摘要： When an input picture is inputted to a video interface and stored in a reordering memory, the input time is recorded utilizing a reference time generator and a frame sync signal, and a frame memory to be encoded by an encoding unit is designated using the time information. Therefore, an encoder, which can perform stable encoding even when intervals of vertical sync signals are varied, is realized.

摘要： A running carriage (33) delivers, spreads, and piles a sheet material to be spread to form a piled sheet material (24), while running on a spreading table (22) of a cloth spreading machine (21). The piled sheet material (24) is placed on an underlay sheet (25) which has a larger area than that of the piled sheet material (24). At the bottom of the running carriage (33), a foot presser (27) is provided. The foot presser (27) is designed to be vertically displaced by a cylinder (28). A blower motor (29) drives a fan (30) to blow air through nozzles (31) towards the surface of the spreading table (22), thereby reducing the load of the piled sheet material (24). The underlay sheet (25) is pressed by the foot presser (27) and the running carriage (33) starts running, whereby the piled sheet material (24) is delivered.

摘要： A laser oscillator that has a resonator cavity defined by oppositely disposed discharge electrodes as well as a plurality of total reflecting mirrors and a partial reflecting mirror, the resonator cavity volume containing the path of a laser beam generated by the oscillator. A laser gas medium is used to control the temperature of the oscillator and is directed in a main flow generally transverse to the path of the laser. A side flow is taken from the main flow and is directed by a duct to a position in the vicinity of the partial reflecting mirror. In order to avoid excess heating of the gas medium in the vicinity of the partial reflecting mirror and to avoid directly impacting the mirror with the gas medium, a U-shaped structure is disposed at the exit of the side flow duct, proximate to the mirror, for directing the side flow in the vicinity of but away from the mirror.

摘要： A laser system wherein, in order that a high-output and high-quality single mode of a cross sectional area larger than the beam diameter determined by the construction of a resonator can be obtained stably, although this has heretofore been impossible, there is used a coupling mirror provided with a partial reflection film and an antireflecting film, a laser beam mode is selected using the partial reflection film, a phase difference between laser beam portions caused by a difference in construction between the partial reflection film and the antireflecting film is compensated using a phase difference compensating means, and there is formed an aperture whose diameter is set to a value of not larger than four times the diameter of the partial reflection film.

摘要： A laser oscillator comprising a laser resonator having a plurality of mirrors for directing the laser energy from source to exit apertures, the mirrors being constructed and mounted adjustably for reducing parasitic oscillations. The mirrors are mounted in adjusting members that have channels therein for coolant and are provided with heat insulating members that minimize heat gradients and unwanted heat transfers that may result in the distortion of the reflecting surfaces. In addition, the mirrors are angled so that light paths are defined that present a Z-shaped turning pattern. Apertures proximate to the mirrors through which the light beams are directed are offset from a common plane so that a reflective surface is not within the aperture of the opposing reflective surface. One or more of the apertures can be so offset to reduce the possibility of parasitic oscillations. Further, the reflectors can be angled and the apertures sized so as to eliminate parasitic oscillations.
