Title: Pitch controller of variable pitch propeller
Inventor: MORIYA YOSHITO
IPC: B64C11/30
Filed: 1990-04-25
Abstract: PURPOSE:To constantly generate the maximum thrust at the throttle rate controlled by a pilot so as to enhance controllability by controlling the pitch of a variable pitch propeller so that a detected engine speed equals the maximum thrust speed. CONSTITUTION:Detection signals output by sensors 31 to 35 are input to a microcomputer 36 and a control signal indicating whether or not an exciting current is passed through each of the solenoids (a), (b) of a solenoid flow rate control valve 23 is output to the microcomputer 36. When an engine is started the CPU of the microcomputer 36 reads an engine speed NEO detected by the engine speed sensor 34, and when the engine speed is different from the maximum thrust speed calculated, controls the solenoids (a), (b) of the solenoid flow rate control valve 23 within a pitch control routine and varies the pitch of the blade 15 of a variable pitch propeller 10 by means of hydraulic control. As a result, the engine speed is so controlled as to approximate the maximum thrust speed and the maximum thrust can be generated during navigation.

Title: Detour path setting system
Inventor: KOMINE HIROAKI
IPC: G06F11/20
Filed: 1991-05-15
Abstract: PURPOSE:To set a detour path even in the case of plural link faults or node faults concerning the detour path setting system to set a communication path by detouring a fault point generated in a network. CONSTITUTION:A node 1 detecting the communication fault broadcasts an identifier D of an adjacent node 4 connected to a link 8 detecting the communication fault by a search message (s). A node 3 receiving the search message compares the identifier D in the search message with an identifier stored in its own node ID storing means 3b or an adjacent node ID storing means 3c. As the result of the comparison, since the D stored in the adjacent node ID storing means 3c is matched with the identifier D in the search message, a response message (r) for setting the detour path is returned to the node 1 detecting the communication fault. The node 3 transmitting this response message (r) and the node 1 receiving it set the detour path.

Title: Refresh address generating circuit
Inventor: TAKANASHI SHUICHI
IPC: G11C11/406
Filed: 1985-05-23
Abstract: PURPOSE:To easily detect the trouble of a counter means which generates a refresh address signal by connecting a register means to the counter means, subtracting the value of the output of the register means from the value of the refresh address signal by a subtracting means, and comparing the value of the subtracting means with a constant value by a comparing means. CONSTITUTION:For example, the counter means 1 becomes faulty and the value of the refresh address signal 12 is not increased by one even when a clock signal 11 rises. In this case, even when the value of a register signal 14 is subtracted from the value of the refresh address signal 12, the subtraction result signal 15 is not '1', so the subtraction result signal 15 is a value other than '1'. Consequently, a counter trouble signal 13 outputted by the comparing means 4 indicates dissidence.

Abstract: PURPOSE:To avoid the misoperation of an antilock breaking system by a method wherein, when an overvoltage in supplied by a power supply, the overvoltage is absorbed by an overvoltage absorbing circuit which is connected between a power supply line and an output forbidding means and the output forbidding means is protected from the supply of the overvoltage. CONSTITUTION:In an antilock breaking system, when an overvoltage is supplied by a power supply, the supply of the overvoltage to an output forbidding device 3 is restricted by a resistor 6 and a Zener diode 5 which are connected to a power supply line 100. At that time, an output forbidding signal 102 is outputted from the output forbidding device 3 in accordance with the overvoltage detection signal 104 of an overvoltage detecting circuit 2 and an output circuit 4 does not outputs a driving signal for an actuator 8. Further, a reverse current from the output circuit 4 to the output forbidding device 3 is blocked by an inverter 7. With this constitution, even if an overvoltage output is inputted to a CPU 1, the output is securely forbidden by the output forbidding device 3 and, moreover, the output forbidding device 3 itself is protected from the overvoltage by an overvoltage absorbing circuit 10 and the inverter 7.
