Abstract: PURPOSE:To shorten a distance between electrodes, while maintaining a practical brightness, so as to aim at miniaturization, in the captioned fluorescent lamp utilizing positive column emission, by providing a means for narrowing discharge on the front surface of a cathode filament. CONSTITUTION:The captioned fluorescent lamp is formed such that discharge gas is charged inside a glass bulb 1 where the tip part thereof is formed in an approximately bulb shape and the inner surface thereof is coated with a phosphor 2, while an anode 4 being positioned at the vicinity of the tip part is opposed to a cathode filament 3. Further, on the front surface of the cathode filament 3, a ring for narrowing discharge is arranged such as being electrically floated. And, the recombination of electrons to mercury ions is preferably performed so as to promote the formation of a positive column so that Farady dark space is extremely shortened. Therefore, a distance between electrodes is remarkably shortened, thereby the miniaturization of the lamp can be performed.

Title: Optical information communication equipment
Inventor: FUKUI HAJIME
IPC: H04N5/00
Filed: 1998-09-01
Abstract: PROBLEM TO BE SOLVED: To control the delay of light emitting signals from a flash light emitting tube to a transmitted information signal almost constant. SOLUTION: High voltage is charged to main capacitor 2 by a circuit including a DC-DC converter 1 and transistors 5 and 10 and the voltage is applied to an Xe tube 20 to make the pipe 20 emit light by a light emission control means consisting of a trigger capacitor 15 and a trigger transformer 16. At the time, though a transmitting timing signal of a fixed period is formed at a microcomputer 30, a waiting time until giving an actual trigger signal is decided by the value of a light emitting interval counter K showing how many pulses are inserted between with the former light emission of the tube 20 and the on-timing of IGBT 21 is decided based on this counting result so that the scheduled light emitting interval of the tube 20 may be nearly constant. Thus, the variation of light emitting pulse intervals is prevented and optical information is precisely transmitted.

Abstract: PROBLEM TO BE SOLVED: To obtain a measuring method in which the position and the degradation degree in the degraded point of a degraded-phase cable are detected easily in a live-conductor state. SOLUTION: A sound-phase cable 11 and a degraded-phase cable 12 indicate existing lines of the same length, they are laid in parallel, and a degraded point F exists in the degraded-phase cable 12.

During the control mode, it is effective to conduct in a closed condition in a device controller into which all data of the device is inputted. Its operation is conducted by a host computer. During the standby mode, respective elements of the device will not move, therefore, detecting oil leakage is a main object as detection items for a hydraulic system. Abnormality is detected based on the assumed oil pressure of a hydraulic sealing type damping device and temperature monitored in the building.

IPC: C02F11/12
Filed: 1998-08-12
Abstract: PROBLEM TO BE SOLVED: To dehydrate sludge to a specified water content in a short time without using a flocculant at all by adjusting the temp. of steam coming from a boiler to a specified temp. with a total-enthalpy steam generator and blowing the steam directly into sludge in a vacuum tank to quickly increase the sludge temp. to thereby convert the sludge into an association colloid.

Title: Mechanism having engageable gear member
Inventor: AASAA JIEEMUZU FUAI
IPC: F16H1/08
Filed: 1990-09-28
Abstract: PURPOSE: To provide a mechanism having a meshing gear member and rotating in the same direction by producing a slide on a contact flank surface of a member on one side by a flank surface due to shapes of two flank surfaces and a pitch of teeth and the rotation of a member on the other side. CONSTITUTION: When a gear member 2 is rotated, the rotation transmits spiral winding of a tooth 4 in one direction, namely, from right to left as shown in the drawing along an engaging region 6. This causes the engagement of a sharply inclined front flank surface 7 of the tooth 4 and a sharply inclined rear flank surface 9 of a tooth 5. The flank surface 7 slides on the flank surface 9 by rotating in the direction of transmission of spiral winding due to a pitch and a shape of teeth. This travel brings about rotation torque acting on a member 3 so that a member 3 and the member 2 are turned in the same direction. When the gear member 2 drives the gear member 3, a small space is produced between gently inclined flank surface 8 and 10. For this reason, they do not interfere with power transmission.  However, when the direction of drive of the gear member 2 is reversed, the flank surface 8 of the tooth 4 presses the flank surface 10 of the tooth 5, but the gently inclined flank surfaces are shaped so as to prevent the transmission of driving force form the member 2 to the member 3.

Abstract: PURPOSE: To provide a long sevice life scintillation camera plate assembly to house a sicintillation crystal such as thallium-active sodium iodide by respectively sealing an outer ring, a transparent plate of its front face and a cover plate of a rear face by frit. CONSTITUTION: An outer ring 12 is composed of a front face on which an optically transparent plate 14 is installed and a rear face covered with a cover plate 16, and a circular groove 18 is notched on the front face.

Grooves 18 and 42 are notched on the rear face of the outer ring 12, and a depth of the groove 42 is slightly larger than a thickness of the plate 16. This groove flows out excessive solder and frit 46 or the like from a scintillation plate of a main body. Distortion of the light on an interface of materials of a different type can be prevented by applying an optical coupler 50 having a refractive index close to a refractive index of the plate 14 to an inside surface of the plate 14.
