IPC: H01H71/74
Filed: 1992-07-23
Abstract: PURPOSE:To simplify the adjusting process for an input signal to a circuit breaker and shorten the adjusting time. CONSTITUTION:An accidental current flowing in an AC electric path 10 is sensed by a current sensor means 401 at certain intervals. The secondary output level of this sensor means 401 is judged by a level judging means 402, and the difference between this secondary output level and the reference level accommodated in a memory means 190 is calculated by a processing means 200b.

Title: Throw-away type roll cutting tool
Inventor: TSUJIMURA OSAMU
IPC: B23C5/10
Filed: 1986-08-22
Abstract: PURPOSE:To enhance the quality of a finished surface by changing the circumferential direction spacing between a throw-away chip cutting edge fitted in a groove set with different twisting angle and a chip cutting edge of the adjoning groove, and by preventing minor amplitude vibrations generated by resonance of the tool body. CONSTITUTION:The twisting angle theta1 of grooves 12, 14 is given a smaller value than the twisting angle theta2 of grooves 13, 15, so that the circumferential direction spacings between the grooves 12 and 13 and between ones 14 and 15 become wider toward the base end of the end-mill body 11, while the spacings between grooves 13 and 14 and between 15 and 12 become narrower. Accordingly the frequency of micro-amplitude vibrations generated by machining of a work on a throw-away chip 5 fitted along said groove 15 to each groove 12 will vary in the axial direction. Therefore, the vibration generated by the end-mill body 11 due to machining of chip...5 becomes irregular in the axial direction, whereby generation of resonance can be suppressed, which might cause breakage to the cutting edge 7 on the body 11 or deteriorate the finished surface roughness on the work processed.

Filed: 1986-08-25
Abstract: PURPOSE:To enable accurate detection of defective coating of a primer without being affected by the base color of a work by binary coding an image screen by using the threshold value corresponding to the base color of the work. CONSTITUTION:The coating surface of the work on which the primer is coated is taken as an image by a visual sensor 15 and the presence or absence of the defective primer coating is detected in accordance with the image.
