Patent JP-H0479642-A (JP)
Title: Multi-port optical transceiver
Inventor: KONDO TOSHINORI
IPC: H04L12/44
Filed: 1990-07-23
Abstract: PURPOSE:To quickly detect the possibility of a collision occurring by providing a collision detecting means, pattern signal generating means, a code rule viola tion detecting means and inhibiting the sending of transmitting data from a terminal device when the code rule violation detecting means detects a code rule violation. CONSTITUTION:Upon receiving an optical signal, a light receiving section 21 converts the optical signal into an electric signal and sends the electric signal to a switch 20 and code rule violation(CRV) detector 22. When the detector 22 detects a code rule violation in the received signal, the detector 22 discriminates that a data collision occurs and sends a collision detecting signal CD1 to a collision controlling section 23. When the signal CD1 becomes active, the section 23 outputs a collision displaying signal CD. Then the signal CD is sent to a unipolar/bipolar converters 16a and 16b and further sent to terminal devices from collision displaying lines 13a and 13b through interface sections 11a and 11b. Therefore, the data collision is informed to each terminal device and sending of the transmitting data is inhibited at each terminal device.

Title: Reverse power supply preventing circuit
Inventor: MASUO YASUHISA
IPC: H02H11/00
Filed: 1989-07-26
Abstract: PURPOSE:To supply a circuit with source voltage with small voltage drop by inserting a switch means having small voltage drop between a power supply terminal and the circuit to be supplied with power, judging the polarity of the power supply and controlling the switch means. CONSTITUTION:A reverse power supply preventing circuit X is inserted between a power supply terminal 1 and a circuit 2 to be supplied with power and power supply is blocked when the power is supplied with reverse polarity to the power supply terminal 1. In this case, switch means 3 having small voltage drop, for example, a transistor, is inserted between the power supply terminal 1 and the circuit 2. The switch means 3 is controlled by the output from a polarity judging means 4 for judging the polarity of the power supply. That is, the switch means 3 is turned on when the power supply has a forward polarity and turned off when the power supply has a reverse polarity. Thus, power supply is blocked and the circuit is protected against damage.

Abstract: PURPOSE:To prevent blockage inside a casing due to sticking powder and any damage to a rotor from occurring, by installing a scraper, coming into contact with an outer surface of the rotor, at the outflow port side of the casing inside. CONSTITUTION:When a rotor 13 is rotated, powder enters a feed room 18 from an inflow port 12, transferred inside a casing 11 with rotation of the rotor 13, and then it is fed to an outflow port 14. When the powder contains moisture and has strong properties of adhesive strength, the powder is possible to stick to an outer surface 13a of the rotor 13, but this sticking powder is made contact with the outer surface 13a of the rotor 13 and scraped down by the attached scraper 35 and dropped to the side of the outflow port 14. And, during rotation of the rotor 13, a leakage of the powder inside the casing 11 is kept off by a pair of side rings 17, but if the powder is leaked after passing through these paired side rings 17a and 17b, this leakage of the powder is doubly prevented by a pair of oil seals 19a and 19b.
