Title: Examination method of nuclear magnetic resonance examination apparatus
Inventor: SHUDO TAKESHI
IPC: A61B10/00
Filed: 1987-12-02
Abstract: PURPOSE:To obtain a sharp image free from the formation of a low contrast image, by mounting an absorbing material for absorbing either one of a high frequency electromagnetic field and a high frequency magnetic field generated at the resonance signal generating part of an examinee close to the coil arranged to the outer peripheral surface of a detection probe. CONSTITUTION:The detection probe 3 mounted on an examinee 4 is mainly constituted of a bobbin 3a and coils 3b, 3c and the arm 4a out of a measuring concern region is surrounded by an absorbing pad 9 capable of shielding a high frequency magnetic field to attenuate the generation of the resonance signal from the region concerned. The absorbing pad 9 is formed by packing a flexible strip like conductive material 9a in a flexible material composed of an electric insulating material and providing fasteners 9c capable of winding the absorbing pad to both end surfaces of said conductor 9a. The shield effect of an unnecessary region becoming a high signal can be sufficiently developed when frequency (f) is 20 MHz, the material is composed of copper or aluminum and a thickness is set to 50mum or more and the compression of contrast can be eliminated. Since the signal of the region of the examinee 4 not surrounded by the absorbing pad 9 reaches the coils 3b, 3c at they are, the normal formation of an image becomes possible.

Title: Dehydration of sludge
Inventor: TANABE SHIGERU
IPC: C02F11/14
Filed: 1986-12-22
Abstract: PURPOSE:To reduce the water content of a dehydrated cake, by adding an amphoteric org. polymer flocculant to org. sludge and dehydrating the resulting mixture. CONSTITUTION:An inorg. flocculant such as caustic soda, caustic potash or slaked lime is added to org. sludge so that a pH value becomes 5-8 after addition.

Abstract: PROBLEM TO BE SOLVED: To protect a sliding from adhesion part by arranging air ejection ports for ejecting high temperature air toward an shaft part of an inlet guide blade, on an outer periphery part of an intermediate casing of an axial flow compressor provided with a stationary blade variable mechanism. SOLUTION: A multiple air ejection ports 5 are drilled on a semicircular arc shaped inner circunmferential side of an air ejection pipe toward an inlet guide blade shaft. An air feed nozzle 6 is arranged on one position of the air ejection pipe 3, and is communicated with a delivery port through a blade 9. When the valve 9 ion a pipeline communicated with the delivery port of an axial flow compressor is opened, the two ejection pipes 3 which are vertically arranged on a front part of the inlet guide blade shaft at an outer periphery of an intermediate casing 1 is communicated with the delivery port of the axial flow compressor through the air feed nozzle 6 and the valve 9, air delivered at a high temperature by a pressure difference flows into the air ejection pipe 3, and air is ejected from the air ejection ports 5.  Water drops stuck on the outer peripheral side of the intermediate casing 1 is dried by hot air if its air delivered with the high temperature, or is blown away. It is thus possible to prevent a sliding part from adhesion caused by a clay shape displayed by mixing sliding powder with dust in a room.

Filed: 1989-11-28
Abstract: PURPOSE:To improve the reliability of detection by performing a vector product operation on the basis of a field flux vector and armature current vector and by detecting the generated torque of a synchronous motor by means of an instantaneous value. CONSTITUTION:A d-axis field flux signal and q-axis field flux signal are generated on the basis of a rotation angle detector 11 for detecting the magnetic pole angle of the revolving field rotor 1F of a synchronous motor SM. A d-axis armature ampere-turn signal and q-axis armature ampere-turn signal are generated on the basis of the output of a current detector 13 for detecting the armature current of the synchronous motor SM. Also, the value of the d-axis field flux signal and that of the q-axis armature ampere-turn signal are multiplied by a multiplier 18, and the value of the q-axis field flux signal and that of the d-axis armature ampere-turn signal are multiplied by a multiplier 19. Both multiplied values are added by an adder 20 for the purpose of performing a torque detection. Thus, the generated torque of the synchronous motor can accurately be detected with a high reliability without any mechanical torque transfer means.

Title: Formation of wiring and device therefor
Inventor: MIZUKOSHI KATSURO
IPC: H01L21/3205
Filed: 1987-12-07
Abstract: PURPOSE:To make it possible to surely attain the identification and repair of a defective place in a semiconductor device by a method wherein conductive substances are filled in a contact hole formed at a place where a wiring is to be additionally formed while a laser irradiation and vibration are applied to the device in a CVD gas-containing atmosphere and the wiring is additionally formed. CONSTITUTION:When conductive substances 48 are filled in a contact hole 6, CVD gas is decomposed and generated gas is exhausted outside of the hole 6. Fresh CVD gas takes the place of this and is fed to the slight gaps between the substances 48 an an Al wiring 4 of a semiconductor device 1 and so on as well. Thereby, the conductive substances are filled minutely and the specific resistance is reduced. Moreover, an excitation is executed in the direction rectangular to the scanning direction (a) of a laser beam 35 at the time of formation of the wiring and the wiring width is made large. On the other hand, when an excitation is executed in the same direction as the scanning direction of the laser beam 35, the film thickness of the wiring layer can be made thick because the laser beam 35 is superposed and irradiated on the already deposited wiring. By these facts, the sectional area of the wiring 4 is increased and the wiring resistance can be reduced.
