Abstract: PURPOSE:To shorten image processing time by using an inhibiting circuit which designates a place to be masked, a mask circuit connected to the output of the inhibiting circuit, an output bit counter, and a selector which connects the outputs of said mask circuit and bit counter to an image processor. CONSTITUTION:When the image information of an image input device 11 is supplied to an inhibiting circuit 12, a place to be masked is designated by an inhibiting pattern 13 and an AND. A mask circuit 14 secures an exclusive OR between the output of the circuit 12 and a mask pattern 16. A mask can be applied to a specific bit only with combination of both patterns 13 and 16. Then a counter 17 counts the number of '1' contained in the output of the circuit 14 to decide the resemblance between the pattern 16 and an input picture and produces a mask pattern having no directivity. A selector 18 selects the information on the circuit 14 and the counter 17 to supply them to an ALU 20. Then the value of the counter 17 is compared with a constant or the output of the circuit 14 undergoes the logical arithmetic. In such a way, the images can be quickly processed.

IPC: G09G5/22
Filed: 1997-10-17
Abstract: PROBLEM TO BE SOLVED: To enhance decoding efficiency and also to clean reproduce characters without increasing a memory capacity so much even when sizes of a character font become plural by using information of the bit map font of the same character which are already decoded and which have small numbers of dots as reference pixels of bits to be decoded to reduce data amount to be handled.

Abstract: PURPOSE:To obtain the prescribed restoring force when the position of an actuator gets close to its target position and to improve the positioning accuracy of the actuator by defining the value between central values as the control target value in addition to the central value between partial sections respectively and performing the control so that the coincidence is secured between the control position of the actuator shown by the central value between partial sections and the target position. CONSTITUTION:The target positions of a motor (actuator) 1 moving within a section A divided into plural continuous partial sections A0, A1... are set at the middles (0.5), (1.5)... between the central values 0, 1... of the sections A0, A1.... Then the moving section A of the motor 1 is fractionated by means of a rotary plate 2 and a fixed plate 3 of an incremental rotary encoder E and those sections A0, A1... are discretely detected through rotations of a rotary position 2. Based on this detection, the control is performed so that the coincidence is obtained between the position of the motor 1 and the control target value. Thus the prescribed restoring force is secured even when the motor 1 gets close to its target position. As a result, the positioning accuracy of the motor 1 is improved.

Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To prevent a person from being locked up in a car by providing a control device that allows recovery of a building-side main switch from the inside of the car of an elevator, when the building-side main switch connected with the elevator and other apparatuses actuates. SOLUTION: When capacity of a main switch in a building becomes excess and the main switch trips after an elevator receives a user and starts, the trip of the main switch on the building side causes the operation of a service- interruption detecting device 7 in a control disk 5 in the elevator. The user shut up in a car operates an in-car operating switch 6 installed in the car. Operations of the in-car operating switch 6 and the service-interruption detecting device 7 actuate a switch reset output device 8. The operation of the switch reset output device 8 actuates a switch reset device 9 installed in the main switch on the building side to reset the tripped main switch to supply power to each apparatus. The elevator operates and the shut up person can be rescued.
