IPC: H02K3/04
Filed: 1983-11-15
Abstract: PURPOSE:To always obtain an adequate strand arranging state by disposing extrafine wires between the strands on the outer peripheral side of a sole layer coil. CONSTITUTION:An integrated sheet formed by aligning strands corresponding to the number of turns of a coil is spirally wound to form two types of coil cylinders of thick and thin diameters. The cylinders are cut in the suitable size to form sole layer coils for outer and inner layers, which are engaged and superposed to form a coil for a coreless motor. In this case, extrafine wires 5 of copper or nickel are engaged between the strands 1 on the outer peripheral side at the sole layer coils 3, 4 of the outer and inner layers to form to always form a gap (delta) between the strands 1. Thus, when the sole layer coils for the inner and outer layers are formed, the strands are always regularly arranged in the sole layer coil.

IPC: G06K13/06
Filed: 1994-09-09
Abstract: PURPOSE: To prevent the invasion of dust and to enable the preservation and holding of the device inside a pocket or a bag by pushing a first lid member back to a prescribed position with an IC card when the IC card is inserted from an inserting port. CONSTITUTION: This device is provided with structure to move the lid part of an IC card reader backward when the lid part is pushed with an IC card 2 and structure to automatically close the IC card inserting port of the IC card reader 1 with the lid part when the device is not used. When a second lid member 4 is pushed with a first lid member, perpendicular force is generated in the inserting direction of the IC card 2. Since the second lid member 4 is provided with structure to be moved only in the direction of generating the perpendicular force against the inserting direction of the IC card 2, when the first lid member is pushed and the IC card 2 is inserted to the prescribed position, the second lid member 4 is opened. Therefore, even when the dust of the pocket or the like enters the IC card reader 1 during the preservation, each time contents are read out, the internal dust is pushed outside.
