Title: Shape measuring instrument
Inventor: NAKAO HIDETAKA
IPC: G06T1/00
Filed: 1991-11-01
Abstract: PURPOSE:To shorten the picture processing time required for calculating the shape of an object to be measured and, at the same time, to obtain the shape diagram of the object containing no unnecessary line. CONSTITUTION:An arithmetic processing part 7 fetches input picture information stored in a memory 6 one line by one line and binarizes the information at a first threshold level. When it becomes impossible to discriminate whether or not the input image information is affected by secondary reflected light by the binarization, the part 7 binarizes the information at a second threshold level. The picture elements to be used for drawing the shape of an object to be measured are specified based on the results of the binarization. When an unnecessary line exists in the shape of the object drawn on the basis of the picture elements, the unnecessary line is deleted.

Abstract: PURPOSE:To contrive the improvement of the positioning accuracy of an electronic component to a printed circuit board when the component is subjected to surface mounting on the board. CONSTITUTION:A component 20 is mounted at a prescribed position on a board 2 coated with a soldering paste in a prescribed pattern and thereafter, this component is heated to fuse a solder and after the solder is fused, it is detected that the component is made to pass through a specified place of the region, where the component does not exist, on the printed-wiring board before the solder is again solidified. On the basis of this detection, a vibrator is brought into contact to the printed-wiring board to give a vibration to the board, whereby the acceleration of this vibration is effectively made to act on the board, the frictional resistance of the component to the board is made small and a self-alignment action is generated in a fusing between leads of the component 20 and a land of the printed-wiring board 2 by the surface tension of the solder.

Title: Automatic gain control system
Inventor: TSUDA HIROKI
IPC: H04B1/16
Filed: 1990-10-29
Abstract: PURPOSE:To set an input signal to a demodulator at a prescribed level with a small amount of controlled variable and in a short response time by setting a variable attenuator at mean quantity of attenuation during receiving a burst signal in a no signal state awaiting a transmitted burst signal, and switching an operation to automatic gain control by receiving the burst signal. CONSTITUTION:A burst signal detecting part 5 which outputs a detection signal when the burst signal is detected by receiving the output of the demodulator 1, and also, outputs a control signal to inform the reception completion of the burst signal, and a gain control means 6 which controls the variable attenuator 7 based on the output of the demodulator 1, the detection signal, and the control signal are attached. When the transmitted burst signal is awaited, the mean quantity of attenuation at the variable attenuator 7 is set so as to obtain a prescribed power for a reference input power in a state where the burst signal is received by the input of the demodulator 1. Thereby, since the automatic gain control can be started from set quantity of attenuation even when a high power arrives, a gain with prescribed level can be controlled with the controlled variable less than the one in a conventional system and in a short response time.
