Title: Automatic winder
Inventor: UMEDA KUNIO
IPC: B65H54/28
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To provide a releasable package in an automatic winder in which winding and traversing are carried out by respective drive sources. SOLUTION: An automatic winder drives a package drive drum 6 and the a feather traverse device 10 by means of respective drive sources 8, 15. With this arrangement, a second traverse device 17 is used only when the operations of the package drive drum 6 and the feather traverse device 10 are started up. Upon splice of yarns, replacement of yarn feed bobbins or the like, the second traverse device 17 carries out traversing if the synchronization cannot be taken between the package drive drum 6 and the feather traverse device 10, instead of the feather traverse device 10, and accordingly, the winding can be made with no disturbance during traversing. Thereby it is possible to enhance the release ability of the package 3.

IPC: A61B5/02
Filed: 1988-03-15
Abstract: PURPOSE:To accurately detect a pulse wave by removing an unnecessary wavelength, by mounting an outer frame for shielding disturbance light, the light emitting part and light detection part arranged in said outer frame and detecting the blood flow state of a fingertip and a filter permitting only transmitted light detecting the pulse wave of the fingertip to penetrate through the light detection part. CONSTITUTION:A filter 2 has function for permitting only transmitted light detecting the pulse wave of a fingertip to penetrate through a light detection part 3 and actually permits only transmitted light having a wavelength of 600nm or more to penetrate and, for example, it is composed of thallium bromoiodide. The light emitted from a light emitting part 1 is allowed to irradiate a fingertip 6. A change in the pulse wave of the fingertip 6 is grasped as the change of hemoglobin in blood and displayed as a change in a wavelength of 600nm or more. The spectral sensitivity of the light detection part 3 is set so as to detect light having a wavelength of 400-800nm and attenuated in a chevron-shape around about 630nm. By the presence of the filter 2, light having a wavelength of 600nm or more is transmitted while light having a wavelength of below 600nm is blocked and, therefore, only the change in the pulse wave of the fingertip is detected.
