Filed: 1988-01-12
Abstract: PURPOSE:To reduce tape traveling resistance and to reduce oscillation in the width direction of a tape by forming a tape guide with a self-guide roller. CONSTITUTION:A tape traveling control part 20a of a self-guide roller 20 held at a fixed inclined angle by a supporting body 21 is rotated in an inverse direction to the traveling direction of a tape 4. When the rotation of the control part 20a is changed and the rotation of the roller 20 and a relative speed by the traveling of the tape 4 are controlled, the tape 4 is alienated from the control part 20a at a relative speed V1, the air layer of several mu is formed, a friction coefficient is reduced suddenly, it becomes low friction an after a relative speed V2, it becomes the fixed low friction without a relation with the rotational number of times of the control part 20a. Then, when the rotational number of times of the control part 20a is controlled and the fixed speed between the speeds V1 and V2 is selected, the rising and falling phenomena of the tape 4 become small remarkably. As the result, tape traveling resistance is reduced, the oscillation in the width direction of the tape is reduced remarkably, and the tape can be raveled stably with switching the direction in a three- dimensional direction.

Title: Turbidimeter
Inventor: TAKASHIMA KAZUO
IPC: G01N21/47
Filed: 1981-01-13
Abstract: PURPOSE:To decrease the attenuation of detector output at a high turbidity part and to widen a measurement extent, by arranging a detector and a light source so as to accord an irradiation optical axis with a detection optical axis. CONSTITUTION:A half of luminous flux from a light source 1 is passed through a semitransparent mirror 6 and is irradiated to a measurement object liquid 3. Light among this luminous flux which is scattered to the rear side by the liquid 3 and reflected by the mirror 6 is made incident to a detector 4. This incident light is operated by a processing circuit 5 to obtain the turbidity of the liquid 3. By providing such semitransparent mirror, the output signal of the detector is not influenced by the distance between the detector and light source, because it is constituted that an optical axis of scattered light photodetected by the detector is equalized to an irradiation optical axis from the light source and a regular reflection is performed. As a result, the attenuation of the output of the detector 4 at a high turbidity part is eliminated and the turbidity measurement in a wide range is made possible.
