Title: Correction mechanism of leaf type digital watch
Inventor: MORISHIMA HIDEKI
IPC: G04C9/08
Filed: 1979-08-24
Abstract: PURPOSE:To enable accurate time correction, by correcting the timing shift between a given period signal with the reset switch and the renewal signal from the leaf retaining spring. CONSTITUTION:When the reset switch 15 is operated in matching with the normal time cast, the 60X60 notation counter 14 inputting the 1Hz signal from the frequency dividing circuit 4, produces a given period signal, and this is output to the lag and lead discrimination circuit 16. On the other hand, the renewal signal corresponding to the renewed period of the leaf plate is output from the specified leaf retaining spring 36 and it is output to the discrimination ciricuit 16. Next, the discrimination circuit 16 discriminates the shift in the timing of both the inputs and the result is fed to the control ciricuit 6. The control circuit 6 adds the correcting drive pulse if the shift in the timing is lag and blocks the passing of the drive pulse when lead, to control the motor 12. Thus, the time can accurately be corrected.

Title: Speed controller
Inventor: SHIMIZU ITSUO
IPC: H02P29/00
Filed: 1983-06-17
Abstract: PURPOSE:To reduce the variation in the speed to the abrupt variation in a load by calculating the auxiliary current command value based on the presumed load torque value calculated by a speed signal and a current signal, and adding the auxiliary current command value to the current command value. CONSTITUTION:A speed controller 4 outputs a current command IP in response to the deviation between the speed command VP and the speed signal V. On the other hand, the speed signal V is differentiated by the function of the presumed value Je of the inertial efficiency and the presumed value rhophie of the counterelectromotive force constant, and the load disorder current ID is presumed by the difference between it and the motor current IA. A correction signal IDO is calculated by a factor 10 and a delay factor 12. A current controller 6 controls the anti-parallel 3-phase full wave rectification controller 1 in response to the deviation between the current command IP and the correction value IDO, the current detection value I. In this manner, the variation in the speed can be sufficiently suppressed to the abrupt variation in the load.

Abstract: PURPOSE:To prevent the overheat of a xenon lamp, by providing a terminal metal fitting having a sufficiently large volume as compared with the electrode rod of the xenon lamp to connect a mount means. CONSTITUTION:When the xenon lamp 1 of a photoelectric colorimeter is mounted, the terminal metal fittings 106 at both end parts thereof are engaged with position prescribing members 117 and the mount parts 110 of connection electrodes 107 are mounted on terminal pieces 112 and the mount holes 110a thereof are engaged with fixing screws 112a.

Abstract: PURPOSE: To measure the straightness of an article to be measured and the rectilinearly propagating property when manufacturing a machine by receiving interfering fringe altering upon variation of the straightness of the article by a photoelectric detector to count the degree of the fringe.  
     CONSTITUTION: Plane mirrors 4, 5 are stood on a table 8 moving rectilinearly in parallel with an ideal rectilinear line 10. The light passed through half mirrors 2, 6 of light from a light source 1 is reflected by the plane mirror 4 disposed vertically and by the half mirror 6 through lenses 9, 11, respectively into a detector 12. The light reflected on the mirror 2 is, on the other hand, reflected on the mirror 3 to pass a half mirror 7 and reflected on the plane mirror 5 vertically disposed with respect to the light, and then reflected on the mirror 7 similarly into a photodetector 12. The straightness is obtained by the optical path difference between both the lights. Since the angle between the light wavelength and the optical path is constant, the straightness can be obtained by the number of the interfering fringes.
