Abstract: PURPOSE: To manufacture a forging of uniform thickness by punching the material to be worked while exerting force thereto from below in the direction opposite to its elongating direction.  
     CONSTITUTION: The material 15 to be worked 15 is mounted to a lower die 14, and a cylinder 4 for elevating the material retainer and a cylinder 5 for elevating the punching punch are simultaneously lowered, to press the top surface of the material 15 with the under surface of a material retainer 10. On the other hand, an opposite cylinder 19 is operated to apply a constant pressing force to the bottom surface of the material 15 by way of a supporting plate 20. Thence, the cylinder 5 is lowered further to pass a punching punch 13 into a punch guiding hole 11 and insert the same into the material 15 which is receiving required pressing force at its bottom face, whereby the punching work is done and this makes possible the punching down into the end part unlike in the conventional art. After the punching, the cylinder 4 and the cylinder 5 are retreated, and the cylinder 19 is operated as a knockout cylinder, whereby the material 15 is taken out.

Title: Wire electric discharge machine
Inventor: GAMO GOTARO
IPC: B23H7/10
Filed: 1986-01-27
Abstract: PURPOSE:To eliminate risk of damaging electrodes by nipping each wire elec trode with a current supply contactor and a pressure member, holding the elec trode and contactor so that they do not separate in the event of discontinuity of the wire electrode, and thereby preventing generation of electric discharge between the contactor and wire electrode. CONSTITUTION:In the event of discontinuity of a wire electrode P during electric discharge processing, the tension applied to the wire electrode P eliminates, and it tends to deflect, but does not separate from a current supply contactor 10 because the wire electrode P is pressed and nipped by the contactor 10 and a bearing 19. Accordingly even a delay of shutoff of current supply to said contactor 10 because of output from a discontinuity sensing means for wire electrode P does not cause electric discharge between the wire electrode P and the current supply contactor 10, and therefore no damage is given to them. This eliminates risk of hooking of the wire electrode at the guide when the wire electrode is to be threaded to a guide, to facilitate automatic wire connec tion, and also, no damage is given to the current supply contactor, so that a long time service is made possible.

Abstract: PROBLEM TO BE SOLVED: To suppress producing long half-life radioactive species by containing Ni of which Ni-58 isotope is removed, in the structural material. SOLUTION: A rotary shell 18 is rotated in high speed with a motor 21 and compound gas of natural Ni such as celcarbonyl as stuff gas is supplied from a stuff gas supply pipe 29 in the rotary shell 18. The stuff gas is separated in the rotary shell 18 by the difference of isotope mass number. The gas Ni-58 is depleted, is exhausted from a depleted gas exhaust pipe 31 and the gas Ni is enriched, is from an enriched gas exhaust pipe 30. By passing through a plurality of separation processes, an Ni compound of which Ni-58 content is reduced, is obtained. When a parent material is dipped in high temperature water, oxide film is produced. There are two methods for putting Ni-58 on the film. One is a prefilming method to expose in high temperature water containing Ni treated by the isotope separation during fabricating the structure.  Another is a method to contact similarly to high temperature gas to evaporate.

Abstract: PURPOSE:To lessen the capacity of an electrode and to improve the high-frequency characteristics of a semiconductor element by a method wherein the electrode, overhanging on parts of a resist film from a window provided on the resist film, is formed and after the resist film was removed, a metal layer is performed an etching using the electrode as a mask. CONSTITUTION:A metal layer 9 is formed on the surface of substrate 6 in a height of h1. A resist film 10 is formed on the layer 9 and a window is opened on the resist film 10. A bump electrode 8, overhanging on parts of the film 10 from the window opening part, is formed in a height of h2. Moreover, after the film 10 was removed, an etching is performed on the metal layer 9 using the electrode 8 as a mask and the radius (r) of the layer 9 is lessened than the maximum radius R of the electrode 8. As a result, the floating capacity of a part A between the electrode 8 and the substrate 6 is reduced to nil, because the the radius (r) of the layer 9 between the substrate 6 and the electrode 8 is smaller than the maximum radius R of the electrode 8.

Abstract: PURPOSE:To obtain a heat accumulating device capable of generating heat surely when the heat is to be generated by a method wherein a path opening and closing means, communicating the inside of a crystal holding chamber with the inside of a heat accumulating vessel or separating them switchably, is provided in the titled device. CONSTITUTION:The heat of a heater 5 is generated before using a pocket heater to heat accumulating medium 3 or hydrogenated sodium acetate of crystalline phase in heat accumulating vessels 4a, 4b to the melting point (58 deg.C) thereof or higher. The hydrogenated sodium acetate of crystalline phase is gelled gradually and then is gelled perfectly. After the heat accumulating medium in the heat accumulating vessels 4a, 4b is dissolved perfectly, a plug 5b is pulled out of a socket and the heating is stopped. The temperature of the heat accumulating medium 3 in the heat accumulating vessels 4a, 4b is reduced under heat accumulating process, however, super-cooled condition is maintained and heat accumulation is effected under gelled condition. Under heating process, necessitating room heating, the bottom 66b of the spool 66 of a valve 6 is pushed, then, a valve body 63 is pushed up and a space A is communicated with the space B, therefore, the heat accumulating medium under the condition of over-cooled gel in the space A is contacted with the crystal species in the space B whereby latent heat, the heat medium, is crystallized at a stroke and latent heat accompanied by the transition of phase is discharged to effect room heating.

Title: Objective lens for optical disk
Inventor: TAKAMURA SACHIKO
IPC: G02B13/18
Filed: 1989-01-23
Abstract: PURPOSE:To compensate performance such as various aberrations excellently over a wide effective visual field and to make the objective lens tolerant to an axis shift by using a single aspherical lens which has aspherical surfaces with positive refracting power on the light source side and optical disk side and satisfying specific conditions. CONSTITUTION:The objective lens is the single lens which has the positive refracting power and aspherical surfaces on the light source side and optical disk side and satisfies the conditions shown by inequalities I - IV. In the inequalities, (f) is the focal length, (d) the core thickness, (n) the refractive index, r1 the radius of paraxial curvature on the light source side, r2 the radius of paraxial curvature on the optical disk side, and K1 the conical constant of the aspherical surface on the light source side which is shown by an equation IV. Astigmatism is generated outside the range of the inequality I and an on-axial comatic aberration due to the axis shift is generated frequently outside the range of the inequality II. Further, the relation between the conical constant of the light source-side aspherical surface and the ratio of the radii of paraxial curvature of both flanks of the single lens is maintained as shown by the expression III to obtain more tolerance to the axis shift. Consequently, the performance such as various aberrations is corrected excellently over a wide effective visual field and the tolerance to the axis shift is obtained.

Title: Analogue switch and sample hold circuit using it
Inventor: SHIBATA ATSUSHI
IPC: H03K17/687
Filed: 1978-02-09
Abstract: PURPOSE: To suppress substrate bias effects and make an on resistance uniform to reduce distortion by applying the substrate bias voltage fixed for input signals to the semiconductor substrate of a FET in the analogue switch.  
     CONSTITUTION: Analogue input signal e i  is applied to the source electrode of P channel MOS transistor 2, and sample hold signal e o  is obtained in the drain electrode of it. In this state, substrate voltage V sub  of transistor 2 is given by higher one of signal e i  and e o0  voltages. Consequently, when transistor 2 is in an on-state, the substrate voltage for the source potential is always set to zero. As a result, the fluctuation of the on resistance dependent upon substrate bias effects is suppressed, and the threshold voltage of the gate electrode is set to a fixed level.
