Title: Production of information recording medium
Inventor: MATSUZAWA HIDEKI
IPC: G11B7/26
Filed: 1988-06-03
Abstract: PURPOSE:To prevent camber and distortion from generating in a disk substrate by welding ring-type spacers to the under surface of a resin substrate, stacking this substrate on another one and welding said spacers to the another substrate. CONSTITUTION:The ring-type outer and inner spacers 22 and 23 are placed on a supporting table 26, on which the disk-type resin substrate 21 is stacked with its recording layer down. Then ultrasonic horn 25 is brought to contact to weld and joint the substrate 21 and spacers 22 and 23. Another disk-type resin substrate 31 is placed on the supporting table 36 with the recording layer up, on which the former substrate 21 with spacers is stacked with the spacers down. The substrate 31 and spacers 22 and 23 are jointed with using the ultrasonic horn 35. By this method, the obtained disk has little distortion and excellent dimensional accuracy, so that the surface vibration and axial accelation of the medium during driving can be reduced.

Title: Ferromagnetic metal powder
Inventor: ASADA SEIICHI
IPC: B22F1/02
Filed: 1982-08-09
Abstract: PURPOSE:To form surface phase of corrosion resistance metal in the thickness of 2.5-30Angstrom  and thereby manufacture excellent corrosion resistance metal powder by placing the metal powder mainly consisting of iron in contact with metal carbonyle in the gas phase or liquid phase and thereby decomposing the metal carbonyle at the surface metal powder. CONSTITUTION:Metal powder is placed in contact with at least one metal carbonyle selected from the carbonyle compounds of cobalt, nickel, chromium, tungsten, molybednum, vanadium, ruthenium, osmium, iridium and rhodium, and it is thermally decomposed. A thermal decomposition temperature is different in respective metal carbonyle. For example, the spicular iron magnetic powder is suspended in toluene, and CO2(CO)8 is dissolved into this suspension. Thereafter it is held under a temperature of 100-110 deg.C for five hours and the CO2 (CO)8 has been thermally decomposed. After such heat treatment, the suspension is cooled to a room temperature. Here, the metal powder is filtered and dried up under the vacuum condition. The surface metal phase in the thickness of 2.5Angstrom  or less has poor corrosion resistance and that in the thickness of 30Angstrom  or more shows adverse effect on the magnetic characteristic and results in increase of cost.

Title: Device for connecting optical fibers by welding
Inventor: SATO MAKOTO
IPC: G02B6/255
Filed: 1985-06-24
Abstract: PURPOSE:To automatically set an end face position by providing a contact sensor to a stopper for setting the end face position and controlling the feed mechanism for the front ends of optical fibers by the output from the contact sensor. CONSTITUTION:A grasping body 41 retreats and contacts with a limit switch 48 when a right side motor 46 runs backward under the control of a microcomputer 90. A control signal is then inputted via a NAND gate 80 to the microcomputer 90. The motor 46 is stopped by the command thereof. A left side motor 46' similarly stops when the grasping body contacts with a limit switch 48'. Then a motor 25 for lifting a stopper plate operates and the contact sensor 21 moves to the prescribed up position of a gripping part 10. A pair of the terminated optical fibers 1 are grasped in this state by the right and left grasping bodies 41 and are set in the V-groove 11 of the gripping part 10. The end faces of optical fibers are finally heated by a discharge electrode 31 and are welded while the optical fibers are axially fed. The fiber is released from the body 41 upon ending of the welding by heating and is removed. The end face position of the optical fibers is thereby automatically set.

As a result, oxide layer 2 is formed on the surface of Al1 and fine holes 3 are made. Thickness (t) increase as the anode processing time becomes longer. Next, acid is removed and after neutralization and rinsing, it is dipped in an aqueous disperse solution of a fluorohydrocarbon polymer such as tetrafluoropolyethylene and treated for approximate 20W30 minutes at a bath temperature of 70W90°C to fill fine holes 3 with polymer 4. The pipe diameter should previously be smaller as much as increment (a). In this way, strong products can be obtained which are harder than stainless steel.
