Patent EP-0368194-A3 (EP)
IPC: G11B11/105
Filed: 1989-11-06
Abstract: In a magneto-optical disk for recording, 
reproduction or erasing with a laser beam, which comprises 
a film of four-layer structure consisting of a first 
dielectric layer (2), a magneto-optical recording layer (3), a 
second dielectric layer (4) and a metallic layer (5), laid on a 
disk substrate (1) provided with guide tracks, temperature 
distribution of the magneto-optical recording layer (3) is 
controlled by controlling the thermal diffusivity of the 
metallic layer (5), and recording/reproduction/erasing 
repetition characteristics are improved thereby. In the 
disk of the present structure, the temperature is elevated 
in a broader area from the center of laser beam, and thus 
a thoroughly broad erasing domain width taking a track 
offset into account can be obtained and not recording 
domains remain after the erasing. The reproduced signal 
output is increased by 4 dB, as compared with that 
obtained by a disk of three-layer structure without any 
metallic layer, because the beam utilization efficiency is 
increased owing to both Kerr effect and Faraday effect. 
When the disk of the present structure is subjected to 
field modulation recording, tails of arrow-feather-shaped 
recording domains peculiar to the field modulation 
recording can be shortened and interbit interferences can 
be overcome, resulting in an increase in C/N (S/N) ratio 
and the high density recording can be made. By endowing a 
Kerr enhancement action to the second dielectric layer (4) and 
a protective action on the magneto-optical layer (3) 
 
 
to the first dielectric layer (2), only the reliability can be 
improved without lowering the C/N ratio. By improving the 
corrosion resistance of the magneto-optical recording 
layer, the first dielectric layer (2) can be omitted to the 
contrary, and a magneto-optical disk of simple structure 
can be obtained and used as memory for domestic applica­
tions or communication fields.

Title: Noise reduction circuits
IPC: H04N5/21
Filed: 1989-02-07
Abstract: A noise reduction circuit comprises a high-pass filter (34) for 
extracting a signal component containing noise from an input signal, a 
variable level limiter (35) for limiting the level of the signal 
component extracted by the filter (34) to produce a noise suppressing 
signal, and a level adjuster (44) for adjusting the level of the noise 
suppressing signal. A level detector (46) detects the level of the 
input signal, and a control signal generator (47) generates first and 
second control signals based on the detected output of the level 
detector (46), supplies the first control signal to the level limiter 
(35) so as to control the limit level thereof, and supplies the second 
control signal to the level adjuster (44) so as to control the gain 
thereof. In a signal subtracter (33), the noise suppressing signal 
from the level adjuster (44) is added with reversed polarity to the 
input signal to suppress the noise contained in the input signal and 
thereby produce a low-noise output signal.

Title: Leak detector
IPC: G01M3/16
Filed: 1989-05-16
Abstract: A leak detector for use particularly in domestic environments with clothes 
and dish washing machines is made up of a mat for locating beneath the 
machine likely to leak. The mat (11) comprises a laminar base having a 
surface of relatively low electrical conductivity on which is provided 
first and second arrays (12, 15) of conductors of relatively high electrical 
conductivity, the conductors of the first and second array being juxtaposed 
with, but spaced apart from, each other so as to leave short and normally 
non-conducting paths between juxtaposed conductors in the first array (12) 
and those in the second (15). A first junction (13) communicates with the 
first array (12) to enable a voltage to be applied to the conductors of the 
first array (12). A second junction (16) communicates with the second array 
(15) to enable a voltage to be applied to the conductors of the second array 
(15). An electrical change-of-state detector (19), including a triggering 
device (22), is coupled between the first and the second junctions (13, 16) 
so that in the event of a change of state caused by a conducting path being 
established between a conductor in the first array and one in the second 
array, such as by leakage from the machine onto the mat, the change of 
state detector (19) is caused to operate the triggering device (22).

Patent EP-0634801-A3 (EP)
Inventor: BERGEVIN BENOIT
IPC: H02S40/12
Filed: 1994-07-07
Abstract: This invention relates to a photovoltaic system comprising a
casing having mounted therein a plurality of solar cells. The casing
has a front and opposite thereto, a rear. The front of the casing is
provided with a light-transmitting panel for transmitting solar light
to the solar cells. The rear is a double wall. A first wall is in
contact with the back of the solar cells, and on its side away from
the solar cells is of a dark-opaque colour, solar-light absorbing surface.
The second wall is a light-transmitting enclosure of the dark-opaque
colour side of the first wall, but spaced therefrom so as to produce a
greenhouse effect. A method to remove snow, frost and ice over a
photovoltaic system involves maintaining the light-transmitting panel
at an angle with the horizontal, receiving reflected solar rays from
the surroundings of the photovoltaic systems through the light-transmitting
enclosure to the outer side being dark-opaque colour to
be absorbed by the outer side and converted into heat to be transmitted
to, and thereby to raise the temperature of the light-transmitting
panel.Simultaneously the light-transmitting enclosure creates
a greenhouse effect and thereby an additional temperature increment
to further raises the temperature of the light-transmitting panel to
melt or sublimate snow, frost and ice present thereon.
