Title: Manufacture of plastic molded form
Inventor: ITO SHUJI
IPC: B29C39/38
Filed: 1991-03-06
Abstract: PURPOSE:To facilitate mold release by lowering the adhesion of a molded form and a section for casting up to a roper value in the manufacture of the plastic molded form by casting. CONSTITUTION:An inert fluid having the boiling point higher than a polymerization temperature for curing a molding material 4 and not related to a polymerization reaction is blended previously to the liquefied molding material 4 used for manufacturing a plastic molded form. Since the inert fluid is not related to polymerization, the inert fluid is extruded from the inside of the molding material in the polymerization process of the liquefied molding material 4. Consequently, when the polymerization process is completed, the layer of the inert fluid is formed among the molding material and sections 2, 2'. Since there is the layer, the molding material can be released easily from the sections 2, 2'.

Title: Control device for engine
Inventor: ENDO KOJI
IPC: F02D41/08
Filed: 1992-02-26
Abstract: PURPOSE:To reduce the generation of hammering noise during a starting, in a device to effect delay control of an ignition timing by delaying decision of an idling period. CONSTITUTION:A throttle sensor 31 detects full closing of a throttle valve 19. A starter switch 39 detects the starting of an engine 1. An idling period is decided by an ECU 51 after a laps of a given delay time starting from detection of full closing by means of the throttle sensor 31. At the idling period, control of the ignition timing of the engine 1 is executed based on an ignition timing angle on the angle of delay side at which generating torque different from that during non-idling is suppressed. Further, the ECU 51 sets a delay time in decision during idling to a low value when a period does not exceed a given period starting from detection of the starting of the engine 1 by means of a starter switch 39. Thus, in case of right after a starting, rapid decision of idling is effected and control of an ignition timing is carried out with characteristics wherein generating torque corresponding to an idling period is suppressed.

Filed: 1994-02-16
Abstract: PURPOSE:To improve the quality of a cast slab by blowing inert gas from the bottom part of a tundish and also, coating the molten steel surface with a fusible insulating material, at the time of pouring the molten steel into a tundish from a ladle. CONSTITUTION:At the time of starting pouring of the molten steel 4 from the ladle 3 by beforehand putting the fusible insulating material 2 into the tundish 1, Ar bubble 9 from the bottom part 6 in the tundish 1 is blown into the molten steel 4. As a floculated aggregation of inclusion is promoted by stirring force of the Ar gas 9 blowing and also, the inclusion is stuck to the surrounding of the bubble itself, the Ar gas blowing has the effect quickening the float-up and separating speed of the inclusion. Further, the Ar gas blowing has the effect quickening the reducing speed of the total oxygen quantity (inclusion concn.) and the use of the fusible insulating material has the effect lowering the reaching value of the total oxygen quantity. By this method, the most vigorous contamination of the molten steel at the initial stage of the casting is quickly reduced and further, the removal effect of the inclusion in the tundish 1 can be improved.

Filed: 1981-03-21
Abstract: PURPOSE:To reduce the burden in maintenance of lines, by monitoring the state of line connection with simple constitution, in a reception section of a data communicating system using a bipolar potential. CONSTITUTION:When a normal data signal is transmitted from a transmitter (not shown), since both polarities of potential are produced with a prescribed period, the same polarity of signals are obtained in detector 202 and 203.
