Title: Avoiding fine line disappearance in picture reduction processes
IPC: H04N1/393
Filed: 1989-03-17
Abstract: A process for reducing a picture,by determining 
monochrome data of converted picture pixels according to 
logical calculations based on monochrome data of 
original picture pixels by using divisional regions of a 
picture area according to a reduction rate,  
includes the steps of: successively 
receiving monochrome data of original picture pixels in 
the vicinity of a converted picture pixel; producing 
data of a line susceptible to disappearance, such data 
being necessary for detecting pixels along a line in the 
converted picture which could disappear from the 
converted picture due to picture conversion; discrimi­
nating regions in which the converted picture pixels are 
located; calculating monochrome data of a converted 
picture pixel based on the generated data of a line 
susceptible to disappearance, data of discrimination of 
regions in which the converted picture pixels are 
located, and monochrome data of the original picture 
pixels; and producing a signal indicating the monochrome 
data of the converted picture pixel according to the 
calculation of monochrome data of the converted picture 
pixel, thereby to avoid disappearance of fine lines in the 
course of the reduction process.

Patent EP-0372711-A3 (EP)
Title: Fail-safe optical transmission system
IPC: H04B10/02
Filed: 1989-11-02
Abstract: Diverse routing can be achieved by using two completely 
separate optical systems to send the same signal along diverse routes 
simultaneously; or, by splitting the optical fiber by means of a 
fused-fiber (3dB) splitter to send the same signal along two diverse 
routes. A 2x2 electro-mechanical optical switch can be used to select 
the appropriate optical fiber.  
     A 3dB splitter is more economical 
than two separate optical systems. However, the 3dB splitter 
introduces a loss factor which is excessive.  
     An optical modulator 
can be substituted for a beam splitter. The modulator, often 
comprising a lithium niobate switch, is used to impress a digital 
signal on a dc optical beam. The lithium niobate modulator has a cw 
optical input, an electrical control input representative of digital 
data, and normally two digital optical outputs. One output is 
generally used as the modulated line signal, and the other output, 
which is the complement of the modulated signal, is terminated in an 
index matching oil to prevent reflection.  
     Briefly, in this 
invention, the previously discarded digital optical output of the 
optical mode is not discarded. It is used as a signal source for the 
diverse route thereby avoiding the need for any further loss producing 
beam splitters. The advantages are significant. The laser is on 
continuously. Therefore, there is no chirp. The power (on average) is 
directed 50% of the time to one output and 50% of the time to the 
other output. Thus, there is no power loss as in the case when a 
splitter is used. Where appropriate, at the receiving end, 
complementation can be performed to retrieve the original bit pattern 
if the complement of the signal is being detected.

Patent EP-0551597-A3 (EP)
Inventor: WILLIAMS GREGORY E
IPC: H02K5/24
Filed: 1992-11-26
Abstract: A door operator for a reversibly operable door, such as a garage door, includes a frame and a carriage movably mounted on the frame and attached to a door for moving the door between open and closed positions. A flexible drive member, such as an endless chain, extends on the frame and is capable of moving the carriage. A drive train is on the frame connected for moving the flexible drive member. A motor housing is mounted on the frame within the motor housing and connected to the drive train. The motor has a shaft extending from the motor housing and engaging the drive train. A bearing assembly that includes metal thrust bearings is on the shaft adjacent to the motor. The metal thrust bearing assembly increases the performance of the electric motor, and thus provides a more powerful motor without changing to a larger motor or otherwise modifying the motor design. The motor is mounted on the frame so as to allow the shaft freely to move axially relative to the motor to permit the shaft to self-align. The rotor thus seeks its position of least resistance and maintains this position without manual adjustment, providing an improvement in motor performance. <IMAGE>

Inventor: TAKAHASHI YASUO
IPC: G06K19/07
Filed: 1995-03-17
Abstract: To receive a response signal from a radio card
(4B), a card reader (4A) transmits a carrier (not modulated)
to the radio card (4B). In the radio card (4B),
a phase modulator (51) phase-modulates the a sub-carrier
with a response signal, thereby generating a PSK signal,
and a phase modulator (50) phase-modulates the carrier
with the PSK signal, producing a PSK-PSK signal. The
PSK-PSK signal is supplied to an antenna (47) via a
signal-extracting device (48). The antenna (47) sends
the PSK-PSK signal toward the card reader (4A). In the
card reader (4A), a distributor (53) distributes the
PSK-PSK signal to a synchronous detector (54a) and an
orthogonal detector (54b). The detectors (54a, 54b)
performs synchronous detection by using carriers which
differ in phase by 90°. Low-pass filters (55a, 55b)
extract sub-carrier components from the outputs of the
detectors (54a, 54b). The sub-carrier components are
delayed and detected by delay detectors (56a, 56b) and
added together by an adder (57). The level of the
output of the adder (57) is determined by a data discriminator
(58), whereby the card reader (4A) obtains the
response signal transmitted from the radio card (4B).
