摘要： A method of forming a hollow structure having a predetermined shape from a sheet of superplastic material. The sheet is initially formed into a preform configuration (10). A reusable fluid inlet tube is placed in the preform configuration (10) to define a port in fluid communication with the interior portion of the preform configuration (10). The preform configuration (10) is disposed in a containment die, which defines a cavity having the predetermined desired shape. Force is applied to the containment die to temporarily seal the edges of the preform configuration without the use of welding or diffusion bonding. Once its edges are sealed, the preform configuration becomes a gas-tight envelope capable of holding fluid that is introduced through the fluid inlet tube. Fluid is fed through the tube to apply internal pressure to the gas-tight preform configuration under superplastic conditions while it is still being held in the containment die.

摘要： Temperature sensor (10), with programmable offset, generates an output voltage (Vo) that is a PTAT voltage VPTAT shifted by offset voltage Voff. Band gap cell (12) generates a basic voltage across first resistor (RPTAT) to produce current (IPTAT). Second resistor (Rgain), connected between first resistor (RPTAT) and reference voltage terminal (Vee), provides voltage gain. Third resistor (Roff) is connected across the base-emitter junction of transistor (Q1) and between second resistor (Rgain) and output terminal (20) where voltage (Vo) is provided. The transistor's base-emitter voltage provides a portion of Voff. Third resistor (Roff) reduces the portion of current (IPTAT) flowing through second resistor (Rgain) to provide the remaining portion of Voff. Current source (IS1) supplies an emitter current and a current for third resistor (Roff). Offset voltage Voff is set by trimming third resistor (Roff) until voltage (Vo) equals a voltage applied to reference voltage terminal (Vee) at a lower end of a desired temperature range. The gain of VPTAT is then set by trimming first resistor (RPTAT).

摘要： A system for simultaneously detecting imperfections of both sides of a dual sided compact disc (1) includes a self-centering chuck (7) for retaining the compact disc (1) and rotating it beneath two illumination sources (9) and dual video cameras (15) or other devices for receiving light from the illumination source (9) that reflects from the surface (17) under study. The cameras (15) are oriented to receive illumination reflected only from an imperfectly flat portion of the surfaces (17) being inspected. A stepping motor (19) is used to turn the compact disc (1) through a number of positions during at least one complete revolution while it is exposed to the light sources (9). The signals received in the video cameras (15) are then processed by a template algorithm to compare the light level received with that from an assumed flat portion of the disc.

摘要： To obtain a secondary battery simultaneously having performances such as extremely large electric capacity, excellent discharge efficiency, high voltage, and freedom from fire in high temperature environments. The secondary battery of the invention comprises a positive electrode having lithium cobalt oxide composed of lithium, cobalt and oxygen, a negative electrode capable of intercalating and deintercalating lithium, and an electrolyte contacting with both of the positive electrode and the negative electrode. The lithium cobalt oxide is powder, and this powder has a mean particle size in a range of 5 νm to 25 νm. The lithium cobalt oxide has a chemical composition in which the molar ratio of said cobalt to said lithium is in a range of 0.96 to 1.04, and also has a crystallinity so that the full width of half maximum of 003 diffraction peak in X-ray diffraction using CuKα ray is in a range of 0.15° to 0.18°. The electrolyte is a non-aqueous electrolyte. The potential of the positive electrode in charged state is in a range of 4.2 V to 4.5 V to the redox potential of lithium.

摘要： A signal conditioning circuit (10) compresses an audio signal by producing a gain signal (Vc) that is a function of the time-averaged audio signal and a compression ratio, and amplifying the audio signal by an exponential function of the gain signal. The conditioning circuit merges the functions of buffering the audio signal and producing a full-wave rectified version of the audio signal into a single buffer circuit (12). An averaging circuit (14) generates a time-averaged signal in response to the full-wave rectified signal. An interface circuit (16) includes downward expansion (60), compression (58) and limiting (59) circuits for scaling the time-averaged signal with a low compression ratio when it is less than a break point, with a selected compression ratio when it is between the break point and a rotation point, and with a high compression ratio when it exceeds the rotation point.

摘要： Rail-to-rail amplifier (10) has a low complexity output stage (18) that provides a high ratio of load current (IL) to no load idle current. Included are first and second output transistors (Q1, Q2) whose current circuits are connected in series at the output terminal (20) between high and low voltage supplies. Control transistor (Q3) responds to drive voltage (Vd) at its base by modulating the base-emitter voltages of the first output transistor and a gain transistor (Q4) in opposite directions to modulate their respective output and gain currents. Regenerative current source (55) supplies current to the gain transistor by returning the gain current in a regenerative feedback loop (CM1, IS1, 58) to its emitter so that the current source idles at a low gain current but is capable of supplying much higher gain currents. Voltage element (65) responds to the gain current by applying a control voltage to the base of the second output transistor so that the output transistors' output currents are unbalanced thereby generating an output current at the output terminal.

摘要： A system for repeated coding and decoding of digital video signals, whereby the problems of picture quality degradation caused by repeated intra-coding of frames are avoided. The present system ensures that repeated coding/decoding of frames using intra-coding processes, always uses the same frames as the non-interpolated frames, so that at each generation, a significant amount of the original information is present, and not repetitively approximated as in current systems. The invention lies in adding code signals to the decoded video signal, said code signals containing the information on which frames were not interpolated in previous codings, so that on coding said signal again, the same coding will be used and therefore far less information will be lost.

摘要： An apparatus for extracting and injecting liquid coolant from and into a reservoir for an engine cooling system. The apparatus includes a storage tank (110) for the liquid coolant, and an air pressure system (200) for selectively applying fluid pressure to the tank (110) either above or below atmospheric pressure. A hose (340) connects the tank (110) to the engine cooling system reservoir through a double shut-off-type coupling (500). One part (520) of the coupling is connected to the reservoir, and the other (510), to the end of the transfer hose (340), each having its own independent shut-off valve (522, 512). When the coupling (500) is connected, the valves (512, 522) in both components are opened; conversely, when the coupling (500) is disconnected, the valves (512, 522) automatically close.

摘要： A retro-reflective sign (10) is provided having a front face (12) member attached to a back member (14). The face member (12) has a plurality of cube corners (16) disposed along its back surface. The sign can be of any shape or color and provides superior light reflection at night as compared to conventional signs. Thus, the sign can be easily seen while driving at night. In an alternative embodiment, the cube corners (16) are disposed along the inner surface of the back member. The front face member (12) or the entire sign (10) can be coated with a silicone material (80) to provide added protection to the sign from scratching and vandalism.
