Abstract: Ophthalmically compatible contact lenses include lens bodies configured for placement on a cornea of an animal or human eye. The lens bodies are made of a hydrophilic silicon-containing polymeric material. The lens bodies have oxygen permeabilities, water content, surface wettabilities, flexibilities, and/or designs to be worn by a lens wearer even during sleep. The present lenses can be worn on a daily basis, including overnight, or can be worn for several days, such as about thirty days, without requiring removal or cleaning.

Abstract: An image forming apparatus includes: a piezoelectric element with a common electrode on one side and an individual electrode on another side; a nozzle; and circuitry. The circuitry selects one from drive signals and supplies the one drive signal to the piezoelectric element via the individual electrode, to discharge a droplet through the nozzle to form an image. Each drive signal includes waveform pulses including a main pulse that rises in a slope shape during a rising time and finishes rising at an end time. The circuitry generates the drive signals so that the end time of a less influential drive signal other than a most influential drive signal falls within a range of the rising time of the main pulse of the most influential drive signal; selects the one drive signal based on an image to be formed; and supplies the one drive signal to the piezoelectric element.

Abstract: A liquid discharge head includes a nozzle to discharge a liquid, an individual chamber communicating with the nozzle, a supply channel communicating with the individual chamber to supply the liquid to the individual chamber, and a discharge channel communicating with the individual chamber to discharge the liquid in the individual chamber. A fluid resistance of the supply channel is greater than a fluid resistance of the discharge channel.

Abstract: A liquid discharge head includes a plurality of nozzles from which liquid is discharged, a plurality of individual-liquid-chambers communicating with the plurality of nozzles, respectively, a plurality of individual-drainage-channels communicating with the plurality of individual-liquid-chambers, respectively, a drainage-side common-liquid-chamber communicating with each of the plurality of individual-drainage-channels, a filter having filter holes and disposed between the plurality of individual-drainage-channels and the drainage-side common-liquid-chamber, and an intermediate-drainage-channel disposed between the filter and the plurality of individual-drainage-channels. The intermediate-drainage-channel faces the filter and communicates with two or more of the plurality of individual-drainage-channels. A cross-sectional area of the intermediate-drainage-channel is greater than a cross-sectional area of each of the plurality of individual-drainage-channels communicating with the intermediate-drainage-channel in a direction perpendicular to a direction of liquid flow.
