Title: Water jet nozzle
Inventor: ASO MAKOTO
IPC: B23Q11/00
Filed: 1990-11-30
Abstract: PURPOSE:To drastically restrain propagation of noise to outside by making flow velocity of air sucked into a vacuum sucking flow passage in a high- pressure high-speed air flow passage ultrasonic speed. CONSTITUTION:Big noise is generated as a water flow of high pressure and high speed collides with a substance 4 to be cut and water and powder of the substance to be cut are dissipated from the cutting point. At this time, air of high pressure and ultrasonic speed is discharged from a high-pressure high- speed air flow passage 3a at the outermost layer of a nozzle, and this air, water and the powder of the substance to be cut are sucked by a vacuum sucking source 2b through a vacuum sucking flow passage 2a. Thus, propagation of noise to outside is drastically restrained by the air flow of high pressure and ultrasonic speed, and dissipation of the powder of the substance to be cut to outside is prevented.

Abstract: PURPOSE:To prevent a solid state image pickup element from being saturated and to minimize the difference of luminance between the center and periphery of an output image by changing the distance between the aperture part of a cold shield and the photodetecting face of the image pickup element. CONSTITUTION:An electric signal outputted from the solid state image pickup element 5 is electrically processed by a processor 11 and outputted to a display device 12 and a controller 16. The controller 16 judges whether the element 5 is saturated or not based upon the electric signal.
