Title: Production of activated carbon
Inventor: YAMAGUCHI TOKUJI
IPC: C01B32/336
Filed: 1989-02-21
Abstract: PURPOSE:To easily and inexpensively produce good quality activated carbon from caking coal by adding rice bran to pulverized coal, carbonizing the mixture, crushing and grading the carbonized material and then activating the graded material. CONSTITUTION:Rice bran is added by 1-40wt.% to pulverized coal having preferably <=74mum grain size. The mixture is charged into a carbonization furnace, heated to about 700 deg.C and carbonized. When the caking property is low, the mixture is press-formed, and the granulated coal is heated to about 600 deg.C in the carbonization furnace and carbonized. The carbonization product is preferably graded to 5.0-0.3mm grain size in accordance with the grain size of the desired activated carbon. When the granulated coal is oxidized and carbonized, the granulated coal is charged into a reaction vessel held at 100-310 deg.C and carbonized in the gaseous mixture contg. 1-22vol.% O2. The carbonization product is then activated by the conventional method to obtain activated carbon. The activated carbon is used in water treatment and as a solvent adsorbent and a gasoline adsorbent.

Filed: 1998-02-23
Abstract: PROBLEM TO BE SOLVED: To facilitate replacement or maintenance and to measure flow rate easily in a short time by arranging a piping in a potential core formed in the vicinity of a pressure fluid ejection port in order to measure the flow rate thereby eliminating the need for fixing a measuring unit to the way of a piping. SOLUTION: When compressed air is ejected from a nozzle 64, a substantially conical potential core 66 being regarded to have a substaittally uniform current velocity of compressed air is formed in the vicinity of opening of the nozzle 64. Piping 38 of a measuring unit 32 is arranged in the potential core 66, compressed air is introduced from the piping 38 through a tube 34 into a semiconductor sensor 42 and the pressure thereof is measured. A microcomputer 46 determines the flow rate of compressed air based on the effective cross-sectional area of the nozzle 64 (at a position where the compressed air flow is constricted most), temperature of the compressed air, and difference between the measured pressure and the atmospheric pressure, and the atmospheric pressure. A portable flow rate measuring unit of simplified structure is thereby obtained and measurement efficiency is enhanced.

Abstract: PURPOSE: To enable the sheet ejected from a housing box to be easily detached from an ejecting plate without damaging the same by providing a suitable number of leaf springs to the nonlevel-differing part of the ejecting plate in a sheet extracting device.  
     CONSTITUTION: A suitable number of through-holes 21 are pierced in the nonlevel- change 5b part of an ejecting plate 5 on which a sheet 1 is placed. Leaf springs 22 curved to the nonlevel difference 5b side of the ejecting plate 5 are seated in these through-holes 21, and are fastened to the plate 5 by means of screws 23. The intensity of these leaf springs 22 are set at such strength at which they detach from the plate 5 when the sheet 1 is pushed from below in the state ejecting from the housing box. Hence, when the plate 5 positions in the housing box, they will not hinder the close contact of the sheet 1 with the plate 5. With this construction, the ejected sheet 1 is positively detached from the plate 5, hence the overlapping and failure of the sheet 1 are prevented.

This optical fiber plate 4 is formed like one piece of plate by bundling many optical fibers 5 of a thin diameter and cutting them so as to become prescribed thickness by the surface vertical to the optical transmission direction of these optical fibers 5. When incident light is made incident on the optical fiber plate, since as for this optical fiber plate, that which has a small numerical aperture is used, only a light beam whose incident angle is small passes through, and a light beam exceeding said angle does not pass through. Therefore, only roughly parallel rays are selected and pass through. In such a way, a light beam of only specific wavelength based on a characteristic of the optical interference filter is selected and outputted.
