摘要： A method of rolling with flat cutters having finishing blades for rolling a periphery of a pipe. In working, the pipe is rotatably supported at both ends by a pair of centers, a pair of flat cutters which have a plurality of corrugated finishing blades formed on a substantially triangular blade base are disposed such that the finishing blades face each other and the directions of the finishing blades are parallel to an axis of the pipe, and the flat cutters are moved rectilinearly in opposite directions to each other from an initial working position to a terminal working position such that one end of each finishing blade presses the pipe. Thus, the periphery of the pipe is progressively worked axially from one end of the pipe.

摘要： A rolling flat cutter having finishing blades corresponding to corrugation of a product to be obtained by working a tubular or cylindrical workpiece, and a method of rolling by the flat cutter. When the workpiece is worked, a pair of flat cutters are disposed such that the finishing blades face each other, and the cutters are moved rectilinearly in opposite directions perpendicular to a direction in which the finishing blades extend so that the corrugation is formed on a periphery of the workpiece from an end to the other in an axial direction thereof. As to the rolling flat cutter, a flat cutter is used which comprises a rectangular cutter body, a triangular blade base formed as a higher step on one side of a plane of the cutter body along a straight line parallel with a diagonal of the plane, and the finishing blades are formed on the blade base.

摘要： A cordless telephone consisting of base and handset units is disclosed wherein a control circuit incorporated in the base unit comprises first and second D/A converters, first and second A/D converters, and first and second sync. signal generation circuits. The first and second D/A converters respectively convert digital signals from the handset unit and a PBX. The first and second A/D converters convert the analog signals provided from the first and second D/A converters to transmit them to the PBX and handset unit, respectively. The first sync. signal generation circuit regenerates a first clock signal synchronously with a sync. signal provided from the PBX to render the first A/D and second D/A converters to operate in synchronism with the sync. signal from the PBX. The second sync. signal generation circuit generates a second clock signal which is independent of the sync. signal from the PBX to render the first D/A and second A/D converters to operate in synchronism with the second clock signal. Accordingly, the synchronization between the base and handset units is effected independently of the synchronization signal from the PBX.

摘要： An antenna device for a radio transmission-reception apparatus is disclosed which comprises an antenna element which is to be electrically and mechanically connected to a printed-circuit board fixed in a housing of the radio transmission-reception apparatus, an inverted U-shaped hollow reinforcement spacer, an antenna cover and a retaining portion formed on the housing. The reinforcement spacer has a hole formed in the top portion thereof a diameter of which is substantially equal to that of the antenna element to slide therethrough, a slit formed continuously from the hole to a base end thereof through which said antenna element can be entered in the reinforcement spacer, and a flange formed around the outer circumference of the base end. The antenna cover is constituted to accommodate therein the antenna element with the reinforcement spacer, and has a flange formed around the circumference of a base end thereof. The flanges of the antenna cover and the reinforcement spacer are fixedly supported in the retaining portion provided on the housing in a state that said flanges are stacked upon each other. Since the most of forces caused by vibration and/or impact supplied to the antenna element are absorbed by the reinforcement spacer, a mechanically and electrically connected portion between the antenna element and the printed-circuit board will be effected by the forces and thus damage to the portion will be eliminated.
