Abstract: Object:   
To eliminate inconveniences arising from the porosity of a SIPOS film or the loose bonding of oxygen and Si atoms when a field plate comprising a SIPOS film (11) is sandwiched by oxide films (13; 14) to reduce stress of the field plate. 
       Constitution:   
When the surface layer is thermally oxidized to form an oxide film (14) as a top layer after a SIPOS film (11) is formed, the SIPOS film will be dense and its film quality will be uniform. To prevent this thermal oxidization process from affecting the depth of an impurity diffusion layer and a gate oxide film, a SIPOS film and both oxide films are formed immediately after a field oxide film is formed. After this process, an impurity diffusion layer and a gate oxide film are formed.

Abstract: A target is irradiated with a laser beam having an energy of hν/n, where n is an integer, instead of the photon energy hν required for a reaction to proceed using a conventional single-photon excitation method. A desired reaction is selectively induced by the absorption of multiple photons instead of single photons. It is thus possible to induce a photoreaction in which an absorption is carried out in accordance with a selection theory different from that of single-photon absorption, and which is quite different from a photoreaction induced by a single-photon excitation. Namely, a target or reactant is irradiated with a photon energy hν₂ having a wavelength integral times longer than that of the photon energy hν₁ necessary for a photoreaction to proceed. Photon energy hν₂ is either used in place of the photon energy hν₁ necessary for a photoreaction, or together with the photon energy hν₁, to thereby make the reactant absorb the energy equal to the photon energy hν₁. The method is capable of selectively and preferentially inducing a specific photoreaction among various possible, concurrent photoreactions.

Abstract: An electric rotating machine and manufacturing method of the same is provided that can securely press-fit magnetic poles against an inner circumference of a yoke with a cylindrical body. By directly contacting a first and second end portions (4a and 4b) of the cylindrical body (4) and moving the same relatively, the diameter of the cylindrical body (4) widens in the outer radial direction to press-fit the magnetic poles (3) against the inner circumference of the yoke (2). Thus, the variation of the inner diameter of the magnetic poles (3) that occurs due to the dimensional error in permanent magnet thickness and inner diameter of the yoke (2) is absorbed by the relative movement of the first and second end portions (4a and 4b). This stabilizes the fixing force of the magnet, and allows the magnet to be securely fixed to the yoke (2) without excessive stress on the cylindrical body (4). Furthermore, the displacement of the magnetic poles (3) can be restricted by bending axial ends (4c) of the cylindrical body radially outwardly.

Abstract: An electronic watthour meter is digitally configurable to operate as several different types of watthour meters for metering electrical energy from a variety of different electric utility services. Automatic scaling of line input currents is provided to scale the voltage input to an analog to digital converter over selected ranges such that low level and high level input signals are measured in an optimum range. A digital signal processor is employed to calculate values for metered electrical energy and output pulses, each proportional to a quantum of energy flowing in the circuit being metered. The processor calculates the value of DC offset errors inherent in the various analog circuits of the meter and uses that value in the calculation of metered electrical energy to compensate for such offset errors. The meter employs automatic and manually initiated test functions for testing the operation of the processor and other critical circuits in the meter.

Abstract: The invention provides a method for making an intravascular stent by applying to the body of a stent a solution which comprises a solvent, a polymer dissolved in the solvent and a therapeutic substance dispersed in the solvent and then evaporating the solvent. The inclusion of a polymer in intimate contact with a drug on the stent allows the drug to be retained on the stent during expansion of the stent and also controls the administration of drug following implantation. The adhesion of the coating and the rate at which the drug is delivered can be controlled by the selection of an appropriate bioabsorbable or biostable polymer and the ratio of drug to polymer in the solution. By this method, drugs such as dexamethasone can be applied to a stent, retained on a stent during expansion of the stent and elute at a controlled rate.

Abstract: The invention provides a method of operating a two-coil solenoid valve of the type comprising an armature member located in a housing for movement between a first electromagnet (11) and a second electromagnet (15), each electromagnet being located adjacent to a respective end of said armature member (10) and being switchable between an on state and an off state. In order to move the armature member from a first position closely adjacent to the first electromagnet to a second position closely adjacent to the second electromagnet, the electromagnets are controlled to be at the same initial switched state and subsequently one of said electromagnets is switched to said other switched state for a first predetermined period sufficient to allow the resultant pull exerted on the armature member to be such that the armature member is caused to move towards the second electromagnet. The duration of the first predetermined period is such that said one electromagnet is switched back to its initial switched state before the armature member reaches said second position.

Abstract: An airborne particulate sampling monitor for collecting particulate in either a solid, liquid or gaseous state. The monitor includes at least two intakes (18, 1) each of which accepts airborne particulate. Paired with and coupled to each intake is an appropriate particulate filter (20) for sampling accepted airborne particulate. A vacuum pump (28) establishes air flow into one of the intakes and a sampling process controller (24), coupled between each intake and filter pairing and to the vacuum pump, controls the vacuum pump's establishing of air flow into a selected particulate intake. Preferably, the vacuum pump and sampling process controller reside within a hub unit to which multiple satellite units (14) can be coupled such that each satellite unit employs the vacuum pump and sampling process controller of the hub unit. Due to central processing, conditional sampling at one or more of the units is possible. Further details and manual particulate sampling methods are presented.

Abstract: A method and apparatus for sputter depositing aluminum onto a semiconductor substrate (19) to fill micron and submicron vias utilizes ultrasonic energy to ensure adequate filling of the vias. The semiconductor is supported on a block (16) and heated and subjected to ultrasonic energy greater than 25kHz as aluminum is sputter deposited onto the substrate surface (19). The frequency of the ultrasonic energy is varied from 35 to 42kHz as the aluminum is deposited in order to avoid standing wave or node formation along the substrate surface. This permits an efficient high quality application of aluminum and filling of vias on a semiconductor substrate.
