IPC: C01B3/32
Filed: 1999-11-30
Abstract: PROBLEM TO BE SOLVED: To promptly cool a catalyst layer while achieving prevention of a thermal runaway and removal of a residual fuel when shutting off a methanol reforming device. SOLUTION: An introduction of air is initially stopped to progress a steam reforming reaction which is an endothermic reaction while suppressing a partial oxidation reaction which is an exothermic reaction when shutting off a reforming container 23.

Title: Method and apparatus for shift of analysis-coded time axis by universal synthesis
Inventor: UIREMU BASUCHIAN KUREIJIYUN
IPC: G10L19/12
Filed: 1993-12-14
Abstract: PURPOSE: To provide a speech encoding method which employs analytic technique by general synthesis. CONSTITUTION: Part of a source signal containing maximum energy is discriminated. Segments of the source signal which contain the maximum energy are selected on the basis of time-base shifts. These segments are named 'test source signals'. Respective test source signals are compared with a composite signal, obtained from an adaptive code book, to evaluate degree of similarity (for example, mutual correlation) among these signals. A test source signal used for encoding is determined on the basis of the degree of similarity evaluated. A signal giving the encoded representation of the source signal is generated on the basis of the determined test source signal. This signal giving the encoded representation of the test source signal can be supplied by an analytic encoder which employs a synthesis similar to a code excitation type linear predictive encoder.
