Title: Vacuum valve
Inventor: OSAWA YUKIO
IPC: H01H33/66
Filed: 1997-12-25
Abstract: PROBLEM TO BE SOLVED: To enhance strength of a longitudinal magnetic field in a distance gap, and uniformly distribute its longitudinal magnetic field by forming a coil reinforce by a cylinder part and a bottom in a cup shape, bonding the bottom to a coil part, and covering a fixed or movable rod at the cylinder part. SOLUTION: A coil reinforce 17 is constituted of a cylinder part 17A and a bottom 17B. The bottom 17B is bonded with a coil part 10, and a fixed rid 3A is covered with the cylinder part 17A. On the other hand, the coil reinforce 36 is constituted of the cylinder part 36A, and the bottom 36B, the bottom 36B bonded with the coil part 10, and the fixed rod 3A and a bellows 5 are covered. The coil reinforces 17 and 36 are formed in cut shapes, thereby the circumferential part is made to stand up, and mechanically very strengthened. Therefore, the material thickness of the coil reinforces 17 and 36 can be thinned, and an electric transmission resistance of the coil reinforces 17 and 36 is reduced. Thereby, a conductive current component flowing the coil part 10 side increased, and thus, the longitudinal magnetic field in an opening gap 29 is increased.

Title: Analyzing method for concentration of lithium in lithium niobate
Inventor: TERAJIMA AKIRA
IPC: G01N21/00
Filed: 1991-12-27
Abstract: PURPOSE:To analyze concentration of lithium with high accuracy by calculating a complete coupling length from a branching ration of intensities of light measured by the use of an optical waveguide-type directional coupler. CONSTITUTION:A plurality of directional couplers are formed out of optical waveguides 8 on a single crystal 9 of lithium niobate. Mutual acting parts 6 of the couplers are slightly different in length while a gap 5 and gradually approaching parts 7 are kept constant. In the directional couplers, an intensity P3 of an output 3 and an intensity P4 of an output 4 when the light enters from an input 1 (or 2) are measured by detectors 10, thereby to obtain a branching ratio eta (L) of the light intensities. A complete coupling length Lc is obtained from the measured branching ratio (L) according to the method of least squares. If only a calibration curve indicating the dependency of the complete coupling length on the concentration of lithium is obtained beforehand, a concentration of lithium in lithium niobate is highly accurately analyzed by obtaining the coupling length Lc.

Title: Engine room for forklift
Inventor: MIKI OSAMU
IPC: B60K11/06
Filed: 1991-12-26
Abstract: PURPOSE:To provide a forklift engine room enabling the sufficient cooling of an oil tank while preventing dust from being sucked into an engine room and noise from leaking outside from the engine room. CONSTITUTION:The lower part of an engine room 20 is shielded by a sound arresting bottom plate 113. The side face of a vehicle is provided with an outside air inlet 23 so as to provide outside air inlet passages 241, 242 communicated with the engine room 20 through the wall surface of an oil tank 26. At the engine operating time, outside air 8 is sucked in from the outside air inlet 23 and led into the engine room 20 through the outside air inlet passages 241, 242. The outside air 8 thereby takes heat away from the wall surface of the oil tank 26. Because of leading the outside air 8 in from the side face of the vehicle, dust does not easily enter the engine room 20. In addition, the leak of noise is prevented by the disposition of the sound arresting bottom plate 113.

Title: Gypsum board and nail exclusive to light ceiling
Inventor: SUEOKA HEIICHIRO
IPC: F16B15/04
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To fix a nail in the same way as a screw only by driving the nail by forming a specific number of leg tips. SOLUTION: A nail 1 is perceived with two tips. This nail 1 is driven by boring two holes in the light ceiling. Then, a distance between two points of the holes bored in the light ceiling does not change, and since a branched part of the nail 1 gradually narrows in a Y shape, the leg part expands at a obtuse angle. Legs largely open as this branched part approaches the light ceiling. Thus, it can be made nonextractable by expanding the leg part to an obtuse angle only by driving force by forming the leg part on the tip of the nail 1 into two pieces. A construction period of light ceiling work can be largely shortened by executing this nail 1 by a nailing machine.
