Patent JP-S62270079-A (JP)
Title: Case inspection method for floppy disk
Inventor: MATSUSHITA TOSHIHIRO
IPC: G11B23/033
Filed: 1986-05-19
Abstract: PURPOSE:To easily detect the protrusion from a liner by detecting only a scattered light from the liner on a straight line inclined by a prescribed angle with respect to the direction of propagation of an irradiating beam at the edge part of a case to be inspected. CONSTITUTION:A beam 2 from a projector 1 is set so as to be projected to the edge part of a case 8. When a liner 3 is not protruded from the edge part of the case 8, a part of the beam 2 is interrupted by the case 8 and others go straight on as they are. Consequently, the beam 2 is not made incident on a photodetecter 4, and the light receiving quantity of the photodetecter 4 is small. On the other hand, when the liner 3 is protruded from the end part of the case 8, a part of the beam 2 is interrupted by the case 8, others are scattered by the liner 3, a part of the scattered light is made incident on the photodetecter 4 and the light receiving quantity of the photodetecter 4 comes to be larger. Thus, the size of the light receiving quantity of the photodetecter 4 is the size of the output voltage outputted from the photodetecter 4 to a deciding device 5, and based upon the size of the output voltage, the device 5 decides the presence and absence of the protrusion of the liner 3.

Filed: 1980-08-18
Abstract: PURPOSE:To prevent a glaze from flowing into snap lines by a method wherein the part of the glaze crossing the snap lines is narrowed in width when printing the glaze over the area crossing the snap lines. CONSTITUTION:When printing the glaze G over the area crossing the snap lines 2, recesses 8A, 8B crossing the snap lines 2 are provided so that the amount of the glaze flowing into the snap lines 2 will be small if such flowing-in of the glaze occurs.

IPC: G01R31/12
Filed: 1986-05-21
Abstract: PURPOSE:To forecast the generation of a creeping flashover, by arranging a simple antenna for receiving noise radio waves and an electric field intensity measuring apparatus which detects and measures the intensity of an electric field of the received noise radio waves to detect the generation of an external partial discharge with the measurement of the noise radio waves accompanying the generation of an external partial discharge. CONSTITUTION:A voltage from a high voltage power source 1 is imposed on a stator coil winding 2 to create a creeping flashover via a coil support plate 3 between the winding 2 and a coil support bracket 4. A noise radio wave generated by an external partial discharge can be received with an electric field intensity measuring device 6 via a handy antenna 5 utilizing a copper wire. The maximum of the electric field intensity thus obtained increases gradually with a rise in the applied voltage to cause a creeping flashover after being accompanied by maximum electric field intensity with a greater pulsing property. With such an arrangement, when the antenna and the electric field intensity measuring apparatus are used jointly at a withstand voltage test, the creeping flashover can be forecast. A processing corresponding to the results of measurement enables smooth execution of a test.

Filed: 1989-05-10
Abstract: PURPOSE: To make a device smaller and handier to carry about by constituting a hoisting and lowering mechanism which slides a wall part between a working position and an opening position to enable to manually push down an actuator. CONSTITUTION: An aerosol container assembly 3 is held at a fixed position with a nozzle block 10 and aerosol container assembly holding structures 23, and 29. An actuator 7 is held at the closing position by hanging a hook 45 of a latch 15 on a flange 16. A gate 8 is closed by engaging a groove 26 and a protrusion 27, and held at the closing position. Thus the passage between a valve rod 5 and an opening 6 is blocked up. Moreover, if a gate 8 is at the closed position, a stopper 17 is fastened on a catch 18. Therefore, manual pushing down of the actuator 7 to the starting position is prevented. If the gate 8 is fixed at the opening position, a deflector 21 releases the stopper 17 from the catch 18, and it becomes possible to manually push down the actuator 7 and to discharge an aerosol compound.

Title: Magnetic detector for paper pile
Inventor: MATSUI KUNIHIKO
IPC: G01R33/12
Filed: 1981-07-24
Abstract: PURPOSE:To prevent thermal runaway of a magneto-resistance element, by providing a protection circuit preventing thermal runaway for the magneto-resistance element, in a magnetic detector. CONSTITUTION:When a temperature of magneto-resistance elements 41, 42 is increased and a resistance value is reduced, a potential V1 of a circuit 1 is increased and an integration circuit 2 integrates (V1-V2). Thus, the output of integrator V2 is decreased and a bias voltage V0 is finally decreased, the internal power consumption of the elements 41 and 42 is reduced, the temperature is decreased and the resistance value is increased. Thus, since the elements can keep the same resistance value at all times, even if a large voltage is applied, the danger of thermal runaway can be prevented.

Abstract: PURPOSE:To efficiently detect the conductive material in glass fibers by magnetizing the conductive material contained in the glass fibers and detecting the magnetic flux generated by the conductive material in a sensor section formed by using a superconducting quantum interference element. CONSTITUTION:The conductive material in glass twist yarn 2 wound on a bobbin 1 is magnetized by a superconducting coil 3.
