Abstract: An indication displayed by a display unit included in a pressure switch is inverted and the respective setting functions of push-button switches are reversed when the operator is obliged to look at the display unit from a direction opposite a normal looking direction or when the pressure switch is installed in an inverted position. A mode setting push-button switch 113 is operated to turn the indication indicating a set pressure displayed by a display unit 116 through an angle of 180°, a function to increase the set pressure of a first push-button switch 111 is reversed and a function to decrease the set pressure of the second push-button switch 112 is reversed.

Abstract: The present invention aims to provide a common platform for providing location information, which provision corresponds to network integration.

Abstract: A printing system is designed to reduce the overall time and the cost required for printing patterns on objects such as musical instruments and prevents printed patterns from being partially extended or distorted. Image data representing prescribed patterns are processed in response to object form data representing the form of an object, wherein upon receipt of a user's print instruction, an RGB color inkjet printer ejects ink onto a prescribed surface of the object on the basis of the processed image data. Image data can be produced by picking up an image of another surface of the object, which is transferred onto the prescribed surface of the object, thus establishing a sense of unity in visual sensation therebetween. Alternatively, image data can be processed in correspondence with the selected surface of the object, so that the prescribed image is printed on the selected surface of the object.

The positional information service server acquires the positional information of the mobile unit based on the selected measuring system, and transmits it to the terminal designated as the one to be notified.

Abstract: Menu data supplied from an IP server 500 to a mobile station 101 is embedded with a location information substitution data string “NULLAREA” together with a URL of a particular IP server 500. The mobile station 101, upon detection of the location information substitution data string from a menu data selected by the user, determines whether location information can be transmitted to the IP server 500. In the case where the determination is that the transmission is permitted, the mobile station 101 detects its location information and, after substituting the location information for the location information substitution data string, transmits the data to the IP server 500.
