Title: A singular point avoiding method in direct teaching of articulated robot
Inventor: WATANABE KAZUNORI
IPC: G05B19/42
Filed: 1998-02-24
Abstract: PROBLEM TO BE SOLVED: To provide a singular point avoiding method which requires little calculation and can be easily realized, in direct teaching when teaching a robot. SOLUTION: This singular point avoiding method is for a tip of a robot arm not to pass through a singular point inherent to a robot, when carrying out direct teaching to the robot with plural joints. The tip of the robot arm is arranged to damp a component of velocity, which can not be realized at the singular point by a correction formula defined in advance, as it approaches to the singular point. In the correction formula defined in advance, a correction function to linearly make the component of velocity closer to zero, as the tip of the arm approaches closer to the singular point and to make it zero in the neighborhood of the singular point, is used. The correction function is a function having an index variable to indicate a distance from the singular point as its variable.

Title: Data transmission system
Inventor: TOYONAGA KENJI
Filed: 1985-03-01
Abstract: PURPOSE:To attain data transmission with priority from a terminal device whose transmission is stopped due to collision by providing a collision priority bit before a head address of a packet data deciding the priority of transmission. CONSTITUTION:Assuming addresses of terminal devices A, B, C, D as 0001, 0010, 0011, 0100, respectively. Suppose that the terminal devices A, D start transmission at the same time, a collision priority bit 1 is added to the head of a packet data sent to a bus line 1 from the terminal devices A, D by an address control means 5 and the result is sent. The state of the line 1 is fetched in a comparison means 3, where it is compared. The 1st and 2nd bits sent from the terminal devices A, D are both 1, 0 and they are coincident, but the 3rd bit of the terminal device A is 0, while that of the terminal device D is 1, and since the state 0 of the line 1 has priority, the means 3 gives a command to a transmission switching means 4 that the terminal device D stops the succeeding transmission. The means 4 stops the transmission of the terminal device D and the means 5 changes the collision priority bit of the terminal device D from 1 to 0. Thus, even when the terminal devices B, D are collided together, the terminal device D has priority.

Title: Floating decimal-point multiplier
Inventor: NAKANO HIROSHI
IPC: G06F7/38
Filed: 1990-02-22
Abstract: PURPOSE:To perform a rounding processing at a high speed by providing a means to each mantissa part of a multiplicand and a multiplier detecting the bit length having continuous 0 from the lowest-order together with an adding means for bit length having two continuous 0, and a bit length comparing means. CONSTITUTION:The additions 10 and 11 of reading bits and the detections 12 and 13 of bit length having continuous 0 from the lowest-order bit of a multiplicand and a multiplier respectively are carried out to the mantissa part which sets and outputs the multiplicand and the multiplier to the reading registers 3 and 4 from a floating point register 2. A multiplier 14 obtains the product of a mantissa part to set it to an intermediate product register 16 and then sets the bit length having continuous 0 to a register 17 via an adder 15. A comparator 18 estimates the OR of all bits lower than the rounding bit of the product as 1 when the sum of the bit lengths having 0 continuous from each lowest-order bit of the multiplicand and the multiplier is equal to the bit length having 0 continuous from the lowest-order bit of the product and at the same time smaller than the bit length lower in order than the rounding bit of the product. Otherwise the comparator 18 predicts the OR as 0. Thus the rounding processing speed is increased and the predicted OR is written into the register 2. Then the multiplication of floating decimal-points is ended.

Filed: 1997-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a landing measuring apparatus by which precise landing measurement can quickly and easily be carried out and landing adjustment in a manufacture line of television picture tubes is made easy. SOLUTION: When a magnetic field in-Y direction is generated in the periphery of a position to which the electron beam is radiated, the electron beam 14 radiated to a phosphor screen is deflected in-X direction while receiving Lorentz force and the radiation position of the electron beam is slightly shifted in the-X direction. In the case that the extent of the shift becomes high, the electroluminescence intensity of respective phosphor dots is lowered. The electric current to be applied to the coil for generating a magnetic field is changed step by step at prescribed intervals and the electroluminescence intensity obtained in every step is displayed in a bar graph in which the intensity is displayed as the corresponding height of the bar arranged in parallel to the vertical axis and while taking the graph into consideration, correction is carried out.  In the measurement mode, the extent of the landing shift from the peak position of the envelope line is computed.
