Filed: 1987-04-28
Abstract: PURPOSE:To raise the burning efficiency by preventing the deposit of pulverized coal in a diverting pipe by providing a separating means such as cyclone separator that separates a predetermined amount of primary air from fuel supplied to a pulverized coal burner nozzle, and an ejector that introduces gas to the furnace outlet side. CONSTITUTION:As pulverized coal carried by primary air spirals around the outer perimeter of a cyclone separator 19, part of the primary air and a small amount of the pulverized coal pass through a sleeve 22 into a vent pipe 20, and the remainder of the primary air and pulverized coal are ejected into the furnace from a pulverized coal burner nozzle 5.

At this time, the vent air speed in the vent pipe 20 becomes lower. A control member 28 is moved to the outside of the furnace to increase the gap in the ejector 25 to allow the air in a windbox 2 to be drawn into a vent burner 23 through the ejector 25 so that the air speed in the vent pipe 20 and vent burner 23 may be higher than the floating speed of the pulverized coal to prevent its deposit.

Title: Protector for system interconnection
Inventor: OKATSUCHI CHIHIRO
IPC: H02M7/493
Filed: 1993-05-07
Abstract: PURPOSE:To detect an islanding condition surely and to stop the operation of an inverter by comparing the line voltages of a single-phase 3-line type AC system and detecting a malfunctioning condition, concerning a device having an inverter which converts DC power to AC power and interconnects to the single-phase 3-line type AC system. CONSTITUTION:A difference voltage detecting circuit 22 detects the voltage difference between the two line voltages of a single-phase 3-line type, i.e., between L1 and a midpoint and between L2 and the midpoint, and a level detector 23 performs level judgment. And if it exceeds a set value, it is judged that malfunctioning occurs, and a time function circuit 24 produces output V24. A value V25 obtained by multiplying this output V24 by the output V11 of an amplifier 11 for amplifying the voltage difference between a voltage reference 10 and a DC power source 1 through the working of a multiplier circuit 25 is inputted to a current reference circuit 12, and the magnitude of an AC current reference V12 is varied. As a result of this, the output current of an inverter 2 varies, and balance with loads 9a, 9b, and 9c is lost, and the voltage and frequency of a distribution line change swiftly. These are detected with a malfunction detecting circuit 19 through a voltage relay 17 and a frequency relay 18, and the inverter 2 is stopped.

Title: Packet exchange equipment
Inventor: ISHIZUKA TOSHIO
Filed: 1987-05-01
Abstract: PURPOSE:To prevent a large delay in a packet other than a multi-address transmission packet by using a bus contention arbitration circuit so as to acquire the transmission right of a bus and then bringing all packet transmitters- receivers into the reception state thereby sending a multi-address packet data at one time. CONSTITUTION:In a multi-address packet data transmitter 12, if a multiple address packet transmission request takes place, a transmission control section 12 checks whether or not all packet transmitters-receivers 111-11N in the packet exchange can receive the multi-address packet transmission data and enters the acquisition operation of a status transfer bus 22 when it is possible. The status transfer bus 22 is acquired by sending a status transfer bus operation request to a bus contention arbitration circuit 26 via a control signal line in the status transfer bus 22 and receiving the operation enable signal thereto. Thus, the multiple address packet data to the packet transmitters-receivers is sent at one time. Thus, the load of the hardware is relieved and the delay in the packet except the multi-address packet is almost unchanged.

Title: Clock checking circuit
Inventor: KURIYAMA MASAHIRO
IPC: G06F1/04
Filed: 1987-04-30
Abstract: PURPOSE:To maintain the normal operations set within a system and to improve reliability of a clock checking circuit by providing a circuit working in response to a clock into each circuit unit of a system terminal and comparing the outputs of these circuits with each other via a common comparator to check the clock. CONSTITUTION:When the working of this clock checking circuit is started, the signals SL and clocks CL are supplied to J-KFF circuits 51 and 52 respectively. Both circuits 51 and 52 produce signals Q1 and Q2 in terms of time series according to the input of the clock CL and under the condition that the logic '1' exists as the signal SL. These signals Q1 and Q2 are equal to each other in a normal operation mode and therefore a comparator 6 produces no error signal SE. In case the clock signal CL supplied to a unit circuit 3 or 3' set at the terminal of a clock distributing circuit is omitted or a false CL is produced due to the external or internal disturbance to cause input of extra clocks CL, both signals Q1 and Q2 are different from each other and therefore the comparator 6 produces the signal SE. THus an error processing sequence is started.
