Patent JP-H03190599-A (JP)
Title: Automatic voltage regulator for ac generator
Inventor: KATO TADASHI
IPC: H02P9/14
Filed: 1989-12-18
Abstract: PURPOSE:To stabilize output without sacrifice of the capacity of an exciting winding by detecting a load current and switching the set value of a voltage detecting circuit between the cases where thus detected load current is lower than a reference value and higher than the reference value. CONSTITUTION:A current detector C continuously detects the load current. When the load current exceeds a preset reference value, a current detecting circuit 5 outputs a set voltage switching command signal. A set voltage switching circuit 6 switches the set value of a voltage detecting circuit 2 to a second set value lower than a first set value. The second set value lower than the output voltage is sustained through the operation of the voltage detecting circuit 2 and an exciting current supply stop circuit 3 under this state. Consequently, the output does not increase in proportion to the load, and thereby the prime mover for the generator is prevented from entering into overload state. By such arrangement, a stabilized output can be obtained without sacrifice of the exciting capacity of an exciting winding A2.

Filed: 1990-11-30
Abstract: PURPOSE:To immediately play back a program which has been videotaped by means of a timer by installing a circuit which automatically detects the beginning of a videotaped program in order to play back the program after it has been videotaped by means of the timer. CONSTITUTION:A signal is input to a timer 2 from an operating key 1. When a changeover switch 9 is set to an OFF state, a videotaping operation is performed by means of the timer. When the changeover switch 9 is set to an ON state and the videotaping reservation time by means of the timer exceeds the residual amount of a magnetic tape 8, the timer 2 instructs a drive circuit 7 to rewind the magnetic tape 8 via a system control circuit 4. At the starting time of a videotaping operation, the timer 2 sends information on a tuning operation to a tuner 3. The system control circuit 4 obtains information on the start of the videotaping operation from the timer 2 and instructs a videotaping mode. At the end time of the videotaping operation, information on the stop of the videotaping operation is sent to the system control circuit 4 from the timer 2, and instructs the drive circuit 7 and a signal processing circuit 6 to stop the videotaping operation and to rewind back to the beginning of a videotaped program. Thereby, the videotaped program can be played back immediately after the videotaping operation by means of the timer has been performed.

Title: Production of grain-oriented silicon steel sheet
Inventor: SHIMADA KAZUO
IPC: C21D8/12
Filed: 1987-12-28
Abstract: PURPOSE:To produce the title grain-oriented silicon steel sheet free of the variance in the magnetic characteristic by applying a sulfide on the surface of a cold-rolled silicon-contg. steel sheet with a specified coating amt. distribution, applying an MgO annealing separating agent, and then applying secondary recrystallization annealing and purification annealing to the steel sheet. CONSTITUTION:A silicon-contg. steel slab is heated and then hot-rolled. One cold rolling or the two cold rolling including process annealing are then applied, and the steel sheet is finished to the final thickness. Decarburization and primary recrystallization annealing are applied to the cold-rolled steel sheet. An annealing separating agent consisting essentially of MgO is applied on the steel sheet surface, and then the secondary recrystallization annealing and purification annealing are applied. In the above-mentioned process, when the amt. of the sulfide such as MgSO4 to be applied on the region within a 100-300mm distance from the edge of the steel sheet on the surface of the steel surface after the decarburization and primary recrystallization annealing is denoted by (a) g/m<2> and that on the central part of the steel sheet other than the above-mentioned region by (b) g/m<2>, 1.3<=a/b<=10.0 must be satisfied. The sulfide is preferably mixed into the annealing separating agent, and used. By this method, a uniform secondary recrystallized structure is formed, and a grain-oriented silicon steel sheet free from variance in magnetic characteristic is obtained.

IPC: H05B3/56
Filed: 1990-11-30
Abstract: PURPOSE:To restrain a heating value from reducing when the size of a heated element is small or when a feeder is wound around the angle portion of the angular heated element by providing a braided heating element which is braided while wrapping the feeder with a fiber element wire of semiconductive material and an insulating coating which encircles the braided heating element and the feeder. CONSTITUTION:Two core wires 3 for a fiber element wire 40 are wrapped into a braided structure. The element wire 40 of a semiconductive heating element in a braided structure is put in point or line contact with two core wires 2 at many places via an insulating coating 5 and electrically connected thereto, and an electric heating cable 1 is wired along a pipe in which fluid flows. As the heating element 4 is in a braided structure, the application of external force causes dispersed tension which brings about less change in a resistance value. It is thus possible to restrain a heating value from reducing and affect no heat retaining property of a small-size pipe.

Title: Ic card
Inventor: KUMANO SHIGEO
IPC: B42D15/10
Filed: 1990-11-30
Abstract: PURPOSE:To prevent the destruction of the IC chip in an IC module and the disconnection of a bonding wire by cutting a plurality of slits in the card base material surrounding an IC module loaded part so as to at least doubly surround the IC module loaded part to form a buffer part and absorbing bending at this buffer part. CONSTITUTION:Two slits 3 are formed to a card base material in parallel to two sides of an IC module 2. Therefore, the IC module 2 is doubly surrounded by the slits 3 and a buffer part 4 exerting buffering action on the bending of the IC module 2 is formed between the slits 3. Therefore, even when large bending stress acts on an IC card A, the bending of the IC card A is absorbed by the buffer part 4 and, as a result, bending stress is hardly transmitted to the IC module area. By this constitution, the destruction of an IC chip and the disconnection of a bonding wire can be prevented.
