Abstract: A data processing apparatus includes an arithmetic circuit that performs an acquiring step of acquiring swing data indicating relationship between a physical quantity concerning an amount of deformation of an object to be measured and time, a determining step of determining whether the swing data indicates the physical quantity concerning the amount of deformation of the object to be measured, which occurs when the object to be measured is swung, to determine whether the swing data is to be deleted, and a deleting step of deleting the swing data if it is determined that the swing data does not indicate the physical quantity concerning the amount of deformation of the object to be measured, which occurs when the object to be measured is swung.

Abstract: A sensor unit includes: a sensor that is attached to a measurement target object becoming deformed in response to a swing taken with the measurement target object and that generates an output signal indicating a relationship between a physical quantity related to an amount of deformation of the measurement target object and a time; a feature value generation circuit that generates a feature value, the feature value being a parameter indicating a feature of the swing, on the basis of the output signal obtained by the sensor; and a communication unit that is attached to the measurement target object and that transmits the feature value to an external device by wireless communication or wired communication.

Abstract: A processing device includes an operation circuit that determines based on a first signal a swing start time, the first signal being acquired from a sensor that is attached to a striking member for striking a to-be-struck object by being swung and that detects deformation of the striking member when the striking member is swung. An absolute value of a difference between a reference value and a value of the first signal is defined as a first difference value. The operation circuit executes a first determination step in which an impact time is determined based on one or more times at which the first difference value becomes greater than or equal to a first determination value.

Abstract: Provided is a sensor unit including a first sensor portion that detects deformation of a measuring target object and a second sensor portion that detects deformation of the measuring target object, in which in a state in which the first sensor portion and the second sensor portion are attached to the measuring target object, the first sensor portion and the second sensor portion are fixed to the measuring target object such that the measuring target object is disposed between the first sensor portion and the second sensor portion in a first direction, and a physical property value of the first sensor portion and a physical property value of the second sensor portion are changed according to first deformation of the measuring target object.

Abstract: To provide a floor coating composition and floor coating composition additive. It is possible to improve the leveling performance, mopping performance, and other properties of a floor coating composition over those obtained with a conventional tributoxyethyl phosphate leveling agent by adding to a floor coating composition 1) a (C7-C10) aliphatic monocarboxylic acid monoester of a diol, or 2) a (C7-C10) aliphatic monocarboxylic acid monoester or diester of a triol.

Abstract: A multiple projection television system is comprised of a plurality of projection units stacked in matrix to form a large television screen. Each of the projection units has a cabinet, a projector provided in the cabinet, and a screen secured to a front portion of the cabinet. A mounting frame is provided in the cabinet for slidably mounting the projector in forward and rearward directions. A back of the cabinet is opened so as to allow removing of the projector from the cabinet. The screen is detachably secured to the cabinet so as to allow removing of the projector from the cabinet.

Abstract: A projection television set includes a body composed of at least two divided upper and lower units, a screen assembly having an integrally formed screen corresponding to the body, and a plurality of bolt and nut assemblies for coupling the divided units together. Each of the upper and lower units has a projector for emitting light rays for forming an image on a screen and a reflector for reflecting the light rays from the projector onto the screen. The projector of the lower unit is arranged below the reflector of the lower unit, and the projector of the upper unit is arranged in an intermediate position between the reflector of the upper unit and the reflector of the lower unit so that setting angles of the two reflectors are different from each other. A screen assembly is mounted on a front face of the body.

Abstract: A projection television set in which a seamless image may be obtained on a screen. A screen plate of a screen assembly is held under a suspended state by a frame in a state wherein the left and right parts are centered in the frame. A cruciform light-shielding frame is mounted on the frame. A light-shielding plate is swingably mounted on a horizontal light-shielding frame of the frame. The position of the light shielding plate is adjusted in response to the vertical movement of a horizontal joint. Also, the horizontal joint line adjusting mechanism is provided independently of a centering mechanism for a vertical joint line.
