Title: Retroreflective sign
Inventor: TAKAGI KAZUMASA
IPC: E01F9/00
Filed: 2006-02-25
Abstract: <P>PROBLEM TO BE SOLVED: To provide a retroreflective sign which enables the clear visual recognition of a pattern formed as a sign regardless of a daytime, early evening, or night.  <P>SOLUTION: The pattern 1 is formed of a prism retroreflector which enhances the visibility of the pattern 1 in the night. A substrate 2 encircling the pattern 1 along its entire periphery has a brightness of 30 or less in terms of an L value in the Lab system prescribed in the JIS standard Z8730, the L value representing a black tone or a tone close to it. As a result, reflected light reflected from the prism of the pattern 1 and the low brightness of the substrate 2 work in cooperation to generate a combined effect that high contrast is created even in the daytime or early evening to enable the clear visual recognition of the pattern 1 as the sign.  <P>COPYRIGHT: (C)2007,JPO&INPIT

Filed: 2006-03-06
Abstract: <P>PROBLEM TO BE SOLVED: To provide a magnetic detector and an electronic compass using it allowing to detect an external magnetic field accurately even in an environment in which there is a leaked magnetic field.  <P>SOLUTION: Positive and negative biased magnetic fields are applied to a sensor section 12 to determine first and second output voltages, and a first difference between the first output voltage and the second output voltage is calculated. Corrected biased magnetic fields, which are obtained by adding additional biased magnetic fields to the positive and negative biased magnetic field, respectively, are then applied to the sensor section 12 to determine first and second output voltages, and a second difference between the first output voltage and the second output voltage is calculated. The first difference and the second difference are compared to each other. When the first difference is larger than the second difference, the magnitude of the additional biased magnetic fields is increased, thereby minimizing the first difference, or reducing it to nearly zero.  <P>COPYRIGHT: (C)2007,JPO&INPIT

Title: Hill start controller for electric motor type four-wheel-drive-vehicle
Inventor: KAMATA TATSUYA
IPC: B60L50/16
Filed: 2006-03-07
Abstract: <P>PROBLEM TO BE SOLVED: To propose hill start control for early eliminating the roll back of an electric motor type four-wheel-drive-vehicle in hill start.  <P>SOLUTION: In hill start performed by releasing a brake pedal at t1, and pressing on a gas pedal at t2, the delay control of the increase in an engine output is performed so that the increase in the driving force of front wheels being engine driven wheels can be delayed against the pressing-on of the gas pedal as shown by Tf in the roll back when a speed VSP is generated in a backward direction. When the front wheel driving force (engine torque) is tried to increase as a dashed line Tfo according to the pressing-on of the gas pedal, the front wheel driving force is decreased as shown by a real line Tfo due to the driving slip of the front wheels, and the roll back is not eliminated until t4. The delay control of the engine output increase is performed to prevent the driving slip of the front wheels so that the front wheel driving force can be maintained so as to be large as shown by Tf, and that the roll back can be eliminated earlier at t3.  <P>COPYRIGHT: (C)2007,JPO&INPIT
