Title: Production of collapsible sand core
IPC: B22C13/08
Filed: 1992-03-19
Abstract: PURPOSE:To obtain the sand core which does not break at the time of low-temp. casting with a sand core prototype molded by a shell mold method and has an excellent collapsibility by subjecting the sand core prototype formed by solidifying RCS to an alkaline treatment, then drying the sand core prototype by heating. CONSTITUTION:The sand core prototype is molded by using the resin coated sand formed by coating the sand with a synthetic resin of a carbolic acid system and is then immersed into an inorg. alkaline soln., such as aq. caustic soda soln. to penetrate the inorg. alkali into the sand core prototype. This sand core prototype is dried at a prescribed temp. As a result, the collapsibility after coasting is improved without the failure and crack of the sand core and without the infiltration of a molten metal into the sand core at the time of casting the molten metal under a low pressure.

Title: Pulse transformer driving circuit for burst signal transmission
Inventor: KAWATOKO TSURAYUKI
IPC: H04L25/02
Filed: 1985-05-23
Abstract: PURPOSE:To reduce number of parts by connecting the emitter of a transistor to the middle point of the primary winding of a pulse transformer and preventing magnetic saturation by letting flow current of reverse direction and the same quantity in the primary winding by a select signal. CONSTITUTION:When a burst signal 11 drives the primary winding of a pulse transformer 40, voltage at the middle point P of the primary winding becomes common voltage of an output differential amplifier circuit 10. On the other hand, a select signal 14 becomes logical low voltage, and emitter voltage of a transistor TR 20 is made to become lower than voltage of the middle point P. When the signal 11 is terminated, one of output 12, 13 of the emitter output differential amplifier circuit 10 becomes logical high level and another becomes logical low level. At this time, the signal 14 becomes logical high voltage. It is determined to make emitter voltage of the TR 20 higher than logical high level of output 12, 13. Thus, the circuit 10 becomes off, and current is shunted from the TR 20 to the primary winding, and accordingly, magnetic saturation is not caused.
