Abstract: A reproduction method includes a step of performing error correction of the first coded data piece and generating error location information which represents an error location of the first coded data; a step of generating erasure locator information which represents an erasure position of the second coded data piece, based on the error location information; and an erasure error correction step of performing erasure error correction of the second coded data piece based on the erasure locator information. The erasure locator information generation step includes the step of, when the error location information indicates that no error is detected in the Nth first symbol and the (N+2)th first symbol and that an error is detected in the (N+1)th first symbol, determining at least one of the plurality of second symbols provided adjacent to the (N+1)th first symbol as representing erasure.

Abstract: Water draining means (a water drain pipe and a water drain valve (54)) is provided that drains water out of a pot. A control device (80) makes the water draining means drain the water inside the pot when one of the following conditions is fulfilled: [1] the retention time counted by a first time counter (101a) has reached a predetermined time; [2] the total time, as counted by a second time counter (101b), that has elapsed after the water started to be fed has reached a predetermined time; [3] the total amount of water, as detected by a fed water amount detector (102), that has been fed into the pot has reached a predetermined amount; [4] the total water feed time, as counted by a third time counter (101c), for which the water has been fed into the pot has reached a predetermined time; and [5] an instruction to drain the water is entered via an operation panel (13).

Abstract: A heat-cooking apparatus includes blowing means (100) that blows cooling air to an opening (20a) of a heating chamber (20) when a door (11) is opened after steam is supplied to the heating chamber (20) for preparatory operation before heat-cooking or for heat-cooking itself. More specifically, after steam is supplied to the heating chamber (20), when the door (11) is opened, the blowing means (100) drives a conventionally existing cooling fan (101) to suck in cooling air from outside the apparatus, and deflects the cooling air toward the opening (20a) of the heating chamber (20) with a decoration box (102) so that the cooling air is blown to the opening (20a) so as to pass sideways substantially across it. Thus, the cooling air mixes with high-temperature steam that tends to overflow frontward as soon as the door (11) is opened, and thereby lowers the temperature of the steam. This surely prevents the user from being hurt, as by being burnt, with the overflowing steam.

Abstract: A multi-layered information recording medium including a plurality of recording layers, the multi-layered information recording medium comprising: a user data area for recording user data; and a plurality of spare areas including at least one replacement region, wherein when the user data area includes at least one defect region, the at least one replacement region may be used in place of the at least one defect region, wherein a first spare area of the plurality of spare areas is positioned so as to be contiguous to a first user data area of a first recording layer, a second spare area of the plurality of spare areas is positioned so as to be contiguous to a second user data area of a second recording layer, and the first spare area and the second spare area are positioned approximately at the same radial position on the multi-layered information recording medium.

Abstract: A high-frequency heating apparatus comprises a heating chamber, a high-frequency generator, a waveguide, an antenna, a motor for rotating the antenna, and a stage (6) provided above and near the antenna to partition the heating chamber and made of dielectric. A rotary base on which an object to be heated is mounted is provided on the stage. A first magnet is provided to the antenna. A second magnet is provided on the rotary base at a place corresponding to the first magnet on the rotary base. By utilizing the magnetic coupling between the first and second magnets, the rotary base is rotated in synchronism with the rotation of the antenna. While maintaining the advantages of conventional antenna high-frequency heating apparatuses, the heating efficiency by grill heating or oven heating is enhanced, and minute heating uniformness is achieved.

Abstract: Data is read from a recording medium and the reproduced data is deinterleaved and stored to a first memory while input/output to/from the first memory is arbitrated. It is determined whether a predetermined number of data units is stored to the first memory. Based on the result data, it is determined whether transfer of the data stored in first memory to a second memory is permitted. If data transfer is permitted, the reproduced data is transferred from the first memory to the second memory, during which time input/output to/from the second memory is arbitrated. The reproduced data stored to the second memory is then error corrected, and user data contained in the error corrected reproduction data is externally output from the second memory.

Abstract: A cooker has an external circulation path outside a heating chamber in which foods are to be placed. A blower sucks in gas inside the heating chamber, and forms, in the external circulation path, a gas flow that makes the sucked gas return to the heating chamber. Downstream of the blower, the external circulation path is provided with an exhaust port, in which a damper is provided. The damper closes the exhaust port during cooking, and opens the exhaust port when a door of the heating chamber is opened. After the damper is changed to a position of opening the exhaust port, the blower continues to operate until a predetermined condition is satisfied.
