摘要:
A sensor device has a difference calculation unit that calculates the difference between a predetermined threshold and a current measured value measured by a sensor unit that measures a measurement subject, a change amount recording unit that records the maximum amount of change of the measured value with respect to elapsed time on the basis of a plurality of measured value history records obtained by measuring the measurement subject, and a minimum time calculation unit that calculates the minimum arrival time that is the minimum time for the measurement subject to arrive at the predetermined threshold from the current measured value on the basis of the calculated difference and the recorded maximum amount of change.

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.

A combustion control apparatus is configured for a direct-injection spark-ignition internal combustion engine. The combustion control apparatus selects an extremely retarded combustion mode while the internal combustion engine is in a predetermined operating state. In the extremely retarded combustion mode, the combustion control apparatus sets ignition timing to be after compression top dead center, and sets fuel injection timing to be before the ignition timing and after compression top dead center. The combustion control apparatus inhibits the extremely retarded combustion mode while an exhaust purifier of the internal combustion engine is in a predetermined cold state.

A guillotine cutter (1) of the invention is provided with a pressing block driving mechanism (6) positioning a pressing block (5) at a standby position which is spaced upwardly from a sheet bundle (10), a first operating position pressing the sheet bundle by a first pressing force, and a second operating position pressing the sheet bundle by a second pressing force which is larger than the first pressing force. The pressing block is carried by a rod (61) through a compression spring (62) at the standby position, the pressing block is supported on an upper surface of the sheet bundle at the first operating position, thereby applying the first pressing force to the sheet bundle on the basis of a resultant force of a gravitational force generated by its own weight and an biasing force generated by the compression spring, and the pressing block is pushed down by an expansion portion (61b) of the rod while the pressing block is kept being supported on the upper surface of the sheet bundle at the second operating position, thereby applying the second pressing force on the basis of a resultant force of the first pressing force and the push-down force generated by the rod.

An organic electroluminescent device includes a first member: a light-emitting element that is formed on the first member; a second member that has a second region bonded to the first region of the first member, and forms a sealing space for sealing the light-emitting element between the first member and the second member. Each of the first and second regions has a flat surface that is provided so as to connect an end portion located at the side of the sealing space to an end portion located at the side of an external space outside of the sealing space, and a wall surface that is provided near the flat surface, and the wall surface has a first surface that is provided so as to be parallel to a first direction, and a second surface that is provided so as to be parallel to a second direction different from the first direction.

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.
