Title: Feedback clamping device
Inventor: SAKURAI HIROSHI
IPC: H03M1/66
Filed: 1989-08-22
Abstract: PURPOSE:To obtain a video signal with high resolution even when an ambient temperature is changed by fixing the black level of a video signal by applying feedback in DC fashion from a video output circuit to a video input stage. CONSTITUTION:The video signal amplified with transistors(TR) Q1 and Q2 drives a CRT with TRs Q3 and Q4. The output of the TR Q1 is supplied to an A/D converter 4 via a buffer amplifier 5. Bias change by the temperature drift of the TRs Q1 and Q2 is detected between the input terminals of a reference voltage and the A/D converter 4. A detection value, after being converted to a digital signal fractionated with the A/D converter 4, supplies a DC voltage converted to an analog voltage with a D/A converter 3 to the other side of an operational amplifier 1 similarly as a black level, thereby, the bias change due to the temperature drift of the transistors Q1 and Q2 can be eliminated.

Title: Magnetic disk device
Inventor: TAKAHASHI HARUHIDE
IPC: G11B33/14
Filed: 1990-08-22
Abstract: PURPOSE:To more actively collect dust floating in air in a head assembly and to reduce the dust floating in the air by forming a means for collecting dust on the whole surface or a part of the surface of the inside of a casing for the head disk assembly. CONSTITUTION:The means for collecting dust is formed at least on a part of the inside of the casing 3 of the head disk assembly.

Filed: 1990-08-20
Abstract: PURPOSE:To obtain a beautiful sound of chords without fluctuations in the frequency of a melody sound by detecting the melody sound together with chords and correcting the frequency of the chords according to the frequency of the melody sound. CONSTITUTION:A chord detecting means detects the chords consisting of plural pitches specified by a pitch specifying means and a melody sound detecting means detects the melody sound from the input plural pitches. The frequencies of other chord constituent sounds are corrected to a good-sound rhythm of a pure rhythm according to the detected melody sound. In this case, a frequency correcting means may be a means which corrects all the chord constituent sounds to the rhythm such as the pure rhythm. Further, a means which corrects only three-degree sounds of the chords is usable. Thus, the frequencies of the chord constituent sounds are corrected according to the frequency of the melody sound to eliminate fluctuations in the pitch of the melody, thereby improving the sound of chords.
