A guide groove is formed without wobbles. The guide groove is periodically modulated with its width. Encrypted data are recorded with marks formed on the record film along the guide groove. Information recorded by periodically modulating the guide groove with its width can be accurately detected by a band pass filter. Thus, rotation control information and address information can be stably reproduced. In addition, since the guide groove is formed without wobbles, a drive device having a pirated disc determination mechanism can reproduce encrypted content as with a ROM disc.

There is provided an optical modeling apparatus that forms a model of a desired shape by sequentially forming hardened layers by irradiating a light curable resin with light. The apparatus includes a first light source that emits a light beam for plotting on the resin, a scanning device that scans the light beam from the first light source over the resin, a second light source that emits light that irradiates one fixed region of the resin at a time, a spatial light modulator that spatially modulates the light from the second light source and blanket-exposes a specified region of the resin, and an exposure position adjuster that moves, in at least one direction, the light from the spatial light modulator. The light beam from the scanning device and the light from the spatial light modulator form each hardened layer.

A soundproof type engine generator has a first external air inlet and a second external air inlet formed on a soundproof case K. A first cooling passage guides external air drawn in through the first external air inlet through a duct to a first fan, then from the first fan to a generator and discharges the air out of the soundproof case K. A second cooling passage guides external air drawn in through the second external air inlet to an engine using a second fan and then discharges the air out of the soundproof case The first fan is made up of a disk-like planar part, a plurality of first blades and a plurality of second blades, respectively provided radially on both head and tail sides of the planar part. External air drawn with the plurality of first blades through the first external air inlet is guided through the duct to the generator, and discharged out of the soundproof case. Air in the soundproof case is discharged with the plurality of second blades out of the soundproof case. The soundproof type engine generator effectively cools the interior of the soundproof case and simplifies the constitution of the air feed passage via the layout and configuration of the fan.

A power generating apparatus includes an engine for driving a generator, a muffler cover for covering a muffler for exhaust supplied from the engine from an external side of the muffler, a fuel tank for storing fuel to be supplied to the engine, and a canister containing an adsorbent for adsorbing thereonto fuel that evaporates from the fuel tank. The canister includes a communicating tube, which places the canister in communication with the atmosphere. The canister is also in communication with an intake system of the engine. The communicating tube of the canister has its opening at a position near to the muffler as well as to an inner surface, on the side of the muffler, of the muffler cover, to improve the purge characteristics of the adsorbent so that the usable live of the adsorbent is increased.

A power generating apparatus includes an engine for driving a generator; a fuel tank for storing fuel to be supplied to the engine therein, and a canister containing an adsorbent for adsorbing thereonto fuel that evaporates from the fuel tank to inhibit release of the fuel vapor into the atmosphere. The canister includes a communicating tube, which places the canister in communication with the atmosphere. The canister is in communication with an intake system of the engine. The canister is positioned proximate an exhaust system of the engine to improve the purge characteristics of the adsorbent so that a usable life of the adsorbent is increased.

It is an object of the present invention to reduce a burden on a maintenance terminal of a storage control system. A storage control system 13 includes one or more operation information storages 59 in which operation information of the storage control system 13 is stored. Among plural DKAs 43 in the storage control system 13, a representative DKA 43D connected to the operation information storage 59 reads out operation information stored in an SM 39 and stores the operation information in the operation information storage 59. The operation information stored in the operation information storage 59 is outputted to an SVP 11 in a form in which the operation information is not stored in an HDD 7 of the SVP 11.

In a disk array system having a plurality of spare drives, the storage areas of which are not wasted without being influenced by the physical boundaries thereof. There is defined one large spare parity group 104 which is composed of a plurality of spare drives 103, 103, . . . , and so on. A spare logic drive 202 having the same capacity as that of a faulty data drive 101B is cut out from a large spare logic drive 201 provided by the spare parity group 104, and the data of the faulty data drive 101B are copied to the cut spare logic drive 202. A virtual physical drive 206 corresponding to the spare logic drive 202 is defined and is incorporated instead of the faulty data drive 101B into a data parity group 102A. As a result, data of the faulty data drive 101B are saved in the virtual physical drive 206 (or the spare logic drive 202).
摘要:
An image forming device and a color misregistration correction method allow for stable formation of excellent images with little color misregistration. A reference patch image is formed on a reference photosensitive drum 3, and transferred to a transfer belt 7. A correction patch image is formed on a correction-target photosensitive drum 3, and transferred onto the reference patch image by superimposition. A registration detecting sensor 21 detects a density average value of the reference patch image and the correction patch image. Based on the density average value, a correction value for controlling the correction-target photosensitive drum 3 is calculated, and rotational phase control is performed in accordance with the correction value.
