Title: Movable beam projecting device
Inventor: KONDO TAKAHIKO
IPC: G02B26/08
Filed: 1988-09-27
Abstract: PURPOSE:To secure a relatively wide beam irradiatable extent even when the movement of mobile arms is restricted by fitting at least one of beam direction changing elements to a prescribed position of the mobile hollow arm mechanisms through an actuator having a specific degree of freedom. CONSTITUTION:Spatial relations between beam direction changing elements m1-m9 and their fitting positions are changed by means of actuators so that the direction of a beam can be changed. In other words, when the elements m1-m9 are driven by means of the actuators, geometrical relations between mobile hollow arm mechanisms AM1-AM5 and the beam direction changing elements m1-m9 are changed. As a result, the source of a beam LB, the direction of which is changed by the elements m1-m9, changes and the irradiating position and/or irradiating direction of the beam LB to an object to be irradiated with the beam LB changes. Therefore, the irradiatable extent of the beam LB can be secured relatively widely even when movement of their own mechanisms AM1-AM5 is restricted.

Title: Polling method
Inventor: SUZUKI MUNEYUKI
IPC: H04L12/40
Filed: 1988-09-28
Abstract: PURPOSE:To efficiently specify an interruption request generating source in a short time even when a large number of parts exist by performing polling according to a first procedure to specify a group and a second procedure to specify an interruption request generating means in the group. CONSTITUTION:Two thousand and forty eight terminal interface parts (IF parts)3(30001-32048) are provided, and also, those IF parts are divided into 16 groups of every 128 parts, and are connected commonly to each bus line distributed and relayed by 16 distribution units 6 (601-616) at every group unit. In other words, each unit 6 unifies the IF parts 3 in respective group. When information representing the generation of an interruption request is received, a control part 100 performs the polling to each unit 6 first, and specifies the group in which the interruption request generating source is included. Next, by performing the polling to the IF part 3 included in a specified group, a corresponding interruption request generating source can be specified. In such a way, it is enough to comsume a time required for the polling in [number of groups+(number of IF parts per one group)X(cycle time per one polling)], thereby, the time can be remarkably reduced.
