Abstract: Toner of the present invention is produced by mixing in an aqueous medium at least a resin particle dispersion in which resin particles are dispersed, a colorant particle dispersion in which colorant particles are dispersed, and a wax particle dispersion in which wax particles are dispersed and heating and aggregating the mixed dispersion. The main component of a surface-active agent used for the resin particle dispersion is a nonionic surface-active agent. The main component of at least one surface-active agent selected from a surface-active agent used for the wax particle dispersion and a surface-active agent used for the colorant particle dispersion is a nonionic surface-active agent. With this configuration, the toner can have a smaller particle size and a sharp particle size distribution without requiring a classification process.

Abstract: A mobile terminal that ensures smooth, continuous communications sessions even when in transit, regardless of base station capabilities and functionalities, in a packet-switched data communications network. With this terminal, each of a plurality of lower interfaces 101-1 to 101-M, when its associated access mechanism is in an active state, can obtain a connection to packet-switched data communications network 150 using its home-address HoA.1 or its care-of-address CoA.BS1. When lower interface 101-a loses its connection obtained using the care-of-address CoA.BS1, multiple access decision unit 104 instructs mobility support unit 102 to set up a binding of the home-address HoA.1 and either one of the home-address HoA.2 and the care-of-address CoA.BS2 of another lower interface 101-b. Mobility support unit 102 sets up the binding according to the instruction from multiple access decision unit 104.

Abstract: The present invention is related to an angular velocity sensor, and intends to improve the detection characteristic through a precise measuring of an angular velocity signal. For this objective, the invented angular velocity sensor comprises U-shape first and second piezoelectric elements(4),(5) bonded together sandwiching a detection electrode(6), wherein in at least one of the tuning fork arms(4a),(5a) the first and second piezoelectric elements(4),(5) are polarized in a direction of thickness along which the piezoelectric elements are bonded together. Driving electrodes(7),(12) and (8),(11) provided in diagonal arrangement on the tuning fork arm are supplied with driving signals inverse-phased to each other. In such a structure, the driving signals cancel to each other at the vicinity of detection electrode; as a result, the driving signals never mix with a detection signal to be detected by the detection electrode(6). Thus, the capability of detecting an angular velocity signal is improved.

Abstract: A cutting tool is fixed to a cutting tool holder in such a manner that the posture of the cutting tool can be adjusted without being removed from a processing machine. The cutting tool holder is fixed to a fixing base to allow the cutting tool holder to be fixed in the same position thereof repeatedly with high reproducibility. After the flank of the cutting edge of the cutting tool is measured by an objective interference microscope, the posture of the cutting tool with respect to the cutting tool holder is adjusted so that an interference fringe coincides with a predetermined interference fringe.
