Filed: 1993-03-31
Abstract: PURPOSE:To provide a trigger circuit capable of surely firing the thyristor which can not obtain power from the high-voltage side without using a large- sized expensive transformer etc., as before. CONSTITUTION:A trigger power circuit 20 insulated from a low-voltage side through a transformer 3 is connected between the gate and the cathode of a thyristor used for a high-voltage system 2, through a photodetector 7 which is turned on or off by receiving light signals from an electricity-light conversion element 6 provided on the low-voltage side. When the photodetector 7 is turned on by a light signal, a trigger current is supplied to the gate of the thyristor 1, and the thyristor 1 is fired.

Title: Motor idling preventor for electronic wrist watch
Inventor: NAKAYAMA YASUAKI
IPC: G04C9/00
Filed: 1981-05-19
Abstract: PURPOSE:To prevent the idling of a motor by providing means of supplying current to apply an electromagnetic brake to a rotor with current running to a coil according to a signal from the detection of the oscillation of the rotor in  the functional mode other than normal pointer operation. CONSTITUTION:Pulling out the crown 1 stops a stepping motor. Then, with a pointer adjustment, a slip torque by a slip mechanism for a pointer ring train including a cylinder pinion to receive pointers and deceleration ring train is transmitted to a rotor 23 to move. When a Holl element 9 changes in the Holl voltage beyond a certain level, the output of a discrimination circuit 13 is inverted. The output of a ''H'' level is produced for two seconds from a timer circuit 14 to provide a driving signal to a driving circuit 7 for two seconds and  current flows through a coil 8 for two seconds. At this point, an FF circuit 7a  is left as intact so that current flows in the same directin as it does through the  coil 8 at the final stage of the normal pointer operaton. Therefore, the rotor 23  is retained firmly at rest by a magnetomotive force from the current of the coil 8, free from idling by a slip torque generated in the pointer adjustment.

Title: Method and apparatus for performing continuous surface treatment of rod-like elongated metal having metallic surface
Inventor: BORUKAA MIYUURAA
IPC: B23K20/00
Filed: 1993-03-31
Abstract: The invention relates to a process and apparatus for thermal surface treatment of wire rods with a metallic surface by means of an electric arc which rotates, magnetically driven, about the axis of the billet, the arc moving between an annular electrode (anode) and a billet taken through the latter and serving as cathode. According to the invention, the problem of developing improved measures for stabilizing the arc is solved, inter alia, in such a way that the rotation of the arc is achieved by means of a direct-current magnet arranged downstream of the annular electrode in the direction of running of the billet and, at the same time, the magnetic field induced by the direct-current magnet counteracts the effect of the arc root being taken along by the moving billet, and that the annular electrode current is divided into two part currents. The field of application is predominantly the thermal surface treatment of wire rod materials with a metallic surface.

Title: New thermoplastic elastomer reduced in compression set
Inventor: IBONAI MASARU
IPC: C08G69/48
Filed: 1993-03-10
Abstract: PURPOSE:To obtain a new elastomer reduced in permanent compression set and quickly recovering from strain by adding a polyfunctional epoxy compound as a crosslinking agent to a thermoplastic polyamide elastomer and extruding the mixture. CONSTITUTION:0.1-3phr polyfunctional epoxy compound (e.g. diglycidyl terephthalate) is added to a thermoplastic polyamide elastomer, and the resulting mixture is extruded, whereupon a crosslinking reaction takes place in the molding machine to give an elastomer reduced in permanent compression set and quickly recovering from strain. Any conventional polyamide elastomer is not satisfactory in respect of permanent compression set because it is not chemically crosslinked. However, since the above elastomer has the improved properties as described above, it can find wide applications in the areas where load withstading properties are necessary. Further, the operation is easy because the reaction can be accomplished in the extruder.
