摘要： 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).

摘要： 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.

摘要： A duty correction circuit is formed using at least one delay circuit, which is constituted of a first inverter including three transistors of different conduction types and a second inverter including three other transistors of different conduction types and which delays and adjusts an input clock signal at the leading-edge/trailing-edge timing so as to convert it into an output clock signal based on a first or second bias voltage produced by a bias circuit detecting the duty ratio of the output clock signal. The duty correction circuit decreases the high-level period of the output clock signal having a high duty ratio based on the first bias voltage. Alternatively, the duty correction circuit increases the high-level period of the output clock signal having a low duty ratio based on the second bias voltage.

摘要： In an image forming apparatus of the present invention, an idle roller once stops rotating when a front edge of a sheet conveyed reaches the idle roller. The idle roller restarts rotating at such a timing that a front edge of a toner image on a photoreceptor and a front edge of an image writing position on the sheet are aligned with each other. Then, even if a rear edge of the sheet is still in the idle roller, the idle roller stops rotating when the front edge of the sheet is sandwiched between a transfer roller and the photoreceptor. By carrying out such operations, it is possible to avoid by a very simple way an occurrence of a slip phenomenon that is a phenomenon of slipping of the sheet with respect to the photoreceptor while suppressing a reduction in image quality as much as possible. In addition, it is also possible to surely secure a blank space formed at a rear edge portion of the sheet.
