Title: Optical fiber
Inventor: YAMAMOTO MAKOTO
IPC: G02B6/02
Filed: 1984-05-23
Abstract: PURPOSE:To manufacture an optical fiber causing a very small loss due to scattering at a low cost by forming a reflecting film on the inside of a hollow pipe. CONSTITUTION:The reflecting film 3 is formed on the inside of a hollow pipe 2 to manufacture an optical fiber 1. A desired inexpensive material such as synthetic resin can be used as the material of the hollow pipe 2, and the reflecting film 3 is formed by vapor-depositing of coating a metal such as silver or aluminum. Light propagates through the internal space and scattering is negligible, so the degree of freedom of usable materials is considerably increased and the cost of the resulting optical fiber can be reduced. Since the reflecting film 3 is formed on the inside of the hollow pipe 2, light does not leak out of the pipe 2.

IPC: H05K3/18
Filed: 1990-04-18
Abstract: PURPOSE:To improve insulating resistance value between conductor lines by covering the entire surface side of a resin molded form for a board in which a circuit pattern protrudes with a coating material made of resin having high etched properties, then filling new resin material between the patterns and burying back it. CONSTITUTION:After the entire surface of a resin molded form 1 for a board in which a circuit pattern 2 protrudes on the surface is coated with a coating material 6 having high etched properties, and then cured. Then, new resin material 5 having insulation is filled between the patterns 2, and a part therebetween is buried back. When it is etched, only the surface of the material 6 is largely etched to be roughed. Further, when it is electrolessly electrolytically plated, a plated film is formed as a base layer by copper or the like through the material 6 adhered with a plating catalyst 4 on the pattern 2. Then, when it is electrically plated, a conductor line 3 made of copper, nickel and gold is finally formed only on the surface of the pattern 2 covered with the base layer.

Title: Printing head for wire impact dot printer
Inventor: YAMAMOTO KAZUHIKO
IPC: B41J2/235
Filed: 1995-04-27
Abstract: PURPOSE: To provide a printing head for a wire impact type dot printer effectively transferring the heat of a core block to a carriage by a radiation member easy to produce. CONSTITUTION: The attaching reference surface 5 parallel to a printing surface and developed in positional accuracy in a horizontal direction and a height reference surface 6 developed in positional accuracy in a height direction are provided to a carriage 1 and the rear surface 26 of the protruding part being the reference surface in the height direction of a nose frame 19 is brought into close contact with the height reference surface 6 while the radiation member attaching surface 23 being the reference surface in the horizontal direction and the attaching reference surface of the carriage 1 are brought into close contact with the carriage attaching surface 17 of a radiation member 11.  Since the positioning in the height direction of the nose frame 19 is not performed by the radiation member 11, it is unnecessary to precisely process the radiation member 11 and production becomes easy. Since the clearance between a core block 8 and the inner peripheral surface of the radiation member 11 can be reduced, heat conductivity is enhanced and the heat to the carriage 1 is sufficiently let escape.

Title: Oscillation circuit
Inventor: NISHI TSUTOMU
IPC: H03K3/354
Filed: 1994-05-18
Abstract: PURPOSE:To reduce the range in dispersion of a frequency of an oscillated clock signal by selecting a gate width of NMOS transistors(TRs) being components of 1st and 2nd inverter circuits to be a specific multiple of a gate width of PMOS TRs being components of the 1st and 2nd inverter circuits. CONSTITUTION:The gate width of NMOS TRs 6, 7 being components of 1st and 2nd inverter circuits is selected twice the gate width of PMOS TRs 1, 2 being components of the 1st and 2nd inverter circuits. Thus, the dispersion in the frequency of an oscillated clock signal OUT is reduced. For example, when the gate width of the NMOS TR 6(7) is selected to be 30mum (90mum), that is, twice the gate width of the PMOS TRs 1, 2, the dispersion range of the frequency is suppressed small as 0.22MHz. The current remains 1.595mA and then the current consumption is prevented from being increased and the chip area increase is minimized.

Filed: 1980-07-31
Abstract: PURPOSE: To surely recognize the state of progress during etching by forming a resist film having a prescribed pattern on a multilayer thin film laid on a substrate and leaving an etching margin made of thin film to be etched at a part except the pattern.  
     CONSTITUTION: A thin film consisting of the 1st layer 5 and the 2nd layer 6 is laid on a substrate 4, and a resist 7 having a prescribed pattern is formed on the layers. At an etching margin 8 the 2nd layer is directly formed on the substrate 4. By carrying out etching in this state, the part of the layer 6 not covered with the resist 7 is etched to form a pattern. At the same time, the layer 6 of the margin 8 is etched. Accordingly, even if the layer 5 is similar to the layer 6 in color tone, the state of etching can be judged by the difference between the margin 8 and the substrate 4 in color tone.
