摘要： A cover member of an ultrasonic sensor has a first engagement portion and a second engagement portion, which are respectively engaged with a third engagement portion and a fourth engagement portion of a sensor body. The engagement portions are arranged in such a manner that a force applied to the cover member due to an engagement between the first engagement portion and the third engagement portion and a force applied to the cover member due to an engagement between the second engagement portion and the fourth engagement portion respectively have opposite directions to be substantially countervailed when the sensor body is attached to the cover member. Thus, the cover member can be restricted from slanting when the sensor body is fixed to the cover member.

摘要： An ultrasonic sensor has a sensor body and a bezel having a metal spring attached on a side wall thereof for installation on a vehicle component. A free end of the metal spring is positioned to protrude from a through hole of the side wall, is pressed by a portion of the sensor body that is inserted in a hollow space of the bezel, and is pushed back by an opening face of the sensor body. In this manner, the bezel is firmly attached on the component and the sensor body is firmly attached on the bezel.

摘要： A structure is used to prevent an ultrasonic sensor from being damaged by a spring member provided for a bezel. A metal spring is fixed in a groove in a bezel. By setting depth of the groove to be larger than thickness of the metal spring, the metal spring is positioned on the inside further than an open end of the bezel. With the configuration, the metal spring is prevented from coming into direct contact with an ultrasonic transducer. Thus, a vibration face of the ultrasonic transducer is prevented from being damaged.

摘要： A semiconductor device comprises three semiconductor layers. The semiconductor layers are arranged to form a 2DHG and a 2DEG separated by a polarization layer. The device comprises a plurality of electrodes: first and second electrodes electrically connected to the 2DHG so that current can flow between them via the 2DHG and a third electrode electrically connected to the 2DEG so that when a positive voltage is applied to the third electrode, with respect to at least one of the other electrodes, the 2DEG and the 2DHG will be at least partially depleted.
