A pressure sensor includes a cylindrical case defining an inner space in communication with an outer space; a pressure detector provided in the inner space and configured to detect a gauge pressure of a target fluid; an atmospheric pressure detector configured to detect an atmospheric pressure; and an electronic component configured to calculate an absolute pressure of the target fluid on a basis of the gauge pressure and the atmospheric pressure. The absolute pressure is obtained without requiring airtightness of the case between the inner space and the outer space, and thus, there is no requirement for a seal member to be included between the inner space and the outer space.

Pressure sensor with increased absolute pressure detection

A vehicle abnormality detecting apparatusincludes wheel load sensorsthat are attached to right and left rails R constituting a track to measure wheel loads of wheelsprovided in a vehicle; and a calculation unitthat is connected to the wheel load sensors. An index represented by wheel loads of a pair or more of right and left wheelsprovided in at least one of bogiesand defined according to a type of vehicle abnormality as an index for detecting the vehicle abnormality is previously stored in the calculation unit. The calculation unitcalculates a value of the stored index from the wheel loads measured by the wheel load sensorsand transmitted from the wheel load sensors, and detects the abnormality of a running vehicle based on the calculated value of the index.

Method and apparatus for detecting abnormality of vehicle

Provided is an oral composition that can sufficiently remove protein staining present on a tooth surface, can effectively prevent adhesion of protein staining on a tooth surface and can provide a good actual feeling of the cleaning effect in the oral cavity. The oral composition comprises the following components (A) and (B): (A) an N-acylamino acid or a salt thereof in an amount of 0.005 mass % or more and 0.3 mass % or less; and (B) pyrophosphoric acid or a salt thereof in an amount of 0.005 mass % or more and 0.5 mass % or less, in which a mass ratio ((B)/(A)) of the component (B) to the component (A) is 0.05 or more and 40 or less and a total content of the component (A) and the component (B) is 0.01 mass % or more and 0.6 mass % or less.

Oral composition

A forced-insertion welded structure is provided which is formed by welding members making up a metal component and which is easy to manufacture and has low cost, a good finish precision and a high bonding strength. The forced-insertion welded structure comprises: a first memberwith a holewhich has the same geometry as a cross section of a forcibly inserted portion of a second member; and the second memberhaving a constant cross section over its length which is similar in shape to the holewherein a press-fit interference of the second memberrelative to the holeof the first memberis set to 0.1 mm or more; wherein the second memberis pushed against the holeof the first memberunder a predetermined pressure and at the same time an electric current is applied between the two members to generate electric resistance heat in faying portions of the two members to forcibly push the second memberinto the holethereby forming a joint interface between the second memberand the inner wall surface of the holewherein the joint thus formed is a solid-state welded joint.

Press-fit joint structure

An input circuit has a differential amplification circuit which converts a differential signal to a single end signal to output the single end signal, an attenuation circuit which attenuates a first input signal to output the attenuated signal to the differential amplification circuit, a capacitor in which one end thereof is connected to a first input terminal to which the first input signal is inputted, and another end thereof is connected to an output side of the differential amplification circuit, a buffer to which the single end signal outputted from the differential amplification circuit and a signal transmitted through the capacitor are inputted, and which outputs the output signal, and a feedback circuit which outputs a signal based on an output signal outputted from the buffer and the second input signal to the differential amplification circuit.

Differential amplification input circuit
