摘要： In a resource request arbitration apparatus according to the present invention, a request masking unit masks a memory access request REQ that is issued by a resource requesting device at over a minimum frequency needed for the resource requesting device, and an arbitrating unit acknowledges one of the memory access requests RREQ that are not suspended by the request masking unit, based on a predetermined static order of priority. With this resource request arbitration apparatus, the arbitrating unit do not have to concern anything other than the predetermined priority order among the memory access requesting units, and an easy and plain arbitration system based on the static priority order ensures the minimum frequency for acknowledging the resource requests that each memory access requesting unit needs.

摘要： An optical information recording medium includes a plurality of recording layers, a reflectance of at least one of the plurality of the recording layers in a non-initialized state with respect to a light beam for initialization being smaller than a reflectance of the same in an initialized state with respect to the light beam for initialization. The recording layers are initialized by irradiating, among the plurality of recording layers, the recording layer positioned farther from a light beam irradiation side with the light beam prior to irradiating the recording layer positioned closer to the light beam irradiation side, so that the initialized recording layers have no initialization irregularities. In initialization, at a position at a same distance in a radial direction on the optical information recording medium, the recording layer positioned farther from a light beam irradiation side is irradiated with one light beam before the recording layer positioned closer to the light beam irradiation side is irradiated with another light beam so that the plurality of recording layers are initialized at the same time by a light beam projecting operation in which the light beams are focused at different positions. This ensures the initialization without irregularities within a short time.
摘要翻译：光学信息记录介质包括多个记录层，相对于初始化用光束，非初始化状态的多个记录层中的至少一个记录层的反射率小于初始化的光束的反射率相对于光束进行初始化的状态。通过在照射位于更靠近光束照射侧的记录层之前，在多个记录层之间照射位于离光束照射侧更远离光束的记录层，以便初始记录层没有初始化不规则。在初始化中，在光信息记录介质上沿径向相同距离的位置处，在距离光束照射侧更靠近的记录层之前，照射距光束照射侧更远的记录层用另一光束照射，使得多个记录层通过其中光束聚焦在不同位置的光束投影操作同时被初始化。这确保了在短时间内没有不规则的初始化。

摘要： An inexpensive bearing unit having a high rotational accuracy and a high reliability is provided for use in information and video-acoustic equipments. In the case of an oil-impregnated sintered bearing (1) in which an inner surface (2) sliding together with a shaft is formed on the bearing body (1) made of a porous sintered alloy, a plurality of concavities (4) are transferred to a tapered portion of the bearing inner surface (2) by forming a part or the whole of the inner surface (2) into a tapered shape or a tapered-like shape at the time of molding a green compact of the sintered alloy and press-fitting a pin (5) formed with protrusions (6) in the subsequent process and moreover, concavities (7) in which the shaft sliding surface is closed are formed by sizing the tapered portion straight at the time of sizing. Because the concavities (7) making a superior dynamic-pressure effect can be formed in a simple process, it is possible to provide an inexpensive bearing unit having a high rotational accuracy.

摘要： Methods and apparatuses for reducing noise in frequency to digital converters (FDCs). An FDC apparatus includes a first FDC, a second FDC and a combiner. The first and second FDCs are configured to independently sample an input signal according to a sample clock to generate first and second digital signals, each representing the instantaneous frequency of the input signal. The combiner is configured to form a resultant digital signal from the first and second digital signals. The first and second FDCs are designed and combined in the noise-canceling FDC apparatus so that the first and second signals they generate have correlated noise profiles in a frequency range of interest. When combined by the combiner to form the resultant digital signal, the resultant digital signal has a signal power to noise power ratio greater than the signal power to noise power ratios characterizing the first and second digital signals of the individual first and second FDCs.

摘要： An influence of a switching noise caused by a horizontal shift clock to an oscillation frequency of a voltage controlled oscillator should be eliminated, to prevent an image shift in a PAL skip period. For this purpose, an odd number line horizontal shift clock from an odd number line horizontal shift clock generator and an even number line horizontal shift clock from an even number line horizontal shift clock generator are switched by a horizontal shift clock switching circuit, to be input to a color LCD panel. The horizontal shift clock switching circuit selects and outputs either the odd number line horizontal shift clock or the even number line horizontal shift clock according to a line identifying signal, in a normal period. By contrast, in a PAL skip period a selecting state of the shift clock is inverted immediately upon start of a PAL skip period, from a selecting state right before the start of the skip period, and the selecting state is again inverted in half a cycle of a horizontal scanning period.
