A gas sampling device comprising two venturi tubes (5,6) connected in parallel with each other to a gas passage (4) through which a sample gas flows, a dilution gas passage (8) conducting a dilution gas (g), a downstream side of the smaller one (6) of the venturi tubes being connected to said dilution gas passage, and a constant-flow rate device (11) and a gas sampling passage (12) connected in pa...

A system for correcting a wheel speed data produced by a wheel speed sensor, employs a filter for removing noise contained in the output of the wheel speed sensor. The filter limits variation rate of the wheel speed data so as to avoid occurrence of extraordinary variation of wheel speed as influenced by error factors, such as destruction of the wheel speed sensor or noise superimposed on the outp...

PURPOSE: To provide a computer input device by providing a light source and a photosensor inside a spherical housing oppositely on a shaft passing through a center point, filling the inside with liquid and a gaseous body to half and drawing a rotation angle by the difference of sensor receiving light quantity by the refraction of light at a boundary. CONSTITUTION: When a user holds this computer i...
