Abstract: Sound data are transmitted to an ADPCM decoder in synchronization with a horizontal synchronizing signal, according to which image data are transmitted.

Abstract: To provide a recording and reproducing apparatus which permits to use tape cassettes different in not only size but also thickness. In order to make the apparatus cope with the tape cassettes different in size and thickness, there is provided a positioning guide mechanism including a pair of positioning guide members so that a small cassette can be guided at both the side faces on a cassette supporting surface of the cassette holder so as to be depressed and projected by a biasing means, and a pair of side plates at its both sides of a cassette holder so that a large cassette can be guided at its both side faces. If a user is not highly skilled in operating such recording and reproducing apparatus which permits to use tape cassettes different in size and thickness, the apparatus will suffer from risk that the cassettes are erroneously inserted or the user carries out malicious operation.

Abstract: A computer system having a control unit, a storage, a first register for storing a scale value transmitted from the storage, a second register for storing ADPCM sound data transmitted from the storage, and an ADPCM decoder for reproducing sound in accordance with calculating the ADPCM sound data and the scale value and holding the ADPCM sound data and the scale value therein until next ADPCM sound data are transmitted thereto normally. The ADPCM decoder reproduces the sound from the middle of the ADPCM sound data by using the ADPCM sound data and scale value held therein.

Abstract: A computer system having a storage, calculating portion, an ADPCM decoder, and recovery portion. The recovery portion calculates a recovery value based on control data and an initial scale value and replaces a reproduced value with the recovery value if a reproducing operation stops halfway through a sound data. Thus, the ADPCM decoder reproduces sound from the middle of the sound data.

Abstract: Sound data are transmitted to an ADPCM decoder in synchronization with a horizontal synchronizing signal, according to which image data are transmitted.

Abstract: A continuous mixer in which the rotors used to mix the material are composed of a rotor shaft, and a plurality of rotor segments fitted onto said rotor shaft. The plurality of rotor segments can be removed from the shaft and replaced by rotor segments of differing specifications to produce a rotor of a different shape and specifications in accordance with any change in the kind of mixing conditions required.

Abstract: A method of controlling slag coating in a steel converter in which slag is left in the converter after tapping, and a slag solidifying agent is added to the slag to form a coated slag which is used to coat the bottom and/or side wall surface of the converter. The method is performed bya) examining the composition of the slag at the tapping time;b) determining, based on the examined slag and through an equilibrium calculation using thermodynamic data, the amount of solidifying agent per unit weight of the slag necessary for maintaining the liquid volume fraction of the coated slag to a value not greater than about 40% at the planned tapping temperature of the next charge of steel;c) determining the amount of charge of the solidifying agent based on the calculated required amount of the solidifying agent and the amount of the slag remaining in the converter; andd) adding the calculated charge of the solidifying agent to the slag after tapping, to form a coated slag.

Abstract: A sound processing apparatus has a volume control circuit for controlling sound volume and a register storing plural values specifying attenuation levels. The register values are determined to linearly correspond to the rate of change of the attenuation level.

Abstract: The present invention is directed to a method for the preparation of p,p'-biphenol by simplified processes achieved by batch or continuous operations which comprises using phenol and isobutylene as starting materials, allowing phenol to react with isobutylene in the presence of aluminum phenoxide, oxidizing the resulting reaction liquid in the presence of an alkaline catalyst, and debutylating the reaction liquid in the presence of a debutylation catalyst.

Abstract: An exposure device includes a light source, means for transmitting radiation from the light source to the surface of a photosensitive film, and photosensitive information outputting means for measuring and outputting information which represents the state of exposure of the surface of the photosensitive film. A suitable exposure can be determined by detecting changes in the properties of the resist. In consequence, exposure can be adjusted to fit the exposed state of the photosensitive film which would be impossible in the prior art. Further, variations that occur in exposure can be decreased, and yield can be improved.
