IPC: H01J63/06
Filed: 1991-02-27
Abstract: PURPOSE:To improve uneven brightness of a flat fluorescent lamp due to linear cathodes by changing the shape of each back electrode. CONSTITUTION:In a flat fluorescent lamp having back electrodes 9 on a back panel 2, the back electrodes 9 are arranged into a pattern of stripes parallel to a plurality of linear cathodes 7 and the orbit of thermoelectrons generated from the linear cathodes 7 is enlarged so as to improve unevenness of brightness of the lamp. Then the back electrodes 9 are arranged at the same intervals as the linear cathodes 7 and between the linear cathodes. When the back electrodes 9 are arranged between as well as just below the linear cathodes 7, the voltage of each of the back electrodes 9 arranged between the cathodes 7 is made higher than that of each of the back electrodes 9 disposed just below the cathodes 7.

Abstract: PROBLEM TO BE SOLVED: To prevent turbid current flowing out of a frame body, by providing nozzles in order to form water streams at an opening formed between side frames of a floating body surrounding a charge opening of soil. SOLUTION: A plurality of nozzles 6 turning toward the inside at a specified angle from the longitudinal direction are provided separately from each other in the vertical direction, in the inside face of one end or both ends of floating side frames 2. And water is jetted out into the space surrounded by the side frames 2 through the nozzles 6 by a pump to form a circulating warer stream from the outside of the side frames to the inside thereof. Accordingly, turbid water is forced to flow down from the bottom face of the side frames 2 and the turbidity in the side frames is attenuated acceleratedly. The structure prevents the turbid water in the side frame brought when soil is charged, from fowing out in accordance with arranging and retracting motion of the preventive device in a soil barge.  In this way, this device prevents turbid water from flowing out of the frame when a soil barge arranges or retracts the preventive frame against turbid water ans also prevents dispersion of the turbidity in water and the bottom of water at the time when soil is charged in the barge.

The thus made separating bodies are placed between pasted positive and negative plates to make an electrode group. After that, the electrode group having a tightening pressure of 5kg/dm<2> is inserted in a container before being heated to 90 deg.C so as to cause the hollow bodies to foam prior to being cooled, thereby increasing tightening pressure given from the retainer to a positive active material. As a result, high tightening pressure can be easily given to the electrode group, thereby enabling the life performance of the electrode group to be improved by increasing its active-material-holding ability.

Title: Vibration generation mechanism by compression liquid
Inventor: FUJII HIDEO
IPC: B44B3/02
Filed: 1993-01-29
Abstract: PURPOSE:To improve reliability of reciprocating movement without requiring a precise work by attaching a thin-plate elastic member on the upper part of a vibration body and supplying air to a pressurized chamber in which a close adhesive member is sealingly formed by its elasticity. CONSTITUTION:When pressurized air is supplied to a channel 11, the pressure in a pressurized chamber 22 increases so that downward force is applied to an elastic member 6 and a vibration body 4 descends. Because of descending of the vibration body 4, a close adhesive member 3 and the elastic member 6 cannot hold the sealed state of the pressurized chamber 22 so that pressure is released to a hollow part 21. When air in the pressurized chamber 22 is released to the atmosphere, the vibration body 4 is pressed by a compression spring 5 so as to regain the original state. Continuous supply of pressurized air forces such an action repeatedly that the vibration body 4 vibrates continuously. Therefore when the tip of the axial part 4A of the vibration body 3 is formed in a conical shape and the tip part is pressed against the surface of a workpiece 30, the surface of the workpiece 13 is plastically deformed and carved.
