Title: Gas discharge tube
Inventor: KIKUCHI NAOYA
IPC: H01J11/14
Filed: 1999-09-24
Abstract: PROBLEM TO BE SOLVED: To provide a gas discharge tube in which decrease in luminance, luminous efficiency, and mechanical strength that may be caused by securing a discharge route is suppressed. SOLUTION: A discharge route 44 is spatially divided into four small chambers 26 owing to dividing walls 25 which organize an inner surface of a luminous room 12. However, discharge between a cathode 42 and an anode 28 is electrically connected between the small chambers 26 owing to continuously placed independent electrodes 38 between the small chambers. Therefore, discharge through the dividing walls 25 doesn't occur even though voltage is applied between the cathode 42 and the anode 28, however, discharge occurs between the small chambers 26 owing to a difference of electric potentials between the independent electrodes 38 and other electrodes put in the chambers 26. Therefore, one substantially continuous discharge route 44 can be formed in the luminous room 12 without keeping the spatially continuing discharge route 44 by making through holes on the dividing walls 25.  As it is not necessary that the through holes should be made on the dividing walls 25, lowering of luminance, luminous efficiency, and mechanical strength that may happen when keeping the discharge route 44 can be sufficiently suppressed.

Abstract: PURPOSE:To dispense with an inspector visually observing the generation of air bubbles and to simplify the mechanism of a robot hand part, by allowing air bubbles generated when an airtight container is sunk in water to pass through the center hole of a bubble gathering plate. CONSTITUTION:A tank 4 is grasped by the arms 3 of a robot hand 2 to be sunk in water and, when air bubbles 6 are issued from the tank 4 sunk under the surface 5 of the water, said air bubbles 6 are gathered by a bubble gathering plate 8 and pass through the hole 8a thereof to rise. The light emitted from a floodlight projector 9 is received by a light receiver 10 as it is when there are no air bubbles 6 in the path of said light and transmitted through an optical fiber cable 11 to be converted to an electric signal. When the air bubbles 6 are present in the path of the light, said light scatters by the air bubbles 6 and does not reach the light receiver 10 and, therefore, the electric signal is interrupted occasionally. This state is detected to judge whether the air bubbles 6 are generated from the tank 4. When the air bubbles 6 are generated, the tank 4 is detected as an inferior product and an alarm is emitted.

Title: Areodynamic braking parachute
Inventor: FUJISE MORIMASA
IPC: B64D17/80
Filed: 1993-10-28
Abstract: PURPOSE:To enhance braking force even if an area of a parachute is the same with a conventional one by rotating the parachute, preventing a twist of a parachute tensioning rope by a slidingly movable part inteposed between the parachute and an object to be controlled, and transmitting only the braking force to the object to be controlled. CONSTITUTION:A parachute 1 is taken out by a pilot chute 7, and is expanded. The parachute 1 is made discontinuous in the circumferential direction, and is in rotational symmetry with a riser 4 as the center line, and has radial-shaped clearances 12, or holes, pleats or the like, and this discontinuous part forms an element respectively as a rotary wing, and rotates. By this rotation, the parachute 1 receives wind resistance excessively by advance speed of the parachute and rotational speed in the perpendicular tangent direction. Though lift acts on the parachute 1 by a wind blowing into this parachute 1, this lift acts so as to reduce the advance speed of the parachute as well as to promote the rotation of the parachute 1. Since the parachute 1 is installed in a machine body through a thrust bearing 5, a phenomenon that a rope 3 is twisted by the rotation and the parachute 1 is closed and braking force is reduced, does not happen.
