摘要： A hemispherical dielectric resonator is arranged on a metal substrate to make a flat surface of the hemispherical dielectric resonator contact with the metal substrate, and a dielectric wave-guiding channel is connected with a curved side surface of the hemispherical dielectric resonator. Therefore, a dielectric resonance antenna in which the hemispherical dielectric resonator and the dielectric wave-guiding channel are placed on the same metal substrate is obtained. A signal transmitting through the dielectric wave-guiding channel is fed in the hemispherical dielectric resonator, the hemispherical dielectric resonator is resonated, and an electromagnetic wave is radiated. Therefore, the dielectric resonance antenna functions as a wave radiation device.

摘要： An image processing portion for conducting the specified processing of an image to be reproduced by an image forming portion based on the processed image data is constructed as a single control portion. Consequently, the development of a variety of digital copying machines requires preparation of specially designated control boards according to levels of the products. This makes machines expensive and requires users to pay a considerable initial cost. An image processing device of the present invention is provided with an image information inputting means for inputting image information as a first level image, a main image-processing board for conducting the specified processing of the input image information of the first revel image, a sub image-processing board for conducting the specified processing of the image information processed by the main image processing board and outputting the information as a second level image, and a means for reproducing an image according to the image information processed by the main image-processing board or the sub image-processing board. These boards are independent from each other in the circuit configuration.

摘要： A device according to an aspect of the invention detects abnormality of spark plugs of an internal combustion engine. A value related to electric resistance across a gap between electrodes of each spark plug is measured. Next, it is determined whether or not the measured value, related to the electric resistance, assumes a value indicating that the electric resistance is below a predetermined value, when the engine is determined to be in a non-combustive state. The spark plug is determined to be abnormal when it is determined that the measured value, related to the electric resistance, assumes the value indicating that the electric resistance is below the predetermined value. A misfire-detecting system according to another aspect of the invention incorporates the above device.

摘要： A misfire-detecting system for an internal combustion engine in which a value of sparking voltage is detected, which is generated across a spare plug when high voltage is generated by an ignition device in response to generation of an ignition command signal. When a time period over which the detected value of sparking voltage exceeds a predetermined reference voltage value exceeds a predetermined time period value, the system determines that a misfire has occurred in the engine. A recharging command signal is generated for applying high voltage to the spark plug, after generation of the ignition command signal. As a result, a misfire can be accurately detected.

摘要： A copy-back type cache memory device using a delayed wait method capable of completing a data-write process in one process cycle. The device includes single word memory means for storing the single word of the selected data in a data memory means when an access for a data-write is made, the single word being located at the address in the data memory means corresponding to the processor address; and copy-back memory means for restoring the superseded data along with other data together with which the superseded data forms a block, so that the block can be reorganized in its original state before the data-write process takes place. The device may alternatively include an address latch means for delaying transmission of a processor address from the processor to the data memory means by a predetermined number of process cycles when access by the processor is for a data-write process; and a data latch means for delaying transmission of a processor data from the processor to the data memory means by the predetermined number of process cycles when access by the processor is for a data-write process.
