Filed: 1993-04-14
Abstract: PURPOSE:To easily carry out the assembly of a inner race and a retainer and set a high critical point between the separation and nonseparation, even if the dimension of a member related to the nonseparated state of the inner race and the retainer is not controlled severely. CONSTITUTION:An engagement piece 7 which is flexible and has a nearly <-shaped section is installed on the inner periphery of a retainer 4, and an engagement groove 8 is formed on the outer periphery of an inner race 1, and when the retainer 4 and the inner race 1 are relatively moved so as to be separated each other, the engagement piece 7 is nipped between the engagement groove 8 and a ball 3 group through deflection.

Abstract: PURPOSE:To make cross talk inconspicuous by making a chroma signal into a signal having interline correlation through time-division multiplexing on simultaneous basis, and providing every track with a carrier offset which is a half as large as a horizontal synchronous frequency. CONSTITUTION:Switch circuits 45 and 46 are connected to black-circle sides when video tracks are traced or to white-circle sides when overlap tracks are traced. Signals of f1 and f3, and f2 and f4 are recorded on the video tracks 54 and 55 by heads 13 and 14, and the signals of f2 and f4, and f1 and f3 are recorded on the overlap tracks 56 and 57. The frequency of a frequency-modulated signal is set fh/2 higher by a carrier offset in a recording current spectrum; a peak synchronous frequency is (fs+fh/2), and a white peak frequency is (fw+ fh/2). When reproduced signals from the tracks 54 and 55 with t=t1 are denoted as Cos(omega1t+theta1) and Cos(omega2t+theta2), a demodulated cross talk signal is Cos{(omega1- omega2)t+theta1-theta2}. Reproduced signals from the tracks 54 and 55 with t=t1+1H are Cos(omega1t+theta1+DELTAtheta1) and Cos(omega2t+theta2+thetaDELTA2). Therefore, demodulated cross talk signals are inverted in phase, line by line, and become inconspicuous disturbance.
