Abstract: A solid-state imager 20 outputs image signals corresponding to picture elements received from light-receptive areas thereof. A sample-and-hold circuit 24 performs a sample-and-hold operation for the image signals at prescribed times. A driving circuit 22 generates driving pulses and sample-and-hold pulses. A horizontal charge-transfer circuit of each light-receptive area is driven with the driving pulses, and the sample-and-hold circuit 24 is driven with the sample-and-hold pulses in synchronization with the driving pulses. The driving circuit 22 intermittently drives the horizontal charge-transfer circuit and the sample-and-hold circuit after the output of at least one of the first and last image signals. Consequently, noise that would be produced in picture elements located at the junctures between adjoining light-receptive areas can be reduced, and loss of image quality that would be caused by the effects of operations in subsequent processes performed in various circuits can be reduced.

Abstract: The present invention provides a data recording device which starts recording data a to a memory A when a command is given to start recording data. When the remaining capacity of the memory A is not greater than a given capacity value x, data recording to the memory A is concurrent with data recording to a memory B. When the capacity of the memory A is full, recording data x to the memory A is ceased. Thereafter, when a command is given to cease an operation for recording data to the memory B, an inquiry is made as to whether space capacity of the memory B is greater than an amount of data a of the memory A. Only when the inquiry is answered in the affirmative, the data a recorded on the memory A is copied to the memory B.

Abstract: A journal of a crankshaft is rotatably supported by a journal-supporting portion of a cylinder block and a bearing cap. An arcuate oil guide groove is defined in a side face of the bearing cap, and coils which are portions of a stator of a generator or motor are fitted into an oil guide groove. Oil flowing down from an oil return passage provided in the cylinder block and oil flowing down from a blow-by gas passage, flow downwards from an upper end of the oil guide groove and return through an opening to an oil pan. In this process, the oil is brought into contact with the coils to cool the stator. Therefore, even if the stator is located above the oil stored in the oil pan, the stator having a raised temperature can be cooled efficiently, to thereby prevent degradation of the performance of the generator or motor.

Abstract: A wavelength selection filter, a wavelenth selection laser, and a tunable laser for suppressing adverse effects of non-selected light when selected light is obtained by the wavelength selection filter. A linear polarizer is arranged on a side of the wavelength selection filter from which incoming light enters, and a first faraday element and a second faraday element arranged at respective locations between the linear polarizer and the wavelength selection filter, and between the wavelength selection filter and a reflection mirror for reflecting light having passed through the wavelength selection filter. After incoming light passes through a linear polarizer, selected light passes through the wavelength selection filter and is reflected by the reflection mirror, while non-selected light is reflected by the wavelength selection filter. The selected light and the non-selected light differ in the number of times they pass through faraday elements before they return to the linear polarizer.
