摘要:
A rotary actuator is disclosed which changes the angular position of the rotary valve which is used to determine the attenuation presented by a shock absorber. The rotary actuator is disposed within a cylindrical piston rod of the shock absorber, and comprises a power transmission mechanism for driving the rotary valve for rotation between a first and a second position within a given range, a d.c. motor for driving the mechanism, a first stop mechanism for selectively stopping the rotation of the motor at a third position which is situated centrally within the given range, and a solenoid assembly for making the first stop mechanism operative. These components are disposed within the cylindrical piston rod in the sequence named from below to above. The power transmission mechanism includes a second stop mechanism which prevents the rotary valve from rotating outside a first and a second location which determine the given range.

A vehicle height control device stops the operation of vehicle height adjustment if the vehicle height at a wheel can not be increased to a target value during a height increasing operation within a predetermined time period. Automatic restoration of vehicle height adjustment occurs after a predetermined period if the vehicle height has increased to a height greater than a threshold value. However, if such a detection is not made, vehicle height adjustment is locked up.

To more precisely output signals of optical recording media, a semiconductor laser element is mounted in a concave portion on the surface of a semiconductor substrate so that the optical axis of signal detecting light emitted from the semiconductor laser element is substantially parallel to the surface of the semiconductor substrate, and the light emitted from the semiconductor laser element is reflected at the side surface of the concave portion that is opposed to the signal detecting light emitting side of the semiconductor laser element in a direction substantially perpendicular to the surface of the semiconductor substrate. A light receiving portion for signal detection is provided in an area outside the concave portion on the surface of the semiconductor substrate where the semiconductor laser element is mounted. When the signal detecting light emitting side of the semiconductor laser element is the front side of the semiconductor laser element, a first light intercepting region is provided in areas posterior to, obliquely posterior to and at the left and right sides of the semiconductor laser element on the bottom surface of the concave portion, and a second light intercepting region is provided on, of the side surfaces of the concave portion, at least the side surface between the semiconductor laser element and the light receiving portion.
摘要:
An image processing apparatus can display a tomographic image of an object in a three-dimensional region and a three-dimensional or stereoscopic image, such as a three-dimensional surface image of the object or a three-dimensional transparent image thereof, simultaneously on a screen. A sectional plane from which the tomographic image is produced is freely designated on the three-dimensional image displayed on the screen. The sectional plane can be indicated on the displayed three-dimensional image by a cursor line. Further, a data processing range along the ultrasound beam direction can be determined on the displayed tomographic image, in which the three-dimensional image is produced from the echo data obtained from the data processing range. Such a data processing range can also be indicated on the displayed tomographic image by means of cursor lines.

摘要:
A brake fluid pressure control device controls brake fluid pressures through control of fluid pressure control valves operated in accordance with control signals from, for example, a computer. Signal lines for supplying control signals to control circuits controlling coils of linear valve devices for some wheels (e.g., front-left and rear-right wheels) are connected to a brake ECU by a connector, and signal lines for supplying control signals to the control circuits controlling coils of linear valve devices for other wheels (e.g., front-right and rear-left wheels) are connected to the brake ECU by a different connector. Thus, even if one of the connectors starts operating abnormally, it is possible to supply control signals via the signal lines connected by the other connector and control linear valve devices for some of the wheels (e.g., a pair of diagonally located wheels).
