Title: Recording and reproducing method for digital signal
Inventor: NIKI MAMORU
IPC: G11B20/12
Filed: 1988-12-14
Abstract: PURPOSE:To prevent the sound quality of a reproducing audio signal from deteriorating by mixing an audio signal and a video signal based on a current voice format at the time of performing the recording and reproduction of both signals simultaneously. CONSTITUTION:The audio signal So and the video signal Sv are mixed by conforming to the current voice format by a mixing means 20. In such a case, the number of quantization in the audio signal So is reduced, for example, from the current constitution of 16 bits of constitution of 10 bits, however, deterioration in the sound quality according to the reduction of the number of quantization scarcely occurs. Also, since a video is still picture, it is enough to perform quantization of six bits. In the case of regenerating a digital signal DS in which the audio signal So and the video signal Sv are mixed by a current digital-audio tape recorder 10, no influence when a digital video signal DSv is regenerated as a digital audio signal DSo on the audio signal So is given. In such a manner, it is possible to prevent the deterioration in the regenerating quality of the audio signal from occurring.

Title: Bus power unit for mounting on artificial satellite and method for controlling shunt current
Inventor: MURAMATSU TAKESHI
IPC: H02J1/00
Filed: 1997-11-18
Abstract: PROBLEM TO BE SOLVED: To reduce calorific value of a shunt circuit which controls a shunt current consuming part excessive of an electric power generated from a solar battery, by controlling the shunt current by using a pulse width controlling switching regulator constant-current control circuit to the shunt circuit. SOLUTION: When a bus voltage 103 is higher than a specific voltage value, a bus voltage error detecting circuit 5 detects the error of the bus voltage 103 and outputs a bus voltage error detecting signal 101. Then a control circuit outputs a pulse signal having the pulse width corresponding to the signal 101 and generates a shunt current 102 while the control circuit is controlled by means of a switching regulator 3. The power loss P of the shunt current 10 is expressed by the product (P=Von×Ix×D) of conductingtime voltage drop Von of a switching element, maximum current Ix (switching peak current) of a solar battery 2, and duty ratio D of the conducting time.  Therefore, the power loss of a DC control bus power unit for mounting on an artificial satellite becomes smaller as compared with the product of the output voltage of the solar battery and shunt current, because the voltage drop Von is usually a small value of about 1 V or lower.
