IPC: H01L21/677
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To prevent the scattering of dust so as to prevent deterioration in the degree of cleanness in a manufacturing facility shop by discharging air introduced to the cassette housing transferring chamber inside from the lower side of a cassette conveying vehicle via an air flow damping filter arranged on the side wall front face inside the housing transferring chamber and an air passage. SOLUTION: Sucked air from an air suction port 31 formed on a rear face wall 3R in a cassette conveying vehicle 3 is introduced to the inside of a cassette housing transferring chamber 30 from an air passage 35 via a HEPA(High Efficiency Particulate Air) filter 32a and a fan 32b arranged on a side wall 38. Then, the sucked air is discharged from the lower side of the cassette conveying vehicle 3 via an air flow damping filter 6, which is arranged on the front face of a side wall 37, and an air passage 33. In this way, no turbulence of air flow due to a collision of the introduced air against the side wall 37 in the cassette housing transferring chamber 30 is caused and the scattering of dust can be prevented, so that dust is prevented from infiltrating from a doorway 39 of a cassette and an opening of a partition wall into a manufacturing facility shop.

Filed: 1980-07-21
Abstract: PURPOSE:To obtain an inexpensive broad-band branching filter which separates light with a less wavelength difference excellently by using at least one interference filter and Littrow mounting type diffraction gratings or prisms in combination. CONSTITUTION:For an optical fiber array FA and an optical lens system L, one interference filter F and two diffraction gratings G1 and G2 are arranged by Littrow mounting. Wave-multiplex light (lambda1-lambda5) traveling in one main optical fiber 0 in the optical fiber array FA is made incident to the interference filter F, where it is separated into groups I and II of reflected light (lambda1-lambda3) and transmitted light (lambda4 and lambda5). The groups I and II of light are diffracted by diffraction gratings G1 and G2; and the diffracted components are passed through the interference filter F and the  lens system L to enter components, having wavlengths lambda1-lambda5, into optical fibers  1-5 respectively. Thus, light components having a less wavelength difference are  distributed excellently by the inexpensive broad-band optical branching filter.

Abstract: PROBLEM TO BE SOLVED: To improve efficiency by dividing light from a light source means into plural optical paths through an optical path dividing means provided between the light source means and a color separating means and composed of plural reflection mirrors. SOLUTION: White light emitted from a light source 106 of a light source part 101 is emitted from a second lens array 110 and made incident on an optical path dividing system 102. The light made incident on the system 102 is divided into two optical paths by dividing mirrors 113 and 114 in rectangular shape. The light reflected on the dividing mirror 113 is made incident through a return mirror 115 to a blue reflection dichroic mirror 116. The light in blue is transmitted through this mirror and light in red and blue is reflected. In the reflected light, the light of a green component is reflected on a green reflection dichroic mirror 117 and light in red is reflected on a reflection mirror 118.  Thus, the light in each light transmitted through or reflected on the mirror of the optical path dividing system, the main beams of light in each color are converged to the center of an effective part on a liquid crystal panel 111 by a Fresnel(R) condenser lens 123.
