Abstract: PURPOSE:To enable a wire to be easily connected without using an auxiliary means by straightening a wire electrode thereafter conducting an electric current in one part of the wire electrode, melting it to be cut in the bottom of an upper part wire guide while applying tension and inserting the wire electrode to a bottom part wire guide via a workpiece in its through hole. CONSTITUTION:A wire electrode 1, applying tension of elastic limit or more, is straightened, thereafter removing the tension, the wire electrode is cut melting in the bottom of an upper part wire guide block 37 while applying tension with an electric current conducted in one part of the electrode, and the cut melting wire electrode 1 is inserted to a bottom part wire guide block 11 via a through hole in a workpiece 9. Accordingly, the wire electrode 1, prior to its cutting, generates a plastic deformation decreasing the diameter while straight extending, and a winding habit of the wire electrode, when it is wound on a bobbin, is removed. While the wire electrode 1, even after it is cut melting, holds the straightness, so that the wire electrode can be easily inserted to the bottom part wire guide block 11 via the through hole of the workpiece 9 positioned just under the wire electrode.

Title: Annealing device of resin base plate
Inventor: URYU YOSHIFUMI
IPC: B29C45/72
Filed: 1984-09-28
Abstract: PURPOSE:To contrive to improve the flatness of a resin base plate based upon the flatness of a heater by a method wherein the resin base is attracted to the heater by suction. CONSTITUTION:The air in a space 10 is exhausted through a suction hole 6. As a result, the space 10 in evacuated and the air in the top surface 2A side of a heater 2 is also exhausted through gaps 13, 11 and 12. Consequently, a resin base 1 is attracted to the top surface 2A of the heater 2. After that, the temperature of the heater 2 is raised by circulating heat transfer medium through cores 3 in the heater 2 in order to heat the resin base 1 with the heater 2. Because the top surface 2A of the heater is the surface with highly accurate flatness, the resin base 1 is straightened to the nearly same highly accurate flatness as that of the top surface 2A, resulting in preventing the deflection and warpage of the surface of the resin base plate from developing.

Abstract: PROBLEM TO BE SOLVED: To reduce influence of an optical nonlinear error to enable highly accurate measurement by including a light path from a laser light source to an interferometer block, a sealing tube for sealing separated light paths of reference light and measurement light, and a sealable container. SOLUTION: An entire light path from a laser light source 4 to an interferometer block 5A or 5B is covered by a sealing tube 20 to stabilize an atmospheric pressure inside. In addition, reference light passes through the inside of fixed sealable containers 7A, 8A, while measurement light passes through the inside of the fixed sealable container 7A and a triangular sealable container 9A. The sealing tube 20 is formed of a highly rigid metallic material, and a material with a small change in a light path length due to a change in temperature is chosen as a window material of the sealable containers 7A, 8A, 9A.  Thus an atmospheric pressure inside the sealing tube 20 and the sealable containers 7A, 8A, 9A is stabilized, so that the measuring apparatus for interferometer is free from deformation due to a fluctuation in atmospheric pressure or a fluctuation in temperature at the time of temperature control, while a fluctuation in a light path length of each light path part is small, and occurrence of measurement errors caused by a change in refractive index can be reduced.

Title: Apparatus for cooling liquid
Inventor: URABE NOBORU
IPC: F25D1/00
Filed: 1989-08-07
Abstract: PURPOSE:To make it possible to evaluate the operational efficiency of an apparatus for cooling liquid by providing a main control D which, by determining the amount of the liquid flowing through each of cooling devices and on the basis of the result obtained thereby, outputs signals of commands in specified modes. CONSTITUTION:A flow-control device 21 is to execute a first control to reduce the amount Qa of the liquid 2 flowing through cooling towers 9 to naught or a second control to follow up the amount Qa1 of the flow through a tower 9 on the right side. The main control 22 determines the amount Qa or Qa1 of the flow in each of the towers 9 and, every time the total amount Q of these flows exceeds a multiple of a prescribed amount Q0 of the flows with an integer, makes the flow-control device 21 start the second control in succession and, every time the total falls short of a multiple of an integer, makes it start the first control; the execution in both modes is ordered by outputting command signals 22a. Since, accordingly, the cooling efficiency E of one becomes equal to that of any other among the plurality of cooling towars 9 in action, the cooling efficiency E of the individual cooling towers 9 can be determined immediately from the total amount Q of the flows as one factor. Accordingly, the operational efficiency of the liquid-cooling apparatus 23 can easily be determined.
