    Abstract: A loudspeaker unit includes a voice coil, a diaphragm, a damper, a frame supporting an outer edge of the diaphragm and an outer edge of the damper, and a duct projecting from an outer surface of the frame, with air moved by vibration of the diaphragm flowing into and out of the loudspeaker unit through the duct. The frame has an aperture that communicates with a space inside the frame. The duct, serving as a separate member, is attached to the frame so as to cover the aperture. The frame further includes a support tab that projects into the aperture. Link terminals are attached to the support tab. Before the duct is attached to the frame, lead wires extending from the voice coil are formed into a predetermined shape and are then connected to the link terminals in a space within the aperture.

  • Publication number: 20140357171
    Abstract: A method of manufacturing a grinding wheel, and a grinding wheel. After a first overcoat layer is formed on each of CBN abrasive grains, a second overcoat layer that is plastically deformed under a pressure lower than a pressure under which the first overcoat layer is deformed, is formed on the outer side of the first overcoat layer to manufacture coated abrasive grains. The coated abrasive grains are subjected to pressure-molding to be formed into a prescribed shape under a pressure that is equal to or higher than a pressure under which the second overcoat layer is plastically deformed. The second overcoat layers are deformed and flow to form a molded material having a structure in which the first overcoat layers contact each other, and the flowing second overcoat layers are moved into clearances between the coated abrasive grains.

  • Publication number: 20140283597
    Abstract: To detect humidity, used are a first series connection circuit connecting a thermistor and a fixed resistor via a node, a second series connection circuit connecting a resistance change type humidity sensor and the thermistor via the node, and a third series connection circuit connecting the humidity sensor and the fixed resistor via the node. A predetermined voltage is applied across the first circuit to detect a first voltage indicating temperature through the node, and secondly across the second circuit to detect a second voltage indicating a first humidity through the node, and finally across the third circuit to detect a third voltage indicating a second humidity through the node. Then, the first voltage is compared with a reference voltage and judgment is made, based on a comparison result, to determine which of the second voltage and the third voltage is relevant to use as a basis for outputting the humidity as detected.
