Title: Optical pickup device and optical information recording and reproducing device using the same
Inventor: KOBORI HIROMICHI
IPC: G11B7/125
Filed: 1989-09-30
Abstract: PURPOSE:To form an optical pickup device provided with an error detecting function at real time and an optical information recording and reproducing device by using a diffraction grating and a light beam radiation source provided with a simultaneous oscillating function for TE mode light and TM mode light having the fixed difference of oscillation wavelength. CONSTITUTION:The TE mode light 1A for storing or erasing is oscillated from a light source 1a, reflected by the reflection type diffraction grating 4, condensed 5 and focused on a track on an optical disk 6a. The reflected light is received by a four-division photodetector 10 through the grating 4 and the light splitter 3. Meanwhile, the TM mode light 1B (having the fixed difference of oscillation from the TE mode light 1A) for detecting the error detection and non-erasable remaining signal of a recording signal passes the same optical system as the TE mode light 1A, and it is reflected because of the deviation of the angle of diffraction corresponding to the difference of wavelength from the light 1A by the grating 4 and focused on the track on the disk 6 spaced at regular intervals from the focusing point of the TE mode light. The reflected light is reflected by the splitters 3 and 8 and detected by a photodetector 11. Thus, the optical pickup device provided with the error detecting function at real time and the optical information recording and reproducing device are obtained.

Title: Method of regulating temperature of devices such as machine tool or the like
Inventor: KATAYANAGI MASAMI
IPC: B23Q11/14
Filed: 1986-10-28
Abstract: PURPOSE:To maintain accurate machining accuracy, by sensing a change in a temperature of a device per unit time and, when an amount of the change exceeds a prescribed value controlling a temperature regulating means in such a way that a direction of the temperature change is reversed at a timing earlier than when the amount of the change is smaller than the prescribed amount. CONSTITUTION:A change in a temperature per unit time of a device such as a machine tool or the like is sensed directly or indirectly by a temperature sensor 14 or the like. When an amount of the change in the temperature exceeds a prescribed amount, a temperature regulating means 2 is controlled in such a way that a direction of the temperature change is reversed at a timing earlier than when the amount of the change is smaller than the prescribed amount. As a result, when the device such as the machine tool or the like develops much heat due to an increase in a load and increases its temperature abruptly the device is cooled by a large cooling capacity at an earlier timing when the temperature does not reach the upper limit value. When the cooling speed is accelerated abruptly exceeding a prescribed value, the cooling capacity is reduced at an earlier timing when the temperature of the device reaches the lower limit, whereby the temperature is maintained in a prescribed range.
