An inkjet print head having a dummy ink chamber and a dummy heater disposed in the inkjet print head such that air bubbles gathered at edges of an ink feed hole are pushed toward an inner side of the ink feed hole when inks are sprayed. Accordingly, although air bubbles caused by the air introduced from an exterior or separated from inks are gathered at the edges of the ink feed hole, the air bubbles are forcedly pushed toward the center portion of the ink feed hole communicating with an ink storage container such that the air bubbles can flow into the ink storage container. Thus, inks are easily supplied to ink chambers adjacent to the edges of the ink feed hole, so that missing nozzles can be prevented from being generated.

Provided are a rate 13/15 MTR code encoding/decoding method and apparatus. The encoding method includes: generating a predetermined rate-13/15 MTR code in which 13-bit data corresponds to 15-bit data; outputting input 13-bit data as a 15-bit codeword according to the rate-13/15 MTR code; checking whether codewords satisfy a predetermined constraint condition by connecting the 15-bit codeword and a subsequent 15-bit codeword; and converting specific bits of the codewords if the codewords violate the constraint condition and not converting the codewords if the codewords do not violate the constraint condition. The rate-13/15 MTR (j=2, k=8) code includes: 8192 codewords obtained to prevent the number of consecutive transitions from becoming 3 at code boundaries in a modulation coding process. Data can be reliably reproduced with high write density, and a large amount of data can be stored in and reproduced from a magnetic recording information storage medium.

An ink jet image forming apparatus includes a reset correction unit to restrict a heater driving time so as to prevent a heater from being damaged due to overheating when an error occurs in a system clock. The reset correction unit may determine that an error occurs in the system clock if a discharging voltage of at least one charging circuit, which performs a charging operation using the system clock, is decreased to a reference voltage. In this case, the reset correction unit can generate a reset signal having an initial state such that the heater is no longer driven.

Disclosed herein is a polyester film for flexographic printing plates, which comprises: a polyester base layer (B); a detachable adhesive layer (A) formed on one surface of the polyester base layer using polyester resin and acrylic resin; and an antistatic layer (C) formed on the other surface of the polyester base layer. In the disclosed polyester film, the detachable adhesive layer is formed on one surface of the polyester base layer using polyester resin in combination with acrylic resin, and thus can have increased adhesion to the base layer and photosensitive resin. Also, the other surface of the polyester base layer has formed thereon the antistatic layer, which has excellent antistatic performance and, at the same time, is not transferred to a surface opposite thereto and is not greatly influenced by humidity. Thus, the disclosed polyester film is suitable for flexographic printing plates.

The present invention relates to a semiconductor photoelectric device including a InAs layer formed to monoatomic thickness sandwiched between spacer layers adjacent to an emitter to maximize a difference in energy between two quantum states in accumulation layer of a resonant tunneling diode having a double barrier structure, resulting in separating the resonant tunneling current determined by two quantum states of the triangular well in accumulation layer of resonant tunneling diode, even when light of a low intensity is irradiated to the surface of the resonant tunneling diode. Thus, there is provided an optical controlled resonant tunneling diode, making it possible to manufacturing a switching device for controlling an electric signal using light source by adjusting, using light, the resonant tunneling determined by an excited state of the triangular well.
