Abstract: In a data processing system, a plurality of modules connected to a system bus thereof are assigned with identifiers. When a source module initiates a split read access to another module, the source module sends an address of the access destination module and an identifier of the source module. When sending a response to the source module, the destination module returns response data and the identifier of the source module thereto. Checking the identifier from the destination module, the source module determines the response data returned as a response to the initiated access.

Abstract: In an electronic caliper, a detecting circuit 112 detects displacement of a grid with respect to a scale, on the basis of a signal from a transducer 110. A CPU 114 displays the detected position on a display device 124. The CPU 114 performs error detection on the transducer, only when the relative speed of the grid with respect the scale is zero, or becomes equal to or smaller than a predetermined value. Since error detection is performed only at a predetermined timing, power consumption can be reduced.

Abstract: In a discharge lamp sealing apparatus 30, luminescent substances are charged into an arc tube 11 through an opening 13b thereof, and an electrode member 15 is then inserted into the arc tube 11 through the opening 13b. A lower end of the arc tube 11 is supported by a support jig 57 in a state that a glass ring 16c is placed around the circumference of the opening 13b. The arc tube 11 is set in an air-tight condition by a feeding conduit 51 and inserted into a heating unit 40. The heating unit 40 fuses the glass ring 16c with heat of an infrared lamp and thereby seals the opening 13b. During the sealing process, one end of the arc tube 11 is supported by the support jig 57. The support jig 57 is mainly made of a material having a greater thermal conductivity than that of the material of the arc tube 11, for example, a metal material like Al or Cu. This arrangement enables heat to be readily conducted from the arc tube 11 to the support jig 57 and accordingly prevents a temperature rise in the arc tube 11.
