    摘要: There is provided a fluorescent lamp comprising a tubular glass bulb, an internal electrode provided at the center of the tubular glass bulb, a fluorescent layer formed on an inner surface of the tubular bulb, and an external electrode provided on an outer surface of the tubular glass bulb, said tubular glass bulb being charged with a rare gas containing xenon as a main ingredient, wherein the charged pressure of the rare gas is 100 to 300 torr, the inner diameter of the tubular glass bulb is 4 to 12 mm and the thickness of the tubular glass bulb is 0.4 to 1.2 mm. As a result, lighting voltage is greatly reduced, whereby the charged pressure of the rare gas can be increased, thereby making it possible to improve illuminance.

    摘要: A servomotor controller by which a load on a machine device can be reduced, and control capability can be stabilized as well as the resistance property for a temporary blackout or a temporary voltage drop can be more secured in accordance with driving conditions of the machine device and a motor load. The servomotor controller includes: a bus voltage detector for measuring a bus voltage, and a current detector for detecting current passing through a servomotor. A controller 9 switches, depending on the bus voltage, a position control operation with a velocity control operation, to decrease the current supplied to the servomotor in a case where the bus voltage is lower than a first predefined reference voltage.

    摘要: A fluorescent lamp includes a tubular glass bulb, an internal electrode provided substantially along the central axis of the tubular glass bulb, a fluorescent layer provided on the inner surface of the tubular glass bulb, and an external electrode provided on the outer surface of the tubular glass bulb, wherein the internal electrode, having a coiled shape, is laid in the tubular glass bulb with an appropriate tension. According to the present invention, it is possible to prevent a sag in the internal electrode from occurring due to a difference in coefficient of thermal expansion between the tubular glass bulb and a metallic member forming the internal electrode, and to prevent either the tubular glass bulb or the internal electrode from being broken because of an excessive stress, thereby overcoming the problem concerning such type of fluorescent lamp.

    摘要: A sewing machine arrangement comprises a sewing machine, a motor for driving a spindle, and a motor for operating a two-axis drive mechanism. When the two-axis drive mechanism is driven at a maximum speed, processing is executed in which a speed (t) slower than the maximum speed is inserted by a program. Further, drive current flowing through the motor for driving the two-axis drive mechanism is set. A phase exciting method of a stepping motor is switched.
