Title: Sample cassette transfer apparatus
Inventor: WAKATAKE KOICHI
IPC: G01N35/04
Filed: 1988-07-20
Abstract: PURPOSE:To perform emergent examination in an extremely simple and rapid manner by controlling driving so that a sample cassette is transferred in a transfer passage so as to freely advance and recede. CONSTITUTION:When the necessity for emergent examination is generated on the way of the sampling work of a sample container for a general specimen, a switch 16 for emergent examination is turned ON at first. Then, a sample container for emergent examination is set to the sample container holding holes 21a1, 21b1 of a sample cassette C and, when the switch 16 is again turned ON, a control part Y allows the sample container for emergent examination held to the holding hole 21a1, 21b1 of the cassette C to advance to transfer the same to a sampling position S2 and predetermined operation is started. When the work is finished, the control part Y allows the cassette C to recede to perform driving control so that the next sample container of the interrupted sample container for the general specimen is set at a position S2. By this method, interrupted sampling work for the general specimen is reopened.

Abstract: PROBLEM TO BE SOLVED: To individually adjust the coupling rates of plural optical couplers by drawing all optical fiber couples at the same time while heating their fusion-spliced parts, and then drawing and adjusting the center parts of some optical fiber couples with heating at the same time while heating the peripheral parts of other optical fiber couples. SOLUTION: Optical fibers 2a and 3a which are exposed by removing batch coating layers at halfway parts of two four-fiber ribbons 2 and 3 are held one over the other so that their peripheral surfaces come into contact.

Here, laser beam is made incident on one-end sides of the optical fiber couples #1-#4 to monitor the coupling rates respectively.  Then, optical fiber couples whose coupling rates do not exceed a previously set threshold value are heated at their center parts where the coupling rates vary by drawing, and the optical fiber couples whose coupling rates exceed the threshold value are heated at their peripheral parts where the coupling rate do not vary by the drawing, thereby drawing the optical fiber couples so that the coupling rates of all the couples exceed the threshold value.
