Patent EP-0884686-A2 (EP)
Inventor: MOU ALEX Z
IPC: H04N7/30
Filed: 1998-06-12
Abstract: A system and method of a forward and/or inverse discrete cosine transform in a
video system. In one embodiment, an array of DCT transform coefficients are converted
to a two dimensional array of spatial data. The array of DCT transform coefficients are
first operated upon by a pre-scale computation unit (implemented in either hardware or
software) which multiplies a set of predetermined pre-scale constants with the input
coefficients. The pre-scale constants multiplied by the input DCT coefficient matrix form
a symmetric pre-scale array. Upon pre-scaling using the symmetric pre-scale factor array,
an intermediary array is composed by performing intermediary calculations upon each
column vector of the pre-scaled array. The output of this intermediary calculation is
composed to form an intermediary array. Subsequently, a set of calculations are
performed row-wise upon each row vector of the intermediary array to thereby form the
output array of spatial data. In one implementation, the array of pre-scale coefficients
(i.e., the symetric pre-scale factor array) may be represented as the result of a matrix
multiplication MxUxM, where the array U consists of a set of coefficients all equal to 1,
and wherein the array M is an array of coefficients wherein the equal row-column
diagonal of coefficients include a set of pre-scale constants and all other coefficients in
the array are equal to 0. The pre-scale constants includes a set of constants expressed by
the cos(π/16), where n = 1, 2, 3 and 4. In another embodiment, the calculations are
reversed to perform a forward discrete cosine transform operation.

Abstract: A MOS-controllable power semiconductor trench device has a gate in the form of a
trench which extends through a region of p type silicon into an n type region of low
conductivity. A discontinous buried p layer below the bottom of the trench forms part
of a thyristor which in operation is triggered into conduction by conduction of a PIN
diode which is produced when an accumulation layer is formed in the n type region
adjacent to the trench under the action of an on-state gate signal. The device has a high
on-state conductivity and is protected against high voltage breakdown in its off-state by
the presence of the buried layer. An off-state gate signal causes removal of the
accumulation layer and conduction of the PIN diode and the thyristor ceases in safe,
reliable and rapid manner.

Abstract: In a tape drive (800), a host interface (810) receives from a host computer host data to be compressed
and stored to tape. The host interface (810) and also receives commands to create appendable points
in the resulting compressed data stream. A data formatter (820) formats the received host data by
encoding the data as codewords to form the compressed data stream, and co-operates with the host
interface (810) by inserting into the compressed data stream special flush codewords at the requested
appendable points. The formatter is also provided with the ability to insert flush codewords at
positions determined by the host interface (810) itself. The codeword that follows a flush codeword is
located at a pre-determined position relative to and after the flush codeword. Thus, appendable points
are locatable by their respective flush codewords in the compressed data stream.

Abstract: L'invention concerne un système hyperfréquence d'accès radio point à multipoint robuste et économique en fréquences. Ce système associe l'utilisation de deux bandes de fréquences uniquement à une alternance des polarisations. Une antenne de station de base qui alimente des secteurs adjacents à partir d'un site commun de la station de base, fonctionne avec des canaux différents de deux ensembles de canaux. En outre, les secteurs de sites adjacents d'une station de base (p.ex. dans des cellules adjacentes), ces secteurs étant alignés sur les secteurs du premier site de la station de base, utilisent soit un ensemble différent de canaux, soit une polarisation de différenciation. Ces deux ensembles de canaux peuvent être deux ensembles de fréquences (p.ex. AMRF).

Abstract: The invention relates to a transport system for conveying products during the production process, especially integrated semiconductor products, to facilities inside a building, where they are submitted to factory processing. The invention is characterized in that the transport system and the machining facilities are separated by a floor and that the supply process from the transport system to the machining center is made through opening in said floor. Such a system is advantageously built separately from the machining center, resulting in a significant increase of the supply pace. It enables any place in the plane of the system to be reached and to be accessed any time in case of failure. It also provides with the possibility to significantly reduce the complexity of the driving software.

Abstract: An automatic stop machine for a screw striking machine
includes a driver bit, an air pressure cylinder having a piston,
and an air motor driving the piston and rotationally driving the
driver bit. The automatic stop machine comprises an open/close
valve, a contact arm, and an air passage. The open/close valve
is disposed in an air supply passage to the air motor. The contact
arm freely slidable along a nose portion of the screw striking
machine, projects from the leading end of the nose portion, and
stops the air motor by closing the open/close valve when the
contact arm is pushed into a main body of the screw striking machine
and is moved upwardly as the screw is screwed. The air passage

surface of the piston in the piston when the piston reaches the
vicinity of bottom dead point. Pressure of the pressurized air
supplied through the air passage and upward movement of the contact
arm cooperatively cause the open/close valve to close when the
piston reaches the vicinity of bottom dead point.
