Patent EP-0607936-A1 (EP)
Inventor: METZGER ROBERT A
IPC: H01L29/205
Filed: 1994-01-19
Abstract: An electrical junction is precisely located between a highly p doped semiconductor material (26) and a more lightly n doped semiconductor material (30) by providing a lightly p doped buffer region (28) between the two materials (26, 30) with a doping level on the order of the n doped material's. The buffer region (28) is made wide enough to establish an electrical junction at approximately its interface with the n doped material (30), despite a diffusion of dopant from the p doped material (26). When applied to a heterojunction bipolar transistor (HBT), the transistor's base serves as the heavily p doped material (26) and its emitter as the more lightly n doped material (30). The buffer region (28) is preferably employed in conjunction with a graded superlattice (46), located between the buffer (28) and the emitter (30), which inhibits dopant diffusion from the base (26) to the emitter (30). A p-n junction is formed within the superlattice (46), which functions on one side as an electrical extension of the emitter (30) and on the other side as an electrical extension of the buffer (28), and establishes the electrical junction of the p-n junction location. The precise positioning of the electrical junction results in a known and repeatable emitter-base turn-on voltage.

Abstract: A hybrid excitation type permanent magnet synchronous motor is provided with an armature (1) and a rotor core (12) arranged to be rotated relative to the armature (1). Permanent magnets are installed to the rotor core (12) and generates magnetic flux which passes through the armature (1) through a gap between the rotor and armature. Salient pole portions are integral with the rotor core and not covered with the permanent magnets. The salient pole portions (12a) are arranged opposite to the armature (1) through gap such that the magnetic flux by the permanent magnets is effected by the magnetic flux passing through the salient pole portions. A direct current excitation coil (5) generates the magnetic flux passing through the salient pole portions (12a). Therefore, an operable speed area of the motor is increased without using the demagnetization control and without degrading the efficiency. Also a damper coil (17, see fig. 13) may be installed to the salient pole portions (12a). Another embodiment (see fig. 26) comprises a rotor with permanet magnets (13) attached on the whole surface of the rotor. The different poles and salient pole portions interlock (see fig. 28). A further embodiment (see fig. 33) is made like a pancake.

Abstract: Device and method for sleeving an inside surface (40) of a tube (30), which tube may be a heat transfer tube of the kind typically found in nuclear steam generators. The device comprises a sleeve (230) having a wall (310) forming a compact spiral-shaped transverse cross section defining a first position of the sleeve. The wall in its first position surrounds an expandable bladder (240) supported by a support body (360). The support body, bladder and sleeve are inserted into the tube and translated along the inside surface thereof to the region of the tube to be sleeved. The compact spiral-shape of the wall in its first position allows it to pass unimpeded through the inside diameter of a previously installed sleeve that may be disposed in the tube, so that the previously installed sleeve does not interfere with the translation of the sleeve along the inside surface of the tube. Connected to the bladder is a pressurizer (250) for pressurizing the bladder so that the bladder expands to expand the wall of the sleeve (after it passes through the inside diameter of the previously installed sleeve) from the first position to a second position wherein the wall forms an annular transverse cross section. A fluid reservoir (260) is in fluid communication with the pressurizer for supplying fluid to the pressurizer which in turn pressurizes the fluid and supplies the pressurized fluid to the bladder to pressurize and expand the bladder. As the bladder expands, the wall moves from its first position to its second position and intimately engages the inside surface of the tube for sleeving the tube.

Abstract: Described are a process for soldering at least one component having solder bumps (12) to a substrate and a process for forming solder bumps (12) on metal pads (13) of an element, such as an IC package (10) or substrate (11) or both. The bumps (12) are formed by stencil printing solder paste deposits (21) on the metal pads (13), heating the solder paste deposits (21) to reflow temperature of the solder in the solder paste deposits (21), and allowing the molten solder in each deposit to coalesce and during subsequent cooling solidify forming the bumps (12) on the metal pads. The bumps are formed by conducting the stencil printing through apertures (20) in an ultra-thick stencil (19), the apertures (20) having trapezoidal crossection in the plane normal to the broad surfaces of the stencil with the top opening being smaller than the bottom opening and with the walls of the aperture sloping at an angle within a range of from 1 to 45 degrees from the vertical, the solder paste having a low tackiness and high metal loading, and the solder paste deposits (21) covering an area which is equal to or exceeds an area of the metal pad (13) in any ratio between 1.5:1 and 5:1. Bumps formed in this manner lead to the formation of reliable solder joints.

Abstract: A method of detecting a deflated tyre on a vehicle by comparing the rolling radii of the tyres by means of comparing angular velocity speed signals C1, C2, C3 and C4 from wheel speed sensors one at the left-hand front, right-hand front, left-hand rear and right-hand rear wheel positions respectively, comprising the step of calculating in normal driving an error value (DEL') where       DEL' =        [(C1+C4)/2-(C2+C3)/2] x 100       (C1 + C2 + C3 + C4)/4        ,           
 the step of determining a correction factor (LAT), by calculating from the four angular velocity values C1, C2, C3 and C4 respective first, second, third and fourth deciding factors (MC1, MC2, MC3, MC4) where 
MC1 = C1 
MC2 = C2/[(C2+C4)/(C1+C3)] 
MC3 = C3/[(C3+C4)/(C1+C2)] 
MC4 = C4/[[(C2+C4)/(C1+C3)] x [(C3+C4)/(C1+C2)]], 
then summing the four deciding factors and multiplying this sum by a centralising constant (K) to give a central deciding factor (MPSD) and selecting the correction factor (LAT) as follows, if the first or second deciding factor (MC1 or MC2) is greater than the central deciding factor (MPSD) then       LAT = 2 x (C3 - C4) x (C1 + C2 + C3 +C4),           
 if the third or fourth deciding factor (MC3 or MC4) is greater than the central deciding factor (MPSD) then       LAT = 2 x (C1 - C2) x (C1 + C2 + C3 + C4),           
 or if none of the deciding factors (MC1, MC2, MC3 or MC4) is greater than the central deciding factor (MPSD) then       LAT = (C1 + C3 - C2 - C4) x (C1 + C2 + C3 + C4),           
 the step of calculating a corrected error value (DEL), and the step of operating a tyre warning indicator provided in the vehicle to indicate that at least one tyre is deflated when it is sensed that the magnitude of the corrected error value (DEL) is in the range 0.05 to 0.5, characterised by the step of determining vehicle related constants A, B, C for clockwise cornering and E, F G for anti-clockwise cornering by a setup procedure from sets of values (SV1-SVn n = 2,3,4...) of C1-C4 obtained by driving the vehicle respectively clockwise and anti-clockwise with its four tyres inflated to their normal scheduled pressure around a circle at a plurality of n constant speeds, and then calculating the corrected error value (DEL) by DEL = DEL' - DELCOR where DELCOR = 
(E x LAT)+(F x LAT²)+(G x LAT³) if the sign of the correction factor LAT is negative 
or DELCOR = 
(A x LAT)+(B x LAT²)+(C x LAT³) if the sign of the correction factor LAT is positive.
