Abstract: A chip-type fuse includes a plated-shape fusible body (26). The fusible body (26) has internal electrodes (28 and 30) facing toward the center of the straight line from both ends of the straight line, respectively and has a fusible portion (32) formed between the internal electrodes (28 and 30) and integrated with them. The fusible body is housed into a casing (2). Protrusions (38 and 40) protrude from the parts of the both ends of the internal electrodes (28 and 30). The protrusions (38 and 40) are covered with plating layers (50 and 52).

Abstract: A terminal-integrated fuse (2) includes two planar members (10), (10) serving as terminals for mounting on a substrate. The two planar members (10), (10) are spaced on a same horizontal plane. A fuse body (4) is located on a horizontal plane at a level different from the level of the said horizontal plane and between the planar members (10), (10). The fuse body (4) is formed integral with the planar members (10), (10). A casing (14) has side walls (18), (20) and end walls (22), (24) disposed around an opening. The fuse body (4) is positioned in the casing (14), and the two planar members (10, (10) are in contact with the end walls (22), (24), respectively. An arc suppressing material portion (26) is provided in the casing (14) in such a manner the fuse body (4) is embedded therein.

Abstract: A moisture detector of closed case type according to a heat capacity method is realized by a relatively simple constitution. The moisture detector includes a first temperature sensor for sensing temperature of a detection target; a second temperature sensor for sensing the temperature of the detection target; a small heater for heating the second temperature sensor; and a processing unit for obtaining information relating to moisture percentage in the detection target on the basis of a signal outputted from the first temperature sensor and a signal outputted from the second temperature sensor heated by the small heater.
