A drive mechanism and an imaging device according to the present invention each include: an ultrasonic linear actuator 4 provided with a rod 42 that moves reciprocally in response to expansion/contraction of a piezoelectric element 41 and a first group unit 2 serving as an example of a moving body that engages with the rod 42 with a prescribed frictional force. The moving body (first group unit 2) is provided with a holding member 24, a pressing member 30 or other member that engages with the rod 42 in such a way that fluctuation in the frictional force is suppressed, and drive performance is stabilized. As a consequence, the drive mechanism and the imaging device according to the present invention can suppress fluctuation in the frictional force (gripping force) of the moving body in the ultrasonic linear actuator 4, making it possible to stabilize drive performance.

In an image pickup device 1 and a method for manufacturing same according to the present invention, one end of a rod 42 in an ultrasonic linear actuator 4 is supported tiltably by a first supporting section (for example, a front frame 52), and after the position of the ultrasonic linear actuator 4 is adjusted in such a manner that an optical axis of a moving lens group (for example, a first unit 2) which engages with the rod 42 is perpendicular to an element surface of an image pickup element 7, a piezoelectric element 41 which is connected to another end of the rod 42 is fixed by adhesive to a second supporting section (for example, a rear frame 51) which is disposed in the vicinity of the piezoelectric element 41. The adjusting jig according to the present invention includes: a first jig which is used for the positional adjustment and abuts against a reference surface of the image pickup element 7; a second jig which abuts against a reference surface of a holding member which holds the moving lens group, the reference surface being perpendicular to the optical axis of the moving lens group; and an adhesive filling unit for ejecting adhesive. According to this composition, it is possible to improve the tilt accuracy of the moving lens group independently of the component accuracy, as well as being able to achieve height reduction.

A parking assist system includes an image obtaining means for obtaining an image of a view from a vehicle, a displaying means for displaying the image obtained by the image obtaining means in a monitor display provided in the vehicle, an inputting means for inputting a target parking position, at which the vehicle is parked, on the monitor display, a detecting means for detecting a relative relationship between the vehicle and the target parking position, and a judging means for judging whether or not the vehicle can be parked at the target parking position based upon the relative relationship detected by the detecting means.

The present process is a process for preparation of crystalline grains-oriented ceramics which comprises orienting grains of ceramics raw material powder to a definite direction by applying centrifugal force on the grains and then burning the resulting grains. These ceramics are expected to be utilized, for example, as .beta.- or .beta."-alumina solid electrolytes for use in sodium-sulfur cells and as magnetic anisotropic ferrite magnets for use in small-sized motors, speakers or the like.
摘要:
In a parking assist apparatus that assists with moving, by automatic steering, a vehicle from an arbitrary stopping position to a target parking position set by the driver, a setting portion (i.e., a parking assist ECU) sets both a path from the stopping position to the target parking position and a steering operation necessary to bring the vehicle along that path. When this path cannot be set with the steering angle in the stopping position set as the initial steering angle, and when the path can be set with another steering angle as the initial steering angle, an instruction portion (i.e., a monitor or a speaker) instructs the driver to turn the steering wheel to this other steering angle.

A travel support apparatus includes: a rear sensor that detects an obstacle behind a vehicle; and a rear contact prevention device that controls travel of the vehicle to prevent contact between the vehicle and the obstacle detected by the rear sensor as the vehicle backs up. The rear contact prevention device prevents contact between the vehicle and the obstacle detected by the rear sensor as the vehicle backs up, by performing first travel control to apply at least one of speed limitation and deceleration to the vehicle, without requiring an operation performed by a driver of the vehicle, and then performs second travel control to reduce an operation amount set in the first travel control.

A radar sensor detects a traveling state of a host vehicle. An inter-vehicle control ECU gives the amount of operation for the predetermined amount of control of the host vehicle so that the traveling state of the host vehicle detected by the radar sensor becomes a predetermined state. The amount of operation given by the inter-vehicle control ECU is reduced as a kind of restriction when the amount of operation given by the inter-vehicle control ECU becomes equal to or larger than a predetermined value. As a result, it is possible to reduce the dependence of the driver on the device.
摘要:
A running control apparatus for controlling a running state of a vehicle by adjusting acceleration and deceleration of the vehicle releases the running control in case of a predetermined steering operation or more while the vehicle is stopped during the running control. This prevents the vehicle from running in a direction not intended by a driver at the time of starting, and the driver can be prevented from feeling a sense of discomfort at that time. Preventing the vehicle from starting in the direction not intended by the driver can also improve the running safety. This can restrain the vehicle from running in a way not intended by the driver upon a steering operation while the vehicle is stopped.
