    摘要： A fluid machine system has such characteristics that the flow rate is proportional to the rotational speed, the produced pressure is proportional to the square of the rotational speed, and the shaft power is proportional to the cube of the rotational speed. The fluid machine system has a first fluid machine actuatable by an induction motor, and a second fluid machine actuatable by the induction motor for producing a flow rate of 1/K and a shaft power of 1/K of those the first fluid machine at the same rotational speed as that of the first fluid machine for generating the same pressure as that of the first fluid machine. The fluid machines having many times of design points can be operated by the same induction motor.

    摘要： A method of producing a ferritic stainless steel strip having reduced intra-face anisotropy as well as excellent r value and anti-ridging characteristics. The method involves subjecting a ferritic stainless steel slab to a hot rolling step including rough rolling having at least one rough rolling pass and a finish rolling having at least one finish rolling pass, followed by a hot-rolled sheet annealing, pickling, cold rolling and finish annealing. At least one of the passes in the rough rolling is conducted with the rolling temperature between about 970.degree. C. to about 1150.degree. C., the friction coefficient between the rolls and the rolled material of about 0.3 or less, and the rolling reduction ratio between about 40 to about 75%.

    摘要： A circulator includes a circulator element (50) with inner conductors (41) having a predetermined pattern and an insulating ferromagnetic material body (40) closely surrounding the inner conductors. The insulating ferromagnetic material body is constituted by a fired single continuous body. The circulator also includes a plurality of terminal electrodes (76) formed on side surfaces of the circulator element and electrically connected to one end of the inner conductors, a plurality of circuit elements (51a, 51b, 51c) electrically connected to the terminal electrodes, and excitation permanent magnets (52, 53) for applying a dc magnetic field to the circulator element.
