Abstract: The present invention is such that, in a circuit for preventing an arc discharge through the application of a reverse voltage pulse, in the case where, after the application of the reverse voltage pulse has been ended, the generation of an arc discharge is detected by an arc discharge detecting means (23), a reverse voltage generated by a reverse voltage generating means (12) is applied within 1 to 10 &mgr;s to a sputtering source to lower the probability of generating a continuous arc discharge and, through a diode (D10) connected in series with the sputtering source (14) and a resistor (r10) connected in parallel with the diode (D10), a current at a time of applying the reverse voltage is restricted, thus lowering a continuous arc discharge resulting from the reverse arc discharge.

Abstract: A photo printer system comprises a magnetic storage for storing a print data sent from a host computer, a bit map memory for storing a print dot data, and a printer engine for printing the contents of the bit map memory. The system includes a program which operates on the magnetic storage to serve as an external storage for the host computer and on the bit map memory to serve as a cache memory in response to a data read/write command issued by the host computer, and a CPU which controls the execution of the program. At least in a non-print process mode, the system forms a data path so that the host computer can access to the bit map memory and magnetic storage so as to have a bidirectional data read/write operation. In another mode, the system forms a data path so that image data picked up with an image scanner is saved directly in the bit map memory and the image data is sent to the host computer by request.

Abstract: Edible fats and oils are extracted from oil-bearing materials by loading the raw materials onto an inlet end of a flat and fixed conveying surface having elongate slits therein. The materials are conveyed from the inlet end to the outlet end of the conveying surface by scrapers moved by endless chains. Oil extracting solvent is sprayed onto the material on the conveying surface, to produce miscella, which flows through the slits in the surface and into hoppers beneath the surface. The miscella is circulated back to additional sprayers located upstream of the solvent sprayers for spraying the miscella onto the upstream end of the conveying surface. The resulting concentrated miscella is collected in hoppers beneath the surface and delivered to a further use.
