摘要： PROBLEM TO BE SOLVED: To provide a new temperature abnormality detection component and a temperature abnormality detector capable of rapidly detecting and determining the presence and position of an abnormal heat generation phenomenon by a smell and coloration. SOLUTION: A smell generation substance 3a and a smoke generation substance 3b are housed in a housing case 2 with an effusing port 4 formed, and the effusing port 4 is sealed by a lid body 5 formed of a low-melting substance. Thereby, when a heat generation position used for a monitoring object is overheated, the lid body 5 is melted down by its heat to open the effusing port 4 and smoke is generated along with a smell from the effusing port 4, so that the phenomenon and the position thereof can easily be detected and determined.

摘要： PURPOSE:To generate a snake on a power cable in accordance with a temperature rise of the power cable after laying by polygonally forming a winding drum of a cable drum, by inserting a spacer in every step of winding the power cable about a round winding drum. CONSTITUTION:A premanufactured power cable 1 is wound about a cable drum 2 having a sectionally polygonal winding drum 3 in layers, and bent parts 1a angularly bent at fixed intervals are formed on a wound-about power cable so as to produce starting for generating a snake to the power cable. When the power cable having formed bent parts are drawn out from the cable drum, it takes a form of a power cable 1' shown by a chain because of a remaining winding habit. When this power cable 1' is, for example, in a straight line laid, inside a duct line, the bent part is hard to become straight so as to take a state shown by a full line. When a current is flown through the power cable to cause thermal stress due to heating, a snake state is generated having bent parts as nucleuses.

摘要： PROBLEM TO BE SOLVED: To provide a smell detection type heat monitoring system capable of expanding a use range by allowing the usage of temperature detection in an opened space at a practical level without limiting the usage in a closed space. SOLUTION: This smell detection type heat monitoring system has a smell generation component 1 composed by enclosing a smell generation substance in a barrier layer for restraining diffusion of the smell generation substance, and used for monitoring temperature by breaking the barrier layer of the smell generation component by setting the temperature to a predetermined value or above to leak the smell generation substance outside the barrier layer and thereby diffusing it into the air and by detecting its smell by a smell sensor detection part 7 installed in a smell sensor body 6. The smell generation component 1 is attached to the smell sensor body 6.

摘要： PROBLEM TO BE SOLVED: To provide a spring-type compact slip-down preventive device for a CV cable which can reduce a necessary space in the circumferential direction thereof by devising the arrangement of springs for tightening cable holding members radially to enable the installation in a small dimension duct. SOLUTION: Guide bolts are extended in duct inlet metal fittings in the axial direction of a CV cable. Half-divided cable holding members linked with the guide bolts via the springs are tightened radially by the springs to hold the CV cable so as not to move in the axial direction of the cable. The springs for tightening the cable radially are provided on and under the coupling flanges of the cable holding members. Plates for holding the springs for tightening the cable radially are integrally formed on the cable holding members.

摘要： PROBLEM TO BE SOLVED: To distribute telescopic absorption ratio of each string freely by providing an action point for dividing elongation/contraction at a middle point of the arm of a pantograph for dividing elongation/contraction. SOLUTION: A pantograph 5 is provided through rods 3, 4 between the fixed side (cable supporting base 1) and the movable side (bridge side: cable supporting base 2) and an action point for dividing elongation/contraction is provided at a middle point of the arm of the pantograph 5. The action point is arranged to insert a protrusion 51 on the arm of the pantograph 5 slidably into an elongated hole 61 made in a cable supporting member 6 intersecting the arm of the pantograph 5. According to the structure, elongation/contraction can be absorbed little at a limited space in a bridge and absorbed much at an unlimited space and thereby elongation/contraction being transmitted can be divided freely.

摘要： PURPOSE:To provide possibility of change of snaked shape in a duct without enlarging the outside dia. of a cable by compressing and fixing compressive sleeves to a conductor at a certain spacing in its longitudinal direction so that the same as the conductor outside dia. is obtained. CONSTITUTION:Compressive sleeves 4, 4, 4... are compressed and fixed to a conductor 2 at a certain spacing in its longitudinal direction so that the same as the conductor outside dia. is obtained. When current feed is commenced through a power cable 1 laid in a duct 5, the conductor 2 runs temperature owing to Joule's heat so as to elongate in the longitudinal direction, but this is received by a cable fixing device 6 and substituted in the duct 5 with the compressive load in the longitudinal direction, i.e., the thermal stress. Those parts having a relatively small rigidity which exist here and there between the compressing/fixing parts of the sleeves 4 are bent by the thermal stress to cause snake formation of sine waveform in the duct 5, and therewith the elongating portion of the cable is absorbed, so that change of the snaked shape in the duct can be made without enlarging the outside dia. of the cable.
