Title: Rotational magnetic field type magnetic flaw detection
Inventor: TAKAHASHI MICHIAKI
IPC: G01N27/83
Filed: 1985-11-22
Abstract: PURPOSE:To enable the detection of a surface flaw over the entire circumference of a steel material, by detecting a leakage magnetic flux generated by a rotary magnetic field along the sectional circumference of the steel material. CONSTITUTION:A low-frequency three-phase AC power source 11 at a transmission circuit (B) generates an alternating current determining the revolutions of a magnetic field and a high frequency AC power source 12 does an alternating current as flaw detection frequency. then, the three-phase AC synthesized with a waveform synthesizer 13 is amplified 14 in the power to be applied to an exciting coil 10. At a detector section (A), a high frequency AC as flaw detection frequency rotates at the number of poles determined by the way of winding a coil 10 and at revolutions determined by the frequency of a low frequency three-phase AC. A leakage magnetic flux induced in the surface of a steel material 1 is detected by switching detection elements 8a-8c,... arranged in the circumferential direction of the steel material with a switching circuit 15 at a timing synchronizing the revolutions of a rotary magnetic field to be created by a synchronous control section 18 at a receiving circuit (C). After being differentially amplified 16, the presence of a surface flaw is judged to be outputted to a recorder 17.

Title: Lid for sealed container
Inventor: EZAKI KENJI
IPC: B65D43/10
Filed: 1996-09-12
Abstract: PROBLEM TO BE SOLVED: To reduce force required for fitting a lid over a container main body and facilitate the placing of the lid over it, by disposing a guide taper rib formed so that the front end of an engagement projection or the vicinity of the front end and the inner surface of the vertical wall of a fitting part are connected to each other. SOLUTION: A guide taper rib 5 is formed so that the front end 2c of an engagement projection 2 or the vicinity of it and a specific point 1a' on the inner surface of a vertical wall 1a outside a fitting part 1' which is situated lower than the lower end 2d of the engagement projection 2 are connected to each other. Thus, an inclination angle β formed between the perpendicular line of the guide taper rib 5 and it is made smaller than an inclination angle α formed between the perpendicular line of the lower face 2b of the engagement projection 2 and it.  When the angular part 3a' of the upper part of a ringlike bulge 3a in a container main body 3 is guided to the guide taper rib 5, it does not come into contact with the lower face 2b of the engagement projection 2, therefore this reduces resisting force exerted when the ringlike bulge 3a slides over the engagement projection 2, that is, force with which the lid 1 is fitted over the container main body 3. Thus, the placing of the lid 1 over the container main body 3 is facilitated.
