IPC: G11B5/58
Filed: 1981-07-08
Abstract: PURPOSE:To ensure close contact of a magnetic head without using a roller by making the reading face of the magnetic head rotatable to enable the reading face to follow distortion or inclination of a card and limiting the angle of rotation by two positioning members. CONSTITUTION:Two positioning members 29 are cut up vertically from a guide member 10. The positioning members 29 are in contact with a part near holding frames of elastic members 30, 31 in an attached state of a movable body 18, and determine offset position of the reading face 16a of a magnetic head 16. Being pivoted at the ends 24, 25, the elastic members 30, 31 are slightly energized in the direction of the arrow 34 near the magnetic head. Accordingly, the elastic members 30, 31 bring the reading face of th magnetic head into very close contact with the magnetic card 14. The positioning members 29 provide stop position of rotation of the movable body 18. They have flat parts 29b parallel to the reference face of the guide member 10 to smooth rotation.

IPC: H01L39/04
Filed: 1988-05-02
Abstract: PURPOSE:To prevent the evaporation of the liquid nitrogen located in the vicinity of a superconducting coil due to radiant heat by a method wherein a radiant-ray shielding plate is provided on the outer circumference of a liquid nitrogen container, and the above-mentioned radiant shielding plate is thermally contacted to the liquid nitrogen container located in the vicinity of the surface of the liquid nitrogen. CONSTITUTION:A radiant shielding plate 9, consisting of the material having a high coefficient of thermal conductivity such as copperm aluminum and the like, is attached to the liquid nitrogen container 3 using the thermally contacting method by conducting a welding work, a silver-soldering work and the like. As the radiant shielding plate 9 becomes a liquid nitrogen temperature by the conduction of heat, there is temperature difference between the radiant shielding plate 9 and the liquid nitrogen container 3, and there is no heat infiltration by radiation. Also, the liquid nitrogen in the vicinity of the surface of the liquid nitrogen is evaporated by the heat infiltrated into radiant shielding plate 9 from a vacuum container 5 through the intermediary of the radiant shielding plate 9. As a result, no bubbles are generated in the liquid nitrogen located in the vicinity of a superconducting coil, and the lowering of the cooling efficiency of the superconducting coil can be prevented.

Title: Apparatus for detecting defect on insulating layer surface of electric cable
Inventor: RICHIYAADO TOOMASU RAGUROTSUTA
IPC: G01N19/08
Filed: 1990-04-25
Abstract: PURPOSE: To make it possible to detect a fine surface damage on a sheath generated during manufacture by detecting the pressure change or flow increase generated when a surface defect passes below the outlet of a pneumatic detecting probe. CONSTITUTION: A spring push probe 22 having an axial direction air passage is arranged near a cable surface. A cable 10 is linearly moved under the probe 22. When the air is introduced from a pressure regulated air source 28, an air stream is generated at the surface near the outlet orifice and along the surface of the probe 22. The probe 22 is floated at a predetermined interval from above the moving surface, and floated by the air pressure. In the case of smooth surface, the static pressure at the outlet orifice is approximately constant. However, in the case of the surface defect like scratch damage or protrusion, the air stream is considerably changed, and a marker 36 disposed on an air probe head 21 responds to the sign of the pressure change such as pressure drop.  This change is detected by an air flow detector 34, digitally displayed on a display 35, and recognized as the sign of the defect.

Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To improve adherence of a lead frame and mold resin and obtain stable optical transmission characteristics, by forming a recessed part in an island on which a light emitting semiconductor element is fixed. SOLUTION: A lead frame 10 of the light emitting side has an island 102 on which a light emitting element is mounted and lead parts 103, 104 which are connected with the outside. In the island 102 on which the light emitting element is mounted, a recessed part 110 whose width X is almost 0.3 mm is formed in the vicinity of the center of the end portion, and corners 111 exist at both ends of the recessed part 110. In the case that a photocoupler is formed, since the recessed part 110 is formed on the island 102, light transmitting resin flows from the recessed part 110 to the lower surface side of the lead frame, so that the light transmitting resin does not stick on the upper surface of the lead frame, when the position of a dispensor with which the light transmitting resin is filled is slightly deviated. Hence adherence of the lead frame 10 and mold resin is improved.

Abstract: PURPOSE:To improve electrolyte leakage resistance by forming a hydrophobic layer of a copper-imidazol complex which is formed by previously being coated with alkyl imidazol in the periphery of the part, to which a sealing gasket is fitted, of a current collector made of the drawing material of copper based metal. CONSTITUTION:A current collector 16 is made of the drawing material of copper based metal such as brass and nickel silver. A hydrophobic layer 24 of a copper- imidazol complex which is formed by previously being coated with alkyl imidazol is formed in the periphery of the part, to which a sealing gasket 16 is fitted, of the current collector 16. The alkyl imidazol attached on the current collector 16 gradually reacts with copper which is a constituent of the current collector 16 and forms the hydrophobic layer 24 made of a copper-imidazol complex which is hydrophobic on the surface of the current collector 16. By the existence of the hydrophobic layer, the creepage of an electrolyte caused by wetting phenomenon is retarded and electrolyte leakage resistant performance can be increased.
