Title: Control device of hydraulic construction machinery
Inventor: NISHIDA TOSHIAKI
IPC: E02F9/24
Filed: 1997-05-14
Abstract: PROBLEM TO BE SOLVED: To provide a control device of a hydraulic construction machine which is excellent in safety and can prevent a hydraulic actuator from running uncontrolled even if a control solenoid valve installed in the pilot line of a hydraulic device gets seized. SOLUTION: A pilot hydraulic pressure p in a detecting pilot line T6 connected to the downstream of electromagnetic proportional reducing valves 13a or 13c is detected using a pressure detector 11, and the rotating angles α, β, and γ of the bent part of a working machine are detected by angle sensors 16a to 16c. For example, when the pilot hydraulic pressure p is high after a specified operational delay time from the time when the driving current of the electromagnetic proportional reducing valve 13b is reduced to zero by releasing pressing a opeartion of a switch 10a, and the rotating angles α, β, and γvary with time, a control device 9 judges that the operation of the electromagnetic proportional reducing valve 13b is faulty and outputs a drive current to close an electromagnetic switchover valve 14.

Abstract: PURPOSE:To shorten the switching time of a reception frequency by providing two independent local oscillators whose frequency changes according to the synthesizer system in a reception system circuit of a mobile body side and using a switching means to select the output of the two local oscillators. CONSTITUTION:Three switches provided in a switching circuit 30 are controlled so as to select contacts A1, A2, A3 for a transmission timing period T and a reception timing period R.

Moreover, a 1st local oscillator 17 is scanned to a frequency to receive the radio wave of an adjacent base station for the timing period of the transmission and reception. In the entrance to the reception mode of the time slot I, the switching circuit 30 is switched. Thus, even when the scan speed of the local oscillator is not high, the switching of an intercept monitoring timing reporting its own position is quickened.

Abstract: PURPOSE:To surely mesh gears with each other through change-over of gears in a short time. CONSTITUTION:When a rotational speed is selected for a spindle 7 by means of a selecting switch in order to carry out change-over from a low speed gear 12a into a high speed gear 12b, a change-over gear assembly 12 on rotation at a low speed shifts to a high speed intermediate gear 11b of a main gear 11, and accordingly, crests of the teeth of the high speed gear 12b in the change- over gear assembly 12 on rotation at a low speed can always align with troughs of the teeth of the high speed intermediate gear 11b on rest so that they can be meshed with each other. Accordingly, only by selecting a rotational speed with the use of the selecting switch, the change-over of the change-over gear assembly 12 can be surely and promptly made, and further, even during drilling, the speed can be changed over without depressing a switch button so as to stop a motor 5.

Abstract: PROBLEM TO BE SOLVED: To execute a picture area separation processing with high precision by comparing the count value of a group number counting means and a prescribed threshold value and deciding whether an extracted area is a character area or the halftone one. SOLUTION: A black picture element total number counter 201 counts the total number of black picture elements in a reference area and outputs it to the first to fifth decision parts 208-212 in a picture separation processing part 200.

A vertical direction change point counter 203 counts the number of change points in a vertical direction in the reference area and a horizontal direction change point counter 204 counts that in a horizontal direction. The probability of the halftone area is high if there are many change points and that of the character area is high if not many. One of the respective decision parts 208-212 is operated depending on the total number of the inputted black picture elements. Besides, respectively different threshold values are set and each executes the threshold value decision for the plural inputted count values. Therefore, area deciding precision is enhanced.
