Title: Goniometer in fluorescent x-ray analyzer
Inventor: KATO TOSHIAKI
IPC: G01N23/223
Filed: 1990-07-24
Abstract: PURPOSE:To dispense with the use of a worm gear and a worm by providing a motor directly rotating an X-ray detector and a speed reducing means which sets the rotary ratio to 1/2. CONSTITUTION:When a rotary body 17 is rotated by a motor control system not shown in a drawing, an X-ray detector 6 is integrally rotated along with the rotary body through an arm 23 and, at the same time, a rotary shaft 9 is rotated in the same direction through a speed reducing mechanism 24. At this time, since the speed reducing ratio of the speed reducing mechanism 24 is set to 1/2, a spectral crystal 4 and an X-ray detector 6 are rotated in the ratio of 1 : 2 with the rotation of the rotary body 17 and, therefore, X-rays spectrally diffracted by the spectral crystal 4 can be detected while the Bragg diffraction condition is satisfied. An electromagnetic brake for locking the movement of the spectral crystal and the X-ray detector when the supply of a current to a motor not shown in the drawing is stopped is provided. Since the X-ray detector is directly rotated without using a worm gear and a worm, a lubricant becomes unnecessary and the maintenance of replenishment or covering is unnecessary and handling becomes extremely easy.

Title: Gas return piping for low temperature liquefied gas base
Inventor: TAKAKURA MINORU
IPC: F17C13/00
Filed: 1985-09-06
Abstract: PURPOSE:To prevent the temperature dropping of a return pipe caused by gas convection and heat conductive through piping by constituting a gas return pipe so that gas may enter the connected part of the gas return pipe to piping on a reservoir side at its upper part. CONSTITUTION:The supplying pipe 5 of a boil-off gas (BOG) compressor 4 is branched to connect with a return pipe 6 whose other end is connected to a BOG pipe 7. The connected part 8 of the return pipe 6 to the BOG pipe 7 on a reservoir side is connected to the pipe 7 on its upper side, and since the low temperature BOG in the pipe 7 is lower in temperature and heavier in specific weight than the BOG in the return pipe 6, gas convection does not cause the lower temperature BOG to flow into the return pipe 6. Thus the temperature dropping of the return pipe can be prevented.
