Title: Optical rotary encoder
Inventor: SATO SEIICHI
IPC: G01D5/36
Filed: 1989-10-26
Abstract: PURPOSE:To enable highly accurate detection of an angle by forming a specified light transmitting section for outputting a reference position signal of a pulse scale less in width than other light transmitting sections. CONSTITUTION:An attenuation film is formed on other slits 2 to attenuate transmitted light except for a specified slit 2a which outputs a reference position signal S2 of a pulse scale 1. Therefore, a pulse signal low in peak level which passes through the slits 2 to be an angle signal S1 is outputted while optical pulse signals high in peak level which pass through the slit 2a to be signals S1 and S2 are outputted at a fixed cycle and hence, they are outputted as optical pulse signal of one system in which signals different in intensity are mixed. The slit 2a is formed less in width than the slits 2 so that a signal wave outputted from the slit 2a has a pulse width shaped based on a reference voltage V1 of the signal S1 equal to a pulse width obtained when a signal wave outputted from the slits 2 is shaped. Thus, one cycle, 360 deg. of the scale 1 can be detected accurately.

Abstract: PURPOSE:To automate work and ensure its proper performance by making the workpiece adsorbing holder of a disconnecting robot advance and retreat horizontally, and rotate and move vertically about a vertical axis for disconnecting a workpiece. CONSTITUTION:After completion of a grinding process, grinding wheel is elevated and stopped at the specified position. Then, the arm 11 of a disconnecting robot 10 is extended so that the position of a vertical support axis 12 is made to coincide with the center of a carrier 3 and the said axis 12 is made to rotate in an arrow mark direction, thereby causing the rotation of the holder 13 of an adsorbing part about the center of the carrier 3. Consequently, a detecting pin 15 rotates coaxially and rushes into a detecting hole which is not shown herein. The pin 15 so rushed is detected by the control part. As a result, the rotation of the holder 13 is stopped, the detecting pin 15 held by a magnet 16 passes through the detecting hole and the adsorbing part 14 is positioned at a workpiece retaining hole 3. Then, the adsorbing part 14 is lowered for performing a disconnecting function. This constitution automates the disconnection of a workpiece.
