Abstract: ABSTRACT         An expansion dowel assembly is used to anchor a part to the surface of a structural member.  The expansion dowel assembly is inserted into and anchored within a borehole in the structural member.  The assembly includes a support tube, an anchor rod extending axially through the support tube, and expansion elements positioned within the support tube so as to be radially displaced by the anchor rod into anchoring engagement with the structural member.  The expansion elements are positioned within the support tube in bearing contact with respective support surfaces.  The support surfaces contacting the expansion elements face toward the bottom of the borehole into which the dowel assembly is inserted.  The support surfaces are formed as webs as parts of the support tube.  When a force acting on the anchor rod exceeds a predetermined level, the expansion elements apply force to the webs,     they yield, or break, thereby permitting axial movement of the expansion elements.

Abstract: Abstract of the Disclosure:     In a pager receiver comprising a display circuit and an ROM, a controller produces a test mode signal indicative of a test mode in which either the display circuit or the ROM is tested. Responsive to the test mode signal, the ROM supplies the display circuit with a succession of display signals which are previously stored therein and representative of all alphanumeric symbols displayed by the display circuit, so as to test the display circuit.  Alternatively, all of contents stored in the ROM are successively sent from the ROM to the display circuit in response to the test mode signal on testing the ROM, so as to inspect the contents.  The test mode signal may be delivered from a transmitting end to the controller in the form of a radio calling signal or given to the controller by manual operation.  The test mode signal may specify more than two sorts of tests.
