An image generating system is structured to transfer the N-dot multivalued image data from an image generating device to write them on the N numbers of FIFO memories in synchronism with a specific transfer clocking, and to read them out to the engine by the clock having 1/N transfer frequency. This clock synchronizes with the horizontally synchronous signals. Then, the image data are selected by means of a selector one after another for output. The multivalued image data thus output are converted into the binary image data to be transferred to the engine in synchronism with the transfer frequency. In this way, the system can be formed simpler with ease as desired.

A sequence controller of the digital logical circuit type, comprising a sequence program part and a processing circuit, wherein the desired sequence instruction is read from the sequence program part, and the sequence is processed and controlled by the processing circuit. A certain definite level is set at a branch point in an equivalent sequential circuit according to the path along which a signal of the sequential circuit is transmitted. This level and the on-off state of the branch point are stored in a memory. The given data are processed and controlled through the sequence program part and the memory.

Radiated noise caused by switching noise of power semiconductor elements in an electrical converter is reduced. The electrical converter is characterized in comprising: a case; a power module mounted on the case and comprising a plurality of power semiconductor elements; a metal plate mounted to the power module and fixed to the case; a control circuit board arranged on the metal plate, for controlling the power semiconductor elements; and a direct-current input terminal electrically connected to a battery. The electrical converter is also characterized in being provided at the bottom with a transmission or motor, and at the top with a connector for connecting the battery and the direct-current input terminal. The electrical converter is further characterized in that the metal plate is curved, and a portion of the curved metal plate is arranged in the space between the control circuit board and the direct-current input terminal.

A system for reducing electromagnetic noise generated by common mode currents in electrical connections of a power inverter and battery in an electric or hybrid electric vehicle. A pair of spaced apart electrical conductors extends along the vehicle chassis and electrically connects the power inverter to the battery. An electrically conductive metal plate is positioned in between the spaced apart electrical conductors. This metal plate is electrically connected to the chassis adjacent at least both of the power inverter and the battery/motor. Besides this, more connecting points are required to keep the distance between two points less than half wavelength of the maximum frequency of EMI requirements, and most preferably this metal plate is electrically connected to the chassis all the way with infinite connecting points. The metal plate is positioned so that the metal plate is closer to the electrical conductors than the space in between the electrical conductors and the vehicle chassis.

An image reading apparatus includes a light-emitting device having a peak wavelength that varies depending on a value of a drive current, and illuminates a document with illumination light from the light-emitting device. A light receiving unit receives a light reflected from the document when the illumination light is emitted from the light-emitting device, and converts the received reflected light into image data at a predetermined sensitivity depending on the wavelengths of the received light. A current drive circuit supplies the drive current to turn on the light-emitting device. A wavelength distribution control unit produces two or more durations each having a different value of the drive current by controlling the current drive circuit during each main scanning to the document to produce two or more durations each having a different peak wavelength in each main scanning.
