Abstract: An ultra-low distortion electronic amplifier wherein the global dominant pole is formed by the selection of circuit and component arrangement within the input stage, such that the global dominant pole, is of third order, at audio frequencies. This audio power amplifier implements a high order global dominant pole with the use of operational amplifiers, and this high order dominant pole is distributed across both the voltage amplification stage and input stage without adverse reduction in the slew rate. The amplifier has increased negative feedback at audio and ultrasonic frequencies, giving a reduction in distortion across the entire audio band and some of the lower ultrasonic band.

Abstract: A method and apparatus for a self-checking multi-threaded processor includes a first thread for generating a first I/O request; a second thread for generating a second I/O request; and a self-checking component for comparing the first I/O request and second I/O request. Processor operation is selectively suspended based on the comparison of the first I/O request and the second I/O request. The self-checking multi-threaded processor may include a third thread for generating a third I/O request; the self-checking component may compare the I/O requests of the first thread, the second thread, and the third thread; and processor operation may selectively continue with issuance if at least two the first I/O request, the second I/O request, and the third I/O request match. The second thread may begin processing to generate the second I/O request upon the generation of the first I/O request by the first thread.

Abstract: In performing a predetermined adjustment of the TV set 12, the computer 11 plays a most active part in the television-set adjusting system. The computer 11 sends adjusting parameters necessary for the adjusting process to the TV-set adjusting instrument 13; the TV-set adjusting instrument 13 performs the adjusting process by using the parameters; and the computer 11 gathers the result of executing the adjusting process, and sets the TV set 12. This feature eliminates a manual work in executing the adjusting process. The adjusting process is executed through the computer processing. As a result, the cost for the adjusting process is reduced and the adjusting process is executed at high speed.

Abstract: A video projector includes a cabinet, and adjusters provided in bottom and top surfaces of the cabinet and located on left and right positions of the bottom and top surfaces close to the front surface of the cabinet. The adjusters are supported by shafts perpendicular to the front surface so as to be rotatable in an angular range of 90°. When the adjusters are postured to be perpendicular to bottom and top surfaces of the cabinet, the cabinet is placed horizontally. When the adjusters are postured to be perpendicular to left and right side surfaces of the cabinet, the cabinet is placed vertically. Since a horizontal/vertical placement change-over switch is operated in accordance with the horizontal/vertical placement of the cabinet, a video image can be projected correctly onto a screen regardless of the horizontal/vertical placement of the cabinet.

Abstract: A source synchronous interface determines an amount of delay for an incoming data signal and a phase offset for a latch device that latches the incoming data signal. A delay locked loop may be a dual loop delay locked loop, in which case, the loops may use a low jitter, local clock signal and an input clock signal that was transmitted with the data signal. The low jitter, local clock signal may provide a stable source from which to derive good clock signal edge transitions. The input clock signal may be used to determine the long term clock signal drift. A finite state machine within the dual loop delay locked loop may provide the necessary information for the amount of delay and the phase offset. The delay of the incoming data signal is produced by a digital delay line.

Abstract: A reciprocating piston engine (2) includes an exhaust system comprising an exhaust pipe (8) which communicates with a silencer (10), whose upstream portion (11) is divergent in the direction of gas flow through it, an oxidising catalyst (12) and an air supply pipe (14) communicating with the exhaust pipe at a position upstream of the catalyst and silencer. The air supply pipe (14) includes a Reed valve (16) which is adapted to open under a pressure differential to permit air to flow into the exhaust pipe. In order to maximise the air flow into the exhaust pipe the effect of pressure pulses within the exhaust pipe is utilised and for this purpose 3L2−(2L1+L2) is equal to ±0.25 to 0.

Abstract: A calibration and adjustment system for post-fabrication control of a delay locked loop charge pump current is provided. The calibration and adjustment system includes an adjustment device that varies an amount of charge pump current. Such control of the charge pump current in a delay locked loop allows a designer to achieve a desired delay locked loop operating characteristic after the delay locked loop has been fabricated. A representative value of the amount of adjustment desired in the charge pump current may be stored and subsequently read to adjust the delay locked loop.

A flat-plate-like noise filter having electromagnetic wave absorbing material is arranged between the first component and the short-circuit element, so as to allow the male electrical connector element to extend through it and surround the male electrical connector element. This can provide the squib connector assembly that can adequately meet the demand for miniaturization and space saving.

Abstract: A tape loading apparatus having a first swinging arm. When a loading pin of the first swinging arm is elastically pressed against a positioning stopper at a loading position by an elastic force of a spring member, a joint portion of the first swinging arm maintains bent attitude having an angle smaller than 180° and no-tooth portion of a loading gear is in contact with a no-tooth portion of a mode gear. Even in case where a reactive force of the spring member causes the loading gear to generate a rotation force, the rotation force is received by a shaft member supporting the mode gear.

The negative impedance device is highly responsive to high to low and low to high transitions on the signal, and when one of these types of transitions begins to occur on the signal, the negative impedance device senses the transition and quickly drives the signal to the intended value before a point in time when the signal would have reached the intended value had the negative impedance device not been used. Further, a signal transition accelerator design that reduces signal rise and fall times is provided. Further, a method for accelerating a signal transition is provided.
