摘要: A step motor driving and control mechanism for use in an electronic timepiece for reducing the current consumption thereof is provided. Load detection circuitry detects the load condition of the step motor by detecting the signals induced in the drive coil of the step motor after each stepping of the rotor. The load detection circuitry selectively produces a load condition signal in response to detecting current peaks representative of a predetermined load condition of the step motor. The load detection circuitry is characterized by the use of MOS transistors therein for accurately detecting the occurrence of the current peaks. Driving and control circuitry is provided for receiving a low frequency timekeeping signal produced by a divider circuit and a load detection signal, when same is selectively produced by the load detection circuitry. In response to the presence or absence of a load detection signal applied thereto, the drive and control circuitry is adapted to vary the duration of the pulse width of a drive signal applied to the step motor to effect a driving of same.

摘要: A mobile image forming apparatus includes a body, a recording device supported by the body and configured to form an image on a recording medium, a roller provided to the body and configured to rotate on the recording medium while the body is moved in a scanning direction for image formation. The mobile image forming apparatus further includes a switching device configured to switch a state of the mobile image forming apparatus during image formation between a roller contact state in which the roller is in contact with the recording medium and a roller contactless state in which the roller is contactless with the recording medium.

摘要: In exemplary implementations of this invention, a shape controller controls the shape of a bladder as the bladder inflates. The shape controller includes a first set of regions and a second set of regions. The second set of regions is more flexible than the first set of regions. The shape controller is embedded within, or adjacent to, a wall of the bladder. When the bladder is inflated, the overall shape of the bladder bends in areas adjacent to the more flexible regions of the shape controller. For example, the shape controller may comprise paper and the more flexible regions may comprise creases in the paper. Or, for example, the more flexible regions may comprise notches or indentations. In some implementations of this invention, a multi-state shape display changes shape as it inflates, with additional bumps forming as pressure in the display increases.
