Abstract: A water supply control apparatus includes a flushing device (1) to be supplied with water, a water supply valve (4) for controlling the supply of water to the flushing device, a driving signal generator for selectively generating driving signals of first and second periods, respectively, a sensor (31,33) responsive to one, at a time, of the driving signals for detecting whether there is a user of the flushing device at one of the first and second periods, to produce a sensor signal selectively including a user-present signal and a user-absent signal of said one period, and a control circuit (2) responsive to the sensor signal for controlling the water supply valve (4). The control circuit includes a first control section having a switching element responsive to the user-absent signal for issuing a first switching signal to the driving signal generator to generate the driving signal of the first period and responsive to the user-present signal for issuing a second switching signal to the driving signal generator to generate the driving signal of the second period and an output element responsive to the sensor signal for issuing a water supply valve control signal, a second control section responsive to the water supply valve control signal for controlling the water supply valve, and a battery (5) as a power supply for operating the water supply valve, the driving signal generator, the sensor, and the first and second control sections. The second period is shorter than the first period.

Abstract: Disclosed is a process of growing a conformal and etch-resistant silicon dioxide on a surface by forming a conformal layer of polysilicon and subjecting the polysilicon to thermal oxidation to completely convert the polysilicon into (poly) silicon oxide. 
     Disclosed also is a method of forming an isolation trench in a semiconductor substrate having a high integrity oxide sidewall. After forming the trench (58) in the substrate surface using a suitable etch mask and RIE, a single (thermal) oxide or dual (thermal) oxide and (CVD) nitride liner (64) is formed on all trench surfaces. A conformal layer of undoped polysilicon (66) is then formed (by. e.g. LPCVD) on the liner. By subjecting to thermal oxidation, the polysilicon is completely converted into a conformal (poly) silicon oxide layer (68) having a thickness about 2.5 times that of the polysilicon layer. The resulting (poly) silicon oxide has the conformality of CVD oxide and the high etch resistance of thermally grown oxide. 
     Alternatively, prior to forming the (poly) silicon oxide, the polysilicon layer is removed from the trench floor and the substrate surface in order to limit volume expansion of the polysilicon to a single direction perpendicular to the trench walls. 
     The trench is filled with oxide, epitaxial silicon, polysilicon, polymers or metal, as desired. For achieving substrate contact through the trench, the trench bottom is opened up by RIE. Polysilicon is deposited with in-situ doping at a high temperature to fill the trench and simultaneously diffuse the dopant from the polysilicon fill into the underlying substrate to form a channel stop.

Abstract: A calibrated automatic test system includes a test station for generating digital test function codes and a test head containing a plurality of I/O pins for connection to a device under test. Each I/O pin includes a pin electronics circuit responsive to the digital test function codes for providing test signals to the device under test. The pin electronics circuits are inexpensive CMOS IC's and lack the accuracy needed to test VLSI devices at the frequencies of interest. An external calibration unit is connected to each I/O pin and data measurements are taken which represent the performance of the CMOS IC's. The data measurements are converted to calibrated function codes representing desired data values which are then stored in correction memory circuits which respond to nominal digital test function codes and substitute in their places cali­brated function codes which are then supplied to the pin electronics circuits.

Abstract: The condensation products are prepared by esterifying carboxylic acid of the formula RCOOH with a hydroxyalkanesulphonate salt of the formula HO-(CH2)n-SO3X, where n can assume values from 2 to 4 and X denotes an alkali metal or NH4, in the presence of consistency regulators, esters of carboxylic acids having 3-36 carbon atoms with alcohols having 3 to 30 carbon atoms being used as consistency regulators. Suitable esters are those such as isopropyl stearate, cetyl stearate and corresponding palmitates; fatty acid esters of glycerol and other polyhydric alcohols can also be employed. Esters of dicarboxylic acids are also suitable. The consistency regulators favourably regulate the course of the process and permit, inter alia, a better removal of excess carboxylic acid by distillation. The consistency regulators can remain in the final product, as they are useful ingredients.

Abstract: The known methods for homogenising the field distribution in a cooking space heated by microwaves, such as rotating antennas, rotating plates and wave stirrers, are relatively expensive. The characteristic impedance is periodically changed by means of a rotating element (5) arranged in the waveguide (3) between the magnetron (1) and the injection aperture (6) into the cooking space (2). In this way, the output frequency of the magnetron is also changed, resulting in homogenisation of the field. <IMAGE>

Abstract: A process for treating a flue gas containing sulfur dioxide and fly ash is disclosed in which an aqueous absorbent liquid is sprayed into the glue gas stream, and the resulting gas is fed to a vertical, open-ended pipe to form a jet annular stream, so that portions of the SO₂ and the fly ash contained in the flue gas are transferred to the liquid phase. The jet annular stream is then sparged into the aqueous absorbent held in a well-mixed vessel to form a jet bubbling layer in a shallow, upper region of the aqueous absorbent, so that a greater part of the SO₂ and the fly ash are removed from the gas. Air is introduced into a deep lower region of said aqueous absorbent to provide streams of fine oxygen-containing gas bubbles throughout the whole vessel, so that the absorbed SO₂ and other sulfites are oxidized to form coarse gypsum crystals while COD of the absorbent is reduced.

Abstract: This invention relates to a face-down connecting method of an electrode (2) formed on a semiconductor device (1) surface and an electrode (4) on a circuit substrate (3) by using an insulating resin, in which after positioning the electrode of the circuit substrate and the electrode of the semiconductor device, the both are pressed from the side of semiconductor device or circuit substrate, and, in this state, a light-stiffening insulating resin (6) is dropped on the side surface of the semiconductor device, and then the light-stiffening insulating resin (6) is stiffened. According to the method of this invention, since the light-stiffening insulating resin is dropped and injected between the semiconductor device and circuit substrate with the electrodes of the semiconductor device and circuit substrate pressed to each other, the light-stiffening insulating resin intervenes between the two electrodes, and the problems of failure of electric contact between the two electrodes or high connection resistance will be avoided. Besides, since the electrodes of the semiconductor device and circuit substrate are positioned before injecting the resin, it is possible to dentify the electrodes more easily than when positioning after dropping the resin, so that positioning of higher precision may be done in a shorter time.
