Abstract: PURPOSE: To prevent the decrease in permeating luminous flux in long-term opeation by deciding the time of cleaning of adsorbing materials in accordance with the time for the decrese in permeating luminous flux.  
     CONSTITUTION: Liquid Ld to be treated is once stored in a raw water tank 1, and is fed via valves 3, 4 to a module 5 by a high pressure pump 2. The permeated liquid is taken out through a detector 6 for amt. of permeated liquid, and the concd. liquid is taken out through valves 7, 8. The detector 6 outputs a detection signal to a controller 9 when the amt. attains the 80% liquid permeating amt. at the start of operation. On receiving this signal, the controller 9 stops the pump 2, and at the same time, changes over the valves 3, 8. The valve 3 is changed over from the pump 2 side to cleaning liquid side, and the valve 8 to the raw water tank 1 side. Further, the valve 11 is changed over to an industrial water tank 12 side, to force out the liquid to be treated from the inside of the module 5. Thence, the valve 11 is changed over to a cleaning liquid tank 13 side to clean the inside of the module 5.

Abstract: PURPOSE:To obtain a compact and efficient condensing device which has no influence upon a finder image, by providing a condensing element having a diffraction grating structure between the exit face of a pentagonal prism and an eyepiece lens in a single-lens reflex camera. CONSTITUTION:A saw tooth-shaped diffraction grating structure 5 is formed on a plane of a condensing element 1 which faces the eyepiece lens, and each face constituting the diffraction grating is a reflective mirror. When a luminous flux 6 is incident to the reflective diffraction grating, it is reflected strongly in the direction of a specific angle theta if the angle and the pitch of respective reflective faces satisfy braced conditions. If the reflection angle is larger of the critical angle of total reflection with respect to the refractive index of a medium constituting the condensing element 1, the reflected luminous flux is total-reflected by another plane 9 and is emitted finally from an end face 7 of the condensing element 1. This reflective diffraction grating structure is provided only in a region where the light should be condensed so that ridge lines 8 of the diffraction grating form the shape of a fan with a point O as the center, thereby obtaining the condensing element having an efficient condensing function.

IPC: B32B38/00
Filed: 1997-05-27
Abstract: PROBLEM TO BE SOLVED: To unify and stabilize the quality of a laminated plate by performing a cooling of a high efficiency after a heat-press-forming, and drastically shorten a lead time by a method wherein intermediate plates are projected from a metal foil which is constituted into a zig-zag folded state, and cold air is jetted to the projected intermediate plates. SOLUTION: Intermediate plates 1 project from a metal foil 2 which is constituted into a zig-zag folded state in such a manner that the end parts of the intermediate plates 1 respectively arranged in the vertical direction may be alternately located. Therefore, when the positions of a straight line A connecting the end parts of the projected intermediate plates 1 and a straight line B connecting the end parts of retracted intermediate plates 1 are compared, a gap 7 of which the interval is 1-2 cm is formed. A flat plate 4 is arranged along the side surfaces of the metal foil 2 while having a fixed interval from the straight line A connecting the end parts of the projected intermediate plates 1.  The flat plate 4 suppresses the stream of cold air in such a manner that the stream of the cold air may flow along the intermediate plates 1 when the cold air is jetted to the gap 7 which is formed of the end parts of the intermediate plates 1.
