Title: Positioning device
Inventor: FUKUDA MAKOTO
IPC: H01L21/027
Filed: 1992-02-18
Abstract: PURPOSE:To secure the following-up ability of a target value as well while suppressing the influence of disturbance by adding the feedforwards of differentiated amounts from the first time to the third time of a target position as control elements. CONSTITUTION:A target position generation part 6 gives the target position of a stage 25. A position control part 27 calculates position deviation between this target position and the feedback amount, calculates a PID output corresponding to the proportional amount, integrated amount and differentiated amount in respect to this deviation and obtains a control output by adding the respective differentiated amounts of the target position to this PID output. A feedback element F1 calculates the proportional amount, integrated amount and differentiated amount of the position deviation, and a feedforward element F2 calculates an amount in proportion to the differentiated amounts from the first time to the third time of the target position. An adding means Ad adds the amounts calculated by these elements F1 and F2. Namely, in addition to the PID control element of a cyclic transmission function, the feedforward amount of the target position is added to the control element. Thus, the following-up ability of the target value can be compatible with the stability to disturbance.

Filed: 1988-03-17
Abstract: PURPOSE:To efficiently use a bus when difference between time required for producing data and the period of data transfer is large by reading out data corresponding to a transferred address out of the data accumulated in a data accumulating means. CONSTITUTION:When the time required for producing data is shorter than the time required for generating an address, namely, the time required for actually transferring the data, data produced in a short time are transferred independently from the address by a high-speed data transferring means 1 at high speed and accumulated in a data accumulating means 2. On the other hand, the address is transferred at timing which is independent from the data transfer timing by means of an address transfer means 3. An accumulated data reading-out means 4 reads out data corresponding to transferred addresses out of the data accumulated in the data accumulating means 2 every time when the addresses are transferred.

Abstract: PURPOSE:To prevent the lowering in the capacity of an auxiliary linear light blocking body, by supplying a current to the auxiliary linear light blocking body from a power source prior to the detection operation of a pattern to be detected and burning off the dust adhered to the auxiliary linear light blocking body. CONSTITUTION:Prior to a detection operation, a power source 13 is turned ON to supply a current to an auxiliary linear light blocking body 4 and said light blocking body 4 is brought to a hot-red state to burn off the dust adhered thereto. By this preparatory operation, the light blocking body 4 becomes a harmless one generating no reflection since the dust is removed or said light blocking body becomes a black opaque body. As a result, pattern omission is eliminated and a protruding part caused by reflected light due to dust is not generated in the wave form of a detection signal. An ideal black line region 6 is obtained by the cooperation of a linear light blocking body 2 and the auxiliary linear light blocking body 4 and the adverse effect of the light from the circumferential bright part 5 is not received.
