Title: Zero-point-draft compensating device of torque sensor
Inventor: NAKAMOTO AKIRA
IPC: G01L3/10
Filed: 1991-07-29
Abstract: PURPOSE:To make it possible to compensate for zero-point drift readily by solving the simultaneous equations obtained from both detected outputs when the exiting side of a torque sensor is excited under two different exciting conditions. CONSTITUTION:Torque detecting sensitivities alpha1 and alpha2 when exciting currents are i1 and i2, difference in carrier voltages V01 and V02 (V01, V02=V1-V2) when the exciting currents are i1 and i2 under the zero torque and (k) at V02=kV02 are stored in a memory 23 beforehand. When torque T is applied on a transmitting shaft 1, switches 10 and 12 are selectively closed with a CPU 22. The zero-point drifting amounts when an exciting coil 4 is excited with the exciting currents i1 and i2 are made to be DELTAV02 and DELTAV02. When, simultaneous equations are obtained. The equations are solved, and the torque T=1/(alpha2=alpha1k).{(V1-V2)i=i2-k(V1-V2)i=i1} is obtained. The outputs of an A/D converter 20, which are (V1=V2)i=i1 and (V1-V2)i=i2, are inputted into the CPU 22. Then, the value of the torque T wherein the zero-point drift amount is removed can be obtained.

Title: System degradation system at the time of system abnormality
Inventor: OKADA KAZUO
IPC: G06F9/48
Filed: 1992-07-15
Abstract: PURPOSE:To provide a system which can be continuously operated without being reset, in which the frequency of the generation of the abnormality of the system can be reduced while the function of the system is degraded by separating a defective task at the time of the abnormality of the system. CONSTITUTION:When the information of the existence of a certain task is not transmitted, and the system is reset, a watchdog timer monitoring task 8 writes the name of the task and the frequency in an abnormality log table 9. After the system is reset, an initializing task 5 prevents the task whose frequency of runaway is high and the related task from being activated by referring to a task related table 6 and the abnormality log table 9. Thus, the continuous operation can be attained by reducing the reset frequency of the system even when the function as the entire system is degraded.

Filed: 1988-07-28
Abstract: PURPOSE:To achieve an online testing without use of a costly tester by arranging a test pattern generation means responding to an external command, an error detection means and a means for holding an output pattern during the detection of an error. CONSTITUTION:In an offline testing, a test pattern s applied to a circuit 3 to be inspected from a test pattern generation circuit 2. A self-inspection circuit 4 sets an error flag at a register when abnormality is detected and finally, the flag is read out to finish a testing. In an online testing, an ordinary pattern is applied to the circuit 3 to be inspected. A register 50 inputs a data from an input line 51 and an ANDing between an output of a clock input line 52 and an output of the register 50 is given as clock input. Normally, the register 50 is '0' and with the detection of an error, when '1' is developed once in the data input line 51, the register 50 holds '1'. This enables execution of an online/offline test alternatively by a command from outside and of an offline testing with a limited overhead.

Abstract: PURPOSE:To miniaturize a fender by forming a hollow impact support section made of rubber or the like into a divergent shape from an impact reception section to a fitting section side, forming a dog-legged crease at a specific position, increasing the initial reaction force, and increasing the absorbed energy. CONSTITUTION:When an impact support section 2 is initially deformed in the initial stage of coming alongside a quay, the resistance force against the outward swelling of the impact support section 2 is generated by a divergent dog-legged crease 4 and an expanded diameter section 5 provided on the outside of the impact support section 2, and reaction force is increased. When the deformation of the impact support section 2 further progresses, swelling occurs, and the maximum deformation point is attained through the constant reaction force area. The angle theta of the crease 4 is preferably set to about 160 deg. or above. When the angle theta is 160 deg. or below, the impact support section 2 is not swollen outward, and the excessive reaction force having no constant reaction force area is generated. The position of the crease 4 is set to the range of 0.3-0.6 from a fitting section 3 against the total height so as to generate the resistance force against the outward swelling of the impact support section 2. The energy absorbing capability in the initial stage of coming alongside a quay can be increased, and this fender can be miniaturized.
