摘要:
A drop/insert selecting system for an optical transmission system has a decreased circuit scale, by providing a switching unit (4,4') having a plurality of input terminals for receiving a plurality of input channels and a plurality of output terminals, each of the input channels conveying a frame synchronization signal and a channel number. At at least one drop/insert unit (51,52,51',52') is provided for sequentially generating channel preselection signals until a frame synchronization is established and for dropping or inserting necessary signals from or into a corresponding one of the necessary channels incorporated into the drop/insert units when a frame synchronization is established. A channel selecting unit (6,6a,6b) is provided for generating a plurality of channel selecting signals in response to each of the channel preselection signals, each of the channel selecting signals functioning to connect each of the output terminals to one of the plurality of input terminals. The remaining output terminals of the switching unit are connected to through-channels to which no drop/insert units are connected.

Provided is a panel (3) for analysis having a chamber inside for transferring a sample liquid dispensed as a drop on an injection port (14). The injection port (14) is formed to protrude in a direction away from the chamber, a recessed section (12) is formed around the injection port (14), and the injection port (14) is arranged on the side of a rotating axis center (11) of a holding member (101) for the panel for analysis in an analyzer. Thus, even when a sample liquid is adhered around the injection port, contamination and shortage of the sample liquid can be prevented.

The present invention is to provide a tape-winding apparatus utilizing an adhesive tape-supplying device. The tape winding apparatus provides a smooth and a good appearance winding of the adhesive tape, which has a high extensibility and high adherence, around an object such as an electrical wire without stretch of the adhesive tape and difficulty of winding off the adhesive tape. The adhesive tape-supplying device includes an axle for rotatably supporting an adhesive tape reel; a rotating disk having the axle at the center thereof; a one-way bearing projecting near from an outer circumference of the rotating disk; and rotating means for rotating the one-way bearing and the rotating disk. The adhesive tape-supplying device includes a guide member disposed near the outer circumference of the rotating disk for accepting the adhesive tape from the one-way bearing.
