Title: Air-fuel ratio controlling apparatus for internal-combustion engine
Inventor: HIBINO MASAHIRO
IPC: F02D41/14
Filed: 1983-02-17
Abstract: PURPOSE:To lower the specific fuel consumption of an internal combustion engine without causing degradation of the engine performance and increasing of noxious components in the exhaust gas, by cancelling feedback control of fuel and executing open-loop control such that the air-fuel ratio of mixture is kept leaner than the theoretical air-fuel ratio at the time when the engine is locked up. CONSTITUTION:When an engine is not locked up, a control circuit 10 supplies fuel by opening an injection valve 9 according to the operational conditions of the engine, and the air-fuel ratio of mixture is kept at the theoretical air-fuel ratio on the basis of feedback signal from an oxygen sensor 8. On the other hand, when the engine is locked up at the medium- or high-speed region, a lock- up detector 12 produces an ON-signal. In response thereto, the control circuit 10 cancels its feeback control and executes open-loop control based on output signals of means for detecting operational conditions of the engine. With such an arrangement, it is enabled to lower the specific fuel consumption of the engine without causing degradation of the engine performance and increasing of noxious components in the exhaust gas.

Title: Health check system
Inventor: SHOJI YOSHIAKI
IPC: G06F19/00
Filed: 1995-02-14
Abstract: PURPOSE: To perform health check matched with processing conditions intrinsic to respective equipments. CONSTITUTION: A control part 11 compiles the statistics of response time for the respective equipments 2a and 2b and sets response standby time. A health check data is prepared by a transmission part 12 and transmitted from a communication processing part 21. When a communication processing part 21 receives data, the control part 23 requests the origination of response data and the communication processing part 21 transmits the data prepared by a transmission part 24. When the communication processing part 13 receives the response data, the control part 11 shortens or extends and updates the response standby time when the response time is within the response standby time and judges that the equipment 2a is not normal when no response is present within the response standby time.  By performing that for the respective equipments 2a and 2b, the check matched with processing loads intrinsic to the equipments is performed.

Title: Controller for twist pitch of blades of propeller
Inventor: MATSUO YOSHIKUNI
IPC: B63H1/28
Filed: 1983-02-17
Abstract: PURPOSE:To reduce the vibratory force on the blades of a propeller, by continuously changing the twist pitch of the blades, periodically in every rotation, depending on the distribution of flow velocity at the blades. CONSTITUTION:When piston rods 115 are slid in the axial direction of a propeller shaft 101, pistons 114 send working oil under pressure through passages 122, 123 to the chambers of cylinders 106 divided by first pistons 107, to move the first pistons forward or backward. The motion of the pistons 114 is thus converted into that of the other pistons 107. Since the pistons 107 are slid in the axial direction of the propeller shaft 101, piston rods 108, hinges 111, arms 109 and propeller blade shafts 110 constitute piston-crank mechanisms to turn propeller blades 104 about the propeller blade shafts 110 to change the twist pitch of the blades.
