Title: Multi-channel acoustooptical modulator with opening of each cell connected in one line
Inventor: SON TEIEI
IPC: G02F1/11
Filed: 1997-01-28
Abstract: PROBLEM TO BE SOLVED: To enable highspeed inputting and to use pulse laser as a light source by reflecting an acoustic wave from a piezoelectric transformer on a unit crystal side face, advancing it to other side face to form a moving diffraction grating for incident light, and thereby reducing time for inputting data. SOLUTION: If a radio frequency signal from a video line or a computer- formed hologram signal is imparted to a piezoelectric transformer 22 by an electrode 24, 25, an acoustic wave 26 is generated through the piezoelectric effect of the transformer 22. This acoustic wave 26 is propagated into a unit crystal 21 in a direction vertical to the lower face 31, reflected on the side face 32 of the unit crystal 21, and advanced parallelly to the lower face 31. Thenceforth, it is reflected on the opposite side face 33, advanced in the direction vertical to the lower face 31, and finally absorbed in an acoustic absorber 23. An incident laser beam 28 is made incident at a specific angle on the grating 27 inside the crystal 21 generated by the acoustic wave 26, and then diffracted or transmitted by the grating 27.

Title: Screw tightening device
Inventor: MATSUMURA MASAFUMI
IPC: B23P19/06
Filed: 1994-02-07
Abstract: PURPOSE:To make accurate judgement about the acceptability and non- acceptability of a tightened screw, compared with the case of judgement only on the basis of torque data, without complicating constitution. CONSTITUTION:The variation of rotation during a time from the occurrence of the first set torque to the occurrence of the second set torque is compared with the required range preset so as to correspond to the variation of rotation for a properly tightened condition. If the variation during the time is within the preset range, screw tightening is judged to proper. On the other hand, the screw tightening is judged to be improper, if the variation is outside the preset range. Also, even when the second set torque occurs at subsequent tightening processes, including the case where a male screw 110 comes in contact with a foreign substance and seems to be as if seated on a workpiece W, or the forward end of the screw 110 collides with the bottom of a blind hole Wb before seated on the workpiece W, the variation of rotation in this case is clearly different from the variation of rotation observed at a process from normal seating to tightening. Thus, the variation is judged to be outside the preset range and the screw tightening is judged to be improper.
