Title: Focus servo device
Inventor: SHIRAGAMI KAZUHARU
IPC: G11B7/085
Filed: 1985-01-31
Abstract: PURPOSE:To prevent the heating of the coil of the actuator and to decrease the noise by limiting a focus error signal at the time of the access and limiting the electric current which flows at the actuator for the focus. CONSTITUTION:While the access is not executed, and access control circuit 7 sends the signal showing that the access is not executed to a limiter circuit 8, and the limiter 8 outputs the inputted signal without the limit, and therefore, the focus servo is normally operated. Namely, when the signal, which is not accessed, is inputted to a terminal F of the circuit 8, a switch 11 is turned off, a servo error signal inputted from a terminal D is not attenuated and outputted to a terminal E. On the other hand, the signal showing that the access if executed is inputted into the terminal F. and then, the switch 11 is turned on, and a servo error signal inputted into the terminal D is limited by the voltage determined by the forward direction voltage of the diode and outputted from the terminal E.

Title: Magnetic disk device
Inventor: SATO HISASHI
IPC: G11B21/10
Filed: 1987-01-28
Abstract: PURPOSE:To make a finer pitch for data track and to enable the positioning with high accuracy by arranging a longer distance from the revolution center of an actuator to a servo head than to other heads and making a wider working area for servo information than a working area for the other heads. CONSTITUTION:The distance from the revolution center 11 of the actuator to the servo head 5 is settled as longer than the distance to the other heads. In other words, since the servo head 5 is fixed in a farther position than an inner head 3 and outer head 4 as of the data head from the revolving center 11 of the actuator, a movable area of the servo head 5 is widen more than that of the data head. In this way, the positioning accuracy of the data head can be improved by widening the pitch of a servo track, and on the other hand if the track pitch for the servo is made in an equal density as before, the positioning of the data head can be performed with higher accuracy.

IPC: B21J5/00
Filed: 1999-01-27
Abstract: PROBLEM TO BE SOLVED: To make it possible to add a high strain area securely and uniformly to a workpiece using forging dies normally used without manufacturing new forging dies each time when product dimensions are changed, by putting a spare metallic material having a deformation resistance value similar to that of the workpiece at the forging temperature between the workpiece and the forging dies.

It is possible to optionally select the spare material 2 in consideration of the workpiece 1 and the deformation resistance value at the forging temperature, and the deformation resistance value of the spare material 2 is to be within the range of 50-200% of that of the workpiece at the forging temperature. This preform is forged, and a low- strain area 4 is caused to exist only on the portion of the spare material 7 after forging, and a product portion 3 is added with high strain of a specified value or higher to sufficiently cause plastic deformation. Then, the spare material 7 with the low-strain area 4 is removed to the cut portion 5 by cut processing.

Title: Position detector
Inventor: UCHIDA GEN
IPC: G02B27/00
Filed: 1993-02-05
Abstract: PURPOSE:To allow the selective switching of the extending direction of scanning beam by forming a stripe beam spot on an object and shifting the beam spot relatively to a mark put on the object thereby detecting the position of the mark. CONSTITUTION:When a stage 4 is moved in X-direction and a stripe beam spot Spa impinges on an alignment mark AMa, diffracted light is produced from the mark AMa. The diffracted light passes through an objective lens 16a, a beam splitter 15a, and a relay lens 18a to a photoelectric detector 19a where it is subjected to photoelectric conversion. Since the diffracted light from the mark AMa has a maximum intensity when the spot SPa is superposed on the mark AMa, position of the mark AMa can be detected based on a maximum value of photoelectrically converted output from the photoelectric detector 19a. Alternatively, scanning can be carried out with the spot SPa using an oscillatory mirror or the like or the marks AMa, AMb can be imaged using an observation camera 22.

IPC: G05B19/418
Filed: 1988-01-29
Abstract: PURPOSE:To attain more efficient application by allowing a control device body to previously transfer NC data to be used based on an operation schedule to a corresponding repeating processor by using its control idle time. CONSTITUTION:When an operation schedule is determined in a random access system, the kind (NC tape number) of a work to be successively worked can be determined by referring the operation schedule and which NC control machine is to be started can be known. When NC data to be used are previously transferred to a repeating processor out of processors 210-250 which corresponds to an NC machine to be started by utilizing a control idle time, required NC data transmission processing can be attained only by sending a working command having sufficiently small volume of information at the time of generating practical use of the same NC data to the processors 210-250. Consequently, a control device body 110 can be transferred to the succeeding processing directly after sending the working command.
