Abstract

A mechanical timepiece includes: a hairspring; a permanent magnet; a soft magnetic core; a control circuit for performing rate adjustment based on a counter-electromotive voltage caused in a coil by a motion of the permanent magnet accompanying a forward direction motion and a reverse direction motion of the balance wheel. The permanent magnet is arranged so that, under a state in which the hairspring is brought to an equilibrium length, a direction of magnetization is directed to the first end portion side or the second end portion side.

Abstract

A machining device threads a workpiece by relatively rotating the workpiece and a multi-blade tool and relatively moving them along a feed direction to perform cutting processes in the radial direction of the workpiece along the same cutting path in a predetermined spiral form. A controller performs a groove machining to form a threaded portion with vibration in the radial direction of the workpiece and a finish machining to form the threaded portion by bringing the multi-blade tool into contact with the grooved portion of the workpiece. The multi-blade tool has a first cutting blade and a second cutting blade arranged side by side along the feed direction. The controller sets amplitude of a vibration waveform to a value at which a cutting edge of the second cutting blade does not come into contact with the screw bottom surface of the workpiece in the finish machining.

Abstract

A portable communication device cooperation system includes a slave portable communication device that can communicate with a master portable communication device. Each of a plurality of slave-side slots of a slave-side storage unit included in the slave portable communication device stores a slave application program transferred from a master-side slot disposed in the master portable communication device. The slave application program includes part of information of a master application program, and causes the slave portable communication device to operate by being executed by a slave-side control unit of the slave portable communication device. As a result, the portable communication device cooperation system, the master portable communication device, and the slave portable communication device exhibit an effect of enabling the slave portable communication device to be variously used.

Abstract

Disclosed is a friction welding method including: a heating step wherein, in relation to joining surfaces (S1, S2) defined by opposite end surfaces of a pair of materials (W1, W2), the pair of materials (W1, W2) are moved from a state in which their axes are unaligned with each other, in a direction for aligning the respective axes with each other, to a prescribed position where the joining surfaces (S1, S2) are brought into contact with each other and friction heated; and a pressure contacting step wherein the pair of materials are brought into pressure contact with each other. The method is characterized in that the heating step and the pressure contacting step are carried out while rotating each of the materials (W1, W2) at the same rotation speed in the same direction, as seen from one side in the axial direction.

A printer includes a print head portion for printing on a label paper, a feeding portion for feeding the label paper, a cutter portion for cutting the label paper, and a controller for controlling operations of the print head portion, the feeding portion, and the cutter portion. The label paper includes a bent portion that is generated in a portion right after unrolled from a label roll and changes in accordance with a label roll diameter. The controller is configured to control the feeding portion to feed the label paper by a constant length set in advance with respect to a predetermined label roll diameter so that a cutting operation by the cutter portion is performed at a position past a bent portion generated when the label roll diameter is larger than the predetermined diameter if the feeding operation for the label paper meets a predetermined condition set in advance.
