Title: Casting method
Inventor: YOSHIOKA HIDEHO
IPC: B22C9/04
Filed: 1989-01-31
Abstract: PURPOSE:To prevent the development of casting defect and oxidized decarbonization by causing non-oxidized gas to flow into gas flowing hole formed in a backup part at the time of casting in a ceramic mold constituted of the ceramic part and the backup part, and casting molten metal. CONSTITUTION:At the time of causing the non-oxidizing gas of inert gas, etc., to flow as cooling gas into gas flowing hole 4 in the backup part 1 at the time of the casting, the gas flows toward the desired surface of a product to be cast through the molding material between the sands, etc., in the backup part. In this result, the mold around cavity 3 in the product part is cooled and the heat of the molten metal in the product part is sufficiently absorbed to the mold. Therefore, directional solidification from the product part is quickly progressed and feeder head part comes to the last solidified part and the product comes to a precise casting having excellent dimensional accuracy with any casting defect. Further, by limiting the gas to the non-oxidized gas, the development of oxidized-decarbonization in the casting surface is eliminated and the casting having excellent casting surface characteristic can be manufactured.

Title: Air fuel ratio controller
Inventor: TAKADA SHIGETAKA
IPC: F02D33/00
Filed: 1980-02-20
Abstract: PURPOSE: To prevent a wide range of reduction of a running performance and the fuel economization by determining whether the control is being performed regularly or not from the number of reversals of the output from an exhaust gas sensor in order to stop the air fuel ratio control depending upon the output of the exhaust gas sensor when the control is in an irregular condition.  
     CONSTITUTION: If a trouble occurs at a part of a control system, such as at an O 2  sensor 6, and hence the control is brought out of a regular condition so that the air fuel ratio is widely displaced from an aimed air fuel ratio, the number of clock signals per unit time to a counter 904 for counting the output of the O 2  sensor 6 which repetitively presents changes little by little between rich and lean is reduced. Accordingly, the count advances a very little, and when the output C of an AND gate 921 is L and the temperature of water is high so that the output of a water temperature detector 902 is L, the output FF of a flip-flop in a trouble detecting circuit 930 becomes H to thus detect the trouble. An actuator 8 serving as an air fuel ratio adjusting means is thereupon moved and fixed to a predetermined position through a holding circuit 950 to thus maintain in a good condition the running upon appearance of a trouble.
