Title: Method and circuit for detecting rotor position of brushless motor
Inventor: YAMAMOTO HIROYUKI
IPC: H02P6/18
Filed: 1993-08-17
Abstract: PURPOSE:To reduce the number of signal lines by a method wherein a frequency signal is integrated using a spike voltage such as the rise of the voltage applied to an armature winding as a reference and a maximum voltage value of the integrated signal is calculated and divided into the specified number of parts and then the position detecting signal of a rotor is obtained by comparing the divided voltage values and the integrated signal. CONSTITUTION:A basic frequency detecting section 12 detects a frequency with a spike voltage contained in terminal voltage U out of the terminal voltages U, V and W of an armature winding. An integrating section 13 detects one cycle of the detected frequency signal and integrates the signal for one cycle. The operation of the integrating section 13 is reset by a resetting section 16 and the detected frequency signal is integrated for one cycle. A comparing section 14 detects a maximum value of the integrated signal output from the integrating section 13 and equally divides the maximum voltage value into six and detects a timing of each of the divided voltage values at the time of division. A comparison result signal combining section 16 combines input signals from the comparing section 16 and outputs position detection signals Ua, Va, and Wa which are a specified phase behind.

Title: Monitor method for working range of articulated type robot
Inventor: SHINDO AKIO
IPC: G05B19/19
Filed: 1984-10-26
Abstract: PURPOSE:To attain the effective use of a space outside a working range of a articulated type robot with no malfunction by using the software for minitor of the working range of the robot. CONSTITUTION:A resistance divider 1 is attached to a articulation of a robot so as to secure the 1:1 correspondence between the articulation position and the output voltage value of the divider 1. Then the output voltage of the divider 1 is converted by N times through an A/D converter 2 is order to delete the effects of disturbance. Then this converted voltage undergoes an averaging process through the software to obtain the mean value. This mean value is held in a memory element 3 and then compared with the data on the working range of the robot stored in a memory element 4. Then the out-of-range processing is carried out if said mean value is out of the robot working range. When said working range is changed, both the upper and lower limit values of the angle needed for actions of the robot are supplied in the form of angles through a keyboard 5 of a controller. These angle values are converted into the output voltage of the divider 1 according to an input angle and stored to the element 4.

Filed: 1995-08-09
Abstract: PROBLEM TO BE SOLVED: To provide a method by which a wiring layer which can suppress the occurrence of disconnection and short circuits can be formed through a simple process. SOLUTION: After a composition-modulated layer is formed on a substrate, a resist layer R13 is formed in a prescribed pattern. When the part of the composition-modulated layer which is not covered with the layer R13 is etched with an etchant, a wiring layer 15 is obtained. When a layer containing copper and chromium in such a state that the coppercontent varies from 100% at the upper surface to 0% at the lower surface and the chromium content varies from 0% at the upper surface to 100% at the lower surface (namely, copper becomes dominant as going toward the upper surface and chromium becomes dominant as going toward the lower surface) is used as the composition- modulated layer and such an etchant that the etch rate to copper is higher than that to chromium is used, the upper surface of the wiring layer 51 can be curved and steps can be smoothed. Therefore, the occurrence of disconnection and short circuits in another wiring layer overpassing the wiring layer 51 can be prevented.

Filed: 1989-08-29
Abstract: PURPOSE:To completely remove astigmatism and further to reduce cost while easing the work accuracy of a light element by setting the astigmatism of a light flux in a position out of an optical anamophic optical system to an amount to cancel the astigmatism to be generated in the optical system in a rear step by adjusting an internal between a light source and a collimator optics. CONSTITUTION:In the optical system in the rear step rather than an anamorphic prism 13, a fixed mirror 15, beam splitter 20, movable mirror 16 and objective lens 17 are arranged. The astigmatism to be generated in these optical systems in the rear step is canceled with the astigmatism in the position out of the anamorphic prism 13 by adjusting the interval Z between a laser diode 11 and a collimator lens 12 and the astigmatism of the light flux to be converged to a magnetooptical disk 1 is corrected to zero. Thus, since the astigmatism is removed on the storing medium, the manufacture cost can be reduced by easing the work accuracy of each optical element in the optical system in the rear step.
