Title: Alarm device for start of preceding vehicle
Inventor: INOUE TAISUKE
IPC: B60W30/00
Filed: 1991-05-16
Abstract: PURPOSE:To permit the easy drive in traffic snarl by obviating the need of viewing forward during stop by measuring the distance between an own vehicle and the preceding vehicle, taking out the signal proportional to the distance, judging the signal, and setting a memory when the distance is short, while resetting the memory and transmitting alarm for a certain time immediately after reset. CONSTITUTION:The distance between an own vehicle 2 and the preceding vehicle 1 is measured by a distance measuring device. The distance measuring device measures the distance by transmitting ultrasonic waves 5 and receiving the ultrasonic wave which is reflected by the preceding vehicle and returns. A close distance judging device judges that the preceding vehicle is within a distance of 1-2 m on the basis of the signal proportional to the measured distance. When the preceding vehicle is far over 3-5 m, a remote distance judging device judges this fact. Two results of the judgements are added with the set input terminal and the reset input terminal of a memory 3, and when the distance is less than 1-2m, the memory 3 is set, while if the distance is over 3-5m, the memory is reset. The reset output is inputted into a timer 4, and alarm is transmitted for a certain time.

Filed: 1996-07-22
Abstract: PROBLEM TO BE SOLVED: To obtain a signal cylinder assembly convenient for emergent use, having high operability and capable of attaining sure and quick ignition by inserting the remaining leg parts of one signal cylinder into the notched parts of the other signal cylinder and mutually detachably and temporarily combining both the signal cylinders so as to cover the outer periphery of a cylindrical cover body of the other signal cylinder in an approximately contact state. SOLUTION: In a pair of signal cylinders, the remaining leg parts 42p, 42q of the upper signal cylinder are inserted into the notched parts 41x, 41y of the lower signal cylinder and combined with the lower signal cylinder so as to cover the outer periphery of the cylindrical cover body 35b of the lower signal cylinder in an approximately contacting state. The remaining leg parts 42x, 42y of the lower signal cylinder are inserted into the notched parts 41p, 41q of the upper signal cylinder and combined with the upper signal cylinder so as to cover the outer periphery of the cylindrical cover body 35a of the upper signal cylinder in an approximately contacting state (it is preferable to bring the leg parts 42x, 42y into contact with the cover body 35a but it is also available to cover the cover body 35a in a neighboring state).  Thus a pair of signal cylinders are temporarily combined so as to be mutually detached.

Title: Device for preventing elevator working lamp and pit lamp from being left on
Inventor: ITOU KAYOKO
IPC: B66B5/00
Filed: 1996-08-12
Abstract: PROBLEM TO BE SOLVED: To prevent forgetting to turn off a working lamp or a bit lamp for use in the maintenance and inspection of an elevator hoistway. SOLUTION: When inspection lamp switches 12B, 12C are turned on, a working lamp and a pit lamp are turned on and electricity is fed to an electromagnetic coil 15. A stopper pin 14 is thereby attracted by the electromagnetic coil 15 against the energizing force of a pulling spring 16 and projected from a switchboard 13. Therefore, the stopper pin 14 is made to abut to a locking part 10C, and a cover lid 10 can no longer slide upward from a fully open position. Thus even if operating personnel has forgot to turn off the working lamp in a hoistway, the cover lid 10 cannot be closed and therefore the operating personnel easily notices that he has forgot to turn off the working lamp or the like and can turning them off.

Title: Electromagnetic focus circuit
Inventor: GYOTEN TAKAAKI
IPC: H04N9/28
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of the whole of a circuit by reducing the focus current in the horizontal blanking period and the vertical blanking period when focusing is unnecessary. SOLUTION: A logic circuit 4 substitutes a power switching signal e with the level indicating a low voltage to output it in the blanking period in accordance with a horizontal blanking signal (b). A power switching circuit 5 outputs a high voltage power 6 and a low voltage power 7 by switching in accordance with an output signal (f) of the logic circuit 4. Voltage-current conversion amplifiers 8, 10, and 12 use the output of the power switching circuit 5 and take the horizontal focus signal for each color as the input and convert its value to a current value to transfer it to horizontal focus coils for each color 9, 11, and 13.  In the horizontal blanking period when focusing is unnecessary, not only currents flowing to focus coils 9, 11, and 13 is reduced but also the supply voltage is switched from the high voltage power 6 to the low voltage power 7 by the signal (f) from the logic circuit 4 to which the horizontal blanking signal (b) and the power switching signal (e) are inputted, thereby reducing the power consumption.
