Filed: 1989-06-29
Abstract: A ballast control apparatus for an electric 
discharge lamp (1) comprises a first series circuit 
including a first winding (5) of an Ac supply voltage 
transformer (4), a first winding (7) of a ballast 
transformer (8), a lamp current sensing resistor (11) 
and the lamp (1). A current sensing transformer (13)

transformer (4), the ballast transformer (8) and the 
current sensing transformer (13) are connected in a 
second series circuit. A signal voltage proportional 
to lamp power is derived by adding together the voltages 
included in the three series-connected second windings 
(9, 16, 14). A second signal voltage proportional to 
lamp voltage is derived across the series combination 
of the second windings (9, 16) of the ballast trans­
former (8) and the supply voltage transformer (4). 
The voltage induced in the second winding (14) of the 
current sensing transformer (13) is proportional to 
lamp current. A signal voltage indicative of the 
condition of the lamp load can be derived across the 
second winding (9) of the ballast transformer (8). 
These three signal voltages are used to control a DC/AC 
inverter (2) that energizes the lamp (1) via the supply 
voltage transformer (4).

Title: Coffee brewing system
IPC: A47J31/057
Filed: 1989-06-28
Abstract: A coffee brewing unit is disclosed which enables a brew 
cycle to be initiated automatically upon insertion of a 
coffee receiving vessel (40) into its coffee receiving 
position, but which prevents a brew cycle from 
proceeding if a number of required operating conditions 
are not implemented. If all operating conditions again 
become implemented after a brew cycle, once underway, is 
interrupted, the brew cycle continues on to completion. 
Visual signals indicate that a brew cycle is in progress 
and also when sufficient mineral deposits are present 
that cleaning of the unit is recommended. An insulated 
carafe (40) is used as the vessel to receive brewed 
coffee thereby eliminating the need for a warmer plate. 
The unit may be mounted under a cabinet to thereby 
maximize usable countertop space and a coffee basket 
(30) for the unit utilizes a dispensing valve (86) which 
is opened by the carafe (40) when inserted into position 
but which closed when the carafe (40) is withdrawn. 
Temperature sensitive switch (98) which is used in 
association with the hot water generator (62) for the 
unit has a manual reset switch which is actuated by a 
self-contained water reservoir (24) when moved into its 
operating position.

Patent EP-0365333-A3 (EP)
IPC: G11B7/24053
Filed: 1989-10-20
Abstract: An optical recording element according to the present 
invention comprising: (i) a transparent substrate (1) through which 
light passes; (ii) a transparent low-resistance layer (2) having a 
specific resistance so as to prevent the adhesion of dust to the 
surface of the element caused by a static charge, the layer being 
formed on the surface, on which a light beam is incident, of the 
transparent substrate; and (iii) an optical thin film (3) composed of 
at least one layer, formed on the other surface of the transparent 
substrate so as to transmit light beams used for recording, erasing 
and playback, and reflect lights which have wavelengths different from 
the wavelength of the above light beams and are within a specified 
visible region of the spectrum. With this arrangement, lights within a 
specified visible region of the spectrum are reflected so that the 
element appears to be colored according to the wavelengths of the 
reflected lights. Also, a problem often found in a conventional 
optical recording element having a transparent substrate of a resin 
material that the surface of the element is hardened by a light beam, 
can be solved. Even if a static charge is generated on the surface of 
such an element, the conductive transparent low-resistance substrate 
can eliminate the static charge outward whereby a  
 
static charge is less likely to be accumulated and the surface can be kept 
clean in order to improve the reliability.

to the electrodes (14,16). The filament (24) provides 
a sufficient electric field and an abundance of electrons 
dispersed throughout the discharge region to initiate 
an arc discharge when the electrodes (14,16) are ener­
gized. The filament is selected to produce an electric 
field in the discharge region prior to initiation of 
arc discharge of at least 20 volts per centimeter. After 
an arc discharge is initiated, the voltage between the 
electrodes (14,16) drops, and the filament (24) is part­
ially short-circuited by the arc discharge. The filament 
provides fast initial starting and fast hot restarting, 
while eliminating the requirement for high voltage start­
ing pulses.

Patent EP-0342107-A3 (EP)
IPC: G06F5/12
Filed: 1989-05-05
Abstract: An almost full flag for a FIFO includes first and 
second counters for determining the proximity of the Read 
and Write pointers in the FIFO. A compare circuit is 
provided for comparing the output of the counters to 
determine when the count values are separated by a 
predetermined value. When the separation is equal to the 
predetermined value, the output of the comparitor goes 
low. A half flag is set when a Write operation occurs 
and the difference value between the Read and Write 
pointers increases. The set operation is performed in 
response to the presence of the compare signal at a low 
logic state at the time that the Write operation occurs, 
thus eliminating any delays in generating a transition in 
the compare circuit. The flag is reset when the compare 
signal is at the low logic state. Blanking circuitry is 
provided for blanking the reset operation when a Read 
operation occurs and the output of the comparator makes 
a transition from the first logic state to the second 
logic state. The blanking operation occurs for a 
predetermined duration of time to allow the counter to 
settle before performing the reset operation.
