摘要:
In a semiconductor memory device of a divided bit line system, read signals from memory cell blocks are sense-amplified together by a single differential bit line sense amplifier. The bit line sense amplifier includes a plurality of first transistors, the base electrodes of which are connected to local bit lines of the memory cell blocks, the emitter electrodes of which are commonly connected to corresponding main bit lines, and the collector electrodes of which are connected to a first power supply node, a second transistor, which forms a differential pair with each of the first transistors, the base electrode of which is applied with a reference bias potential, and the emitter electrode of which is connected to the main bit lines, a current source connected between the emitter electrode of the second transistor, and a second power supply node, and a load circuit connected between the collector electrode of the second transistor and the first power supply node. The main bit lines with a heavy load can be driven by the emitters having a large driving force, and the outputs from the memory cell blocks can be sensed without going through selectors, thus attaining high-speed read access.

A semiconductor memory circuit device having memory cells constructed on a BiCMOS gate array includes amplifying means constituted by a bipolar transistor connected to the output stage of each of memory cells arranged in a matrix form on a semiconductor substrate and formed in a gate array memory cell configuration by use of the Master slice approach. The amplifying means amplifies the potential level of readout data of the memory cell and output the same to an output line, thus enhancing the driving ability of the output line and reducing the whole readout time for reading out data from the memory circuit.

The present invention is to provide meiosis-specific novel kinetochore protein Sgo1 (shugoshin) derived from fission yeast Schizosaccharomyces pombe, and a homologue or paralogue thereof having a regulatory activity of chromosome segregation; and DNAs encoding them; as a factor ensuring the retention of unidirection and cohesion in sister centromere at meiosis I in cooperation with cohesin. To elucidate the proteins protecting Rec8 during anaphase, the present inventor screened in fission yeast genes for a gene that inhibits mitotic growth and prevents sister chromatid from the separation at anaphase, when co-expressed with Rec8. In this approach, meiosis-specific protein Sgo1 that protects (Shugo) centromeric Rec8 from the degradation at anaphase I was indentified. Further, a budding yeast Sgo1 homologue and a fission yeast mitotic paralogue Sgo2 were identified.

An image processing apparatus uses a bird's eye image for supporting a backing operation of a vehicle for parking. The bird's eye image is processed to display an area view that at least includes a parking lot captured in the image. Then, the area view is displayed in a display space in a display unit of the image processing apparatus for representing a parking area and related information. In this manner, the area view excludes unnecessary part from the bird's eye image for effectively providing a visual support for the backing operation by a driver of the vehicle.

A rate conversion unit determines a frame thinning-out rate to thin out frames on the basis of a recording rate at the time of photographing and a display rate for display on a display apparatus so that a temporal updating interval of a video image between continuous fields becomes constant. After that, a frame is repeatedly inserted so that a frame rate becomes equal to the display rate.
