Title: Millmeter wave generator
Inventor: SHIMOTSUMA TAKASHI
IPC: H01J25/00
Filed: 1990-05-14
Abstract: PURPOSE:To restrain generation of unnecessary modes by providing through the wall between a collector electrode and an output window slits such that the angle formed between the longitudinal direction of each slit and a pipe axis is less than that formed by the pipe axis and the direction of high frequency current, and hermetically sealing the outer peripheral portion of each slit with a manifold. CONSTITUTION:Unnecessary residual gas in a collector electrode 4 is allowed to pass through each slit 10 and is discharged via a manifold 11 and an exhaust pipe 12 at extra high rate and stable oscillation is obtained by this sufficient exhaust. Being provided at a predetermined angle theta to a pipe axis, each slit 10 does not block high frequency current flowing through a pipe wall at whispering/gallarey mode and oscillation mode is not changed to any unnecessary mode. The size, d, l of the opening of each slit is small enough to minimize high frequency leakage. High frequency leakage is damped by a high frequency absorber 14 in the inner wall of the manifold so as to prevent the manifold 11 from becoming a high frequency cavity. This constitution minimizes conversion to unnecessary modes and provides sufficient exhaust conductance and also minimizes high frequency leakage.

Abstract: PURPOSE:To prevent generation of dimensional error which is liably generated on a hot plate side of a calcined body by placing an uncalcined molded body of starting material powder on a hot plate interposing a dummy consisting of a same material, then, executing calcination and sintering. CONSTITUTION:An uncalcined molded body 12 is prepd. by press molding or injection molding granular inorg. powder as feed material. On the other hand, a dummy D having almost the same shape is prepd. from the same material as the molded body 12. The dummy D is placed on a hot plate (tray) 11 and the uncalcined molded body 12 is placed thereon and the body is calcined and sintered at 500-2,000 deg.C to form the molded glass ceramic body. The uncalcined body shrinks by the heat treatment but the side of the hot plate 11 contacting with the dummy D is prevented from shrinkage by the friction of the hot plate with the dummy. On the other hand, a free end of the dummy causes predetermined shrinkage and deformation. Therefore, the uncalcined molded body 12 placed on the free end of the dummy D causes shrinkage with a fixed proportion over the whole length. Therefore, a sintered body having a predetermined shape and dimension is obtd.

Title: Liquid interface detector
Inventor: KONISHI SATOSHI
IPC: G01F23/24
Filed: 1984-06-15
Abstract: PURPOSE:To enable liquid interface detection with a high safely level, by constantly applying a predetermined pulsed voltage between electrodes in a detecting section, and detecting a resistivity. CONSTITUTION:In actual use of an interface detector 57, an oil-water mixture is supplied to an oil-water separator 12 from an oil-water mixture tank 60. The water in the separator 12 is discharged into a water-storage tank 15 through a pipe 16 by an amount corresponding to the amount of the oil-water mixture supplied. In an early stage of the supply of the mixture, water along exists in the area between upper- and lower-limit electrodes 20, 21 and a grounding electrode 22. Since water is an electrically conductive substance and has a relatively small resistivity, no interface detection is performed in the detector 57. When the oil-water mixture is further supplied, the oil in the mixture resides in the upper part of the separator 12, and when the interface (a) reaches the lower-limit electrode 21, the resistivity of the mixture existing in the area between the electrodes 20, 21 increases, so that interface detection is performed in the detector 57. In detection, a pulsed voltage is applied between the electrodes 20, 21. Therefore, the oil film on each electrode is broken as a result of a sudden change in voltage, so that it is unnecessary to wipe out the electrodes by hand, and it is possible to effect a continuous liquid interface detection. Since the voltage applied to the electrodes is relatively low, it is also possible to effect interface detection of an explosive gaseous substance.

Thus, the requirement of desiring the AND processing without addition of an AND gate and a NAND gate is realized.
