摘要： The stem slide device of the present invention in an extruder has a stem vertical movement support (71) and slide guide members (72-1, 2) fastened to the support and forming guide grooves. A stem (6) pushing against a billet loaded in a container is held at the slide table (73) horizontally. The slide table slides in the vertical direction along the vertical face of the support. When the slide table is positioned at the bottom end of the guide groove, the hydraulic cylinders (77-1, 2) are driven so that the rods (78-1, 2) push the back surface of the slide table against the vertical face of the support. Therefore, the axis of the stem is held matched with the axis of the container.

摘要： To adjust the symmetry of a focus error signal, the symmetry of the focus error signal needs to be measured during upward and downward driving of an objective lens, which is performed at every varying setting of a signal correction gain value of the focus error signal, and such adjustment takes a long time. An optical disc device (100) measures a focus error signal before differentiation at a local maximum point and a local minimum point of a focus error signal using a prior-to-differentiation FE measurement unit (50), and calculates the symmetry of the S-shape of a focus error signal using a symmetry calculation unit (51), and performs balance adjustment based on the calculation result. The device with this structure adjusts the symmetry of a focus error signal at a high speed by requiring an upward and downward operation to be performed only once.
