摘要： An extrusion press includes a means which can prevent phenomena in which a billet is blown out during an extrusion process as well as prevent billet blowout with a simple and inexpensive constitution. The extrusion press drives a main cylinder device to extrude, by a stem , a billet filled into a container from a die and form a product. A gap measurement means that measures a gap arising at the container seal surface formed by pressing the die side end surface of the container against the container side end surface of the die is provided on an end platen on the outer edge part of the container side end surface of the die. When the gap arising during the extrusion process is measured and the measured value is within a predetermined range of allowable values, a set value for the extrusion rate is lowered and a warning is issued. When the measured value exceeds the predetermined allowable values, the extrusion process is stopped.

摘要： With a large capacity of an optical disk and high-speed recording, a frequency of a recording signal is increased and a pulse width is narrowed. In the case that a laser is driven by a signal having the short pulse width, unfortunately the high-speed recording is hardly performed to an optical disk when a rise time and a fall time of the optical pulse are lengthened.During user data recording, a bottom driving current is set to a second bottom driving current value that is a current value of a threshold or less, so that the rise time and the fall time of the optical pulse can be shortened to perform the high-speed recording of the optical disk.

摘要： The invention provides a tracking control device, a tracking control method, and an optical disc apparatus that enable to stably perform the tracking control, and reduce an influence of stray light from the other layer on the tracking control. A sub push-pull signal correcting section corrects a sub push-pull signal to be generated from returning light of a sub beam in such a manner that a track crossing component of a main push-pull signal to be generated from returning light of a main beam, and a track crossing component of the sub push-pull signal to be generated from the returning light of the sub beam are canceled. A low pass filter reduces a high frequency component of the sub push-pull signal corrected by the sub push-pull signal correcting section. A subtractor subtracts a sub push-pull signal passing the low pass filter from the main push-pull signal to thereby generate a tracking error signal.

摘要： A first comparator (112a) compares a first voltage signal to a predetermined threshold to output a first binary signal corresponding to a comparison result. A second comparator (112b) compares a second voltage signal to a predetermined threshold to output a second binary signal corresponding to a comparison result. A first digital sampling section (113a) samples the first binary signal output by the first comparator 112a to generate a first sampling signal. A second digital sampling section (113b) samples the second binary signal output by the second comparator (112b) to generate a second sampling signal. A phase difference detector circuit (114) detects a phase difference between the first sampling signal generated by the first digital sampling section (113a) and the second sampling signal generated by the second digital sampling section (113b).
