Patent EP-0579438-A2 (EP)
Inventor: BRADY MICHAEL FRANCIS
IPC: B23K1/008
Filed: 1993-07-06
Abstract: A solder self-alignment process for aligning a semiconductor chip (13) with, and bonding the chip to, a substrate (12) is preformed in an atmosphere rich in gaseous formic acid, at least during the melting step. It is preferred that the formic acid atmosphere be maintained during the self-alignment step and the step of cooling and hardening the solder elements (23). With this feature, one can completely avoid the use of any solid or liquid fluxes and avoid the consequences of such use. Nonetheless, the molten solder elements (23) dependably bond to the bonding surfaces and vertically align themselves.

Abstract: An aerosol sampler (10) comprises at least one U- tube (16) whose ends are fixed to a support (14), and through which the aerosol is caused to flow. Means (40) are provided to set the tube vibrating, and to measure its resonant frequency. The bend of the U-tube (16) acts as an impactor so aerosol particles larger than a cut-off size are trapped, causing a change in the measured frequency. A sampler (10) may include a number of such U-tubes (16-24) in series, with steadily decreasing cut-off sizes, so the aerosol particulate size distribution can be determined.

Abstract: An electrically-operated fluid valve comprising at least one valve seating (11), a flexible diaphragm (13) covering the valve seating and being uniformly subjected on a lower surface thereof to a fluid pressure, and a closure member (28) pivotably mounted above the flexible diaphragm and rotatable about a pivot axis (29) thereof between first and second positions. An electrical motor (36, 81) is provided for rotating the closure member in a first direction whereby a first end of the closure member (14) depresses the diaphragm on to the valve seating, thereby reducing the pressure on one surface of the diaphragm within an area of the valve seating only, an opposite surface of the diaphragm and an opposite end of the closure member (18) still being subjected to said fluid pressure. The electrical motor rotates in the opposite direction for lifting the diaphragm from the valve seating. Preferably, the electrical motor (81) is controlled by a switching circuit (85) including first and second d.c. supply rails (111, 112) connected across a storage element (125) connected in series with the motor (81). A normally closed switching element (115) is responsive to a voltage across the supply rails rails for opening and allowing current to flow through the motor so as to urge the closure member into the second position whilst substantially fully charging the storage element (125), whereupon decoupling the voltage from across the supply rails causes the switching element (115) to close thereby providing a discharge path through the motor for the storage element which discharges thereby urging the closure member (28) into the first position.

Abstract: The one-piece flat vibratory measuring element (1) has two fastening tongues (3), between which, connected by means of coupling elements (9), the vibrating string (15) is constructed. In the connection region of the vibrating string (15) to the coupling elements (9), node regions (19) are constructed, which consist of elastic tongues (13) running in pairs parallel to the vibrating string (15), the roots of the said tongues and the attachment points of the vibrating string (15) lying on a straight line. The mass per unit length of the elastic tongues (13) is significantly larger than that of the measuring string (15). If the measuring string (15) oscillates in the direction (A) of the small bending stiffness, the elastic tongues (13), arranged in pairs, also oscillate at the same frequency, but in opposite phase. These opposite-phase oscillations effect an extensive suppression of oscillations in the node region (19) and in the coupling elements (9) lying behind it. By means of this decoupling of the oscillations of the vibrating string (15), a very low loss of oscillation energy occurs. The vibratory measuring instrument (1) according to the invention is preferably produced from the finest sheet metal and can be used irrespective of position, thanks to its low mass. <IMAGE>

Abstract: The present invention provides a method and apparatus for an adaptive texture mapping controller which provides a way for computer graphics system users or other functions in a graphical display system, to trade off object image rendering speed for object image texture quality. This trade-off is accomplished by providing a plurality of control signals to the adaptive texture mapping controller which indicate the level of texture quality that the user or other function desires. Upon recognizing these control signals, the adaptive texture mapping controller selects a computation method to be used in generating pixel values necessary to provide the desired level of image texture quality. 
     The adaptive texture mapping controller is able to determine an appropriate method for calculating the end points of span sections of scan lines to be used for the display, based upon a function of the knot parameters which correspond to the vertices which describe each edge of a polygon section of the projected object and one or more of the control signals provided, and then to determine an appropriate interpolation method for calculating the pixel values for pixels on each span chosen, based on a function of the span end points and one or more of the control signals provided. These functions of the distance between knot parameters on a polygon edge or the distance between end points of a span can be mathematical functions of pairs of knot parameters or pairs of end points respectively. 
     The adaptive texture mapping controller is able to determine an appropriate computation method for a given one of a plurality of hierarchical levels of image parameter calculation, where a set of control signals is supplied for each level.

Abstract: A transmission control system for a vehicle having an engine with an output shaft, a torque converter, a stepped automatic transmission mechanism, and a clutch for engaging and releasing a plurality of gear shafts and input/output shafts with each other so as to change a shift change ratio by operation of the clutch. The control system produces a shift signal output indicating a shift change ratio of the stepped automatic transmission mechanism, detects an input torque of the stepped automatic transmission, recognizes an actual mechanical shift start timing of the stepped automatic transmission mechanism and changes engaging pressure on the clutch in accordance with a manipulation variable. An input torque-manipulation variable relationship between the input torque and the manipulation variable for every shift change ratio indicated by every shift signal and every mode of shift change ratios is stored. A manipulation variable calculation is performed when the shift signal and the shift signal output changes and the actual mechanical shift start timing is recognized.

Abstract: An automatic inclination corrector and an inclination sensor using the automatic inclination corrector free from the temperature, for optical instruments. A transparent container 3 seals silicon oil C having a free liquid surface C1. A collimation lens 2 guides the laser beam from the diode 1 to the free liquid surface C1. The inclination corrector corrects the tilt of the instrument to guide the laser beam L4 from the container 3 to advance the beam upward with a normal angle. A reflecting mirror 5 reflects beam L2 after total reflection at the free liquid surface C1. The beam is inverted by a roof prism 6 and passes through silicon oil C and the free liquid surface C1 once. This removes the refractive index n influence to the laser beam L4, and gives an angular change to the laser beam 4 to head the laser beam L4 to a fixed direction.
