Abstract: The interface chip (SLIC) of the subscriber connection circuit is divided into a high-voltage chip (HV) and into a low-voltage chip. During times free of activity, the high-voltage chip is switched off. In the low-voltage chip, one of the two supply voltages is supplied via a switch (S, R) which is bypassed with a high resistance. This makes it possible to achieve further reduction in power dissipation during times free of activity without inadmissible voltage displacements occurring at the interface (dS) between low-voltage chip and central control unit (St) because of the second supply voltage which cannot be switched off for reasons of expenditure. <IMAGE>

Inventor: ROY PRADIP KUMAR
IPC: H01L21/316
Filed: 1989-12-11
Abstract: A method is disclosed for growing relatively thin (e.g., <25 nm) thermal oxides which results in lowering the defect density, mobile ion concentration, interface trapped charge density, and stress of the structure. In particular, the prior art oxidation process is modified to include  in situ  preoxidation silicon surface treatments to improve the silicon nucleation surface. For example, gettering operations may be performed to remove metal-ion contaminants from the silicon nucleation surface, and high temperature annealing operations may be performed to remove any local stress gradients which exist in the silicon substrate during the initial stages of oxidation. By improving the silicon nucleation surface, the subsequently grown thin oxide will be improved in terms of the qualities mentioned above.

Abstract: The invention relates to a circuit arrangement for a freely oscillating isolating transformer switched-mode power supply having a control device (IC) for the pulse-width-modulated triggering of an electrical switching element (T1). As control information, this control device (IC) receives, inter alia, on an input terminal (8) a zero passage detector signal (Uzero) and, on a further input terminal (1), a control voltage (UR), which is dependent on the output voltage (UA) of the switched-mode power supply. In order to ensure reliable operation of the circuit arrangement, even in the event of low power consumption and especially in the standby mode with only a few watts no-load power, it is proposed to provide, in addition to a capacitive coupling of the two input terminals (1, 8), a detector device (DE) with whose aid an internal reference voltage (Uref) of the control device (IC) can be reduced in the standby mode. By this means, the increase in the output voltage, which is undesired in the standby mode and is increased even further by the capacitive coupling, can effectively be avoided.

Abstract: An infant environmental transition system and method provides an infant with a controlled, healthy transition from an intrauterine environment to the extrauterine environment, and includes a housing (1) within which the infant is supported by a soft, form-fitting bed (33). Environmental conditions provided within the housing include simulated motions, sounds and tactile sensations resembling the intrauterine environment. A suspension and drive system controls the degree of movement imparted to the housing and to an infant supported therein. The resulting motion closely approximates the motion experienced by the fetus while the mother is walking. The sound profile simulates intrauterine cardiovascular and gastrointestinal sounds. The system simulates day and night variations in motions and sounds, integrates changes to the environment over time toward the natural extrauterine environment, and may respond to infant activity or other imputs at various intervals.

Abstract: A luminance interpolation type waveform display apparatus is arranged in such a manner that a supplied waveform signal (A) is successively sampled and amplitude data (Dn, Dn+1, ...) of each time-base address (Tn, Tn+1, ...) corresponding to a display frame is stored by a memory (2). A serial dot data processing means (3) successively reads the amplitude data of the adjacent time-base address from the memory (2). The serial dot data processing means (3) connects the amplitude data items so as to linearly interpolate the luminance in synchronization with a clock. The apparatus contains a bit map memory (4) having two ore more regions which can be shifted and written in each amplitude address of the respective time-base address in synchronization with the clock input. The two or more regions are capable of being simultaneously set to a reading mode and a writing mode. These modes are alternately switched so that when the serial dot data (SDn, SDn+1, ...) is written in one region in a direction perpendicular to the direction of the time-base address (Tn, Tn+1, ...), another region is read in the direction of the time-base address and the waveform is displayed on a waveform display apparatus (6) by raster scanning.

Filed: 1990-10-26
Abstract: A process of forming field oxide regions using a field oxidation performed in a dry oxidation environment in a temperature equal to or greater than approximately 1000°C. The dry oxidation reduces or eliminates the formation of Kooi ribbons, and the high temperature field oxidation allows the field oxide to flow, thereby reducing physical stresses normally associated with field oxidation performed at temperatures below 1000°C. The high temperature field oxidation also greatly reduces the ratio of the length of the bird's beaks formed during the field oxidation to the thickness of the field oxide, allowing smaller active regions to be formed. The thinner field oxide regions, in turn, make it possible to perform the field implant after the field oxidation, thereby avoiding the lateral encroachment problem and controlling source to drain or drain to source punch-through under the gate. Further, the high temperature field oxidation allows the well implant drive and the field oxidation to be performed simultaneously.
