  • Publication number: 20180335736
    Abstract: A fixing apparatus is operable in relation to either of a first nominal voltage and a second nominal voltage, as an alternating voltage of a commercial alternating current power supply. The apparatus detects the alternating voltage and a temperature of a first heater or a first rotating member. A driving circuit supplies to the first heater a power if a drive signal is being inputted, and to not supply to the first heater the power if the drive signal is not being inputted. A controller determines a duty ratio of the drive signal to be a first duty ratio or a second duty ratio smaller than the first duty ratio.

  • Publication number: 20180096538
    Abstract: After an air-bag inspection device (10) is set to a steering wheel (12), a lock release lever (48) is operated to move a lock plate (44) from a lock position to a lock release position, thereby releasing lock of a rotating plate (43). A coil spring (38) is urged to allow a left and a right clamp shafts (33) (34) to press an inner peripheral surface of the steering wheel (12). This pressing force allows the air-bag inspection device (10) to be attached to the steering wheel (12). When the start button (51) is pressed, a left sensor (14) and a right sensor (15) measure a distance to the air-bag (11). When measurement data falls within a preliminarily set predetermined range, a control device (16) determines that the air-bag (11) is properly attached to the steering wheel (12) and turns on an OK lamp (53).

  • Publication number: 20170369325
    Abstract: In order to produce high-purity trichlorosilane by removing methyldichlorosilane from a mixture (S) containing methyldichlorosilane (CH3HSiCl2), tetrachlorosilane (SiCl4), and trichlorosilane (HSiCl3) in the method for producing trichlorosilane of the present invention, a procedure is employed in which chlorine atoms are redistributed between methyldichlorosilane and tetrachlorosilane through catalytic treatment for conversion into trichlorosilane and methyltrichlorosilane (CH3SiCl3). Methyldichlorosilane (boiling point: 41° C.) having a boiling point close to that of trichlorosilane (boiling point: 32° C.) to be purified is converted into methyltrichlorosilane (boiling point: 66° C.) having a higher boiling point through redistribution of chlorine atoms between methyldichlorosilane and tetrachlorosilane, achieving easy removal of impurities.
