An estimation system includes: a first sensor that can be disposed between a wheel and a tire mounted on the wheel and outputs a first sensor signal in accordance with a pressing force applied by the wheel and the tire; and a processor that estimates a state of a rotating body including the wheel and the tire based on the first sensor signal. The processor generates a first section signal by dividing the first sensor signal by a specific section and estimates the state of the rotating body based on the first section signal.

Estimation system, estimation method, and recording medium

An evaluation device according to one aspect of the present invention includes an extractor configured to extract data related to a brand preset by a company or an organization from data collected from an information medium, and a calculator configured to calculate a first index value indicating a frequency of appearance of a first term indicating content expected by the company or organization in the data extracted by the extractor and a second index value indicating a frequency of appearance of a second term indicating a response of a customer in the extracted data.

Evaluation device, evaluation method, and evaluation program

An object of the present invention is to obtain an easy-to-work solar battery module having high joining strength as well as suppressing an increase in residual thermal stress without increasing the thickness of an interconnector. The solar battery module of the present invention includes a solar battery cell including a semiconductor substrate having pn junction, and a first electrode and a second electrode that are formed on a p-type region and an n-type region of the semiconductor substrate and an interconnector to connect the solar battery cell and an adjacent solar battery cell. The interconnector is a bundle of a plurality of round thin wires and includes abutment regions abutting on the first electrode and the second electrode of the adjacent solar battery cell.

Solar battery module and method for manufacturing solar battery module

A muffler of a motorcycle having an outside diameter greater than the outside diameter dof a rectilinear portion of a branch pipe is disposed at a transverse portion of an exhaust pipe. Since the muffler is formed to be roughly elliptic in sectional shape, the outside diameter of the muffler is represented by a major diameter das the length in the direction of a major axis and a major diameter das the length in the direction of a minor axis. When the muffler is disposed between a swing arm and a seat to be along the transverse portion of the exhaust pipe, the muffler can be disposed on the more vehicle front side while securing the capacity thereof. Therefore, protrusion of the muffler toward the rear of the vehicle is suppressed, and the external appearance of a vehicle rear portion is enhanced.

Exhaust system for motorcycle

An exhaust pipe connected to an exhaust port of an engine and an expansion chamber is disposed in the vicinity of the engine. A main tube is provided that extends rearwardly from a head pipe disposed at the front side of a main body. An engine having a cylinder extending upwardly from a crankcase is disposed under the main tube with an exhaust port open at the front side of the cylinder. A first exhaust pipe is provided that is connected to the exhaust port. A down tube is disposed on the center line in the left-right direction of the main body. The exhaust port disposed behind the down tube is deviatingly open at one side from the center line. The first exhaust pipe extends forward from one side of the down tube, and to the other side of the down tube, subsequently turns, and extends again to one side.

Exhaust structure of motorcycle

Provided are a ferroelectric material having good ferroelectricity and good insulation property, and a ferroelectric device using the ferroelectric material. In the present invention, the ferroelectric material includes a metal oxide having a perovskite-type crystal structure, in which: the metal oxide contains bismuth ferrite whose iron is substituted by manganese, and at least one of a copper oxide and a nickel oxide; the bismuth ferrite is substituted by manganese at a substitution ratio of 0.5 at. % or more to 20 at. % or less with respect to a total amount of iron and manganese; and at least one of the copper oxide and the nickel oxide is added in an amount of 0.5 mol % or more to 20 mol % or less with respect to the bismuth ferrite whose iron is substituted by manganese.
