    摘要: An imaging device reads an output level of a pixel circuit constituting a pixel array by supplying current to the pixel circuit. It reads a signal level and reset level from the pixel circuit by supplying it with the current from a current source circuit, and stores them into a line memory. A pixel level of the pixel circuit is obtained by a differential amplifier that outputs the difference between the signal level and reset level of the same pixel circuit. The gate potential of a current copier transistor that supplies the read current is set at a value that enables the read current to take a constant value from column to column of the pixel array. The image device can suppress variations in the current copier circuit provided for each array column of the pixel circuits, thereby reducing string-like noise in the image picked up.

    摘要: A vertical type power MOSFET made of silicon carbide includes a surface channel layer doped with nitrogen as dopant with a concentration equal to or less than 1×1015 cm−3. Accordingly, when a gate oxide film is formed on the surface channel layer, an amount of silicon nitride produced in the gate oxide film and at the interface between the gate oxide film and the surface channel layer becomes extremely small. As a result, carrier traps are prevented from being produced by silicon nitride, resulting in stable FET characteristics and high reliability to the gate oxide film.

    摘要: In an image sensing apparatus, an array of two-dimensional matrix of photosensitive devices is used to detect an image. Each photosensitive device comprises a photosensor accumulating carriers when exposed to a light, control terminals, and an output terminal. A signal generator supplies a vector or a one-dimensional data to the control terminals in the array to output pixel data of the two-dimensional matrix, and the pixel signal is output through the output terminal. The control terminals of the photosensors arranged along each line are connected commonly, while the output terminals thereof arranged along each column are connected commonly. A controller supplies control signals to the control terminals. Then, pixel signal for columns designated by a control signal are output through an output circuit connected to the control terminals. Then, a partial region in the array including a region exposed by the light is determined according to the pixel signals, and data on the partial region is sent to the controller. Then, the controller supplies control signals in correspondence to the partial region. Then, correlation operation of the control signals with the amount of carriers in the photosensors are carried out while reading the pixel signals, and the pixel signals in the partial region is output.

    摘要: A control apparatus for a dazzle-free reflection mirror of a vehicle is disclosed. The control apparatus is provided with a rear light sensor and a circuit for driving the reflection mirror into a dazzle-free condition in accordance with an intensity of a rear light detected by said rear light sensor when a light switch is turned on. The control apparatus is further provided with a winker manipulation detecting switch, a reverse position detecting switch and a steering wheel detecting switch for detecting a change in the moving direction of the vehicle. When one of them detects the change in the vehicle moving direction, the dazzle-free operation of the reflection mirror is disabled even if intensive light is incident to the reflection mirror from the rear of the vehicle.
