摘要： An image forming apparatus having a process correction mode wherein when a temperature of a fixing device in an image formation system in a power-on state is equal to or less than a predetermined value, the image forming apparatus increases the fixing temperature to the predetermined value. The apparatus sets the process correction mode based on power-on information output from a first detector which detects presence of the power-on state for the fixing device and fixing temperature information output from a second detector which detects a fixing temperature in the fixing device, and sets a priority level for performing a correction processing of the color misregistration to be lower than a correction processing comprising an image density adjustment.

摘要： A signal processing device for analog-to-digital converting a burst signal has a feature of selecting a data bus to notify a disk control device of a conversion result via an NRZ data bus. The disk control device stores the result of the analog-to-digital conversion of the servo positional signal. The positional signal of a head of the disk device is digitalized in a R/W channel. Sampling for digital conversion is performed in only a window which is defined only in the vicinity of peaks of the positional signal. The values of peaks which are obtained by sampling are averaged by an averaging circuit. This enables the influence of noise occurred outside of the window to be eliminated. Although the noise in the window is sampled, its adverse influence is suppressed by the averaging processing.

摘要： A signal processing delay circuit is fabricated as a semiconductor integration circuit to cope with increase in the data transfer speed and data recording and reproducing density on a recording medium. In the delay circuit, the amount of delay of a reference delay circuit of a delay PLL is controlled to take a fixed value independent of deviation in quality of the semiconductor circuit, change in power, and alteration in temperature. A control signal supervising the delay amount of the reference delay circuit is employed to control amounts of delay of input signals supplied to a window adjustment delay circuit of a window adjustment circuit and a T/2 generation delay circuit generating a synchronizing signal. Each of these delay circuits includes an analog variable delay circuit having the same configuration. The window adjustment delay circuit is supervised by a signal obtained by weighting the control signal by a D/A converter. A data acquisition circuit and a data write circuit each include an analog variable delay circuit.

摘要： A digital subscriber line formed by terminal equipment, a network control device including a plurality of the terminal equipment, and an exchange terminal. In a waiting state of the digital subscriber line, the network control device is placed in a state which can only receive a signal. A sending portion of the network control device is driven when, at a call from the terminal equipment, the terminal control device receives a line activation signal from the exchange equipment and when, at an incoming state from the state from the exchange terminal, the terminal control device receives a line activation from the exchange equipment. The synchronization pattern signal is sent from the sending portion to the exchange terminal so that the synchronization of the exchange terminal is established.
