摘要: A device for presenting information to a mobile includes mobiles and terminal interconnected intercommunicably through communication means, wherein a terminal transmits, to the mobile concerned, mobile identification data on a mobile to which a request for mobile information is to be made, request content identification data representing the contents of mobile information to be requested, and terminal identification data on the terminal being the presentee to which the requested contents is to be presented. The mobile acquires mobile information requested by the terminal and sends it to the terminal being the presentee. The stored contents in storage means is updated each time operation of input for requesting information from a mobile is made through the terminal and the mobile acquires new mobile information. The updated stored contents is transmitted to the terminal being the requester when the terminal requests the updated stored contents.

摘要: Communications are performed between a mobile unit and a terminal device. The mobile unit is provided with a communication device that is capable of communicating with the terminal device if it is connected electrically with a power supply. When an engine key switch signal is off, the electrical connection between the power supply and the communication device is turned on and off intermittently.

摘要: A first object of the invention is to use a simple hydraulic circuit, which does not use any pressure compensating valve, to enable use of an inexpensive pressure detector of low accuracy, to enable constant maintaining of continuity of control with a simple control and without giving a shock to an operator or mechanical parts, to set no limit on a control system for hydraulic pumps, and to cancel a load-dependency of a flowrate of a hydraulic actuator at the time of combination operation. In a device according to the invention, a correction factor for correction of a control input of an operating member corresponding to an associated operating valve on the basis of a ratio between a detected differential pressure across the associated operating valve and a minimum differential pressure selected from among detected differential pressures across a plurality of operating valves is calculated for each operating member. A control input of an operating member corresponding to the associated operating valve is corrected by the calculated correction factor. A second object of the invention is to enhance an operating efficiency by enabling changing of pressure compensating characteristics of the hydraulic actuator according to an operating state and a load pressure of an operating lever. In a device according to the invention, an upper or lower limit value of the correction factor is set for each operating member according to a control input of the operating member, and an associated correction factor is used to correct a control input of a corresponding operating member in such a manner that the set upper or lower limit value is not exceeded by the associated correction factor which is obtained according to the detected differential pressures.
