Title: Vibration damping trolley wire and vibration damping method for trolley wire
IPC: B60M1/30
Filed: 1992-03-10
Abstract: PURPOSE:To restrict the vibration of a trolley wire due to a pantograph at the time of train traveling by fixing a complex body, which is obtained by mutually laminating high rigid thin plates and high polymer visco-elastic layers of rubber group or synthetic resin group, to the upper part of a trolley wire main body. CONSTITUTION:A complex body 12 is tightly fixed along the upper part of a trolley wire 11, which includes a clamp groove 11a, and the complex body 12 is obtained by mutually laminating high rigid thin plates 13 and high polymer visco-elastic layers 14. Bending deformation of a trolley wire main body 11 due to a pantograph of a train or the like deforms the complex body 12, and since the compound body 12 is tightly adhered to the upper part of the trolley wire main body 11 in the nearly same shape, the high polymer visco-elastic layers 14 of the complex body 12 receives the tension and the compression and the shearing deformation, and while friction is generated between the trolley wire main body 11 and the complex body 12. The vibration energy is converted to the heat by this deformation and the friction, and the drive of the trolley wire is restricted to secure the safety of the high speed travelling of a train or the like.

Title: Charge transfer device for synthesization of signal
Inventor: SATOU MAKI
IPC: H04N5/335
Filed: 1982-05-21
Abstract: PURPOSE:To simplify the circuit constitution and to enable the multiplex transmission, by supplying the same clock to both the 1st and 2nd channels and an n-fold frequency to the 3rd channel respectively and then selecting different phases for signal charges which are transferred throgh the 1st and 2nd channels. CONSTITUTION:Dot sequential signals G, R and B supplied from a charge transmitting element CCD21 using a prescribed array of color filters are converted into voltage through an output circuit 22. This converted voltage is separated into green, red and blue signals G, R and B respectively through a signal separating circuit 23. The signals R and B are applied to a simultaneous circuit 24 and converted into a simultaneous signal of both signals R and B. Then signals R and B are supplied to a matrix circuit 25. While the signal G is applied to a charge transfer device 30 and then to the circuit 25 after synthesization of signals. The signal processing circuit of the device 30 is set opposite to a multiplexer, and the signal G is delayed by 1H. Then a delay output and a non-delay output are multiplexed and applied to the circuit 25. In such a way, the circuit constitution is simplified.
