Title: Vehicle rear monitoring alarm device
Inventor: NUMANAMI TAKASHI
IPC: G01S7/56
Filed: 1996-07-16
Abstract: PROBLEM TO BE SOLVED: To prevent a driver from feeling an uneasiness by flashing a LED by a reflected wave confirming and detecting means when a reflected wave can not be received although an ultrasonic sensor is normal to notify that monitoring of obstruction is normally performed, and changing the LED To emit light according to the distance after the obstruction is detected. SOLUTION: A reflected wave confirming and detecting means 3 detects whether the reflected wave from an obstruction of an ultrasonic wave transmitted from an ultrasonic sensor 1 is returned or not, and flashes one color of LED 6 when it is not returned. An abnormality detecting means 4 detects the state where the ultrasonic wave can not be normally transmitted and received because of the disconnection of the ultrasonic sensor 1, and inputs it to the reflected wave confirming and detecting means 3. The flashing of the LED 6 is performed when this abnormality is not detected. The LED 6 is flashed until an obstruction in the rear of a vehicle is detected, thereby notifying a driver that the monitoring is normally performed. After the obstruction is detected, the LED 6 is switched to change the emitted color to notify of the approaching degree to the obstruction.

Title: Repeater with internal switching function
Inventor: IMAZATO MASAHARU
IPC: H04B7/204
Filed: 1983-11-04
Abstract: PURPOSE:To reduce sufficiently the variance of frequency fluctuation between intermediate frequency signals at the reception section of a repeater used for a multi-beam satellite communication system. CONSTITUTION:A signal of the 1st oscillator 29 and a signal of the 2nd oscillators 30-33 are mixed by mixers 25b-28b, from which local oscillation signals are formed respectively. Each reception signal is mixed by mixing tubes 25a- 28a, where the signal is converted into an intermediate frequency signal. Since the fluctuation of the intermediate frequency signal is dependent on the local oscillation signal, the frequency fluctuation of the oscillator 29 with a large frequency fluctuation appears in each intermediate frequency signal. Thus, the variance in the frequency fluctuation of each intermediate frequency signal is less.

Filed: 1995-08-15
Abstract: PROBLEM TO BE SOLVED: To reduce a moire with minimum resolution reduction by alternately operating a vertical deflecting circuit by a saw tooth wave, which has the time phase shifted by each display mode, to shift the vertical picture position at intervals of a vertical period. SOLUTION: When vertical and horizontal synchronizing signals are inputted, a central processing unit 1 detects their frequencies, and a clock generating circuit 2 generates a reference clock whose frequency is sufficiently higher than the horizontal frequency. In accordance with the indication of the central processing unit 1m a pulse generation circuit 7 generates a pulse, which has the time phase shifted by display modes, based on the vertical synchronizing signal and the reference clock and inputs it to a selector 8. The selector 8 turns on/off a switch 5 of an integrating circuit, and an operational amplifier 3 alternately outputs the saw tooth wave, which has the time phase shifted, to operate a vertical deflecting circuit 10.  Thus, the vertical picture position is shifted at intervals of the vertical period, and not only a moire is reduced with minimum resolution reduction but also complicated design is unnecessitated.

Filed: 1990-08-08
Abstract: PURPOSE:To prevent an edge drop control from overshooting and huntering by conducting a feedforward control based on an edge drop of a plate before rolling and correcting a coefficientue value of a control model successively by feedback. CONSTITUTION:An target edge profile of the outlet side of the final pass of rolling is determined and a deviation from this target value is made a parameter or a dependent variable. Further, a mathematical model where an edge profile parameter before rolling and a shift position of a shift mechanism are independent variables is made previously.
