摘要： A recording/reproducing apparatus in which the number of revolutions of a recording head 14 is controlled depending on the frequency of the vertical synchronization signals for picture signals supplied from outside for digitally recording/reproducing picture data. It is not the recording head 14 but the playback head 16 whose number of revolutions is controlled in such manner during reproduction. In forming DRCK control signals employed for controlling the number of revolutions of the recording head, the frequency of the vertical synchronization signals for the picture signals supplied from outside is corrected so as to be within a range of offset of .+-.1% relative to the frequency of standard frequency vertical synchronization signals, and the DRCK control signals are formed based upon the vertical synchronization signals corrected in this manner. This permits picture data to be recorded so as to assure interchangeability between different apparatus of the same version, and makes it possible to improve the stability after phase capturing of, for example, a DRCKPLL circuit 34 designed to form the DRCK control signals.

摘要： A quantizing number is determined using multiple stages of code amount estimating circuits. Thus, an optimum quantizing number may be selected from among a number of quantizing numbers which is not limited to the number of code amount estimating circuits. The optimum quantizing number is used to quantize a set of blocks of orthogonally transformed image data. The quantized data are encoded using a variable length code. The optimum quantizing number is the one which results in the greatest amount of data that is within a predetermined threshold, permitting an amount of encoded data to be recorded on a magnetic tape in a fixed format.

摘要： A shock-absorbing member is fixed to top brackets at the end of a boom opposite to the top of an impact tool. A stopper member is secured to one of the bottom of the shock-absorbing member and the top of the impact tool and the other of the same is formed with a guide recess in which the stopper member is vertically slidable. When the tip of the chisel of the impact tool is pressed hard against an object to be crushed, no turning force will be applied to vibration-damping support members which support the impact tool, thereby preventing the support members from breaking.

摘要： An impact tool for striking a tool such as a chisel includes a piston mounted in a cylinder. Upper, middle and lower chambers are formed therebetween. Pressure oil is fed into and discharged from the middle and lower chambers to reciprocate the piston in the cylinder under oil pressure. During a downward stroke of the piston, the oil pressure in the lower chamber is kept low. But just before it strikes a tool, the oil pressure in the lower chamber is adapted to increase so as to prevent what is called cavitation or prevent air bubbles mixed in the pressure oil in the lower chamber from growing suddenly owing to a sharp drop in the oil pressure which is caused by the rebound of the piston after striking the tool.

摘要： A digital capstan servo circuit controls the rotation of a capstan motor used for sending a recording medium of a recording apparatus having a recording circuit for recording a plurality of pilot signals instead of CTL signals used for a tracking servo of the capstan motor in a reproducing mode. The pilot signals have different frequencies respectively and are recorded under being mixed with a video signal on video tracks. In the recording mode, a rotation speed information obtained from a counter of which a counting value is latched by a latch pulse produced from FG signals which are generated synchronously with the capstan motor and a rotation phase information obtained from the counter of which a counting value is latched by a latch pulse produced from an oscillator, an output signal of the oscillator having the same frequency as that of but a different phase from as that of the FG signals, are mixed to be a control signal of the capstan motor.

摘要： A device for removing a dump nut from a bolt. The dump nut consists of a casing having an upwardly diverging through-bore, a plurality of separated nut segments slidably inserted in the through-bore in the casing to define a threaded bore therein, and a spring inserted in the through-bore in the casing to constantly urge the nut segments in the downward direction. A bolt is inserted through the threaded bore defined by the nut segments. The nut removing device according to the invention consists of two cross-sectionally arcuate complementary members which are oscillatably joined together at their adjacent side edges. In order to remove the nut from the bolt, the nut is turned in an untightening direction to a small extent, and the nut removing device is fitted around the exposed portion of the bolt. The device is then pushed upwardly to raise the nut segments against the spring. Thus, the nut can be removed from the bolt without turning the former over a great distance in the untightening direction toward the free end of the latter.
