Abstract: According to one embodiment, an anomaly detection apparatus includes a processing circuit. The processing circuit is configured to: acquire measured values from sensors installed in a system, a first function, a first threshold, and a second function to output a second threshold; generate the predicted values based on the measured value and the first function; detect that a deviation between the measured values and the predicted values exceeds the first threshold; calculate the feature quantities based on the measured values; and determine whether a number of consecutive times is equal to or larger than the second threshold to detect an anomaly or a sign of the anomaly.

Abstract: A signal determination device includes an identification unit which identifies a reference signal that serves as a reference to identify an abnormal signal among a plurality of signals detected in the communication network, a time interval estimation unit which estimates a time interval of signals that are to be input in series to the communication network based on detection timing of the plurality of signals detected in the communication network, a timing estimation unit which estimates timing at which a plurality of signals is to be detected in the communication network after the reference signal, and a determination unit which determines whether each of the plurality of signals detected in the communication network after the reference signal is a normal signal based on the timing estimated by the timing estimation unit and detection timing of the plurality of signals detected in the communication network after the reference signal.

Abstract: A massage unit includes a treatment member; an arm that supports the treatment member; a drive shaft that supports the arm and causes the treatment member to approach and be separated with respect to a treatment target site; a movable portion that causes the treatment member to be operable in a direction of being separated from the treatment target site when the treatment member comes into contact with the treatment target site by a force equal to or greater than predetermined strength; and biasing means for biasing the treatment member in an approaching direction.

Abstract: A massage machine includes a backrest and a seat, and further includes a treatment unit configured to perform a treatment with respect to a subject; a measurement unit configured to measure beat rates of the subject or an amylase activity in saliva of the subject before and after a predetermined time; and an evaluation portion. The evaluation portion performs an evaluation of the treatment based on a first index indicating a parasympathetic nervous function activity of the subject and a second index indicating a sympathetic nervous function activity of the subject. The first index and the second index are obtained based on the beat rates or the amylase activity before and after the predetermined time.

Abstract: A tire manufacturing method includes the steps of, when a green tire is molded, moving a toroidally expandable toroidal molding drum through a distance between a plurality of working stations at a specified tact time, disposing a carcass band and both bead cores on the drum in any working station and locking the bead cores, increasing the diameter of the molding drum, toroidally extending the carcass band between both bead cores, and rolling up the side portion of the carcass band around the bead cores in the outer radial direction, assembling tire component members with the bead cores locked to the toroidal molding drum and molding the green tire, and reducing the diameter of the molding drum, unlocking the bead cores, and removing the green tire from the molding drum, whereby the tires of a plurality of sizes can be sequentially molded, a conventional tire structure must not be largely changed, and an energy and time can be prevented from being wastefully consumed.

Abstract: A toothbrush having a handle and a rubber-like brushing structure having a plurality of brushing projections and mounted on the forward part of the handle is further provided with a rigid frame member surrounding the side surface of the brushing structure and engaged with the latter in a projection-and-recess relation, the frame member being bonded to the handle for indirectly securing the brushing structure to the handle, and the "hardness" in operation of the toothbrush, i.e., the brushing projections, being adjusted by varying the height of the frame member measured perpendicularly to the lengthwise direction of the handle.

Abstract: A gum brush has an elongated handle with a stem end, to which is secured a brush head having a bullet shape and provided therearound in symmetrically distributed arrangement several fin-like projections some of which are parallel to the handle and others are perpendicular to the handle, these projections and the brush head being made of a rubberlike material such as cis-1,4-polyisoprene. In use, the brush head and projections are placed in an infant's mouth and moved at random or are chewed by the infant. As a result, the infant's teeth are cleaned, and, at the same time, its gums are firmed and strengthened.
