Then the molded body is heated to a temperature between about 850 deg.C and about 1,050 deg.C in a vacuum of about 1×100 to 9×10-6 Torr and is successively sintered, heat-treated, and surface-treated. The heat treatment in the vacuum is performed, in such a way that the molded body is subjected to a first-stage vacuum heat treatment in which the molded body is heated to about 550-650 deg.C in a vacuum of about 1×100 to about 9×10-6 Torr.  Then the body is subjected to a second-stage vacuum heat treatment in which the molded body is heated to about 850-1,050 deg.C in the vacuum of about 1×100 to 9×10-6 Torr. Therefore, the quantity of oxygen contained in the molded body can be reduced by accelerating decalcification.

Title: Device for indicating direction of tire of vehicle
Inventor: KASHIWAKURA EIJI
IPC: B62D15/02
Filed: 1982-04-01
Abstract: PURPOSE:To prevent wrong operation at starting, by recognizing with eyes how much the direction of a tire is shifted. CONSTITUTION:A pendulum 9 always moves vertically downwards due to its weight in response to the turning of a steering wheel 1. At that time, a difference is made between the pendulum 9 and a gear 5 secured on a case 3 fixed on the steering wheel 1 and a transmission gear 6 pivotally coupled to the pendulum is rotated in an apparently fixed position while being engaged with the secured gear 5. Since a pointer gear 11 on a pointer shaft 10 is engaged with the small-diameter teeth 6b of the transmission gear 6, the pointer gear is rotated at a reduced speed so that a pointer 7 mounted on the pointer shaft 10 at the opposite part to the pointer gear is displaced on the direction graduations of a dial 12 at a speed which is appropriately reduced to turn the pointer in the same direction as the steering wheel 1 to indicate the direction angle of a tire.

Title: Alarm mutual mask system
Inventor: MITSUNAGA EIJI
IPC: H04Q9/00
Filed: 1989-03-07
Abstract: PURPOSE:To allow the operator to attain alarm mask setting/release simply at a field by sending a mask bit representing a bit desired to be masked from the field together with a status change data to a processing unit 30. CONSTITUTION:The operator generates a mask bit corresponding to (belonging to) a device being an object of supervision in the operation of the device. The mask bit is sent to a monitor information collection device from a monitor object installation together with monitor information and sent further to a processing unit 30 as a state change data. The processing unit 30 references an alarm mutual mask table 35 and does not use the mask bit for output edit processing when the bit is sent from the monitor information collection device when the mask bit of the data exists in the said table 35. Thus, the transmission and display of the alarm caused in the job to a monitor terminal equipment are not implemented and the mask processing is automated.

Filed: 1979-05-04
Abstract: PURPOSE: To obtain the mold of high strength and high accuracy by adjoining a squeeze plate provided with a membrane at its bottom to the top surface of the molding sand packed in the mold-forming cavity, letting the membrane expand and pressing the squeeze plate in that state.  
     CONSTITUTION: A mold-forming cavity 5 is formed by the surface of the pattern device consisting of a pattern 2 and a pattern plate 3 and the internal surface of the molding flask 4 placed on the plate 3. A build-up flask 6 is placed on the flask 4 and molding sand S is packed in the cavity 5, after which a squeeze plate 7 provided with an expansion membrane 9 is hermetically lowered in the build-up flask 6, so that the bottom surface of the plate 7 is approached to the top surface of the molding sand 6. Where both contact or assume a slight distance, a valve 11 is opened to feed high-pressure air to the inner side of the membrane 9 and let the membrane 9 expand instantaneously. This causes the molding sand S to receive impulsive pressing force and be pushed to the surface side of the pattern device. The valve 11 is reclosed to confine the high-pressure air in the membrane 9, in which state the plate 7 is further lowered.
