Patent JP-H1125572-A (JP)
Title: Optical disk player
Inventor: NIKAIDO MASATAKA
IPC: G11B20/10
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To avoid omission of a consonant even when a frame is reproduced at a high speed and to maintain clearness by daring to reproduce the frame which corresponds to a frame to be discarded by thinned-out processing based on the predetermined length of a frame to be detected in the case of detecting the frame having a radical signal level change as compared with the precedent and successive frames. SOLUTION: In the case of highly speedily reproducing an audio signal from an optical disk 1 recording compressed frame information, plural frames are thinned out of continuous frames at an approximately constant rate by a system control part 12. When a short block size as block size information comprised in the compressed information is detected by a consonant discriminating part 9, the prescribed number of the compressed frames after the above compressed frame are transferred to a compander part 10 without being thinned out and are reproduced. Consequently, a consonant part in voice recording or a impact sound part such as a piano, etc. in music recording is maintained and hence the clearness and the quality of a sound can well be maintained.

Title: Trace system
Inventor: HASHINAKA KOJI
IPC: G06F13/00
Filed: 1987-07-20
Abstract: PURPOSE:To detect a specific area where an interruption is produced by adding a trace permitting circuit to instruct a tracing action to a gate when a signal showing the coincidence between the bus signal value and the trace conditions is received. CONSTITUTION:A decoding circuit 14 checks whether the bus signal value is coincident with the trace conditions or not when a specific signal, e.g., a fetch signal is outputted. When noncoincidence is obtained, this fact is informed to a trace permitting circuit 15. While a fact showing the coincidence is also informed to the circuit 15. The circuit 15 inhibits the tracing actions to a gate 16 when a data strobe signal DS is produced when the noncoincidence between the bus signal value and the trace conditions is informed. Then the circuit 15 gives an instruction to the gate 16 for tracing actions when the coincidence between said signal value and conditions is informed. Thus it is possible to know a specific area where an interruption is produced.

Title: Method for discriminating voiced section
Inventor: ONO MANABU
IPC: G10L15/04
Filed: 1990-07-09
Abstract: PURPOSE:To make a voiced section decidable even when the noise power of input signals is large by comparing the power of predictive residuals with a preset 1st threshold value and the power of the input signal in a decision frame with a 3rd threshold value. CONSTITUTION:The predictive residuals of a decision frame are found by using a voiceless prediction coefficient found from past plural voiceless frames. As a result, the power of the predictive residuals of the decision frame can be obtained by subtracting the noise power from the power of the input signal in the decision frame. Then the power of the predictive residuals excluding the noise of the small section of the decision frame is compared with the 1st threshold and, at the same time, the power of the input signal in the small section of the decision frame is compared with the 2nd and 3rd threshold. Therefore, a decision frame is decided as a voiced section if the section contains a voice even it is very low and only a decision frame which does not contain any voice not only in its own frame, but also in preceding several frames, can be decided as a voiceless section even when the noise power is large.

Title: Bottom electrode of dc electric furnace and its manufacture
Inventor: OGINO NAOHIKO
IPC: H05B7/06
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To prevent local heating due to a current concentration, to prolong an electrode using period and to facilitate a maintenance by installing a solid electrode made of a composite material obtained by filling a magnesia refractory material as an aggregate with an iron-based alloy as a matrix at a bottom of a DC electric furnace. SOLUTION: An anode is made of an iron-base alloy 10 as a matrix and obtained by filling an MgO aggregate 11 as a refractory material. In this case, since an area occupying the alloy is relatively large, its self-heating due to an electrode concentration is prevented, thereby preventing local fusing. Since the alloy 10 is eroded as number of times of charging is increased but a steel of a residue of molten steel compensates it, its lifetime can be prolonged. In the case of a conventional magnesia carbon electrode, a molten steel component is retained on a surface of a furnace bottom so as to disturb an adherence of the magnesia carbon, but by such a this electrode structure, an eroded portion is supplemented by the dissolved iron component retained at the bottom.
