Title: Vibrating current collecting/feeding method and device
Inventor: YONEHARA TAKASHI
IPC: B60L5/08
Filed: 1988-12-10
Abstract: PURPOSE:To reduce frictional resistance through point contact by applying fine vibration onto a contact terminal, when current is collected or fed through the contact terminal movable along a conductor, and repeating contact/non- contact with a fixed conductor. CONSTITUTION:A current collecting terminal 9 is in contact lightly with a wire 11 and power is fed through the current collecting terminal 9 to an electric car 1 running on a rail. At this time, a vibrator 6 is operated to vibrate a vibration rod 6a up and down so as to move an insulator 8 and the current collecting terminal 9 vertically with respect to the upper board 7 of a pantograph 5 thus repeating contact/non-contact of the current collecting terminal with the wire 11. Although the pantograph 5 is normally energized to pressure contact with the wire 11, the current collecting terminal 9 vibrates quicker than the pressure contact reaction, thus causing contact/non-contact with the wire 11.

IPC: G01C21/00
Filed: 1996-11-25
Abstract: PROBLEM TO BE SOLVED: To calculate accurate speed and advance direction even if a multi-path signal is received by a GPS receiver. SOLUTION: A signal from a GPS satellite is received by a GPS antenna 101, and an inverse diffusion part 102 takes out a signal where a frequency consists of the error of TCXO and the Doppler shift due to the move of the satellite and a traveling body. The signal is multiplied by the output of NCO 104 at a mixer part 105, is inputted to an NCO control part 106, and control is made so that NCO frequency is equal to the error of TCXO and the Doppler shift due to the move of the satellite and the traveling body.  A calculation part 109 calculates the Doppler shift frequency due to the move of the satellite, an abnormal satellite detection part 108 that received the NCO frequency from the NCO control part obtains the amount of change from the NCO frequency at the last positioning, and judges that the satellite is malfunctioning when the NCO frequency changes more than an acceleration that the traveling body achieves. A positioning part 107 excludes the satellite that is judged to be malfunctioning and performs positioning calculation.

Title: Bar code reader
Inventor: TSUJI NOBUHIKO
IPC: G06K7/10
Filed: 1986-12-27
Abstract: PURPOSE:To improve the accuracy of bar code reading by measuring the scanning angle of a light beam in terms of time to obtain time coordinates within a scanning area of a bar code and correcting the pulse width for each bar based on said time coordinates. CONSTITUTION:A microcomputer 15 decides the presence and the scan end position of a bar code 2 from the output of a 1-shot multivibrator and inhibits a DMA permission signal (h). Then the time difference is obtained between the rise and fall edges for each pulse based on an array of time measurement data. Time conversion is given to the pulse width to arrange said measurement data again. Then the correction value is obtained from a corrected curve based on the coordinates within a scanning area and said pulse width is corrected. Then data are arranged. Thus the code 2 is decoded based on data on each corrected pulse width.

Title: Device for sensing foreign matter in liquid
Inventor: SUZUKI MASAO
IPC: G01N29/02
Filed: 1990-11-21
Abstract: PURPOSE:To sense foreign matters in a liquid precisely by measuring change in the electric admittance of at least two ring-shaped ultrasonic vibrators which are in proximity installation on the inner wall of a conduit pipe. CONSTITUTION:A fluoric resin film is formed on the surface of the conduit pipe inner wall, and at least two ring-shaped ultrasonic vibrators 2a, 2b are in proximity installation in such a way as directly contacting in liquid, and ultrasonic waves are emitted by a signal transmitter 5. Admittance measuring parts 4a, 4b sense eventual foreign matters in the liquid from change in the output voltages of differential amplifiers 6a, 6b, which are based upon change in the admittance value and change in the sonic field formed in the liquid. Thus the vibrators 2a, 2b are arranged in proximity installation to serve for sensing with changing admittance for vibration of the conduit pipe, pressure of the liquid, and change of the density, and it is not likely influenced by the density, temp., and viscosity of the liquid owing to the differential amplifiers 6a, 6b. Thus accurate sensing is actuated only for foreign matters, which ensures that sensing is made with high precision.

Sulfuric acid is recovered from the soln. having a low content of Ti by diffuse dialysis or electrodialysis. An electrodialyzer incorporating a monovalent cation permselective membrane is preferably used in electrodialysis because the intrusion of the impurity metal ions is prevented. The recovered sulfuric acid can be recycled to the Ti production process.
