Title: Method for activating dimethyl ether synthesis catalyst by reduction
Inventor: OGAWA TAKASHI
IPC: C07C43/06
Filed: 1996-12-27
Abstract: PROBLEM TO BE SOLVED: To stably activate a catalyst by reduction at a low cost after dimethyl ether is synthesized by bringing synthesis gas contg. CO and H2 into reaction with the catalyst by using part of unreacted gas after the reaction as a reducing agent for the catalyst. SOLUTION: Most of recyclable gas 7' separated from gas 5' produced by reaction in an unreacted gas separator S2 is fed into a gas mixer M1 through lines 7, 7a, mixed with makeup gas 1' and fed into a DME synthesis reactor R1. The remainder of the gas 7' is fed as catalyst reducing gas into the reactor R1 through a reducing gas line 13. Recyclable gas 7' from the separator S2 is allowed to flow into a storage line 11 by means of a gas changeover device C1 and is stored in a storage tank T1. Recyclable CO2 separated in a CO2 separator S3 is stored in a storage tank T2, fed into a gas mixer M2 through a flow rate control valve f1 and properly mixed with recyclable gas 7a'.

Title: Image reader
Inventor: KUWAMOTO SHIGEKI
IPC: H04N1/40
Filed: 1995-12-29
Abstract: PROBLEM TO BE SOLVED: To provide an image reader from which an optimum image is simply obtained. SOLUTION: In the execution of reading of image data for plural number of times (S1), the number of times of reading is set (S3). After the selection (S4) as to whether or not a step change is caused, a parameter pattern is set (S8). Reading of image data is executed repetitively sequentially based on the set parameter (S9, S10, S12). Furthermore, the parameter is set manually, automatically or reading setting for only once is attained. Thus, in the reading of a same original for plural times, the user reduces the time required to set the parameter by reading data while changing the parameter automatically. Furthermore, the parameter changes of each read image is compared easily and visually.
