    • The invention has an object to provide a method for simulating power voltage distribution of a semiconductor integrated circuit, by which it is possible to attempt to shorten the time required for preparing a power unit model and it is possible to carry out a highly accurate simulation with uneven distribution of a floor plan taken into account. In Step S1, design information (Core size CS, core ring width CW, block shape BS, macro shape MS, block current BI, macro current MI, etc.) is inputted into a simulator. In Step S2, information regarding a floor plan (Block position BP, macro position MP, power I/O position IOP) is inputted into the simulator by a designer. In Step S3, the power unit management table is initialized, and resistance modeling and current source modeling are also carried out. In Step S5 (FIG. 1), the static IR drop is calculated based on the power unit management table CT obtained in Step S4.

    • A camera executes a photographing operation with multiple flashes. The camera includes a photometering unit and a control unit. The control unit controls light emission at a first electronic flash unit which is either built into or externally mounted at the camera and transmits a light signal constituting a preliminary light emission command to a second electronic flash unit provided separately from the camera by engaging the first electronic flash unit in light emission. The photometering unit photometers a subject when the second electronic flash unit executes a preliminary light emission. The control unit allows a photographing operation to be executed if a photometered value detected at the photometering unit is equal to or greater than a predetermined threshold value.

    • There is provided a vibration generator (40) in which a rotor with an unbalancer is rotated. The vibration generator includes a bottom plate (47) having a flat coil substrate (120) installed thereto, a stationary shaft (91) provided perpendicularly to the bottom plate, a magnet (85) installed on the stationary shaft (91) with a freely rotatable bearing being disposed between them and opposite to the surface of the flat coil substrate (120) with a slight clearance defined between them, and a weight (87) installed to the magnet (85). For generating a vibration, a current is supplied to the coil on the flat coil substrate (120) to rotate the magnet (85) and weight (87). The bottom plate (47) is formed from a nonmagnetic material. A thin magnetic plate (48) is installed at the side opposite to the magnet (85) with the bottom plate (47) being placed between the thin magnetic plate (48) and magnet (85).
