    摘要: In an improved rotary ring winding device wherein a rotary ring member is rotatably supported by a bearing device secured to a ring rail, the bearing device is provided with a first annular magnetic member wherein an annular recess is formed. The rotary ring member is provided with a second annular magnetic member having an annular projected portion which is arranged in the annular recess of the first annular magnetic member with an air-gap therebetween. The first annular magnetic member is provided with at least an annular portion formed by an electric magnet, and the other portion of the first annular magnetic member and the second annular portion are formed by permanent magnets, wherein each annular portion of the first magnetic member and each annular portion of the second magnetic member, facing each other, are designed to have identical magnetic poles. Thus controlling the exciting current applied to the electric magnet, the rotary ring member can be rotatably supported in free condition by the bearing device, and a braking force can be applied on the free rotation of the rotary ring member by controlling the above-mentioned exciting current.

    摘要: A device for detecting the presence or absence of flame in a combustor and an oxygen density of room air used to operate the combustor. An ion current detecting sensor increases a flame ion current value in the combustor to an ion current value at which erroneous detection of the presence or absence of flame is prevented. A timer outputs a high level signal when combustion starts and starts a timer operation for holding the high level signal until the ion current is stabilized. Thereafter, the time outputs a low level signal which grounds a circuit to lower the flame presence or absence detecting ion current value detected by the sensor. A voltage comparator compares a flame presence or absence detecting ion-current developed voltage and a room air oxygen density detecting ion-current developed voltage with a predetermined reference voltage corresponding to a value at which both the presence or absence of flame and the oxygen density in the room can be detected to provide an output signal when the flame presence or absence detecting ion-current developed voltage or the room air oxygen density detecting iron-current developed voltage is larger than the reference voltage.

    摘要: An oxygen density detecting device for a combustor in which individual adjustment of reference levels for each combustor is not necessary. A memory device stores a reference ion current value from a sensor disposed in the combustor for a predetermined period of time extending from the time instant at which combustion breaks out in the combustor until the ion current has substantially stabilized. The oxygen density of the room air used by the combustor is determined by comparing the ion current value stored in the memory with ion current values which are successively provided by the sensing device. An output signal produced thereby is utilized to control circuit elements including a fuel supplying electromagnetic pump and a combustion air blower used for supplying room air into the combustor.
