摘要： Only snapshot data necessary for monitoring faults are collected from machine such as vehicles, allowing faults to be more accurately monitored, and the amount of data and the memory storage volume at a monitoring station to be reduced. The values of a plurality of (A), (B), (C), and (D) operating parameters (engine rotational speed, lever operating position, vehicle speed, and tractive force) which change during the operation of the machine are sequentially detected for each machine. The fault detection history data are thus updated every time a fault (drop in engine oil pressure, overheating) is detected during the operation of the machine. Thus, when a fault (drop in engine oil pressure) is detected during the operation of the machine, it is determined on the basis of the history data whether or not to send to the monitoring station the sequential values of the operating parameters ((A) engine rotational speed, (B) lever operating position, (C) vehicle speed, (D) tractive force) from within a prescribed period of time (from 10 min. before to 5 min. after) around the point in time t0 at which the fault was detected. When it is determined that they should be sent, the type of detected fault (0001 (drop in engine oil pressure)), the values detected ((A) 2, (B) 3, (C) 3, (D) 2) at the time the fault was detected, as well as the sequential values of the operating parameters from within a prescribed period of time (from 10 min. before to 5 min. after) around the time the fault was detected are transmitted to the monitoring station. When it is determined that they should not be sent, on the other hand, the type of detected fault (0001 (drop in engine oil pressure)) and the values detected ((A) 2, (B) 3, (C) 3, (D) 2) at the time the fault was detected are sent to the monitoring station.

摘要： A dozing system for a bulldozer capable of providing high operational efficiency in dozing operation and a smooth excavation face. If it is determined when operation is performed in an automatic digging mode that the load exerted on the blade is stable, a target position for the cutting edge relative to the ground is corrected to the actual position of the cutting edge at that time. According to the ratio of the amount of excavated soil loaded on the front surface of the blade to the loading capacity of the blade front surface and/or the stability of the load exerted on the blade, a switching is performed between a weight characteristic for the operation amount of the load control and a weight characteristic for the operation amount of the smoothing control. Further, a map for correlating actual travel distance with the position of the blade cutting edge is prepared, and stable cutting edge positions are accumulated in each respective cycle and averaged to obtain an optimum target value for the smoothing control.

摘要： A film applying apparatus is provided with preparatory bonding rolls, laminating rolls, a laminated film wound out from a film roll and a substrate conveyed by a substrate conveying device. The laminated film passes between these rolls and pressure bonding is performed. The diameter of the preparatory bonding rolls is made smaller than the diameter of the laminating rolls. The range of the elastically deformed area at the roll surface where the grasping of the substrate and the laminated film by the preparatory bonding rolls is begun, is made small, thereby limiting the range and reducing the generated amount of air holding or the like.

摘要： An improved accuracy is ensured for the calculation of the travel distance of a bulldozer by obtaining the accurate vehicle speed and travel direction of the bulldozer. To this end, arrangement is made such that a check is made to determine whether actual tractive force F exerted on the blade exceeds a predetermined shoe slip threshold value F.sub.0 ; switching between vehicle speed detectors (between a Doppler sensor and Sprocket rotating speed detector) is made according to the determination so that suitable one of the vehicle speed detectors detects the vehicle speed of the bulldozer; and the vehicle speed detected by the selected vehicle speed detector is integrated, whereby the travel distance of the bulldozer is calculated.

摘要： A tractive force control apparatus and method for preventing a torque converter from being stalled while a working machine is operated during excavation and earth carrying work using a construction machine. In this apparatus, an engine rotational speed sensor (2), a torque converter output shaft rotational speed sensor (4) and a lift combination solenoid valve (12) are connected to a control apparatus. A pilot pressure control valve (11) for a blade lift is connected to a first lift operating valve (13), and also to a second lift operating valve (14) via the lift combination solenoid valve (12). First and second hydraulic pumps (20, 21) and lift cylinders (15, 15) are connected respectively via the first and second lift operating valves (13, 14). A traction output is computed in the control apparatus (16), and, when the traction output is lower than a target level, the lift combination solenoid valve (12) is turned off to reduce a flow rate of oil to the lift cylinders (15, 15). The traction force is thus increased correspondingly to prevent a torque converter (3) from being stalled.

摘要： In a light control element whose reflection factor or transmission factor varies in response to an external stimulus such as voltage by having layer structure in which the refractive index varies periodically, design is made such that the difference in refractive index between adjacent layers in a reflected state becomes sufficiently great and the half-amplitude level of reflection spectrum becomes sufficiently high. A light control layer is interposed between supporting plates, and the light control layer is obtained by alternately laminating a nonsensitive layer and a sensitive layer in the Z-axis direction.In the nonsensitive layer, the oriented direction of the liquid crystal is fixed in the X-axis direction, while in the sensitive layer, the liquid crystal is oriented in the X-axis direction. On the supporting plate, a pair of electrodes and facing to each other in the Y-direction are so formed as to extend in a striped shape in the X-axis direction respectively. When voltage is applied between electrodes, the oriented direction of the liquid crystal in the sensitive layer changes into the Y-axis direction.
