Title: Hollow cathode
Inventor: YOSHIKAWA KANZOU
IPC: F03H99/00
Filed: 1983-04-21
Abstract: PURPOSE:To provide with heat shield effect and improve the heating efficiency of the cathode part by a method wherein a keeper surrounding vessel, having another orifice, whose diameter is equal to or larger than the same of the orifice of a keeper electrode, is provided at the side of the outer surface of the keeper electrode. CONSTITUTION:The center of the keeper surrounding vessel 13 is bored with the orifice having the diameter equal to or larger than the diameter of the keeper orifice 6. During heating the cathode until beginning of gas electric discharge, the keeper electrode 12 acts as the first heat shield while the keeper surrounding vessel 13 acts as the second heat shield. When the electric discharge is being continued, the keeper electrode 12 heats by the electronic impact from plasma, therefore, the heat, generated in the keeper electrode 12, may be used effectively for the heating of a cathode disc 3 or an electronics emitting body by the heat shielding effect of the keeper surrounding vessel 13.

Abstract: PROBLEM TO BE SOLVED: To simply and certainly keep pH accuracy without allowing a user to feel troublesomeness in calibration by performing the calibration of a pH value by using a washing soln. as a reference soln. at a time of the washing with the washing soln. SOLUTION: A pH sensor 9 measures a pH value of water electrolyzed after purification and the regulation of the electrolytic current in an electrolytic cell 5 is performed so that the measured value becomes a preset pH value and the pH value is displayed on a display device 8. When an alkali ion water maker is used for along period of time, the detection accuracy of the pH value is lowered by bonded matter. For example, internal washing is performed by a washing soln. such as citric acid or the like about once a year. By preliminarily prescribing the pH value of the washing soln.,, the calibration of the pH value using the washing soln. as a reference soln. can be performed simultaneously at a time of washing.  The operation for the calibration is performed according to the control program preset to a memory part to be stored therein by the pH calibration part in the CPU of a microcomputer 10.

Abstract: PURPOSE:To make it possible to quickly and certainly take out piledly housed parts one by one by separating molded parts being apt to charge with static electricity one by one through a parts separating means, and then attractingly holding the parts by an attracting means to draw it out from a stocker. CONSTITUTION:An attracting means 4 ascends toward a part in the lowest layer of molded parts piledly housed in a stocker to attract the bottom of the parts in the lowest layer through its tip, and after ascending slightly, stops at a position where a separating claw 2 becomes free from a load. Next, after a separating means 3 moves in a direction shown by the arrow B, the means 4 lowers, and stops temporarily when it has attained a position where the separating claw 2 can be inserted between the parts to make the claw 2 enter between the two parts. The means 4 then lowers as it attractingly holds only the part in the lowest layer, and stops temporarily when the part has attained a receiving face of a guide rail 5. At this time, a shutter 7 rotates in a direction shown by the arrow C' to enter between the parts 6a, 6b, and the means 4 is thereby released from attracting action to lower to the lower limit position.

Title: Dose measuring method
Inventor: YAMASHITA MIKIO
IPC: G01T1/20
Filed: 1988-03-26
Abstract: PURPOSE:To execute the measurement with high reliability by using a comparatively simple measuring system by attenuating optically a scintillation which is generated by a fact that a scintillator receives a radiant ray and converting an obtained optical pulse to an electric pulse. CONSTITUTION:When a radiant ray has been radiated, a scintillator 1 generates one after another at a random time a scintillation of light intensity corresponding to magnitude of energy which has been given by the radiant ray. These scintillations are sent to an optical attenuator 3 through an optical fiber light guide 2, and made incident on a photodetector 4 after its light intensity has been reduced. The number of pieces per unit time of an electric pulse outputted from the photodetector 4 is proportional to the total light emission quantity of the scintillations, that is, a dose which the scintillator 1 receives per unit time. Therefore, when this electric pulse is amplified by a proportional amplifier 5, allowed to pass through a wave height analyzer 6, and thereafter, made incident on a counter 7 and the number of electric pulses is measured, the quantity of radiation which the scintillator 1 has received can be determined.
