A lightweight bumper structure is achieved without a reduction in the amount of absorption of collision energy. A bumper structure (B1) is provided with a left and right pair of bumper stays (1, 1) fixed to side members (S), and also with a bumper reinforcing member (2) supported by both the bumper stays (1, 1). Each bumper stay (1) is formed in a shape the width of which gradually increases from the side member (S) toward the bumper reinforcing member (2). The bumper reinforcing member (2) is curved between both the bumper stays (1, 1). The rigidity of the bumper stays (1) and the bumper reinforcing member (2) is set so that the bumper stays (1) are crushed in the front-rear direction after the curved portion of the bumper reinforcing member (2) is rectilinearly extended.

A heterodyne communication system uses coherent data modulation that is resistant to phase noise. In particular, a pilot tone and reference clock signal are transmitted along with the modulated data to form the basis of an electrical demodulation local oscillator at the receiver. The pilot tone and/or reference clock signal carry phase noise which is correlated with the phase noise in the data signal. At the receiver, the local oscillator is generated from the pilot tone and reference clock signal in a manner so that the local oscillator also has phase noise which is correlated with the phase noise in the data signal. Thus, the two noise components can be used to cancel each other during demodulation of the data signal using the local oscillator.

摘要:
A confined pulsed laser deposition method and apparatus that includes an ablative coating between a transparent confinement layer and a backing plane, and a laser beam directed through the confinement layer to ablate the coating at generally ambient temperature and pressure, and using laser induced pressure to synthesize metaphase from the ablative coating. For example, diamond phase carbon can be synthesized from a graphite coating. The laser beam can be directed through a focus lens to control the final spot size, or through a beam diffuser to make the intensity more uniform. An XYZ-stage can position a desired target area of the ablative coating to be irradiated by the laser beam. The laser beam can have an intensity of less than about 6 GW/cm2, or less than about 4 GW/cm2. The laser beam can have an excitation wavelength of about 568 nm.

摘要:
A heat dissipating device includes a flat evaporator, a vapor pipe, a liquid pipe, and a condenser. The flat evaporator consists of a bottom plate, a porous material, and a top lid. The porous material is located on the bottom plate and provided with vapor flow passages. The vapor pipe and liquid pipe are communicably connected at respective one end to a vapor port and a liquid port on the evaporator, and at the other end to two sides of the condenser. The evaporator has simple structure and low manufacturing cost, and can fully effectively bear on an electronic chip to enable reduced room needed for installing the evaporator and reduced thermal resistance during heat dissipation. The heat dissipating device can be used to dissipate heat produced by computer chips, and to cool LED illuminating devices, chips for communication devices, high-power heat-producing elements in military, medical, aerial, and aerospace apparatuses.

摘要:
A transmitter subsystem generates an optical signal which contains multiple subbands of information. The subbands have different polarizations. For example, in one approach, two or more optical transmitters generate optical signals which have different polarizations. An optical combiner optically combines the optical signals into a composite optical signal for transmission across an optical fiber. In another approach, a single optical transmitter generates an optical signal with multiple subbands. The polarization of the subbands is varied, for example by using a birefringent crystal. In another aspect of the invention, each optical transmitter generates an optical signal containing both a lower optical sideband and an upper optical sideband (i.e., a double sideband optical signal). An optical filter selects the upper optical sideband of one optical signal and the lower optical sideband of another optical signal to produce a composite optical signal.
