An optical pickup includes a light emitting device, a prism, and an objective lens. The light emitting device emits a laser beam. The prism has an entrance face and an exit face. In the prism, the laser beam emitted from the light emitting device is perpendicularly incident on the entrance face, is parallel-shifted, is perpendicularly reflected, and is emerged from the exit face. The objective lens focuses the laser beam emerged from the prism on a recording surface of an optical disk.

An A.C. generator has a rotor that is equipped with a permanent magnet and a field coil. The output of the A.C. generator charges the high-voltage battery. Voltage of the high-voltage battery is stepped-down by a DC/DC converter and supplied to the low-voltage battery. When the motor controller detects that the field coil has not been energized, the higher-rank controller switches so as to generate power by means of the permanent magnet of the A.C. generator and charge the low-voltage battery. This mechanism enables power to be generated when a circuit malfunctions.Thereby, a power supply system for vehicle can generate power when a circuit malfunctions so that the driver on the vehicle can drive the vehicle to a repair shop.

An object of the present invention is to provide a semiconductor memory device suitable for larger-capacity storage because of its ability to store 3 or more bits in one element and capable of a high-speed and high-efficiency write operation due to a reduced leakage current during the write operation and provide a fabrication method therefor. According to the present invention, each of elements has a source region, a drain region, a control gate, two charge storage regions, and one or more assist gates. During a write operation, source side injection writing is performed with respect to a write target element by using the assist gates, while adjacent elements are isolated by field isolation using the assist gates.

The present invention provides a method for preparing an ink-jet recording sheet including a support and a colorant receiving layer disposed on the surface of the support, and an ink-jet recording sheet prepared by the method. The method including: coating a coating solution including inorganic fine particles, a water-soluble resin and a boron compound on the surface of the support to form a coated layer; and cross-linking and hardening the coated layer to form a colorant receiving layer. The cross-linking and hardening is performed by applying a solution containing a metal compound and having a pH of 8 or higher to the coated layer or a coated film at one of: (1) simultaneous as coating the coating solution; (2) during drying of the coated layer and before the coated layer shows a falling rate of drying; or (3) after the coated layer is dried to form the coated film.
