摘要： A two speed or multi-speed video tape recorder of the conventional helical scan type in which the audio signal is capable of being recorded as a time compressed signal at one end of each helical video scan, or alternatively, in conventional longitudinal fashion by means of a stationary magnetic head engaging one edge of the tape.At low tape transport speeds, improved bandwidth (and therefore sound fidelity) is obtained by use of the time compression technique; while at higher transport speeds, there are advantages in utilizing the stationary audio head.Circuitry is provided to automatically utilize the time compression technique at lower tape transport speeds and the stationary head longitudinal recording technique at higher tape transport speeds. A pilot or cue signal is recorded on the tape, to automatically control the reproduction circuitry so that both types of recording methods can be interchanged on the same magnetic tape, with the reproducing circuitry switching accordingly between the two modes, as required.

摘要： A circuit for reproducing informaiton signals and four different tracking control pilot signals recorded on respective tracks on a magnetic tape and producing from the pilot signals a tracking error signal indicative of a relative positional deviation between each of a plurality of magnetic heads and each track of the tape. The circuit includes a balanced modulation circuit for successively multiplying reproductions of the pilot signals and a reference signal to produce a multiplication output signal having components corresponding to the respective pilot signals. Respective tuning circuits derive first and second signals from the multiplication output signal, having different frequency components and corresponding to different ones of the pilot signals. A level comparison circuit compares the first and second signals in level to produce a level-compared output signal whose value is indicative of the relative levels of the first and second signals, the level-compared output signal having respective portions corresponding to successive periods of reproducing signals on tracks on which different ones of the pilot signals are recorded. A further portion of this circuit time-divisionally extracts the values of levels of the level-compared output signal. A further comparator calculates the values of the differences between at least two of the extracted level values to produce the tracking error signal. The circuitry eliminates any variations in the tracking error signal which may be caused by any variations in mechanical height of the magnetic heads.

摘要： A device is provided for electronically editing and recording new signals on recorded tracks on a recording medium. Reproduction is started from the track just before an editing point and a magnetic head mounted on an electro-mechanical converting element traces the curvature of the reproducing track. A deviation amount of the electro-mechanical converting element upon reproduction of the track just before the editing point is detected by a strain detecting sensor mounted on the electro-mechanical converting element. The detection signal is sampled at a plurality of sample points and stored in a memory circuit. When the head reaches the editing point, the head is set into the recording mode. The electro-mechanical converting element on which the head is mounted is deviated in accordance with the curvature information of the reproducing track just before the editing point and, at the same time, a closed loop control is executed such that a strain pattern in the track scan which is detected by the strain sensor mounted on the converting element coincides with a strain pattern of the strain sensor upon reproduction of the track just before the editing point which was stored. Due to this, the curvature characteristics of the recorded tracks before and after the editing point are made to coincide.

摘要： There is provided a correction value generating means (15) which utilizes, as a correction value, the difference between a first tracking error signal provided by a first tracking error detecting means (13) and a second tracking error signal provided by a second tracking error detecting means (10) where any one of first magnetic heads (3), (4) and second magnetic heads (5), (6) fitted through electric-mechanical transducing elements (7), (8) is in a state of reproducing, but the difference between the second tracking error signal of a recorded track being currently reproduced and the second tracking error signal preceding the recorded track is used as the correction value where the first magnetic heads (3), (4) are in a state of recording while the second magnetic heads (5), (6) are in a state of reproducing, so that the correction value can be used to correct a reference signal used to drive the electric-mechanical transducing elements thereby to control the electric-mechanical transducing elements (7), (8) whereby the first magnetic heads can during the recording scan the track so as to follow a curvature thereof to accomplish a favorable editing and recording wherein, even in a magnetic tape having bent tracks differing at the start and end points of the editing and recording, neither erasure of the tracks on respective sides of a joint nor insufficient erasure occur.

摘要： A rear suspension system for automobiles, comprising: a trailing arm pivoted to the automobile body at its front end and to a knuckle at its rear end; a first and a second lateral links extending laterally across an upper portion and a lower portion of the knuckle and the corresponding locations of the automobile body, respectively; and a third lateral link extending laterally across an intermediate position of the knuckle, located between the upper portion and the lower portion of the knuckle and behind a central axial line of a wheel axle of the knuckle, and the corresponding location of the automobile body. The second lateral link has a substantially same length as the third lateral link. Thus, the mounting positions of the lower end of the shock absorber can be lowered, and the resistance against the changes in the toe angle and the camber angle is increased. If the first lateral link is shorter than the second lateral link, the camber angle of the outer wheel of a vehicle making a turn can become negative so as to improve the cornering limit of the automobile.

摘要： This storage system is designed to refer to a translation lookaside buffer, a buffer address array and a buffer storage in parallel. The translation lookaside buffer translates a logical address requesting memory access into a real address. The buffer storage retains part of the data retained in blocks by main storage and outputs data from M blocks in accordance with the logical address to M aligners. The buffer address array retains the addresses in MS of the data stored in each of the blocks in the buffer storage, and outputs M addresses in accordance with the logical address. A comparator compares the real addresses from the translation lookaside buffer with the addresses from the buffer address array, selects one of the outputs from the aligners, and transfers that output to a processor.
