Abstract: In order to protect a junction between mechanical parts
made from different metals from electrolytic corrosion,
there is interposed between the parts a protective shield
which is formed from sheet metal, generally steel, the
surface of which is treated to render it electrically
passive; more particularly, in the motor-vehicle field,
the connection between the flange of a wheel bearing and
the respective strut or between the flange and the end of
a shock absorber or of a disc brake may be the seat of
electrolytic corrosion; such corrosion is caused by
electrovoltaic potentials generated in the zone of
contact between different metals in the presence of
moisture; the protective shield may also cover the side
of the outer ring of the bearing and cooperate with the
seal as an additional labyrinthine sealing element.

Abstract: An information recording device is provided, whereby an
inexpensive stepping motor is used to drive a recording disk
for recording information, the disk being driven under open-loop
control by means of inexpensive digital circuit
technology, without employing rotor position detectors or a
speed detector, and the rotational accuracy of the recording
disk is raised to a level suitable for application, without
increasing cost, by constituting the aforementioned step
operation (having poor rotational accuracy) inherent in the
stepping motor such that certain relationships are formed
between the structural parameters of the information
recording device and the structural parameters of the motor.
In a stepping motor, electrical energy is supplied by
switching excitation at a timing synchronized to an input
clock, regardless of the load. When this electrical energy
is converted to mechanical energy, the moment of inertia of
the rotating portion is exploited to a maximum in order to
produce smooth rotation.

Abstract: The invention is concerned with case catches (figure 4) comprising a claw (40)
which can be driven by a crank mechanism through a finger plate (12) so as to
retract the claw towards the finger plate and draw two parts of the case
together. The mechanism includes an intermediate plate (22) which is journalled
for rotation within the thickness of the cover plate (10) and is trapped between
the parts which are arranged to turn with the finger plate (12,14,16,18,20) on
one side, and the face plate (24) on the other side. The assembly is held
together by the rivets (28,30) and freedom for rotation is maintained when the
riveting step is completed, despite the part 32 being of the same thickness of
the part (10) and hence liable to be trapped between the rotating assembly on
the one side and the plate (24) on the other side, by the provision of a swaged
annular rib (32).

Abstract: The invention relates to an optical integrated circuit
for bidirectional communications which is able to achieve
a downsizing and high integration with the production cost
thereof decreased. An optical waveguide circuit 20 is
formed on a substrate 25 and a photo diode (PD) 8 is
connected to the outgoing end 29 side thereof. The optical
waveguide circuit 20 has a circuit of an optical
wavelength division multiplexer which causes communication
signal light (λ1) inputted from a bidirectional light
input/output port 33 to be transmitted through a
communication light selective transmission filter 24 and
to be outputted from a communication light output port 34
and causes non-communication light (λ2) to be reflected by
the communication light selective transmission filter 24
and to outgo through a non-communication light output port
35. A piezoelectric element 15 is provided on the upper
part at the outgoing side 29 of the communication light
output port 34. When the communication signal light
passing through the optical waveguide circuit 20 is
inputted into the PD 8, the PD 8 is actuated in the
reception mode to receive communication signal light and
is not driven in the transmission mode to reflect
communication signal light toward the optical waveguide 
circuit 20 side by a high reflection coating film 30. The
reflection light is given polarization plane modulation by
the piezoelectric element 15, and the polarization plane
modulated light is transmitted from the bidirectional
light input/output port 33.

Abstract: Bands of predetectors (112, 116a, 116b, 116c, 118a, 118b, 118c, 120a, 120b, 120c) detect
the approach of lines of glyphs within an image being scanned. Linear lines or arrays (110) of glyph
detectors are sampled in accordance with the detected approach of lines of glyphs. Each detector
array (110) includes a plurality of analog glyph detectors which respond to the presence of glyphs with
a characteristic analog output. Preferably, the glyph detectors generate a corresponding analog output
of a first polarity or other characteristic in response to glyphs of a first orientation and an output of a
second polarity or characteristic in response to glyphs of a second orientation. The analog signals
which are characteristic of the detection of a glyph are converted into binary 1's and 0's in accordance
with the polarity or other characteristic of the signals. In this manner, glyphs are detected by analog
detectors and the information encoded in the glyphs is directly output as a binary signal without
computer analysis of the image.

Abstract: Circuits and methods for subdividing a decoder into functional blocks that
can be accessed separately. The decoder includes a decoder module having a
parser, a block decoder and a motion compensation engine, which can all be further
subdivided into functional blocks. The functional blocks can be bypassed in
decompressing frames where the blocks are not necessary, or when the compression
algorithm does not require the functional block, increasing the speed of the decoder.
The functional blocks can also be reused for decompression or compression based
on different standards, or for different operation in the decoder, such as
decompression and compression. The decoder can be coupled to a processor and
some of the functional block performed in the decoder's hardware and some are
performed in the processor. In one embodiment of the invention and the processor
determines which block are to be by-passed completely and which block are to be
performed in software based on the decompression protocol to which the
compressed frame is encoded to comply to, the capacity and speed of the processor,
and the available memory. In another embodiment multiplexers can be added to
the decoder to connect functional blocks so they can be by-passed or reused based
on preprogramming of the multiplexers based on the decompression protocol to
which the compressed frame is encoded to comply to, the capacity and speed of the
processor, and the available memory.

Filed: 1998-05-08
Abstract: A high operational speed clock extraction circuit,
which can be manufactured to be compact at low cost. In
order to reduce the operational speed of a phase
comparator, phases are compared between a signal obtained
by frequency-diving an inputted non-return zero signal by
m and a signal obtained by frequency-dividing an extracted
clock signal outputted from a voltage control oscillator
by n. In addition, in order to correctly compare phases
between the frequency-divided signals, edge pulses used
for phase comparison and produced based on the frequency-divided
input signals are divided by an edge pulse
selecting circuit according to cases, specifically between
a case of performing phase comparison for the rising edge
of a frequency-divided clock and a case of performing
phase comparison for the falling edge of the same. Then,
phase comparison is performed based on each of the edge
pulses. The output of each phase comparison is passed
through a low pass filter to control the voltage control
oscillator.

Abstract: In a swing type excavator a horizontal pin 31 as the
coupling point between boom 14 and the swing post 13 is positioned
rearwardly of a swing pin 30 as the swing center
of the swing post 13 away from the front attachment. With
this arrangement, the so-called ultra-small or undercarriage-width
turn is realized without reducing both the side
ditch distance in a side ditch digging condition and the
maximum digging depth in a deep digging posture. Also, a
swing post 13 is attached to an upper structure 11, which
is able to turn within a width of an undercarriage 10, at a
position forwardly and laterally of a cab 12. A front attachment
1, including a bucket 22, an arm 19, an upper boom
17, a lower boom 14 and a cross link 15, is mounted to the
swing post 13. The cross link 15 intersects a line connecting
a coupling point between the upper boom 17 and the
lower boom 14 and a coupling point between the lower boom
14 and the swing post 13, and changes an opening angle between
the upper boom 17 and the lower boom 14 depending on
a vertical tilt angle of the lower boom 14. With this arrangement,
the upper structure including the front attachment
can be turned within the undercarriage width by a simple
construction with no need of using a complex link 
mechanism, and interference between the front attachment
and the cab can be easily avoided when the front attachment
is swung.
