A dot matrix display system for multiple-tone displays, including a display device in which pixels are arrayed in a matrix shape, an LC (liquid-crystal) drive signal generator which converts color display data into LC display data, an 8-level data driver which selects one of 8-level voltages in accordance with the LC display data and then delivers the selected voltage, and an 8-level applied LC voltage generator by which the 8-level voltages to be applied to the pixels are produced so as to substantially make uniform color differences between the respectively adjacent tones of the multiple-tone displays. Owing to the substantially uniform color differences between the respectively adjacent tones, multiple-tone displays which are uniformly seen by the human eye can be obtained.

Embodiments in accordance with the present invention provide a connector for a data storage device having a sufficient strength, and relate to a data storage device using such a connector. In accordance with one embodiment, a data storage device is provided having a circuit board and a connector for making a connection with an external interface. The connector includes bosses disposed on both sides across a center of a direction orthogonal to a direction perpendicular to a main surface of the circuit board and a direction, in which the connector is connected to the interface. The boss is a protrusion that counteracts a force applied to the connector by being embedded in a hole disposed in the circuit board when the connector is disposed in the circuit board. The boss has an oblong shape having a length in a direction, in which the interface and the connector are connected together, longer than a length in a direction orthogonal to a direction perpendicular to a main surface of the circuit board and a direction, in which the connector is connected to the interface. The boss protrudes in the direction perpendicular to the main surface of the circuit board.

Damage of a connection between a connector and a circuit board on which the connector is mounted is to be prevented at the time of connecting the connector with a corresponding connector on a host side. In one embodiment, an HDD is provided with a serial ATA connector. The connector is mounted on a circuit board. The HDD is also provided with stiffeners for fixing the connector to the circuit board. When the connector moves toward a base at the time of connection thereof to a host-side connector, the stiffeners come into abutment against the base to stop the movement of the connector. As a result, damage of the connection between the connector and the circuit board can be prevented.

A liquid crystal halftone display system including a tone generator which, for pixels having P tones of K tones (1≦P≦K), alternately outputs first N-bit tone display data and second N-bit tone display data in successive frames at one of a first phase and a second phase. Within a block of pixels, the tone generator alternately inverts the phase of the N-bit tone display data at successive first pixels having different ones of the P tones within the block of pixels beginning at a left side of the block of pixels, and alternately inverts the phase of the N-bit tone display data at successive pixels having a same one of the P tones within the block of pixels beginning at the left side of the block of pixels.

摘要:
An inertial latch for preventing an actuator arm, which is a component of a disk apparatus, from flying out from an unloading position because of an external shock. The actuator arm cannot be prevented from flying out from the unloading position because of repulsion produced when the actuator arm crashes against a stopper, by operation other than an external shock. A latch, for engaging with a point end portion of the actuator arm to prevent the actuator arm from flying out, is provided with a sensing protrusion 16e. When the actuator arm crashes against an outer crash stop, the shock causes the latch to rotate and engage with the actuator arm, whereby the actuator arm is prevented from flying out.
