A journal bearing has a lining of bearing metal applied to a steel backing. The surface of the lining is laser peen hardened to locally increase the hardness and the seizure resistance of the lining. The underlying core of the lining is unaffected and maintains good conformability of the lining. The overall lining thus possesses both good seizure resistance and conformability.

In man, autonomic and cortical resonances of the nervous system can be excited by inducing subliminal heat pulses in the skin by means of a resistive heat patch, laser, heat lamp, or microwave radiation, or through a slow air jet that carries a small periodic fluctuation in temperature. Deeply subliminal skin temperature oscillations of frequency near 1/2 Hz induced in a subject by any of these means cause sleepiness, drowziness, relaxation, a tonic smile, ptosis of the eyelids, a tense feeling, sudden loose stool, or sexual excitement, depending on the precise pulse frequency used. For certain higher frequencies, the induced subliminal skin temperature oscillations cause fractured thought and a slowing of certain cortical processes. The method and apparatus can be used by the general public as an aid to relaxation, sleep, or arousal, and clinically for the control and perhaps treatment of tremors, seizures, and emotional disorders. There is further application in the form of nonlethal weapons, involving a pulsed infrared laser or a pulsed microwave beam, tuned to a sensory resonance pulse frequency.

Thermal excitation of sensory resonances

Aspects of the invention include a semiconductor device that enables both solder-outflow prevention and inhibition of seizures coming from laser processing residues. A semiconductor device can include a semiconductor chip, a plurality of insulating substrates on each of which the semiconductor chip is fixed, a heat sink having a plurality of first grooves surrounding each one of more than one predetermined arrangement area. The plurality of insulating substrates can be arranged at each of the predetermined areas, and a plurality of second grooves surrounding the first groove, wherein the second grooves are shallower in depth than each of the first grooves, and solder filled between the insulating substrate and the arrangement area on the heat sink.
