摘要:
A camera system which controls the driving of a focus lens through overlap control with a high degree of accuracy, is disclosed. The camera system comprises a lens apparatus with an image-taking optical system and a camera on which the lens apparatus is mountable. The camera system comprises a focus detection unit detecting a focusing state of the image-taking optical system, a driving unit driving the focus lens unit, and a controller controlling the driving speed of the focus lens unit and controls the focus detection unit to perform a focus detection operation at least once while the focus lens unit is moved. The controller sets the driving speed of the focus lens unit at the time of at least a final focus detection operation while it is moved toward an in-focus position, to a speed decelerated from the driving speed before the final focus detection operation.

摘要:
The present invention discloses a camera system comprising: a first focus detection unit, which detects the focusing condition of an image-taking optical system; a second focus detection unit, which detects the focusing condition of the image-taking optical system at a higher precision than the first focus detection unit; and a control circuit, which controls a stepping motor for driving a focus lens. The control circuit performs closed loop control for driving the stepping motor based on the output of a rotation detector, which detects the rotation phase of the stepping motor, when controlling the stepping motor using the information based on the output of the first focus detection unit, and performs open control for driving the stepping motor a predetermined number of steps at a time, when controlling the stepping motor using the information based on the output of the second focus detection unit. The autofocus process is thereby made high in speed and high in precision at the same time.

In lane keeping assistance system and method for an automotive vehicle, a control current (Iout) to be outputted to a motor during an automatic steering mode is detected, a filter is provided for the detected control current to pass only signal components of the detected control current whose frequencies are lower than a predetermined cut-off frequency value (fstr, fstr_low, fstr_mid, fstr_hi) to derive a filtered control current (Iout_lpf), a determination of whether a manual steering intervention to the automatic steering occurs is made according to a magnitude of the filtered control current, and the control current outputted to the motor is reduced toward zero when the manual steering intervention is determined to occur according to a result of determination that the magnitude of the filtered control current (Iout_lpf) is in excess of a predetermined threshold current value (Iout_lpf_th).
摘要:
A method of manufacturing a dielectric ceramic composition comprising at least a main component of BaTiO3, a second subcomponent as represented by (Ba, Ca)xSiO2+x (where, x=0.8 to 1.2), and other subcomponents. The main component and at least part of the subcomponents except the second subcomponent are mixed to prepare a pre-calcination powder and the pre-calcination powder is calcined to prepare a calcined powder. The second subcomponent is at least mixed in the calcined powder to obtain a dielectric ceramic composition having a ratio of each subcomponent to the main component of BaTiO3 of a predetermined molar ratio. It is therefore possible to obtain an electronic device containing a dielectric layer such as a multi-layer ceramic capacitor able to satisfy both of the capacity-temperature characteristics of the X7R characteristic (EIA standard) and the B characteristic (EIAJ standard), even when the dielectric layer is a superthin one of not more than 4 &mgr;m and having a small change in the capacity under a DC electric field along with time and further having a long accelerated lifetime of the insulation resistance and a small drop in capacity under a DC bias.

A vibration sensor is disposed at an evaluation point on the vehicle floor proximate the driver's seat. This sensor, in combination with one disposed on a electrically controllable engine mount, is used to determine the magnitude and orientation of a vector of vibration which reaches the evaluation point and which combines with other vibrational vectors in a manner which results in the generation of vibration at the evaluation point. A mount control signal is controlled in a manner which modifies the vibration vector and attenuates the vibration at the evaluation point.

A fluid circulating system includes a thermal differential engine having a pair of expansion-contraction vessels each containing an expansion component expansible with heat for discharging fluid to a delivery line when heated and drawing fluid from a return line when cooled. Heated water is supplied alternatively to the pair of vessels to circulate the fluid through the delivery and return lines. The pair of expansion-contraction vessels are identical in volume and other characteristics and have multiple ports connected to anti-convectional valves and change-over valve.

A wafer test method of a power switch wherein a main IGBT and a current detecting IGBT that detects a current value of the main IGBT are integrally formed on the same semiconductor substrate is such that there is provided resistance means that causes an emitter current of the current detecting IGBT to flow through an emitter terminal of the main IGBT, the main IGBT and current detecting IGBT are energized simultaneously, thereby applying a constant current to a common collector terminal of the main IGBT and current detecting IGBT, and a current ratio (main current/detected current) between a main current of the main IGBT and a detected current of the current detecting IGBT is calculated from the current flowing through the current detecting IGBT, obtained from the voltage across the resistance means, and the constant current.
