Filed: 1992-12-17
Abstract: A method is provided for forming an improved poly-buffered 
LOCOS process by forming a pad oxide layer over a substrate. A 
first nitride layer is formed over the pad oxide layer and a 
polysilicon layer is formed over the first nitride layer. A second

Abstract: A data decoder, for example for decoding teletext and VPS data, comprises an input signal clamp and synchronising signal separate circuit (2) which receives a combined video and blanking signal and produces synchronising pulses for a timing circuit (4) and video signals applied to an ADC 6 and a data slicer and clock generator (7). Sliced data and clock signals feed an acquisition circuit (8) which acquires selected data which is stored in a memory (10). A control circuit 11 is arranged to modify the DSCR (7), acquisition circuit (8) and memory interface (9) in dependence on the type of data detected. The arrangement is such that the detector is set to decode data of one type, for example teletext, and if no valid data is detected within a given period, for example four television frames, the control circuit (11) causes the decoder to attempt to decode data of the other type (VPS). <IMAGE>

Abstract: A graphite-free lubricating oil which comprises a base oil 
having dispersed therein 10 to 40% by weight of a carbohydrate 
and/or a derivative thereof whose particle size ranges from 10 
to 150 µm, 2 to 20% by weight of a film-boosting agent and 0.1 
to 20% by weight of a dispersant. Moreover, the lubricating oil 
is free of black-colored substances such as graphite. 
Therefore, the oil permits the improvement of working 
surroundings and exhibits excellent properties such as 
formability through forging almost comparable to or even greater 
than that of the commercially available graphite-in-oil type 
lubricating oils. The lubricating oil can be used instead of the 
graphite-containing lubricating oils for warm forging, hot 
forging, rolling, tube-manufacturing, drawing and extrusion in 
place of the graphite-containing lubricating oils and ensures 
the improvement in the working surroundings and excellent 
lubricity.

Abstract: When reproducing an audio signal in an audio signal reproducing system, the unnaturalness in the quality of the reproduced sound, which is caused by the frequency spectrum of the audio signal is decreased or cut off at an upper limit of the reproducible frequency or at an upper limit of audible frequency range, is improved, so that a desirable sound in people's audio sense can be reproduced thereby. This is achieved by adding a random noise component and/or a higher harmonics component exceeding over the upper limit of the reproducible frequency range or the upper limit of the audible frequency range to the original audio signal in response to an output of the original audio signal. According to the invention, the reproduced sound becomes to have an excellent quality. <IMAGE>

Abstract: An antenna for use in a portable radio apparatus, which
has a pair of bands (2a, 2b) extending from the main body
(1) of the apparatus, for securing the apparatus to a user.
A first antenna conductor (21a or 21b) supplied with power
and a second antenna conductor (22a or 22b) not supplied
with power are embedded in each of the bands (2a, 2b) and
extend parallel to the axis of the band (2a or 2b). The
first and second antenna conductors (21a, 22a) embedded in
the first band (2a) are connected at one end to the first
and second antenna conductors (21b, 22b) embedded in the
second band (2b). No load is connected to the second antenna
conductor (22a or 22b) embedded in each band (2a or 2b).
The second antenna conductor (22a or 22b) embedded in each
band (2a or 2b) performs different functions according to
its length. If it has a length equal to or greater than
half the wavelength λ of waves to receive, it will function
as a reflector. If it has a length less than half the
wavelength λ of the waves, it will function as a director.
The four antenna conductors (21a, 21b, 22a, 22b) are adjusted
in length and position, constituting an antenna which has
high sensitivity and which is small enough to be incorporated
into a portable radio apparatus.

Abstract: A timing recovery system for a digital signal receiver receives a
signal, representing successive symbols, from a transmitter. The symbols
are subject to exhibiting multiple symbol rates. The system derives a
sample enable signal from the received input signal and employs a single,
fixed frequency oscillator. A source (10) of samples representing the
received signal are sampled at a fixed frequency. An interpolator (12) is
coupled to the sample source and is responsive to a control signal. The
interpolator produces samples taken at times synchronized to the
successive symbols from the transmitter. A phase error detector (16) is
coupled to the interpolator, detects a phase error between the sample
times of the transmitter synchronized samples produced by the interpolator
and times of the successive transmitter symbols, and supplies a
phase error signal. The phase error signal is coupled to one input
terminal of a summer (32) and a source (31) of a nominal delay signal is
coupled to the other. A numerically controlled delay (34-46) produces
the control signal for the interpolator in response to the signal from the
summer. An output signal from the interpolator is filtered by a fixed,
non-adaptive pulse-shaping filter (14).
