摘要： PURPOSE:To sense the contact pressure in solderless terminal connection with good performance and high sensitivity by furnishing the coupling member with a load sensing element to sense the load on the coupling member at the time of solderless connection of the terminal. CONSTITUTION:A coupling member 6, which is interposed between an applicator 4 and a driver device to drive it and is coupled directly with the applicator 4, is provided with a load sensing element to sense the load on the coupling member 6 at the time of solderless connection of terminals. That is, a pressure sensor 10 consists of two pressure sensors 11, 11', one of which 11 is installed at the front 6b of a column 6a while the other 11' at the back. The first named sensor 11 is composed of two load cells 12, 13 arranged perpendicular to each other, among which one 12 is applied in the axial direction of the column 6a while the other 13 perpendicular to the axial direction. This allows sensing of contact pressure at the time of solderless connection of the terminal with good performance and high sensitivity.

摘要： PURPOSE:To accurately measure the eccentricity of a coating by detecting the boundary part between primary patterns and other patterns of an interference fringes and determining the primary pattern when the band width of the interference fringes is measured. CONSTITUTION:When a long-sized body 32 which moves vertically in a Y-axial direction passes through a die 17 for coating, a coating layer is formed on its outer periphery, but when this long-sized body 33 reaches the irradiation area of light irradiating devices 22 and 23, the interference fringes of the long-sized body 33 are projected on photodetection screens 24 and 25 with the scattered light of irradiation light. Consequently, primary patterns PX1 and PZ1 of the interference fringes on the screens 24 and 25 are picked up by CCD cameras 26 and 27 and inputted to a CPU, which measure pattern lengths XX1 and XZ1, and Z11 and Z12 of the patterns PX1 and PZ1 and also computes X11/X12 and Z11 and Z12. Those computed values are used to detect the relative eccentricity between the long-sized body 33 and its coating layer. In this case, the widths of the patterns PX1 and PZ1 are scanned lengthwise by specific optical systems to decide end points KX and KZ of the patterns PX1 and PZ1 where the values reach 0 or a specific value.

摘要： PURPOSE:To improve positioning accuracy without deteriorating operationability by applying a photo-resist layer to the surface of a workpiece to be machined by a minute drill, then covering the surface with a mask, exposing the layer, developing it, forming a lead by means of electric discharge machining, and machining the exposed face of the workpiece. CONSTITUTION:The surface of a workpiece 12 is applied a photoresist layer 14 made of polyisoprene or the like. And it is covered tightly with a mask having a pattern of precise micro holes 16a, exposed, and then developed by using a developer made of xylene or the like. As a result, only the portions of the photo-resist layer 14 just under the micro holes melts exposing the portions of the surface of the workpiece 12. And when a voltage is applied between a discharge electrode 20 and the workpiece 12, an electric discharge occurs between the end of the electrode 20 and the exposed face of the workpiece 12 forming micro holes or wound shaped leads 12. The machining by putting a minute drill 10 on the lead can, therefore, improve positioning accuracy without deteriorating operationability.

摘要： PURPOSE:To make it possible to set an outer diameter of coated film of optical fiber in a wide range of great and small sizes, by adjusting position of die depending upon two scattered patterns in irradiation of coated optical fiber with light rays or upon the two scattered patterns and the measured value of the outer diameter of the coated optical fiber. CONSTITUTION:The light irradiation systems 19 and 20 and the screens 21 and 22 are arranged in such a way that they sandwich the coated optical fiber 13. Two sets of projecting means to project the scattered patterns on the screens 21 and 22 when the coated optical fiber 13 is irradiated with light rays from the light irradiation systems 19 and 20. At the rear part of the coating die 14, the projecting means are arranged at an interval in the direction of the transfer of the coated optical fiber in such a way that the light irradiation directions at the projecting means are different each other and the outer diameter measuring device 28 is set at the rear part of the coating die 14. The scattered patterns projected on the screens 21 and 22 by both the projecting means are photographed by the cameras 23 and 24 and the position of the die 14 is adjusted depending upon the two scattered patterns.

摘要： PURPOSE:To coat a homogeneous and stabilized resinous coated layer on the surface of an optical fiber at high speed by connecting a vessel contg. a liq. resin to a die part provided at the bottom part of the vessel through a thin- walled connecting part and vibrating the die part with an ultrasonic vibrator. CONSTITUTION:A die part 3 is provided at the bottom part of a resin container 2 and a liq. resin 1 is coated on an optical fiber 6 passing through the resin container 2 and the die part 3 while providing an ultrasonic wave to the liq. resin 1 in the resin container 2 from an ultrasonic vibrator 4. At this time, the resin container 2 and the die part 3 are connected through a thin-walled connecting part 7 and the ultrasonic vibrator 4 is connected to the die part 3. Consequently, the die part 3 can be ultrasonically vibrated without being affected by the resin container 2, ultrasonic vibration is effectively exerted on the liq. resin 1 in the die part 3 and the resin is stably coated even when the optical fiber 6 is moved at high speed.

摘要： PURPOSE:To easily control the outside diameter of a resin covering of an optical fiber over a wide range by controlling the outside diameter of said resin covering by the temp. of the optical fiber. CONSTITUTION:An optical fiber base material 4 is heated and drawn by a fiber drawing furnace 5 to form the optical fiber 1, following which this fiber is passed through a temp. controller 8 and is controlled to a desired temp. For example, a liquid thermosetting resin or UV curing resin is, thereafter, coated around the fiber 1 by a coater 6 in the same manner as in the conventional method and in succession, the fiber is introduced into a heating furnace or curing furnace 7 such as UV irradiation furnace, by which the optical fiber 3 is formed. The outside diameter of the resin coating is thereby easily controlled in a several 10mum range with several mum accuracy.

摘要： PURPOSE:To enable accurate measurement of the degree of eccentricity, by adjusting the irradiation position of parallel light to an object to be measured so as to maximize the brightness level of the interference fringe of an image of a long-sized object on the light receiving side. CONSTITUTION:Covering dies 17, light irradiators 22 and 23, light receiving screens 24 and 25, CCD cameras 26 and 27 and the like are arranged. When a long-sized object 32 passes through the dies 17, a cover layer is formed on the circumference thereof. As the long-sized object 23 reaches the irradiation areas of the irradiators 22 and 23, an interference fringe pattern of the long-sized object 32 is projected on the screens 24 and 25 by the scattered light of the irradiation light. The interference fringe pattern of the long-sized object 32 is taken with the cameras 26 and 27 and inputted into a microcomputer (MC) to measure and compute the pattern length in the respective interference fringe patterns. Then, when the eccentricity can be measured based on the results of the computation, a signal is issued from the MC to adjust the position of the dies 17 to eliminate the eccentricity by finely moving adjusting bases 14 and 15. Thus, the degree of the eccentricity can be determined accurately by maximizing the brightness of the interference fringe.
