Abstract: In the dither current power supply control method, in order to prevent occurrence of a difference between the target average current and the detected average current, which is caused when a medium current (I0) between a dither large current (I2) and a dither small current (I1) and a waveform average (Ia) of the dither current are different from each other depending on a response time difference (a?b) between a rise time (b) and a fall time (a) of the dither current, negative feedback control is carried out by using a command medium current corresponding to the target average current corrected by a correction parameter based on experimentally measured data, thereby suppressing occurrence of a transient fluctuation error by the negative feedback control, so that a highly precise and stable load current is acquired.

Abstract: On one surface of a piece of wooden sheet, a cloth or paper is adhered to make an adhered sheet. An approximately V-shaped notch is provided on the adhered sheet, the adhered sheet is wetted to be softened, and a lubricant which acts to keep water is impregnated thereinto. Edge portions of the notch are overlapped, and the adhered sheet is tentatively molded in an approximately horn shape by a first hot press molding. The adhered sheet is then dried, impregnated with thermosetting resin, and half-dried. The adhered sheet is subject to a second hot press molding. A moisture-proof agent is applied on the adhered sheet, a center hole for a voice coil and periphery are removed to make a speaker diaphragm having a predetermined dimension and shape.

Abstract: A production method for an electroacoustic transducer diaphragm includes producing an adhered sheet by adhering a sheet member on a surface of a wooden sheet having a thickness of from 0.01 mm to 3 mm, and the sheet member being made of a material different from the wooden sheet, immersing the adhered sheet into one of a solution including 0.01-1 wt % of a penetrating agent and a solution including 0.01-1 wt % of penetrating agent and 0.01-20 wt % of a wetting agent, and molding the adhered sheet obtained by the immersing step so that the immersed adhered sheet has a predetermined shape of the electroacoustic transducer diaphragm.

Abstract: A transmission apparatus can perform a shift operation quickly without generating tooth contact and gear noise when shifting to a nonsynchronized gear train. The apparatus includes a first clutch; a first and a second input shaft; an output shaft; a planetary gear mechanism having a first and a second planetary gear train, a band brake and a direct clutch; a selection type gear train unit having a nonsynchronized gear train; a second rotation speed detector for detecting the rotation speed of the second input shaft as a second rotation speed; actuators; and a gear shift control part for controlling the actuators. When a request for shift to the nonsynchronized gear train is generated, the first clutch is released, the band brake is tightened, and the direct clutch is connected to reduce the second rotation speed. When the second rotation speed becomes equal to or less than a predetermined speed, a gear shift is executed.

Abstract: The purpose of this invention is to provide a water-based anti-fouling paint composition which has excellent anti-fouling effects in seawater and which has minimal effect on the environment and on the operators because organic solvents are essentially not included. The purpose is accomplished by providing a water-based anti-fouling paint composition that contains a metal cross-linked acrylic water-based emulsion composition containing a divalent metal compound and dithiocarbamate compound, and which essentially does not require volatile organic solvents.
