摘要： A terminal of a motor is provided, in which a connection between a coil and an external circuit can be carried out securely and with a good workability, while saving material resources and enhancing safety relating to environmental pollution. A terminal (23) consists integrally of a magnet wire binding section (20) to connect to a magnet wire (4) of a coil (6), an external connection section (21) to connect to an external circuit and a support base section (22) to press-fit into a terminal block (19) of a bobbin (5) and hold the terminal (23), and the magnet wire (4) is plasma welded for connection through to the external connection section (21) (terminal 23). The connection of the terminal is carried out by welding (plasma welding), thus the end of the magnet wire of a motor (1) is connected without using solder containing lead. As a result, since lead is not used, material resources can be saved and safety relating to the environmental pollution can be enhanced. Since the support base section (22) press-fits into a hole of the terminal block (19) of the bobbin (5), a direction and position of the terminal (23) are settled to thereby increase the stability.

摘要： An electromagnetic actuator with high performance such as high speed and high resolution is inexpensively provided with solutions to problems associated with power supply and leakage flux, which have been involved in the structure of a moving coil type and have been shortcomings of a VCM type actuator. A composite electromagnetic actuator apparatus employs the foregoing electromagnetic actuator. The electromagnetic actuator is equipped with a stationary assembly that includes two coils disposed coaxially with each other inside a hollow stator yoke composed of a soft magnetic material, and a movable assembly composed of a movable magnet unit and a movable yoke unit both disposed inside the coils with a very small clearance therefrom so as to be movable in the axial direction, wherein the movable assembly travels in the axial direction by the interaction between a magnetic field generated by the movable magnet unit and a current passing through the coils.

摘要： A press felt for use in a papermaking machine comprises a base body, a batt material and a hydrophilic nonwoven fabric, all intertwiningly integrated by needle punching. The batt material comprises a staple fiber, and is composed of a wet paper web side layer and a press side layer. The hydrophilic nonwoven fabric is provided in the wet paper web side layer. The hydrophilic character of the nonwoven fabric improves the movement of water to the nonwoven fabric, and the holding the water in the nonwoven fabric. As a result rewetting is prevented more effectively than in the case of prior press felts.
