Abstract: PURPOSE: To obtain a harmonic suppressor for a distribution system in which even a severe harmonic can be suppressed stably without causing overloading. CONSTITUTION: One winding of a matching transformer 5 and an LC filter 7 are connected in series with a distribution system and the other winding of the matching transformer 5 is connected with a stationary power converter 6 to constitute a voltage absorbing active filter 4. The active filters 4 are distributed for the distribution line thus constituting a harmonic suppressor. A system for detecting the voltage of the distribution system and controlling the stationary power converter to have a sine wave voltage is provided with a sine wave command and the current of the active filter 4 is detected and controlled by a comparison circuit receiving the controlled voltage and a current limit set value.  A multiplier multiplies the controlled voltage output by an output from the comparison circuit and a current command is held at a predetermined level on condition that the controlled voltage output exceeded a predetermined current limit value. Harmonics of the distribution system are absorbed while suppressing the filter current below the predetermined level.

Title: Image processor
Inventor: SAKANO YUKIO
IPC: G06T1/00
Filed: 1987-12-08
Abstract: PURPOSE:To prevent a mark itself from appearing as an image in a copy when a trimming/masking is executed by making a mark area except the mark itself into a trimming area at the time of the trimming and making the mark area including the mark itself into a masking area at the time of the masking. CONSTITUTION:The title device has a mark detecting circuit 1, a mark area detecting circuit 2, an inverter 3, an AND gate 4 and a selector 5. A mark erasing control signal (h) is a signal to control whether the mask itself is included in the mark area or not regardless of the trimming/masking and interlocks with a selecting switch in an operation part. When h='H', a control not including the mark itself is executed and when h='L', the mark itself is included in the mark area regardless of the trimming/masking. Consequently, when the signal (h) is made high-level by the selecting switch of the operation part, the mark area except the mark itself can be made into the trimming area. Thus, the mark can be prevented from appearing as the image in the copy at the time of the trimming/masking.
