Abstract: PURPOSE:To judge in which graphic a hole is contained by providing two sets of one path method devices, and constituting them so that one device can receive a binary image signal by a one-picture element portion earlier than the other device. CONSTITUTION:The device is constituted so that a second one-path method device 2 executes a scan by a one-picture element portion earlier than a first one-path method device 1, that is, receives a binary image signal earlier by a one-picture element portion.

Title: Printed board cad system
Inventor: INOUE KAZUO
IPC: G06F17/50
Filed: 1989-10-31
Abstract: PURPOSE:To reduce the using capacity of a memory and to attain rapid reverse processing by discriminating an area to be plotted as a pattern from an area not to be plotted as a pattern on a printed board. CONSTITUTION:The CAD system is provided with an outline vector approximate processing module 2, a graphic synthesizing processing module 3 and a rotating direction deciding processing module 4. A wiring pattern on a reversely designed board is approximated by a counterclockwise outline vector and individual pattern graphics are synthesized to find out the outline vector of the synthesized graphic. Then the graphics of all the wiring patterns are synthesized and the rotational directions of outline vectors of all the synthesized graphics are decided. Since the outline vector of a reversely designed pattern is defined as the counterclockwise direction, it is decided that a graphic whose outline vector is clockwise direction is drawn as a pattern on the printed board in the case of reverse processing. Consequently, the using capacity of the memory can be reduced and the reverse processing can rapidly be executed.

Abstract: PURPOSE:To simply inspect a printed circuit board and to correct reference data when a measuring condition is changed by comparing the impedance measuring data of a production lot board with reference data. CONSTITUTION:Measuring AC voltage is applied to a plurality of good product printed circuit boards 12' from a signal source 11 and the current flowing to the same measuring point of the same pattern of each board 12' is measured by a measuring part 13. The impedance at said measuring point is calculated from said current by an operation means 14 to calculate the mean value thereof and the threshold value of the standard deviation of the irregularity of impedance to the mean value is calculated. Then, the mean value and the threshold deviation are respectively set as the comparing reference value of impedance and the tolerance of irregularity by a reference value setting means 16 and a tolerant difference setting means 17. In the same way as the above mentioned case of a good product board 12, impedance is calculated from the printed circuit board 12 to be inspected of a production lot to be compared with the reference value by a comparing means 15 and the quality of the board 12 is judged based on whether impedance is within the tolerance.

Title: Toner concentration controller for image forming device
Inventor: SHIBATA KIYOTAKA
IPC: G03G15/08
Filed: 1988-11-08
Abstract: PURPOSE:To surely prevent a photosensitive drum from being damaged by allowing a toner exhaustion absolute display means to operate a toner exhaustion display means in spite of limits by a toner exhaustion message control means in the case an output value lowers. CONSTITUTION:A toner sensor detects the concentration of toner in a developing part owing to a change in inductance, and outputs the concentration as a change in a voltage. A temperature sensor detects temperature near the developing part. When a value outputted from the toner sensor lowers to the extent which such judgement is made that the entire toner for replenishment is consumed regardless of the temperature detected by the temperature sensor, the toner exhaustion absolute display means operates the toner exhaustion display means in spite of limits by a toner exhaustion message limiting means. Consequently, the photosensitive drum can be surely prevented from being damaged by a considerable decrease in picture density, carrier attraction, etc.
