The processing circuitry calculates an attitude using the selected attitude calculation mode.

Abstract: A rotation sensor includes a rotation detector mounted on a holder which is in turn inserted in a casing through its opening. A cover is formed by molding a resin so as to cover the opening of the casing and the portion of the holder protruding from the opening of the casing. A pair of relay terminals extend through a base portion of the holder and a gap defined in the holder, are fixed to a support wall, and connected to respective lead pieces of the detector. A resin cover is formed by molding a resin. When forming the cover, pressure is applied to the holder, thereby causing the holder to bulge axially in the holder. This in turn pushes the relay terminals in the axial direction. But since the relay terminals are fixed to the support wall, the support wall will absorb such pushing force, thereby preventing such pushing from being transmitted to the detector. In order to more effectively absorb such pushing force, the relay terminals may be provided with bent portions in the gap.

Abstract: A rotation detection sensor, which is a wheel-speed sensor, has a detection unit placed in a metal capped cylindrical casing and a holder fit in an opening of the casing. A flange is provided along the entire edge of the opening of the casing. Between the flange and the holder, a viscoelastic liquid gasket is entirely applied. The edge of the opening of the casing and the exposed part of the holder are covered with a resin portion. Thus, the viscoelastic liquid gasket smoothly enters the gap between the casing and the holder to ensure the gap is closed. Moreover, since the viscoelastic liquid gasket is quickly cured owing to its solvent which is speedily volatilized, the gasket exhibits a good workability. Then, after the solvent is volatilized, a rubber-based elastic sealing material is produced. The sealing material thus withstands any temperature change without problem, it never occurs that the sealing material melts to leak out, and the sealing between the casing and the holder can be ensured.

Abstract: A rotation detection sensor, which is a wheel-speed sensor (21), has a detection unit (7) placed in a metal capped cylindrical casing (1) and a holder (2) fit in an opening (1a) of the casing (1). A flange (11) is provided along the entire edge of the opening (1a) of the casing (1). Between the flange (11) and the holder (2), a viscoelastic liquid gasket (sealing material) (12) is entirely applied. The edge of the opening (1a) of the casing (1) and the exposed part of the holder (2) are covered with a resin portion (4). Thus, the viscoelastic liquid gasket (12) smoothly enters the gap between the casing (1) and the holder (2) to ensure the closedness between the casing (1) and the holder (2). Moreover, since the viscoelastic liquid gasket (12) is quickly cured owing to its solvent which is speedily volatilized, the gasket exhibits a good workability. Then, after the solvent is volatilized, a rubber-based elastic sealing material is produced.

Abstract: An ultrasonic wave that is transmitted from an ultrasonic-wave transmitter 1 is received by an ultrasonic-wave receiver 2, through a sheet 4. A reception signal is input to an extracting unit 19. The extracting unit compares its phase with a phase of a reference signal output from a reference-signal reproduction unit 18. It converts a phase difference therebetween into a signal having a level corresponding to the phase difference. The signal having a level corresponding to the phase difference is compared with a threshold value set in a threshold-value setter 20, by a comparator 21. When one sheet 4 is fed, the comparator 21 produces a signal of high level. When a doubles feeding occurs, it produces a signal of low level.
