Abstract:
In a latch circuit having a bistable pair of cross connected transistors of a first polarity and a third transistor of a second polarity, a current signal greater than a bias current is received at a latch circuit port, amplified with the third transistor, and applied to the latch circuit port. This decreases the time in which the latch circuit port receiving the current signal greater than the bias current reaches a steady state voltage.

An analog to digital converter includes a reference ladder, a track-and-hold amplifier tracking an input signal with its output signal during the phase &psgr;1 and holding a sampled value during, a coarse analog to digital converter having a plurality of coarse amplifiers each inputting a corresponding tap from the reference ladder and the output signal, a fine analog-to-digital converter having a plurality of fine amplifiers inputting corresponding taps from the reference ladder and the output signal, the taps selected based on outputs of the coarse amplifiers, a clock having phases &psgr;1 and &psgr;2, a circuit responsive to the clock that receives the output signal, the circuit substantially passing the output signal and the corresponding taps to the fine amplifiers during the phase &psgr;2 and substantially rejecting the output signal and the corresponding taps during the phase &psgr;1, and an encoder converting outputs of the coarse and fine amplifiers to an N-bit digital signal representing the input signal.
Abstract:
A hot-gas reciprocating machine having a free piston, one face of which varies the volume of a working space while its other face bounds a buffer space of constant pressure. A control mechanism maintains a constant nominal central piston position by momentarily connecting the working space and the buffer space.
Abstract:
A pressing block for a phonograph or video record press in which ducts for cooling and heating media for the die are formed by a thin layer of a porous heat-conducting material provided between two thin metal sheets and bonded thereto. The assembly is connected on its side remote from the die to a supporting element of at least partially heat-insulating material.
Abstract:
A cold-gas refrigerator of the type in which the displacer is driven by pressure fluctuations generated in the working medium, the piston being coupled to an a.c. supplied linear actuator; the system formed by piston/armature coil assembly of the actuator and working medium resonates at a frequency which is tuned to the alternating current frequency.
Abstract:
An electrical circuit comprising a line driver for providing Ethernet signals is disclosed. The line driver comprises a voltage mode line driver for producing 1000BT and 100BT Ethernet signals and an active output impedance line driver arranged parallel to the voltage mode line driver. The line driver is capable of producing 1000BT or 100BT or 10BT Ethernet signals, wherein either the voltage mode line driver or the active impedance line driver is active.
Abstract:
An apparatus, a method, and a system are provided to calibrate an offset in an amplifier. The apparatus can include an amplifier, a voltage control unit, a comparator, and a processing unit. The amplifier can have four terminals: a positive differential input (VIN+), a negative differential input (VIN−), a positive differential output (VOUT+), and a negative differential output (VOUT−). The voltage control unit can be configured to adjust a first voltage on VOUT+ and a second voltage on VOUT−. The comparator can be configured to compare the first voltage on VOUT+ to the second voltage on VOUT− when VIN+ and VIN− are coupled to a common voltage. Further, the processing unit can be configured to provide a control signal to the voltage control unit based on the comparison of the first and second voltages on VOUT+ and VOUT−, respectively.
Abstract:
The invention relates to a device for coating a plurality of substrates (3) which are regularly arranged on a bearing surface (2) of a susceptor (1) associated to a process chamber (14), wherein the bearing surface (2) forms abutment flanks (5) for the edge mounting of each substrate (3). In order to reduce the free susceptor surface to a minimum, it is proposed that the abutment flanks of the lateral walls (5) are formed by bases (4) which project from the bearing surface (2) and are separated at a distance from one another. Said bases are arranged on the corner points (10) of a honeycomb structure and have an outline essentially corresponding to an equilateral triangle with inwardly curved sides (5).

The invention refers to signal processing circuits, more particularly, to switch capacitor circuits, and methods for reducing inter-symbol-interference. A switch capacitor circuit with reduced Inter-Symbol-Interference effect is provided, comprising: a voltage source, a first capacitor, a second capacitor, and at least one switch configured to be switched in a way that the first capacitor is charged to a first voltage by means of the voltage source, and then discharged by means of the second capacitor, thereby reducing the Inter-Symbol-Interference effect.
