Title: Manufacture of spacer for carrying optical fiber with colored part for identification
Inventor: SHIBAGAKI TETSUO
IPC: G02B6/44
Filed: 1988-03-23
Abstract: PURPOSE:To eliminate peeling in use and to improve the hardness of coloring by putting a wire element for identification together at the tip part of a rotary die and coating it integrally at the time of the extrusion coating of a tensile strength wire. CONSTITUTION:The resin of the spacer 3 is obtained by converging a resin flow A in a cross head die 2 from a cylindrical shape to a conic shape and putting it together with a coloring resin flow B supplied from another extruder at a die lip part which has a projection corresponding to the shape of the spacer 3. Namely, while the die lip is rotated, the outer periphery of the tensile strength wire is coated and the take-up speed and the rotating speed of the die lip are selected properly to obtain the spacer 3 with specific spiral pitch. Consequently, the spacer 3 which has the wire element for identification free from uncoloring is obtained without coloring by ink printing, etc.

Filed: 1997-03-04
Abstract: PROBLEM TO BE SOLVED: To prevent a drive voltage in forward direction from increasing by rejecting the increase in resistance of a gallium nitride(GaN) compound semiconductor due to plasma etching. SOLUTION: An insulation layer 191 that is made of SiO2 , a first metal layer 192 that is made of titanium(Ti), and a second metal layer 193 that is made of nickel(Ni) are successively laminated on a contact layer 17 that is made of p-type GaN, thus forming an etching mask 19. Then, the mask 19 of a specific region is eliminated, and one portion of a contact layer 17, a clad layer 16, an emission layer 15, a clad layer 14, and an n<+> layer 13 that are not covered with the mask 19 is etched by a reactive ion etching using a gas containing nitrogen, thus exposing the n<+> layer 13.
