Filed: 2002-05-08
Abstract: <P>PROBLEM TO BE SOLVED: To provide a color conversion apparatus capable of retaining, in an image after conversion, a black-and-white printer of an image prior to the conversion.  <P>SOLUTION: For a lock-up table, in which a color value B1 is assigned corresponding to a color value B2 in device link processing, the color value B1 represented by only an achromatic control signal is assigned corresponding to the color value B2 represented by another achromatic control signal only. Accordingly, on converting the color value B1 to the color value B2 by referring to this look-up table, when the color value B1 indicates a control signal (0, 0, 0, K) using an achromatic color material only, namely the black-and-white printer, the color value B2 of a color pixel, after the conversion, is also converted to the control signal (0, 0, 0, K), using only the achromatic color material. Accordingly, a part of an image, represented by the black-and-white printer in the image produced on a printer A1, is also retained as black-and-white printer in the image produced on a printer A2. Thus, the black-and- white printer of the image, before the conversion can be retained in the image, after the conversion.  <P>COPYRIGHT: (C)2004,JPO

Filed: 2002-05-27
Abstract: <P>PROBLEM TO BE SOLVED: To provide a steering system improving stability of vehicle movement.  <P>SOLUTION: According to the steering system 20, a grip condition between a grounding surface contacted by steering wheels and the steering wheels is estimated through grip estimation processing 30a processed by a AFS(Adoptive Front Lighting System)_ECU 30, and a VGRS (Variable Gear Ratio System) target angle is set by a grip vs. gear ratio map 30b based on the estimated grip condition so that a steering gear ration is increased as a grip limit gets close. This allows estimation of the grip condition changing with magnitude of road surface μ, and for instance when the steering wheels approach their grip limit, the steering gear ratio can be increased to larger setting even during low speed travelling. In travelling on a low μ road surface or the like, a phenomenon that the steering wheels are largely turned with a small steering angle is prevented from occurring, and the stability of vehicle movement can be improved.  <P>COPYRIGHT: (C)2004,JPO

Title: Low-power mram memory array
Inventor: BHATTACHARYYA MANOJ
IPC: G11C11/15
Filed: 2002-05-29
Abstract: PROBLEM TO BE SOLVED: To reduce the current required for a word line and a bit line in an MRAM memory array. SOLUTION: An MRAM memory array (100) is provided with nonlinear word lines (110) and linear bit lines (120). The word lines (110) cross the bit lines (120) at memory cell locations (130) and are coextensive with the bit lines (120) at crossing points. When the current is passed through the word and bit lines (110 and 120), magnetic fields, generated by the word line (110) and the bit line (120) at a coextensive portion, are substantially aligned. The magnitude of the resultant magnetic field is greater than in conventional, orthogonally oriented fields. By the increase of the magnetic fields generated by the word line (110) and the bit line (120), smaller word current and bit current can be utilized and the size of the memory array (100) is reduced.  The memory array (100) can generate a transverse magnetic field, by using memory cells (150) having a magnetic layer (162). the transverse magnetic field is oriented orthogonal to the magnetic field generated by the word and bit lines (110 and 120), and increases the reproducibility of switching of the memory cell (150). The transverse magnetic field also reduces the current required for switching the memory cell (150).
