Title: Method and device for blasting by coanda slit flow
Inventor: HORII KIYOYUKI
IPC: B24C1/00
Filed: 1986-04-21
Abstract: PURPOSE:To suppress wear of a pipeline and nozzle inner wall due to blasting particles by transporting the blasting particles to a slit-formed nozzle area by means of Coanda flow by air, and injecting the blasting particles from the nozzle at a high speed. CONSTITUTION:Pressurized air is sent into a pipe 2 from a slit 3 at a high speed. At the outlet from this slit 3, the air draws a stream line alpha inclined toward the pipeline 1 from the slit 2 by the Coanda effect. As a result, a negative pressure area is generated on the opposite side, and from outside, the air and blasting particles flow into this negative pressure area in the beta direction as shown by the arrow. The motion vector of the air stream from said slit 3 and the motion vector of air stream from the outside are composed to form an air stream which advances toward the pipeline 1 within the pipe. The section area of this air stream becomes smaller by an by, and the air stream is accelerated to form a dynamic boundary layer of high-speed stream in the neighborhood of the pipeline 1. The blasting particles are sent to a slit-shaped nozzle by this Coanda flow, and the blasting particles are jetted out of the nozzle outlet 22 at a high speed.

Title: Copying device for processing machine
Inventor: NABESAWA JIYUNICHI
IPC: B23K26/04
Filed: 1999-03-30
Abstract: PROBLEM TO BE SOLVED: To protect a processing machine from abnormality of bias voltage by installing a bias voltage monitoring part which monitors the bias voltage to be supplied to a distance sensor, and outputs abnormality detecting signals to a control unit when the bias voltage is deviated from a given voltage range. SOLUTION: When abnormality of a plus side bias voltage VB1, or a minus side bias voltage VB2 is reported by a bias voltage abnormality signal E12 from a bias voltage monitoring part BM, a control unit 2 directs stop of the action to a processing machine main body 3. Thereby, the processing machine main body 3 is protected so as to prevent a processing head from contacting a work and being broken. The control unit 2 monitors distance detecting signals V0 to be inputted, so as to direct stop of the action to the processing machine main body 3 even when the distance detecting signals V0 are judged as abnormal. Abnormality of the distance detecting signal V0 also means abnormality of its variation ratio. When the distance detecting signal V0 varies at high variation ratio which can not be caused in a normal action, the distance detecting signal V0 is abnormal.
