Filed: 1985-10-04
Abstract: PURPOSE:To stabilize multi-value information conversion by connecting a circuit peak-holding each high/low level of a picture signal to each high/low reference level terminal of an A/D converter. CONSTITUTION:A high level peak of a picture signal Si outputted from a picture processing circuit 4 is held by a high level peak holding circuit 10 and given to an A/D conversion circuit 1 as a high level reference value VH. Further, a low level peak of the picture signal Si is held by a low level peak hold circuit 11 and given to the A/D converting circuit 1 as a low level reference value VL. On the other hand, a picture signal is delayed by a delay circuit 12 by a signal processing time in the high level peak holding circuit 10 and the low level peak holding circuit 11 and the result is inputted to the A/D converter 1. Thus, the reference voltage of the A/D converter 1 follows the level of the picture signal Si and follows the background level fluctuation of the picture information, then the multi-value information conversion by the A/D conversion circuit 1 is made stable.

Abstract: PURPOSE:To attain low power voltage configuration by converting 2 emitter coupled logic circuit(ECL) inputs into 4 levels and taking AND logic by the comparison. CONSTITUTION:The circuit is constituted of inverter & level shift sections 1, 1, ECL threshold level generating sections 1, 2, and comparison output sections 1, 3. Then two ECL logic inputs are converted into two kinds of different logic levels (H, L)1=(L1, L3), (H, L)2=(L, H2) respectively in the relation of L1>L2>L3>L4, inversion logic is adopted for the inputs converted into the logic level (H, L)1 and the quantity is compared with the input converted into the other logic level (H, L)2. Only when the both two inputs are at H, the relation of (H, L)2>(H, L)1 is satisfied and an AND output reaches an H level. Thus, the 2-input ECL AND circuit with high speed and low power consumption operated at the low voltage of 3V or below is obtained.

Title: Disk loading device
Inventor: SUZUKI NOBUHIRO
IPC: G11B19/12
Filed: 1989-08-30
Abstract: PURPOSE:To shorten time until a start to read the information of a disk by sending out a driving signal to a tray driving device by a disk loading detection signal from a disk detecting means. CONSTITUTION:When the disk is loaded on a tray 1, such a state is detected by disk detectors S1-S5 and a signal is sent out to a control circuit 3. The control circuit 3 receiving this signal drives a tray driving device 8 and starts to pull-in the tray 1. The size of the disk to be loaded on the tray 1 is detected by the disk detecting means S1-S5 and a signal is sent out to the control circuit 3. The control circuit 3 drives a pickup driving device 9 and sends out a signal so that a pickup can be moved to the inner peripheral recording part of the disk. Thus, reading operation can be started simultaneously with the end of loading and the time until the reading start of the disk information can be shortened.
