Title: Hanger rotating speed changing device in conveyor with rotating hanger
Inventor: TAKEDA SHUNZO
IPC: B65G47/52
Filed: 1988-12-26
Abstract: PURPOSE:To obtain smooth conveying work without suspension by engaging a large diameter sprocket, which is engaged with a second conveyor chain for rotating a hanger, with a subconveyor at a connecting point and transferring the sprocket until a small diameter sprocket is engaged with a first conveyor chain. CONSTITUTION:In, for example, a bonding oven, a large diameter sprocket 5 is engaged with a second conveyor chain 7' for rotating a hanger, so that the hanger is conveyed while it is rotated at a low speed. When the hanger reaches a connecting point D, the large diameter sprocket 5 is engaged with the chain of a subconveyor 25, so that the hanger is successively conveyed while it is rotated. When a small diameter sprocket 4 which is situated concentric with the large diameter sprocket 5, reaches the position at which it is engaged with a first conveyor chain 7 for rotating the hanger, the subconveyor 25 goes upward, and the small sprocket 4 is engaged with the second chain 7, so that the hanger is conveyed while it is rotated at a high speed. With this contrivance, the hanger can be smoothly conveyed without suspension.

Filed: 1989-12-16
Abstract: PURPOSE:To prevent the use of data based on an erroneous address signal by setting write data into a memory part, which corresponds to an address signal to be invalid or prohibiting the writing of data into the memory part when an error occurs in the address signal. CONSTITUTION:When the error occurs in the address signal 200 inputted to a cache memory device 101 owing to noise at the time of writing data from a main memory 102 into a cache memory device 101, an error detector 1 detects the error. Then, a data invalidation circuit 2 operates by receiving the error signal 4 of the error detector 1 and a valid bit corresponding to a data memory 206, which a decoding signal 214 obtained by decoding the entry address 203 of the inputted address signal in a decoder 213 shows, is invalidated. Thus, erroneous data is prevented from existing in the cache memory device 101 as valid data.

Filed: 1994-12-28
Abstract: PURPOSE: To accurately measure molten metal quantity in a short time by quietly extending a hold-up cylinder unit at the time point of the lapse of a prescribed time from starting molten metal tapping to hold up a ladle and starting weighing with a load cell from this point of time. CONSTITUTION: Large shock to the ladle 2 occurs at the initial stage of the molten metal tapping. After the lapse of a prescribed time, when the large shock stops, the hold-up cylinder unit 20 is quietly extended to hold up the ladle 2 with a hold-up part 20a.

Then, at this time, the dropping quantity of molten metal is little and the fluctuation range of the indication of the load cell is small and the error is small. Further, the shock caused by dropping molten metal is absorbed with a shock absorbing member 22 and the fluctuation range of indication of the load cell is restrained to be further smaller. At the point of time when the quantity of tapped molten metal reaches a prescribed value, a stopper member is operated through control mechanism to close the tapping hole.

Title: Magnetic powder with improved dispersibility
Inventor: NAKADA KAZUO
IPC: C01G49/00
Filed: 1987-12-25
Abstract: PURPOSE:To obtain the magnetic powder having improved dispersibility by a method wherein at least a kind of the hydroxide of Cu, Ag, Al, Sn, Nb, Ta, Sb, Cr and Ni is contained in the surface of the title magnetic powder. CONSTITUTION:The quantity of the hydroxide contained in the surface of magnetic powder is generally 0.01-20 pts. wt. against the magnetic powder of 100 pts. wt., desirably 0.05-5 pts. wt. When the quantity of hydroxide exceeds 20 pts. wt., magnetic flocculation is hardly generated, and it is effective in the improvement of dispersibility. However, as the hydroxide is a non-magnetic substance and the magnetic characteristics such as coercive force and the like of magnetic powder are deteriorated, the use of the hydroxide in excess of 20 pts. wt. is not desirable. The viscosity of the magnetic coating material, in which said magnetic powder is used, is low when compared with the case where the magnetic powder containing no metal hydroxide. From the above- mentioned fact, it can be realized that said magnetic powder has the improved dispersibility in organic binder.
