Title: Information recording device
Inventor: KURIKI YOSHIAKI
IPC: G11B11/10
Filed: 1998-12-24
Abstract: PROBLEM TO BE SOLVED: To reduce the frequency in which noise incidental to a large movement of a head is recorded on a recording medium, by detecting an area in which time recordable continuously in the medium is longer than a prescribed time and by controlling so as perform recording in the detected area. SOLUTION: First, the recording/reproducing part 5 reproduces management information recorded in the management area from a magneto-optical disk 6 and transmits it to the control part 3. The control part 3, on the basis of the management information received, recognizes the recordable area of a disk. Next, if the input picture data are animation data and if an animation recordable area exists in the recognized recordable area, all animation recordable areas are specified as areas for recording the data, and then, a recording start command is transmitted to the recording/reproducing part 5. If the input picture data are still picture data, all recordable areas are specified as areas for recording the data, and then, the recording start command is transmitted to the recording/reproducing part 5.

Title: Viterbi decoder and viterbi decoding method
Inventor: HAYAMIZU ATSUSHI
IPC: H03M13/41
Filed: 1999-12-24
Abstract: PROBLEM TO BE SOLVED: To solve a problem of a conventional Viterbi decoder that it cannot maintain excellent recording performance on the occurrence of unarranged shapes of recording marks due to a medium characteristic and nonlinear distortion in a reproduced waveform when data recorded on a recording medium are reproduced by using a Viterbi algorithm. SOLUTION: A data estimate circuit 14 outputs estimated data resulting from estimating input data at a point of time before a prescribed bit period from present input data on the basis of a decoded data sequence outputted from a path memory 12. An object value arithmetic circuit 15 corrects the object value by using a difference between the estimated data and the present input data for an object error and outputs 1st object values that are obtained to a branch metric arithmetic circuit 11 as a plurality of object values. Since the branch metric arithmetic circuit 11 can execute the branch metric arithmetic operation on the basis of a plurality of the 1st object values close to a plurality of mean values with the highest incidence frequency (a peak in a histogram), the decoding performance can be enhanced more than the use of a fixed object value.

Title: Air duct
Inventor: IMURA HITOSHI
IPC: B60S1/54
Filed: 1997-12-26
Abstract: PROBLEM TO BE SOLVED: To compensate for decrease in the volume of air flowing through a duct by providing a gap between a throat formed by drawing an upstream side duct tubularly and a large diameter downstream side duct covering the throat. SOLUTION: An upstream side duct 1 is drawn tubularly to form a throat 2 being inserted into a downstream side duct 4. A gap 5 is formed between the throat 2 and a large diameter duct 4 covering it in order to conduct between the inside of the duct and the outdoor air. A cone part 3 is tapered as gently as possible. During a process where the outdoor air from the upstream side duct 1 passes through the cone part 3 thence through the throat 2, pressure energy of fluid is converted partially into kinetic energy to produce sucking action and the pressure in a suction chamber R is reduced. Consequently, the outdoor air is sucked through the gap 5. The air volume Q1 of the upstream side duct 1 is added with the air volume Q2 from the gap 5 and the air volume Q3 of the downstream side duct 4 is increased to Q1 +Q2 .
