Patent EP-0451587-A2 (EP)
Inventor: VARASI MAURO
IPC: C23C14/32
Filed: 1991-03-24
Abstract: Method for the deposition of thin films having high adherence, density, stability, absence of optical scattering and mechanical resistence characteristics. 
     It belongs to the field of thin film growth techniques (0.01 to 10 microns) for application to optics, integrated optics, microelectronics and metallurgy. 
     The method consists in the adoption of a system for the deposition under vacuum from a thermal source or electronic cannon and an RF power generator (13.6 MHz Radio Frequency) connected through an impedence adapter network to the substrate carrier which equips the deposition system. 
     The power of the generator allows to maintain a RF discharge in a gas input to the deposition system at a pressure of 1 10 mtorr. 
     Having a suitable condenser in series with the adapting network and the substrate carrier, it is in negative auto bias situation equal to about 45-48 % of the peak to peak RF discharge. This condition is imposed by the minor mobility of the ions compared to that of the plasma electrons and therefore also by the average electrical charge equal to zero on the electrodes of the RF discharge. In this situation the substrate resting on the substrate carrier is bombarded by the ions generated during the discharge and it simultaneously condenses the material evaporated by the thermal source or by the electron cannon. 
     This simultaneous bombardment at energies variable between 100 and 400 electron volts provides considerable improvements in the optical and mechanical characteristics of the films deposited.

Abstract: A base voltage of a regulator transistor (Q2) is developed during normal operation in a filter capacitor (C2) coupled to a flyback transformer (24) of a horizontal deflection circuit (Q5,LY,C S ). After a transition to a standby mode of operation, the deflection circuit is disabled and the capacitor begins discharging. The emitter of the transistor is coupled to a load circuit (L3). A supply voltage (+V₁) is coupled to the collector of the transistor during both standby and normal mode. To reduce the loading of a standby power supply that generates the collector voltage as long as the capacitor is not fully discharged, an active turnoff (Q3) of the regulator transistor is provided immediately after the receiver goes into the standby mode of operation so as to actively turnoff the current drawn by the transistor.

Abstract: In a fault diagnostic system an operator interface (25, 30) simultaneously displays an operations hierarchy (60) and a components hierarchy (50) in two separate windows (200, 210). The display system is used with a model-based diagnostic system (10, 95) that monitors operational parameters of an industrial process (20). The diagnostic system (10, 95) identifies possible failure source components in the industrial process (20) an the display system (25, 30) uses these diagnostics to display the most interesting portions of the operations hierarchy and the components hierarchy. The most interesting node, to be displayed with its subtree, is defined as the node at the lowest level of the hierarchy that is both a fault source and that has more children than other fault sources at that level.

Abstract: A diverter valve has an IN port (33) and first and second OUT ports (35,37) which are positioned along an arcuate path. A rotor (20) has an external control knob and a stem extending within the cavity of the valve body. Mounted an the stem, at right angles thereto, is a closure pin (23) which extends into the bore (15) of the hub (14) of a mushroom-shaped closure element (10). The surface of the domed head of the closure element is in contact with an O-ring seal (51) at one of the OUT ports. When the rotor (20) is turned, the O-ring (51), in contact with the surface of the domed head (12), cams the closure element (10) inwardly causing the element to slide inwardly on the closure pin (23). 
     When the closure element (10) is in place to close-off one of the OUT ports, the other OUT port is opened and the pressure off the water flowing through the valve exerts a direct pressure on the flat annular undersurface (59) of the head of the closure element thereby maintaining the closure element in tight contact with the O-ring seal (51).

Abstract: A PLL system having a variable oscillator (86) and apparatus for generating both phase and frequency error signals for controlling the variable oscillator, includes apparatus, responsive to the polarity of the frequency error signal. The PLL input signal is sampled and digitized by said VCO output signal. The phase and frequency error signals are derived from accumulated input signal samples. The polarity bit of the accumulated samples is used to selectively disconnect the frequency error signal from the variable oscillator when the PLL system essentially attains frequency lock thus precluding noise in said frequency error signal from causing jitter in the phase of the oscillator output signal. The input signal may be an analog video composite signal and the VCO frequency is synchronised to a multiple of the burst frequency.
