A groove and a recess are formed on one surface of a base material, the recess being communicated with the groove and having a width and a length longer than a width of the groove. After that, liquid droplets are landed on the recess to charge a liquid into the groove communicated with the recess. Further, the liquid charged into the groove is solidified. Accordingly, the liquid can be charged into the groove having the narrow width, by merely landing the liquid droplets on the recess having a large areal size. Therefore, a fine pattern can be easily formed on the base material.

A holding device comprises a cylindrical or prismatic, porous ceramic blank and elements for clamping in a machine tool for processing the blank by removing material, in order to produce a ceramic workpiece. A narrow frame is fixed by an adhesive connection over at least part of the periphery of the blank, which is held without stresses, in the area of a plane encompassing the longitudinal middle axis (A) of the blank. The frame only covers a small part of the surface of the blank and can be detached and held in a stable holder with a clamping adapter, in such a way that it cannot slide. The entire combination is fixed in the machine tool in such a way as to be resistant to twisting and sliding. The ceramic workpiece emerges continuously form the ceramic blank without predetermination of the advance direction, until holding segments which can then only be freely selected according to number and location have been formed. The holding segments end on the residual material of the blank in the area of the frame or on the frame itself. The holding device is used especially as a workpiece for producing fully ceramic dental prostheses, particularly crowns or bridges.

An apparatus for manufacturing semiconductor devices includes a supporter portion on which a semiconductor substrate is placed, a nozzle portion for injecting a fluid to an edge of the substrate placed on the supporter portion, a shielding cover for preventing the fluid injected from the nozzle portion from flowing to a shielding portion among a pattern-formed portion, and a shielding cover moving portion device for moving the shielding cover up and down. The apparatus makes it possible to prevent a chemical solution injected to the edge of a wafer from flowing to a shielding portion of the wafer when the wafer edge is etched.

An attached storage media link has a self-timed interface (STI) in which a clock signal clocks bit serial data onto a parallel, electrically conductive bus and the clock signal is transmitted on a separate line of the bus. The received data on each line of the bus is individually phase aligned with the clock signal, providing a high speed, cost effective interface to a direct access storage device.
