Title: Verfahren und Vorrichtung zum Prüfen von Nutzfahrzeugachsen mit Federn
IPC: G01M13/00
Filed: 1989-05-29
Abstract: Mit der Erfindung werden ein Verfahren und eine Vorrich­
tung zur Prüfung von Nutzfahrzeugachsen und/oder -federn 
und deren angrenzenden Komponenten unter betriebsähnlichen 
Belastungsbedingungen zur Verfügung gestellt. Es wird eine 
gesamte Nutzfahrzeugachse mit zwei Nutzfahrzeugfedern und 
Originalanbauteilen durch Einleiten von niederfrequenten 
Verformungen bzw. Vertikalkräften an einem Halterungsauf­
bau, sowie von Seitenkräften, Längskräften und hochfre­
quenten vertikalen Radkräften an je einem Radersatz oder 
Rad bzw. an je einem Bremskrafteinleitungshebel geprüft, 
wobei der Halterungsaufbau bei der Prüfung um einen in 
vertikaler Richtung verschiebbaren Drehpunkt bzw. um eine 
in vertikaler Richtung verschiebbare Drehachse geneigt 
wird, so daß die Nutzfahrzeugachse parallel zur Horizon­
talen bleibt. Vertikale Einfederung und Neigung des Hal­
terungsaufbaus wird durch zwei Vertikalkrafterzeuger, die 
am Halterungsaufbau angreifen, hervorgerufen, welche ver­
tikale Reaktionskräfte im Radaufstandspunkt der Vertikal­
kraftabstützung erzeugen. Zur Prüfung von Nutzfahrzeug­
federn alleine wird anstelle von zwei Seitenkrafterzeu­
gern nur einer verwendet, und zur Einleitung von Brems­
und Antriebskräften und/oder Längskräften wird ebenfalls 
anstelle von zwei Brems- und Antriebskrafterzeugern und/­
oder zwei Längskrafterzeugern jeweils nur einer dieser 
Krafterzeuger verwendet, wobei dieser dann in Achsmitte 
über eine Krafteinleitung wirkt, die an dem rechten und 
linken Radersatz bzw. an dem rechten und linken Brems­
krafteinleitungshebel befestigt ist.

Title: Hydrostatic speaker and speaker driver
IPC: H04R23/00
Filed: 1989-06-09
Abstract: A hydrostatic speaker includes an 
oscillator (4), a partition diaphragm (5) disposed in 
the oscillator (4) to divide the oscillator (4) into 
two chambers (6, 7), at least one (6) of which 
chambers (6, 7) seves as a fluid chamber to cause the 
partition diaphragm (5) to vibrate in response to 
external signals from a source (12), an acoustic sound 
radiation core (1) connected with the partition 
diaphragm (5) via a rod (9), a sensor (10) for 
detecting fluid pressure in the fluid chamber (6) and 
another sensor (11) for detecting a movement of the 
diaphragm (5). The hydrostatic speaker is provided 
with a speaker driver which includes a fluid pressure 
controller (14) connected to a pressure source (17) 
for controlling the fluid pressure in the fluid 
chamber (6), and a control amplifier (13) for 
controlling the fluid pressure controller (14) in 
accordance with the external signals. Signals detected 
by the pressure sensor (10) and the position sensor 
(11) are respectively input as feedback signals to 
the control amplifier (13) in order to improve 
controllability, to reduce noise due to pressure 
fluctuation in the pressure source (17), and to 
improve a neutral positioning of the diaphragm (5). 
The hydrostatic speaker can radiate super low-­
frequency sound, which has been considered difficult 
by conventional speakers.

Filed: 1991-06-19
Abstract: A method for adjusting conditions comprises the 
steps of, when a radiation image of a specific object is 
recorded and read out, investigating whether recording 
and read-out operations were or were not carried out in 
the past for the same object as the specific object. 
When recording and read-out operations were carried out 
in the past for the same object as the specific object, 
image recording conditions for the specific object are 
adjusted such that they coincide with those under which 
the recording operation was carried out for the same 
object as the specific object. Also, instead of read-out 
conditions for a final readout, which is to be carried 
out for the specific object, being adjusted on the basis 
of a preliminary read-out image signal representing the 
radiation image of the specific object, the read-out 
conditions for the final readout to be carried out for 
the specific object are adjusted such that they coincide 
with those under which the final readout was carried out 
from the radiation image of the same object as the 
specific object. Recording and read-out operations for 
the specific object are carried out under the conditions, 
which have thus been adjusted.
