CONSTITUTION:The image data are received from a signal line 500 and an aimed picture element and its nearby picture elements are held in latches 502-504, and 507-512. A CPU 519 detects a horizontal and a vertical picture element array vector according to the state of the aimed picture element and its nearby picture elements and discriminates and stores the mutual connection states of those picture element array vectors in a connection information table on a memory 520. An aimed raster on which all picture elements are white picture elements is detected and when it is detected, the stored connection information table is scanned to extract contour points, and then cleared. The aimed picture element is taken out in the order of raster scanning and the processing is repeated to perform processing covering all object image data.

Inventor: SHIMURA SHU
IPC: B60T17/02
Filed: 1999-01-21
Abstract: PROBLEM TO BE SOLVED: To improve a pump device including a plurality of hydraulic pressure pumps. SOLUTION: In the upstream of a check valve 45 on the discharge port side of a high pressure pump 42, a relief valve 48 is provided. When discharge pressure of the high pressure pump 42 becomes higher than opening valve pressure, excessive discharge pressure of the high pressure pump 42 can be avoided and excessive load applied to a pump device 30 can be avoided, because hydraulic fluid s returned to a reservoir 53 via the relief valve 48. Even if the relief valve 48 becomes recovery impossible due to biting of foreign matter, hydraulic fluid discharged from a low pressure pump 42 is not returned to the reservoir 53 via the relief valve 48 by the check valve 45. Therefore, supply impossible of hydraulic fluid of sufficient fluid pressure from the pump device 30 can be avoided.

Title: Pulse train signal generating circuit
Inventor: KAWASHIMA TETSUYUKI
IPC: H03K3/72
Filed: 1986-01-24
Abstract: PURPOSE:To improve the accuracy of digital control by counting the 2nd clock pulse which are not frequency-divided by the 2nd counter until the output of the 1st counter coincides with a digital control signal and inputting the output signal of the 2nd counter to a rate multiplier instead of the digital control signal. CONSTITUTION:The 2nd counter 27 counts the 2nd clock pulses repeatedly every time a coincidence detection signal is inputted to the 2nd counter control circuit 26 from a comparator 25. Therefore, its output is N times as large as a digital control signal outputted from a digital setter 11. The rate multiplier 13 converts the frequency of the 1st clock pulses to generate and output a pulse train signal of frequency reduce in proportion to the 2nd counter output signal. At this time, the signal from the 2nd counter 27 is N times as large as the digital control signal, so the frequency of said pulse train signal is high correspondingly. This pulse train signal of high frequency is frequency-divided by a frequency divider 14 to a proper value and then inputted as a digital control signal to a digital control circuit 5.
