Title: Making method of optical fiber circuit
Inventor: KASHIMA GIYUU
IPC: G02B6/293
Filed: 1979-04-09
Abstract: PURPOSE:To make possible the constitution of various circuits of easy manufacture by coating photosensitive resin at the end part of an optical fiber, radiating light or electron beam to this then peforming chemical treatment thereby forming the specified patterns. CONSTITUTION:A photosensitive resin film 11 is coated on the surface of an optical fiber 10. Thence, if light of the intensity distribution as shown by arrows 12 is radiated, the resin film 11 is sensitized according to the intensity of radiation and causes a chemical change in the portions shown by 13. Said portions are developed and removed and further dipped in an etching solution 14. Since the amount of etching becomes small in the places where there is much resin film and becomes conversely large in the places where there is less resin film, the surface oblique to the optical fiber axis is obtained. If the resin remained in the final is removed, the optical fiber 10 having the desired worked surface is obtained. The use of an electron beam in place of light is equally well. Not only the oblique face but also the end faces of various shapes may be worked.

Title: Semiconductor pressure sensor
Inventor: HIRANO HIROKAZU
IPC: H01L29/84
Filed: 1984-03-07
Abstract: PURPOSE:To make sensing at high pressure or high differential pressure feasible while sustaining the same sensitivity and input.output characteristics as the low pressure sensor by a method wherein the optimum requirements for the fillet part curvature radius and the thickness of a diaphragm part are claculated. CONSTITUTION:Upon investigation of the relation between the fillet part radius R of a diaphragm and the punctual pressure, the later increases in proportion to the radius R, but when R/h (h represents the thickness of a diaphragm) exceeds 2, the puncture pressure is saturated not to be increased any more i.e. the puncture pressure is maximized if R/h exceeds 2. Therefore, when a diaphragm part is formed by anisotropic etching process, if t=R+h (t represents the thickness of semiconductor chip 7), the chip 7 is provided with the maximum withstand pressure if t>3h. However, substantially t>2.5h suffices due to some anisotropy in etching process itself. Besides, even if in case t>R+h, if R/h>2, the chip 7 subject to the maximum puncture pressure may be formed without fail.

Title: Damping transmission device
Inventor: KANASHIKI SUSUMU
IPC: F16D3/66
Filed: 1987-02-25
Abstract: PURPOSE:To transmit the max. torque by setting the position for installing an elastic member onto a trailing flange body at the position opposed to an arm, outside from an outer peripheral circle at the top edge of the arm of a driving flange body and using a large elastic member, thus damping the torsional vibration. CONSTITUTION:When a load does not act onto a coil spring 10, the center of a receiving hole 5 exists at the point P1, and the center of a receiving hole 15 exists at the point Q3, and when driving starts, the spring 10 is compressed, and the center of the receiving hole 5 shifts to the point P2 during the transmission of an average torque, while during the transmission of the max. torque, the spring 10 shifts to the point P3. The free length of the spring 10 is represented by l1, and during the transmission of the max. torque, the spring 10 contracts to the length l2, and the length of the connection between the points P1 and Q1 represents the length of a rod 19. Therefore, even if the spring 10 is contracted, and the free length contracts from l1 to l2, the shift quantity delta in the direction Y-Y perpendicular to the straight line X-X becomes exceedingly small, and the radius R for determining the laying position of the spring 10 can be reduced, and a spring 10 having a long free length can be used. Therefore, the large torque can be transmitted, markedly damping the torsional vibration.

Title: Removing method for removal type earth anchor
Inventor: NAKANO SUMIO
IPC: E02D5/80
Filed: 1985-03-06
Abstract: PURPOSE:To reliably remove an anchor through introduction of a low stressing force, by a method wherein, after an anchor is inserted into an anchor hole to anchor it by means of a grout agent, shrinkage in the direction of cross section is exerted on a core to remove the core, and tensile materials are re moved. CONSTITUTION:A tensile material 2 is inserted into each guide groove 11 in the outer periphery of a shrink spacer 1 to bind the tensile materials by means of bands 3. An anchor is then inserted into an anchor hole, and mortar is pressed in the front of the hole by a mortar filling means to form an anchor part and exert a stressing force on the tensile materials 2. A material is shrunk by exerting a stressing force on the shrink spacer 1, a distance is produced between the tensile materials 2 and the spacer, and after the shrink spacer 1 is removed, a stress force is exerted on the tensile materials 2 for pull off. This, since the outer periphery of the tensile material of the anchor part is separated from mortar for anchoring, enables a pull off force, serving to peel the tensile material from the mortar for anchoring, to be sharply reduced to a low value.

Filed: 1985-03-05
Abstract: PURPOSE:To prevent the generation of over-voltage applied to a de-Q-ing circuit by using a voltage division voltage of an output voltage Ebb of a high voltage DC power supply as a reference voltage of a comparator and changing the operating point of the de-Q-ing circuit in following to the increase in the Ebb. CONSTITUTION:A charge voltage VPFN of a PFN 5 is divided into a voltage VPFN' by dividing at a voltage divider 8. The voltage divider 13 divides the output voltage Ebb of the high voltage DC power supply 1 and the voltage dividing voltage is converted into a stable DC voltage by a voltage stabilizing circuit 14. The output voltage is added with a fine adjustment voltage formed by a DC power supply 12 and a variable resistor 11 by an adder 15 and inputted to a comparator 10 as a reference voltage VREF. The comparator 10 compares the VREF with the VPFN' and when the charging voltage VPFN of the PFN 5 reaches a prescribed level, a trigger is generated, which is given to the de-Q-ing circuit 9. The operating point of the circuit 9 changes in following to the Ebb, and the charging voltage VPFN of the PFN is set to 80% of 2Ebb.
