摘要:
A hydraulic control apparatus for a single action cylinder includes a switch valve for supplying fluid to and draining fluid from the cylinder, a cylinder side passage connected to the cylinder, a switch valve side passage connected to the switch valve, and a valve body accommodation chamber. The valve body accommodation chamber linearly extends between the cylinder side passage and the switch valve side passage. An on-off valve is located in a vicinity of a first end of the valve body accommodation chamber. The on-off valve defines a first back pressure chamber. A flow control valve is located in a vicinity of a second end that is opposite to the first end. The flow control valve defines a second back pressure chamber. The on-off valve and the flow control valve are separated from each other by a partitioning member.

摘要:
A recording medium has a first recording area on which recording information is recorded as a set of recording units, and a second recording area on which control information for controlling the recording information to be recorded on the first recording area is recorded. Identifying information for identifying a management condition of the recording information recorded on the first recording area is also recorded on the second recording area at every recording unit.
摘要:
A recording apparatus capable of recording an audio signal on a recording medium without introducing a deterioration in sound quality. When a digital audio signal input to a digital audio input terminal has a predetermined signal form, the digital audio signal is recorded on the recording medium instead of an analog audio signal input to an analog audio input terminal.

Disclosed is an FM stereo demodulator in which components of the demodulated signal corresponding to odd harmonics of the subcarrier signal are eliminated.In order to prevent the production of odd harmonics, the multiplication between positive and negative sinusoidal subcarrier signals is performed with a stereo pilot signal and positive and negative pulse train signals produced by pulse detection of an FM signal.The multiplication signals are further added with each other to directly reproduce left and right stereophonic signals.
摘要:
An FM stereo demodulator having improved separation and distortion characteristics comprising a high-frequency pulse signal which is modulated by a sinusoidal subcarrier signal produced in accordance with a stereo pilot signal. The high-frequency pulse signal is multiplied with a composite signal at a multiplier so as to reproduce left and right signals without frequency components of noise. Constructed accordingly, the invention advantageously obviates the use of a low-pass filter which injects delay characteristics and reduces gain of the composite signal from an FM demodulator.
摘要:
An information editing apparatus for editing a reproduction manner of record information which is recorded on an information storage medium and includes at least one picture information, includes: a selecting unit for selecting a partial record information from the record information, the partial record information being part of the record information and including at least one picture information; a designating unit for designating a reproduction timing of the selected partial record information; an extracting unit for extracting the picture information included in the partial record information as a representative picture information indicative of the partial record information; and a recording unit for recording one of the extracted representative picture information and a designation information indicative of a recorded position on the information storage medium of the representative picture information and the designated reproduction timing on the information storage medium as a reproduction control information separately from the record information.
摘要:
A recording apparatus comprises a recording device, a changing device, a storage device and a control device. The recording device records recording data on a recording medium. The changing device receives a plurality of recording media supplied from an outside, selects one of the plurality of recording media as received and replaces the first recording medium loaded in the recording device with the second recording medium as selected. The storage device stores, during replacement of the first recording medium, the recording data recorded thereon. The control device controls the recording device and the changing device, monitors a remaining recording capacity or recording time of the first recording medium during recording, causes the first recording medium to be replaced based on monitoring results, and reads, after completion of the replacement of the first recording medium, the recording data of the first recording medium from the storage device and records same on the second recording medium.
摘要:
A digital data recording/reproducing apparatus which divides each of information data pieces into a plurality of cells, further divides each of the cells into a series of a plurality of units, and records the units. The digital data recording/reproducing apparatus has means for recording a required time for reproduction until the head position of a unit is reached, with reference to the head position of an information data cell to which a cell belongs, as a unit start time, in addition to each of the units, and means for recording a cell start time (Ts) equal to a required time for reproduction until the head position of each of the cells is reached, and a required time for reproduction (Ps) of each of the cells in a management data region.
