Title: Evaluating method for picture quality
Inventor: SAIGO KAZUO
IPC: H04N1/00
Filed: 1993-02-08
Abstract: PURPOSE:To assure output of the evaluation value well corresponding to the subjective evaluation by extracting both pattern and random errors based on the degree of picture quality evaluation in accordance with function of a visual system. CONSTITUTION:The difference signal between an original image and a deteriorated image is converted into a second order derivative signal by a Laplacean-Gaussian filter 104. A control signal generating circuit 105 acquires a detection signal which decides whether the second order differentiation signal is included or not in a prescribed range of value near zero and excluding zero. Then the detection signal is smoothed and then binarized by the prescribed threshold value so as to acquire a control signal which divides the second order differentiation signal into a pattern error signal and a random error signal. An evaluation arithmetic circuit 106 calculates the evaluation value of the pattern error and an evaluation arithmetic circuit 107 calculates the valuation value of the random error respectively. Then a weighted sum arithmetic circuit 108 multiplies both evaluation value by each prescribed weighting coefficient and secures the sum of both multiplied values for calculation of the picture quality evaluation value. Thus the output is assured for the evaluation value well corresponding to the subjective value.

Title: Dc motor
Inventor: LANDER DANIEL
IPC: H02P7/28
Filed: 1998-01-30
Abstract: PROBLEM TO BE SOLVED: To provide a DC motor which realizes a DC motor control system which accuracy and at a low cost. SOLUTION: The number of armature windings (166 to 172) through which current flows is set to be smaller by one compared with the number of slots (156 to 164) formed to a rotating a commutator 154. By forming such a structure, the number of the armature windings, through which armature current flows changes with the rotation of the armature 148. As a result, the armature current fluctuates sequentially in the order of a maximum value A, median values B, C, a minimum value D, median values E, F, G, a minimum value H, median values I, J, and the maximum value K during a half turn of the motor in a constant DC voltage. The three conditions can be discriminated, therefore not only the relative position but also the absolute position of a shaft can be determined, thus enabling to utilize application to a highly accurate feedback control.

Abstract: PURPOSE:To permit the forming of a vessel inexpensively and accurately with a simple facility by a method wherein a hydraulic pressure difference is generated between the inside and the outside of the vessel while the vessel is formed by distributed loads, loaded by the pressure difference. CONSTITUTION:An evacuating pump 9 is driven and the opening degree of a valve 8 is regulated while monitoring an internal pressure by a pressure meter 7 to discharge air in a vessel 1 and evacuate the inside of the vessel to a predetermined pressure. Then, an external force F, generated by a pressure difference between an atmospheric pressure and the evacuated internal pressure, is applied on the whole surface of the outer wall of the vessel 1 since the atmospheric pressure is applied on the outer surface of the vessel 1. Then, the outer wall surface of the vessel 1 is pushed inwardly by the uniform distributed load whereby the wall surface, inflated outwardly, is corrected by the plastic deformation of the wall surface. According to this method, the forming of the vessel can be effected without providing the vessel 1 with hazardous local deformation or damage by local loading or point loading.
