Title: Liquid crystal sheet thermometer
Inventor: ENDO HIROYUKI
IPC: G01K7/00
Filed: 1989-08-24
Abstract: PURPOSE:To find accurate temperature with good response by applying a rectangular or triangular voltage, measuring the response time when a dipole is inverted in ferroelectric phase from the peak of a polarization inverting current, and using data on the temperature and response time. CONSTITUTION:When a control means 41 commands a voltage applying means 20 to apply a voltage to a specific position of a sheet type temperature sensing means 10, an applying means 20 applies the rectangular wave, etc., to an electrode line corresponding to the specific position between electrodes 14 and 15 according to the command. When the rectangular wave voltage, etc., is applied from the applying means 20, the dipole of liquid crystal molecules of the liquid crystal cell at the part applied with the voltage is inverted as the polarity of the voltage is varied so that the polarization inverting current flows to the liquid crystal cell. A current variation measuring means 30 measures the current polarization inverting current and sends the result to the calculation part 42 of a processing part 40. The calculation part 42 finds the response speed tm or tw of the liquid crystal cell from the current variation sent from a varying means 30 and finds the temperature corresponding to the response speed tm or tw from the response-speed/temperature characteristic data of the ferroelectric high polymer liquid crystal which is stored previously in a data storage means 43.

Abstract: PROBLEM TO BE SOLVED: To improve lubricity, slidability and rolling performance of a sliding surface by forming a porous layer on the side of a sliding surface of a sliding bearing, impregnating the porous layer with extreme-pressure additive, and thereby forming a molecular adsorption layer or a reaction lubrication film. SOLUTION: A sliding bearing 41 which journals a planetary gear to a pin has a porous layer 43 made of sintered material on its inner peripheral side. The porous layer 43 is impregnated with extreme-pressure additive 44. Sliding is performed by driving a deceleration gear mechanism in the state that an outer periphery of the pin is in direct contact with a sliding surface of the sliding bearing 41. The extreme-pressure additive 44 contained in the porous layer 43 is bled, and stuck to the surface of the pin. A molecular adsorption film or a reaction lubrication film is formed between the pin and the sliding surface of the sliding bearing 41 by the extreme-pressure additive 44 stuck to the surface of the pin. Rolling performance or slidability of the sliding surface is improved, and abrasion or galling is reduced at the sliding surface of the bearing 41 and the outer periphery of the pin.

Abstract: PURPOSE:To obtain a high-purity silicon with minimal boron concentration, by melting a boron-contg. crude silicon followed by adding at least one kind of element selected from Zr, Ti and V to the resulting melt and cooling while stirring to effect solidification. CONSTITUTION:At least one kind of element selected from Zr, Ti and V is added to a boron-contg. molten crude silicon in such quantities as to be ca. 10-1,000 times the stoichiometrically necessary amount for forming the respective borides from the boron present in said molten silicon, and agitated. Thence, said molten silicon is solidified at a rate of <=8mm/min in an inert gas atmosphere and left at rest to affect precipitation, alternatively, the boride formed by stirring said molten silicon is solidified by putting it away from the solidification interface; thus leading to the minimal boron concentration in the silicon mass to the extent of solidification of 70% of the whole molten silicon. Since excess of Zr, Ti and V are very small in the respective equilibrium segregation coefficients, they will be eliminated on the principle of segregated solidification, thus being rarely incorporated into the resultant solid phase.

CONSTITUTION:A dust pan 23 has a width, i.e., the length between the fore and aft brims, equal or nearly equal to the width of the bottom of a heating compartment, 12, i.e., the length between the front edge 17b of a rear panel 17 and the inner face 19c of a door 19. The rear panel 17 is made of an elastic material so that the front edge 17b of the rear panel 17 is able to move back and forth inside the heating compartment 12.

Filed: 1986-09-16
Abstract: PURPOSE:To prevent generation of vibration due to inertia force of a lens holder by giving acceleration in the same direction as the acceleration generated in the moving base at the time of high speed accessing operation. CONSTITUTION:When force (fc) is applied to a moving base 4 and acceleration is generated in the moving base 4, force (fa) that generates acceleration of the same value and in the same direction is applied to a lens holder 6. As the mass of the moving base 4 is (mc) and the mass of the lens holder 6 is (ma), to generate the same acceleration alpha in the moving base 4 and lens holder 6, fc=mcXalpha, fa=maXalpha are satisfied. Accordingly, force to be given to the lens holder 6 is fa=(ma/mc)fc. That is, when force (fa) is applied to the lens holder 6 in case the moving base 4 makes high speed accessing operation, the lens holder 6 and moving base 4 have the same acceleration alpha, and vibration of the lens holder 6 caused by inertia force can be prevented.
