Title: Urethane resins
IPC: G11B5/702
Filed: 1988-10-08
Abstract: The urethane resin having hydrophilic polar groups, 
mercapto groups, shows excellent dispersibility of magnetic 
powder, when used as a binder for magnetic recording media. 
And, magnetic recording media prepared by using the binder 
are excellent in surface-smoothness and durability. 
Besides, the mercapto groups contained in the magnetic layer 
reacts with isocyanate groups in the polyisocyanate to form 
thiourethane bonds to leave no hydrophilic polar groups i.e. 
mercapto groups, thus being excellent in moisture- and heat-­
resistance as well.  
     The resin and the binding agent are advantageously 
used in the production of magnetic recording media, for ex­
ample, magnetic tape, magnetic disc, etc.

Title: Method of detecting an exposure field of an image in an image read-out process
IPC: G03B42/02
Filed: 1985-07-31
Abstract: In a method of adjusting read-out conditions 
for a radiation image stored on a stimulable phosphor sheet 
by limiting the radiation exposure field, digital image 
signals at respective positions on the stimulable phosphor 
sheet are detected on the basis of image information 
obtained by preliminary read-out. The digital image 
signals are subjected to a differentiation processing, 
and the radiation exposure field on the stimulable phosphor 
sheet is detected by use of the differentiated values obtained 
thereby. The read-out conditions in final read-out are 
adjusted on the basis of the image information obtained 
within the detected radiation exposure field by the 
preliminary read-out.

Title: Method and apparatus for driving a liquid crystal display panel
IPC: G09G3/36
Filed: 1989-12-19
Abstract: In a driver circuit of direct drive matrix type LCD 
panel, a quantity of ON-STATE cells (or OFF-STATE cells) 
displayed on the just previous scan electrode is counted 
and a quantity of ON-STATE cells (or OFF-STATE cells) to be 
displayed on a present scan electrode is also counted. A 
compensation voltage is generated according to a 
predetermined relation based on a difference of the two 
above-counted quantities, and is superposed onto drive 
voltages of unselected scan electrodes or of each of data 
electrodes, in a polarity that an undesirable spike voltage 
induced on unselected cell voltage is cancelled, in 
synchronization with selection of the present scan 
electrode. The compensation voltage may be generated 
according to a digital difference of the two quantities or 
to a change in an analog voltage representing the counted 
quantity. The above-described relation of the compen­
sation voltage versus the counted quantity difference may 
be proportional or may be given with a predetermined 
specific relation to meet the panel characteristics. The 
compensation voltage may be a flat voltage during the 
period for selecting the single scan electrode or may be of 
a spike waveform. Amplitude of this spike is determined by 
the above-described predetermined relation. An irregular 
panel brightness caused from spike voltages induced from 
data electrode voltage application is cancelled.
Patent EP-0343882-A3 (EP)
IPC: G06F9/44
Filed: 1989-05-19
Abstract: An application program (100) includes an action 
processor (101) which receives messages containing user 
syntactic actions. These actions are translated into 
semantic commands. The semantic commands are sent to a 
command processor (102) for execution.  
     The preferred embodiment of the computing system 
additionally includes an agent engine (108). The agent 
engine (108) may be used to perform many functions. It may 
be used to receive semantic commands from an application 
(100), and to record the semantic commands for later 
playback. It may be used to send semantic commands from a 
task language file (131) to an application program (100) for 
execution by the command processor (102). It may be used to 
intercept semantic commands sent from the action processor 
(101) to the command processor (102). After the command is 
intercepted, the agent engine (108) may be used to allow the 
semantic command to be executed, to prevent the semantic 
command from being executed.

Title: Recoating of stereolithographic layers
IPC: B29C67/00
Filed: 1989-09-26
Abstract: A stereolithography method and system for 
producing three-dimensional plastic objects by forming a 
plurality of thin layers of partially cured plastic 
material which are thin cross sections of the desired 
object. A layer of polymerizable resin is applied to a 
support surface and the excess is struck off, such as with 
a doctor blade (26), to form a smoothed layer. The smoothed 
layer is subjected to radiation in a predetermined pattern 
to form the cross-sectional layer into the desired shape. 
A plurality of layers are subsequently applied, leveled, 
then cured in the same manner to produce the desired 
three-dimensional object. Apparatus for measuring the 
level of the surface of a fluid is also provided. 
Variations in the level of fluid will be detected and may 
be used to drive a pump, diaphragm, or plunger (17) in order to 
maintain the level of the fluid.

Abstract: A light-emitting diode is mounted in the bottom of 
a cavity in a metal lead and the assembly is potted in a 
transparent plastic material. The walls of the cavity 
surround the sides of the light-emitting diode in 
sufficiently close proximity to effectively shield the

meters greater than the largest transverse dimension of 
the light-emitting diode. The front face of the light-­
emitting diode may be flush or beneath the face of the 
metal lead for minimizing stress. The cavity may be 
deep enough that the front face of the light-emitting 
diode is closer to the bottom of the cavity than to its 
open end. The front face may protrude beyond the open 
end of the cavity and be surrounded by a reflective 
surface. The edges of the front face of the light-­
emitting diode may be beveled for minimizing stress.
