Patent EP-0204263-A3 (EP)
Title: Rotary-piston pump
IPC: F04B7/06
Filed: 1986-05-29
Abstract: Both the rotating drive and also the back and forth movement of the pump piston (5) occurs through a joint arrangement (29), which consists of a first through (65) on the crank (28), a second trough (67) on the piston (5) and a rolling member (30) which is received in the troughs (65, 67). The troughs are pressed by a springy ring (68) against the rolling member (30). The troughs (65, 67) have a slightly smaller curvature than the rolling member (30), so that the rolling member (30) rolls in the troughs (65, 67). Friction in the joint arrangement (29) is avoided through this, which results in a long life of the joint arrangement (29).

IPC: H01L21/28
Filed: 1986-08-01
Abstract: A self-aligned split gate single transistor memory cell 
structure is formed by a process which self aligns the drain 
region to one edge of a floating gate. The portion of the 
channel underneath the floating gate is accurately defined 
by using one edge of the floating gate to align the drain 
region. The control gate formed over the floating gate 
controls the portion of the channel region between the 
floating gate and the source to provide split gate 
operation. The source region is formed sufficiently far 
from the floating gate that the channel length between the 
source region and the closest edge of the floating gate is 
controlled by the control gate but does not have to be 
accurately defined.

Title: Method for the dry regeneration of a catalyst
IPC: B01J38/00
Filed: 1987-04-10
Abstract: A method for the dry regeneration of a deteriorated catalyst formed in the shape of a large number of tubes, a honeycomb, or a large number of plates is disclosed wherein an abrasive material is used to grind the surfaces of the interiors of the many holes in the deteriorated catalyst, additional aspects of the method include using silica sand for the abrasive material; causing the abrasive material to flow through the interiors of the catalyst holes on a current of air; to flow through the interiors of the catalyst holes by its own weight and by vibration. In addition the abrasive material may consist of brushes, may be sandpaper, or may consist of files. In al alternative method, a catalyst edge protection grid is first placed on top of the deteriorated catalyst, and then the abrasive material is caused to flow through the interiors of the catalyst holes in order to grind the interior surfaces of the catalyst holes.

IPC: A61B10/00
Filed: 1987-06-10
Abstract: A pulse sequencer (40) controls a resonance 
excitation controls circuit (22), an inversion pulse 
controls circuit (24), a slice select gradient controls 
circuit (32), a read gradient controls circuit (34), and 
a phase encode gradient controls circuit (36) to cause 
an appropriate gradient pulse imaging sequence to be 
generated to the image region. The operator selects an 
appropriate imaging sequence such as a spin echo, 
inversion recovery, multi-echo, gradient echo, or other 
conventional imaging sequence and the parameters, such 
as the number of repetitions, from an image pulse 
sequence and motion desensitization memory (44, 46). In 
the exemplary pulse sequences of FIGURES 2-4, this 
memory directs the formation of RF pulses (62, 66), 
slice selection pulses (60, 64) and read gradient pulse 
(70), phase encode gradient pulse (72), and the 
appropriate additional gradient pulses for rephasing 
signals from one or more of static, constant velocity, 
accelerating, and pulsatilitory tissue in the image 
region. By rephasing the magnetic resonance signal 
components from tissue moving with the selected motion 
characteristics such that the corresponding moments in 
time are set equal to zero, motion artifacts from moving 
tissue are suppressed.

Title: High frequency power amplifier having heterojunction bipolar transistor
IPC: H03F3/19
Filed: 1988-03-11
Abstract: A class C power amplifier has a heterojunction 
bipolar transistor (10) as an element for amplifying an 
input signal. A d.c. bias voltage source (20), such as 
a d.c. battery, is connected to the transistor (10), 
such that a d.c. bias voltage lower than the turn-on 
voltage of the transistor is applied between the base 
and emitter of the bipolar transistor (10). An induc­
tance coil (22) is connected in series between the 
emitter of the transistor (10) and the d.c. bias voltage 
source (20). Since the d.c. bias voltage is applied to 
the heterojunction bipolar transistor, the external 
drive voltage for activating the transistor (10) is 
reduced to increase the high-frequency power gain of the 
amplifier.
