Title: Detection method for partial discharge of power cable
Inventor: TASHIRO TSUTOMU
IPC: G01R31/12
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To improve detection accuracy of partial discharge, by arranging a pair of foil electrode on external sheath of power cable having a copper tape shield layer, arranging a high frequency iron-core between electrodes, and increasing the impedance of the shield. SOLUTION: When partial discharge occurs in an insulator 2 between a high voltage conductor 1 of CV cable 10 and an external semiconducting layer 3, reciprocal current based on the partial discharge flows between the conductor 1 and a copper tape shield layer 4. This current flows as sheath current along the shield layer 4, and the shield layer 4 has an increased impedance by a high frequency iron-core 7, and by this, the electric potential difference induced between both ends of a detection impedance 8 increases. When the shield layer 4 is normal, the sheath current flows in the longitudinal direction of the cable 10. When looseness and play exists in the shield layer, contact resistance increases and the sheath current spirally flows in the circumferential direction of the cable 10.  In this case, the electric potential caused between the both ends of the detection impedance 8 gradually becomes large and the detection accuracy of the partial discharge is improved.

Title: Ion implantation method
Inventor: MIYAGAWA RYUHEI
IPC: H01L21/266
Filed: 1990-11-26
Abstract: PURPOSE:To reduce the charge-up at ion implantation by providing a thin conductive layer on the resist of an insulator, and letting the static electricity, which is generated during ion implantation into a wafer, flow to the grounding point at the wafer end easily through this conductive layer. CONSTITUTION:After formation of a thin oxide film 12 and a positive resist layer 13 on a wafer 11, the layer 13 is patterned, and also an aluminum film 14 is formed all over the surface of the wafer 11 by sputtering. Next, ion implantation of B ions or BF ions is performed, and then the film 14 and the layer 13 are exfoliated, with which ion implantation is finished. What is more, the film 12 suppresses the damage on the element, made on the bulk wafer or the wafer, caused by ion beams 15, and prevents the influence on the element by the knock-on phenomena of an aluminum film 14. And by the film 14 provided on the layer 13, it has the effect of the charge-up of the wafer 11 by the ion beam at ion implantation being reduced, so the uniformity in ion implantation is not disturbed, and besides the problem on reliability referring to the element breakdown by static electricity can be solved.

Title: Ultrasonic therapeutic unit
Inventor: YAYAMA TOSHIHIKO
IPC: A61F7/00
Filed: 1997-11-06
Abstract: PROBLEM TO BE SOLVED: To make ultrasonic vibration effectively act on the human body, and enhance a therapeutic effect by installing a ferrite body composed of a thickness according to an ultrasonic oscillation frequency in an ultrasonic vibrator around which a coil connected to a high frequency oscillator is wound. SOLUTION: An ultrasonic vibrator 5 around which a high frequency coil 3 is wound is built in an ultrasonic therapeutic unit 1, and a high frequency oscillator is connected to this high frequency coil 3. When a high frequency pulse is impressed on the high frequency coil 3 from the high frequency oscillator, the ultrasonic vibrator 5 oscillates, for example, ultrasonic vibration of necessary output (intensity) in a necessary frequency of 1 MHz to 10 MHz. A ferrite body 9 is adhered to a front face of the ultrasonic vibrator 5 through an elastic thin plate 11.  When ultrasonic vibration is generated from the ultrasonic vibrator 5 by impressing a high frequency pulse on the high frequency coil 3, the ferrite body 9 generates new ultrasonic vibration by performing amplitude vibration by propagated ultrasonic vibration, and makes it act on the human body through a metallic body 13 and a covering elastic member 15.

Title: De-excited operation type electromagnetic brake
Inventor: MURASE SHINKO
IPC: F16D55/00
Filed: 1996-11-19
Abstract: PROBLEM TO BE SOLVED: To suppress the vibration when a brake is applied and prevent a contact sound and the damage by shock force by providing an integrally molded rubber film at the contact section of a collar with an armature. SOLUTION: When no current is fed to an exciting coil 2, a disk 5 is pressed to a side plate 7 via an armature 4 by the pressing force of multiple coil springs 10 stored in a field core 1. The disk 5 generates torque by the frictional force on the contact faces of the armature 4 and the side plate 7 as the brake state. When a brake is applied, the armature 4 is moved in the peripheral direction to generate a contact sound, and a collar 8 might be damaged and deformed by strong shock force. A collar 21 provided with an integrally molded rubber film 21A on the inner and outer peripheral faces is employed in place of the conventional collar 8. The contact sound and strong shock force can be suppressed by the damping effect of rubber when a brake is applied.

Title: Method and apparatus for measuring polarization mode dispersion utilizing four polarization incidenttype fixed analyzer method
Inventor: ASO OSAMU
IPC: H04B10/2569
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To correctly measure and evaluate a polarization mode dispersion, by distinguishing a mode-coupling state of an optical fiber to be measured. SOLUTION: A spectrum of an emitted light (first spectrum) penetrating from one side to the other side of an optical fiber to be measured and, a spectrum of a emitted light (second spectrum) penetrating from the other side to the one side of the optical fiber are measured. A first and a second polarization mode dispersion values (PMD values) are obtained from the corresponding spectrums. Whether or not waveforms of the first and second spectrums, and the first and second PMD values agree with each other within a preset range is detected by a reversibility judgment part 15. When the waveforms and PMD values agree respectively with each other, it is judges as a strong/weak mode- coupled state. If the waveforms and PMD values do not agree, it is judged as an intermediate mode-coupled state, whereby a PMD evaluation is discarded.  In the strong/weak mode-coupled state, whether it is a strong mode or weak mode is distinguished from whether the waveform of each spectrum is a sine. The PMD is evaluated correspondingly to each mode.
