A readily movable cafe chair that is multi-functional and therefore useable by its seated occupant in various ways. The chair includes a back section formed by a sculptured panel defining a flat figure whose head merges with a body region having outwardly swelling hips from which extend widely spaced legs between which is a crotch zone. Joined to the back section is a front section having a lobe-shaped seat whose front end is supported by a pair of front legs which are spaced from the rear legs and are coupled thereto by a fork. The arcuate rear end of the seat is attached at its apex to the crotch zone of the back section. The sides of the lobe-shaped seat curve inwardly toward the crotch zone to create free spaces adjacent the rear legs of the chair. Thus the occupant may seat himself in a direct mode facing forwardly, or in a reverse mode facing rearwardly. The occupant when seated with his back against the back section can safely back-tilt the chair.

Signals derived from a moving shuttle table are utilized to trigger a cavity-dumped YAG laser whose output pulses are directed to machine successive lines of an iron oxide film in a spot-by-spot manner. Machining of the film to form a high-quality reticle requires that the amplitude of the laser output pulses be maintained relatively constant even in the presence of mechanical vibrations and electrical noise which ordinarily tend to produce large fluctuations in the output power of the laser. This is achieved by interposing a phase-locked loop between the output of the shuttle table and the input of the laser. In addition, the loop enhances the machining operation by providing a capability to easily multiply the repetition rate of the pulses derived from the table.
