Title: Method for detecting molten metal level in casting mold
Inventor: TENMA MASAMI
IPC: G01F23/00
Filed: 1989-03-31
Abstract: PURPOSE:To prevent detection delay from being generated by finding the detection gains of a thermally sensitive element in the rising and falling processes of the molten metal surface level in the casting mold previously from facility conditions and operation conditions and setting the temperature correction coefficients of the respective processes. CONSTITUTION:Thermocouples 9 are embedded in the casting mold 5 at specific intervals and the temperature detected values of the thermocouples 9 are inputted to a level computing element 11. The computing element 11 finds the maximum value of temperature from a temperature pattern found based upon the temperature detected values, searches for a temperature value coincident with the value obtained by multiplying the maximum value by a predetermined correction coefficient from above the casting mold 5, and calculates the position where the temperature is coincident to detect the molten metal level 6. The best correction coefficients of the respective processes are found by comparing the level value of a thermocouple type level meter with a level real value detected by a level meter utilizing an electromagnetic wave and varying such a correction coefficient that both the values coincide with each other. The momentary temperature detected values are corrected with the correction coefficients to detect accurate temperature corresponding to variation in the molten surface level.

Title: Bar holding grip
Inventor: MITA KAZUHIRO
IPC: F16L3/12
Filed: 1994-03-30
Abstract: PURPOSE:To prevent a bar from slipping off from the inner part of its holding part without fail by installing a foldable regulating means to regulate the widening of an antislip claw piece in an interval between a backside of this claw piece and an opposite face of the holding part, in this holding grip integrally formed with this tilting antislip claw piece in an opening edge of an insertional port of the bar holding part. CONSTITUTION:In time of holding a bar R, a grip 1 itself is clamped tight to the side of a panel P via a clamping piece part 7 and a mounting hole H, and then an inward flection of an antislip claw piece 6 is secured, through which the bar R is inserted into a holding part 2 from an inserting port 3. With this insertion, the bar R is automatically held in space between a receiving seat 4 and a tip part of the antislip claw piece 6. In the holdingness of this bar R, when a large external force in the slip-ff direction is added to the bar R, the antislip claw piece 6 is also liable to be deformed and expanded outwards, but regulative action of a regulating means 8 works, whereby any of these deforming and expanding motions in the antislip claw piece 6 are regulated in consequence, and such a fear that the bar R is slipped off from an inner part of the holding part 2 and the antislip claw piece 6 is broken from its own base side and so on is prevented from occurring in an effective manner.

Title: Grinder
Inventor: IWASAKI RYUICHI
IPC: B24B31/00
Filed: 1987-04-04
Abstract: PURPOSE:To provide good grinding surface and stabilize the amount of grinding per unit time by keeping the gap between a grinding tool and a work to be ground at the target value, wherein control for keeping the gap is conducted on the basis of dynamic pressure generated between the grinding tool and the work. CONSTITUTION:The gap  t formed between a grinding tool such as polyurethane sphere 6 and a work to be ground 18 relates to the dynamic pressure P generated in this gap as 1:1. This requires determination of the dynamic pressure P' corresponding to the target gap  t' from the relation between the dynamic pressure P and the gap t determined on a preliminary experiment. The load on the grinding tool 6 is controlled on the basis of deviation of the sensed dynamic pressure p from the dynamic pressure P'. This maintains the gap  t at all times at the target value  t' to prevent contact of the grinding tool 6 with the work 18, that provides good ground surface deterioration at layer due to processing.
