摘要： PROBLEM TO BE SOLVED: To ensure reliability of sealing between a hot water plug insertion port and an inserting member while improving the appearance when the hot water plug is inserted. SOLUTION: A protective cap 12 has an inserting member where an O-ring 12a is fitted in an O-ring groove 12c made in the outer circumference at a guide part 12b. An inserting part 14b is formed on the bottom face of a slide cover 14a such that a rectangle is partially deformed arcuately and the width B is set larger than the outside diameter at the guide part 12b of the protective cap 12 and slightly smaller than the outside diameter of the O-ring 12a. Consequently, the protective cap 12 is fitted in the O-ring groove 12c and the protective cap 12 is held while being inserted into the inserting part 14b. Since the O-ring 12a is not exposed to the outside, the reliability of sealing can be improved between a hot water plug insertion port and the O-ring 12a along with the appearance.

摘要： PURPOSE:To improve the performance of a magnetic shield, to enhance balance characteristics and to prevent a malfunction by setting magnetic flux density in the magnetic shield to the magnitude or less of the saturation magnetization of a magnetic shielding material. CONSTITUTION:The thickness of magnetic shielding materials 8, 9, 10 covering the inner circumference, outer circumference and side face of an annular core 2 is set in thickness, in which magnetic flux density in a magnetic shield is set to the saturation magnetization or less of the magnetic shielding materials. The thickness of the magnetic shielding material 8 arranged inside the annular core 2 is shown in formula I when a primary conductor consists of three phase and in formula II when the primary conductor is composed of single phase. Where mu0 represents the permeability (4XPIX10 (H/m)) of a vacuum, In the execution value (A) of the balance currents of the primary conductor, K the compression of the annular core and M the magnitude (T) of the saturation magnetization of the magnetic shielding material. Accordingly, magnetic flux manufactured by the primary conductor at the time of three-phase balance is interrupted sufficiently by the magnetic shield, and the output voltage of a secondary winding can be lowered, thus preventing a malfunction.

摘要： PURPOSE:To obtain a resonance frequency which is stable for temperature by using a specific magnetic resonance element in a magnetic circuit incorporating a permanent magnet and a magnetic device using a magnetic resonance element. CONSTITUTION:A magnetic device where a saturation magnetic flux density 4piMs (gauss) of a magnetic resonance element 5 and a temperature coefficient alpha (gauss/ deg.C) of the saturation magnetic flux density satisfy an expression I is formed, where f0 is a resonance frequency at a reference temperature of a magnetic device, delta is a temperature coefficient of a permanent magnet 2, gamma is a magnetic rotation ratio of the magnetic resonance element 5, N is a diamagnetic field coefficient of the magnetic resonance element, and 4piMsO is the saturation magnetic flux density at the reference temperature of the magnetic resonance element. By replacing an iron element by another element, 4piMsO and alpha are varied. The 4piMs0 and alpha satisfy a relationship shown by an expression II. C and d are determined by a replacement element. Since the expressions I and II are straight lines with a different inclination, a magnetic resonance element retaining a relationship of cross points at the expressions I and II can be selected and the magnetic device using a static magnetic wave can obtain a stable resonance frequency for temperature.
