摘要:
A solid shaped product is fabricated by using a liquid. In a solid shaped-product fabrication method of discharging, to a target, a droplet from a nozzle of a liquid discharge unit for discharging a liquid, and fabricating a solid shaped product, the liquid contains at least water and a colorant that is dissolved or dispersed in the water, the droplet has a specific surface area of 0.2 m 3 /g or more and 0.5 m 3 /g or less on condition that the droplet is approximated by an ideal true sphere on the basis of a volume when the liquid is caused to fly as a single droplet, and the droplet having the specific surface area in such a range is continuously discharged to the target at 1 Hz or higher and 100 Hz or lower.
摘要:
An electrochemical display unit capable of being simplified in unit construction and reduced in cost with a simple matrix drive implemented. An electrochemical display unit that effects displaying by using electrochemical depositing/melting of a metal. The unit is driven by a simple matrix drive system, and uses as a threshold value in a simple matrix drive a deposition over-voltage at which metal ions deposit as a metal. The drive voltage is up to two times the deposition over-voltage. The electrochemical display unit has a transparent electrode and a counter electrode, and displays images by depositing/melting of a metal on the transparent electrode, the potential difference between a metal deposited on the transparent electrode and the counter electrode being set to be less than a deposition over-voltage. Ideally, the same metal as one deposited on the counter electrode is used.

For example, a semi-spherical system holding mechanism 8 such as to cover the head portion of the user is provided in the upper portion of a user holding mechanism 9 such as chair, sofa, or the like. A display apparatus 7 is fixed in the system holding mechanism 8. In the display apparatus 7, a video image displayed on a display panel 14 is enlarged by a lens 13, so that a virtual image is formed. The virtual images which are observed by the right and left eyes of the user are arranged at the same position in a space.
