  • Patent number: 8676499
    Abstract: Movement guidance systems, devices, methods, and programs set a guidance branch point on a guidance route. The systems, devices, methods, and programs acquire a position and a shape of the guidance branch point and a prior branch point, and determine whether the prior branch point is adjacent based on the acquired information. The prior branch point is adjacent when the prior branch point exists within a first predetermined distance from the guidance branch point and is connected with a road in a same direction as the guidance branch point. When it is determined that the prior branch point is adjacent, the systems, devices, methods, and programs complete verbal guidance for the guidance branch point at a timing at which the movable body is located at a guidance end point that is located a second predetermined distance before the prior branch point.

  • Patent number: 8549874
    Abstract: A refrigeration system (10) includes: a refrigerant circuit (11) performing a vapor compression refrigeration cycle by including a compressor (30), a utilization side heat exchanger (24) configured to allow refrigerant to perform heat exchange with air, and a heat-source side heat exchanger (25) configured to allow refrigerant to perform heat exchange with water; and a casing (14) housing the utilization side heat exchanger (24). The casing (14) contains a power supply (31) including a power semiconductor device and configured to supply electric power to the compressor (30), and also contains a cooler (19) configured to cool the power supply (31) by supplying air to the power supply (31).

  • Patent number: 5783057
    Abstract: A method of purifying a copper electrolytic solution circulated in a copper electrorefining system, wherein a portion of the solution is withdrawn and recycled to the system after purification treatment. The purification treatment includes the addition of a hydrosulfide to the withdrawn solution to generate only the necessary quantity of hydrogen sulfide gas required in the reaction. The hydrogen sulfide gas generated is utilized for purification treatment. One process comprises dividing the solution withdrawn into two portions. Sodium hydrosulfide is added to the first portion to precipitate and separate metals as sulfides. Excess sodium hydrosulfide is further added to the first portion for reaction with residual sulfuric acid in the solution to generate hydrogen sulfide gas, then contacting the second divided portion with the hydrogen sulfide gas thus produced to precipitate and separate metals in the form of sulfides. The filtrate is then recycled to an electrorefining system.

  • Patent number: 5160552
    Abstract: This invention permits, in a colored galvanized coating using Ti-Zn, Mn-Zn, Ti-Mn-Zn, (Ti, Mn)-(Cu, Ni, Cr)-Zn, etc., to clearly and stably develop yellow, purple, green, blue or other color by controlling the composition of a galvanizing bath and oxidizing conditions. Further, a gold, dark red, olive gray and iridescence color which have not yet obtained can be developed. The color development effected by this invention is clearer than conventional. Instead of galvanizing, the spraying process may be adopted. The surface painting on the colored zinc coating is effective.

  • Patent number: 4702935
    Abstract: A production method for producing a high permeability alloy film which includes evaporating an alloy material composed of 1-6 wt % Al, 20-35 wt % Si, and the remainder of iron by irradiating the alloy with an electron beam, and then depositing the vapor from the alloy material onto a substrate for a predetermined time to produce an alloy film composition having a high permeability. The vapor deposition onto the substrate is preferably intercepted with the shutter until the concentration of aluminum of the vapor to be deposited has been decreased to a value between 20 and about 4 wt %.
