摘要： A protection apparatus of a load circuit sets a threshold temperature at a lower temperature than an allowed temperature of an electric wire for use in the load circuit, and estimates a temperature of the electric wire based on an ambient temperature, a load current and a time while the load current is flowing through the electric wire. Then, in the case where the estimated temperature has reached the threshold temperature, a semiconductor relay (S1) is broken. As a result, in the case where such an electric wire temperature has risen owing to an occurrence of an overcurrent, and the like, the circuit is surely protected at the point of time before the electric wire temperature reaches the allowed temperature. Therefore, a fuse used in a conventional load circuit becomes unnecessary.

摘要： A protection device protecting a load circuit by shutting off a power thereof depending on an estimated present temperature of a wire provided in the load circuit to connect a load. The protection device has a first temperature estimation device estimating a rising temperature of a conductor including the wire based on both a current in the conductor and thermal properties of the conductor, a second temperature estimation device estimating a falling temperature of the conductor based on the thermal properties, a third temperature estimation device estimating an arc-induced rising temperature of the conductor when arcing occurs in the conductor, and a fourth temperature estimation device estimating the present temperature of the conductor deduced from the above estimated temperatures. If the estimated temperature exceeds a predetermined allowable temperature, the protection device shut off the power of the load circuit.

摘要： A rectangular cartridge that is substantially common in shape and external size with a disc cartridge in which a flexible magnetic disc with a diameter of 3.5 inches is accommodated, wherein at one side of the cartridge there is formed an insertion hole which permits insertion of a substantially rectangular plate-shaped memory and is adapted so that the plate-shaped memory is inserted with the short side as the insertion side. Further, there is formed a memory attaching portion substantially in correspondence with a long side of the plate-shaped memory in a manner continuous to the memory insertion hole and in parallel to the side adjacent to the side where the memory insertion hole is formed. In addition, a group of terminals for connection to terminals of the plate-shaped memory are provided at the terminating portion of the memory attaching portion. The cartridge is intended to be loaded into a recording and/or reproducing apparatus in the state where the plate-shaped memory is attached to the memory attaching portion. Thus, recording and/or reproduction of information signals with respect to the plate-shaped memory are carried out.
