  • Patent number: 5127096
    Abstract: An information processing apparatus includes a program memory (4, 40) and circuitry for switching mapping schemes so as to deal with both direct and bank mapping schemes without alteration of programs. The program memory (4) includes a first memory area (14, 15) formed of a plurality of memory blocks for storing a first program (100) for the bank mapping and a second memory area (16, 17) utilized as a memory block for storing a second program for direct mapping. In the bank mapping, each memory block is mapped into a same address area of an address space of the processor. In the direct mapping, the first and second memory areas are mapped in one-to-one correspondence into the address space. Alternative program memory (40) includes a first memory block (50) storing a first program and a second memory block (60) storing a second program. A predetermined identification information ("JA") is stored in a predetermined memory location of the second memory block.

  • Patent number: 5061368
    Abstract: A system for treating waste water using a particulate body formed by covering and fixing nitrifying bacteria. In the system, the particulate body is inserted in a nitrifying vessel which including therein an air diffusion device for supplying oxygen to the nitrifying bacteria and a particulate body separation device for preventing the outflow of the particulate body. The nitrifying vessel and the particulate body contained therein are used as a nitrifying vessel unit and one or more such nitrifying vessel units are arranged within a treating tank. Waste water is circulated between the nitrifying vessel and the other portions of the treating tank than the nitrifying vessel by means of the air lift effect of the air diffused from the air diffusion device.

  • Patent number: 5017621
    Abstract: The present invention provides polypropylene resin pre-expanded beads formed by shrinking polypropylene resin pre-expanded beads originally having a bulk density of not higher than 0.0930 g/cc to give them a bulk volume ratio of 10-75% at normal temperature and normal pressure, a manufacturing method thereof and an expansion-molding method with the aforementioned pre-expanded beads. According to this invention, it is possible to greatly reduce storing and transporting costs per unit weight of pre-expanded beads.

  • Patent number: 4979963
    Abstract: This invention provides a process for coloring expandable beads of polystyrene resins which comprises suspending expandable beads of a polystyrene resin and a dye in water in a closed vessel and heating this aqueous suspension at a temperature above the softening point of the expandable beads, wherein the closed vessel is filled up almost completely with the aqueous suspension and heating is conducted without further addition of any blowing agent, whereby the expandable beads are impregnated uniformly with the dye. According to this process, uniformly colored expandable beads of polystyrene resins are obtained at a high efficiency of dye impregnation without using any impregnation aid or the like, the expandable beads being capable of forming beautiful molded foams of uniform color.
