Abstract: A method and an apparatus for operating a displayed area of an electronic map and a recording medium are provided. In the method, a displayed area of an electronic map is displayed first. Then, an indicating object of a point of interest (POI) located outside the displayed area is displayed on an edge of the displayed area towards a direction of the POI with respect to the displayed area. When the indicating object of the POI is selected, the displayed area of the electronic map is changed to the displayed area comprising the POI. Accordingly, users are able to quickly change the displayed area and check a location and related information of each POI in a simple operation manner.

Abstract: The present invention provides a disassembling tool including a cylinder and a clamping assembly. The cylinder includes two ear members, two pivoting holes, a casing hole and an opening. The clamping assembly includes two pulling arms and a clamping arm. The two pulling arms have a linking relation with the clamping arm. The clamping arm has a teeth section, used for increasing a fixing ability of the clamping arm. After fixing the tie rod in the cylinder, the two pulling arms drive the clamping arm pivot with respect to the pivoting hole. When the clamping arm pivots, the teeth section of the clamping arm clamps the tie rod, forcing the tie rod to rotate and become loosened. Because the clamping arm can completely pivot over the casing hole, the disassembling tool can easily disassemble not only tie rods with various sizes, but tie rods with even smaller sizes.

Abstract: The present invention provides a wheel cylinder spreader including a main body, a rod, a holding portion, and a control portion. An elongated toothed element is formed on the rod, and a leaning element is disposed on the holding portion. The holding portion can drive the rod to move due to the attachment of the leaning element and the elongated toothed element. Because the contact area of the elongated toothed element and the leaning element is larger and the transmission of force is more direct, the frequency of squeezing the holding portion is decreased and the driving efficiency is promoted. Also, the slipping and the abrasion of the elongated toothed element and the leaning element are prevented. Otherwise, when the rod is not leant by the control portion, the rod tends to move toward a specific direction due to a reposition elastic element.

Abstract: A model airplane may include a fuselage, a wing rib removably attached at a top portion of the fuselage, and a wing having two wing sections. Each of the two wing sections may include an opening at an exterior end. The model airplane may also include a connecting member removably coupled with the fuselage alternatively either at the wing rib or at a side portion of the fuselage. The connecting member may be removably inserted into the opening of a wing section to couple the wing section with the fuselage. The connecting member may include a ferromagnetic material which is magnetically attracted to a ferromagnetic material included at an end of the opening within the wing section when the connecting member is inserted into the opening to couple the wing section with the fuselage.

Abstract: An ocean water drawing system includes: a well; a working tunnel disposed underground and having an end segment distal from the well; a pipeline unit including a primary pipeline disposed in the working tunnel, and having one end extending sealingly into the well and the other end extending through the end segment of the working tunnel and into an ocean so as to permit ocean water to flow into the well through the primary pipeline; and an access tunnel isolated from the well and extending downwardly from a ground surface to intersect the working tunnel so as to communicate spatially with the working tunnel and so as to permit access into the end segment of the working tunnel for operation and maintenance of the primary pipeline.

Abstract: A dust meter includes a duct member having a lower portion formed with an air inlet, and an upper portion formed with an air outlet, and confining an air passage. A heating element is used to heat air in the air passage to result in air flow from the air inlet to the air outlet. A light emitter is operable so as to generate a light beam in the air passage. An optical sensor module includes a light sensor responsive to changes in optical flux in the air passage attributed to dust content of the air that flows from the air inlet to the air outlet. The sensor module generates an electrical signal that varies with the optical flux detected by the light sensor. A processing circuit determines an actual ambient dust concentration by referring the electrical signal from the sensor module to pre-established data in the processing circuit.
