摘要:
An optical disc recording method of suppressing variations in the record quality due to variations in an initial strategy of a write strategy using many parameters corresponding to a next-generation large-capacity optical disc. Modulation conditions for recorded data on the optical disc are determined based on a real measurement thereof; an initial strategy that meets the modulation conditions is determined; an optical strategy is determined in which the record quality is best in the vicinity of the initial strategy; and data is recorded on the optical disc, using the optimal strategy.

In a multi-blade centrifugal fan in which an impeller is provided in a scroll casing in a freely rotatable manner, the scroll casing is provided with an axially expanded portion that forms an air channel at a bottom surface thereof which is expanded in a rotation-axis direction at a radially outer side of an annular flange portion which supports the impeller; and is provided, in a region of an outlet between a tongue portion and a spiral-end portion of the scroll casing in the axially expanded portion, with a protrusion that protrudes radially outward from a radially inner side surface by a predetermined amount so as to directly face an airflow in a circumferential direction.

An inductance device comprises a magnetic core, a coil a conductor and a dielectric member. The coil is made of turns of insulated conductive wire. The conductor is distinct from the coil and is insulated from the magnetic core. The dielectric member is disposed between the conductor and the coil. The dielectric member, the conductor and the coil constitute a capacitor. The inductance device is used in, for example, a filter device or a noise filter.

Provided is an etching method capable of increasing a selectivity of a polysilicon film with respect to a silicon oxide film and suppressing the formation of recesses in a silicon base material. A wafer includes a gate oxide film, a polysilicon film and a hard mask film having an opening sequentially formed on a silicon base material, and has a native oxide film in a trench of the polysilicon film corresponding to the opening formed thereon. The native oxide film is etched, so that the polysilicon film is exposed at a bottom portion of the trench. An ambient pressure is set to be 13.3 Pa, and O2 gas, HBr gas and Ar gas are supplied to a processing space, and a frequency of bias voltage is set to be 13.56 MHz, so that the polysilicon film is etched by the plasma generated from the HBr gas to be completely removed.

A computer system boots the system from a bootup-memory-image stored in a nonvolatile memory unit forming part of a main memory device. When the first write access occurs after system operation, the system copies the data of a block of the bootup-memory-image to a readable/writable main memory unit forming another part of the main memory device for each block of the bootup-memory image. The system performs write operation on the copy, and subsequently switches access to an area of the bootup-memory-image to which data has already been copied to access to the copy. A bootup method for a computer system and program recording medium are also disclosed.
