  • Patent number: 6039588
    Abstract: Comprising an outside case, an inside case installed rotatably in the outside case, a cable installed in a space formed by the outside case and the inside case, and a guide ring, the guide ring is accommodated in the space so as to abut against elastically. With the frictional resistance between the guide ring and inside case being greater than the frictional resistance of the guide ring and outside case, the guide ring rotates and moves. In this constitution, generation of noise is extremely reduced. Hence, an inexpensive and highly reliable rotary connector is obtained. In particular, this rotary connector is used in a steering device of automobile or the like.

  • Patent number: 5490588
    Abstract: Coin processing apparatus electromagnetically tests an inserted coin, separates genuine coins from counterfeit coins by a first pathway switching mechanism, and stores genuine coins in change tubes and a cash-box by a second pathway switching mechanism, according to the type of coin. The pathway along which the coins pass is provided with pass sensors at two positions therein, where one pass sensor detects the coins and the other pass sensor controls the operation of the second pathway switching mechanism in such as manner as to prevent passing coins from becoming trapped therein. The second pathway switching mechanism is operated after a predetermined time has elapsed from the fall of a detection signal from a pass sensor, to end the flow of current through and thereby prevent overheating of a solenoid therein.

  • Patent number: 5363207
    Abstract: Data produced from a transmission source facsimile are received by a simulated communication circuit network, and thus received data are compressed and temporarily stored into a memory. After the data have been compressed, the data stored in the memory are read out and transmitted to an other party's facsimile via an external communication circuit network. Since the data transmitted to the other party's facsimile via the external communication circuit network are compressed data, a time required for transmission can be relatively shortened. Accordingly, a rapid data transmission can be achieved without the facsimile being replaced by a rapid type facsimile which is expensive. Further, various additional functions of a facsimile can be directly enjoyed from those intrinsically owned by the transmission source facsimile.
