摘要:
A device for sealing the shaft of a turbo machine in which there are disposed a shaft sealing side plate attached to a casing, an atmospheric side floating ring and an in-machine side floating ring arranged in a seal case and associated with the shaft with the interposition of a small space, the atmospheric side floating ring having an atmospheric side end surface in contact with the shaft sealing side plate, the in-machine side floating ring having an in-machine side end surface in contact with the seal case; the device being characterized in that a flexible ring which is deformable in compliance with the deformation of the atmospheric side floating ring during driving is interposed between the atmospheric side floating ring and the shaft sealing side plate, whereby an excessive load is not applied between each white metal of both the floating rings and a seal sleeve, hardening and scalling loss of the white metal are prevented, and the reliability of sealing in the turbo machine is improved.

A disclosed transparent body detection system includes an image acquisition unit acquiring a vertical polarization image and a horizontal polarization image by acquiring an image of a first region, the image including a transparent body having characteristics in which a polarization direction of transmission light changes; a placing table on which the transparent body is to be placed; a polarization filter disposed opposite to the image acquisition unit across the placing table and at a position including a second region, an image of the second region including at least the transparent body in the first region and being acquired; and an image processing apparatus detecting the transparent body based on distribution of vertical/lateral polarization degree of a vertical/lateral polarization degree image based on the vertical polarization image and the horizontal polarization image.
摘要:
A hermetic compressor has a hermetic container storing oil, and a compressing element accommodated in the hermetic container and compressing a refrigerant gas. The compressing element has a compression chamber, a cylinder forming the compression chamber, a piston inserted into the cylinder for reciprocation, and a suction muffler whose one end communicates with the compression chamber. The suction muffler has a sound deadening space, a gas flow forming part forming a gas flow flowing in a constant direction in the sound deadening space, and an oil discharge opening provided in a downstream side of the gas flow in a lower part of the sound deadening space. By this construction, there is realized a hermetic compressor in which the oil does not readily remain in the suction muffler, whose noise is lower, and whose performance is stabilized.

Liquid packs 34 provided with liquid leading members 42 are stored in a container case 31 that is constituted by fitting a case main body portion 32 and a lid case 33 in fitting portions 27 and 28, support portions 13, which positions the liquid leading members 42 so as to be opposed to liquid introducing members 71 attached to a cartridge inserting portion 13, are provided on a front surface 32a of the container case 31, the fitting portions 27 and 28 are arranged in a state in which the fitting portions 27 and 28 traverses the support portions 43, and space portions 29 and 30 having a gap larger than a gap formed in the fitting portions 27 and 28 are formed near the support portions 43 in the fitting portions 27 and 28. In this way, liquid flowing through the fitting portions 27 and 28 due to the capillarity is retained by the space portions 29 and 30 and never flows to the fitting portions 27 and 28 further extending from the space portions 29 and 30.
摘要:
The infrared absorption filter of the present invention has a transmittance of not higher than 30% in the near-infrared region in the wavelength range of 800 to 1100 nm; a difference of 10% or less between a maximum value and a minimum value of transmittance in the visible light region in the wavelength range of 450 to 650 nm; and a transmittance of not lower than 50% at a wavelength of 550 nm, the filter being so excellent in environmental stability that after being left to stand in the air atmosphere at a temperature of 60° C. and a humidity of 95% for 1000 hours, the filter can maintain said spectral property in said range. Consequently, when used for a plasma display or the like, the filter can absorb the unwanted infrared rays radiated from the display, resulting in preventing erroneous operation of a remote control using infrared radiation even in such a high-temperature and high-humidity environment. The filter is gray in color so that when placed in front of a display, the color originated in the display can be seen without discoloration.
