AND gate 8 and an output of the counter 3 is converted by a D/A converter 4 to drive a motor 5. When a robot is moved close to the starting point, a mechanical limit switch is depressed, a starting point detecting signal LS is turned to ''H'' and the CPU 1 controls so as to reduce the moving speed, so that an FF 9 is initialized by the CPU 1 at the rise of the signal LS and set up by the original starting point pulse BP to close the gate 8. Consequently the pulse CP is stopped being supplied and the coasting distance of the robot can be fixed.
