Title: Production of carbonic acid diester
Inventor: MIYAKE HIROTO
IPC: B01J31/12
Filed: 1992-10-05
Abstract: PURPOSE:To obtain a carbonic acid diester in high yield and selectivity while keeping high catalytic activity over a long period by using a solid catalyst having low corrosiveness. CONSTITUTION:An alcohol such as methanol is made to react with carbon monoxide and oxygen in the presence of a solid catalyst containing a salt, complex, cation, cation complex, etc., of a metal of the group 1B or 8 of the periodic table inserted between layers of a laminar substance. The laminar substance is a laminar clay substance, laminar graphite substance, etc., having negatively charged layers. A laminar substance containing onium ion, oxide, silane-coupling agent, etc., inserted between the layers may be used as the catalyst. The solid catalyst can be produced by treating a laminar substance with a copper halide or a complex of the copper halide and a nitrogen- containing compound, etc. The deterioration of the catalyst caused by the coagulation of the catalytic components is remarkably suppressed supposedly by the strong interaction between the layer and the inserted component to effect the uniform distribution of the catalytic active points between the layers.

Title: Tape speed controller
Inventor: YAMAGUCHI OSAMU
IPC: G11B15/46
Filed: 1990-10-29
Abstract: PURPOSE:To enable stable control of a tape speed at a high accuracy by correcting a reference frequency to be compared with the sum of an FG frequency of a supply reel and the FG frequency of a winding reel by computing the sum of a ratio between the supply reel FG frequency and a rotation roller FG frequency and that between the winding reel FG frequency and the rotation roller FG frequency. CONSTITUTION:Rotational speed of a reel is controlled so that a frequency of a reference frequency generator 14 is equal to the sum of both FG frequencies of a supply reel 1 and a winding reel 2 while the frequency of the reference frequency generator 14 is corrected by the results calculated from a rotary roller FG output and supply reel and winding reel FG outputs. This allows the direct control of both the FG frequencies of the supply reel 1 and the winding reel 2 and hence, there is no gliding generated between the tape and the reel to achieve a stable control with an substantial rise in a control gain. Besides, the tape speed can be changed simply by changing the frequency of the reference frequency generator 14 thereby enabling the keeping of a set tape speed stably.
