Title: Magnetic head field inverting drive circuit
Inventor: TANAKA TERUYOSHI
IPC: G11B5/09
Filed: 1995-01-04
Abstract: PURPOSE: To rapidly invert a magnetic head field by preventing currents to be generated at the time of changing currents owing to a flyback voltage and an induced voltage by a diode or a transistor or an FET. CONSTITUTION: The moment the transistor 1 becomes the nonconductive state (off), the head 6 as an inductor has the nature of keeping flowing of a current 11 (inertia), so that a positive flyback voltage higher enough than a power source voltage 29 is generated at a junction 26. When the flyback voltage is generated, a free oscillation (resonance) is generated by stray capacity of coils 6 and 7 and joint capacity of the diodes 8 and 9, etc., the flyback voltage becomes 0 volt after forming a peak voltage. The current 11 flowing in the coil 6 becomes 0, and a current 12 flows in the coil 1 which is reversely wound, so that the magnetic head field is rapidly inverted.

Title: Radiation source estimating method, radiation exposure estimating method and optimal measuring device to practice these methods
Inventor: NOMURA NORIO
IPC: G01T1/167
Filed: 1995-02-17
Abstract: PURPOSE: To determine a radiation source position on the basis of an intersection of crossing circles of mutual spherical surfaces by measuring a dosage equivalent rate of a radioactive ray at three or more measuring points, and finding a spherical surface locus of a point at which a radiation source can exist from plural measuring points and the ration of respective dosage equivalent rates. CONSTITUTION: For example, three points P1 , P2 and P3 are selected as measuring points, and dosages R1 to R3 of radioactive rays at points P1 to P3 are respectively measured. When P2 is put on the coordinate origin (0, 0) and P1 is put on (-a, 0) and a radiation source T is put on (x, y), [R1 =k/ (x+a)<2> +y<2> }, R2 =k/(x<2> +y<2> )] is realized, and T(x, y) draws a locus of a circle. When this is expanded to a three- diemsional space, a locus of the radiation source T becomes a sphere S12 . Similarly, spheres found from (P1 and P3 ) and (P2 and P3 ) are respectively denoted by S13 and S23 , these crossing circles becomes three. The crossing circles ought to cross each other at one point, and this intersection can be estimated as a position of the radiation source T.  According to this method, the position of the radiation source T can be estimated by measurement at least at three measuring points.

Abstract: PURPOSE: To prolong the service of cylinder and to lower the noises produced by air blast at the time of actuating brake, by effecting opening and closing of the exhaust-brake valve swiftly and preventing intrusion of dust and rain water into the cylinder.  
     CONSTITUTION: As the piston is urged toward the body of exhaust brake by the compressed air supplied from control valve member 9, air in the air cylinder is passed through inlet-outlet passage 2 and branched outlet port 2' into pipe P 2  and then carried into exhaust pipe 17 from small-diameter outlet port 14. Resultantly, by the multiplied function of negative pressure in pipe P 2  and venturi effect depending on the position of outlet port 14, the speed of air discharged from the bottom of air cylinder is increased so that plate-like valve element 8 can be closed swiftly. Further, there is no fear of outlet port 14 being blocked by injection pressure since it is not exposed to the outside, and noises caused by air injection can be lowered considerably since air is injected into exhaust gas in exhaust pipe 17.
