  • Patent number: 8520485
    Abstract: A recording apparatus includes the following elements. A recording light source emits pulse laser light for recording. A first light source emits first CW laser light. An irradiation optical system irradiates an optical recording medium with the pulse laser light and the first CW laser light via an objective lens in the state in which the optical axis of the first CW laser light is tilted with respect to the optical axis of the pulse laser light. A reception optical system outputs, to a first light receiver, a returned light portion of the first CW laser light which has been reflected by a reflection surface formed on the optical recording medium and which has been input through the objective lens. A focus servo controller performs focus servo control for the objective lens on the basis of a first reception signal obtained by the first light receiver.

  • Publication number: 20120186604
    Abstract: According to one embodiment, a cleaning gas is sealed in a chamber of a semiconductor manufacturing apparatus, and the cleaning gas and deposits adhered in the chamber are reacted with each other to generate a reactive gas. After a predetermined time, the gas is exhausted from the chamber. Then, the chamber is evacuated while the cleaning gas is introduced into the chamber, and the reactive gas concentration contained in an exhausted gas is measured. The reactive gas concentration is compared with a determination value obtained when the deposits are removed from the chamber to determine whether the cleaning is terminated.
