Abstract: A reading apparatus, having a document placement table, a cover, a reader, and a controller, is provided. The cover has, on a facing surface thereof that faces the reader, a reference section having a first edge extending in a sub-scanning direction and a second edge extending in a main scanning direction, and a colored part on peripheries of the reference section. The colored part is colored along the first edge and along the second edge. The controller is configured to operate the reader to read the colored part and the peripheries of the colored part, detect a first position being a position of the first edge in the main scanning direction and a second position being a position of the second edge in the sub-scanning direction in an outcome of reading, and determine a reading range based on the first position and the second position.

Abstract: A semiconductor device storing data as a multilevel potential is provided. The semiconductor device includes a memory cell, first and second reference cells, first and second sense amplifiers, and first to third circuits. The first circuit has a function of outputting, to a first wiring and a third wiring, a first potential corresponding to a first signal output from the memory cell. The second circuit has a function of outputting, to a second wiring, a first reference potential corresponding to a second signal output from the first reference cell. The third circuit has a function of outputting, to the fourth wiring, a second reference potential corresponding to a third signal output from the second reference cell when a second switch is in an off state. The first sense amplifier refers to the first potential and the first reference potential and changes potentials of the first wiring and the second wiring.

Abstract: This invention aims at developing a sanitary body cavity sealing device which prevents leakage of substances in the rectum of a corpse due to anal muscle relax after die, simplifies the postmortem treatment work for persons working on it or nurses and prevents infection to the persons, nurses or those around due to leakage of body internal substances. The body cavity sealing member (10) is made of porous fiber elements that absorb water on contact with body fluids in a body cavity to expand up to approximately 2.5 or more times its diameter, its end part (15) is cut into a tapered shape and the cut surface (15) is processed, for example, by heat treatment, to form a smooth surface. By inserting the body cavity sealing member (10) with the end part first into the anus, it can be inserted into the rectum without being interfered with by the inner walls of the anus and rectum.

Abstract: A closing member (16) is disengageably fitted to one end of a cylindrical-shaped guide member (4) to close an opening (4a) of the guide member (4). A water-absorbing agent (3) made of water-absorbing resin powder is accommodated in the guide member (4) toward the one end. A column-shaped plug member (2) made of water-swellable fibers is accommodated in the guide member (4) at a location closer to the other end than the water-absorbing agent (3). A push rod (5) is inserted into the guide member (4) through an opening (4b) thereof located at the other end. With the opening (4a) at the one end of the guide member (4) inserted in an anus, the push rod (5) is operated to push the water-absorbing agent (3) and the plug member (2) through the opening (4a) at the one end of the guide member (4) into a rectum. The plug member (2) absorbs water in internal contents and expands to plug the rectum, while the water-absorbing agent (3) also absorbs water in the internal contents.

An expandable sealing member (2) is made of porous fiber elements that absorb water on contact with body fluids in a body cavity to expand up to approximately 2.5 or more times its diameter. The expandable sealing member (2) is inserted, in the form loaded in a cylindrical member (3), into a body cavity such as an anus, pushed out of the cylindrical member (3) by a rod member (10) to reside in the rectum, rapidly absorbs water to swell, comes into tight contact with the inner wall of the rectum, further expands the rectum and seals the passage of the rectum.
