Abstract: There are provided a voltage level control circuit with a reduced power consumption and a method of controlling the same. When a signal “A” is in a “L” level and a signal PL entered from the outside of the voltage level control circuit becomes .“H” level, a latch signal La outputted from a latch (11) becomes “H” level, whereby NFETs (14, 17, 24) turn ON. A voltage dividing circuit comprising resistances (12, 13) and current mirror differential amplifiers (20, 27) are placed in active states to output “H” as a signal A which controls a boost voltage Vbt (word line driving voltage. As the boost voltage Vbt is increased and reaches to a reference voltage Vref2, a voltage V2 becomes “H”, whereby the signal A becomes “L”. After the signal A become “L”, the latch (11) is made through. At this time, the signal PL is “L”, the latch signal La outputted from the latch (11) becomes “L”, whereby the NFETs (14, 7, 24) turn OFF.

Abstract: A pattern analyzing portion analyzes a pattern of a detected repeat field and determines whether or not the pattern of the repeat field is continuous. An inverse pull-down controlling portion controls a memory to read video data in such a manner that the repeat field detected by a comparator is removed from input video data in a period that the pattern of the repeat field is continuous. The inverse pull-down controlling portion controls the memory to read video data in such a manner that a repeat field detected by the comparator is not removed from the input video data in a period that the pattern of the repeat field is discontinuous. In other words, an inverse 2:3 pull-down process is controlled corresponding to the continuity of a pattern of a repeat field. In addition, it is determined whether an input original material is a progressive-scanned video material or an interlace-scanned video material corresponding to the continuity of the pattern of the repetitive material.

The antenna includes two transmission lines provided along the conveyance path, and generates a magnetic field between the transmission lines perpendicularly with respect to the surface of the radio communication medium conveyed. Accordingly, when the radio communication medium is conveyed between the two transmission lines, it passes through a uniform magnetic field generated over a relatively long distance, over which the transmission lines run. As a result, stable communication can be established over the relatively long distance.

Abstract: An image forming apparatus which eliminates the necessity of carrying out wasteful operations such as retry of a job and therefore improves work efficiency. A print job is carried out to thereby form an image on a recording sheet. When an image abnormality formed on the recording sheet is detected, a controller temporarily suspends the print job. An operating unit displays a screen for prompting a user to input an instruction as to whether to continue the print job. The controller determines whether to continue the print job based on the instruction input by the user.
