Title: Coin diameter discrimination device
IPC: G07D5/02
Filed: 1992-03-13
Abstract: PURPOSE:To highly and precisely discriminate the diameter of a coin through the use of a transmission coil and a reception coil without being affected by the shift speed of the coin and without being affected by the conductivity and thickness of the coin. CONSTITUTION:Eddy current is generated in the coin at an alternating magnetic field by the transmission coil 12, and the shift speed and passing time of the coin is calculated from time information obtained from inductive voltage detected by the two reception coils 13 and 14 with the shift of the coin by the magnetic field by eddy current. The diameter of the coin is operated based on shift speed and passing time. The inductive voltage level changes not only by the diameter of the coin but also by thickness and conductivity, but the diameter can accurately be discriminated in spite of the thickness and conductivity of the coin since time information obtained from the inductive voltage depends only on the diameter.

Inventor: NASU YASUSHI
IPC: G01B17/00
Filed: 1991-03-28
Abstract: PURPOSE:To detect a tilt angle and the direction of tilt simultaneously by disposing piezoelectric conversion electrodes set beforehand, in a liquid, for each relative tilt angle to a reference attitude of the surface of a flat-plate solid fixed at a position opposite to a free surface and of the surface of the liquid. CONSTITUTION:In a tilt angle detecting device 10, a piezoelectric plate 12 is provided in the vicinity of the bottom of a liquid vessel 11 wherein a liquid is sealed up so that it has a free surface. On the piezoelectric plate 12, blindlike electrodes 13 for excitation are provided in the shape of concentric circles in the central part thereof, and electrode groups 16 to 19 for reception are provided in sectors I to IV around the electrodes 13 respectively. When a high-frequency signal voltage is impressed on the electrodes 13, a surface wave is generated in the piezoelectric plate 12 and a longitudinal wave in the direction of an inverted cone of a vertical angle 2theta0 is generated in the liquid and received by the electrode groups 16 to 19. When the vessel 11 is tilted and the piezoelectric plate 12 is tilted at an angle theta to the surface of the liquid, distances of arrival from the center O of excitation are different. Since the order of the electrode groups 16 to 19 is so determined as to correspond to the tilt angle theta, however, the tilt angle can be known immediately and the direction of tilt can be known as well from the sectors.
