Title: Automatic focusing device
Inventor: YUI TAKASUMI
IPC: H01L21/027
Filed: 1985-06-18
Abstract: PURPOSE:To enhance the final positioning precision by a method wherein the initial setting of the fine movement system is executed before a measurement of the distance between the projection optical system and such a tabular object as a wafer, which is conducted before an exposure is performed. CONSTITUTION:The round number DELTAD0 of the drive amount of the Z stage is obtained by measuring the distance between the projection optical system and the wafer using a nozzle 12 and a reserve drive amount DELTAd0 is computed from the DELTAD0. The reserve driving is a fact that the Z stage is made to drive as much as the DELTAd0 during the time of step-feed of the wafer stage and the wafer stage is set up in advance in the vicinity of the center of the driving range of a piezo 5 in such a way that the piezo 5 alone has only to drive. For computing the DELTAd0 from the DELTAD0, an amount of DELTAZ is taken into considera tion and the DELTA0 is decided in such a way as to satisfy 1DELTAD0-DELTAd01<=P/2. Here the P is the minimum driving resolution of a pulse motor 3, which is used as the coarse movement system, and the reserve drive amount delta0 is a drive amount which is driven by the coarse movement system. In reality, a number P0 of driving pulses, which corresponds to the DELTAd0, is given to the pulse motor.

Abstract: PURPOSE:To enable steel sheets to be skewed easily and always exactly, by a method wherein relative angles between each slot and central slot notch of the steel sheets are shifted sheet by sheet in forming order. CONSTITUTION:When steel sheets 1 for a rotor are formed by press dieing out, the sheets are died out one by one shifting the direction of notches 2a at an angle theta by theta. Then, the died out steel sheets 1 are laminated to be fitted on a shaft 4 for die casting through the central slots 2 of the sheets in the dieing-out order. As the result, each steel sheet 1 of the laminated product 10 is arranged to be positioned by being shifted in the circumferential direction from the position of the slot 3 of the steel sheet 1 put lower in order according to the angle theta and is automatically skewed in a given form.

Title: Manufacture of film
Inventor: KIMURA TAKEHIKO
IPC: B29C47/88
Filed: 1979-10-12
Abstract: PURPOSE: To improve separation property from a film and to enhance a cooling property of the film, by a method wherein a plasticized thermoplastic resin film is supported by a double-bleached kraft paper having a surface weight of 50W100g/ cm 2  for cooling.  
     CONSTITUTION: Thermoplastic resin is molded into a thermoplastic film 2 by means of a film molding device 1, and the film is continuously fed to a cooling roll 3. In the meantime, the cooling roll 3 feeds a double-bleached kraft paper 4 having a surface weight of 50W100g/cm 2  continuously, and the kraft paper supports the film 2 in such a manner as causes the film to be adhered to the kraft paper. The film is rolled around a winding roll 5 as it is cooled. After the film 2 ceases to show blocking or viscosity resulting from a proper aging process, the film 2 is separated from the kraft paper 4 for winding. This causes the improvement of cutting and perforating and prevents the film from curling when the film is separated from a support material.
