Abstract:
PROBLEM TO BE SOLVED: To provide a pressure-sensitive sensor capable of layering pressure-sensitive ink layers and electrodes with satisfactory productivity, facilitating control over the contact between the pressure-sensitive ink layers and the electrodes by a load, satisfactorily reproducing resistance values between the pressure-sensitive ink layers and the electrodes by the load, and highly accurately measuring pressure. SOLUTION: The pressure-sensitive sensor 40 includes a substrate film 31 formed by connecting trapezoidal shapes to a rectangular shape each from its four sides with their lower bottoms as connection lines in a plan-view shape; a pair of the electrodes 16a and 16b formed in a ring shape in the part of the rectangular shape of the substrate film 31 along its circumferential edge; and the pressure-sensitive ink layers 30 formed in the parts of the trapezoidal shapes of the substrate film 31 in such a way as to be in parallel with the pair of electrodes 16a and 16b. The pressure-sensitive ink layers 30 are layers of which electric characteristics change when pressed. With folding lines 50 indicated by the two-dot chain lines of (1) in Fig. 2 as axes, the parts of the trapezoidal shapes are folded to the inside in such a way that the pair of electrodes 16a ad 16b may come into contact with the pressure-sensitive ink layers 30.

Abstract:
PROBLEM TO BE SOLVED: To provide a touch panel comprising a pressure detection function which suppresses thickness and is capable of suppressing variation in sensitivity.SOLUTION: On a lower surface of an upper transparent substrate, a plurality of upper transparent electrodes are provided in a striped manner and on an upper surface of a lower transparent substrate, a plurality of lower transparent electrodes are provided in a striped manner across the upper transparent electrodes. A gap forming member is provided in an area where the upper transparent substrate and the lower transparent substrate are opposed, in such a manner as to form a gap between the upper transparent electrodes and the lower transparent electrodes. A transparent pressure-sensitive ink member is provided to cover at least either the upper transparent electrodes or the lower transparent electrodes. When external force is applied in a thickness direction of the upper transparent substrate, the transparent pressure-sensitive ink member is brought into contact with both the upper transparent electrodes and the lower transparent electrodes to conduct the both.

PROBLEM TO BE SOLVED: To provide a protection panel having a switch section on a surface-side substrate which does not become concave with time to prevent deterioration of appearance, while ensuring durability of a contact point, and to provide an electronic device.SOLUTION: The protection panel includes a pressure-sensitive conductive member 25 that is in contact with an upper electrode 6G for peripheral switch and a lower electrode 5G for peripheral switch and located in a through-hole 10 of a substrate adhesive layer 17. A force acting on a peripheral switch 12 is transmitted to the pressure-sensitive member through upper and lower electrode substrates, to supply current for electrically connecting the upper and lower electrodes.

Abstract:
PROBLEM TO BE SOLVED: To provide a heat-insulating cover for freight which does not damage the freight in the cover even if a large quantity of a coolant or exothermic material is used. SOLUTION: The heat-insulating cover for the freight is constituted of a skin material made of a heat-reflecting layer and/or a heat-insulating layer shaped to cover at least one of a top face, a bottom face and side faces of the freight and a holding region located inside the skin material for holding the coolant or the exothermic material. Therefore, the freight in the heat-insulating cover is not damaged even if a large quantity of the coolant or exothermic material is used. COPYRIGHT: (C)2004,JPO&NCIPI
