IPC: G01M1/14
Filed: 1981-08-31
Abstract: PURPOSE:To simultaneously measure the unbalance quantity of centrifugal force and the angle of revolution from the standard position with a simple work by using a cathod-ray tube oscilloscope. CONSTITUTION:A vibrometer 12 for detecting the vibration of a bearing part 11 is connected to the input side of an oscilloscope 8 through an amplifier 9, and a filter for fetching the component of rotational frequency of a rotary shaft 3 and also a rotation detector 14 for detecting the angle of revolution of the rotary shaft 3 from the detection of a standard position mark 13 fitted to the rotary shaft 3 is directly connected to the input side of the oscilloscope 8. After removing weights 5, 6 for compensation, a rotary body 1 is rotated and the amplitude a1 and the angle phi of revolution at the maximum vibration are read out from the waveform of the oscilloscope 8. Subsequently the weights 5, 6 having the same and known mass are fitted and fixed to/in a groove 4 at the symmetrical positions turned from the standard position respectively by the angle phi of revolution and the amplitude a2 at the time is read out from the oscilloscope 8. On the basis of these results of measurement, the unbalance quantity of centrifugal force and the angle of revolution from the standard position are found by operation.

Filed: 1991-05-14
Abstract: PURPOSE:To prevent the occurrence of wrinkles on a recording sheet which is adsorbed to a dielectric sheet by making an electrostatic inducing force which is applied to the trail end part of the recording sheet less strong than the force which is applied to the leading end part of the recording sheet. CONSTITUTION:A controlling means 6 is installed between an adsorption corotron 2 and a D/C power supply 21. A current value flowing into the corotron 2 is attenuated by the controlling means 6 at a prescribed timing, or the current is cut-off by the controlling means 6. The prescribed timing is obtained after the leading end of the recording sheet 5 is made to abut on the dielectric sheet 1 and before the trail end of it is made to abut on the sheet 1. The recording sheet 5 is surely adsorbed to the dielectric sheet 1 within the extent only from the leading end of the recording sheet to a prescribed area in such a way, and the recording sheet 5 is not adsorbed to the dielectric sheet 1 within the extent from the area to the trail end, or the sheet 5 is adsorbed to the sheet 1 with some degrees of freedom. Thus, the recording sheet 5 is pressed and extruded by a deflector roll 3 from the leading end to the trail end, and then, the sheet 5 is brought into tight contact with the dielectric sheet 1.

IPC: C09D167/00
Filed: 1994-06-20
Abstract: PURPOSE:To obtain a snow-adhering-preventive coating material excellent in both snow-adhering-preventive properties and weathering resistance. CONSTITUTION:This material is one comprising a mixture of a powdered low molecular weight tetrafluoroethylene even the terminals of which are fluorinated and which has an average molecular weight of 500-20000 with at least one resin selected from among a fluororesin, an acryl silicone resin, a polyester resin and a silicone resin and having a surface free energy of 21mN/m or below on the coated surface. Because the fluorine atoms constituting tetrafluoroethylene are highly electronegative, form strong bonds and form a molecular surface very low in interaction on the external, peculiar interfacial characteristics such as snow-adhering-preventive properties, water repellency and low friction can be realized, and therefore the coating material can give a coating film excellent in snow-adhering-preventive properties and weathereing resistance.

Abstract: PURPOSE:To improve the emission intensity so as to provide a light emitting material which allows intense emission in a wide visible wavelength range covering blue, green and yellow by adding Ti to perovskite crystal expressed as CaxSr1-xLnTiyAl1-yO4. CONSTITUTION:Laser crystal containing Ti<3+> as a laser activating ion is expressed as CaxSr1-xLnTiyAl1-yO4 (Ln; Y<3+> or Gd<3+>, x; 0.05<=x<=0.5, y; 0.001<=y<=0.05). When the quantity of Ti<3+> is less than 0.001, the emission intensity of the crystal becomes weak, and when it is larger than 0.05, concentration quenching occurs. When the alkali earth metal ion expressed as CaxSr1-x for deforming the crystal field of Ti<3+> is less than 0.05, effects to the symmetrical change of the crystal field becomes small, and when it is larger than 0.5, the optical quality of the crystal deteriorates. Adjustment is made so as to provide such quantity ratios, then the material is mixed, molded and sintered, and the sintered material is melted and solidified in the helium gas atmosphere so as to permit the crystal to contain Ti<3+> by high-frequency induction heating.
