  • Patent number: 10615675
    Abstract: A stator unit included in a motor includes a base member, an armature, a circuit board, and a mold resin portion. The base member extends substantially perpendicularly to a vertically extending center axis. The armature and the circuit board are positioned above the base member. The circuit board is electrically connected to the armature. The mold resin portion covers the armature and the circuit board. In a process of forming the mold resin portion, the base member is supported by a first mold. Then, the first mold is joined to a second mold such that a cavity is provided therebetween. In this step, the second mold is pressed against a projection provided on an upper surface of the base member and on a radially outer side with respect to the circuit board in plan view. The projection thus pressed is squashed. Subsequently, molten resin is injected into the cavity.

  • Patent number: 10458816
    Abstract: A sensor includes an electrode, an insulator, a pressure receiver, and a pressure imparting unit. The insulator is disposed at a position facing the electrode and away from the electrode. The pressure receiver is disposed on a surface of the insulator on a side opposite to the electrode. The pressure imparting unit presses a part of the insulator toward the electrode at a position different from the pressure receiver to contact the insulator with the electrode. The insulator generates power by contact charging or separation charging with respect to the electrode, to output the power as a signal.

  • Patent number: 10298150
    Abstract: A power generating element is provided. The power generating element includes an electrode pair and an intermediate layer. The electrode pair includes a first electrode and a second electrode. The intermediate layer is disposed between the first electrode and the second electrode. The intermediate layer is insulating and has a first side facing the first electrode and a second side facing the second electrode. The first electrode and the intermediate layer together operate as a contact/separation mechanism configured to perform a contact/separation operation, when an external force is applied to the power generating element to generate power. In the contact/separation operation, the contact/separation mechanism transitions between a contact or close state in which the first electrode and the first side are brought into contact with each other or close to each other, and a separation state in which the first electrode and the first side are separated from each other.
