Patent EP-0366903-A3 (EP)
Title: Filter spray head with ring-shaped filter segments
IPC: B01D29/46
Filed: 1989-09-06
Abstract: The filter spray head (1) is equipped with ring-shaped filter segments. These filter segments define both radial flow paths (28) and flow paths (26) which pass through the filter segments (18), which serve to guide filter liquid. These passages (26) through the filter segments (18) are constructed as passages (26) which narrow in the flow direction of the filtered water and are distributed evenly over the segment (18). The segments (18) exhibit stops which ensure that the passages (26) of two adjacent segments are not aligned. With such a filter spray head the risk of blockages is less than in the case of known spray heads. The former thus ensures a more regular operation and requires less frequent cleaning.

Title: Sealed charge storage structure
IPC: H01L27/115
Filed: 1989-08-24
Abstract: A memory cell in an EPROM device is totally sealed from 
ultraviolet light by a conductive cover (18) without openings therein 
for leads to the cell's drain, source and gate. Electrical 
communication with the source (18) is provided by direct contact with

IPC: F16L37/00
Filed: 1989-09-20
Abstract: A locking mechanism (10) for demountably 
securing a solenoid valve assembly (14) within a 
receptacle (13) in a wall (11) of a transmission 
housing (12) is disclosed. A retention means (35) is 
provided on a housing (22) of the solenoid valve 
assembly (14) which co-operatively interacts with 
various blocking faces (31,32,33) on a pillar means 
(25) present on the transmission housing (12) and 
located adjacent to the receptacle (13). A stop lug 
(45A), an engaging surface (43A) and a latching dog 
(55A) are each present on the retention means (35). 
First (31A), second (32A) and third (33A) blocking 
faces are present on the pillar means (25). 
Engagement of the stop lug (45A) with the first 
blocking face (31A) limits the angular range through 
which the solenoid valve assembly (14) may be rotated 
within the receptacle (13). When the stop lug (45A) 
engages the first blocking face (31A), the engaging 
surface (43A) is disposed in opposition to the second 
blocking face (32A) to preclude withdrawal of the 
solenoid valve assembly (14) from the receptacle (13). 
Engagement of the latching dog (55A) with the third 
blocking face (33A) normally precludes retro-rotation 
of the solenoid valve assembly (14) within the 
receptacle (13). Biasing means (50A) permits selective 
displacement of at least the latching dog (55A) out of 
engagement with the pillar means (25) to permit 
selective rotation, and retro-rotation, of the 
solenoid valve assembly (14) within the receptacle (13) 
to operate the locking mechanism (10).

Title: Orthogonal and inverse orthogonal transform apparatus
IPC: H04N7/26
Filed: 1989-10-25
Abstract: An orthogonal transform apparatus wherein in 
N-th order DCT or DST, the multiplier used for weighting 
N orthogonal coefficients Yi (i=0, ..., N-1) is one of, 
a combination of two or more of, or a multiple of one 
of, the following four sets:  
· COS (i/2N)  
· SIN (i/2N)  
· 1/COS (i/2N)  
· 1/SIN (i/2N)  
to thereby considerably reduce the number of multipli­
cations in both orthogonal and inverse orthogonal trans­
form as compared with the conventional. Since the 
number of multiplications required for calculating one 
orthogonal coefficient can be reduced, it is possible to 
reduce operation errors to be caused by multiplications. 
Further, it is possible to improve the operation preci­
sion of an orthogonal coefficient for lower frequency 
components which have an important role from the stand­
point of visual sense. Finally, by applying the ortho­
gonal transform apparatus to two dimensional orthogonal 
transform and two dimensionally weighting after obtain­
ing two dimensional orthogonal coefficients, it becomes 
possible to reduce the number of multiplications while 
performing a desired two dimensional weighting.

Title: Pressure regulator
IPC: G05D16/06
Filed: 1990-04-26
Abstract: A diaphragm actuated pressure regulator (10) is 
provided having a molded contoured diaphragm (18) capable of 
operation in the upper portion of the diaphragm's deflection 
stroke without experiencing material deformation and thereby 
preserving the precision of the diaphragm's response to 
pressure fluctuations. The pressure regulator (10) includes a 
curved lever arm (48) for transmitting the deflection of the 
diaphragm (18) to a displacement of a valve pad (56) which 
regulates the flow of gas from an inlet (62) through an 
orifice restriction (58) to an outlet (64). The lever fulcrum 
(50) is located in the throat area of the pressure regulator 
(10) and supported by a guide to provide a high lever ratio 
which enables a relatively small diaphragm (18) to generate 
a relatively high valve closing force. In a preferred 
embodiment of the invention the diaphragm (18) includes an 
O-ring shaped circumference (20) which is secured between 
the upper assembly (12) and the lower case (14) of the 
pressure regulator (10) thereby insuring an air tight seal 
without the need for an additional gasket or sealant material.

Title: Laser writing type liquid crystal light valve
IPC: B41J2/445
Filed: 1990-04-27
Abstract: A liquid crystal light valve cell has two optically 
different states switchable therebetween by DC voltage in 
response to laser beam. A ferroelectric liquid crystal 
layer (6) is sandwitched by a pair of front and rear alignment 
layers (5a-5b) to establish the two stable states of bistable state 
in the ferroelectric liquid crystal layer. The threshold 
voltage values of bistable state depend on temperature of 
the liquid crystal. A front electrode layer (2b) is disposed on 
the front alignment layer (5b). An optically reflecting layer (4) is 
disposed on the rear alignment layer (5a). A laser beam 
absorbing layer (3) is disposed on the reflecting layer (4) and 
absorbs thermal energy of laser beam (9) irradiated. A rear 
electrode layer (2a) is disposed on the laser beam absorbing 
layer (3) in cooperation with the front electrode layer (2b) to apply 
the DC voltage such that effective DC voltage is applied 
across the liquid crystal layer (6) to thereby effect the 
switching between the two stable states.

basic injection time (TJ) in dependence on second 
correction factors (KADAT) which are automatically 
modifiable by the system, which are fewer in number than 
the number of zones of sub-division of a working region of 
the engine (1) for the selection of these second 
correction factors (KADAT), these zones being addressable 
by address means in dependence on these information 
signals (20, 22) from the means (21) for detecting the 
speed of rotation of the engine and from the means (23)

Title: Electronic key locks
IPC: E05B9/08
Filed: 1990-04-05
Abstract: A lock which is adapted to transduce the code from a key by electronic means is constructed to resemble the form and functionality of a conventional mechanical cylinder lock. A main casing 1 houses the bolt 3, a rotatable thrower or cam for retracting the bolt, an electromechanical release mechanism which normally blocks rotation of the thrower, and a processor to control the release mechanism in response to the detected key code. The electronic reading means are located in association with the keyway 26 of a rotatable barrel 25 in a cylinder unit 19 manufactured as a separate unit from the main casing 1. The thrower and barrel 25 have respective cooperating mechanical couplings 36/37 and the main casing 1 and cylinder unit 19 have respective cooperating electrical connectors 34/33. The lock is therefore assembled by attaching the cylinder unit 19 to the outside of the main casing 1, thus establishing a rotary driving connection from the barrel 25 to the thrower and establishing an electrical connection from the key reader to the processor.

Each pile board inserting unit comprises a lifting bars for lifting stacked pile boards, a pile board inserting mechanism for pushing the top pile board into the sheet piling unit, a lower limit detecting switch for detecting the arrival of the lifting bars at a lowermost position, an automatic start switch which starts lifting bar raising operation only when the lower limit detecting switch is closed, warning means which provides an alarm upon the reduction of the number of pile boards on the lifting bars to a predetermined number, and stopping means for stopping the printing press after the duration of the alarm has exceeded a predetermined time. The pile board is inserted automatically into the sheet piling unit, and the operator is warned of the reduction of the pile board on the lifting bars by the alarm. <IMAGE>
