Title: Overcurrent detector of pulse-width-modulated signal amplifier circuit
Inventor: YOSHIDA TADAO
IPC: H03F1/52
Filed: 1979-01-11
Abstract: PURPOSE:To prevent a switching element from breaking down without deteriorating switching characteristics, by providing a resistor for overcurrent detection in LPF. CONSTITUTION:A sound signal from input terminal 1 is supplied to load 14 by way of pulse-width modulation circuit 3, a pulse-width-modulated signal amplifier and LPF13. Here, resistor 15 for overecurrrnt detection is provided in LPF13. Further, transistors TR17 and TR18 are transistors for detecting forward and backward overcurrents. Now, since a current flowing through resistance 15 is below a prescribed value in an adequate load state, the input signal from terminal 1 is not limited at all. However, the current through resistance exceeds the prescribed value in an overload state, and consequently either of TR17 or TR18 turns ON while TR22 and FET23 also turn ON. Therefore, the input signal is never supplied to circuit 3. Thus, switching elements 11 and 12 can be prevented from breaking down without deteriorating switching characteristics.

Title: Treating method of permanent mold
Inventor: SUGITANI JIYUNICHI
IPC: B22C9/06
Filed: 1979-01-12
Abstract: PURPOSE: To obtain the cast pipe free from any shrinkage cavity in the inside surface by coating refractory slurry on the inside surface of the preheated permanent mold and drying the same through vacuum degassing then performing pouring and casting.  
     CONSTITUTION: While the preheated permanent mold is being rotated, slurry-form refractory coat is coated thereon through a coat injection nozzle which makes reciprocating motion in the axial direction. After the film of the specified thickness is formed, the mold is put in a vacuum box and is subjected to degassing treatment for 20W60min in a vacuum of about 1W10 Torr to allow the moisture and volatile components interposing in the inside surface of the film to evaporate and desorb. This treatment makes it possible to prevent the phenomenon of producing shrinkage cavities owing to oozing of the volatile components on the inside surface of the casting when molten metal is poured into the rotary mold.
