Title: Dimming device
Inventor: KAGEYAMA MOTOHIRO
IPC: H05B39/08
Filed: 1991-05-13
Abstract: PURPOSE:To provide a dimming device capable of preventing a phase control element from being influenced by a large current at the time of short-circuiting as well as having no trip due to rush current. CONSTITUTION:A phase control element 13 is phase-controlled according to a trigger signal from a control circuit 16, and a current supplied to an illumination load 12 such as an incandescent lamp from an A/C power source 11. When an excessive current at the time of load short-circuiting, it is detected by a detection circuit 18, and an optical signal P1 from a LED 24 is given to the control circuit 16. Since the circuit 16 stops the leading-out of the trigger signal in response to the optical signal P1, the element is to have no continuity from the time point of the next semi-cycle of the AC power source 11. With the maximum allowable current value being set larger than the rush current of illumination load 12, a dimmer device does not function with the rush current, and also the phase control element 13 can be protected enough.

Title: Controlling and processing system for unreadable character image
Inventor: TACHIBANA KOJI
IPC: G06K9/03
Filed: 1987-04-30
Abstract: PURPOSE:To lighten the processing load on an application program and to utilize an image working area effectively by controlling the image of a character field where there is an unreadable character by using indexes that a system adds automatically. CONSTITUTION:If a character field contains an unreadable character, a read error decision part 15 detects it and an image read part 16 reads the character field as an image automatically. The read image is stored in the image working area 22 by an image control part 17 and its index information is reported to the application program 10. Then the application program 10 uses the indexes to only indicate display operation, so that the image is displayed on a display 21. Consequently, the processing load on the application program 10 is reduced greatly and the image working area 22 is utilized effectively.

Filed: 1999-04-16
Abstract: PROBLEM TO BE SOLVED: To eliminate adhesion of paper powder or the like and surely operate a punch even in case of use for a long term by restraining generation of negative pressure accompanying motion of a motion system containing a drive means. SOLUTION: Suppression of generation of negative pressure is attained by relaxing the degree of airtightness between a space generating negative pressure such as a closed space formed out of an exciting coil, and a core and a movable core in the exciting coil and opposite to each other, and the open air. A punch unit is provided with a vent 10 communicated from a closed space surrounded with the exciting coil and between the opposed parts of the core 2 and the movable core 5 to the outside, to prevent excessive negative pressure from generating. Hereby, even if a little negative pressure is generated, the negative pressure is propagated to a punching local part to suck paper powder or the like, and the punch is not uncertainly operated. Consequently, even in the case of use for a long term, operation of the punch can be made sure.
