摘要:
An ink-jet printing device is described, said device comprising a first reservoir designed to contain a first volume of printing fluid at a first height with respect to a reference plane, a supply system for forcing the printing fluid towards the first reservoir and a second reservoir designed to contain a second volume of printing fluid at a second height with respect to the reference plane. The second height is less than the first height by a value. The device also comprises a conduit designed to receive the printing fluid from the first reservoir and convey it towards the second reservoir and an ejection plane in which ejector units lie. The ejection plane is arranged in a position higher than the average of the first height and the second height, so as to generate a back pressure in the ejector units. The flowrate of the printing fluid is between about 5 and about 10 times the maximum flowrate which can be ejected from said ejector units. The printing fluid may be a ceramic ink.

This holder (2) for a replacement battery (12) for a watch, in addition to a housing for holding such battery, includes means (15) for gaining access to the watch battery which is to be exchanged. Accessory thereto, the holder may serve as a key holder and present the advantage of of always being carried by the person wearing the watch. The holder is in two parts: a sheath (17) in which a drawer (18) is fitted, such drawer bearing the replacement battery (12) and an incorporated tool (15) which enables extraction of the exhausted battery from the watch.

A timepiece including a decorative pattern (30) rotating with the arbor (8) for one of the hands under a first crystal (1). In order to avoid permanent deformation of the arbor brought about by shocks, the decorative pattern is surrounded by a protective wall (11) which may be in the form of a bore in a second crystal (2) located between the first crystal and the dial (5) of the watch.
