摘要： An endbell assembly operatively associated with a laser body includes a metal endbell component sealed to a crystalline endbell component which terminates with a crystalline optical component. The crystalline endbell and crystalline optical component are hermetically sealed without using a frit. This is achieved by polishing and a modified optical contacting technique whereby the optical component and crystalline endbell component are polished to a flatness of about 1/2 wavelength of light, placed in a contacting position and then thermally cycled at a temperature of about 400.degree.-500.degree. C. for about 1 to 10 hours, forming a substantially uniform unitary body. This seal is mechanically strong and minimizes the introduction of contaminants into the endbell assembly. In one embodiment, the crystalline endbell component is metallized and braze-sealed to the metal endbell component. In another embodiment, the two endbell components are hermetically sealed by modified optical contact and thermal cycling.

摘要： An improved digital signal line carrier type detector non-conductively senses and counts voltage pulses on a probed line. Further, the detector produces a human-readable display of the carrier type in use on the probed line, and can detect carriers of various frequencies without the use of multiple oscillators or probes. The detector may be housed in a hand-held portable housing, and may be powered by one or more batteries. A timer circuit is usable with the detector to prevent accidental discharge of the battery for an extended period of time.

摘要： A method of monitoring evaporative emissions of a vehicle includes the steps of establishing a baseline pressure within a vehicle evaporative emission system during the occurrence of a vehicle-off condition, detecting a change in the baseline pressure during the vehicle-off condition, and indicating whether the change in the baseline pressure is within a desirable limit.

摘要： A fuel weathering method for an evaporative emission system of a motor vehicle includes determining a current temperature of liquid fuel inside the evaporative emission system, determining a fuel residency time representing the amount of time the fuel has resided above the current temperature, and performing a system diagnostic test of the evaporative emission system only if the fuel residency time exceeds a minimum fuel residency time.
