Patent EP-0845867-A2 (EP)
Inventor: EASTTY PETER CHARLES
IPC: H03M7/32
Filed: 1997-10-30
Abstract: A signal processor for 1-bit signals comprises a fifth order Delta-Sigma
Modulator (DSM) having an input 4 for receiving a 1-bit signal and an output 5 at
which a processed 1-bit signal is produced by a quantizer Q. The quantizer Q
receives a p-bit signal from a series of 5 signal integration stages. Each stage
comprises a first 1-bit multiplier An coupled to the input 4, a second 1-bit multiplier
Cn coupled to the output 5, an adder 6n which sums the outputs of the coefficient
multipliers and an integrator 7n which integrates the output of the adder 6n. A final
stage comprises a coefficient multiplier An+1 and an adder 6n+1. The adder 6n+1
sums the output of the coefficient multiplier An+1 and the output of the integrator
of the preceding integration stage. The coefficients An and Cn are chosen to provide
an overall attenuation of the input signal and of the quantization noise produced by
the quantizer and also to provide a low pass filter which provides a compensating gain
to the input signal. In this way the quantization noise outside the band of the input
signal is reduced. Reduction of quantization noise enhances stability of the circuit
and also allows several DSMs to be connected in series by preventing the build-up
of excess noise which may compromise stability.

Abstract: An iron is provided with heat buffering spacers (50) which
vertically set apart component elements (12,20,34,35) in a
stacked arrangement. The spacers (50) cause gaps between
stacked parts thus allowing for improved air convection
through the iron as well as spacing the metallic heated
elements from the thermoplastic elements which attach to it
to prevent melting.

Abstract: The invention relates to microcircuit packaging techniques, and more
particularly to the packaging of a structure compiled of several microcircuits.
In an arrangement according to the invention, unpackaged components (2) are
mounted on a substrate (20), and to the substrate (20) there is attached a tape
(4); on the side of the tape directed away from the substrate, there are formed
solder bumps (10). By means of the solder bumps (10), the whole structure can
be mounted to a circuit board by applying conventional surface-mounting
techniques. The connections between the solder bumps (10) and the I/O lines
of the substrate are realised by means of conductive patterns formed on the
tape, and by means of leads (14) provided at the edges of the tape. By
employing the tape, it is possible to realise various different connections in a
versatile manner, for instance connections between the substrate (20) and
solder bumps (10), between components (2) and solder bumps (10), between
components (2) and the substrate (20) as well as between single components
(2).

Abstract: It is an object on the invention to provide a SAW device
sealed by resin, which is low priced and suited for decreasing
its thickness and weight and requires no particular course for
processing a substrate, and a method for fabricating the same.
A functional surface of a piezoelectric substrate provided with
interdigtal transducers and a mounting surface of a circuit
substrate are opposed to each other to form vibration cavities
for surface wave propagation areas therebetween. Electrical
power is supplied to the piezoelectric substrate from the
circuit substrate via electrode pads formed on respective inner
surface of both the substrate and bumps inserted therebetween.
A resin film adheres to the respective inner surfaces of both
the substrates except the surface wave propagation areas to
shield the vibration cavity from the environmental space.
Apertures are previously formed at predetermined parts of the
resin film by means of a laser. A resin film is temporarily
adhered to the inner surface of the circuit substrate for
instance, and positioning of both the substrates are adjusted
relative to each other. Thereafter, both the substrates are
permanently adhered to each other by hot-pressing them, and
sealing is completed.

Abstract: A demand responsive flow control valve including a housing in a
fluid conduit between a pump and a motor vehicle power steering gear, a flow
control orifice in the fluid conduit, and a valve pintle supported on the
housing for linear translation. An inboard stop on the housing engageable by
the valve pintle defines an active position of the valve pintle, obstructing the
flow control orifice and reducing the effective area of the latter. The inboard
stop is a tubular sleeve interference fitted in a bore in the housing. The
position of the tubular sleeve on the housing corresponding to the active
position of the valve pintle is established by inducing linear translation of the
tubular sleeve into the bore in the housing as a unit with the valve pintle while
monitoring the corresponding flow rate through the fluid conduit. When the
actual flow rate attains a magnitude equal to a desired or scheduled low flow
of the flow control valve, the corresponding calibrated position of the tubular
sleeve is rigidly captured by friction attributable to the interference fit
between the tubular sleeve and the housing.
