Title: Control of pen pressure in automatic drafting machine
Inventor: FUJITA JOJI
IPC: B43L13/00
Filed: 1988-02-26
Abstract: PURPOSE:To prevent ununiformity in line quality from being generated, by a method wherein the pressure with which a writing implement held by a pen holder is pressed against a paper support surface is varied according to variations in the velocity of a head relative to the paper support surface. CONSTITUTION:A lifting driver 8 is attached to a head 4, and a pen holder 12 for holding a writing implement 10 is connected to an output shaft of the driver 8. A controller judges whether the pen holder 12 is in a pen-up position or in a pen-down position, and when the pen holder 12 is in the pen-down position, the controller judges whether a specified pen pressure is greater than a prescribed pen pressure. When the specified pen pressure is greater than the prescribed pen pressure, the resultant velocity of a head 4 is obtained from rotating speeds of X- and Y-motors 26, 28. It is judged whether the resultant velocity of the head 4 is brought to a decelerating point, and when the resultant velocity is not yet brought to the decelerating point, the rate of increase in pen pressure is obtained from a maximum velocity of the head currently specified and the current resultant velocity of the head. A value obtained by adding the increase in the pen pressure to the prescribed pen pressure is supplied to a digital-analog converter in the controller, and an analog voltage output is supplied to a driver 8, whereby the pen pressure is increased in proportion to the velocity.

Abstract: PURPOSE:To provide a stepper which can increase the alignment accuracy of an original picture pattern drawn on a reticle. CONSTITUTION:For alignment of an original picture pattern drawn on a reticle 2, the first thing to do is to drive a motor 18 for moving a reticle stage 16.

A pattern recognizing section 42 recognizes an edge of the original picture pattern from a change in the state of the laser light which enters a detector 24. A controlling section 46 converts the information about the edge of the original picture pattern into the locational information based on the number of rotations of the motor 18 and calculates the rotational deviation angle of the original picture pattern from an orientation flat of a wafer 4 and the location of the center of the original picture pattern and then conducts an alignment of the original picture pattern.

Title: Method and device for scaling up image
Inventor: EGLIT ALEXANDER J
IPC: H04N5/262
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To provide an up scaler which generates a destination image by scaling up a source image without the need to maintain the aspect ratio (ratio of the length and width of the source image) of the source image. SOLUTION: The source image data are received at a 1st clock rate and the destination image is generated at a 2nd clock rate. The 2nd clock rate is so calculated that a frame rate at which the source image is received becomes equal to a frame rate at which a scaled-up image is generated. For this clock rate, the up scaler 100 can be actualized by using only one line buffer to scale up the source image. A conventional system requires a large-capacity memory such as a frame buffer so as to obtain a similar function.

     CONSTITUTION: A film 6 of MgF 2  or the like having a thickness of approx. 1400Å and functioning as a non-reflective film and an interference film is formed on a cover glass 5. A film of Cr or the like having a thickness of approx. 800Å is then formed as a reflective film 7 on the portion A coated with color by a mask evaporating process, or a reflective film 7 is formed on the entire film 6 and the reflective film 7 is photoetched on the portion corresponding to the non-reflective portion B. Thus, the film 6 operates as an interference film on the portion where the film 7 is existed and as an non-reflective film on the portion where the film 7 is not existed. There is only one layer or film of evaporated mask, which is not introduced into the non-reflective portion, resulting in the production of a beautiful boundary therebetween. The cover glass is not contaminated at etching time to improve the yield of the watch.
