Title: Fuel tank opening and closing device for motorcycle
Inventor: HARA IKUO
IPC: B60K/
Filed: 1992-10-30
Abstract: PURPOSE:To facilitate a release work and closing operation by a method wherein after a fuel tank rear part support mechanism is moved rearward and a front lock tool is unlocked, a fuel tank is rocked upward around a rear part serving as a fulcrum to effect release and a portion above an engine is released. CONSTITUTION:The bolt 50 of the rear part support mechanism 30 of a fuel tank 13 is unscrewed and a bracket 44 is moved rearward between a press plate 33 and a press plate 37. The rearward movement of the bracket causes dislocation of a hook member at the front part of the fuel tank 13 from a roller on the frame side. In this case, backward movement of the bracket 44 is regulated by a rise piece 35 and the mounting hole 47 of a bottom hole 46 is matched with the mounting holes 40 and 41 of the press plate 36 and the support plate 33. In which case, the bolt 50 is inserted in the mounting holes 47, 40, and 41 and the fuel tank 13 is maintained in backward movement position. The fuel tank 13 is then rocked upward around a pin 48 serving as a fulcrum and held in a release state by a tilt-up cylinder and a portion above an engine is released. closing operation is reversed.

Title: Refining device for molten aluminum
Inventor: MAEDA HIDEO
IPC: C22B9/02
Filed: 1991-11-29
Abstract: PURPOSE:To enable the efficient sepn. of high-purity Al at a low cost by disposing a rotating magnetic field generating coil by a specific angle in the side wall part on the outer side of a container and constituting the container in such a manner that the drum can be tilted without being affected by the coil. CONSTITUTION:The rotating magnetic field generating coil 7 is disposed in the side wall part of the container existing at 90 to 180 deg. angle from the center of the container in the container 2 for holding the raw material molten A1. A current is passed to the raw material molten A1 in the container 2 to rotate the Al. The impurity Al thickened between the dendrites grown on progression of solidification is sufficiently diffused to the Al liquid phase part of the remaining remote part by rotating the Al, by which the deviation of the impurity concn. in the liquid phase is decreased and the Al having the high purity is crystallized. Since the disconnection of the container 2 and the coil 7 is easy, the remaining molten A1 is rapidly discharged and the high-purity Al is efficiently separated at the low cost.

Filed: 1989-12-07
Abstract: PURPOSE:To shorten the rise time of a memory device by performing the write, the read and the comparison of the test data automatically and in sequence with use of hardware. CONSTITUTION:The data 0 on a diagnostic address register 2 is stored in an address 0 of a memory 1 as the input data S4.

In a read state the address data written in a write state are read out of the memory 1 in the same timing as the read data. Then the comparison is performed via a comparison coincidence circuit 10 between the output data S6 on the memory 1 and the output data S4 on the register 2. When no coincidence is obtained between both data, a memory abnormality signal S11 is transmitted to a diagnosing device via an abnormality display register 12. Thus the memory 1 can be automatically diagnosed with no interven tion of the diagnosing device. Then a diagnostic program is simplified and the rise time of the memory 1 is shortened.
