Title: Recording method of servo signal
Inventor: TAKEDA RITSU
IPC: H04N5/7826
Filed: 1981-11-04
Abstract: PURPOSE:To realize the track positioning control with high precision and high reliability, by magnetizing in the width direction of a magnetic tape prior to the recording by plural gaps. CONSTITUTION:A rotary head 2 scans the center of a servo signal magnetizing pattern 14 prior to a track 2N, and a line 20, i.e., the output of a full-wave rectifying circuit 22 is produced. The signal of the line 20 drives a comparator 23, and only the pulse of a large amplitude is supplied to a 2-way counter circuit 24. Then the output 29 of the comparator 23 drives a pulse interval deciding circuit 25 and detects the pulse of small intervals which exist at the center of the servo pattern. The circuit 24 is switched to a subtraction mode from an addition mode, and the final value of the circuit 24 shows zero. When the head 2 starts a scan due to disturbance, etc., the signals are produced to the line 20. Thus the circuit 24 displays a position shift degree on a line 30 in the form of the negative counting value.

Title: Dialysis apparatus and spacer element thereof
Inventor: SUTEFUAN RICHIYAADO ATSUSHIYU
IPC: A61M1/22
Filed: 1981-11-02
Abstract: A reciprocating dialyzer is described for use as an artificial kidney or other extracorporeal mass transfer device. A dialyzer unit includes a membrane package having an aligned pair of thin semi-permeable membranes forming a chamber between the interior faces to receive fluid (such as blood) to be treated, and spacing elements in dialysate chambers at the exterior faces of the membranes which contact the membranes and limit their expansion, while allowing chemical transfer to the dialysate slurry. A plurality of such treatment units received between spaced plates comprises a dialyzer. Blood flow into and out of the membrane packages is through a central conduit, with free slurry being introduced and withdrawn from the dialysate chamber at the periphery of each unit. The spacing elements are flexible and of plastic with molded, porous or mesh material modified to provide central and rim seals as well as membrane engaging faces designed to limit membrane displacement and cause formation of a thin blood column while not unduly masking the membrane surfaces and allowing slurry flow at all times including when the blood chamber is filled with blood. Certain spacing elements also allow emptying of blood from the dialyzer without need for positive pressure on the fluid outside the dialyzer.
