Title: Method and system for combining individual road transport and railway transport
IPC: B61D47/00
Filed: 1988-10-26
Abstract: A method for combining individual road transport and railway transport with a rapid transfer from the one mode of transport to the other is described. Articulated lorries are used as the transport units of the individual traffic, and only their load-carrying and transportation material-carrying semitrailer is transferred onto the low-level carriage of the railway transport in accordance with a transverse-rolling method known per se. The traction unit only serves as a power unit and supports the docking manoeuvre. After this, said unit is available again for other individual traffic transport duties. The movement energy is supplied by the traction unit to the semitrailer by means of removable current or air lines which are uncoupled after the docking manoeuvre. In order to secure the semitrailer in position on the low-level carriage, blocking devices are provided which can be actuated in self-service mode. Technical means which prevent the low-level carriage from tipping over during the load transfer are provided on the ramp and/or on the low-level carriages. These technical means consist for example of bolts which can be pushed forward on the low-level carriage and engage in corresponding profile strips on the ramp.

Patent EP-0326807-A3 (EP)
IPC: H01H13/12
Filed: 1989-01-07
Abstract: A slide (6), connected to the push-button (3, 4), is supported such that it can move axially in the housing (1). On the housing end facing away from the push-button (3, 4) there is a switching element (17) which contains one or more fixed contact pairs (33) and moving contact supports (27), each of which can be operated by a ram (18 to 20), associated therewith. The ram (18 to 20) is arranged such that it can move in the force path of the slide (6) with respect to the moving contact support (27) and is held in a first position under the influence of a spring (29) and can move into a second position counter to the influence of this spring. This is carried out in such a manner that, when the push-button (3, 4) is pushed, the slide (6) moves the ram (18 to 20) out of the first position into the second position, the ram thereby operating the moving contact support (27). In order to be able to operate the moving contact support (27) without play when the push-button is pressed, it is proposed that a pressure plate (11) be arranged in an overhung manner between the slide (6) and the ram or rams and that each ram (18 to 20) in each case exerts a restoring force on the pressure plate (11) by means of the associated spring (29). As a result of this restoring force, the pressure plate (11) is held in contact with the slide (6) at at least three contact points, the resultant of these restoring forces in the direction of movement of the slide (6) passing through the surface which is limited by the contact points.

Title: Data synchronisation
IPC: H04L7/04
Filed: 1989-06-20
Abstract: Data blocks are identified by associating with the blocks of an m 
block cycle respective bits from an m-bit chain code. The block 
number can then be decoded in a ROM from any n successive code bits 
where 2 n  - 1 is greater than or equal to m. To speed up the 
identification process a plurality s of successive code bits of the 
m-bit chain code are associated with each block. To uniquely 
identify the block number s is chosen to be mutually prime with 
respect to m, and the code bits are looked at only once every s code 
bits. The size of the decoding ROM does not need to be increased.

Title: Optically pumped lasers
IPC: H01S3/06
Filed: 1989-12-07
Abstract: Various examples of an optically pumped 
laser are described. In each example, a laser member 
formed from active laser material in located in an 
optical cavity and a source of pumping light is 
arranged so that pumping light passes into the laser 
member through a side surface. A deflecting means is 
provided which ensures that the pumping light makes 
an initial pass followed by at least one, and 
preferably at least two, further passes across the 
laser member. In the further passes, the pumping 
light has a substantial component long the optical 
axis. Consequently, a relatively long absoption path 
for the pumping light is achieved. In one example, 
the laser member is an Nd:YAG bar (20), the pumping 
light source is an array (23) of laser diodes, and 
the deflecting means takes the form of a series of 
facets (27) formed along a side of the bar (20). In 
another example, the defelcting means is a 
diffraction grating.

Title: Semiconductor device with self-aligned contact to buried subcollector
IPC: H01L21/8249
Filed: 1990-02-03
Abstract: A P- semiconductor material substrate (10) which has 
been ion-implanted with N-type dopants to form an N+ 
subcollector layer (12) is annealed in Argon to 
further remove implant damage and drive the dopant 
ions deeper into the P substrate (10). Next a lightly 
doped N- epitaxial layer (14) is grown on the N+ 
subcollector layer (12). This forms the blanket 
collector. A P- well region is formed by growing a pad 
oxide (15) of 10nm on the N- epi layer (14) and a 
200nm layer of nitride (17) is then deposited on top 
of the layer oxide (15). A photoresist etch mask is 
used to pattern the P- well region. A reactive ion 
etch is performed through the dielectric oxide (15) 
and nitride layers (17), through the epitaxial layer 
(14) and stopping in the subcollector layer (12). By 
the end of a typical bipolar process, the N+ subcol­
lector can be as wide as 1.5 microns. The depth of the 
P well is limited to the thickness of the N- epi (14). 
A layer (16, 18) of low temperature expitaxial material 
is grown over the structure using ultra-high vacuum/­
chemical vapor depositions such that the epitaxial 
layer extends above the surface of the epitaxial layer 
(14) and includes a P+ heavily doped layer (16) and a 
lightly P- doped surface layer (18). The P+ doped 
layer (16) may also include a more lightly doped layer 
(14) directly in contact with the epitaxial layer (14) 
to improve yield from defects occurring due to im­
mediately growing a P+ epitaxial layer (16) on top of 
 
 
a heavily doped N+ layer (12). The heavily doped P+ 
layer (16) provides the low resistance contact to the 
collector region and the lightly doped P- layer (18) 
is the collector region and its thickness is determined 
by the diffusion of the heavily doped layer during the 
entire process.
