  • Patent number: 10413970
    Abstract: There is provided a method for manufacturing a three-dimensional shaped object by alternate repetition of a powder-layer forming and a solidified-layer forming by an irradiation with a light beam in order to provide a selective laser sintering method capable of reducing a warp of the three-dimensional shaped object, the warp being due to a stress around an upper surface of the three-dimensional shaped object. Especially, in the present invention, a part of a region for the formation of the solidified layer is not irradiated with the light beam to form a non-irradiated portion, thereby providing at least one slit-groove at an upper surface of the three-dimensional shaped object, the slit-groove being for reducing a stress of the three-dimensional shaped object.

    Abstract: To reduce the heat input to the bottom of the crucible and to control heat extraction independently of heat input, a shield can be raised between a heating element and a crucible at a controlled speed as the crystal grows. Other steps could include moving the crucible, but this process can avoid having to move the crucible. A temperature gradient is produced by shielding only a portion of the heating element; for example, the bottom portion of a cylindrical element can be shielded to cause heat transfer to be less in the bottom of the crucible than at the top, thereby causing a stabilizing temperature gradient in the crucible.

    Abstract: A mold includes a fluid channel, a fluid inlet, and a fluid outlet. The mold is manufactured, at least in part, from a PTC-ceramic material. Upon application of a voltage to the mold, the mold is heated such that a fluid passing through the fluid channel may also be subject to heating.

  • Patent number: 7444829
    Abstract: The peel off between an ice making plate and an insulating layer or between the insulating layer and heating means is prevented so that an ice making operation can be performed efficiently. Also, a metal plate is insulated from the heating means reliably. An evaporation pipe 14 and electric heaters H1 to HN are provided in an ice making member 11. A coolant is circulatingly supplied through the evaporation pipe 14 so as to cool the ice making member 11 and ice making water is supplied to the ice making member 11 so as to form an ice block M during the ice making operation. During the deicing operation, heat is generated in the heaters H1 to HN by applying current so that the ice block M is removed from the ice making member 11 by melting.

  • Patent number: 7182902
    Abstract: A method for making crayons is provided. The method employs an apparatus which includes a base that houses a heating component, a melt pan disposed to absorb heat from the heating component, a mold, and a cover. The melt pan receives crayon material and contains it as the heating component increases the temperature, causing the crayon material to liquefy. The liquefied crayon material can then be drained by the user of the device, into a mold with crayon-shaped cavities. A timer and a cover prevents access to the melt pan and the mold during particular operating conditions of the apparatus.

  • Patent number: 7156361
    Abstract: Metal traces and solder bump pads are formed on a semiconductor substrate by way of a semiconductor template that has been micromachined to receive solder paste material. The solder paste material is then formed into precisely controlled ball shapes and metal trace geometries. First, a semiconductor substrate is covered with a mask material for protecting selected surfaces of the substrate that are not to be etched. Next, a mask is applied in order to etch the substrate surface below. Solder ball sites and metal trace channels are formed at this time. A solder nonwettable material is applied to the exposed surfaces of the solder ball sites and the metal trace channels. A solder paste can then be applied uniformly across the surface of the substrate, thus filling in any sites and channels, or both, that are used to form the balls or metal traces desired.

  • Patent number: 7152424
    Abstract: An ice tray includes a tray section and a heater. The tray section has a first face and a second face opposite to the first face. The first face temporarily retains water and the water is cooled to make ice. The heater is unitarily molded with the tray section at the second face, and warms the tray section for the ice to come off the tray section.

  • Publication number: 20020132024
    Abstract: Molding apparatus (10) is provided which allows use of a particulate non-liquid molding material (121) to produce a variety of articles, such as frustoconical barrel segments (122). The apparatus (10) includes a female mold segment (18) including generally annular inner and outer sidewalls (70, 76) and a complemental male mold section (20) having an annular sidewall unit (30). In use, a molding material (121) is placed between the sidewalls (70, 76) and the section (20) is shifted so that it telescopes within the section (18); this compresses the material (121) to a desired final shape, which is then hardened to yield the final product (122). An optional wear insert (26) can be used with female mold section (18), which can be replaced as needed and assists in cleaning of the apparatus (10).
