    Abstract: Disclosed is a timing control circuit which receives a first clock having a period T1 and a group of second clocks of L different phases (where L is a positive integer) spaced apart from each other at substantially equal intervals and which generates a fine timing signal delayed from the rising edge of the first clock by a delay td of approximately td=m·T1+n·(T2/L), where m and n are non-negative integers. The timing control circuit has a coarse delay circuit and a fine delay circuit. The coarse delay circuit counts the rising edges of the first clock after an activate signal is activated and generates a coarse timing signal delayed from the first clock by approximately m·T1. The fine delay circuit has a circuit which, after the activate signal is activated, detects a second clock, which has a rising edge that immediately follows the rising edge of the first clock, from among the group of L-phase second clocks. Using the edge-detection information, the fine delay circuit generates a fine timing signal for which the amount of delay from the coarse timing signal is approximately n·(T2/L). The values of m and n can be set by registers.

    Abstract: Disclosed is a semiconductor device including a first clock generator that generates a first clock signal having a first period from an input clock signal, a second clock generator that generates a second clock signal having a second period from the input clock signal, and a timing generator that receives the first clock signal, the second clock signal, an activation signal from a command decoder and a selection signal for selecting the delay time from a timing register to produce a timing signal delayed as from activation of the activation signal by a delay equal to a sum of a time equal to a preset number m prescribed by the selection signal times the first period and a time equal to another preset number n prescribed by the selection signal times the second period. The timing register holds the values of m and n. These values are set in the timing register in an initialization sequence at the time of a mode register set command. In the operating states, the timing signals are output from the timing generator at a desired timing based on the information stored in the timing register (FIG. 6).

    Abstract: A duty detection circuit includes discharge transistors, charge transistors, detection lines, and a comparator circuit that detects a potential difference of these detection lines, and also includes a gate circuit that controls the discharge transistors and the charge transistors in response to the internal clock signal of an even cycle. As a result, the detection lines are charged and discharged in response to the internal clock signal of the even cycle. Consequently, the duty detection circuit can be applied to a multi-phase DLL circuit, and a potential difference appearing in the detection line can be sufficiently secured.

    Abstract: In one embodiment, a predetermined period different from a fixing process period in which fixing of toner to recording paper is carried out is set as a toner removal period, and during the toner removal period a hot roller and a pressure roller are intermittently rotated, and separation claws in contact with the rollers are caused to vibrate by the intermittent rotation of the rollers such that toner adhered to the separation claws is caused to drop due to this and is removed. Also, faces of the separation claws that oppose the surfaces of the hot roller and the pressure roller are set in a convex shape.
