20090059534 | ELECTRONIC EQUIPMENT - In order to ensure waterproofing between a resin enclosure case and a heat sink, a canopy structure is provided in a portion, in which water is likely to penetrate, so as to prevent the water from entering the portion, thereby directing the water flow to the outside of the enclosure. This makes it easy to install and remove an electronic unit, so that an electronic component integrally formed with the heat sink can be easily replaced. | 03-05-2009 |
20100181108 | ELECTRONIC EQUIPMENT - Electronic equipment installed outdoors to house an internal unit is provided, meeting the waterproof standard and having an easily replaceable structure of the internal unit. The electronic equipment has an enclosure having a cover and a case with an opening and an air vent, and an internal unit in which an electronic component is mounted. The internal unit has a heat sink and radiation fins for releasing heat generated by the electronic component. The fins are inserted into the opening. The heat sink has a draining portion formed below the fins in a direction perpendicular to an extending direction of the radiation fins, a groove for waterproofing around the fins except an upper portion thereof, and two protrusions for fitting above the fins. The case has a rib for waterproofing around the opening except an upper portion thereof, and two holes for fitting above the opening. | 07-22-2010 |

20110314990 | GLASS CUTTING MACHINE, GLASS CUTTER, AND GLASS CUTTING METHOD - A glass cutter is provided which can form, using a wheel, a uniform crack in glass even when a projection or an earlier-formed scribe line is present on the glass. When the wheel is moved on the glass, a fracture layer is formed causing a rib mark to be formed below the fracture layer and a crack to be formed below the rib mark. To cut the glass, the crack is required to be formed uniformly. Applying a force to resist the rotating force of the wheel makes it possible to form a uniform crack even when a projection is present on the glass. This improves glass cutting yield. | 12-29-2011 |

20090084329 | MALFUNCTION DETECTION DEVICE FOR HOT WATER SUPPLIER - A malfunction detection device for a hot water supplier has a tank temperature detection thermistor for detecting a hot water temperature of a hot water storage tank and is configured such that when the detected hot water temperature of the hot water storage tank is a reference temperature or higher, a relay provided at a tank printed circuit board stops power supply from a tank unit to a heat pump unit. A heat pump shutdown command is a standby power saving command for saving a standby power of the heat pump unit. | 04-02-2009 |

20110084019 | ANTITHROMBOGENIC SURFACE - Provided is a surface showing excellent antithrombotic properties. Also provided is a medical device having the same. An antithrombotic surface comprising polymer layers which are in different charged states and alternately layered, characterized by having three-dimensional peaks and valleys formed thereon. The antithrombotic surface as described above which is further characterized in that the peaks and valleys are 15 nm or more but not more than 200 nm in height and depth respectively. A medical device characterized by being provided with the antithrombotic surface as described above. Thus, a thin and highly antithrombotic surface or medical device can be obtained by a relatively convenient method. | 04-14-2011 |

20100045607 | OPERATION INPUT DEVICE AND CHARACTER INPUT DEVICE - Provided is an operation input device to be attached to a base having a recessed portion including a side surface that faces one end of the base. The operation input device includes: a side surface portion formed into a shape corresponding to the side surface of the recessed portion; and first and second holding portions which fix the operation input device to the base by sandwiching the base, in which: a surface of one of the holding portions, which contacts the base, is bent toward the other holding portion; a tip end portion of the first holding portion moves toward an opposite side to the second holding portion, whereby the operation input device is attached to or detached from the base; and the side surface portion contacts with the side surface of the recessed portion, when the operation input device is attached to the base. | 02-25-2010 |

20080217234 | Device for treating fluorine-containing water - There is disclosed a device for treating fluorine-containing water in which for-treatment water can be treated so as to set a fluorine concentration to a drainage standard or less without adding a reagent such as a pH adjuster to change a pH of the for-treatment water if possible. A treatment device includes a first treatment means for adding, to fluorine-containing for-treatment water, a reactive compound which reacts with fluorine to form a fluoride and which does not apply an OH group, so that a suspension is formed; a second treatment means for separating the suspension obtained by the first treatment means into a solid and a liquid; and a third treatment means for bringing a permeation liquid separated by the second treatment means into contact with a fluoride ion adsorbent. | 09-11-2008 |

20090101560 | HYDROFLUORIC ACID TREATMENT APPARATUS - When hydrofluoric acid is introduced into a treatment tank in a pH adjustment unit, an alkali chemical is also introduced thereinto to set pH of first treated water in the treatment tank to be larger than pH of the wastewater. Moreover, a third path (circulating path) is connected to the treatment tank to circulate the first treated water. Then, pH adjustment is performed until second treated water having a pH value within a desired range is generated. The second treated water having the pH value adjusted to a desired value after the pH adjustment is transferred to the reaction tank for reaction with calcium. Thus, deterioration in treatment efficiency can be prevented. Moreover, the pH meter is provided in the circulating path and never comes into direct contact with the wastewater. Thus, the pH meter can be protected from the hydrofluoric acid. | 04-23-2009 |
