Title: Ground vibration measurement method and measuring system
Inventor: SATO YOICHI
IPC: G01V3/28
Filed: 1999-07-09
Abstract: PROBLEM TO BE SOLVED: To make accurately investigable an underground structure by calculating a phase speed from the peak vector of a wave number spectrum that is obtained by phase error correction data at each frequency of a vibration sensor being installed at a plurality of points. SOLUTION: A sensitivity sensor 10 has directivity along a sensitivity axis in the direction of a vibration member 15 being extended from a post 11 of the sensor body 11, and is installed at a plurality of points in a target area. When the vibration of the perpendicular component of Rayleigh waves reach the vibration sensor 10, it is converted to an electrical signal according to the change in magnetic flux from a permanent magnet 12 passing through a coil 16. The phase error of each frequency of the electrical signal being generated due to the change in the Rayleigh waves caused by the arrangement angle of the vibration sensor 10 is obtained and is determined. Then, correction is made by a specific numeric expression based on the phase error, thus obtaining a wavenumber spectrum that only a pure phase difference contributes to.  A peak wavenumber vector for maximizing the wavenumber spectrum is obtained and an accurate phase speed at that frequency is calculated by the specific numeric expression.

Title: On-vehicle acoustic equipment
Inventor: KOBAYASHI KOZO
IPC: H04S1/00
Filed: 1991-07-11
Abstract: PURPOSE:To improve the availability of the power supply of a power amplifier and also to decrease the number of transmission cables between a head unit and the power amplifier without causing any crosstalk between them. CONSTITUTION:In regard of a head unit 12, the phase are set opposite to each other between the amplifiers 24FL/24FR and 24RL/24RR and between the audio signals ASFL/ASFR and ASRL/ASRR of channels F and R respectively. Thus the audio signals that should originally be equal to each other between both channels F and R are transmitted to a power amplifier 14 from the unit 12 in an opposite phase state. Then the total current of the amplifier 14 can be reduced and the availability of a power supply is improved. Furthermore a common earth line is secured for a transmission line 26 which transmits the audio signals of opposite phases between the unit 12 and the amplifier 14. As a result, the impedance of the earth line that causes the crosstalk is cancelled and the number of transmission cables can be decreased.

Title: Rotation signal input unit of computer mounted on vehicle

IPC: F02D41/22
Filed: 1982-11-11
Abstract: PURPOSE:To supply high accuracy rotation signals to a computer mounted on a vehicle even if the rotational speed becomes high, by providing a wave form shaping circuit for varying a time constant and a threshold level of a delay circuit for a crank angle sensor according to the rotational frequency of an engine. CONSTITUTION:A reference crank positon sensor A is provided on a gear 5a having one tooth and a crank angle sensor B on a gear 5b having teeth of two times the number of cylinders. Wave form shaping circuits 76, 77 are different from each other in the delay time constants, but have a similar construction. Angle detecting accuracy is improved by enlarging the delay time constant in low speed rotation and lessening same in high speed rotation to prevent the rotational angle of the crank per delay time from being enlarged even in the high rotation. Also, threshold level in wave form shaping of the delayed output is raised in proportion to the increase of the rotational speed to supply the rotational signal not affected even by the rise of noise level caused by magnetic interference or the like accompanying the increase of the rotational speed.
