Latest Patents

Aikawa's latest patents include an advanced encoder design. The first patent discloses an encoder that features a rotary member and a fixed member. The fixed member is equipped with an electrode that has A-channel, B-channel, and C-channel patterns. The rotary member contains contacts that oppose the electrode. The A-C state switches from OFF to ON with each rotation of the rotary member for one click angle from a stable click position in both clockwise (CW) and counter-clockwise (CCW) directions. During CW rotation for one click angle, the B-C state remains unchanged from OFF, while during CCW rotation for one click angle, the B-C state switches twice between ON and OFF.

The second patent describes an encoder that includes an electrode pattern with pairs of non-conductive portions and multiple sliders that contact the electrode pattern. This encoder consists of a rotary member with a predetermined electrode pattern and a fixed member that has multiple channel contacts opposing the electrode. The rotary member has stable reference phases where at most one pair of contacts is ON (in electrical contact) and at least another pair is OFF (not in electrical contact). When the rotary member is rotated from one reference phase, both pairs of contacts are temporarily ON before reaching the adjacent reference phase. The pairs of contacts that are ON or OFF at the adjacent reference phase differ depending on the direction of rotation, allowing a counter to be incremented or decremented accordingly.
