Abstract: The present invention provides an automated experiment apparatus and an automated experiment method using the same for putting a sample into a pressure vessel and automatically performing a chemical and/or physical reaction of the sample under a predetermined temperature and pressure. According to the embodiments of the present disclosure, it is possible to automatically perform an experiment from the beginning to the end without intervention of an user. As a result, it is possible to prevent a risk of gas leakage and human exposure to a harmful gas due to a manual operation. The apparatus comprises a controller which is configured to automatically perform a reaction process under a predetermined temperature and pressure in a state in which a sample holding member is air-tightly fixed to a pressure vessel and the sample is accommodated in a sample receiving chamber of the pressure vessel.

Abstract: An optical pickup apparatus according to an embodiment includes a semiconductor laser, an objective lens, a grating, and a light detecting device. The grating is installed between the semiconductor laser and the objective lens to divide the light beam emitted from the semiconductor laser into three beams or more including a main beam and a sub-beam. The light detecting device receives the divided light reflected by the optical recording medium. The grating includes a first diffraction grating and a second diffraction grating. The first diffraction grating has patterns formed for dividing a sub-beam with respect to a first optical recording medium having a first track pitch, and second diffraction grating has patterns formed for dividing the sub-beam divided by the first diffraction grating into sub-beams with respect to a second optical recording medium having a second track pitch.
