The logo is a TiB hollow needle. It was "extracted" from a mixture of α-titanium (hcp) and orthorhombic TiB (a = 0.61, b=0.31, c=0.56 nm).
The interest in TiB. Reinforcing Ti alloys such as Ti-6Al-4V) with TiB reduces grain size while increasing both bulk modulus and tensile strength. This improved performance at high temperature leads to use in valves -- initially in the Toyota-manufactured valves for Japan-only Toyota Altezza. More recently the values are manufactured for Yamaha in their motorcyle engines whose higher profit margin makes the added cost acceptable.

Fine needles are produced via rapid solidification for concentrations less than 0.5 wt.% B. Subsequent heat treatments have a typical profile of 1100 C for 1 hr followed by slow cooling or quenching. Polishing the surface and then etching with HF reveals that many of the needles have alpha-Ti interiors. The resulting hollow needle consists of exfoliated layers with many sides. The logo has a 200 micron diameter, hollow needle in a mixture of other cylinders and whiskers.
