Abstract: A vehicle location detecting method for detecting the 
location of a vehicle within a predetermined area, comprising 
the steps of: outputting distance data at every predetermined 
interval, the distance data being representative of the 
distance that a vehicle has travelled, outputting heading 
angle data at every predetermined interval, the heading angle 
data being representative of the heading angle change of 
vehicle travel, storing road map data representative of 
roadways, computing a present location data from the distance 
data and the heading angle data, and a limit error of the 
present location data which is determined by errors in the 
distance data, in the heading angle data and in the road map 
data, and registering locations on the roadways, which 
roadways are located within the limit error of the present 
location data, as estimate locations, computing correlation 
coefficients corresponding to the registered estimate 
locations, and selecting a correlation coefficient whose error 
is smallest with respect to the roadway from the computed 
correlation coefficients and outputting the registered

Abstract: The machine produces spools of dielectric films, 
metallised on one side or with metal films intercalated 
between them, around a support of non-circular section 2. 
The films pass around two fixed rollers 3a and 3b, 
supported for rotation by a structure 10, and a 
compensating roller 4, supported by the free end of a bar 5 
hinged to the structure 10. The bar 5 is acted on by a cam 
6, driven in rotation synchronously with the support 2, so 
that the compensating roller 4 is moved to compensate for 
the variations in speed of take up of the films 1 by the 
support 2 and thus to maintain a constant speed of take off 
of the films from feed spools situated prior to the fixed 
rollers 3a and 3b.

Abstract: A magnetic read/write head (14) is mounted on a 
carriage (28) having a semi-circular recess (40) 
therein. A threaded lead screw (20) is partially 
surrounded by the recess (40). A partial nut (44) having 
an arcuate front surface (50) with two male thread 
segments (52) thereon engages the lead screw (20). The 
partial nut (44) is supported on the carriage (28) so that 
rotation of the screw (20) causes movement of the carriage 
(28) relative to the screw (20), in a direction parallel 
to the longitudinal axis (58) of the screw (20). The 
partial nut (44) is biased into engagement with the screw 
(20) by a coil spring (64) which extends between the 
partial nut (44) and a cap (60) which is spaced from the 
rear surface (48) of the partial nut (44). The spring 
(64) applies a constant, predetermined force on the 
partial nut (44). The direction of the spring force is 
substantially parallel to the longitudinal axis (56) of 
the spring (64). Thus, the head (14) can be precisely 
positioned by the rotation of the lead screw (20). Also 
disclosed is a method of positioning the magnetic head 
(14).

Abstract: A cartridge for a printing ribbon 13 for a typewriter having a 
character-carrying disc 21 comprises a casing 12 and two oscillating 
arms 38 between the ends of which a run of the ribbon extends in a 
straight line on the outside of the casing between the disc 21 and 
the platen 23. The arms 38 oscillate from a rest position in which 
they make the typing point 24 visible, to three or more working 
positions in which they make it possible to print using one of three 
tracks of the ribbon. The two oscillating arms 38 are pivoted by 
means of pins 42 on seats 51 of fixed supports 52 of the casing 
12. Pivotally mounted at the free end of each arm 38 is a guide 
element 67, a stem 66 of the guide element being received in a sleeve 
63 of the arm 38. Each guide element is thus capable of modifying 
its angular position with repsect to the respective arm in response 
to the selection movement so that the ribbon 13 is always held in 
tension in a uniform manner, irrespective of the track selected.
Patent EP-0266870-A3 (EP)
IPC: H04Q11/00
Filed: 1987-09-02
Abstract: The present invention relates to a multiple-user communciation system 
wherein one carrier source (10) is shared by a cascade of users of the system. 
More particularly, the present communciation system uses a single carrier 
propagating along the system's transmission medium (11) onto which each user 
directly impresses the associated data or communciation signal destined for 
another user preferably using either subcarrier angle modulation (phase or 
frequency) or TDM techniques for intensity or angle modulation. In the present 
system using subcarrier angle modulation, each user can either transmit or 
receive at a fixedly assigned or selectively assigned subcarrier channel, which is 
different from the subcarrier channel assigned to each of the other users. 
Where TDM techniques are used, the communication signal from a user can be 
directly impressed on the single carrier using intensity or phase modulation. 
With such communication system, amplifiers (18) can be liberally used along the 
transmission medium with no inter-modulation distortion since the amplifiers 
see a constant envelope signal. The use of amplifiers solves the problem of 
excessive signal loss incurred when multiple users tap into or out of, for 
example, an optical fiber bus.

Title: Method for injection molding, apparatus therefor and moldings produced thereby
IPC: B29C45/17
Filed: 1988-11-10
Abstract: In a process for producing an injection molded product, a stream of plastic material is introduced into a mold space 11 at a first pressure. Gas is stored in a storage chamber 28 at a second pressure which is at least as high as the first pressure. The gas is introduced into the molten stream of plastic material immediately after the molten material has passed the position at which the gas is introduced thereby forming a gas cavity in the molten material. The gas exerts pressure on the surrounding plastic material to urge the material toward the surfaces of the mold space. As the feeding of the plastic material into the mold space continues, the injection of the gas is also continued. The supply of molten material is terminated when the surfaces of the mold space are completely covered by the molten material. A pressure is held within the gas cavity as the plastic material cools. Subsequently, the pressure is released to bring the gas cavity to ambient pressure. The the mold 9, 10 is opened to remove the hollow shaped article. An apparatus for producing an injection molded product is also disclosed.

Title: Method and apparatus for increasing image generation speed on raster displays
IPC: G06F3/037
Filed: 1989-09-29
Abstract: An image data generation circuit for a conventional 
raster display comprises a graphics systems processor 
and a standard video dynamic random access memory (VRAM) 
interconnected by an address translator circuit. The 
VRAM is connected to the raster display. The graphics 
system processor is preferably an off-the-shelf graphics 
system processor capable of drawing horizontal lines 
very quickly. This graphics system processor is 
configured to transpose raw data to achieve the same 
horizontal drawing speed while drawing in the vertical 
direction and feeds the resulting image data to the 
address translator circuit. The address translator 
circuit reconverts the image data for storage in the 
VRAM so that the image data can be accessed in a 
conventional manner to modulate the electron beam of the 
raster display. In one example, this results in an 
eight-fold increase in the update or refresh rate of the 
corresponding image on the raster display.
