IPC: G03F9/00
Filed: 1988-04-25
Abstract: PURPOSE:To eliminate the production of an offset by the astigmatism of a projecting lens and precisely detect a focal point position by determining a focal point position of the position from the focal point position of an S direction and an M direction. CONSTITUTION:A second focal point position detecting system 26 has detectors 26a, 26b for receiving two divided parts of light respectively and the focal point positions of the S direction and the M direction are detected by the use of a mark extending in the X axis direction. A memory 28 as a fluctuating characteristic storing means previously stores the fluctuating characteristics of the focal point position at a plurality of points in an image-formation produced according to the quantity of accumulated heat quantity for a projecting lens 6 of irradiating energy calculated from the output signals of a detector 12 and the closing time and the opening time of a shutter. A main control device 30 calculates the condition of the image-formation of the lens 6 and controls the surface position of a wafer W for the image-formation surface in response to the condition of its image-formation surface. Thereby, the focal point positions are detected precisely.

Title: Sampled value pid controller
Inventor: ICHIKAWA YOSHINORI
IPC: G05B21/02
Filed: 1982-06-16
Abstract: PURPOSE:To eliminate the need for a monitoring person or expensive monitoring facilities by providing a sampled value PID controller with a characteristic variation detection part which detects the characteristic variation of a process and monitoring the characteristic variation of the process on on-line basis. CONSTITUTION:If the characteristic variation of the plant occurs during operation, a direct current for a model error is generated. When the balancing point of the process varies, the direct current for the model error is generated as well. For this purpose, the characteristic variation of the process and the variation of only the balancing point of the process are discriminated in case of the occurrence of the model error. When there is the characteristic variation of the process, a command value is varied impulsively to caluse large variation in model error and when only the balancing point of the process is varied, there is no variation, so a characteristic variation detection part 13 computes the model error to vary the command value impulsively when there is the direct current, checking whether the model error varies greatly or not at this time. When it varies greatly, automatic tuning is carried out. When not, the automatic tuning is not carried out.

Abstract: PURPOSE:To obtain a clear image with a reduced measuring time by indentifying detectors for detecting two gamma rays released in the opposite direction to measure a difference of the detection time, from which the gamma ray generating position on the straight line is determined. CONSTITUTION:Unit numbers (i) and (j) of detectors Ai and Bj which detected two gamma rays released in the direction of 180 deg. opposite to each other are memorized temporarily into a temporary memory 7 and outputted to an arithmetic device 12 by a trigger signal from a timer 11.

A signal passing through 6 groups of time signal generators 9 is used as stop signal for the timer 11 once delayed by a specified times DELTATd with a delay line 10. An arithmetic unit 12 stores DELTAt' outputted from the timer 11 and numbers (i) and (j) of detectors outputted from the temporary memory 7 into a memory section. Then, an actual time difference DELTAt is determined to calculate the gamma ray generating position.

Title: Webbing winding device
Inventor: ASAGIRI YOSHINORI
IPC: B60R22/38
Filed: 1999-04-09
Abstract: PROBLEM TO BE SOLVED: To achieve weight reduction while ensuring locking strength. SOLUTION: A single locking plate 42 while meshes with an internally toothed ratchet 38 during sudden deceleration of a vehicle is held in a storage part 40 formed in the holding part 24C of a base lock 24. During sudden deceleration of the vehicle, the lock plate 42 guided by a guide hole 50 in a V-gear 46 is moved approximately radially outwards and engages the internally toothed ratchet 38. The opposite side of the holding part 24C of the base lock 24 is press contacted against the internally toothed ratchet 38 by means of a reaction force generated and is plastically deformed for engagement. Thus, locking with the internally toothed ratchet 38 can be achieved at two radially opposite portions, and since the locking plate 42 used is formed as one plate, weight reduction can be achieved while locking strength is ensured.
