Abstract: In a digital recorder, a signal process can be performed on digital audio data track by track or event by event in a recording mode or in a reproducing mode. In the recording/reproducing mode, transfer of digital audio data between a hard disk and respective audio input/output devices is executed in real time under control of a DMA controller and a HD controller. A DSP provided between the DMA controller and the HD controller performs the signal process such as a filtering process on digital audio data (block data) of several samplings in a lump, which are transferred (DMA transfer) in a lump between the buffer and the hard disk.

Abstract: A thermomechanical analyzer including a vertical probe secured to a probe holding bar. The probe and the probe holding bar are coupled to a force generator for supplying a force in the vertical direction, a differential transformer for detecting the degree of movement in the vertical direction, and two supports each composed of a pair of wires and a coil spring in the horizontal direction. The force generator is located between the two supports. Thus, the movement of the probe holding bar in a radial direction is controlled. The size of the instrument becomes compact. As the movement of the probe holding bar in a radial direction is controlled to be very small, the moving range of the probe becomes broader and a large sample deformation can be measured with precision.

Abstract: There is a digital recorder which is capable of editing audio data read out from an audio-data storing device such as a hard disk and a magneto-optical disk, with high accuracy of a sampling frequency. When audio data stored on an audio-data storing disk is divided into a plurality of separate event data for reproduction, the event data are defined by sampling-data units, which units are used for defining digital audio data. When the audio data is transferred to a temporarily storing buffer, unnecessary portions of the event data near the leading portion and the ending portion of the event data are transferred as dummy data for fine adjustment.

Abstract: Recorded data is read by an image sensor from a recording medium on which the data is two-dimensionally recorded in a mesh pattern, and the read data is stored in an image RAM. The stored data is subjected to data decoding and error correction to reproduce target data. A scanning reference pattern of a mesh pattern recorded on the recording medium serves as a guide when the stored recorded data read by the image sensor is reproduced by scanning in the image RAM. A reproduction apparatus has a capability of coping with a partial destruction of the scanning reference pattern. Error checking codes are added to the recording medium in addition to the target data. These items of data are recorded as an encoded image after being subjected to scrambling processing and randomization processing. The reproduction apparatus can easily cope with an error when the encoded image is reproduced.

Abstract: An apparatus for dynamic measurement of viscoelasticity of a sample through oscillating displacement thereof. A detector detects oscillating displacement of a sample and produces a corresponding displacement signal having top and bottom peaks and containing an amplitude component due to the oscillating displacement and an offset component due to long-term deformation of the sample. A driver shifts the detector relative to the sample. A measurement circuit measures values of the top and bottom peaks of the displacement signal. A CPU calculates the amount of the offset component according to the measured value of the top and bottom peaks and outputs a compensative signal based on the calculated amount of the offset component to the driver so that the driver shifts the detector relative to the sample according to the compensative signal to cancel the deformation of the sample to thereby remove the offset component from the displacement signal.

Abstract: In the radio communication system for performing a communication in the idle channel selected from a plurality of frequency channels, the originating call station transmits the station identification code to specify the distant station together with the idle channel data to be actually communicated, and the distant station designated by the station identification code shifts to the designated idle channel, and the communication is executed between two stations. During communication in a certain channel between two stations, in the case where a radio interference occurs in this channel and it is intended to shift to other channel, one station transmits the other channel data in the communication channel and the other station receives it, and the communication is continued each other in the other channel.
