Patent EP-0338488-A3 (EP)
Title: Multilayer structure and easily openable container and lid
IPC: B32B7/04
Filed: 1989-04-18
Abstract: A multilayer structure comprising (C) a substrate layer, (A) a surface layer of a thermoplastic resin, and (B) an intermediate layer of a thermoplastic resin sandwiched between the (C) substrate layer and the (A) surface layer, wherein the (B) intermediate layer contains 0 to 70 % by weight of a flake inorganic filler, the peeling strength between the (A) surface layer and the (B) intermediate layer is from 0.3 to 2.0 kg/15mm, and the peeling strength between the (B) intermediate layer and the (C) substrate layer is at least 1.2 times as large as the peeling strength between the (A) surface layer and the (B) intermediate layer. When a packaging container is produced by forming the multilayer structure into a container body and sealing the container body with a lid, easy openability and high sealing property will be ensured because the opening of the packaging container is not operated by using the delamination between the sealed portion but by using the easy delamination between the surface layer (A) and the intermediate layer (B). The use of the multilayer structure for production of packages is economically advantageous because the recovered scrap can be reused as the material for the substrate layer (C) without affecting the peelability of the surface layer (A).

Title: Fair arbitration scheme
IPC: G06F13/362
Filed: 1989-05-11
Abstract: A method and apparatus for selecting a particular node 
from a plurality of nodes connected to a common bus to 
allow the node to use the bus. The nodes have a pre­
determined priority. After initially enabling the nodes, 
the bus is monitored for a bus idle condition. It is 
then determined which of the nodes are enabled message 
nodes, which are enabled nodes that have a message to 
send on the bus. There is then arbitration between the 
enabled message nodes after the bus is in the bus idle 
condition for a first period of time, such that the 
enabled message node having the highest pre-determined 
priority among the enabled message nodes is disabled for 
arbitration purposes, and also at the same time selects 
a target and performs a transfer. This procedure is 
repeated until all the enabled message nodes have been 
disabled. Thereafter, all of the nodes on the bus are 
enabled when the bus is in the bus idle condition for a 
second period of time, which is longer than the first 
period of time.

insertion of non-defined text. A CRT is provided for 
displaying the received non-defined text in a line in which 
the cursor is positioned such that non-defined text 
characters are sequentially displayed rightwardly until the 
cursor moves to the right end of the line, and thereafter, 
the whole line is shifted leftwardly as the non-defined 
text characters are inserted from the left side of the 
cursor, and the characters arriving at the left end of the 
line disappears from the display means. Thereafter, all 
non-defined text revives on the CRT.

Title: Light valve projector for reproducing colour television signals
IPC: H04N9/31
Filed: 1989-11-21
Abstract: For the large-screen projection of colour television pictures, picture reproducing arrangements comprising three separate picture tubes are in most cases used which are followed by projection optics. The colour television picture is created on a projection screen by superimposing the three monochrome television pictures. Instead of picture tubes, light valves can also be used, particularly liquid- crystal light valves with illumination optics. To increase the luminance resolution of a light valve projector, a geometric offset arrangement, preferably by half a picture element width in the horizontal and vertical picture direction of the light valves is provided. New picture scanning values are calculated by a signal processing circuit arranged in the light valve projector, in such a manner that the position of the picture scanning values and the position of the picture elements of the picture scanning values and the position of the picture elements of the light valves correspond to one another. The light valve projector is particularly suitable for reproducing high-resolution colour television pictures. <IMAGE>

Title: Beverage preparation apparatus for vending machines
IPC: G07F13/06
Filed: 1990-06-25
Abstract: A hopper (31) communicates with a pressurisable 
cylinder (32) via a port (321) controlled by valve means. 
These comprise a cylindrical valve support (314) fixedly 
disposed in the hopper and extending to the port (321). 
tubular main valve shaft (332) extends to the inside of 
the cylinder through the valve support and has a main 
valve at its bottom end for opening and closing the port. 
An auxiliary valve shaft (334) extends through the main 
valve shaft with a certain clearance, and carries an 
auxiliary valve (333) for opening and closing the opening 
of the main valve shaft. The auxiliary shaft (334) is 
connected to a driving source at its head portion. A 
coil spring (335) urges the auxiliary valve shaft (334) 
upward to close the opening of the main valve shaft. 
Since the diameter of the auxiliary valve is less than 
that of the main valve, a relatively small size of a 
valve driving mechanism can be used for driving a 
beverage extracting apparatus. In addition, since the 
gap for exhausting high pressured air is small, the 
beverage extracting apparatus can prevent liquid mixture 
from being scattered in the inside of a vending machine.

Title: Method and apparatus for recording data transitions
IPC: G11B5/596
Filed: 1991-01-17
Abstract: A method and means is described for writing data on a recording medium, such as a disk or tape, containing servo samples in such manner that the number of servo samples is increased with a minimal increase in overhead (non-data) regions. The tracks on the medium are divided into a plurality of maxi sections, each of which contains all fields with servo and associated overhead information and also a data field. At least one micro servo section containing only a portion of said information is located within each data field. As each micro servo section passes by an associated recording head, writing and reading of data is temporarily interrupted, but resumed when the micro servo section moves beyond the head, in such manner as to require minimal resynchronisation of said data during reading. Using a phase continuous clock, data is written in both portions of a data field to either side of each micro servo section in one pass of the disk or tape relative to the head. The micro servo sections contain no timing reference address mark and require no data encoder/decoder flush or synchronisation byte to resume reading in the portion of the data field following each micro servo section. <IMAGE>
