[Problem] To realize a predetermined 'aseptic level of the containers' without introducing a container sterilizing machine and to reduce the burden for adjusting the temperature of the preform. [Means for Solution] A metal mold for molding, wherein a space width (t) of at least the body portion in the space width for forming a thickness of from the body portion to the bottom portion of the preform is set to lie in a range of 1.18 to 2.11 times as great as a space width (t) for forming a thickness of an upper end portion of the mouth portion of the preform. At the time of the compression molding, the preform is taken out in the state of a high temperature from a compression-molding machineand is fed to a bottle-producing unit C while maintaining the state of a high temperature. Further, the inner surfaces of a clean box I in which the units are placed and the outer surfaces of the units are sterilized, and the interior of the clean box I maintains a positive-pressure state with the filtered clean air. The bottle-producing unit C and a filling/sealing unit D are neighboring and directly coupled to each other in the same clean box, and are partitioned by a WBZ

A device for printing an image onto a surface, such as food containers, employs a laser that is scanned across a surface to produce a latent image on a charged photosensitive surface formed on the surface. The surface is moved relative to the laser source while the laser is activated and deactivated according to a pattern of signal pulses from a control circuit. The device thus forms a raster image. To form very fine images, the control circuit must produce pulses with very small steps in duration. The control circuit of the present invention divides a digital value representing a duration of firing of the laser into high and low order bit sequences. The high order bits, representing a value M, are applied to a counter that generates a first pulse M clock cycles long. The low order bits and the first pulse are applied to a delay circuit. The delay circuit generates a delayed version of the first pulse, which is delayed by an amount represented by the low order bits. The first and second pulse signals are logically ORed to produce the control pulse for the laser.

Dots for producing a multiple tone electrostatic latent image are formed by selectively discharging a charged surface with a scanned laser beam. The multiple tones are produced by pulse width modulation of the laser beam according to the tones required in the dots. High resolution is maintained by limiting the diameter of toner particles to 1/5 to 5 times a minimum exposed dot dimension of less than 1 micron. A laser beam exposure device includes a galvanometer mirror from which the scanning laser beam is reflected. The galvanometer mirror is tilted in synchronism with the conveying direction of the surface being scanned in order to maintain focus of the laser beam on the surface.
