Title: Production of master plate for optical disk
Inventor: OTSUKA YASUHIRO
IPC: G11B7/26
Filed: 1989-03-07
Abstract: PURPOSE:To produce the master plate for optical disk having a large diameter by using a substrate consisting of a glass substrate which is subjected to specular finishing and on which the thin film of alumina is formed to <=1mum thickness as a hard substrate. CONSTITUTION:The substrate which consists of the glass substrate 1 subjected to the specular finishing and on which the thin film 2 of the alumina is formed to <=1mum thickness is used as the hard substrate. Namely, the substrate formed with the thin alumina film 2 on the polished glass substrate 1 is used as the hard substrate, by which working of pregrooves 8 is executed while a diamond tool comes into contact with the thin alumina film 2. Since the alumina is the material chemically stable to diamond as compared with glass, the chemical wear of the diamond tool 7 by the pressing slip between the tool 7 and the hard substrate is decreased and the pregrooves 8 having high accuracy are formed over a long distance. The master plate for optical disk having the large diameter is produced in this way.

Title: Method of and device for recognizing speech
Inventor: AIBEN BURAUNINGU
IPC: G10L15/10
Filed: 1978-05-12
Abstract: An apparatus and method wherein speech or other signals are sampled during a time slice of approximately 1/30 second and spectrum analysis is performed on the samples, producing measures of amplitude in several frequency bands with each frequency band being characterized by a binary digit indicating the presence or absence of significant amplitude. The binary digits are collectively referred to as a sonogram. Sonograms for several time slices are then concatenated, randomized and decoded using an n-tuple technique to produce a pattern corresponding to the current speech signal. This pattern is learned by superimposing it on an existing vocabulary entry and is subsequently recognized if it is sufficiently similar to one vocabulary entry and different from all others.
