Patent number: 9022572Abstract: A projection apparatus includes a time-sharing light emitting device, a display device, a projection optical system, an illuminance sensor and a lighting determination unit. The time-sharing light emitting device successively emits color lights one by one. The display device modulates the color lights to form an image. The projection optical system projects the image. The illuminance sensor converts illuminance of the color lights into an electric signal which is an output of the illuminance sensor. The lighting determination unit compares the output with a first threshold value, and operates the time-sharing light emitting device in response to the output being more than the first threshold value, and stops the time-sharing light emitting device in response to the output being equal to or less than the first threshold value.Type: GrantFiled: March 12, 2013Date of Patent: May 5, 2015Assignee: Casio Computer Co., Ltd.Inventor: Atsushi Hara

Publication number: 20100266961Abstract: In a substrate stage device, when an X coarse movement stage moves in an X-axis direction, a Y coarse movement stage, an empty-weight cancelling device and a Y beam move integrally with the X coarse movement stage, and when the Y coarse movement stage moves in a Y-axis direction on the X-coarse movement stage, the empty-weight cancelling device moves integrally with the Y coarse movement stage in the Y-axis direction on the Y beam. Since the Y beam is arranged extending in the Y-axis direction in a state of covering a movement range of the empty-weight cancelling device in the Y-axis direction, the empty-weight cancelling device is constantly supported by the Y beam regardless of the position of the empty-weight cancelling device. Accordingly, a substrate can be guided along an XY plane with high accuracy, without providing a member (e.g. a surface plate or the like) having a guide surface that is large enough to cover the entire movement range of the empty-weight cancelling device.Type: ApplicationFiled: April 21, 2010Publication date: October 21, 2010Applicant: NIKON CORPORATIONInventors: Shuji KAWAMURA, Atsushi HARA
