  • Patent number: 10677413
    Abstract: In a lighting device adapted to be mounted on a vehicle, a PTC (positive temperature coefficient) thermistor (535), a first fixed resistor (R1), and a first light emitting element (531) are connected in series with a voltage source. A heat conduction suppressor (7) is configured to suppress heat conduction from the first fixed resistor (R1) to the PTC thermistor (535).

  • Patent number: 10556281
    Abstract: To keep an electrode guide from interfering with an object such as a workpiece during the workpiece processing period, in the present invention, a path-generating device of an electrical discharge machine that is provided with an electrode guide for supporting a rod-shaped electrode is configured so as to be equipped with: a shape data-reading unit for reading the initial shape of the workpiece prior to processing and a target shape of the workpiece; an electrode-path-generating section or generating an electrode path for moving the electrode laterally on the basis of the target shape of the workpiece; and a guide path-generating section for generating an electrode guide path, which avoids interference between the electrode guide and the workpiece, on the basis of the initial shape of the workpiece.

  • Patent number: 10252192
    Abstract: A filter medium includes: a core yarn and a binder yarn twisted together, at least one of the core yarn or the binder yarn being weldable; and a filament yarn being fuzzy and weldable, the filament yarn being welded to at least one of the core yarn or the binder yarn while being placed between the core yarn and the binder yarn as twisted together. A filtering device for filtering a liquid to be treated with a filter medium layer includes the filter medium. A method of manufacturing the filter medium is also disclosed.

  • Patent number: 9718004
    Abstract: A filter medium layer includes filter media configured to capture suspended solids contained in a liquid to be treated and filtering aids configured to allow the suspended solids contained in the liquid to be treated to pass through the filtering aids. The filter media and the filtering aids are mixed together and the liquid to be treated is filtered by being passed through the filter media and the filtering aids as mixed together. A filter device includes the filter medium layer and a filter tank configured to accommodate the filter medium layer.

  • Patent number: 6461507
    Abstract: A continuous compression-type dewatering apparatus has a filter chamber (3), a drive shaft (17), a vane (15), and a supply path (50). The filter chamber (3) is delineated by an annular plate (2) and two side plates (1, 1). The drive shaft (17) passes through the center axis of the annular plate (2) and through the inside of the filter chamber (3), and is free to rotate with respect to the filter chamber (3). The vane (15) is disposed within the filter chamber (3), is fixed with respect to the drive shaft (17), and rotates in concert with the drive shaft (17). The supply path (50) passes through the drive shaft (17) and supplies raw fluid to the filter chamber (3). The vane (15) as two side edges (15a, 15a) facing the side plates (1, 1) and an end edge (15b) facing the annular plate (2). The side plates (1, 1) include a screen (4) for separating the raw fluid into a filtered fluid and a cake. The annular plate (2) includes an ejection port (7) for the cake.
