The lateral wall (102) is designed as a plastic component and has a first receiving area and a second receiving area (110).

The second cut-out is positioned on the shaft opposite from the first cut-out; the first and second cut-out thus defining a thinned region in the probe.

The plurality of depressions (112C) are formed from a first depression (C1), and at least one second depression (C2) other than the first depression (C1).

The first counterweight has a first gear, a lead filled first void and a phenolic filled second void diametrically opposed from said first void.

The second counterweight has a second gear, a lead filled third void and a phenolic filled fourth void diametrically opposed from the third void.

The first fitting component comprises a rear ferrule recess and a front ferrule recess.

Each recess has a bottom (8).

The sensor is provided with a gap-formed member, which has formed therein a gap for oil, said gap having the lubricant oil enter.

A recess is formed in the silicon body.

A second recess (326) is provided at the corner opposing the first recess (325) in the tape cassette (30).

At least one recess (14) is then generated and optionally a reinforcing element is introduced into the above.

A silicon element extends into the recess.

A recess (117) is provided in the member.

The pin has a concave spherical recess.

A recess intercepts the optical path.
