Patent EP-0352602-A3 (EP)
Title: Position-providing device
IPC: G01D5/34
Filed: 1989-07-18
Abstract: An optical position transmitter comprises a movable code element (36). A light beam (44) is directed onto the code element. The coding of the code element (36) generates in the reflected light beam (44) sub-light beams having different optical path differences. This may be effected by stepped surface portions on the surface of the code element (36). The optical path differences are greater than the coherency length of the light of the light source (62). The reflected light beam is directed through a beam splitter (42) onto an interferometer for detection of the optical path differences. Interferences between sub-light beams are permitted by well-defined quick changes in the interferometer with determined path differences. Position signals can be obtained from the thus obtained "interference peaks".

Filed: 1989-10-12
Abstract: A surgical operation device comprising an 
ultrasonic piezoelectric transducer (34) for generating 
ultrasonic vibrations, an oscillation feedback type 
oscillator (1) for supplying high-frequency power to the 
ultrasonic transducer, a vibration transmitter (62) 
connected to the ultrasonic transducer for transmitting

Title: Method of operating pulsed droplet deposition apparatus
IPC: B41J2/045
Filed: 1989-11-15
Abstract: A method of operating a pulsed droplet deposition 
apparatus for ejecting a liquid droplet from a nozzle supplied by 
a liquid retaining chamber comprises applying a first pulse (37) 
to the liquid in the chamber of sufficient energy to effect 
ejection of a droplet from the nozzle and thereafter applying a 
second pulse (39) to the liquid in the chamber to ensure that the 
meniscus (41) of the body of liquid to which the droplet is 
attached is convex in the direction of motion of the droplet at 
the time of detachment of the droplet. The energy content of the 
second pulse is insufficient of itself to effect droplet 
ejection. When employed in a multi-channel array printhead, the 
pulses applied to channels of the array selected for printing are 
produced e.g. by deflecting side walls of the selected channels 
or by applying heating pulses to liquid in the selected channels.

Title: Method and printing system for producing multiple part documents
Inventor: DOANE IVAN G
IPC: B41F17/02
Filed: 1993-08-17
Abstract: Multiple part documents in which each part has common 
non-variable information and variable information are 
produced at high speed with a minimum amount of equipment. 
Utilizing either sequential press technology or large 
diameter plates, the multiple parts of the document are 
sequentially printed on a single web with the non-variable 
information. The variable information is sequentially 
printed on the same web in a procedure distinct from the 
printing (at 15) of the non-variable information, typically 
utilizing a single ion deposition printer (12, 13) for each 
face of the web. The parts are separated and intelligently 
gathered (at 16) and then the parts are sealed together (at 
18) to form a document, along one edge, by applying glue, or 
pressure seal adhesive. After sealing the documents may be 
rotated (at 21) and delivered to a carrier web (at 22). 
Alternatively, an outer wrapper or envelope (at 24), variably 
imaged by another ion deposition print engine (at 27), may be 
provided around the multiple part documents after sealing.

Patent EP-0782186-A3 (EP)
Inventor: BRONNER GARY B
IPC: H01L21/334
Filed: 1996-12-13
Abstract: A buried plate particularly suitable for
formation of a common plate of a plurality of
trench capacitors, such as are employed in dynamic
random access memories, is formed by implantation
of impurities in one or more regions of a wafer or
semiconductor layer, epitaxially growing a layer
of semiconductor material over the implanted
regions and diffusing the implanted impurities
into the wafer or semiconductor layer and into the
epitaxial layer. Diffusion from such a source
avoids process complexity compared with provision
of diffusion sources within capacitor trenches and
further provides an impurity concentration profile
which varies with depth within the resulting body
of semiconductor material, resulting in a
well-defined boundary of the buried plate and an
isolation region both above and below the buried
plate. The structure allows biasing of the buried
plate as desired, such as for reducing electrical
stress on the capacitor dielectric to allow
reduction in thickness thereof and reduction of
area required for the trench capacitor.

Patent EP-0786795-A3 (EP)
Inventor: KOHDA YUZO
IPC: H01L21/205
Filed: 1997-01-13
Abstract: A deposition apparatus of the present invention
is arranged so that a surface area of a radio-frequency
power applying cathode electrode (1002) disposed in a glow
discharge space, in a space in contact with discharge
is greater than a surface area of the whole of a ground
electrode (1004) (anode electrode) including a beltlike member (1000)
in the discharge space. 
     This structure can maintain the potential
(self-bias) of the cathode electrode disposed in the
glow discharge space automatically at a positive
potential with respect to the ground (anode) electrode
including the beltlike member. 
     As a result, the bias is applied in the
direction of irradiation of ions with positive charge
to a deposit film on the beltlike member, so that the
ions existing in the plasma discharge are accelerated
more efficiently toward the beltlike member, thereby
effectively giving energy to the surface of deposit
film by ion bombardment. Accordingly, since the
structural relaxation of film is promoted even at
relatively high deposition rates, a microcrystal
semiconductor film can be formed at the relatively high
deposition rates with good efficiency, with high
uniformity, and with good reproducibility.
