Patent EP-0307064-A3 (EP)
Title: Magnetic resonance imaging method utlizing small excitation pulses
Inventor: MEULEN PETER VAN DER
IPC: G01R33/561
Filed: 1986-06-11
Abstract: A magnetic resonance method is known with cycles 
comprising a 90° excitation pulse and gradient recalled echoes wherein 
after each excitation and sampling of the recalled echoes a waiting time 
is introduced for having magnetization return to thermal equilibrium. In 
said method the cycles are applied with a time integral of a phase 
encoding gradient getting successive magnitudes from a minimum to a 
maximum value in a number of successive cycles in order to obtain data 
for forming an image e.g. representing proton densities in an object to 
be examined.  
     A magnetic resonance method is suggested with α° 
excitation pulses where 0<α<90°, and gradient recalled echoes whereby 
there is no substantial waiting time between successive excitation 
cycles, so that a steady state equilibrium of magnetization will occur, 
and whereby a best possible image quality is obtained by assigning 
magnitudes in a sequence of decreasing absolute values over a number of 
measurement cycles. Signal sampling takes place from the first 
measurement cycle i.e. there is no waiting for steady state conditions. 
This implies e.g. amplification of the highest image frequencies giving 
a better edge definition in the image so that image quality is improved.

IPC: H04R3/12
Filed: 1988-08-26
Abstract: Surround stereo signals are synthesized from the 
composite or DME monaural sound tracks of audiovisual 
programs by use of multi-channel, computer-controlled 
digital circuitry and operator-programmed sound cues, the 
latter matching video time codes with audio control 
signals. The stereo signals have out-of-phase delay 
components, resulting in compatibility with conventional 
monaural audio equipment, and steerable pan components, 
resulting in selective sound placement capability. 
Variable time delays and variable ratios of dry and delay 
are used in conjunction with panning movements to acheive 
a wide variety of acoustical effects, such as resonance, 
spread and cutting, which correlate the audio portion of 
the program with the video portion of the program. An 
operator selects and programs sound cues and stores them 
for playback by using a plurality of audio controls and a 
computer interface which are provided on an operator 
console. Subroutines are used for automated cue 
recording and for editing. Stereo sound tracks are 
created from monaural source material.

Abstract: A stop mode setting apparatus comprises a system 
controller having time measuring means, and a driver for 
driving a capstan motor in response to a control signal from 
the system controller. When given a command for a change 
from a play mode to a stop mode, the system controller 
reversely rotates the capstan motor only for a period of 
time determined by the time measuring means, thereby causing 
a swing idler to perform a swinging motion. During this 
swinging motion, a magnetic tape is moved from the capstan 
toward a head cylinder and given a suitable slack at the 
portion thereof between the capstan and the cylinder.

Title: Injection moulding machine and method of regulating the clamping force of an injection moulding machine

Filed: 1989-10-27
Abstract: A method and apparatus for controlling the 
hydraulic pressure in an hydraulic clamping cylinder (32) 
to correspond with a desired clamping force and to 
compensate for overshoot of the hydraulic pressure caused 
by time delays in operating the components in the hydraulic 
circuit. The control arrangement involves the sensing (86) of 
the actual hydraulic pressure (PA) during the clamp force 
maintenance portion of a clamping cycle and comparing (88-90) the 
actual pressure (PA) with a desired pressure (PD) to provide a 
correction signal (ΔP) to be utilised to control the operation 
of the hydraulic system during the next succeeding cycle so 
that the actual hydraulic pressure (PA) during the clamp 
maintenance position of the clamping cycle during the next 
succeeding cycle results in a clamping force that is closer 
to the desired clamping force.

Patent EP-0377300-A3 (EP)
IPC: H03H21/00
Filed: 1989-12-20
Abstract: An input propagation lumped element network (41) has a 
frequency response selected from responses consisting of a band pass 
filter response, a low pass filter response, and a high pass filter 
response, and an output propagation network (44) has a frequency 
response selected from the group of frequency responses consisting 
of a low pass frequency response, a high pass frequency response, 
and a band pass frequency response. Weighting means (42) comprising 
a plurality of field effect transistors (FET1-FET5) are used to 
successively couple the input propagation network (41) and the 
output propagation network (44). By using lumped element filter 
networks (41, 44), the general shape or response of the transversal 
filter (51′) is provided by choosing the characteristics of the 
input and output propagation networks (41, 44) in relation to the 
desired filter response. With the general shape provided by the 
propagation networks (41, 44) rather than by the transversal 
elements (FET1-FET5), fewer transversal elements are required in the 
transversal filter (51′) to provide a desired response. Thus, the 
transversal filter has a physically smaller size than a conventional 
transversal filter, thereby increasing the manufacturability of the 
circuit and reducing the cost of the circuit particularly when said 
circuits are fabricated as monolothic microwave integrated circuits. 
For transversal filters having a bandpass characteristic, harmonic 
sub-bands generated at high frequencies are eliminated by use of 
lumped element networks having cutoff frequencies coinciding with 
the frequency skirts or bandedges of the filter. In a recursive 
filter (Fig. 11), one or more of the transversal elements (FET1-­
FET5) are replaced by recursive elements (RR2) such as resistors 
providing feedback connectors between the output and input 
networks (44, 41).

system can be introduced any time before the polycondensation stage of 
the manufacturing process.
