摘要： A mobile communication system that can obtain mobile station location information repeatedly at short intervals, without depending on whether base stations are synchronous or asynchronous, with lower loads and suppressed use of radio resources. For obtaining location information, a mobile station receives a paging channel periodically sent from a base station (Step 100), obtains the contents and the reception timing of this paging channel. Further, if it is necessary to obtain the transmission timing of the paging channel, that transmission timing is obtained (Steps 105, 106). The propagation delay of the paging channel or propagation delay differences between a plurality of periodic paging channels are calculated from the transmission timing and the reception timing of the paging channel (Step 107). The mobile station location information is calculated from the propagation delay or propagation delay difference, and outputted (Steps 108, 109, 110).

摘要： A hydraulic drive system for the pitch cylinders (4A, 4B) of a bulldozer blade apparatus can include (a) main hydraulic pumps (30A, 30B) and an assistant hydraulic pump (31) to make up the assistant hydraulic circuit, (b) variable displacement hydraulic pumps (21A, 21B), or (c) fixed displacement hydraulic pumps (30A, 30B) and a plurality of solenoid selector valves such that the pitch cylinders can be connected in series. The assistant hydraulic pump (31) is connectable to delivery lines of the main hydraulic pumps through an assistant solenoid selector valve (32) which is controlled by an external signal. The blade (10) can be formed so that a line (14) tangential to the lower edge of the curved panel of the blade is inclined rearwardly with respect to the front face (13) of the blade edge member (12). Earth-moving work can be performed by inclining the blade (10) rearwardly by an angle (.theta..sub.1) with respect to its posture in digging work, and earth-dumping work can be performed by inclining the blade (10) forwardly by an angle (.theta..sub.2) with respect to its posture in digging work. The coupling positions of the two pitch cylinders (4A, 4B) can be in asymmetrical relation to each other. Control signals can be provided by a blade lever (23), tilt/pitch changeover switch (24), and pitch speed changeover switch (25). The tilt/pitch changeover switch (24) and pitch speed changeover switch (25) can be replaced by pitch-dump selector switch (25A) and pitch-back selector switch (24A).

摘要： An impact ripper (2) mounted on the rear portion of a construction machine, such as a bulldozer (1), for digging a hard soil layer is automatically controlled to reduce the operator's fatigue, to improve operability with regard to the posture of the impact ripper during operation of its vibrating mechanism (3), and to prevent breakdown of the impact ripper caused by wasteful striking. A vehicle tractive force and a vehicle speed required by digging resistance applied to a blade end (2a) of the impact ripper (2) are detected and signals obtained from the detections are inputted to a controller (4). When an automatic strike switch is on, an activating signal is outputted from the controller (4) to the vibrating mechanism (3) of the impact ripper (2) regardless of a vehicle body tractive force when a vehicle speed is less than a predetermined value. On the other hand, when the vehicle speed is equal to or grater than the predetermined value, an activating signal is outputted from the controller (4) only when the vehicle body tractive force is equal to or greater than a predetermined value.
