Title: Triple-action pressure switch
Inventor: HIROTA HISATOSHI
IPC: H01H35/34
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To enable miniaturization and automated assembly of a triple-action pressure switch by using coil springs as switch energizing means, and energizing contacts using electric switches in a direction opposite to that of driving of a switch drive mechanism. SOLUTION: Electric switches 3, 4 have a pair of fixed contacts 3a, 4a placed in 180 deg. symmetrical positions inside a housing 1, and have movable contacts 3b, 4b which move in the direction of the axis of the housing 1 to touch and leave the contacts 3a, 4a. A compression coil spring 31 is interposed between the contacts 3b, 4b, and a compression coil spring 41 is interposed between the lower surface of a receiving member 59 and the bottom surface of the housing 1. The contact 4b is therefore energized by the spring 41 in a direction opposite to that of driving of a rod 58, while the contact 3b is energized by the springs 31, 41 in the direction opposite to that of driving of a sliding cylinder 57. Further, as driving by a reversal board mechanism 5 becomes weaker, the contacts 3b, 4b are returned to their original positions by the energizing forces of the springs 31, 41.

Title: Communication equipment
Inventor: KOGURE KAZUYA
IPC: H04B10/114
Filed: 1995-09-12
Abstract: PROBLEM TO BE SOLVED: To conduct data transmission after confirming the presence of a communication opposite party available for data signal transmission reception. SOLUTION: A confirmation signal is subjected to ASK modulation and sent to a communication opposite party for each period t1 for a non-transmission period of a data signal. On the other hand, a confirmation signal is sent for each period t1 similarly from the communication opposite party. Upon the receipt of the confirmation signal sent from the communication opposite party, a latch circuit 28 latches the reception confirming signal and provides an output of a status signal representing a valid state. When the latch circuit 28 does not receive a succeeding confirming signal within a period t2, the circuit 28 is reset by expiration of time of a timer circuit 20 and the status signal is invalid. Then the presence of communication opposite party is confirmed with each other during non-data transmission period and only when the presence is clear, the data signal is sent.

Title: Train crash preventing system
Inventor: YATSUGU MASANOBU
IPC: B60L15/40
Filed: 1995-08-22
Abstract: PROBLEM TO BE SOLVED: To eliminate the occurrence of a false operation and to ensure the prevention of the accident of crash of trains on a single track by propagating acoustic waves on rails for communication between the trains and by stopping the trains on the occasion when they come near to each other unnecessarily. SOLUTION: An up train has an acoustic wave transmitter of 1000Hz, for instance, and an acoustic wave receiver which can receive an acoustic wave of 2000Hz, for instance. The train runs on rails while impressing an acoustic wave of 1000Hz on the rails. A down train, the other side of communication, transmits the wave of 2000Hz likewise and runs on these rails while receiving the wave of 1000Hz, When the trains come near to each other, the acoustic wave is received by each of them without being attenuated and the outbreak of the danger of crash can be recognized. When the amounts of attenuation of the received waves are larger than predetermined ones, a distance between the trains is judged to be large enough to be free form the danger of crash and thus they can be operated safely.

Filed: 1992-08-12
Abstract: PURPOSE:To allow discrimination between hot line and cold line by providing a rectifier element connected in series between a voltage detector and a live part detecting circuit, and means for directly grounding to the earth, thereby identifying a cold line subjected to electrostatic induction. CONSTITUTION:A diode 10 is connected between an input resistor 2 and a live part detecting circuit 5 for a resistor 3 at detecting part and a voltmeter 4. When a voltage detector 1 in an inductive decision type electroscope is brought into contact with a power line 6, a micro pulsating current caused by the power line voltage with respect to the ground flows in one direction through the input resistor 2, the diode 10, the detecting part resistor 3, and an earth rod 9 if the power line is in live state and a voltage drop appears across the resistor 3. The voltage drop is detected through the voltmeter 4 and a decision is made whether the power line 6 is in hot state or not. If the power line 6 is in hot state, the voltmeter 4 provides an indication stably otherwise zero is indicated. When the power line 7 is hot and the power line 6 is cold, the power line 6 is subjected to electrostatic induction and the potential rises. When the power line 6 is subjected to voltage detection, voltage drop across the detecting part resistor 3 decreases gradually and finally goes to zero. Voltage drop is detected by means of the voltmeter 4 and discrimination is made between cold and hot lines.

IPC: B60K31/00
Filed: 1995-09-13
Abstract: PROBLEM TO BE SOLVED: To simplify the constitution of a device for traveling at a constant speed. SOLUTION: Electric power is supplied to a motor 27 of an actuator 22 via lead wires 28, 29, limit switches 31,32, and transistors T1 to T4.
