摘要： An emergency braking system of a chain saw including a hand guard located in front of a front handle bar, and an inertia trigger. The hand guard is pivotally supported by a body of the chain saw and urged by the biasing force of a spring to move downwardly so that its lower end is located in spaced juxtaposed relation to a lever of an actuation device. The inertia trigger is pivotally supported at one end thereof by the hand guard and biased so as to thereby prevent the hand guard from moving downwardly.

摘要： An optical pumping laser system is provided with a resonator suitable for a continuous oscillation having a relatively low gain. The laser system comprises an optical plate such as an etalon plate functioning as a Brewster plate with respect to a pumping beam and also functioning as a reflection mirror with respect to an oscillation laser beam, and a total reflection mirror spaced apart from the optical element so as to define a laser amplification region. The laser system further comprises an output mirror arranged relative to the optical plate to output the oscillation laser beam separated from the pumping beam by the optical element functioning as the reflection mirror. Thus, this laser system provides a uniform pumping of a laser medium having a relatively large cross-section, thus providing improved excitation efficiency and mode quality. Further, this laser system is configured such that the output mirror is not substantially exposed to the pumping beam, thus providing increased output power and improved stability of the entire system.

摘要： A handle of a portable power-driven machine such as a chain saw has an upper handle member and a lower handle member which are adjoined to each other to present the form of a handle. The handle also has an anti-slip rubber layer lining the outer surface of the lower handle member. The rubber layer has an upper end folded back on the upper ends of both side walls of the lower handle member to overlie the upper inner periphery of the lower handle member. The upper handle member has vertical downward projections which engage the folded end portion of the rubber layer overlying the upper inner periphery of the lower handle member.

摘要： A braking system including a sensing lever operated when the forward portion of a chain saw moves upwardly with a jerk due to a kickback phenomenon or the hand of an operator slips from a handle during operation, a brake device, and a direct-acting interlocking member connecting the sensing lever to the brake device. A force exerted on the sensing lever and a force of a spring locking the sensing lever are both transmitted to the brake device through the interlocking member.
