Title: Magnetic sensor
Inventor: TAKAYAMA MASARU
IPC: G01R33/02
Filed: 1979-09-19
Abstract: PURPOSE: To give a self-return function by performing a winding providing a magnetically hard phase on a portion of a magnetic metal sheet band consisted of noncrystal materials.  
     CONSTITUTION: A crystal phase is deposited from a portion of a magnetic metal sheet band 1 consisted of noncrystal material substantially of noncrystal magnetic alloy sheet band prepared by a high speed quenching method (single roll method, both roll method, belt method, centrifugal quenching method or the like) by heating it with an infra-red ray, laser or the like. A magnetically hard phase 2 magnetized in a given direction is prepared and a winding is provided thereon. Thus, not only in a lower magnetic field, but also in a higher magnetic field the B-H loop is shifted towards the H axis direction. When one electrode of a magnet is brought to near a sensor, an acute pulse accompanied by an inversion of magnetization in noncrystal portion occurs. On the other hand, when it is get away, the pulse occurs again and returns to the original state.

Abstract: PURPOSE: To obtain a film excellent in transparency without bringing about any problems on molding, by a method wherein the surface temperature of a thermoplastic resin is specified when extruding the resin from an annular die to produce a tubular material, and the tubular material is inflated by an internal pressure.  
     CONSTITUTION: When extruding a molten crystalline thermoplastic resin from an annular die to produce a tubular material, the resin is extruded with the surface temperature of the resin specified to be higher than that of a central part of the molten resin by 5W50°C, and the tubular material is inflated by an internal pressure to produce a tube. Then, the tube is cooled, is wound up and is subjected to an inflation molding to produce a thermoplastic film. A polyolefin based resin is preferably used as the crystalline thermoplastic resin. The temperature of the central part of the molten resin mentioned above means the temperature equal to the average temperature of the molten resin before extruded through the annular die in steady state. To specify the surface temperature of the resin at the time of extrusion to be higher than that of the central part by 5W50°C means that the resin is externally heated to said higher temperature at the time of extrusion by a heater which is provided at the outlet part of the annular die.

Filed: 1992-05-14
Abstract: PURPOSE:To improve a long service life and high stability of a sensor which gives the reference potential of a monitoring system in hot water or radiation area by fitting a plate with an optional surface roughness in a liquid junction part of the sensor. CONSTITUTION:A sapphire plate 3 is placed on a sensor body 4 made of sapphire. The contact faces form a liquid junction part from sensor internal liquid thru test solution. The surface roughness of both sapphires determine the diameter of clearance where the liquid flows in the liquid junction part, and when the clearance becomes smaller, an outward flowing of the sensor internal liquid will be suppressed, thereby prolonging a service life of the sensor. However, it must have a sufficient dimension so that the ion may flow. In addition, a tip sleeve 1 is attached on a sensor body 4 at the sensor tip section. The junction of the sleeve 1 and the body 4 adopts metalizing and silver soldering methods according to a Ti metal method.

Title: Equipment for preventing misinserting of package
Inventor: IGUCHI KATSUYA
IPC: H05K7/14
Filed: 1995-05-22
Abstract: PURPOSE: To surely prevent a plurality of packages from being misinserted to other places than specified slots in an equipment for preventing the misinsertion of a package in a shelf, etc. CONSTITUTION: At the time of inserting a package 3, an anti-misinsertion mechanism 13 is connected to a connector for preventing the misinsertion 33 before a main connector 12 of the package is connected to a main connector 32 of a back board. When the package is normally inserted, an electromagnet works and attracts a magnet of a movable piece 17 and thereby the movable piece gets into a non-projecting state. Therefore, the package can be inserted and the main connector of the package sets in and is connected with the main connector of the back board. When the package is misinserted, however, the movable piece is pulled by a spring and gets into a state of projecting from a face of the anti-misinsertion mechanism and agrees with an insertion stopper 36.  Therefore, the package cannot be inserted beyond a specified section and thereby the misconnection of the main connector of the package to the main connector of the back board can be prevented.
