Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To discriminate the characteristic of a radiation, e.g. the kind of the radiation, on the basis of its signal sound in a radiation detector which generates the signal sound when the radiation is detected. SOLUTION: The light emission of a scintillator 12a for α-ray detection and that of a scintillator 12b for β-ray detection are transduced into electrical detection signals by a photomultiplier tube(PMT) 14. In a waveform discrimination circuit 16, a detection signal which is output from the photomultipler tube 14 is discriminated into an α-ray detection signal and a β-ray detection signal on the basis of the feature of its waveform. The α-ray detection signal is input to a sound circuit 26a, and the β-ray detection signal is input to a sound circuit 26b. The respective sound circuits 26a, 26b generate signals used to generate signal sounds whose timbre is different from each other. Loudspeakers 27a, 27b are driven by the signals which are output by the respective sound circuits 26a, 26b.  By this constitution, a signal sound is output at a timbre which is different according to a case in which α-rays are detected and to a case in which β-rays are detected.

Title: In-tank liquid quantity control method and liquid supply/ ejection quantity control method
Inventor: MORI HIDEKI
IPC: G01F23/00
Filed: 1990-05-07
Abstract: PURPOSE:To attain the remote control of the liquid quantity and the liquid supply/ ejection quantity of many tanks by deciding the liquid level height of each tank by measuring electrically the drawn-out length of a weight hanging wire needed for a weight to reach the liquid level from its reference position. CONSTITUTION:A wire 3 is drawn out based on the position where a weight 2 touches a limit switch and stops, and the drawn-out length of the wire 3 is measured by a control mechanism 14 by counting the pulses sent from a measuring instrument 13. When the weight 2 reaches the liquid level LH, the tension of the wire 3 is reduced by buoyancy. Then a balance moves down and an electrical contact unit 2 is turned on. Thus the pulses received from a motor 12 and the instrument 13 are stopped. The mechanism 14 converts the integration of pulses into the distance between a reference position and the level LH and displays it on an LED. When the liquid is supplied, the height L1 where the level LH rises up is calculated and inputted to the mechanism 14 by a setter 30 together with a switch valve opened. Meanwhile the liquid is discharged after a liquid level minus L2 is decided and inputted to the mechanism 14 by the setter 30, a circuit is switched to set up a circuit of the motor 12, and an open/close valve is opened.

IPC: F42B3/04
Filed: 1992-05-11
Abstract: PURPOSE: To provide an ignition assembly which stably activates an inflatable safety device. CONSTITUTION: The ignition assembly 358 has an actuation piston 362, percussion primer 366 and ignition material 370 isolated by a retention pin 402. When a sufficient force is exerted on the actuation piston 362, the retention pin 402 fails such that the actuation piston 362 moves toward the percussion primer 366 and impacts the same. As a result, the propellant 334 within a gas generator 326 is ignited. The resulting propellant 334 gases are introduced to a prescribed direction. The projectile 294 to impart the actuation piston 362 has a role of breaking a closure disk 282. Stored gases are supplied to an enclosure prior to the gases of the propellant 334 by the breaking of this closure disk 282. The projectile 294 breaks the closure disk 282 in a manner as to avoid the generation of splinters from the closure disk 282.  Then, the closure in the inflatable safety device by the splinters of the disk 282 is prevented and the safety of the operation of the inflatable safety device is assured.
