A non-combustion suction device includes: a mouthpiece having a suction port; a container configured to accommodate an aerosol source; and a heater including: a porous ceramic substrate that permits infiltration of the aerosol source; a glass layer at least in part on the porous ceramic substrate; a pair of electrode patterns; and a resistor pattern on the glass substrate, the resistor pattern connects the pair of electrode patterns to each other; and a power source connected to the pair of electrode patterns. The power source is configured to supply a power flow through the pair of electrode patterns to cause the resistor pattern to generate heat which atomize, into an aerosol, the aerosol source infiltrated in the porous ceramic substrate; and the porous ceramic substrate has a ratio of porosity to tortuosity of 21 or more.

A degree of freedom of a hypoid gear is improved. An instantaneous axis in a relative rotation of a gear axis and a pinion axis, a line of centers, an intersection between the instantaneous axis and the line of centers, and an inclination angle of the instantaneous axis with respect to the rotation axis of the gear are calculated based on a shaft angle, an offset, and a gear ratio of a hypoid gear. Based on these variables, base coordinate systems are determined, and the specifications are calculated using these coordinate systems. For the spiral angles, pitch cone angles, and reference circle radii of the gear and pinion, one of the values for the gear and the pinion is set and a design reference point is calculated. Based on the design reference point and a contact normal of the gear, specifications are calculated. The pitch cone angle of the gear or the pinion can be freely selected.

In a crankshaft of an in-line four-cylinder engine, an arm that is closest to a flywheel has a greater average thickness in a direction of the rotation axis of the crankshaft than those of other arms. Two of the arms that are coupled to both sides of the third journal from the flywheel each have a center of gravity closer to its own counterweight compared to the centers of gravity of the arms that face the two arms with corresponding crankpins in between. Accordingly, the rigidity against torsional deformation and the thickness of oil films on the journals are reliably maintained while suppressing increase in the weight of the entire crankshaft.

Local observer frame LOC which is located near a body and moving on a global coordinate system is used for locally observing the body together with the global coordinate system. The rigid body displacement and elastic vibration of the body are represented by rigid body modes and elastic modes respectively, and analyzed by modal analysis uniformly handling these rigid body modes and elastic modes.
