Title: Electric angle detector for synchronous motor
Inventor: YAMADA EIJI
IPC: H02P25/10
Filed: 1997-07-30
Abstract: PROBLEM TO BE SOLVED: To exclude an influence by the change of a filter or change of characteristics, by executing detection of a current value after a predetermined time corresponding to the time constant of the filter is elapsed from the application of a voltage. SOLUTION: A CPU 120 further waits for the elapse of a predetermined detecting period after stopping a voltage application, detects a current value via a current sensor 102, and detects an electric angle by using the current value. And, the period is set so as to satisfy the condition that the period is sufficiently longer than the time constant of a filter 106. Thus, since a time delay is incorporated in the detection of the current and hence the current can be detected without influence by a delay in rise of the current by the filters 106, 108, the angle can be accurately obtained. And, even if characteristics of the filter 106 are changed, a desired current value can be detected. And, the angle can be accurately obtained.

IPC: G01S7/52
Filed: 1990-08-22
Abstract: PURPOSE:To enable an accurate detection to be made regardless of a few samples by interpolating a result of a high-speed Fourier transformation. CONSTITUTION:A maximum level which is included in a result of a high-speed Fourier transformation and a first frequency corresponding to this level and a second frequency with a larger level out of upper and lower adjacent frequencies and the level are determined. Then, level ratio between the first and second frequencies is obtained. When the obtained level ratio does not exceed a reference value, the first frequency is output as the reception frequency. When it exceeds the reference level, a level ratio R of two frequencies, namely the first and second frequencies, is obtained. Then, a coefficient delta is obtained according to an expression to be set based on a level ratio R, the number of samples N of reception signal in a high-speed Fourier transformation, and the coefficient deltawith a value corresponding to a position between samples of the reception signal frequency. A reception frequency is obtained by adding a frequency difference fs/N from a low frequency which is determined by this coefficient delta, a sample frequency deltafs, and the number of samples N to a low frequency.

Title: Method for measuring position and shape of forward abnormal object for shield driving method
Inventor: TANAKA SHOGO
IPC: G01S15/88
Filed: 1994-09-16
Abstract: PURPOSE: To accurately detect a forward abnormal object by finding acoustic wave reflecting points by using the Snell's law about the route of acoustic waves based on the distance found by performing pattern matching between the waveform of signals received from the abnormal object predicted by modeling the waveform of received signals and the actual waveform of the received signals. CONSTITUTION: One transmitter and a plurality of receivers are fitted to the front cutter face of an excavator 1 and distance data are obtained from an abnormal object by transmitting acoustic waves from the transmitter at every appropriate excavating distance and receiving reflected waves from the abnormal object by means of the receivers. The shape of the abnormal shape of the abnormal object is measured and the position of the object is precisely decided by using the Snell's law by taking into account not only the distance between the transmitter and receivers and reflecting points on the surface of the object, but also the routes of the transmitted and received waves considering the reflecting condition at the reflecting points of transmitted wave signals. When the shape of the object is already known, a prescribed formula is optimized one time on the shape.  When the shape is not known, the parameter which gives the minimum estimation is found by applying the method of least squares to each model (slope, sphere,and cylinder).

Abstract: PURPOSE:To attain the communication between slave stations whose line is not faulty even when a fault takes place in a line between a relay station and a base station. CONSTITUTION:A synchronizing signal detection section 306 connecting to an output side of a receiver 302 detects a synchronizing signal sent from a base station. A control section 322 discriminates it that a line fault takes place when no synchronizing signal is detected to start a synchronizing signal transmission section 317 thereby generating the synchronizing signal and it is sent to a subordinate station via a transmitter 304. Furthermore, when a call signal detection section 313 detects a call signal from a slave station, the section 313 starts a time slot allocation section 318 to allocate a time slot. When a dial signal detection section 315 detects a destination number from the slave station, the section 315 references a station information memory 323 to confirm the number and to allocate other time slot to the slave station being the destination. A time slot changeover section 312 selects any of two time slots to implement communication between slave stations.
