  • Patent number: 6488121
    Abstract: In order to provide method of atomizing lubricant at a constant rate in a lubricant atomizer irrespective of the kinds of lubricant and the working conditions, the lubricant atomizer includes a compressed air valve having two branches on its downstream side, which one of two branches is connected to a Venturi mechanism, and the other branch is connected to a constant lubricant supplying pump. Compressed air is fed from the compressed air valve to the Venturi mechanism and to the constant lubricant-supplying pump, thus drawing the air from a sight dome while the compressed air is flowing in the Venturi mechanism. Lubricant is pumped to the sight dome via a constant lubricant supplying conduit, allowing the lubricant to fall in the center of the Venturi mechanism in the form of droplets.

  • Patent number: 5979475
    Abstract: A highly clean fluid treatment system having a small system volume is provided by using a Bernoulli holder to accomplish stable holding of a specimen in a simple configuration. A holder having a specimen hold face formed almost the same as a specimen or having a Bernoulli effect producing region and a region surrounding the Bernoulli region made of a specific combination of materials is used and fluid supply sources are connected to the holder for supplying one or more fluids containing a treatment agent of a specimen. Since a force for inhibiting a position shift occurs on the end face of the specimen 10, stable specimen holding is enabled. The space between the specimen and the holder where treatment is executed is narrow and fluid always flows from the treatment space to the outside. Therefore, the fluid treatment system of a small volume producing high treatment efficiency and minimizing the chances of recontamination of the specimen can be provided.

  • Patent number: 4937454
    Abstract: In a radiation detector having a scintillator and a photodiode in combination, an amorphous silicon diode of a refractive index of 3.5 or below is used for a photodector to have a decreased junction capacitance. This shifts the spectral sensitivity characteristic of the photodetector toward the short wavelength side, thus providing a low-noise, high-sensitivity radiation detector matched well with the emission spectrum of the scintillator.
