Title: Position control method and device thereof for electric discharge machine
Inventor: MORI TAKASHI
IPC: B23Q15/06
Filed: 1991-10-22
Abstract: PURPOSE:To provide a position control method and its device which is capable of position control with high control responsiveness and with high accuracy even during the movement of a table or a working head. CONSTITUTION:In achieving the position control of an electric discharge machine 2 to implement the electric discharge working while realizing the relative movement of tables 8,10 provided with a working head 6 and a work 12, there are provided a rotary encoder 18 and a linear scale 19 to detect the positions after movement of the working head or the tables 8, 10, and these respective detected values are received by a control part 20 and a comparative part 30. This comparative part 30 compares these detected values, and at the same time, a corrective part 32 obtains a movement corrective value D8 on the basis of these results. On the other hand, a control part 20 achieves further positional correction on the basis of the movement corrective value D8 while referring to the movement order DI from a movement ordering part 22 and realizing feedback control on the basis of the detected value D5 of the rotary encoder 18.

Title: Work carrying device using timing screw
Inventor: MAENO HIROYUKI
IPC: B65G47/28
Filed: 1993-12-02
Abstract: PURPOSE:To carry works whose strength is low without damaging them, and carry them out by enlarging an interval between the works, by providing a first conveyor to carry the works at low speed and a second conveyor to carry the works at high speed. CONSTITUTION:A first conveyor 90 carries works 10 at low speed toward an inlet low speed part 30 of a timing screw 20. Thereby, since impact between the mutual works 10 and between the works 10 and a rear end part of the timing screw 20 becomes small, even if the works 10 overturn or strength of the works 10 is low, they are prevented from being damaged. Since carrying speed of the works 10 is increased according to an increase in outlet leads, work carrying speed of a second conveyor 100 is increased according to speed of the works 10 in a front end part of the timing screw 20. However, since the works 10 on this side of the rear end part of the timing screw are carried at low speed by the first conveyor 90, overturning or damage or the like of the works 10 can be prevented.

Filed: 1998-10-23
Abstract: PROBLEM TO BE SOLVED: To prevent the focus servo from being released while suppressing the power consumption and heat generation by changing the gain of the focus servo in accordance with the progress degree at the time of moving an optical head to the objective position of the optical disk. SOLUTION: When the optical head 3 is moved to the objective position on the optical disk 2, the gain of the focus servo is changed in accordance with the progress degree of the movement. When the command to execute the access is received by a control means 9, the gain of the focus servo is increased first, that is, set to the 2nd gain (>1st gain) and increased by the specified value from the 1st gain. Next, the acceleration of the optical head 3 is started by impressing the driving voltage on a thread motor keeping to wait for the specific period. After this specific period is elapsed, the moving speed of the optical head 3 is converged to almost the prescribed value (becomes the constant speed). By means of comparatively increasing the gain of the focus servo at the time of acceleration (acceleration range) of the optical head 3, the focus servo is prevented from releasing.

CONSTITUTION:A sensor 32 detects the slot 9' of a secondary belt 1' to transmit a pulse 34 and, when a stop order is emitted, the slot 9' of the secondary belt 1' is stopped at a point B, that is, a stand-by point by the rising signal of the pulse 34 immediately after said order. Next, when the lead 10 provided to a primary belt 1 running at a constant speed approaches a point A, a sensor 31 present at a distance S from the point A on the side of the primary belt 1 detects the lead 10 to emit a pulse 33 and the secondary belt 1 begins to start the point of time when the lead 10 coincides with the position of the slot 9' of the secondary belt 1. Therefore, when the lead 10 reaches in the vicinity of the point A, the grasping of the primary belt 1 is altered to that of the secondary belt 1' by re-grasping devices 14, 14'.

Title: Liquid crystal display device and its device
Inventor: MORIKAWA MASAHIKO
IPC: G02F1/13
Filed: 1994-12-07
Abstract: PURPOSE: To obtain a good display grade with a fine pixel pitch of about 100μm by forming the period of the waving in the film thickness of oriented films smaller than one pixel pitch and specifying a relation between the oriented films and the dispersion in pretilt angles. CONSTITUTION: The oriented film 25a printed on a TFT element substrate 21 attains a state slightly diluted by the vapor of a diluent and eventually, the viscosity of the film 25a decreases and the part of the large film thickness is pulled downward by gravity, by which the film thickness is reduced. On the other hand, the film thickness is slightly increased in the part where the film thickness is small. As a result, the average difference in the film thickness of the film 25a on the respective pixels 32 is made as small as <=100 angstrom. The dispersion in the pretilt angles of the liquid crystal molecules is decreased to<=1 deg. by lessening the difference in the average film thickness of the oriented films 25b, 25a existing on the respective pixels 32.  As a result, the quantity of the light projected by the pretilt angles of the liquid crystal molecules is made uniform for each of the respective pixels 32. There is no unequal display and the display grade is improved in the case images are evaluated by macro- projecting the images.
