Title: Abnormal transmission stop circuit for transmitter
Inventor: KURISU GIICHI
IPC: H04B1/44
Filed: 1994-01-21
Abstract: PURPOSE:To prevent unwanted radio waves from being discharged by circuit abnormality by detecting the transmission current of a transmitter and generating a transmitting function stop signal when a current value exceeds a threshold value. CONSTITUTION:An abnormal transmission stop circuit 25 is constituted of a current detection circuit 26 for detecting the current to be supplied from a power source to a transmission amplifier 8 and a comparator 27 for comparing the detected current value of the current detection circuit 26 with the threshold value. When the detected current value exceeds the threshold value, the transmission is stopped by feeding back it to a base band signal processing circuit 4. When any abnormality is occurred at the transmitter and the spectrum of a transmitting signal is spread, the sum of the energy of spectrums, namely, transmission power is extremely enlarged, and the current supplied from the power source to the transmission amplifier 8 is made more than double as high as a normal operation. Therefore, the abnormal transmission can be stopped by monitoring the detected current value of the current detection circuit 26.

Filed: 1982-01-20
Abstract: PURPOSE:To improve a generating efficiency of a DC magnetic field of a magnet and to miniaturize and lighten a device, by a method wherein a transmitting and receiving coil is mounted  to one leg of a core, formed in a U-shape in cross section, of which a DC electromagnet consists, and a DC exciting coil is wound around the leg, whereto the transmitting and receiving  coil is attached, in the proximity of the transmitting and receiving coil. CONSTITUTION:A transmitting an receiving coil 17 is mounted to a one leg, i.e., a leg 3 of a  core 5, formed in a U-shape in cross section, of which a DC electromagnet consists, and a DC  exciting coil 6 is wound around the leg 3, whereto the transmitting and receiving coil 7 is attached, in the proximity of the transmitting and receiving coil 7. A conventional device, in  which the DC exciting coil 6 is located to a yoke 5, needs 6000 AT in order to generate a magnetic field of 2 Tesla, meanwhile, if the DC exciting coil 6 is mounted to the leg 3 of the core  whereto the transmitting and receiving coil is attached, a magnetic flux density of 2 Tesla is generated by a magnetomotive force of 4000 AT. That is, a similar magnetic field is produced  by an electromotive force mu of the DC exciting coil 6 being 67% (=4000/6000) of that of the  conventional device and a calorific value H being 44%[=(4000/6000)<2>]of that of the conventional device. The weight of the DC exciting coil is determined by the calorific value, the weight of the DC exciting coil is reduced to about 44%, the miniaturization and lightening of  the DC exciting coil also miniaturizes a core part around which the DC exciting coil is wound, which results in permitting the reduction in weight by about 50% on the whole.

Title: Transmission system for hand-written telautogram
Inventor: TANAKA YUKIO
IPC: G08C21/00
Filed: 1978-01-23
Abstract: PURPOSE:To reduce the amplitude fluctuation at the transmission line as well as to secure the  transmission in the narrow band by giving the AM modulation to the Y signal via the X signal  and in the form of the carrier wave for transmission and reproducing the X signal through FM  demodulation after AM demodulation at the receiver side. CONSTITUTION:Y signal fy generated at telautogram signal generator 11 is turned to the carrier  wave and then AM-modulated 17 via X signal fX to be transmitted to transmission line 13. At the  receiver side, amplitude limitation 18 is given to fy to remove the AM component with FM demodulation 19 given next. Thus, the voltage or current Y corresponding to the position of the Y  coordinates is drawn out. While at AM demodulator 21, the received input signal is AM-demodulated, and the output undergoes FM modulation at fx demodulating FM demodulator 15 to  botain the voltage or current X corresponding to the position of the X coordinates. The spectrums are only fy (fy1<= fy<=fy2) and fy + or - fx which is obtained by giving AM modulaion to  fy with fx(fx1<= fx<=fx2) on line 13. Thus, the necessary transmission band features (fy2 -  fy1) + 2fx2 and the band can be narrowed if the necessary band fluctuation is ignored by shifting  the pen on the coordinates.

IPC: B60K17/00
Filed: 1988-01-14
Abstract: PURPOSE:To gain the merits of both the torque split control and the rear wheel steering control by comparing the actual lateral acceleration rate and a computed virtual lateral acceleration rate during the front wheel steeling time, compensating and controlling the distribution of driving forces to the front and rear wheels and the steering angle of rear wheels when a difference between both the above acceleration rates is over or under the specified value. CONSTITUTION:A controller 29 computes a virtural lateral acceleration rate using the data of front wheel steering angle and a car speed at the steering time and compares said virtual rate with an actual lateral acceleration rage detected by a lateral G sensor 28. When a difference between both said acceleration rates is higher than the set value epsilon, the vehicle is evaluated to be in a tendency to the spinning state so that the distribution rate to front wheel driving forces and the steering angle of the same phase direction for the rear wheels are corrected to become high. According to the total driving force, the distribution rate to the front wheel driving force and the steering angle of the same phase direction for the rear wheels are controlled correctly. When a difference between both the acceleration speeds is lower than the set value -epsilon, the vehicle state is evaluated as the drift state, on account of which the distribution rate to the rear wheel driving force and the steering angle of the same phase direction for the rear wheels are corrected to higher and lower, respectively. According to the total driving force, the distribution rate of driving force for the rear wheels and the steering angle of the same phase direction for the rear wheels are controlled correctly.
