Abstract: A unified process flow for the fabrication of an 
isolated vertical PNP (VPNP) transistor, a junction field 
effect transistor (JFET) and a metal/nitride/polysilicon 
capacitor includes the simultaneous fabrication of deep 
junction isolation regions (36, 121) and a VPNP buried

Patent EP-0346618-A3 (EP)
IPC: A42B3/08
Filed: 1989-05-16
Abstract: A one-piece chinstrap-napestrap assembly (36) for a helmet (20) 
in which a pair of napestraps (42, 44) secured to the nape portion of 
the helmet interior at laterally spaced locations extend around 
the lower periphery of the helmet, crossing each other, and 
pass outwardly through slots (76, 78) formed in the front of the helmet 
to receive the ends of an adjustable chinstrap (40). Adjustment 
of the chinstrap (40) at the front of the assembly produces a simul­
taneous adjustment of the crossing napestrap portions at the 
rear of the assembly without the necessity for independent 
adjustment of the latter strap portions. A padded napestrap 
retainer (38) secured by straps (68, 70) 
to the same locations on the nape 
portion of the helmet is formed with intersecting passages (P1, P2) 
for receiving the crossing strap portions. The retainer (38) reduces 
chafing and urges the crossing napestrap portions toward the 
rear of the helmet (22) when the chinstrap (40) is released to facilitate 
donning and doffing.

Patent EP-0391135-A3 (EP)
Title: Web winding device
IPC: B65H18/26
Filed: 1990-03-21
Abstract: The method for controlling the pressure-roller setting of a web winder, which has become known as step control, is to be improved to the effect that even thin webs can be wound onto the winder spindle without being damaged. For this purpose, the pressure rollers bring the web as near as possible to the winder spindle, but without exerting pressure forces on the winder spindle, or only the pressure roller which is last in the web feed direction presses the web against the winder spindle, whereas the remaining pressure rollers lay the web as near as possible to the winder spindle, without exerting pressure forces on the web and the winder spindle. The slip-free laying of the web against the winder spindle is achieved by position-controlled spreading of the spindle segments.

Abstract: A pre-processing circuit is provided to receive a 
discrete-time speech signal which are then divided into a 
plurality of frames. A parameter extracting circuit is 
coupled to a pre-processing circuit to which a discrete-­
time speech signal is applied and extracts a plurality of 
parameters therefrom. A impulse response calculating 
circuit is coupled to receive the plurality of parameters 
from the parameter extracting circuit, and generates an 
impulse response function signal using the plurality of 
parameters. An autocorrelation function circuit is 
coupled to receive the impulse response signal and 
generates an autocorrelation function signal using the 
signal applied. A cross-correlation function signal 
generates a cross-correlation function signal using the 
discrete-time speech signal and the autocorrelation 
function signal. A grid signal generator receive the 
output of the cross-correlation function calculating 
circuit, and outputs a grid signal indicative of a 
location of a first excitation pulse within one frame. A 
pulse amplitude calculating circuit receives the 
autocorrelation function signal, the cross-correlation 
function signal and the grid signal, and determines an 
amplitude sequence of excitation pulses within one frame.

Title: Metallic pigments coated with synthetic resin, process for manufacturing them and their use
IPC: C09C3/10
Filed: 1990-12-10
Abstract: The invention describes novel metallic pigments coated with synthetic resin, which contain a siloxane coating, covalently bonded to the surface of the powder particles to which a three-dimensional cross-linked synthetic resin coat is covalently bonded. Such pigments can be obtained by production of an organosilicon coating of the pigment surface, subsequent conversion of this coating into a siloxane coating and subsequent reaction with a low molecular weight compound forming the synthetic resin coat. The metal pigments according to the invention are particularly suitable for the production of water-based lacquer, dye and paint compositions and in wet lacquers and powder lacquers for electrostatic lacquering and the colouring of plastics.

Title: Efficient digital frequency division multiplexed signal receiver
IPC: H03D3/00
Filed: 1990-01-04
Abstract: A digital intermediate frequency (IF) receiver for 
frequency division multiplexed (FDM) signals including 
analog circuitry for receiving FDM signals and an analog-­
to-digital (A/D) converter for converting the received 
signals to a sampled digital received signal. A digital 
complex mixer responsive to the digital output of the A/D 
converter translates the spectrum of the sampled digital 
received signal to center the desired FDM channel at zero 
frequency (DC). Digital low pass filtering isolates the 
desired channel centered at DC, and a digital complex 
mixer can be used to translate the isolated selected 
channel to a predetermined IF frequency. The in-phase 
portion of the digital IF centered selected channel or the 
DC centered complex envelope selected channel can then be 
provided to appropriate demodulation or decoder networks.

Title: Motor bearing assemblies
IPC: H02K5/167
Filed: 1990-04-05
Abstract: A sleeve bearing for a motor has a lubricant 
reservoir (16) formed by a high temperature resistant 
lubricant absorbed into a felt pad. An annular wall (15) 
extends axially of the motor and supports a part of the 
reservoir externally of the wall. Four imperforate 
channels (31 to 34) extend along the internal surface of 
the wall, tapering so that they are deeper adjacent the 
sleeve bearing where they open into the reservoir. The 
width of the channels is about 33% the total circumference 
of the wall. An O-ring (29) embracing the shaft (2) 
within the wall throws oil outwardly onto the wall so that 
it flows along the grooves into the reservoir. A PTFE 
washer (25) with a grooved surface is mounted on the shaft 
on the opposite side of the bearing.

IPC: G05D22/02
Filed: 1990-03-03
Abstract: Bei Dampfbadekabinen erfolgt die Wärmezufuhr zumindest 
zum Teil durch die Einleitung von Wasserdampf, wobei die 
einzuleitende Wasserdampfmenge in Abhängigkeit von der Innen­
raumtamperatur geregelt wird, um eine Überhitzung zu ver­
meiden. Da bei modernen, gut isolierten Dampfbadekabinen die 
Soll-Temperatur über einen längeren Zeitraum eingehalten 
wird, erfolgt eine Dampfzufuhr in relativ langen Zeitinter­
vallen, so daß zunächst der "sichtbare" Dampf berschwindet 
und dann durch Kondensation auch der Wasserdampfgehalt der 
Luft absinkt. Durch die Einleitung eines strömungsfähigen Kühlmittels, 
vorzugsweise in Abhängigkeit von der Nebeldichte im Innen­
raum, läßt sich eine Temperaturgleichgewichtslage unter 
gleichzeitger Erhaltung einer sichtbaren Dampfatmosphäre 
erreichen.
