Title: Vibration monitoring apparatus
Inventor: FUJIWARA NORIYUKI
IPC: G01M99/00
Filed: 1983-10-31
Abstract: PURPOSE:To monitor the vibration and the phase angle in all the regions of number of rotation, by performing shaft eccentricity measurement, shaft vibration measurement, and phase angle measurement by using a number of rotation sensor, patterning the number of rotation and shaft displacement, and performing the measurement. CONSTITUTION:With the rotation of a rotor 1, a gear 2 is rotated. A number of rotation sensor 3 detects the protruded parts and recess parts of the gear 2. A number of rotation detector 16 outputs a speed signal. A vibration tester 17 outputs a shaft vibration level signal. The number of rotation signals, the shaft displacement signal, and the parameter signals from a speed-vibration level pattern setting device 18 are compared and computed by a speed-vibration level operator 19. When the deviation signal becomes larger than the output of a vibration-level warning setting device 25, a warning device 27 is operated. Meanwhile, in an eccentricity-vibration angle measuring device 29, the reference signal of a vibration phase signal of a position-detecting waveform shaping device 28, which is obtained from rotation marks 14, gives the phase angle to the output of a number-of-rotation detecting waveform shaping circuit 15. The output is superimposed on the vibration level of the vibration detector, and the phase angle is displayed on a display device 30.

Further, the semiconductor and the upper electrode are evaporated and removed by irradiating this place with a YAG laser spot. Thus, the semiconductor 4 is exposed at the side surface or the surface 20. Thereafter, this PVC1 is coated with an Si nitride insulator 21 over the entire surface thereof, resulting in the formation of a passivation film. Moreover the upper surface thereof is coated with polyimide resin, thereby improving the moisture resistance and preventing the leakage current on the I-layer side surface between the P-N junction at this trimming part.

Filed: 1995-08-14
Abstract: PROBLEM TO BE SOLVED: To separate cups satisfactorily, by forming the cups so that, when the two thermal insulation cups are superimposed, the top of the spacer of the lower cup comes into contact with the face of the lower end of the upper cup. SOLUTION: At the lower end of the main body of a cup, a spacer 42 comprising a ringlike projection is provided round a bottom wall 16. The spacer 42 is formed by bending a middle part connecting a cylindrical leg 44 and a circular flat part 46. The leg 44 of the bottom wall 16 is surrounded by the turned-up fold 52 of the lower end of a side wall 14 all the way round it, both sides of the leg 44 are stuck to it with glue, and sealability is therefore secured. When the two cups 10 are superimposed one on top of the other, the top of the spacer 42 of the lower cup 10 comes into contact with the face of the lower end of the upper cup 10. At the time of the contact, the outside diameter of the lower end of the upper cup 10 is made almost equal to the inside diameter of the lower cup 10 positioned opposite it or made slightly smaller than this.  Therefore, because a static friction force which occurs between the cups 10 is small, the upper cup can be pulled from the lower one with a small force.
