An electrophotographic photoreceptor containing an intermediate layer provide between a support and a photosensitive layer is disclosed. The intermediate layer contains at least one of an organic metal compound and a silane coupling agent or a product therefrom and its membranaceous index is 0.5 or more and 10 or less. The electrophotographic photoreceptor has low residual potential wherein no image defects such as spotting are caused over a long period of use.

In a semiconductor memory device selectively implementing one of a 4K refresh cycle and a 8K refresh cycle, the positions of externally applied address signal bits are switched internally by address switching circuits such that memory cells at the same positions are selected regardless of whether the 4K refresh cycle or the 8K refresh cycle is specified according to a refresh cycle mode specify signal. As a result, by testing the device in one refresh cycle mode, the device can be checked in both refresh cycle operations, reducing the test time and making the test easier.

In a memory plane of a semiconductor memory device, transmission gate circuits for transferring data between local I/O line pair and global I/O line pair, and equalizing circuits for equalizing the local I/O line pair are arranged alternately on both sides of a shunt region. All the global I/O line pairs extend entirely over the memory plane. One and the other global I/O lines are arranged in symmetry, with a line for transmitting bit line precharge voltage, cell plate voltage or local input/output line equalizing signal being the center.

A sheet sorting apparatus of a moving bin type for sorting sheets received successively from a sheet delivery station into collated sets, which apparatus comprises. This sheet sorting apparatus includes a plurality of trays stacked one above the other in a vertical direction, and vertically movably supported by a frame structure, first and second camming members extending in a direction parallel to a direction of movement of the trays and having helically continuing threads each having an upwardly oriented camming face engageable with any one of the trays, a sheet delivery mechanism for successively discharching the sheets towards the delivery station, and a drive motor drivingly coupled with the first and second camming members for driving the camming members about respective longitudinal axes of the camming members to move the trays up and down therealong. The helicatly continuing threads is divided into a low pitch region in which each neighboring threads are spaced a small pitch and a high pitch region in which the neighboring threads are spaced an increased pitch. The first and second camming members are so supported with their high pitch regions confronting the sheet delivery station, one of the trays supported on the thread in the high pitch region being permitted.

A transaction management system is capable of simply and accurately gathering information about the use of medical products with minimized human errors and automatically executing issuance of invoices of suppliers and restocking of used products on the basis of the results of use of products deposited at medical centers. The system comprises a computer system having an antenna electrically connected to a reader and a medical product encapsulated in a sterilized environment in a package. The package is provided with an IC tag arranged such that signal transmission and/or reception is disabled while the package remains unopened so that the medical product is in the sterilized condition. The IC tag becomes wirelessly communicable with the antenna when the package is opened to remove the medical product. The computer system reads the product information about the medical product from the IC tag now wirelessly communicable with the antenna and, on the basis of the obtained product information, places an order to a supplier for the replenishment of the used medical product through a dedicated line or an external network.
摘要:
In a burn-in test, a sense amplifier circuit is separated from each bit line by a bit line separation switch. In this state, a bit line switch circuit connects one of complementary bit lines to a first voltage node, and connects the other complementary bit line to a second voltage node in blocks on both sides. A first bit line voltage supplied by the first voltage node and a second bit line voltage supplied by the second voltage node can be set independently of each other at least in the burn-in test.
