  • Publication number: 20210143193
    Abstract: The present disclosure relates to a solid-state imaging device and an electronic apparatus which allow reduction of optical crosstalk. In an example of FIG. 5B, a charge storage unit is formed by a method in which a hole is bored in a substrate, a diffusion layer is formed in a surface of the hole, and an insulating film and an upper electrode are formed so as to fill the hole. In an example of FIG. 5C, a charge storage unit is formed by a method in which a hole is bored in a substrate, a diffusion layer is formed in a half (one side) of a surface of the hole, and an insulating film and an upper electrode are formed so as to fill the hole. By placing the charge storage unit (capacitance element) formed in the substrate in the foregoing manner between PDs which are first photoelectric conversion units, it is possible to allow the capacitance element to function as a shield pair against crosstalk between the PDs in a unit pixel.

  • Patent number: 10934962
    Abstract: An abnormality diagnosis device of an in-cylinder pressure sensor is provided. The device carries out a performance determination in which a performance quality of the sensor is determined based on an electric signal inputted from the sensor. The device carries out a first determination in which the performance determination is performed at a given timing, a performance recovery in which a given deposit removal control is executed in which a deposit accumulating inside the combustion chamber is removed when the performance quality of the in-cylinder pressure sensor is determined to fall below a given reference value, and a second determination in which the performance determination is carried out again after the performance recovery. In the second determination, the in-cylinder pressure sensor is diagnosed as abnormal when the performance quality of the sensor is determined to fall below the given reference value.

  • Patent number: 10876488
    Abstract: A failure diagnosis device for an in-cylinder pressure sensor is provided, which includes an in-cylinder pressure sensor, and an engine controller comprised of circuitry configured to execute a diagnosis module into which a signal of the sensor is inputted, to diagnose a failure of the sensor based on the signal. The diagnosis module includes a reading module configured to read the signal of the sensor within a specific crank angle range, a reference phase determining module configured to determine a reference phase that is a phase of a pressure change accompanying a volume change of the combustion chamber, and a failure determining module configured to determine that the sensor has failed, when the failure determining module determines a phase of the read signal of the sensor is delayed by an amount exceeding a predefined threshold from the determined reference phase.

  • Patent number: 10815917
    Abstract: A failure diagnosis system for an in-cylinder pressure sensor is provided, which includes an in-cylinder pressure sensor, a fuel injection valve, an engine controller including an engine control module and a diagnosis module. The engine control module controls the fuel injection valve to stop the supply of fuel to the engine, when a fuel cut condition is satisfied while the automobile travels. The diagnosis module includes a limiting module configured to limit an execution of the failure diagnosis of the in-cylinder pressure sensor until the diagnosis module determines that a given period has lapsed after the stop of fuel supply to the engine. The diagnosis module reads a signal of the in-cylinder pressure sensor when the given period has lapsed after the stop of the fuel supply to the engine, and diagnoses the failure of the in-cylinder pressure sensor based on the read signal of the in-cylinder pressure sensor.
