摘要:
A variable resistor having a short-circuiting member which is displaced in response to the generation of abnormally high heat in the resistance member of the variable resistor with a piece thereof in contact to short-circuit the input and output terminals of the resistance member. This results in a bypass for large current, so that a protection circuit in an output amplifier is operated to suspend the generation of heat.

A fader controlling variable resistor adapted to adjust the balance in sound volume of the right and left loudspeakers, or the front and rear loudspeakers. When abnormal heat is generated in a variable resistor in a fader control circuit, the sliding piece of the variable resistor is disconnected from the resistance member by the utilization of a thermo-plastic resin of a low-melting-point material is readily deformed or molten by heat, to prevent a fire attributed to the generation of heat therein. In one embodiment of the invention, the sliding piece is maintained in contact with the resistance member against its elastic force by a protrusion of thermo-plastic resin. When abnormally high heat is generated in the variable resistor, the protrusion is molten, and the sliding piece is disconnected from the resistance member or the conductor.

A semiconductor device has, in one embodiment, two wells of different conductivity types formed in a semiconductor substrate. The two wells are arranged to be adjacent to each other to form a junction therebetween. A field oxide film is formed to cover the junction at a main surface of the semiconductor substrate. Other field oxide films or field-shield isolation structures may be formed to isolate circuit elements from one another in the wells.

A moving handrail repair device includes a self-travelling means and a heating means mounted on the self-travelling means. The self-travelling means travels on a balustrade of a passenger conveyor along a longitudinal direction of a moving handrail. The heating means heats and melts a surface portion of the moving handrail. The surface portion of the moving handrail is formed of a thermoplastic material. In a case where the surface portion of the moving handrail is damaged, an object portion to be repaired of the surface portion is heated and melted, and then the object portion is re-hardened.

A ring network has first and second network connecting offices for connecting ring networks together and for dropping a signal from a terminal office. Each node of the ring network recognizes whether it is the first network connecting office based upon channel setting information. A first node, which has been recognized as being the first network connecting office, executes a squelch-table creation procedure between itself and other nodes based upon the channel setting information, thereby identifying a second node, which is the second network connecting office. The first node embeds office identification information in a squelch table of a protection channel and sends this information to the second node. The second node recognizes that it itself is the second network connecting office based upon the office identification information.

Network monitoring device and method whereby the user can be given an alarm before a guaranteed limit of packet routing is exceeded. Counting section counts the number of nodes based on packets exchanged between the nodes, and comparing section compares the node count with an allowable value. If the node count is larger than the allowable value, alarm output section outputs a message that the node count is excessively large.

An endless moving handrail for a passenger conveyor is formed by heating and connecting together both end portions of a handrail developed body with a connection die. The handrail developed body includes a core body that is made of a thermoplastic elastomer and has a substantially C-shaped cross section, a tensile body arranged inside the core body along a longitudinal direction of the core body, and a canvas arranged on an inner surface of the core body. In the moving handrail for a passenger conveyor, both the end portions of the handrail developed body heated with the connection die are formed as a handrail connection section. A bending stiffness of the handrail connection section is reduced from a longitudinal intermediate portion toward a longitudinal outer side of the handrail connection section.
