The system converts an analog input signal into a digital output signal while avoiding interference, such as clipping. The system derives two signal components having differing signal magnitude levels from the analog input signal. The signal components are subjected to independent analog to digital conversion, such as through low resolution analog to digital converters. The system determines weighting factors for the two signal components based on at least one property of at least one of the signal components, such as the level of at least one of the signal components. The signal components are weighted. The weighted signal components are merged.

When generating an origin signal of an encoder having a scale on which an incremental pattern and the origin pattern are formed, an origin signal having a necessary position and width is generated by software based on an origin waveform obtained from the origin pattern. This enables origin detection with excellent repeatability, S / N ratio (pulse width), and bidirectionality while maintaining ease of mounting and adjustment.

A liquid-jet head selectively forms a large dot or a small dot. The large dot is ejected when a plurality of pulse signals are selected, and the small dot upon selection of a smaller number of the pulse signals. There is a contraction of the pressure generating chamber to eject a droplet through the nozzle, and a vibration damping step. The drive waveforms are set to implement this approach, and have particular characteristics.

A strap comprising a main body portion formed in a belt shape and provided with a first loopback end portion formed by intermediate portion being looped back; and a locking mechanism provided with a first support portion slidably supports one region of the main body portion viewed from the first loopback end portion, and a second support portion supports an end portion provided at an opposite side from the first loopback end portion on an other region, and the locking mechanism being switchable between a free state and a locked state.

The invention provides an adjustable door stopper assembly, which belongs to the technical field of door stoppers. It solves the technical problems of inconvenient and poor stability of the existing door stopper. The adjustable door stopper assembly includes a cylinder with an open end, and a limit pin that can reciprocate axially along the cylinder and always has a tendency to move outward is arranged in the cylinder, and the open end of the cylinder The screw connection is equipped with an adjustment block that can be fed along the axial direction of the cylinder through rotation. The outer end of the limit pin is in the shape of a round head and penetrates and extends out of the adjustment block. There is a limit portion on the limit pin. The limit part can abut against the inner end of the adjustment block in the axial direction and form a limit in the circumferential direction, and the limit pin can cooperate with the cylinder in the circumferential limit. When the limit pin moves inward, the adjusting block can release the circumferential limit or the limit pin can release the circumferential limit. The adjustable door stopper assembly ensures the convenience of adjustment and ensures a more stable state after adjustment.
