摘要： PROBLEM TO BE SOLVED: To provide revolutions sensor is which the high accuracy of the circularity on the outside face of a base body is not required and which is manufactured easily. SOLUTION: Three ribs 14 which protrude to the inside are installed at the inside face which is close to the inside bottom face of a bottomed cylindrical case 11. When a magnet 16, a pair of magnetoresistance elements 17 and a column-shaped base body 15 at which a processing circuit 18 is installed are housed inside the bottomed cylindrical case 11, the three ribs 14 are deformed, and the base body 15 is fixed inside the bottomed cylindrical case 11. By this constitution, when the height of the three ribs 14 inside the case 11 is formed with good accuracy, the position of the magnetoresistance elements 17 can be regulated precisely. Then, since the height of the three ribs 14 can be adjusted easily, the high accuracy of the roundness on the outside face of the column-shaped base body 15 is not required. As a result, an excellent effect to easily manufacture the revolutions sensor is obtained.

摘要： PROBLEM TO BE SOLVED: To prevent the short circuits between output terminals and leaking current and to eliminate the pressure control step when a semiconductor magnetic detecting element and a bias magnet are fixed, by securing the insulation between the semiconductor magnetic detecting element and the surface of the bias magnet. SOLUTION: The semiconductor magnetic detecting element 3 is mounted on a TAB film 2 and fixed to the surface of a bias magnet 1 with a bonding agent 4. By providing a tape 5 between the semiconductor magnetic detecting element 3 and the bias magnet 1, the semiconductor magnetic detecting element 3 can hold the specified interval for the surface of the bias magnet, and insulation is secured. Thus, the short circuits between the output terminals through the bias magnet 1 of the semiconductor magnetic detecting element 3, the prevention of the leaking current and the pressure control, when the semiconductor magnetic detecting element 3 is attached, are not required.

摘要： PROBLEM TO BE SOLVED: To provide a vacuum cleaner whose dust collecting efficiency is improved sufficiently by taking suction from a different part even when a paper bag is fitted closely to the whole lattice plane of a suction air lattice body having a dust collecting filter. SOLUTION: In the suction air lattice body 13 having the dust collecting filter 24, suction air can flow into the suction air lattice body 13 nearly from a horizontal direction. Thus, even when the paper bag is fitted closely to the whole lattice plane of the suction air lattice body 13, the suction air nearly in the horizontal direction flows into the suction air lattice body 13, suction is performed until the paper bag is fully expanded.

摘要： PROBLEM TO BE SOLVED: To provide an electric vacuum cleaner easy to use, due to the plug position where the plug can be easily pulled out for use and its metal part dose not contact and damage the floor in storage. SOLUTION: The body 5 of this cleaner, which looks like a track shape seen from the above, is equipped with a wheel 20 on both sides. Also the line core take-up reel 21 is horizontally installed above an electric blower 21. Since there is an opening 26 for pulling out the line cord so that the plug 30 can be stored in the space above the wheel, the metal part of the plug 30 hardly contacts and damages the floor when stored and the plug 30 can be easily taken to pull the line cord, thus improving the usability.

摘要： PROBLEM TO BE SOLVED: To enhance quality by enhancing the strength of the bottom face of a dust chamber; to achieve reduction in weight by thinning the large bottom face of the dust chamber; to enhance serviceability by preventing a decrease in amount of air fed by a motor-driven fan, up to a maximum capacity for dust; and to enhance design by storing attachments at the bottom face of the dust chamber which cannot be viewed under normal use conditions. SOLUTION: A dust chamber wall 6 and a partition wall 5 are interconnected by an attaching part 9 for a caster 19 and by a casing 14 to form a spinal beam condition on the bottom face of a dust chamber to thereby enhance strength. The strength enhanced by this beam arrangement allows thinning of the bottom face of the dust chamber other than the attaching part 9 and the casing 14. Thus, the strength is enhanced and a reduction in weight is achieved.
