Abstract: An AD conversion device includes an AD converter that outputs an analog signal as sampling data for every sampling point based on a sampling frequency, a controller, and a storage circuit, the controller includes a buffer memory which temporarily stores the sampling data from the AD converter in time series and from which the sampling data is read out in time series, and a decimation controller, the decimation controller outputs a write-enable signal indicating write-enabled for the selected sampling data in the decimation region and the sampling data in the high-speed sampling region, and outputs decimation bit information indicating whether the sampling data is the sampling data of the decimation region or the sampling data of the high-speed sampling region, and the storage circuit stores the sampling data stored in the buffer memory in association with the decimation bit information, in response to the write-enable signal.

Abstract: A gas cracking apparatus adapted to simultaneously efficiently discharge gas heavier than air and gas lighter than air resulting from assimilations of malodorous gas and greenhouse gas. The main frame of the gas cracking apparatus includes a closed metallic circular tube or angular tube. This tube is provided at its superior portion with a superior vent and provided at its inferior portion with an inferior vent, and the tube is further provided with a gas inlet disposed between the superior vent and the inferior vent.

Abstract: An antibody biding specifically to rat's acrosome reacted sperm is produced and hybridomas (FARS-91 and FARS-92 strains) capable of stably proliferating are obtained by fusing mouse spleen cells having a high antibody titer against rat's acrosome reacted sperm with mouse-origin myeloma cells and screening fused cells reacting strongly with rat's acrosome reacted sperm. From these hybridomas, monoclonal antibodies selectively binding to rat's acrosome reacted sperm can be obtained. Thus, a diagnostic method for evaluating fertility of rat's spermatozoa is presented.

Abstract: The present invention can provide the nonaqueous electrolytic secondary battery excellent in cycle life characteristics and characteristics in discharge at a high rate as well as in safety in overcharge without reducing the discharge capacity by using the positive active material, which is obtained from starting materials containing Na and S by a simple production step such as water-washing treatment after synthesis and which contains less than 0.1% by weight of the sulfate group (SO42−), less than 0.024% by weight of Na and/or less than 0.13% by weight of lithium sodium sulfate (LiNaSO4).
