Title: Gradient amplifier for magnetic resonance imaging apparatus
Inventor: LENZ HELMUT
IPC: A61B5/055
Filed: 1998-12-14
Abstract: The gradient amplifier is a power amplifier with at least one switching output stage (E) whose power bridge circuit comprises a number of switching devices (SE1 to SE4). A digital pulse width modulator receives digital input signals (IN, CLK, PHASE, SAFE, SE1SE4OFF, SE2SE3OFF, MODON, SOFTSOTP).  The pulse width modulated control signals (S1 to S4) replicate those of an analogue pulse width modulator. A pre-modulator is connected before the digital pulse width modulator and receives several input signals for the digital pulse width modulator. The output signals from the pre-modulator (PM1,PM2) are then fed to the digital pulse width modulator as input signals.

Patent DE-19859357-A1 (DE)
Inventor: KAMMERER MANFRED
IPC: G11B17/028
Filed: 1998-12-22
Abstract: The invention relates to a recording or reproduction apparatus with a holding and removing device for disc-type recording media which facilitates the emplacement and removal of the recording medium. According to the invention, the holding and removing device is formed by a cover of the hub of the disc turntable, by means of which, during the emplacement or removal of the recording medium, the holding force with which a recording medium is held on the disc turntable is reduced. The loading on the recording medium during emplacement or removal is thereby advantageously reduced and the special configuration of the cover as restoring means has the result that no additional individual parts are necessary. In an advantageous manner, the recording medium is both held and centred on the disc turntable with a force which is greater than a resistance encountered by the recording medium during emplacement or removal. The field of application of the invention extends to recording or reproduction apparatuses with a holding and removing device - provided on the disc turntable - for disc-type recording media, such as, for example, CD, CD-ROM or DVD drives.

Title: Verfahren und Vorrichtung zur Abbremsung eines Kraftfahrzeugs im Nahbereich mit einem Hindernis
Inventor: TROESTER HARRY
IPC: B60T7/22
Filed: 1999-01-07
Abstract: Bei einem Verfahren zur Abbremsung eines Kraftfahrzeugs im Nahbereich bei kleinen Geschwindigkeiten zur Vermeidung einer Kollision mit einem Hindernis werden der Abstand und die Relativgeschwindigkeit zwischen dem Fahrzeug und dem Hindernis sensorisch ermittelt und der Berechnung eines erforderlichen Bremsdruckes oder einer Verzögerung zugrunde gelegt. Der Bremsdruck wird zumindest teilweise fahrerunabhängig erzeugt. DOLLAR A Um die Reaktionszeit beim langsamen Heranfahren an ein Hindernis zu minimieren, wird für den Fall, daß die Relativgeschwindigkeit einen Schwellenwert und der Abstand eine Nahgrenze unterschreitet, das Bremsmoment auf einen kleineren Wert als das Motormoment eingestellt. Für den Fall, daß der Abstand eine Stoppgrenze, welche kleiner ist als die Nahgrenze, unterschreitet, werden das Bremsmoment und das Motormoment in der Weise eingestellt, daß das Bremsmoment das Motormoment übersteigt.

Abstract: The invention relates to a master cylinder (10) for a vehicle hydraulic braking system. Said master cylinder has a housing (12) with a bore (14) configured therein into which a first piston (24) and a second piston (26) are sealingly and displaceably located. Said second piston is arranged in an axial distance to the first piston. A positioning device (40) for a return spring (38) of the first piston (24) is arranged between the first piston (24) and the second piston (26).

Said pin-shaped component (44), at its side facing the sleeve-shaped component, has a flange (46) that protrudes radially outwards. The sleeve-shaped component (42) has a first U-shaped receiving flange (52) at its pertaining end that protrudes radially inwards. Said receiving flange (52) interacts with the flange (46) at the pin-shaped component (44) in a form-fit manner so that the two components (42, 44) cannot be axially moved apart. The sleeve-shaped component is provided with an introduction opening (54) in its surface area so that the flange (46) can be laterally introduced. Said introduction opening (54) is linked with the open section of the U-shaped receiving flange (52).

Title: Headlight for motor vehicle includes upwardly reflecting prism positioned at upper front edge of reflector which acts to deflect and emit portion of light from reflector in an upward direction when reflector is tilted to provide a high beam
Inventor: ISHIDA HIROYUKI
IPC: B60Q1/076
Filed: 1999-09-07
Abstract: The headlight includes an upwardly deflecting prism (40) that is mounted in the vicinity of the upper front edge of the lamp reflector (20). The reflector can be moved by a beam switching device (28) between a low beam position, where the light distribution pattern has a cutoff line, and a high position, where the prism acts to deflect and emit a portion of the light from the upper portion of the reflector over the cutoff line. The headlight has a reflector that emits light from a bulb (18) in a light distribution pattern that has a cutoff line by reflecting light forwards from the bulb, with the reflector being tiltably supported by a lamp body (14). A beam switching device selectively switches the beam between a low beam and a high beam by vertically tilting the reflector by a predetermined angle.  An upward deflection prism projects down from the above the reflector to a point in the vicinity of the upper, front edge of the reflective surface of the reflector and acts to deflect and emit part of the beam to a position over the cutoff line in conjunction with an upward tilting of the reflector when the low beam is switched to the high beam.
