Patent EP-0358506-A3 (EP)
Title: Three-dimensional cell and tissue culture system
IPC: A61K35/12
Filed: 1989-09-07
Abstract: The present invention relates to a three-dimensional 
cell culture system which be used to culture a variety 
of different cells and tissues  in vitro  for prolonged 
periods of time. In accordance with the invention, cells 
derived from a desired tissue are inoculated and grown on a 
pre-established stromal support matrix. The stromal support 
matrix comprises stromal cells, such as fibroblasts actively 
growing on a three-dimensional matrix. Stromal cells may 
also include other cells found in loose connective tissue 
such as endothelial cells, macrophages/monocytes, 
adipocytes, pericytes, reticular cells found in bone marrow 
stroma, etc. The stromal matrix provides the support, 
growth factors, and regulatory factors necessary to sustain 
long-term active proliferation of cells in culture. When 
grown in this three-dimensional system, the proliferating 
cells mature and segregate properly to form components of 
adult tissues analogous to counterparts found  in vivo .

Patent EP-0367712-A3 (EP)
Title: Clamping device
IPC: B25B27/14
Filed: 1989-11-02
Abstract: A clamping device is described for the fastening of sleeve-shaped members to plastic strings or the like, preferably to plastic strings for tennis, squash, badminton rackets or the like. The clamping device has two crossed legs which are connected to one another in an articulated manner and the longer rear parts of which serve as handles and the shorter front parts of which are formed as jaws designed to surround the sleeve-shaped member. Furthermore, the clamping device has at least one clamping nose which is designed to project in at least one jaw. In this connection, the clamping nose is formed so as to taper transversely to the pivoting plane of the legs. As a result of this, an optimally uniform distribution of the clamping force on the sleeve- shaped member is achieved, in such a manner that the clamping force which is exerted by the pressed-in region of the sleeve-shaped member after the clamping process - seen from the point of entry of the string into the sleeve-shaped member - gradually increases. <IMAGE>

Patent EP-0379024-A3 (EP)
IPC: H01L21/265
Filed: 1990-01-08
Abstract: In a method of manufacturing a semiconductor device 
of polycide gate structure, a polysilicon layer (4) is 
formed on the gate insulation film (3). The polysilicon 
layer and the gate insulation film are selectively 
removed to form an opening (11) which reaches the semi­
conductor substrate (1) in the polysilicon layer and the 
gate insulation film. After this, a silicide film (6) 
is formed directly on the polysilicon layer and an 
exposed part of the semiconductor substrate and then 
ion-implantation is effected to form source and drain 
regions. According to the manufacturing method, since 
the silicide film is formed in direct contact with the 
semiconductor substrate, charges caused by the ion-­
implantation can be easily discharged into the semicon­
ductor substrate. Therefore, no  a te charge will occur. 
Further, the gate oxide film is prevented from being 
brought into contact with the masking photoresist layer 
(5) by the presence of the polysilicon layer. There­
fore, damage of the surface of the gate oxide film due 
to the direct contact with the photoresist layer will 
not occur and unwanted material may be prevented from 
being injected from the photoresist layer into the gate 
oxide film.

Title: A method and apparatus for remotely and portably measuring a gas of interest
IPC: G01J3/26
Filed: 1990-04-26
Abstract: A remote gas measuring apparatus and method utilizes the optical absorption line characteristics to determine an amount of gas of interest as may exist in an area under study. The remote gas measuring apparatus includes a source of electromagnetic radiation (12) that can be projected toward the area in question and a light collecting arrangement (14). The light signal received is coupled to a fast light switch modulator (10) which modulates the light signal to a first frequency. A second modulating arrangement (40) modulates the light signal to a second frequency and includes a birefringent etalon device (42) having a periodic spacing equal to the periodicity of the absorption lines of the gas of interest. The second modulating means is further effective such that, when an electric field (48) is applied thereto the transmission spectra associated with the light signal is shifted between spectra which coincide with the absorption lines and spectra which fall between the absorption lines. The light signal from the etalon device is then conditioned and input to a detector configuration (56) which distinguishes between the light signal at the first frequency and the light signal at the second frequency in order to determine at least a quantity of the gas of interest.
