Abstract: PURPOSE:To ensure improved smoldering resistance of an ignition plug by carrying out metal plating or formation treatment at a point opposing the outer surface of a porcelain insulator which retains a central electrode within the inner surface of a main fitting which retains a grounding pole. CONSTITUTION:A porcelain insulator 1 retains a central electrode 2 at its tip and is fixedly contained in the containing hole 4 of an iron-made main fitting 3 which retains a grounding electrode 6. A clearance 5 is formed between the outer peripheral surface 1a of the porcelain insulator 1 and the inner peripheral surface 3a of the main fitting 3. Metal plating of 5mum or more in thickness with the use of chromium, zinc, gold, etc., or formation treatment such as phosphate treatment and chromate treatment, or both of metal plating and formation treatment are carried out on the inner peripheral surface 3a. This arrangement suppresses the elution of an Fe ion catalyst which graphitizes carbon adhering to the inner peripheral surface 3a at 500-600 deg.C, contributing to improved smoldering resistance of a plug and its increased durability.

Abstract: PURPOSE:To change a reference value to a proper value according to the conditional change with the lapse of time by resetting the reference value to discriminate between galvanized sheet iron and common steel sheet for each time of performing predetermined number of discrimination. CONSTITUTION:A measured value group including a measured value of reflected light of the steel sheet is stored and a value not included in the limits of an error expected based on the stored measured value group is set as the reference value by a reference value setting means. Then, the discrimination between the galvanized sheet iron and the common steel sheet is performed by the result whether the measured value of the reflected light on the surface of the sheet iron to be discriminated is smaller or larger than the set reference value by a discriminating means. The reference value is changed to the proper value by resetting the new reference value based on the renewed measured value group by the reference value setting means for each time of performing predetermined number of discrimination. Thus, the accurate discrimination can be performed in using extending the long period.

Abstract: PROBLEM TO BE SOLVED: To effectively cope with deterioration of catching efficiency of metal powder due to the turbulence of treating liquid and a reduction in contact time. SOLUTION: An inflow port 11 provided at one end of a treating tank 10 has an opening at the bottom part of a receiver 13 attached to the treating tank 10. In the treating tank 10, a magnetic drum 14 with a built-in a magnet is longitudinally arranged with its axis being along the flow direction A of treating liquid L toward an outflow port 12 provided at the other end of treating liquid L. Compared with the existing device having the magnet drum transversely arranged to the flow direction A of treating liquid L, impingement area of the magnet drum 14 to the treating liquid L flowing into the treating tank 10 from the inflow port 11 is reduced, the occurrences of turbulence is restrained, and the treating liquid L flows along the peripheral surface of the magnet drum 14 in the axial direction, thereby extending contact time of the treating liquid L and the magnetic drum 14 to improve catching efficiency of metal powder M than before.

Abstract: PURPOSE:To perform a job for compensation to define the bristle length of a brush automatically as well as to stabilize the degree of deburring quality by installing a measuring plate, retracting as pushing by the brush going forward together with a spindle, and a probe, coming into contact with this measuring plate and outputting a contact signal, both in and around an engaging member. CONSTITUTION:A brush holder 21 is attached to a spindle of a burring machine body, and a holding plate 22 is attached to this holder 21 shiftably in the axial direction. An engaging recess 32 fittable in an engaging projection 26 at one end of a screw shaft 24 is installed in the upper end of an engaging member 33 set up in a moving range of this spindle. In a state that the engaging projection part 26 and the engaging recess 32 are engaged with each other and thereby rotation of the screw shaft 24 is regulated, the spindle is rotated and the screw shaft 24 is screwed in the brush holder 21, while the spindle is advanced forward as far as a portion for this screwed variable, having a position of the plate 22 remained unchanged, and a brush 20 is projected out of the holding plate 22. With this projected brush 20, the measuring plate 37 is depressed till it reaches a probe 40, thus each bristle length is kept constant.
