Provided is a DC-DC converter including a short-circuit protection circuit which can stably perform a reset operation and a stop operation. The short-circuit protection circuit includes a detection circuit, a delay circuit, and a latch circuit. The delay circuit is reset in response to an output voltage abnormality signal related to a switching regulator which is outputted from the latch circuit. The latch circuit is reset based on an AND operation between the output voltage abnormality signal and a UVLO signal.

An ESD-protection device includes a gate electrode formed on a substrate; a first diffusion region of a first conductivity type formed in the substrate at a first side of the gate electrode, a second diffusion region of the first conductivity type formed in the substrate at a second side of the gate electrode, and a third diffusion region of a second conductivity type formed in the substrate underneath the second diffusion region in contact with the second diffusion region. Thereby, the impurity concentration level of the third diffusion region is set to be larger than the impurity concentration level of the region of the substrate located at the same depth right underneath the gate electrode.

An advertising device for detachably attaching a flexible sheet-like advertising bill. The device comprises a flexible sheet member on which the advertising bill is disposed. An expansible member is disposed in an intermediate portion of the sheet member. The advertising bill is detachably fastened to the sheet member by a fastener comprising a pair of fastening elements, namely a first element and a second element. The first element is secured to the sheet member. The second element is secured to the advertising bill. The first and the second elements cooperate with each other to fasten the advertising bill to the sheet member. The peripheral edge of the sheet member is connected to an advertising place. And an adjuster is provided for adjusting a state of tension of the sheet member.

A color original is picked up by a pickup head and B, G, and R image signals are obtained and supplied to a color process circuit including masking correction, under-color removal, and gradation correction circuits. Y, M, C, and K image signals output from the color process circuit are supplied to an exposure head to form a color separation plate. A print simulation unit having first and second frame memories is connected in parallel with the color process circuit. The B, G, and R signals are also written into the first frame memory. The signal read out from the first frame memory is supplied to the color process circuit and is color-corrected. The output from the color process circuit is written into the second frame memory and output to a color monitor. The second frame memory stores two frames, and can display both frames on the color monitor for comparison. The second frame memory has a data latch for latching a predetermined pixel signal, and a circuit for synthesizing the latched data in place of a predetermined pixel signal of the image signals. The second frame memory further has a comparator for detecting a pixel of the image signals having a level higher than a highlight set level, and a circuit for flashing the pixel having a level higher than the highlight set level.
