Title: Method for creating involute curve
Inventor: ITO KOJI
IPC: B23Q15/00
Filed: 1986-11-05
Abstract: PURPOSE:To shorten a program by controlling a tool feeding speed so that a tangential direction relative speed to a work is fixed at a constant value. CONSTITUTION:In case of creating an involute curve on the work, the work is rotated around a rotating axis determined as the center O of a basic circle for the involute curve to be created and a tool is fed along a tangential line brought into contact with a point of the circumference of the basic circle. It is defined that the radius of the basic circle is r0, a distance from a contact point between the basic circle and the tangential line up to the tool is y, a rotational angle of rotation angle defining the straight line connecting the center of basic circle and the contact point as standard is theta, and a differential mark is d/dt. The rotational angular velocity of the work and the feeding speed of the tool are controlled so that relative speed of the tool in its tangential direction to the work is set up to a constant value V0, i.e. dtheta/dt=(v0/r0)1/theta and dy/dt=r0(dtheta/dt) are formed. Consequently, the working program can be shortened and the formation of the program can be simplified.

Title: Zero point learning device for torque sensor
Inventor: KASHIWABARA MASUO
IPC: F16H59/16
Filed: 1990-10-03
Abstract: PURPOSE:To maintain the extent of detection accuracy in output torque by installing an input shaft rotation detecting means, an output shaft rotation detecting means, a nonneutral detecting means and a zero point learning means, respectively. CONSTITUTION:An input shaft rotation detecting means detects the input shaft rotational speed of a hydraulic torque converter, and an output shaft rotation detecting means detects the output shaft rotational speed of the hydraulic torque converter as well. Pn the other hand, a nonneutral detecting means detects a nonneutrality in a transmission where motive power is transmitted via the hydraulic torque converter. In addition, a zero point learning means learns a point of time when the input shaft rotational speed and the output shaft rotational speed of the torque converter are almost equal to each other as a zero point of the detected torque through a torque sensor detecting an output shaft torque of the transmission, when a fact that it is the nonneutral is detected, and the input shaft rotations speed is zero. With this constitution, detection accuracy in the torque sensor is maintainable.

Filed: 1992-08-21
Abstract: PURPOSE:To remove foreign materials by detecting overload and driving a mud-collecting plate by a specified way, when the foreign materials are bitten in the inlet device and the mud-collecting plate and the motor is overloaded. CONSTITUTION:When inlet cutters 5b are hindered in these rotation due to foreign materials, the overload is detected by an ammeter 9a of a motor 9 rotating the inlet device 5 and the clutch 15a is isolated to release the rotation of mud-collecting plate 11. Next, an instruction from a sequence-controller 30 is transmitted to a motor 15 to rotate the mud-collecting plates 11 faster than the cutters 5b. In this time, the auxiliary cutters 11a of the mud-collecting plates 11 catch up with the cutters 5b by these rotation to remove foreign materials existing between them. After it is detected by the ammeter 9a, the mud-collecting plate 11 is returned to a specified position and fixed to operate again. In this way, overloaded conditions can be rapidly cancelled and damages of the device can be prevented, and the efficiency of maintenace and dredging operation can be increased.

IPC: G06Q50/28
Filed: 1997-09-29
Abstract: PROBLEM TO BE SOLVED: To reduce total cargo handling cost by automatically setting a cargo handling plan, calculating the dispatch money and demurrage fee for a ship, outputting the cargo handling plan of the whole port and the dispatch money and demurrage, and performing the procedure again based on the sailing plan when the sailing plan is corrected. SOLUTION: In preparing the total cargo handling plan, for example, a charge such as an arrangement plan is prepared from the automatically set cargo handling plan of each ship. The results of the operation (the simulation results) are displayed. When operators look and regard the simulation results to be inappropriate, a correction of the sailing plan is prepared, and inputted as the correction of the sailing plan. When the correction of the sailing plan is inputted, the procedures after the preparation of the cargo handling plan are performed again to display a new simulation result. Since not only the cargo handling plan but also the dispatch money and demurrage is calculated and outputted, it can be monitored whether or not the automatically set cargo handling plan is appropriate.

Patent JP-H10112653-A (JP)
Title: A/d converter circuit
Inventor: WADA AKIRA
IPC: H03M1/38
Filed: 1996-10-07
Abstract: PROBLEM TO BE SOLVED: To obtain an A/D conversion result with high accuracy by using a comparison means to compare a highest reference voltage resulting from capacitance division with a 2-division voltage and correcting the 2-division voltage to approach the 2-division voltage to the highest reference voltage resulting from capacitance division. SOLUTION: A 1/2 VAREF resulting from a VAREF through capacitance division at initializing is compared with a VHALF obtained through division resistors. In the case of 1/2 VAREF>VHALF, since an input voltage to an AMP 11 is increased more than a Vthe at initializing, its output goes to H. An output of the AMP 11 via an inverter 13 goes to L, which is given to an F/F 15, and an L level signal from the F/F 15 is outputted to a transistor(TR) 17. Since the TR 17 is conductive as a result and a TR switch 1 and a resistor connected in series are bypassed, a resistance between the VHALF and the VAREF is decreased, the VHALF approaches a 1/2 VAREF, and a a closest reference voltage is detected and then A/D-converted.
