Publication number: 20110209324Abstract: In a method for detaching wafers from a carrier unit, the wafers being formed by sawing a wafer block fastened to the carrier unit by gluing, and the wafers themselves still being glued on one side, the carrier unit with the wafers is introduced into an ungluing unit along a uniform movement plane. It remains therein and is enclosed in an ungluing basin by movable wall parts. Solvent for ungluing is applied into the ungluing basin and onto the wafers after the formation and closing of the ungluing basin to dissolve the glued bond and subsequently detach the wafers from the carrier unit.Type: ApplicationFiled: April 15, 2011Publication date: September 1, 2011Applicant: Gebr.

Patent number: 5953480Abstract: A comb filter arrangement comprising at least one delay circuit and an adder, this adder being twice supplied with a video signal modulated on a carrier, which video signals are applied mutually shifted with time. The signals are delayed by the delay circuits, so that either video signal applied to the adder is delayed relative to the other video signal by a given period of time. Furthermore, the delay circuits are arranged in switched capacitor technique.Type: GrantFiled: July 11, 1996Date of Patent: September 14, 1999Assignee: U.S. Philips CorporationInventors: Cord-Heinrich Bartels, Thomas Suwald, Sonke Struck, Jorg Wolber

Patent number: 5335018Abstract: A digital phase-locked loop (PLL) which responds to a square-wave input signal of on expected frequency f.sub.E and comprises a change-over switch which is switched in response to square-wave signals or different frequencies and precedes a main divider operating with a divisor D and which produces the output signal of the phase-locked loop. The change-over switch is activated as a function of the output signal and the input signal. In order to provide symmetrical locking in of the phase-locked loop and a small capture-and-hold range, the change-over switch is switched between a first square-wave signal of the frequency f.sub.1, a second square-wave signal of the second frequency f.sub.2 and a third square-wave signal of the frequency f.sub.3, in which:f.sub.1 .multidot.1/D=f.sub.Eandk.multidot.f.sub.1 =f.sub.2 +(k-1).multidot.f.sub.3,A switching logic is provided which controls the change-over switch in such that it is switched to the signal of the first frequency f.sub.Type: GrantFiled: October 25, 1993Date of Patent: August 2, 1994Assignee: U.S. Philips CorporationInventors: Ulrich Mohlmann, Gerd Onken, Dieter Kunze, Jorg Wolber

Patent number: 5254993Abstract: A multiplying digital-to-analog converter which includes an R-2R chain network is characterized in that, for partial or complete potential equalization, the chain network for an n-bit-wide digital signal applied to the converter comprises (n+m) connection points, where n,m are natural integers greater than zero, the connection point (n+m) produces the output signal of the converter. A first current mirror is provided which produces a constant first current that can be switched to the individual connection points (1+m) to (n+m). The least significant bit of the digital signal is allocated to the connection point (1+m) and the most significant bit to the connection point (n+m) and the first current is switched only to those connection points whose allocated bit has a first state.Type: GrantFiled: September 4, 1992Date of Patent: October 19, 1993Assignee: U.S. Philips CorporationInventors: Jorg Wolber, Klaus Kroner

Patent number: 4883991Abstract: A circuit arrangement for amplifying a periodic signal and for adjusting a reference level contained therein, in which a charging/discharging arrangement alternately supplies charging or discharging currents to a storage means, depending on whether the value of a periodic signal exceeds or is exceeded by a limit value, such that a mean value at least substantially corresponding to the reference level occurs at the storage means includes a compensator means which adjusts the charging and disharging currents by a compensation factor which is selected such that the ratio of the charging current to the discharging current is independent of fluctuations in current resulting from variations affecting the gain factors of amplifier components comprised in the amplifier means.Type: GrantFiled: June 4, 1987Date of Patent: November 28, 1989Assignee: U. S. Philips CorporationInventors: Klaus G. Kroner, Jorg Wolber

Patent number: 4868429Abstract: A circuit arrangement for deriving an output current from an input current, which output current is limited to a current range which is bounded by at least one limit value. It is possible to limit high-frequency currents by avoiding current distributions or saturation effects in that the circuit arrangement comprises a current combination element (1) for forming an at least substantially linear combination of the input current (IE), the output current (IA) and a fixed reference current (IR) and by at least a rectifier circuit (2) arranged in the current path of the input current (IE) and/or the output current (IA).Type: GrantFiled: March 15, 1989Date of Patent: September 19, 1989Assignee: U.S. Philips CorporationInventors: Jorg Wolber, Klaus G. Kroner

Patent number: 4752833Abstract: A circuit arrangement for a video recorder comprises a modulator (5) for modulating a chrominance signal from a first onto a second carrier wave by means of a third carrier wave. In order to generate the third carrier wave a first mixer (39) is coupled to a reference oscillator (18) and to a first voltage-controlled oscillator (23). A control signal from a phase-comparator circuit (15), which compares the frequency and phase of the burst signal with these of the first oscillator signal, and a control signal from a phase-comparator circuit (30) of a phase-locked loop in which a second voltage-controlled oscillator (27) is synchronized with the line synchronizing pulses, are applied to the first voltage-controlled oscillator (23). The two voltage-controlled oscillators are substantially identical and have a fixed frequency ratio with each other.Type: GrantFiled: June 5, 1986Date of Patent: June 21, 1988Assignee: U.S. Philips CorporationInventor: Jorg Wolber

Patent number: 4745493Abstract: A circuit arrangement for a color image recording and reproduction instrument(video recorder) or a color television receiver. Such devices have a phase regulation circuit in which an oscillator (18, 59) is controlled in accordance with the phase comparison between the color synchronization signal and a reference signal performed in a phase comparator circuit (9, 40). A control signal from the phase comparator circuit is applied to at least two scanning and locking units (12, 13; 49 to 52) which can be changed over successively and cyclically. These units scan the control signal during the color synchronization blanking time. The output signals of the scanning and locking units (12, 13; 49 to 52) are applied to an adder (16, 54) coupled to the oscillator (18, 59). The interference signals arising from the PAL changeover and superimposed on the control signal are thus eliminated.Type: GrantFiled: July 17, 1986Date of Patent: May 17, 1988Assignee: U.S. Philips CorporationInventors: Karl Gedl, Jorg Wolber

Patent number: 4075570Abstract: A circuit is shown for compensating for rapid changes in D.C. levels in high pass filter coupled vertical deflection circuits. It features a second high pass filter that applies a D.C. signal having a second level change so that the first change is cancelled out.
