Title: Method and apparatus for automatic detection of target signal
Inventor: TAKAHASHI SATOSHI
IPC: G01S7/526
Filed: 1996-05-13
Abstract: PROBLEM TO BE SOLVED: To enhance the detection rate of a target signal and to reduce incorrect warning rate by a method wherein the target signal is detected two times by using a frequency analysis, a signal which seems to be the target signal is detected in a first detection and whether the signal is the target signal or not is judged in a second detection. SOLUTION: A signal which is received by a transmitter-receiver 1 is input to a signal processing part 2 so as to output a time-series signal at an amplitude value. A primary detection part 3 performs a frequency analysis to the time- series signal at the amplitude value, it detects an echo signal from an object which seems to be a target, anti it calculates a signal section in which the echo signal exists. Then, a signal delay part 4 delays the time-series signal at the amplitude value, and it fetches the time-series signal at the amplitude value in a section corresponding the signal section which is calculated by the primary detection part 3 and in which the echo signal exists.  Then, a secondary detection part 5 performs a fine-resolution frequency analysis to the fetched time-series signal at the amplitude value, it judges by which object an obtained frequency pattern is reflected, and it outputs a judged result to a display part.

Title: Magnetic head driver
Inventor: KISO MATAICHIRO
IPC: G11B21/02
Filed: 1986-05-23
Abstract: PURPOSE:To obtain a magnetic head driver which gives a less vibration produced when a head is moved by the drive of a stepping motor and to position the head at high speed, by applying a control signal to driving circuit for stepping motor to suppress vibrations. CONSTITUTION:When vibrations are produced when a head 6 is positioned, the voltage proportional to the vibration speed is detected by a speed type generator 8 and amplified by an amplifier 9. This amplified signal contains also such noises undesired for suppression of vibrations and these noises are deleted by a band pass filter 10. The center of the filter 10 is turned to the frequency of vibrations and therefore only the vibration component is extracted with high efficiency. The extracted vibration component is inputted to a driving circuit 11. Then the head 6 is moved onto a designated track position by the track command signal received from a computer connected to the circuit 11. At the same time, the generation of vibrations is suppressed.

IPC: H04L29/02
Filed: 1990-05-07
Abstract: PURPOSE:To reduce the entire transmission time by reading a data in the unit of a byte and sending the data immediately so as to result in sending data of a large data string at once. CONSTITUTION:A transmission fault detection information decision transmission means 13 takes exclusive OR of transmission control information and latches the resulting byte. Then a data string transmission means 14 reads the data string written in a data storage means 11 in the unit of a byte and sends it as a DATA 18 immediately. In this case, the transmission fault detection information decision transmission means 13 takes exclusive OR in the unit of a byte of the sent DATA 18 and latches it simultaneously. Finally, the transmission fault detection information decision transmission means 13 sends a latched data EDC 19 being the exclusive OR from a data NAD 15 to the final value of the DATA 18 having so far been sent. Thus, even when a data string sent from a data transmitter 9 is large, the data string is entirely received by a data receiver 10.

Abstract: PURPOSE:To determine a collision in the early stage of a G signal which is generated at the time of the collision, and to develop an air bag earlier. CONSTITUTION:The correlation of the differential values of G signals detected by a G sensor mounted on a vehicle and G correlation are respectively calculated at a dG/dt correlative value calculating part 4 and a G correlative value calculating part 6.

Abstract: PURPOSE:To perform an extremely good variable speed reproduction without increasing the number of heads by providing a means for time base extending a video signal reproduced by a pair of rotating heads for one field unit. CONSTITUTION:At the time of the reproduction, a switch 21 is connected to an A side and the video signal outputted from a reproducing signal processing circuit 41 is outputted from a terminal 22 through a time base converter 20.
