Title: Digging force control device of excavator
Inventor: KOSA TAKAHIKO
IPC: B66C13/32
Filed: 1988-04-28
Abstract: PURPOSE:To improve digging efficiency and accuracy by comparing a digging load detected by a sensor with the set value and controlling the lowering speed of a digging device so that it is slowed down when the digging load is larger than the set value, and the lowering speed is accelerated when the load is smaller than the set value. CONSTITUTION:An optimum digging load is determined by a digging load setting device 39, and set by a setting switch 41. Then, the braking force to be given to a power transmission system is set out by operating a controller 35. Next, a digging device 15 is lowered to sit on the bottom by extending the rope of a hoisting drum 9a, and a load current detected by a digging load current detector 42 is fed back to a control computer 36, and compared with the set value preset by the setting device 39. Further, a control unit 33 outputs a command value foward an electro-hydraulic conversion valve 30 to slacken the braking when the digging load is smaller than the set value, and to increase the braking force when the load is larger than the set value.

Title: Remote travel control method for remotely steered vehicle
IPC: G05D1/02
Filed: 1992-03-31
Abstract: PURPOSE:To secure linearity at the start of a travel by inhibiting the travel device of one of the right and left levers of a transmitter from being turned ON even if the lever slants into a buffer zone when the other lever is in a dead zone, and turning ON both the travel devices when both the levers slant into the buffer zone. CONSTITUTION:When the travel devices 4 and 5 are brought under ON/OFF control for the inclination range of the left and right levers 7 and 8 of the transmitter 2, the dead zone D is determined in consideration of the play of the levers 7 and 8. Further, the buffer zone A is provided closer to an ON area B where a travel command signal turns ON than to an on-vehicle controller 3. Even if one of the levers 7 and 8 slants to the position corresponding to the buffer zone A while the other is in the dead zone D, the travel command signal from the controller 3 does not turn ON. When both the levers 7 and 8 slant to the positions corresponding to the buffer zone A, the left and right travel command signals and, therefore, both the travel devices 4 and 5 turn ON. When one of the levers 7 and 8 is in the dead zone D and the other is in the dead zone D, one of the travel devices 4 and 5 turns ON.

Title: Combustion controlling device
Inventor: SUZUKI KAZUO
IPC: F23N5/18
Filed: 1981-07-03
Abstract: PURPOSE:To prevent incomplete combustion from occurring by a method wherein the blast rate of a blower is forcibly increased when the pressure in a nozzle connecting to the outlet side of a proportional control solenoid valve rises abruptly at the titled device employed in hot water supplier or the like. CONSTITUTION:The pressure in the nozzle connecting to the outlet side of the proportional control solenoid valve 8 is controlled in proportion to the temperature of load (or of water) by means of a burning rate controlling circuit 9 during burning operation. Furthermore, the rotational frequency of a fan motor 1 is also controlled in proportion to the load temperature by means of a blast rate controlling circuit 13 and a fan controlling circuit 2. At this time, when temperature is set higher by a variable resistor for temperature control 10 or water flow rate is increased, said solenoid valve 8 responds immediately to abruptly raise the pressure in the nozzle, resulting in causing sharp change of the voltage at the point B with the conduction of a transistor 6. A forcible blast rate setting circuit 14 detects said change and forcibly increases the rotational frequency of the fan motor 1 through the blast rate controlling circuit 13 and the like.

Title: Speed change control device for automatic transmission
Inventor: TAZAWA MITSUGI
IPC: B60W10/10
Filed: 1986-05-09
Abstract: PURPOSE:To increase degree of freedom of design of a speed change point by performing an upshift speed change by turning off a solenoid temporarily only when a specified period of time has elapsed after a specified vehicle speed is exceeded under a kickdown condition. CONSTITUTION:When acceleration is made with a kickdown switch being off and a set vehicle speed is reached, a 1st timer starts to count time. At that time a solenoid control means turns the solenoid off temporarily and a speed change point of a shift valve switches to a low vehicle speed side to perform an upshift speed change. At the same time, a 2nd timer starts to count time. At that time, the solenoid control means turns the solenoid on by means of a reset means. Since a vehicle speed at this point of time is above the speed change point due to hysteresis of a shift valve, a downshift speed change is not performed. In addition, time lag is not produced when a kickdown is performed under a condition of small degree of throttle opening.

IPC: F02D41/04
Filed: 1988-04-27
Abstract: PURPOSE:To enable the displacement to be decreased of air-fuel ratio following opening and closing action of an auxiliary valve by correcting a fuel supply amount so as to correspond to the actual intake air amount when an opening and closing condition is detected of the auxiliary valve provided in the downstream side of a throttle valve. CONSTITUTION:An auxiliary valve 15, opening and closing an intake passage 7, is interposed in the downstream side from a throttle valve 11, being closed by an actuator 22 in a specific operative condition in the time of low load or the like. Now when a open-close action signal of the auxiliary valve 15 from an opening and closing sensor 29 is input to a controller 26, a fuel supply amount is corrected by a correction signal corresponding to opening or closing action of the auxiliary valve 15. For instance, in the time of acceleration operation opening the auxiliary valve 15 from its closed condition, an asynchronous pulse is output performing correction so as to increase fuel, while in the time of deceleration operation closing the valve from its opened condition, setting of a fuel injection amount being based on a detection signal from an intake amount sensor 9 is stopped, and the correction is performed so as to supply a fixed amount of fuel. In this way, fuel is supplied corresponding to the actual intake air amount.
