Patent EP-0397530-A3 (EP)
Title: Alignment apparatus
IPC: G03F9/00
Filed: 1990-05-11
Abstract: A light source (1) emits light having two components 
which have slightly-different frequencies and which have 
different planes of polarization. The emitted light is 
separated into first, second, and third parts travelling 
along different paths respectively (7,10,11). First (17), second (18), 
and third (19) reference gratings diffract the first, second, and 
third light parts respectively. First, second, and third 
illumination optical systems selectively transmit the 
diffracted first, second, and third light parts 
respectively. First (30), second (31), and third (32) mark gratings 
having predetermined orientations are formed on a mask (28) and 
are illuminated with the first, second, and third light 
parts coming from the first, second, and third illumination 
systems respectively. Similarly, first, second, and third 
mark gratings are formed on a wafer (29) and are illuminated 
with the first, second, and third light parts coming from 
the first, second, and third illumination systems 
respectively. A first device (38) detects first optical beat 
signals of the diffracted lights coming from the first mark 
grating on the mask and the first mark grating on the wafer. 
Similar detection is made for the diffracted lights coming 
from the other mark gratings on the mask and the wafer.

Patent EP-0532986-A3 (EP)
Title: Electrically regenerable filter in candle form
IPC: F01N3/022
Filed: 1992-09-03
Abstract: 2.1 Known filters for separating out solids from the exhaust gases of an auto-igniting internal combustion engine, where the filter can be regenerated by burning off the deposited solids and the burning-off process can be initiated by electrical heating of the filter, have the disadvantage that at least under certain operating conditions, only incomplete burning-off of solids is achieved. This is due to the fact that the solids deposit on the filter upstream of the electrical heating in the flow direction and these layers deposited upstream in particular in the case of exhaust gas flowing through the filter during the regeneration process are insufficiently heated for initiating the burning-off process. 2.2 According to the invention, the filter is heterogeneously constructed, divided into a coarse-pore layer 1 and a fine-pore layer 2, the exhaust gas initially flowing through the coarse-pore layer 1 before the solids are separated out from the exhaust gas stream by the fine-pore layer 2. At the same time, the coarse-pore layer 1 is designed to be electrically conducting, so that during a regeneration process, complete burning-off of solids is ensured. <IMAGE>

Patent EP-0564200-A3 (EP)
IPC: G06F3/042
Filed: 1993-03-26
Abstract: Collaborative work on an interactive system is facilitated by accurately capturing and 
displaying information on an interactive system, wherein multiple persons may work together 
for supplying and receiving information with a single large area display. A large area electronic 
writing system is provided which employs a large area display screen (190), an image projection 
system (182,184,186,188), and an image receiving system including a light emitting pen (200). 
The display screen is designed with the imaging surface in front of the substrate, with a thin 
abrasion resistant layer protecting the imaging surface from the pen tip. The screen (190) is 
held together with dowel pins pressed through the layers, and is curved to provide pressure for 
holding the layers together and mechanical rigidity against flexure during writing. The 
imaging surface disperses light from both the projection system and the light pen. The image 
receiving system comprises a very large aperture lens (194) for gathering light energy from the 
light spot created by the light emitting pen (200). The amount of energy from the light spot 
which reaches the integrating detector (198) is more critical to accurate pen position sensing 
than the focus of the light spot, so that the aperture of the lens (194) is more important than its 
imaging quality. The light emitting pen (200) is modified to additionally disperse light at its tip.

Inventor: ALBRECHT ALAN R
IPC: H04L69/40
Filed: 1996-02-09
Abstract: A network system includes end nodes which are connected to a
plurality of cascaded hubs. Each hub is able to generate a network error
packet when a timeout is detected. More specifically, a first hub starts a
first timer upon the first hub acknowledging a grant to a first device
connected to a first port of the first hub. Upon expiration of the first timer
without the first hub beginning to receive a first network packet over the first
port, the first hub begins to send a first error packet to a second device
connected to the first hub. If the first hub begins to receive a second error
packet over the first port after expiration of the first timer and before the first
hub has completed sending the first error packet, the first hub appends the
second error packet to the first error packet. If the first hub does not begin to
receive any error packet over the first port before completely sending the first
error packet, the first hub marks the first port as failed.

Abstract: A high latent cooling control assembly
for a compression-expansion air conditioning
system employs a subcooler coil (44) disposed
in the leaving air side of the indoor air evaporator
coil (22). A liquid line branch (42) supplies
condensed liquid refrigerant from the condenser (16) to the
subcooler coil (44), and a flow restrictor (48),
which can be a TXV, drops the sub-cooled liquid
pressure before the refrigerant reaches
the expansion device (20) associated with the evaporator
coil (22). A bypass line (50) connects the
condenser (16) to the expansion device (20), and has a liquid line
solenoid valve (32) that is humidistat
actuated. When dehumidification is
called for, the solenoid is
closed and refrigerant flows through
the subcooler coil (44). When the humidistat is satisfied, the
solenoid opens and the refrigerant
path bypasses the subcooler coil (44). The high latent subcooler
assembly (40) can be field-installed or retrofitted
onto an existing air conditioner.
