Title: Speed reduction clutch mechanism
Inventor: OBATA MITSUYOSHI
IPC: F16H1/48
Filed: 1988-09-08
Abstract: PURPOSE:To restrain revolution error, reduce noise and improve the teaching accuracy by axially dividing a pinion formed at the end of an extension shaft, into two parts and using a resilient member between these parts to press the power transmission gear of a speed reduction gear as the parts catching the transmission gear therebetween. CONSTITUTION:The pinions 5a and 5b formed at the end of an extension shaft 2 are axially divided into two parts. The pinion 5b contains a coiled spring 6. This pinion 5b is inserted into a shaft 8. The coiled spring 6 is pressed at the specified torque as the pinions 5a and 5b catch the power transmission gear of a speed reduction gear therebetween. Said specified torque is set to a value that can drive a servo motor 11 without idling at the time of direct instruction and is lower than the torque of the servo motor 11. At the time of direct instruction teaching may be executed without backlash so that the teaching error may be reduced and at the time of playback the teaching be executed with backlash so that the operation may be done with low noise.

Title: Liquid crystal display with plural scanning lines
Inventor: YONEZU ATSUSHI
IPC: G09F9/40
Filed: 1992-07-10
Abstract: PURPOSE:To extend the resolution and the screen size of a display device by dividing a liquid crystal screen into blocks and providing plural scanning lines. CONSTITUTION:The liquid crystal screen is divided into the blocks so as to perform display. Namely, an image written in one large V(video) RAM 4 is synchronously plotted by using plural scanning lines by individual or one or more VDPs(video display processor) 3 for every block. For example, when the resolution of one block is 640X480(present representative liquid crystal display), in the case the number of blocks are 2X2 and 4X4, the resolution of 1280X960 is obtained in the case of 2X2 and the resolution of 2560X1920 is obtained in the case of 4X4. The scanning time on the screen is the same whatever extent the blocks are increased to. It is thought that plotting speed or the transferring speed of the large image becomes low by the increase of the VRAM size, but such speed depends on the performance of the CPU 2 side.

Title: Pattern matching device
Inventor: HORIE MASAHIRO
IPC: G06T7/00
Filed: 1997-08-07
Abstract: PROBLEM TO BE SOLVED: To decide the degree of matching irrelevantly to the thickness of a thin film on a substrate by performing a matching process using a template image of multi-colored lighting if a template image does not match an object image of isochromatic lighting. SOLUTION: For example, white light is used to pick up an image of an object area on a semiconductor wafer (S11). Then a pattern search for the object image is made by using a white template image Tw and the degree of matching between an image in a window set in the object image and the template image Tw is calculated (S12). Then it is judged whether or not the degree of matching is larger than a specific threshold value (S13) and when the degree of matching is less than the threshold value at all positions in the object image, a pattern search is made by using three template images Tr, Tg, and Tb picked up with red light, green light, and blue light (S14). When there are positions where the degree of matching is larger than the threshold (S15), it is judged that the position where the largest degree of matching is obtained among them is a matching position (S16).
