Abstract: The present disclosure relates to a comparator, an AD converter, a solid-state imaging device, an electronic apparatus, and a comparator control method that can reduce power consumption while increasing the determination speed of the comparator. The comparator includes a comparison unit, a positive feedback circuit, and a current limiting unit. The comparison unit compares the voltage of an input signal and the voltage of a reference signal, and outputs a comparison result signal. The positive feedback circuit increases the transition speed at the time when the comparison result signal is inverted. The current limiting unit limits the current flowing in the comparison unit after the inversion of the comparison result signal. The present disclosure can be applied to comparators, for example.

Abstract: A mobile electronic apparatus comprises a display including a display area having a first edge and a second edge, an input unit including a detector, and at least one processor. The display displays a display screen on the display area. The detector detects an operation performed on the display area. The at least one processor places a mode change element adjacent to the first edge or the second edge of the display area, scales down the display screen in response to detection of a first operation performed on the mode change element, and displays the display screen, which is scaled down, as a scaled-down screen on a part of the display area. The at least one processor determines, in response to a user's input to the input unit, which one of the first edge and the second edge is to be adjacent to the mode change element.

Abstract: A mobile terminal device includes: a display surface; a display control module that displays on the display surface a first input screen with a plurality of character keys which input characters and a second input screen having larger intervals between at least some of adjacent character keys than intervals between all of adjacent character keys of the first input screen, in a switchable manner between the two input screens; and a delete key for deleting a character input by the character key. In this arrangement, the display control module executes control for changing the first input screen to the second input screen based on fulfillment of a condition for changing including deletion of a character by the delete key when the first input screen is displayed on the display surface.

Abstract: A mobile phone 10 comprises a display 14, a touch panel 16, etc. A sentence is displayed on the display 14 by means of a sentence producing function, for example. If a user performs a selection operation to the sentence in this state, it is rendered in a state where a character string that is arbitrarily selected is sandwiched by a first cursor and a second cursor. If a slide operation in a rightward direction is performed when a character string being in a selected state is a single character, the first cursor is fixed and the second cursor is moved in the rightward direction. On the other hand, if a slide operation in a leftward direction is performed, the second cursor is fixed and the first cursor is moved in the leftward direction.

Abstract: A color imaging element, a photosensor and a photoelectric transducer which use a protein and are capable of being stably used for a long time, and methods of manufacturing them are provided. A zinc-substituted cytochrome c552 is immobilized on a gold electrode with a self-assembled monolayer in between to form a blue-light photoelectric transducer. Alternatively, a cytochrome c552 is immobilized on a gold electrode with a self-assembled monolayer in between, and a fluorescent protein absorbing blue light is bonded to the cytochrome c552, thereby forming a blue-light photoelectric transducer. These photoelectric transducers each are used as a color imaging element or a blue-light photoelectric transducer of a photosensor.

Abstract: There are provided a manufacturing method and a manufacturing apparatus for Baumkuchen for easily and properly suppressing shape distortion of the Baumkuchen caused in a manufacturing process thereof. In manufacturing the Baumkuchen by alternately repeating application of batter around the whole outer circumference of a spit and baking of the applied batter, the batter is scraped off outer circumferences of opposite end portions of the spit before baking only in early stage of manufacturing until the number of repetitions reaches a specified value. As a result, the number of cake layers formed at the opposite end portions of the Baumkuchen is reduced from that at the other portion and outside diameters of the opposite end portions are reduced from a normal outside diameter to thereby suppress partial increase in the outside diameter at the opposite end portions of the Baumkuchen caused by drooping of the batter at the end portions of the spit before baking.
