IPC: G06F13/24
Filed: 1994-12-28
Abstract: PURPOSE: To variably set up the priority of interruption processing by semiautomatically changing the connection address of an interruption signal to a data processor body by an instruction front an instruction means. CONSTITUTION: An interface is mounted on an image forming device, a discriminator 105 recognizes the sort of the connected interface and transmits the recognized result to an operation part 107 to display the result on a display screen. While observing the display, a user sets up the priority of the interface by an input switch in the operation part 107. The set priority information is set to the discriminator 105 and the level contents of a selection signal are determined. In the case of applying priority to the interface, a selector determines a selection level so that an interruption signal generated from the interface is inputted to the INT terminal of a CPU. Consequently the user can optionally determine the priority of the interface based upon an instruction from the operation part 107.

Title: Fluid motor for introducing fluid also from side of housing
Inventor: ABE YOSHIO
IPC: F03C2/08
Filed: 1998-10-05
Abstract: PROBLEM TO BE SOLVED: To improve rotation efficiency in consideration of the following: both rotors of approximately the same shape have concave and convex portions, and collectively have such a shape that is obtained as a result of rotating in contact with each other in the reverse directions at the equal speed, and rotation force of the rotors is increased by providing a lateral fluid shunt at the position on the side of an inlet port where the lateral fluid shunt does not come into contact with both rotors even during their rotation, but a pressure in the lower portion of the lateral fluid shunt is decreased, and thus the rotor on the side of a fluid pressure does not receive a pressure at the rear surface of its convex portion, thereby degrading the rotation efficiency. SOLUTION: At a position on the side of an inlet port with respect to both rotation shafts 26, 29, an opening is formed on one side or both sides of a housing 25. A wall surrounding an inlet path is provided so as to cover the opening except for an inlet port 21, whereby a fluid is introduced also from a side of the housing. If required, a vertical fluid shunt 36 is provided approximately at the center of the opening, thereby improving rotation efficiency of the rotors.
