Filed: 1984-09-20
Abstract: PURPOSE:To reduce power consumption by controlling its supply current to an amplifier supplying a recording current to a rotary head so as to be interrupted except at a time when at least the rotary head comes into contact with a tape. CONSTITUTION:Switches SA, SB switching the supply power to amplifiers GA, GB for drive are provided at magnetic heads MA, MB and the switch is controlled for switching by using signals (servo signals) V, W obtained from a rotary phase detector of the rotary drum. That is, when any of the signals V, W is at H, the switch SA is closed, a power supply VCC is applied to the amplifier GA, and when the signal V is logical L, the switch SB is closed, a power is applied to the amplifier GB so as to attain control so that no power is applied to the amplifier of a magnetic head not coming into contact with the tape. Thus, the power consumption is reduced, the crosstalk at reproduction is reduced and noise due to suprious radiation is lowered.

Abstract: PURPOSE:To obtain an inexpensive apparatus with a simple construction which enables separating operation in a short time, by supporting a cylinder having a magnet inside rotatably in a cylindrical container while a magnet is arranged near the container in such a manner as to rotate centered on a shaft parallel with the axis thereof. CONSTITUTION:A cylinder 2 having a magnet 6 inside is supported concentrically and rotatably in a cylindrical container 1 and a magnet 7 is arranged near the container 1 to be rotated by a motor 8 centered on a shaft parallel with the axis thereof. Then, when the cylinder 2 rotates, a solid-phase liquid existing in a circular space between the container 1 and the cylinder 2 moves together by a friction force at the part contacting the cylinder 2 while being kept at rest at the part contacting the container 1 which causes a violent agitation, but the axial motion thereof is restricted strictly. At this point, when a small amount of a mobile phase liquid is injected from a sample injector 3, it floats or settles in the solid-phase liquid while spiralling as rotary particle. This achieves a distributive balancing of a solute between the mobile-phase liquid and the solid-phase liquid in a very short space of time.
