Title: Front and rear wheel steering apparatus
Inventor: MIMURO TETSUSHI
IPC: B62D7/15
Filed: 1987-07-22
Abstract: In a vehicle with front and rear wheel steering apparatus, when the front wheel steering angle detected by front wheel steering angle detecting means has reached one of a plurality of preset steering angles, control means steers the rear wheels in a stepped manner to steering angles corresponding to the plurality of preset steering angles. In Fig. 17, the solid line represents a locus of steering angles  theta r of the rear wheels when the front wheels ore steered from the neutral position to the right or left. For example, when the steering wheel is rotated through 180 DEG  to the right, the rear wheels are steered 2.5 degrees to the right in the high velocity mode and to the left in the low velocity mode. <IMAGE>

Title: Coating textile substrate
Inventor: HALLWORTH GERALD
IPC: D06N7/00
Filed: 1988-11-04
Abstract: A flexible laminate, such as backed tufted carpeting, is formed by bonding a fabric or polymeric backing layer to a pre-coated textile substrate. The substrate is pre-coated by advancing it past a perforated hollow transfer roller (3) containing an internal doctor member (4). Fluent settable coating material is fed to the substrate (1) so that it forms a well (6) between the substrate (1) and the doctor member (4) through the perforations of the roller (3). Coating material is deposited on the fabric (1) and is then set, for example by passing through an oven, to form the pre-coat. The spacing of the roller (3) and the substrate (1) and the pressure of the doctor member (4) on the perforated wall of the roller (3) are adjusted so that a pre-coate of desired thickness of density is obtained.

Title: Motor control apparatus compensating for backlash in motor selectively driving two mechanisms
Inventor: KOSHIISHI TAKAHO
IPC: G05B19/404
Filed: 1991-03-11
Abstract: A motor control apparatus operates a motor to selectively drive a first mechanism when the motor is rotated in a first direction and a second mechanism when the motor is rotated in a second direction. Each mechanism comprises a gear train driven by a undirectional clutch. They may drive the source and output sheet transports of a fax machine. The control apparatus generates pulses to rotate the motor through a predetermined angle in either the first direction or the second direction. Backlash in the gear trains which occurs on reversal of the motor direction is compensated by determining whether the motor is reversed, and adding drive pulses to rotate the motor through an additional angle corresponding to the backlash. On initial switching-on of a fax machine, the motor may be rotated in one direction so that its state in relation to backlash is determined. <IMAGE>

Title: Apparatus for extracting a text region in a document image
Inventor: SHIMOMURA SHOJI
IPC: H04N1/40
Filed: 1991-04-04
Abstract: A peripheral distribution of filled pixels in a document image is calculated by projecting the filled pixels in an X-axis or Y-axis direction. Minima (TX1, ..., TY1, ...) of the peripheral distribution are detected. The document image is divided into a plurality of primary image regions in accordance with a dividing lines (LV1, ..., LH1, ...) (Fig 5) intersecting the minima in the X-axis or Y-axis direction and the density of pixels in each region is assessed so that the document image can be classified into text regions (T), drawing regions (U) and picture regions (V) (Fig 7). Thus, the text regions can be extracted automatically from the document image without requiring a specific manual operation for extracting text regions by an operator. <IMAGE>

Title: Headlight for motor vehicles
Inventor: LOEWE RICHARD
IPC: F21V5/00
Filed: 1991-10-01
Abstract: The headlight exhibits a reflector (10), in front of which a diaphragm (13) is disposed, the edge (14) of which is imaged by means of an objective (16) to form the bright-dark boundary of the light distribution. The objective (16) exhibits, towards the reflector (10), a plane side (17) and, situated opposite, a convex side (18). The convex side (18) is subdivided into a central, round region (19) and a peripheral region (20) which surrounds the latter and which extends in a circular ring shape. The focal length of the central region (19) is shorter than that of the peripheral region (20), so that the two regions (19, 20) sharply image the edge (14) of the diaphragm (13) at different distances. As a result of this, for example at the location Q, where the edge (14) is sharply imaged by the peripheral region (20), an unsharp image of the edge (14) is additionally formed by the central region (19). <IMAGE>
