Title: Optical encoder
Inventor: MOMOI MOTOSHI
IPC: G01B11/26
Filed: 1992-02-27
Abstract: PURPOSE:To obtain a highly accurate angle data output at the timing of both an external period or internal period by performing prescribed correcting calculation on stored angle data when an angle data requesting signal is inputted from the outside or when the requesting signal is not inputted for a fixed period of time. CONSTITUTION:A sequence controller 11 which controls the operation sequence of each section and microprocessor which functions as a computing element 10 for calculating angle data and stores the calculated angle data are provided. When an angle data requesting signal is inputted from the outside, the microprocessor performs correcting calculation on the stored angle data based on formula I and outputs the angle data at the moment the requesting signal is received. When the requesting signal is not inputted for a fixed period of time, the microprocessor performs correcting calculation on the stored angle data based on formula II and outputs the angle data at the moment an internal timing signal is received at fixed time intervals in accordance with the internal timing signal. The thetaRES, thetaCAL, and V of the formulae respectively represent the angle (corrected) at the receiving time, angle calculated from AD data, and speed (between outside output requesting signals or variation of uncorrected angle at internal timing period). The (t), TEXT, and TIN respectively represent the time from AD data sampling to the completion of reception, outside output requesting signal period, and internal timing period.

Abstract: PURPOSE:To improve precision and product yield, to facilitate operation, and to obtain excellent weld zones by interposing an upper and a lower body to be welded between an upper and a lower electrode, and then performing resistance welding after aligning their optical axes to each other while applying pressure. CONSTITUTION:Between the upper and lower electrodes 3 and 7, the upper and lower bodies 6 and 5 to be welded are interposed and a direct current is supplied from a DC power source 10 for light to turn on a light emitting diode. Its light output is monitored on a power meter 9 and at the same time, optical axis alignment is carried out by a micrometer 4 for X and Y axis alignment to find a maximum output. In this case, the optical axis alignment is carried out while a triffle pressure of 0.1-2.0kg/cm<3> is applied. The X and Y axis alignment micrometer 4 is locked completely to eliminate deviation in main welding and a welding current and forging pressure are applied to carry out the resistance welding.
