Abstract: A massage machine is provided which is adapted for effective massage by initiating a pair of therapeutic fingers into a lateral movement toward or away from each other approximately simultaneously with the start of an upward or downward movement of the fingers.

Abstract: Supplied selectively to a recording system circuit of a VTR are a first component signal comprising three primary color signals R, G and B and a second component signal comprising a luminance signal Y and two types of color difference signals P.sub.B and P.sub.R. The first and the second component signals pass through a group of LPFs (1, 2, 3) having the same pass characteristics and then are A/D converted at the same sampling clock. The component signal converted into a digital signal is applied to a matrix circuit 11. Respective coefficients of the matrix circuit are switched according to a type of the inputted component signal, and as a result, a second digital component signal is always outputted at a fixed delay time from the matrix circuit. Two color signal data which are over-sampled included in the second digital component signal are applied to decimation digital filters 14 and 15 to reduce data densities thereof.

Abstract: A reproduced video signal of a VTR is applied to a jitter compensation circuit (100). The applied reproduced video signal is A/D converted by a phase modulated clock and after subjected to the adjustment of timing, the signal is written into a memory (4). A burst signal period is specified based on a timing of a horizontal synchronizing signal in the reproduced video signal and a jitter amount is detected based on a sampling phase of the A/D converted burst. Jitter compensation data is calculated based on this jitter amount. On this occasion, latest jitter compensation data is obtained based on the detected jitter amount and the jitter compensation data one horizontal period before. A timing for starting to write the A/D converted video data into the memory is defined based on high-order data of the calculated jitter compensation data, thereby cancelling large jitter components.
