摘要： A method and apparatus for operating a frequency division multiplexing (FDM) transmitter within a common communication channel is disclosed. The carrier frequency for each separate channel is adjusted for minimizing intermodulation interference. The system randomly allocates each separate channel within the available bandwidth to provide an initial set of separate channel allocation and corresponding carrier frequencies. Thereafter carrier to intermodulation ratio (C/IM) on each channel is measured and the worst channel with the lowest carrier to intermodulation ratio (C/IM) is removed. The system then repeatedly inserts a channel in available unoccupied bandwidth to produce the largest minimum carrier to intermodulation ratio (C/IM). The deletion and insertion continues until no improvement in minimum carrier to intermodulation ratio (C/IM) can be achieved for said random allocation of separate channels. The selected set of separate channel allocations is further fine-tuned by deleting the worst channel with minimum carrier to intermodulation ratio (C/IM) and deleting one other channel from said separate channel allocations to provide a particular dual channel deletion. The system then repeatedly inserts two channels in available unoccupied bandwidth which produces the largest minimum carrier to intermodulation ratio (C/IM). The system continues on dual deletion and insertion until no improvement in minimum carrier to intermodulation ratio (C/IM) can be achieved for said random allocation of separate channels. The carrier frequencies are then tuned according to said set of separate channel allocation.

摘要： A hose includes at least an inner-layer tubular member, an intermediate layer, and an outer-layer tubular member. Both the inner-layer tubular member and the outer-layer tubular member are made of plastics. The intermediate layer is formed by wrapping a net. An outer surface of the intermediate layer is provided with a helical structure made of plastics and the outer-layer tubular member encloses the helical structure. The helical structure has a mechanical strength greater than the outer-layer tubular member. Since both the helical structure and the outer-layer tubular member are similarly made of plastics, the bonding strength therebetween can be enhanced. When the hose is subjected to bending, the helical structure helps to prevent the hose from being compressed and deformed, thereby maintaining the inside diameter of the hose to ensure smooth flow of liquid or gas through the hose.
摘要翻译： 软管包括至少内层管状构件，中间层和外层管状构件。 内层管状构件和外层管状构件均由塑料制成。 中间层通过包裹网而形成。 中间层的外表面设置有由塑料制成的螺旋结构，外层管状构件包围螺旋结构。 螺旋结构的机械强度大于外层管状构件。 由于螺旋结构和外层管状构件都类似地由塑料制成，因此可以提高它们之间的结合强度。 当软管经受弯曲时，螺旋结构有助于防止软管被压缩和变形，从而保持软管的内径，以确保液体或气体通过软管的平稳流动。

摘要： A pulse shaping filter for shaping pulses received at a specified data rate is disclosed. The filter has a desired impulse response associated with a plurality of sampled values. The filter includes a sampling circuit responsive to the input pulses, such that each pulse is sampled at a desired sampling rate. A delay circuit provides a plurality of delayed versions of the sampled pulse, wherein said sampled pulse propogate through said delay circuit at a unit delay time substantially equal to the period of the desired sampling rate. A plurality of resistors are coupled to the delay circuit, each resistor providing a weighing coefficient by which the delayed versions of the sampled pulses are multiplied to provide a plurality of weighed delayed pulses. A summing circuit is adapted to add all said weighed delayed pulses to provide shaped pulses. The resistors are selected such that each sum of said weighed delayed pulses as the pulses are propogated through the delay circuit is substantially equal to a corresponding sampled value of said impulse response.

摘要： A task chair, including a backrest assembly and a seat assembly pivotally coupled both to one another and to side portions of a fixed yoke member for synchronized movement, in which the seat of the seat assembly moves upwardly and forwardly concurrently with recline of the backrest of the backrest assembly. The chair further includes a tension assembly including an elongate tension member, such as a leaf spring, secured at one end thereof to the yoke member, and a contact member, such as a contact roller, adjustably mounted to the seat assembly. The contact member engages the tension member such that the tension member resists recline of the backrest assembly and concurrent movement of the seat assembly from their initial positions, and also provides a restoring force which tends to move the backrest to its initial upright position and the seat to its initial rearward and lowered position. The contact member is adjustable with respect to the tension member in order to vary the effective moment arm acting upon the tension member, thereby varying the pre-load of the tension member and the resistance provided by the tension member.

摘要： A method and apparatus is disclosed for automatic elimination of frequency instabilities in a receiver frequency converter. Such instabilities result from temperature variations and mechanical vibrations of the local oscillator of a first stage converter. A marker signal is introduced into the first stage down converter mixer and is subjected to the same variations in frequency conversion as is the received signal from an antenna. Intermediate down converted received signals and an intermediate down converted marker signal are received by a second stage converter where such signals are applied to a mixer, the output of which is free of frequency variations introduced by the local oscillator of the first stage converter.
