Filed: 1997-01-24
Abstract: PROBLEM TO BE SOLVED: To prolong a service period of a radiation source by making it possible to obtain a prescribed strength of the radiation source even after the half-life of the radiation. SOLUTION: A radiation source 1 consists of a line source 2 such as radioactive<68> Ge and a case 3 for encapsulating the line source 2. After inserted into the case 3, the line source 2 can be encapsulated into the case 3 by screwing a cap 4 into the case 3. The radiation source 1 is equipped with two holders: one case made of tungsten and another made of stainless. At the beginning of use, the line source 2 is inserted into the tungsten case to use the radiation source. When radioactivity decays to half its original level, the line source 2 is taken out from the case 3 and is inserted again into the stainless case to use the radiation source. Consequently, the strength of radioactivity is twice or more at that time and the radiation source can be used further.

Title: Noise elimination device
Inventor: KANAI HIROFUMI
IPC: G11B20/02
Filed: 1990-01-24
Abstract: PURPOSE:To eliminate noise without malfunction by providing a pulse width measurement means, a comparison means, a storage means and a control signal output means. CONSTITUTION:The pulse width of inputted pulses for controlling P1 and P2 is measured by the pulse width measurement means 13 and 14. When 1/2 of the width of the pulse for controlling is regarded as a reference, for example, and the pulse having the narrower width than the reference is inputted, the comparison means 15 makes the storage means 17 store the width value of the pulse as a noise width value. The control signal output means 16 compares the pulse width value of the pulse for controlling with the noise width value, judges whether the inputted pulse is the noise or not and outputs a control signal. Since the noise width value is updated every time that the pulse for controlling is inputted, the noise is eliminated corresponding to the change of a peripheral environment.

Abstract: PURPOSE:To separate a solvent having a smaller specific gravity than water from water dispersed in said solvent effectively and with high precision by providing a safety outlet of the solvent to above an outlet of the solvent in a water separator constructed by using a membrane which can permeate the solvent alone selectively. CONSTITUTION:A mixed soln. is poured into a water separator 1 from an inlet port 2 of a mixed soln. of a solvent and water. The permeation of the water into the inside of a filter cartridge 5 prepd. from a pleated water-repellent membrane is inhibited and is separated to below the cartridge, and discharged from a water discharging port 6. On the other hand, the solvent 7 is separated by the filter cartridge 5, permeates the inside of the filter cartridge 5 and recovered through an outlet 6 of the solvent into a tank for reusing the solvent. Even if a level 9 of the solvent rises due to clogging of the cartridge 5 by dusts in regenerated solvent, the solvent can be flowed out through a safety outlet 4. Thus, the water separator is prevented from being sealed with liquid.
