Patent EP-0266882-A3 (EP)
IPC: G02F1/355
Filed: 1987-09-25
Abstract: This invention is concerned with materials for 
nonlinear optical devices for the conversion of optical 
energy at one frequency to optical energy at another 
frequency.  
     Laser techniques have been developed so that it 
is possible to obtain a limited number of fundamental 
frequencies of coherent laser light by utilizing solid, 
gas, and liquid media. However, in many applications, 
laser light having frequencies not among the fundamental 
frequencies obtainable is required, and in some cases laser 
light exhibiting a continuous spectrum over a certain range 
of frequencies is required.  
     Inorganic materials have been used extensively 
for nonlinear optical applications. However, they are only 
of limited use because of their bandwidth limitations.  
     The possibility of using organic materials in 
nonlinear optical devices has generated much interest 
recently because a large number of organic materials are 
available for investigation and because they do not have 
the bandwidth limitations of inorganic materials.  
     This invention provides devices comprising a 
laser source of coherent light radiation at a fixed 
fundamental frequency, a crystalline N,N′-substituted 
barbituric acid that crystallizes in a non-centrosymmetric 
configuration, means for directing the output radiation of 
the laser onto the N,N′-substituted barbituric acid, and 
output means for utilizing the second harmonic frequency.

Title: Apparatus for detecting distribution of electric surface potential
IPC: G01R29/14
Filed: 1989-05-09
Abstract: A voltage is electrostatically induced at a 
sensing device (ED) in correspondence with a surface potential 
of a measured object (O). In the case where the sensing device 
uses a field effect transistor (DF) in transferring detected 
information, there are some factors decreasing the accuracy 
of detection. Various new arrangements prevent such 
decreases in the accuracy of detection. In the case of the 
surface potential of the measured object corresponds to an 
optical image, new arrangements ensure accurate detection 
of the optical image. In some cases, color component 
signals are obtained on the basis of a detection signal.

Title: Method of inhibiting the spread of disease and infection in structures
IPC: F24F8/28
Filed: 1989-08-21
Abstract: A method of inhibiting the spread, transmission and 
incidence of disease, infection and asthma and rhinitis 
allergies, characteristic of hypersensitivity pneumonitis in 
structures employing forced or induced air ventilation, 
heating, humidification and air conditioning systems. 
Microorganisms contribute to the disease and aggravate the 
condition of allergies or initiate allergic response. In the 
method, the level of exposure of occupants of the structure 
to high levels of microorganisms is reduced by treating 
interior surfaces of the structure with an organosilicon 
quaternary ammonium compound. The threshold level of 
airborne microorganisms is lowered with the organosilicon 
quaternary ammonium compound in order to prevent 
reinfestation and the intrinsic antimicrobial activity of the 
treated surfaces is used to kill transient and resident 
microbes.

Patent EP-0367094-A3 (EP)
Title: Optical disk apparatus
IPC: G11B7/09
Filed: 1989-10-25
Abstract: An optical disk apparatus comprising a head (3) 
having an objective lens (6), a tracking controller 
(16), a CPU (23), and a counter (41). The CPU (23) 
determines a tracking error if the count of the counter 
(41) is greater than a predetermined value when the disk 
(1) is rotated 360°C after the counter (41) has been 
cleared during data-reproducing operation. Then, the 
CPU (23) outputs a tracking re-try signal to the tracking 
controller (16). In response to this signal, the con­
troller (16) locks the lens (6) at the center position 
within the head (3). Then, the frequency of vibration 
of the lens (6) decreases so much that servo tracking is 
no longer required. When the relative rate-of-change of 
tracking position between the head (3) and the disk (1) 
has decreased sufficiently, the CPU (23) determines that 
the head (3) is applying a laser beam onto the target 
track of the disk (1). Thus, every time a tracking 
error is made due to an external force (e.g., 
vibration), the servo tracking is automatically 
performed, and the apparatus is therefore reliable. The 
CPU (23) also outputs a tracking re-try signal if the 
head (3) is stopped upon completion of coarse accessing 
of an optical disk (1). In this case, too, the lens (6) 
is locked at the center position. Therefore, the 
vibration of the lens (6) can be suppressed within a 
short time after the completion of the coarse accessing. 
As soon as the relative rate-of-change of tracking 
position between the lens (3) and the disk (1) decreases 
sufficiently, the head (3) starts applying a laser beam 
onto the target track of the disk (1), thus tracking the 
optical disk (1). Hence, the optical head (3) can 
access the target track at high speed.

mother liquor; and    (c) recovering the second liquid from the remaining 
mother liquor.     
     Typically, the two liquid substances are 
tetrahydrofuran and toluene and the complexing agent is 
titanium tetrachloride. The precipitatable complex is 
TiCl₄·2C₄H₈O or TiCl₄·C₄H₈O. Preferably, a cooling step 
is included in the method to enhanc the removal of the 
precipitatable complex. Superfractionation of the remain­
ing liquor in distillation columns enables one to recover 
toluene, hexane, titanium tetrachloride and tetrahydrofu­
ran. An apparatus for carrying ou the method of recover­
ing solvents is also disclosed.

ing polymer dispersion and the aqueous dispersion 
containing a fluorine-containing polymer have excellent 
heat resistance and weather resistance inherent in 
fluororesins and are significantly improved in film 
formability, transparency and adhesion to substrate. 
Therefore, these aqueous dispersions can be used as a 
coating composition for various applications, a fiber-­
treating compound, a paper-processing compound or a 
floor-coating compound.
