摘要:
A core cord is inserted into coil-shaped fastener elements made of thermoplastic resin, and the fastener elements are sewn onto a fastener tape by multi-thread chain stitch. Yarn mainly made of thermally meltable synthetic fiber is used for looper thread of multi-thread chain stitch, while yarn of fiber which is not or less meltable is used for needle thread. Entangling points of the looper thread and the needle thread are disposed on the core cord. The looper thread is thermally melted to form melted portions where the looper thread and the needle thread entangle with each other at the entangling points. As a result, melted portions which have become monofilamentary are formed on the fastener elements or no sewing yarn is on the fastener elements due to thermal melting. Thus, there is no fear of cutting of the sewing yarn due to sliding of a slider and the slide fastener is abrasive resistant. The coil-shaped fastener elements is firmly attached to the fastener tape by using such thermally meltable looper thread.

A radiation image detector with improved readout efficiency. The detector records a radiation image by generating and storing electric charges when irradiated with radiation, and the image is read out by irradiating readout light. The detector includes first line electrodes and second line electrodes disposed alternately with each other. An opaque line insulator that blocks the readout light is provided on each side face extending in the longitudinal direction of each second line electrode. The insulator has a width smaller than the distance between the first and second line electrodes. This arrangement allows the electric charges in the area of the photoconductive layer adjacent to the side faces of the first line electrodes to be fully discharged, and the electric charges in the area of the photoconductive layer adjacent to the side faces of the second line electrodes to be prevented from discharging.
