IPC: H04N5/335
Filed: 2010-03-18
Abstract: PROBLEM TO BE SOLVED: To obtain an imaged picture signal having high S/N by shortening an electron multiplication drive time.SOLUTION: The signal charges corresponding to the amount of received light are read in a charge transfer path. A potential well 3, which is deeper than a potential well 1 on the charge transfer path where signal charges are accumulated, is formed on the charge transfer path via a potential barrier wall 4. The signal charge in the potential well 1 is dropped into the potential well 3 by making the potential barrier wall 4 disappear. At the same time, at least one continuous electron multiplying potential well 5 whose depth is identical to that of the potential well 3, is formed on the charge transfer path via a potential barrier wall 6, before the completion of driving of electron multiplication. The depth of the potential well 3 is restored to the depth of the potential well 1, after completion of driving of the electron multiplication, and then the potential barrier wall 6 is caused to continuously disappear so that the signal charge in the potential well 3 is dropped into the continuous electron multiplying potential well 5 for electron multiplication.

Title: Vehicle steering device
Inventor: TSUKASAKI YUICHIRO
IPC: B62D7/08
Filed: 2010-03-26
Abstract: PROBLEM TO BE SOLVED: To provide a vehicle steering device achieving a proper steering responsiveness in a simple configuration without deterioration of the driver's feeling.SOLUTION: Extendable portions 30l, 30r whose elastic properties corresponding to an axial force acting in a compressing direction and whose elastic properties corresponding to an axial force acting in a stretching direction are asymmetrical are disposed in a symmetric fashion at intermediate sections of tie rods 17l, 17r. Thus, an effective steering gear ratio with respect to leftward and rightward steering can be properly changed in accordance with a vehicle speed by using a simple configuration that does not use a complex mechanism having a motor. In this case, a steering gear ratio can be mainly changed for one of the wheels, while a linear lateral force corresponding to steering can be generated at the other wheel. Moreover, since the steering gear ratio can be changed mechanically without performing motor control, the occurrence of control delay can be prevented, thereby reliably preventing deterioration of the driver's feeling.
