Abstract: PURPOSE:To increase the axial thrust by setting the thickness of a large- diameter portion in ferromagnetic core smaller than the thickness of corresponding ring-shaped yoke. CONSTITUTION:The one open end of a hollow cylinder 18 of nonmagnetic material is connected in a vacuum device, and the closed end is horizontally projected out of the device. A magnetic structure 22 is movably disposed on the outer periphery remotely from the cylinder 18, and a ferromagnetic core 20 having a drive shaft 16 is inserted into the cylinder to form an actuator. An annular groove 24 of U-shaped section is sequentially recessed on the core 20 to alternately dispose large-diameter portions 20a and small-diameter portions 20b, and a ring-shaped yoke 28 and a rare earth metal magnet 30 are alternately disposed on the structure 22. In this case, the thickness of the portion 20a is formed smaller than that of the yoke 28.

Abstract: PURPOSE: To prevent the generation of breakage of a sheet supporting plate or an elevator means for the sheet supporting plate, even if the sheet supporting plate is raised, in a sheet loading disorder state. CONSTITUTION: If a user erroneously places a sheet member S on the second sheet supporting plate 2 having no detecting means 134, and if the sheet member S on the second sheet supportlng plate 2 makes contact with other member 135, before the first sheet supporting plate 1 is detected by a detecting means 134, each load over a prescribed value acts on the second sheet supporting plate 2 and an energizing means 3 for energizing the second sheet supporting plate 2.

Title: Printing control circuit
Inventor: KAWAMATA YOSHIO
IPC: G06F12/14
Filed: 1992-09-10
Abstract: PURPOSE:To form a highly reliable protecting circuit by providing a protecting address assigning means for memory block and an address comparing means for comparing the sizes of two input addresses. CONSTITUTION:When a raster scan reading circuit performs zero clearing operation (zero writing operation) for address in a specific region, an address signal 65 becomes large as compared with an output 24. For this reason, a comparison result signal 25 becomes low and an output 26 changes the same as WE signal B 64. Therefore, the content of the address designated by the raster scan reading circuit is cleared to be zero. On the other hand, when the raster scan reading circuit performs zero clearing operation for address in a specific region, the address signal 65 becomes smaller than or the same as the output 24. For this reason, the comparison result signal 25 becomes high to protect the content of the address wrongly designated by the raster scan reading circuit from the zero clearing.
