Title: Hydraulic controller for industrial vehicle
Inventor: MAKI KUNIO
IPC: B66F9/22
Filed: 1997-03-25
Abstract: PROBLEM TO BE SOLVED: To enhance the accuracy of stopping a moving element in a predetermined position by making the function of the stopping accuracy as little as possible. SOLUTION: A central processing unit(CPU), in a low-speed control routine in which the tilt cylinder of a forklift is controlled to become horizontal, computes the deviation Δs between the tilt angle s1 of the previous control and the current tilt angle (s) (S20). It then determines whether or not the deviation Δs is within a predetermined range (S30, S40). If a lower limit value Δs min >= deviation Δs, a corrected count C is incremented by five (S50); if deviation Δs>=Δs max, the corrected count C is decremented by ten (S60), and then the aperture A to be controlled this time is calculated on the basis of the corrected count C (S70).

Filed: 1993-03-30
Abstract: PURPOSE:To realize a diffraction grating having two uniform diffraction grating patterns in two regions on the surface of a semiconductor substrate by exposing one photoresist layer to an electron beam while the other photoresist layer to ultraviolet rays. CONSTITUTION:A photosensitive photoresist layer 2 is formed on a semiconductor substrate 1 and a photoresist layer 3 sensitive to electron beam is formed thereon.

Title: Semiconductor substrate organic processing apparatus
Inventor: SARUWATARI SHINSUI
IPC: H01L21/027
Filed: 1982-04-30
Abstract: PURPOSE:To control vapor concentration within the processing chamber by providing a vapor concentration control mechanism such as damper within the processing chamber and also by opening or closing it as required. CONSTITUTION:Vapor concentration at the time of processing semiconductor substrate 5 is changed by opening or closing a damper 8 with an adequate means. Namely, when perfectly saturated vapor atmosphere is requied, the damper 8 is perfectly closed making zero the opening area of exhaust duct 7. On the contrary, when the minimum vapor concentration is required, the damper 8 is fully opened making maximum the opening area of exhaust duct 7 and the vapor concentration in the processing chamber is controlled. The amount of vapor exhausted from the processing chamber is adjusted by such vapor concentration control mechanism as mentioned above. Accordingly, the optimum vapor concentration is set for each type of semiconductor substrate 5 and the surface of semiconductor substrate 5 can be processed in the optimum condition, thereby improving the production yield. Moreover the damper 8 is fully opened during the non-processing period for obtaining the maximum opening area. Thereby, the vapor concentration is minimized and the diffusion to the outside of the apparatuses of the vapor generated while the upper cover 1 is opened or closed can be minimized, thus contributing to the safe and sanitary operation.
