    摘要: In a system for recording and reproducing digital signals on a magnetic tape using a rotary head, in which the signals are recorded as a series of slanted tracks without guard bands between adjacent slanted tracks, a pilot signal that was recorded during the recording process is used to control the tracking of the playback head. The pilot signal is recorded at a specific position in a specific pilot signal record region, independent from the region of the track at which the informational signal is recorded and the pilot signal is arranged at a predetermined position or positions being a specified distance from an end of each track in its longitudinal direction and only alternate tracks receive such pilot signal. When the recorded tracks are reproduced by a rotary playback head having a tracing width that is greater than the width of the track, the pilot signals from the adjacent tracks will be detected and can be compared in level, with the comparison output being used to control the tracking of the rotary playback head.

    摘要: Disclosed is an extracting solution for use in the extraction of a residual veterinary drug in livestock product or seafood. The extracting solution contains 0.05 to 1% of metaphosphoric acid and comprises a buffer solution of pH 5.5 to 7.5. The extracting solution can extract plural veterinary drugs at the same time, and can be used preferably used for the extraction when the residual veterinary drug is an antibacterial substance. By using the extracting solution, it becomes possible to extract plural veterinary drugs efficiently at the same time without impairment of stability because of its neutral pH range. Hence, the extracting solution enables to determine a residual veterinary drug in livestock product or seafood rapidly in a simple manner.

    摘要: An abnormality detection device includes small motion sensors that detect small motions of a person in a house; a data collecting unit that collects and stores sensor signals from the small motion sensors as sensor patterns, and a Markov chain operating unit 33 that transforms the sensor patterns into a cluster sequence by vector-quantizing input patterns which are obtained by averaging and normalizing the sensor patterns, and calculates a transition number matrix and a duration time distribution of a Markov and so on using a Markov chain model. The abnormality detection device also includes a comparing unit that calculates a characteristic amount (Euclid distance and average log likelihood in an appearance frequency of a Markov chain and an average log likelihood to the duration time distribution of a Markov chain) of a sample activity as against a daily activity based on the obtained transition number matrix and the duration time distribution and so on.

    摘要: A magnetic head drive circuit for driving a coil of the magnetic head performing opto-magnetic recording, is disclosed. According to the present invention, the switching elements are actuated on the basis of driving signals for commutatingly connecting three power sources presenting three different potentials to both ends of a coil of the magnetic head such that the potential difference across both ends of the coil at the time of magnetic field inversion is larger than that at the time of generation of the stationary magnetic field to render the rise time of the current flowing in the coil sufficiently short.

    摘要: The photographic projector is adapted that a lens seating plate to which a projecting lens is fixed is provided so that it maybe moved in the optical direction with respect to the lens holder. When the base of the lens holder reaches even to the end of its stroke, distance of the original picture or that of the picture image from the base of the lens holder is still deficient in reaching to the value which corresponds to desired magnification, the lens seating plate is moved a desired amount along the optical axis so that the lens may be set up a position corresponding to any desired magnification.
