An optical pickup device includes a light source for emitting light beam onto a recording medium. A lens is provided in an optical path between the light source and the recording medium. The lens converges the light beam to create a focusing spot on the recording medium. A tracking error detector receives a light beam reflected from the recording detector also receives a reflected light beam to detect a focusing error. A controller receives an output from the tracking error detector and the focusing error detector to produce a tracking error correction signal and a focusing error correction signal. A deflection angle adjuster is provided in the optical path and is responsive to the tracking error correction signal. The angle adjuster adjusts a deflection angle of the light beam. A refractive index adjuster is provided in the optical path and is responsive to the focusing error correction signal. The refractive index adjuster adjusts a refractive index of the light beam.

A counterweight (8) is attached to the rear side of a revolving frame (6), and an engine (9) is mounted in a transverse direction in front of the counterweight (8). A heat exchanger (12) is located on the left side of the engine (9), and a left-hand side door (17) is located on the left side of the heat exchanger (12). An air cleaner (24) is accommodated in an air cleaner chamber (19) which is provided in a space enclosed by the counterweight, left-hand side door and heat exchanger. In this state, a casing (25) of the air cleaner has an opening portion (25A) to permit insertion and extraction of a filter element (26). Thus, at the time of a maintenance work for the air cleaner, one can draw out the filter element from the opening portion of the casing simply by opening the left-hand side door.

In a method for checking for leakage from tubular batteries, when tubular batteries (Ba) are fed with their respective axial centers aligned in parallel to each other to pass through a leakage check mechanism (12), a sealed end face (33) of the tubular batteries (Ba) is irradiated with an X-ray (34). A fluorescent X-ray (40) coming out of the sealed end face (33) is incident upon a detector (39) through a detection window (35). In accordance with the result of analysis on whether the incident fluorescent X-ray (40) contains a fluorescent X-ray (40) associated with an electrolyte component, it is determined whether leakage has occurred from the tubular batteries (Ba). A length (L1, L3, L5) of the detection window (35) in a direction of feed of the tubular batteries (Ba) is set to be less than a spacing (C1, C2) between the tubular batteries (Ba). A length (L2, L4, L6) of the detection window (35) in an orientation orthogonal to the direction of feed is set to be greater than an outer size (R1, R2) of the cross-sectional shape of the tubular batteries (Ba) in an orientation orthogonal to their axial center. It is thus possible to highly accurately determine occurrence of leakage from a tubular battery at high speeds by X-ray fluorescence analysis.

The conjugated diene rubber contains at least 5% by weight of a structure comprising at least three conjugated diene polymer chains bonded through a polyorganosiloxane. The conjugated diene rubber gives, when silica is incorporated therein, a rubber composition having good processability and giving a crosslinked rubber having reduced heat build-up, good wet grip performance and good abrasion resistance.
