Patent EP-0180917-A3 (EP)
IPC: F01D17/14
Filed: 1985-10-30
Abstract: Herein disclosed in an exhaust gas turbine type super­
charger in which a casing of a turbine (6) is divided into two 
chambers (4, 5) along a flow direction of the exhaust gas to 
form an open scroll (4) and a closed scroll (5). The open scroll 
(4) feeds the turbine (6) with the exhaust gas over a full 
operational range of the engine (1). The closed scroll is 
opened to increase a flow rate of the exhaust gas to the 
turbine (6) when the supercharged pressure is high as in a 
high load/high speed operation of the engine (1). A port (7) is 
formed through a partitioning wall between the open scroll 
(4) and a downstream exhaust gas passage of the turbine 
and an opening/closing valve is interposed thereat to thereby 
bypass the exhaust gas to a downstream portion of the 
turbine (6) with the port (7) being opened, when the 
supercharged pressure becomes high.

Title: Improved ultrasonic image storage device and method
IPC: G06T5/40
Filed: 1983-01-10
Abstract: An ultrasonic imaging system for medical diagnostic 
purposes is provided. A first digital signal representative of a 
video input signal is provided. The first digital signal 
comprises a series of digital amplitude samples of the 
transverse component of the input signal. A second series of 
samples is provided from the first series. Each element of the 
second series is the arithmetic average of a group of 
elements of the first series. The second digital signal series is 
compressed to form a third digital signal series, the third 
digital signal series being stored. The compressing provides 
a third digital signal which is a non-linear function of the 
second digital signal such that the granularity of the stored 
signal is increased in regions of high diagnostic interest at 
the expense of decreased resolution in areas of low diagnos­
tic interest. When it is desired to display the stored digital 
image, the third digital signal is retrieved from the storage 
means (18) and expanded to provide the reconstituted 
second digitial signal which is thereafter directed to a video 
display (120).

Title: Felt and web run in yankee machines
IPC: D21F9/00
Filed: 1986-03-24
Abstract: Modern Yankee machines for thin paper qualities give the possibilities at present to approach machine speeds of 200 m/min with a specific weight of about 17 g/m<2>. The machine consists of a forming section (often called a twin wire former), a web transfer section (in which the formed sheet is transferred to the press felt), and a suction press roll over which the press felt with the web is turned so that the web presses against the warm Yankee cylinder. In order to increase line speed without encountering problems, the web is now formed between a felt (2) - or a press fabric - and a forming fabric (3). The forming unit, consisting of the felt and fabric is placed in such a position in relation to the press roll (8) that the web (10), when it is separated from the forming fabric (3), is transported by the felt (2) and can be led into a press nip against a Yankee cylinder (7) surface along a straight path.
Patent EP-0248141-A3 (EP)
IPC: D04H1/58
Filed: 1987-02-06
Abstract: A molded article, for example, a filter or a 
preform used in the manufacture of fiber-reinforced 
composites, is manufactured from an air laid batt from a 
single fiber type or a mixture of fibers. The batt is 
either resinated with a thermoplastic material or 
includes a thermoplastic binder fiber. The batt is 
formed into the desired shape of the molded article in a 
through-air mold (98) and heated sufficiently to set the 
thermoplastic material, so that the resulting article 
retains the desired shape. If the article is to be used 
as a fluid filter, it can he used either as it is removed 
from the mold if a filter of uniform density is desired, 
or the article can be further processed in a compression 
mold to densify portions of the article to thereby form, 
for example, a fluid impervious portion used as a 
gasket. If the article is to be used as a preform for a 
structural composite, it is then to be transferred to a 
resin injection mold (ll0).

Patent EP-0262865-A3 (EP)
Title: Improvements in the treatment of water to remove gas vacuolate cyanobacteria
IPC: C02F1/00
Filed: 1987-09-24
Abstract: The treatment of water to remove gas vacuolate cyanobacteria is effected by subjecting the water to a predetermined pressure by being pumped down a centrally located pipe (24) in a bore-hole (12), which is steel lined (13). This causes the gas vesicles in the cyanobacteria to collapse. The treated water is then stored in a settling tank (14) where the cyanobacteria sink to the bottom and can be removed along with any other sediment in the water. The method can be applied to decrease the amount of cyanobacteria with gas vesicles in a lake or other water impoundment.

Title: One button control for a simple running operation of a video tape recorder
IPC: G11B15/18
Filed: 1988-04-14
Abstract: 2.1 On known video magnetic tape recorders, the searching for certain positions on the tape is performed by means of a control button, which can be turned and adjusted axially between two positions and can be locked in each of the two axial positions. This known device requires a separate operating mode selection mechanism, demands considerable production effort and allows the direction of tape transport to be changed only by turning the control button back through its neutral position. The novel one-button control is intended to avoid these disadvantages. 2.2 Pressing the rotary button (1), irrespective of its angular position, causes closing of a switch (9), the output signal of which is fed to a microcomputer (8). Each time the rotary button (1) is pressed, the said microcomputer switches off the tape transporting motor (12). Each time after the rotary button (1) has been pressed, a return spring (11) returns it axially into its initial position. 2.3 Searching for certain positions on a tape on video magnetic tape recorders. <IMAGE>

Abstract: A bump electrode structure of a semiconductor 
device comprises an electrode pad (13) formed of an alu­
minum alloy, an insulating oxide layer (14) covering 
only the peripheral edge portion of the electrode pad 
(13), an under-bump layer (15) formed of an alloy of 
titanium and tungsten, and a bump electrode (16) formed 
of gold. The titanium-tungsten alloy functions both as 
a barrier metal and as a bonding metal. The bump 
electrode (16) rises substantially straight from the 
bonding surface of the under-bump layer (15), and its 
top portion has an area only substantially equal to that 
of the electrode pad (13). Fine V-shaped grooves (17) 
are formed on the top surface of the bump electrode (16) 
by anisotropic etching. Thus, the semiconductor device 
with fine electrode pad pitches is provided with a high-­
reliability bump electrode structure which ensures suf­
ficient bonding strength between internal and external 
electrodes.
