Abstract: A memory system includes: a first nonvolatile memory; a second volatile memory; a controller; a power control circuit configured to perform control such that a first voltage is applied to the first memory, the second memory, and the controller based on first power supplied from an external power supply; and a power storage device configured to supply second power to the power control circuit while the first power from the external power supply is interrupted. While the first power supplied from outside is interrupted, the power control circuit applies a second voltage based on the second power supplied from the power storage device to the first memory, the second memory, and the controller. The power control circuit stops the application of the second voltage to the second memory after the data is read from the second memory and before the data is written into the first memory.

Abstract: Disclosed is the construction of a system capable of quickly and easily identifying patients having a risk for worsening inflammatory digestive tract disease by identifying a causal factor for the worsening of the inflammatory digestive tract disease. Specifically disclosed is a method for detecting oral bacteria that cause worsening of inflammatory digestive tract disease and/or a screening that targets high risk for worsening of inflammatory digestive tract disease and/or determining the risk for worsening of the inflammatory digestive tract disease by PA not being detected and/or CBP being detected, inclusive of the detection of PA, which is an oral bacteria protein antigen, and/or CBP, which is collagen binding protein, in samples. Also disclosed are a detection reagent and kit used for this method.

Abstract: Provided is a highly palatable and safe glucosyltransferase inhibitor or anti-dental caries agent. A glucosyltransferase inhibitor or anti-dental caries agent having an epigallocatechin gallate polymer or a salt thereof. Particularly, the above agent containing an epigallocatechin gallate polymer, which is a compound in which chroman rings are bonded at position 6 and/or 8 via a methylene group.

Abstract: Provided is a method that involves the detection of protein antigen (PA) and/or collagen-binding protein (CBP) of oral cavity bacteria in a sample, and in which oral cavity bacteria that exacerbate hemolysis are detected for and/or subjects at high-risk for hemolysis aggravation are screened anchor the level of risk of the hemolysis aggravation in a subject is assessed if a PA is not detected anchor a CBP is detected in the sample. Also provided are a detection reagent and kit for use in the method.

Abstract: An object of the present invention is to provide an atomic force microscope apparatus allowing tracking errors to be made as close to zero as possible to reduce images obtained through high-speed scanning from being degraded. To accomplish the object of the present invention, the present invention provides an atomic force microscope apparatus imaging a surface topography of a sample in a contact mode, the apparatus including a cantilever having a probe interacting with the sample surface via an atomic force and being subjected to a deflection by the atomic force, laser light provision means for allowing first laser light to enter the cantilever, light detection means, a controller estimating the surface topography of the sample surface, and data storage means for recording the estimated surface topography.

Abstract: Provided is a core wire contact detection device which detects contact between a strip blade and a core wire when a sheath of an electric wire is stripped by the strip blade. The core wire contact detection device includes a vibration detection unit capable of detecting a vibration in a frequency range including a vibration frequency generated due to the contact between the core wire and the strip blade, and a contact state determination processing unit which determines that the strip blade and the core wire are in contact with each other when an amplitude of the detected vibration exceeds a predetermined threshold value.

Abstract: A polynucleotide encoding a polypeptide which lowers the glucose side chain amount in a serotype-specific polysaccharide antigen of Streptococcus mutans; novel Streptococcus mutans strain having the above polynucleotide; an antibody specific to this Streptococcus mutans strain; and a method of detecting the above-described Streptococcus mutans strain occurring in a subject sample. According to this method, it is possible to examine the presence or absence of Streptococcus mutans of an untypable serotype in a subject sample to thereby specify a subject having a high risk of the onset of infective endocarditis.
