Title: Controlling device of robot
Inventor: SETO TAKESHI
IPC: H02P6/08
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To provide a controlling device with a size and weight suited for receiving and sending information with a tactile sensation and to extend movable time, by equipping a magnetic field weakening control means for advancing a rotary magnetic field being generated by a stator at least by a specific angle in terms of an electrical angle due to a magnetic field caused by the magnet of a rotor. SOLUTION: Magnetic field weakening control is a control method for superposing a magnetic field that rotates at the same speed, opposes the pole of the permanent magnet of a rotor, and has an inverse polarity to a rotary magnetic field at the stator side for generating drive force. The synthetic generation magnetic field of the stator advances as compared with the magnetic field of the rotor at least by 90 deg..  When a load state-judging device 122 and a load direction-judging device 123 are in contact with a human or the like, they detect the loaded state according to current flowing to the motor of a motor drive circuit 113 and does not perform high-speed operation due to magnetic field weakening in a state where a movable part is directed toward the human, thus performing a high-speed operation with less occasions with the magnetic field weakening, reducing power consumption without limiting an expression operation required for the robot, and extending drive time.

Title: Image processor and recording medium
Inventor: MINAMINO KATSUMI
IPC: H04N1/393
Filed: 1998-11-27
Abstract: PROBLEM TO BE SOLVED: To magnify/reduce an image at higher speed with a simple method without deteriorating the image quality of the image. SOLUTION: An MPU 11 converts a denominator (n) of a magnification m/n into a value (k) being the power of '2' that is a minimum number and larger than number of pixels before conversion. The MPU 11 calculates a numerator (m) corresponding to the value (k) being the power of '2' on the basis of a percentage X[%] entered by the user. Thus, in the case of magnifying/ reducing the read image, a weight obtained on the basis of an addition/ subtraction of the calculated numerator (m) and denominator (n) that is the value (k) being the power of '2' is multiplied respectively by density of pixels adjacent to each other before the conversion and the products are summed, and the sum is divided by the denominator (n) that is the value (k) being the power of '2', that is, the sum is having only to be shifted to the left by k-bits.  Thus, the image can be magnified/reduced with a simple method at higher speed without deteriorating the image quality of the image.
