Title: Cutting oil splash prevention device for wire-cut spark erosion machine
Inventor: YATOMI TAKESHI
IPC: B23H7/02
Filed: 1981-01-12
Abstract: PURPOSE:To prevent cutting oil from splashing by installing a cylindrical protector, that is movable up and down, around the nozzle through which the cutting oil is supplied to the location of the wire-cut spark erosion machining. CONSTITUTION:The cutting oil is supplied to the working location of the wire- cut spark erosion machining through a nozzle 14. A cylindrical protector 17 is installed freely slidable up and down by means of lengthy holes 18 and fixing screws 19. The cylinder 17 is always brought down by its own weight to touch the work 12, but at the same time lifted up slightly due to the pressure of cutting oil splashing to transverse directions. The pressure of cutting oil also acts on the gap between the top end of the cylinder 17 and the nozzle 14, and the cylinder status at a position of balance of these forces. Splashing of the cutting oil coming out of the bottom end of the cylinder is prevented due to viscous damping provided by the cutting oil falling down from the top end of the cylinder.

Title: Method for detecting leakage of liquid
Inventor: MUKAI YUUJI
IPC: G01M3/20
Filed: 1983-01-13
Abstract: PURPOSE:To ensure quick detection of leakage, by deforming the side wall of a flexible container, which is filled with a coloring liquid and whose opening part is tightly sealed by a plug, by a constant pressure compressing mechanism, absorbing the coloring liquid, which leaks when the sealing is poor, by filtering paper, and detecting the defect by a photoelectric switch. CONSTITUTION:A flexible container 3 is filled with a coloring liquid L such as ink and sequentially conveyed to a detecting position by a holding member 2, which is arranged on the same circumference of a turntable 1. An opening part of the container 3, which is tightly sealed by a plug 31, is coupled into a guide hole 41 of a guide plate 4 of a detecting part. Filtering paper 5 is sent to the guiding hole 41 by a winding mechanism and made to contact with the tightly sealed part of the container 3. A photoelectric switch 6 is provided at a certain angle above the guiding hole 41. A light beam is rotated around the periphery of the opening part of the container by the action of a motor 7 and projected on the periphery. When the filtering paper 5 is colored by the leaked liquid, reflectivity is decreased, and measurement is performed based on this fact. Then, a constant pressure compressing mechanism 8 is moved to the side of the holding tool 2 and the container 3 is pushed and deformed. When the sealing by the plug 31 is incomplete, the filtering paper is colored by the leaked liquid, and this event can be positively detected.
