Title: Circuit and method for acquiring and verifying data
Inventor: JIEFURII ERU SHIYUWARUTSU
IPC: G06F13/42
Filed: 1992-08-21
Abstract: PURPOSE: To acquire asynchronous data and to convert the data to synchronous data usable in timing type logic design by using interface state machine and data verification decoding logic. CONSTITUTION: This circuit is achieved by the three stages of micro-channel interface state machine and logic mechanisms 170, 172 and 174.

Title: Servo device in recording disk reproducing device
Inventor: NAKAMURA HIROSHI
IPC: G11B7/09
Filed: 1986-09-20
Abstract: PURPOSE:To contrive the simplification of a circuit constitution and to reduce a cost by setting the sampling period of a tracking error signal to be smaller than the sampling period of a focusing error signal so as to enable a signal processing circuit to be used in common. CONSTITUTION:The sampling period of the focusing error signal is doubled in comparison with that of the tracking error signal. This is because the mass of an actuator being a controlled system is larger than that of a tracking servo system, resulting in giving a bad response in the focusing servo system and sufficient control is attained even with a largely set sampling period. In other words, since the sampling period of the tracking error signal is decreased in turn by increasing the sampling period of the focusing error signal, the tracking accuracy is improved by the decrease. The increase in the sampling period is not limited to 'twice', but a value being twice or over is preferred.

Filed: 1984-10-25
Abstract: PURPOSE:To detect promptly breaking impossibility of a current switching element and to prevent previously serious accident by making comparison with time lag of current flowing to pair of current limiting resistance generated while switching one tap. CONSTITUTION:At the time of normal changing, a current switching element HA is opened and a non power supply light output voltage detection section 5 is emitted just as quenching arc and is maintained during t1+t2 until an element WA cuts off electric current.

As the formula is t1<T1, t2>T2 respectively at the time of breaking impossibility, t1 and t2 are transmitted to an abnormal measuring section 6 promptly observing t1 and t2 respectively, then a line breaker of a tap changing transformer 1 is subjected to trip red heat of a current emitting resistance 4, thus serious accident is prevented. The variation of electric current I of the current limiting resistance 4 is picked up with voltage, then full-wave recification is performed and impresses to LED through a Zenar element DZ and detected light is introduced to the measuring section 6 through an optical fiber 8, thus conduction time lag is compared.
