Title: Production of base material for optical fiber
Inventor: NISHIMOTO MASAYUKI
IPC: G02B6/024
Filed: 1982-09-10
Abstract: PURPOSE:To produce easily a base material for an optical fiber for retaining the plane of polarization simply by the deposition of fine particles of glass by moving a burner around a quartz tube in synchronization with the rotation of said tube and moving the burner back and forth along the longitudinal direction thereof. CONSTITUTION:A quartz tube 10 consisting of SiO2 is held approximately horizontally, and is rotated circumferentially at a specified speed. A burner 11 is moved back and forth around the tube 10 to heat the tube. The burner 11 is moved back and forth within a 90 deg. rotating angle along the circumference of the tube 10 with the 1/2 rotation of the tube 10 as one cycle. At the same time, the burner 11 is moved back and forth at a specified speed along the longitudinal direction of the tube 10 as well. O2 and SiCl4, etc. are introduced into the tube 10 and fine particles of glass consisting essentially of SiO2 are formed by chemimical reaction and are deposited on the inside circumferential wall of the tube 10. The fine particles of glass are deposited over the entire length of the tube 10 then the rotation of the tube 10 is stopped, the burner is rotated 90 deg. circumferentially and the same procedure is repeated.

Title: Adhesive composition
Inventor: KOBAYASHI NOBUHIRO
IPC: C08F2/38
Filed: 1995-06-23
Abstract: PURPOSE: To obtain a high solid solvent type adhesive and a hot melt adhesive having superior physical properties such as heat resistance by using a polymer having polymer portions with 2 different glass transition points radiating out from a polyvalent mercaptan portion. CONSTITUTION: This adhesive contains a thermoplastic addition polymer having a polymer portion with a glass transition point of not lower than 273K and a polymer portion with a glass transition point of less than 273K, both extending from a polyvalent mercaptan portion in a radial manner. To obtain this addition polymer, a polyvalent mercaptan and a α,β- unsaturated monomer which turns into a higher glass transition point polymer are subjected to radical polymerization and then an unsaturated monomer which turns into a lower glass transition point polymer is added to this reaction mixture and radical polymerization is conducted. A 4-6 functional mercaptan which gives a star-shaped block structure is preferred as a polyvalent mercaptan.  A solvent type adhesive having a nonvolatile matter content of 60-80wt.% is obtained by soaking this addition polymer with an organic solvent. An acrylic hot melt adhesive is obtained by using an acrylic polymer in place of the polymer portions.

In order to separate into chips by the use of the device, firstly, scribing lines are produced with a diamond needle along the direction of cleavage of the GaAs substrate 3, which has a diameter of three inches and on which semiconductor elements are produced. After that, masking tapes 5 are applied to both the sides of the substrate. The peripheries of the resultant tapes are fixed to the ring 2. Finally, the ellipsoidal surface stage 1 is pushed against the substrate from below in order to separate it into chips 4.

Title: Production of plastic bonded gas diffusion electrode having manganese catalyst based on mn2o3 xmn5o8
Inventor: HANSU ZAUAA
IPC: H01M4/88
Filed: 1988-06-28
Abstract: In an electrically heated vibratory screw conveyor, manganese carbonate (MnCO3. x H2O) is thermally decomposed at about 500 DEG C to give the abovementioned manganese oxide catalyst which is then processed by dry, intensive mixing with a carbon-containing conductivity agent (carbon black, graphite, activated carbon) and PTFE as binder to give a highly active electrode mass which can be rolled into a carrier net of Ni or Ag. A two-stage mixing process is particularly advantageous in which the catalyst powder is initially premixed with only a little conductivity agent and binder, compacted and granulated. In a second mixing step, the granules are combined with the larger remainder of the intended quantity of conductivity agent and binder. The finished gas diffusion electrode has a biporous structure of hydrophilic and hydrophobic pore channels, which structure is highly advantageous for transport processes and the electrochemical conversion. The electrode can be used in fuel cells, chloro-alkali electrolysis cells and atmospheric oxygen cells.

IPC: C08J7/00
Filed: 1977-12-27
Abstract: PURPOSE:The title device designed to control the machining gap according to rough machining, finishing conditions, etc., by comparing the voltage applied to the gap between the electrode and workpiece with the reference voltage to convert and control the servo signal generated depending on the difference between the voltages at a value suitable by the machining state. CONSTITUTION:The voltage of pulse discharge effected between the electrode 1 and workpiece 2 is detected by the resistance circuit 5 and compared by the discriminator circuit 6 with the reference voltage. The discriminating pulse is output only during the normal discharge (V1 - V2), and converted to the micro pulse width by the conversion circuit 7, then counted by the counter 8. The output of the divider 9 is converted to a proportional voltage by the conversion circuit 11, and applied as a reference voltage to the control circuit 12. The detected voltage is compared with the reference value, and the voltage difference is output as a servo signal. The machining gap is narrowed to increase the machining speed during the steady machining; and the reverse during the unsteady machining, thus effecting the adaptive control.

Title: Curved surface transfer method
Inventor: MIYAKOSHI MITSUTOYO
IPC: B29C59/04
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To efficiently manufacture a decorative material having a three- dimensionally uneven surface. SOLUTION: The curved surface transfer method is performed as follows: a transfer layer side of a transfer sheet S consisting of a supporting body Sa and a transfer layer Sb is disposed in opposition to an uneven surface side of a base material B for effecting a transfer on its uneven surface; solid particles P are caused to collide against the supporting body side of the transfer sheet, so that the sheet S is pressed against the material B under the collision pressure; after the layer Sb is adhered to the material B, the body Sa of the sheet S is peeled off so that the layer Sb is transferred to the uneven surface of the material B; as the transfer sheet S, a sheet forming fine irregularities at least in an area to be brought into contact with the uneven surface of the base material is used.  Since the air A between the sheet S and the base material B escapes through the fine irregularities of the sheet S, the sheet S comes into close contact with the uneven surface of the material B so that transfer can be effected without fail.
