Abstract: PURPOSE:To generate uniform discharge in an axial direction by specifying the inner size of a cylindrical cavity resonator, increasing a microwave wavelength in a tube representing the microwave electric field distribution of a cavity resonator axial direction to infinitive, and forming a uniform electric field distribution in the discharge tube axial direction. CONSTITUTION:The inner radius (a) of a cylindrical cavity resonator 9 is set to a=lambdao.Pn, m/2pi with first type of Bessel function pn, m (n=1, 2,..., m=1, 2,...) for imparting electromagnetic field distribution existing in the resonator and vacuum wavelength lambdao of used microwave. When the radium (a) is determined in this manner, wavelength lambdag in the resonator tube becomes infinitive, and the axial electromagnetic field intensity of the resonator 9 becomes constant. Thus, uniform discharge can be generated in the discharge tube direction.

Title: Liquid-enclosing vibration-proof device
Inventor: AONO YUKIO
IPC: F16F13/26
Filed: 1982-06-28
Abstract: PURPOSE:To prevent the wide-range transmission of vibration in a device to be used for the mount of an engine by keeping a dynamic spring constant and a damping coefficient together at a high level in the vibration-damping area of low frequency, and at a low level in the vibration-proof area of high frequency. CONSTITUTION:On the basis of the output signal of a control device 12 receiving the signal of the relative displacement between an engine and a car body, a change-over switch 11 switches over a battery 10 connected to a coil 9 between positive and negative poles. In the vibration-damping area of low frequency, an actuator 14 composed of a permanent magnet is moved downward by the coil 9 when an elastic wall 1 is contracted, and upward when extended for increasing the pressure difference between fluid chambers A and B to increase the effect of damping. In the vibration-proof are of high frequency, the actuator 14 is moved oppositely to the above, and the pressure difference between fluid chambers A and B is reduced to reduce the effect of damping.

IPC: C07C1/00
Filed: 1983-06-22
Abstract: PURPOSE:To carry out the selective hydrogenation of an acetylene compound and phenylacetylene in styrene, in liquid phase under atmospheric or pressurized condition, by using a catalyst containing palladium and a VIB-group metal or its salt and supported on alumina. CONSTITUTION:Acetylene compounds and phenylacetylene existing as impurities in styrene useful as a raw material of plastics and other chemicals are selectively hydrogenated in liquid phase under atmospheric or pressurized condition, and removed.

Abstract: PURPOSE:To reduce the variation in the potential of an area opposite a substrate and to reduce shading by superposing a transfer gate pulse upon a transfer pulse applied to a transfer electrode of the 2nd layer. CONSTITUTION:A charge transfer electrode has double-layer electrode structure composed of electrodes 39b and 40b of the 1st layer shown by an alternate long and short dash line and electrodes 39a and 40a of the 2nd layer shown by a broken line. Major parts of the electrodes 39a and 40a are formed on the electrodes 39b and 40b and a transfer gate area 41 and part of vertical registers RM and RN couple with a P well across capacitance. Buried channels right under electrodes are in a depletion state, so the capacity between the electrodes 39a and 40a, and a P well corresponds to the area of the gate area 41 apparently. Consequently, P well variation in a period wherein transfer gate pulses are superposed is small and shading is reduced to an extent where there is no problem.

Abstract: PURPOSE:To enhance a hatching rate of a fishing bait insect while killing small protozoan adhered to the inside of a filter apparatus, by treating the interior of the filter apparatus with fresh water when the capacity of the filter apparatus is lowered. CONSTITUTION:When the capacity of a filter apparatus 1 is lowered, a valve 4 is closed and a valve 8 is opened to discharge the seawater in the apparatus 1 through conduits 15, 16, 18. When the water level of the seawater in the apparatus 1 almost reaches the top part of a filter aid 3, the valve 8 is closed while valves 5, 6 are opened to spray fresh water to the surface of the filter aid 3 from a nozzle 19 through conduits 12, 13. By this washing treatment, the small protozoan adhered to the surface layer of said filter aid 3 dies and discharged out of the system along with the other impurities in the surface layers and washing water through a conduit 11. By this method, the capacity of the filter apparatus 1 is restored and the small protozoan exerting adverse influence on the hatching of a fishing bait insect is allowed to die.
