摘要： PURPOSE:To make it possible to apply sufficient force to a wire to enhance its linearity and improve a work machining accuracy by using a copper and zinc plated carbon-fiber single yarn made of sintered pitch as a wire electrode material. CONSTITUTION:A carbon-fiber yarn 2 made of a fine sintered thread of pitch material derived from petroleum or coal is plated with copper 3 and zinc 4 to obtain a desired wire electrode material 1. Tensile strength of the wire electrode material 1 thus reaches 250 to 300kg/mm , and its tensile force is great enough to apply sufficient tension to the wire, and further tensile elastic modulus reaches to 30,000 to 60,000kg/mm . Linearity of the wire can thus be enhanced, and a work machining accuracy can be improved.

摘要： PURPOSE: To reduce the weight by provide a concave mirror consisting of a laminated structural body which is formed by using a fiber reinforced plastic material as a reinforcing material and has a reflection surface on a concave surface. CONSTITUTION: The concave mirror 3 is constituted by laminating a glass sheet 5 on the concave surface of the sheet 4 of the carbon fiber reinforced plastic material formed to a spherical shape and depositing aluminum and silicon oxide protective coating by evaporation on the surface of the glass sheet 5 to form the reflection surface. This concave mirror 3 is used by installing the mirror on the front surface of an image generating means in combination with a beam splitter. While the concave mirror 3 having the laminated structure is provided with high rigidity in such a manner, the thickness thereof is reduced to reduce its weight. As a result, the weight of the image display device is reduced.

摘要： PURPOSE:To obtain a diaphragm of a large specific elastic modulus having suitable internal loss, whose high-frequency characteristic of compass is excellent, by using a cloth of a specific aromatic polyamide fiber for the base of the surface material of a speaker diaphragm having three-layer sandwich constitution. CONSTITUTION:The surface material made of thin film of fiber reinforced plastic is adhered on both surfaces of a core member made of core material and thus the speaker diaphragm of three-layer sandwich constitution is produced, and for the base of the surface material, a cloth of an aromatic polyamide fiber plated with nickel is used. The preferable thickness of said plating is 0.05-0.5mum. Said plating is executed on single piece of the aromatic polyamide fiber of on the roving of the state of keeping the clearance of single fiber, and the plating layer should preferably be formed uniform on the whole surface of the single fiber. Thus the diaphragm has the large specific elastic modulus, hence it propagates the vibration of a voice coil bobbin faithfully when it is used being connected with the voice coil, also, since it has a suitable internal loss, a reflecting vibration from the edge is absorbed, hence the deviation in the high-frequency characteristic of compass is minimized.

摘要： PURPOSE:To obtain a single yarn of carbon fiber which enables a machine to decrease its wearing in an electrified part and a guide part, by forming a pitch material, produced from petroleum or coal, into a fine wire to perform its firing so that the wire increases its strength with no winding habit to a reel. CONSTITUTION:A wire electrode material 1 is formed by a single yarn of carbon fiber in which a pitch material is formed into a fine wire to perform its firing. And the machining method by the wire electrode material 1 is such that it is mounted to a wire cut electric discharge machine being held by an upper part guide 2 and a bottom part guide 3 and cutting a workpiece 4. This electrode material 1, having high wire strength, can be given sufficient tension even if it is formed into a very fine wire, and the machining accuracy improves by enabling a drum phenomenon of the workpiece 4 to be prevented. While the material, providing good linearity of the wire with no winding habit to a reel, improves the smoothness of a cut surface. And the material further decreases wearing in the upper and bottom part guides 2, 3 and an electrified part.

摘要： PURPOSE:To prevent the generation of the cracking in an exposed mask when the mask is automatically washed in unattended operation, by confirming the complete setting of the exposed mask on a stage with set confirming sensors. CONSTITUTION:An exposed mask 2 is clamped with a robot hand and set on the stage of a washing machine. Then, detecting pins 9a of four divided stage tables 1A, 1C and the like of the stage are protruded by a specified amount. Said protrusions are detected by metallic approach sensors 9b of confirming sensors 9, which are provided at corresponding positions. Thus the complete setting of the mask 2 is confirmed. The washing of the mask 2 is automatically started. In this way, yield of cracking of the exposed mask due to incomplete setting at the time of unattended automatic washing operation is prevented.

摘要： PURPOSE:To facilitate adjustment of a laser-light taking-out angle when a window is replaced, to eliminate change in laser mode and change in output and to obtain a highly accurate laser oscillator, by providing an angle adjusting device at a laser-light taking-out window. CONSTITUTION:An angle adjusting device at a laser-light taking-out window has a bellows attaching tool 14 and a supporting plate 11, which supports the tip part of micrometers 13 that are attached to an optical base plate 12. A window 7 is provided at the bellows 14 through the optical base plate 12. The bellows 14 are formed so that the optical base plate 12 is freely operated. Laser light 9a is taken out of the window, which is a laser-light taking-out window at a desired angle. At this time one or both of the micrometers 13 are manipulated. Then the bellows 14 are contracted or expanded by the optical base plate 12, which holds the micrometers 13. Thus, the window 7, which is contacted with the optical base plate 12, is moved, and the taking-out angle of the laser light 9b can be obtained.

摘要： PURPOSE:To make it possible to easily release a sandwich structure and to improve the close adhesiveness of aluminum, by a method wherein the plating processing of a non-ferrous metal inferior to close adhesiveness is applied to the surface of a mold having received mirror surface finishing and comprising a material low in liner expansion coefficient and a fiber reinforced plastic (FRP) plate of a semi-cured state is placed on the plating layer to mold a reflective mirror base material under heating and pressure while a mirror surface is transferred to said base material and a non-ferrous metal is adhered thereto before a metal having high reflectivity is vapor-deposited to said non-ferrous metal layer. CONSTITUTION:A hard non-ferrous metal layer 11 inferior to close adhesiveness to a mold is plated to the upper surface of a mold frame 10 having received mirror surface processing. A FRP plate 3, a central member 2 and the FRP plate 3 are laminated to the surface of the plating layer in this order through film like adhesive layers 4 and, when the whole is molded under heating and pressure, a mirror surface is transferred to the FRP plate 3 contacted with the mold 10 through the non-ferrous metal layer 11 and the non-ferrous metal layer 11 is adhered to said surface apart from the mold 10. A metal 12 having high reflectivity such as aluminum is vapor-deposited to the FRP plate 3 constituting a sandwich structure 1 having received mirror surface finishing to prepare a reflective mirror wherein the mirror surface finishing of the FRP plate 3 after molding became unnecessary and a working time is shortened.
