摘要:
A reproducing apparatus is arranged to reproduce from a recording medium a data string including image data and motion data indicative of motion of an image related to the image data, and to control the speed of reproduction of the image data according to the motion data included in the data string reproduced.
摘要:
An optically active amino acid derivative is produced by N-protecting an optically active 3-haloalanine derivative followed by cyclization, or cyclizing this derivative followed by N-protection to thereby give an optically active N-protected-aziridine-2-carboxylic acid derivative which is protected by a benzenesulfonyl group substituted by nitro at the 2- and/or 4-positions and then treating this product with an organic metal reagent, or by N-protecting an optically active 3-haloalanine derivative to thereby give N-protected-aziridine-2-carboxylic acid which is protected by a benzenesulfonyl group substituted by nitro at the 2- and/or 4-positions and then treating this product with an organic metal reagent. According to this process, natural and unnatural optically active amino acids can be produced from inexpensive materials by using simple procedures.
摘要:
This document describes a novel and practically excellent process for the preparation of optically active compounds, such as optically active alcohols or amines which are useful for various applications, for example, as synthetic intermediates of pharmaceuticals, liquid crystal materials, and reagents for optical resolution, wherein a hydrogen transfer type asymmetric reduction is carried out in the presence of both a transition metal complex and an optically active nitrogen compound or a transition metal complex having an optically active nitrogen compounds as an asymmetric ligand, and a hydrogen-donating organic or inorganic compound.
摘要:
The present invention provides an image signal reproducing apparatus, in which code errors are concealed by using only pixel data corresponding to parts of the pixels of respective two or more adjacent blocks both of which are adjacent to a subject block to be concealed in the same frame, to conceal the code errors without disturbing the image even if the image is rapidly moving and all of pixels included in the block are not available.

A frictional engaging clutch for an automatic vehicle transmission which discriminates judder which has occurred on the vehicle and controls to decrease the same. A clutch slip ratio is calculated, the calculated ratio is then converted into an ac waveform which is filtered by filters similar to a judder filter and a disturbance filter to extract frequency components of an appropriate range, and the number of times (NTEX) at which the filtered waveform peaks exceeds threshold values (appropriately set) is counted, and based on the counts, the judder is discriminated or determined. The configuration is simple and makes it possible to discriminate judder in an automatic vehicle transmission.
摘要:
An information signal reproducing apparatus capable of correcting digital an information signal utilizing correction data, is formed from a reference signal contained in an information signal reproduced from a recording medium, in which the correction of the digital information signal is conducted behind a digital signal processor for processing the digital information signal corresponding to the reproduced information signal, so that the number of bits handled by the digital signal processor is minimized and the circuit magnitude of the digital signal processor is reduced.
摘要:
Noise contained in a reproducing image signal is suppressed by performing a filtering operation on an image signal obtained by decoding data that has been coded with a unit of a block consisting of m.times.n pixels. A filter circuit having a plurality of filter characteristics suppresses noise, and a characteristics selection circuit switches the filter characteristics of the filter circuit by use of a quantizing parameter employed for coding the image signal.
