Title: Device and method for controlling motion of servo press
Inventor: DOUJIYOU EIJI
IPC: B30B15/00
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To suppress the vibration or noise during the machining of a servo press by decelerating a slide at a position before a die touch position or a pressurization start position by the prescribed distance. SOLUTION: A position and speed setting means 27 sets the position at which the speed of a slide is switched to the low speed in changing the motion of the slide, and the position at which the speed change is completed, and sets the low speed value of the slide. The data of the newly set position and speed are fed back in a motion storing means 24, and stored there. A servo motor control operating means 28 operates the speed command value to control the speed of the servo motor 11 from the initial motion set data and the newly set data on the position and the speed stored in the motion storing means 24, and outputs the operated values to a servo motor command outputting means 29.  The servo motor command outputting means 29 outputs the current value to the motor 11 so that the deviation between the speed command value and the speed feedback value from a speed detecting means 11a is zero.

Inventor: SUZUKI HISAO
IPC: C01G25/00
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To stabilize a lead zirconate titanate precursor sol soln. in the air by adding a material having a carboxyl group to the sol soln. SOLUTION: A material having a carboxyl group such as acetic acid is added to a lead zirconate titanate [Pb(Zr,Ti)O3 (PZT)] precursor sol soln. by an amt. (mol) 0.5-3 times the amt. (mol) of metallic ions in the sol soln. The surface parts of the colloidal particles are coated with acetoxyl groups in place of hydroxyl groups and further hydrolysis is restricted, therefore the sol soln. does not gel and enables stable coating work even if it is allowed to stand all day long in the air. When a thin PZT film is formed, a PZT precursor sol contg. 20-100 mol.% excessively added lead is preferably used. Conversion into a perovskite single phase is enabled by calcining at a low temp. of 500 deg.C and a low-cost substrate of glass, Al or the like having a low m.p. can be used.

The clearance of the cavity side sealing part 3 is specified to 10 to 70 μm to allow the passage of gas but to prohibit the passage of the molten metal. The mold rear surface side sealing part 4 is formed as the clearance not to allow the passage of the gas and is formed as a structure using, for example, an O-ring. The space 5 for exhaust gases is disposed between the both sealing parts 3 and 4. When the molten metal is packed in the cavity 1, the gas remaining in the cavity 1 passes the cavity side sealing part 3 and is discharged into the exhaust gas space 5.

Abstract: PURPOSE:To provide the optical isolator which has no polarization dependency. CONSTITUTION:Linear polarized light which travels in parallel to this paper surface and has an optional slanting plane of polarization is split by a polarized wave separating element 11 and a component whose electric field of light is parallel to the paper surface travels straight and has its plane of polarization rotated clockwise by a Faraday rotator 21 and is then passed through a polarized wave separating element 31. The other component whose electric field of the light is perpendicular to the paper surface is reflected by the element 11 to the right and is changed in direction by 90 deg. through a reflecting element 12, and the component after having its plane of polarization rotated clockwise by 45 deg. through a Faraday rotator 22 is changed in direction by 90 deg. through a reflecting element 32, further changed in direction by 90 deg. through an optical path movement part 33, and then made incident on a polarized wave separating element 31. The element 31 is set so that a straight polarized component which slants down to the right at 45 deg. to the paper surface can easily be passed, so the polarized light component exiting from the element 33 while slanting down to the left at 45 deg. is changed in direction by 90 deg. and projects in the same direction with the straight traveling component. The light obtained by multiplexing both the light components has its plane of polarization rotated clockwise at 45 deg. to the light made incident on the element 11 and the intensity does not depend upon the polarized state of the incident light.
