Patent EP-0391041-A3 (EP)
IPC: B01D46/12
Filed: 1990-02-13
Abstract: The filter of the present invention continually 
provides the passenger compartment of a vehicle with a 
supply of purified air, even in the most severe 
environmental conditions. The filter comprises an inlet 
surface (12), an outlet surface (14), walls (30) which define a plurality 
of passages which extend from the inlet surface (12) to the 
outlet surface (14), and a filtration means for removing the 
impurities from the fluid. The filter preferably can be 
subdivided into a plurality of layers (20), including an inlet 
layer (12), an intermediate layer (22), an outlet layer (14). Each layer 
includes a plurality of cells, the cells having walls with 
a generally curvilinear shape. A plurality of the passages 
are preferably in fluid communication with a plurality of 
other passages. Surface filtration is used to remove the 
impurities from the fluid flowing through the passages. 
The impurities are retained within the filtration means 
which are disposed on the walls, as the fluid flows through 
the passages essentially unrestricted even when the 
removing means is saturated with impurities.

Title: Device for retaining wire-like optical wave-guide
IPC: G02B6/38
Filed: 1990-04-12
Abstract: A device for retaining a wire-like optical 
wave-guide, which is for use in an optical connector or 
the like, includes: a cylindrical plug (2) made of an 
elastic material for gripping the outer peripheral 
surface of a wire-like optical wave-guide (6), at least one 
end portion of the plug, having a predetermined length, 
being divided into a plurality of portions (10) in its 
circumferential direction, the cylindrical plug having 
an expanded form in which a distance from an axis of the 
plug to each of the divided portions (9) gradually increases 
toward the one end of the plug; and a tightening member (3) 
for pressing the vicinity of said free end of said 
cylindrical plug, which is in a state where the wire-like 
optical wave-guide is passed through the plug along 
the axis of the plug so as to allow the wire-like 
optical wave-guide to be retained by the cylindrical 
plug, in a direction substantially perpendicular to the 
axis of the plug from the outside of the plug and for 
deforming the divided portions and thereby causing a 
retaining force to be applied to the optical fiber in a 
proximal end of the divided portions, which is separated 
from the pressing portion (5).

Title: Solid image pickup apparatus for eliminating smear
IPC: H04N5/3722
Filed: 1990-05-14
Abstract: Solid image pickup elements are used in televi­
sion cameras, for example. A solid image pickup ele­
ment is capable of receiving light and generating a 
picture signal corresponding to the light. For this 
purpose, the solid image pickup element has a picture 
area formed of photoelectric converters arranged in a 
two-dimensional matrix and generates information 
charges corresponding to light incident on the picture 
area. The information charges obtained at the picture 
area are transferred to and stored in the store area, 
vertical column by vertical column. At that time, the 
charges more than the number of the vertical 
photoelectric converters of the picture area are 
transferred to the store area. The transfer in the 
absence of the corresponding photoelectric converters 
is thereby performed so that the smear charges are 
stored in the store area. With this information of 
the smear charges being stored, the smear charges are 
eliminated from the information charges.

Patent EP-0381485-A3 (EP)
Title: Improvements in apparatus for particle determination in liquid metals
IPC: G01N15/10
Filed: 1990-02-01
Abstract: The invention relates to apparatus 
for on-line particle determination in 
molten metals, wherein a sample of the molten metal is 
drawn by a vacuum through a calibrated passage (22) in 
the side-wall of a heat-resistant tube (16) while a 
current is established through the passage between two 
electrodes (12,14) on either side thereof. The 
passage of non-conducting particles through the 
orifice produces pulses whose magnitude and rate 
indicate respectively their size and the number of 
particles per unit volume. The electrodes (12,14) 
and their leads (30,32) form an interference-receiving 
antenna so that the wanted test signal, whose 
signal/noise ratio is inherently low, is subject to 
interference from neighbouring sources, such as 
motors, fluorescent lamps and particularly induction 
furnaces. The invention provides for the production 
of a cancellation signal to reduce the unwanted 
interference component in the test signal by means of 
a cancellation antenna sufficiently close to the 
detector electrodes to receive substantially the same 
signal, the antenna either feeding the cancellation 
signal to a differential amplifier also fed with the 
wanted signal, or being connected in series with the 
interference antenna. The cancellation antenna can 
comprise a loop mounted on the head that supports the 
two electrodes.
