    Abstract: A strain sensor includes a cylindrical strain body extending in an axial direction, a first fixed part, a second fixed part, and a strain detection element. The first fixed part is connected to the strain body at a first connection part and extends from an opening of a first end of the strain body in the axial direction. The second fixed part is connected to the strain body at a second connection part and extends from an opening of a second end of the strain body in a direction opposite to the first fixed part with a gap interposed between the strain body and the second fixed part. The strain detection element is disposed such that a center of the strain detection element is closer to the second fixed part than a center of the gap in the axial direction.

  • Patent number: 8569635
    Abstract: A weight sensor includes a deformable body, a first strain resistor provided on an outer side surface of the deformable body, and a pressing member applying a load to the deformable body. The deformable body includes a tubular portion having a tubular shape extending along a center axis and surrounding the center axis, and a projection projecting from an inner surface of the tubular portion. The pressing member moves along the center axis so as to apply a moment to the tubular portion. The resistances of the strain resistors change greatly, allowing the weight sensor to measure a load with high sensitivity.

  • Patent number: 7836774
    Abstract: It is aimed to provide a strain detector having a fewer number of mounting parts and high operation efficiency and usability. The strain detector is provided with a cylindrical strain generator to be strained upon receiving a load, a resistor element which is arranged on the outer circumferential surface of the strain generator and whose resistance varies depending on the amount of strain, a signal processing circuit connected with the resistor element and screw portions arranged above and below the strain generator to sandwich the strain generator. The strain generator and the screw portions are integrated.

  • Patent number: 7306640
    Abstract: A vacuum cleaner includes a first dirt separation unit and a second dirt separation unit. The first dirt separation unit has a first inlet port through which a suction air stream including dirt particles is introduced thereinto, and the second dirt separation unit has a second inlet port through which the air stream introduced into the first dirt separation unit is introduced into the second dirt separation. The first and the second inlet port are disposed such that they are not registered with each other. Accordingly, the dirt particles suctioned are separated in two stages, thereby decreasing the possibility of occlusion of a filter and rapid deterioration of a suction force.
