Disclosed are two lectin species isolated from the hemolymph of Japanese horseshoe crabs and Southern horseshoe crabs which bind to N-acetylneuraminic acid and N-glycolylneuraminic acid, but not to N-acetylglucosamine, glucoronic acid, or N-acetylgalactosamine.

A resin-seal type semiconductor device includes a main substrate divided into first and second surfaces on which first and second insulating substrates are respectively provided. Circuit wiring patterns and first end portions of outer leads are provided on the first and second insulating substrates. Semiconductor elements are soldered onto the wiring patterns and coated with a surface protection material. The main substrate is then folded over so that the first and second surfaces oppose one another and the device acquires a U-shaped cross-section. A space formed between the first and second surfaces inside the U-shape is sealed with a resin such that second end portions of the outer leads are exposed from the resin.

A method of controlling the concentration of P of cleaning solution waste water starts by providing a waste water buffer tank capable of either sending the waste water to a waste water treatment plant or storing the waste water after the waste water is accepted. The concentration of P in the cleaning solution is set within a target concentration range, and matter to be treated is treated. The concentration of P in the waste water is measured in the waste water buffer tank. When the measured value of the concentration of P is less than a selected upper limit, the waste water is sent from the waste water buffer tank to the waste water treatment plant. When the measured value of the concentration of P is higher than the selected upper limit, sending the waste water to the waste water treatment plant is stopped, and the waste water is stored in the waste water buffer tank. The concentration of P is reduced to a value within the target concentration range, and the matter to be treated is treated.

A halftoning device that converts an input pixel signal of 8 bits per pixel into an output pixel signal of r bits per pixel(r 8); a threshold value array storage that stores a threshold value array having a threshold value of 8 bits; and a threshold value expansion unit that expands the threshold value of 8 bits to expanded threshold value of n bits per pixel. A range of the expanded pixel signal output from the gradation correction unit is matched with a range of the expanded threshold value. The output pixel signal is set according to a comparison of the expanded pixel signal with the expanded threshold value corresponding to the threshold value that is selected for each input pixel signal.

An image processing apparatus for compressing and decompressing image data is disclosed that is capable of image processing with a small memory area. The image processing apparatus includes a compression unit to compress the image data to a predetermined compression format; an omission secondary compression unit to omit a portion of the compressed image data given by the compression unit, divide the compressed image data into blocks having predetermined block sizes, and perform secondary compression to generate omission secondary compression image data; a data recovery unit to recover the omission secondary compression image data into the compressed image data; an image rotation unit to rotate the compressed image data decompressed by the data decompression unit according to the block sizes; a block storage unit to store the rotated compressed image data in units of the block sizes; and a data decompression unit to decompress the compressed image data stored in the block storage unit according to predetermined conditions.
