Abstract:
(EN) Provided is a drive device in which a gas is sealed in a casing for housing an object to be driven, wherein the concentration of the gas can be determined. The drive device (10) is provided with: a casing in which a gas having a density lower than that of air is sealed; a drive unit (13) for driving a phosphor wheel (12) housed in the casing; a current sensing unit (14) for sensing the current value for a current flowing to the drive unit (13); and a determining unit (15b) for determining the concentration of the gas in the casing on the basis of the sensed current value.
(FR) L'invention concerne un dispositif d'entraînement dans lequel un gaz est scellé dans un boîtier permettant de loger un objet à entraîner, la concentration du gaz pouvant être déterminée. Le dispositif d'entraînement (10) comprend : un boîtier dans lequel un gaz ayant une densité inférieure à celle de l'air est scellé ; une unité d'entraînement (13) permettant d'entraîner une roue luminescente (12) logée dans le boîtier ; une unité de détection de courant (14) permettant de détecter la valeur de courant d'un courant circulant vers l'unité d'entraînement (13) ; et une unité de détermination (15b) permettant de déterminer la concentration du gaz dans le boîtier sur la base de la valeur de courant détectée.
(JA) 駆動対象物を収容する筐体内に気体が封入された駆動装置であって、当該気体の濃度を判定することができる駆動装置を提供する。駆動装置(10)は、内部に空気よりも密度の低い気体が封入された筐体と、筐体の内部に収容された蛍光体ホイール(12)を駆動する駆動部(13)と、駆動部(13)に流れる電流値を検知する電流検知部(14)と、検知された電流値に基づいて、筐体内部の気体の濃度を判定する判定部(15b)とを備える。
