Title: Centrifugal separator
Inventor: TANAKA KENICHI
IPC: B04B3/00
Filed: 1987-03-24
Abstract: PURPOSE:To shorten the time before reaching an equilibrium state from the initial start state of rotation, by mounting the shaft part coaxial to the center of rotation of a bucket to a support table 2 and supporting the lower end part of said shaft part in a spherical kinematic pair state by a fixing part. CONSTITUTION:A bucket 1 is supported by a support table 1 while the support table 2 is supported between a fixing part and the bucket 1 in a spherical kinematic pair state by a shaft part 22. When the bucket 1 is rotated, the bucket 1 performs precession at the initial stage of rotation but, since the center of the precession becomes the spherical kinematic pair part of the lower end part of the shaft part 22 and the fixing part, it is fixed to one point. Therefore, when the rotation of the bucket 1 gets fast, the rotary axial line thereof is transferred so as to coincide with the vertical line passing the fixed point as it is. By this method, the required time before the bucket 1 gets to an equilibrium state can be shortened.

Filed: 1984-04-09
Abstract: PURPOSE:To attain low power consumption by correcting a change of a control voltage to a VCO at PLL loop cut-off and executing intermittently the PLL operation in a PLL frequency synthesizer. CONSTITUTION:When a loop cut-off switch 311 is turned off by a control signal from a loop cut-off controller 314, the control voltage from a loop filter 310 is fed to an operational amplifier 312. The control voltage is changed when the switch 311 is turned off. Then an output of a ramp signal generator 313 is fed to the operational amplifier so as to correct the change in the control voltage and the result is fed as the control voltage to the VCO301. On the other hand, when the switch 311 is turned off, the power supply to a prescaler 304, a TCXO 308 and a PLL LSI 315 is stopped. The PLL operation is executed intermittently by the interruption of the power supply. Thus, low power consumption is attained.

Abstract: PURPOSE:To enhance space efficiency and to jointly use two or more kinds of luminaires by suitably selecting an indirect light projecting means and a direct illuminating means, and switching them by a switching means. CONSTITUTION:An indirect light projecting means and a direct illuminating means are prepared. When it is used as indirect lighting, a slide plate 4 is slid backward, so that a reflector 3 is directed to a lamp bulb 1. When an electric current is sent to the lamp bulb 1 in this state, the light reflected by the reflector 3 is reflected again at an oblique side part of a light-guiding-plate 5 to be diffused upward. Then the light is projected to a head lining 7 and becomes indirect light coming from the upper part of an installation plate 6. Next, when it is used as a spot lamp, the slide plate 4 is slid forward, so that a lens 2 is directed to the lamp bulb 1. Therefore, the light is concentrated by the lens 2, thereby giving a spot lamp state. At the same time, the light on the light-guiding-plate 5 side of the lamp bulb 1 is guided upward by the light-guiding-plate 5, so that it is projected to the head lining 7 and becomes indirect light coming from the upper part of the installation plate 6.
