A system and method for automatically steering a vehicle along an intended path is provided. The system is architecturally partitioned. The partitioned design allows each of the system elements to be designed and maintained independently while allowing variation and flexibility in system configuration. An embodiment of the system elements may comprise a local navigation guidance unit, an external positioning system, a steering controller, and an installation and service computer. Additional elements of an embodiment of the system may comprise a steering position sensor, and at least one steering actuator. The system allows the operator to enter an intended target path and certain vehicle parameters. The local navigation guidance unit receives positional data from an external positioning system, preferably DGPS, indicative of a navigational path traversed by the vehicle. The guidance unit compares the positional data with the intended target path to obtain guidance error and transmits the guidance error to the steering controller. The system allows for determination of the current steering angle and generation of a steering angle adjustment based upon the intended target, the navigational path traversed by the vehicle, the vehicle parameters, the steering angle and the guidance error. The steering angle adjustment is used to actuate a steering mechanism to smoothly guide the vehicle along the intended target path.

A reciprocatory dry shaver has a shaving head carrying an outer cutter, and an inner cutter. An actuator is mounted in the shaving head for driving the inner cutter. The actuator includes an oscillator which carries a joint for driving connection to the inner cutter. Resilient coupling links are provided to support the oscillator to the shaving head in order to allow the oscillator to reciprocate relative to the shaving head. The resilient coupling link has its upper end coupled to the oscillator and has its lower end which is farther away from the inner cutter than the oscillator and is anchored to the shaving head. Thus, the oscillator is supported as being floated or lifted with respect to the shaving head, thereby being allowed to travel along a path which is somewhat arcuate in coincidence with the arc of the outer cutter.

A linear motion guide unit is disclosed in which there is provided a retainer band making it possible to easily fit a roller chain with rollers traveling through a recirculation circuit into a load way of the recirculation circuit, thereby making sure of smooth recirculation of the roller chain.

An object is to allow smooth guidance of the linear motion of an output member even when lateral moment acts on the output member, and to make it possible to stably transmit torque of a rotary shaft to respective planetary rollers without applying a preload to the planetary rollers by negative gaps between the rollers and the radially outer surface of the rotary shaft and between the rollers and the radially inner surface of an outer race member. The axial movement of a carrier (6) supporting the planetary rollers (7) is restricted, and the outer race member (5) is axially slidably fitted in the radially inner surface of a cylindrical portion (1a) of a housing (1) and is rotationally fixedly coupled to an object to be driven by means of keys (25), whereby the outer race member (5) serves as a linearly driven output member. The planetary rollers (7) have their radially inner surfaces rotatably supported on respective support pins (6c) of the carrier (6), and are radially inwardly biased by radial compression ring springs (21) wound around the support pins (6c) so as to envelop the support pins. The planetary rollers (7) are thus pressed against the radially outer surface of the rotary shaft (4).

A shaving foil for a dry shaver has a plurality of perforation arranged in an array. The shaving foil is formed in its skin contact surface with a plurality of recesses which define a thin section of reduced thickness at the recesses, while leaving thick sections at the remainder of the foil. Each perforation is configured to have its circumference defined partly by the thin section and partly by the thick section. Both of the thin and thick sections can come into contact with a user's skin for smoothly guiding hairs into the perforations to make close shaving without irritating the skin, while the shaving foil is moved across the skin. Especially, the thin sections act to cut the hairs shorter than the thick section, as wall as to raise flattened hairs into the perforations for successfully cutting the flattened hairs.
