Abstract: To detect a wavelength drift of laser light with no error, an optical transmission module (10) includes: a laser diode (20); a laser temperature calculation section (52) for detecting the temperature of the laser diode (20) that monotonously increases with respect to a wavelength of the laser light; a wavelength calculation section (44) for detecting a transmittance of the laser light incident on an etalon filter (36) whose transmittance periodically varies with respect to the wavelength of the incident light, and a laser wavelength corresponding to the transmittance; and a wavelength error obtaining section (54) for detecting a wavelength error (wavelength drift), from a target wavelength, of the laser light output from the laser diode (20), based on the temperature detected by the laser temperature calculation section (52) and the laser wavelength detected by the wavelength calculation section (44).

Abstract: A technology that is applicable generally to manual noncontact card readers regardless of whether they are of insertion or swipe type, and realizes stable communication even with antennas of small size is provided. A pair of loop antennas is located in opposition to either side of a transport path, in proximity to a card insertion slot of the transport path. A magnetic circuit which connects the loop antennas together is located so as to not lie exposed in the transport path, so that, of the magnetic fluxes produced in two directions with respect to the noncontact card from the loop antennas, one of these will be diverted through the magnetic circuit without interlinking to the card.

Abstract: In a semiconductor device including a core transistor and an I/O transistor on the same semiconductor substrate, the core transistor includes a gate insulating film, a gate electrode, sidewalls, extension diffusion layers, and source/drain diffusion layers. The I/O transistor includes a gate insulating film, a gate electrode, sidewalls, and source/drain diffusion layers. In the I/O transistor, the source/drain diffusion region is offset relative to a channel region located beneath the gate insulating film in regions below the sidewalls.

Abstract: One transmission line includes a first signal conductor which is placed on one surface of a substrate formed from a dielectric or semiconductor and which is formed so as to be curved toward a first rotational direction within the surface, and a second signal conductor which is formed so as to be curved toward a second rotational direction opposite to the first rotational direction and which is placed in the surface so as to be electrically connected in series to the first signal conductor, wherein a transmission-direction reversal portion in which a signal is transmitted along a direction reversed with respect to a signal transmission direction of the transmission line as a whole is formed so as to include at least part of the first signal conductor and part of the second signal conductor. Such a transmission line is capable of obtaining a suppression effect of unwanted radiation intensity.

Abstract: A graphic accelerator includes an image-forming data decode unit, an image memory control unit and a screen data generation unit. The image memory control unit performs a control for writing an output of the image-forming data decode unit to a frame buffer and reading out information stored in the frame buffer. Screen data generation unit restores (interpolates) the color information based on the data read out from the frame buffer and generates screen data. In the frame buffer the information for each pixel is stored in a deleted form including two types of color information among three types of color information consisting of R, G and B. At the reading, the deleted color information is interpolated with the color information of other pixel.

Abstract: The antifuse is brought into an electrically conducted state by setting the voltage Vpgm to a high voltage after activating the signal SA and setting the node N1 once to an L-level. By inversion of the latch, the voltage of the node N1 will be the power source voltage Vcc to bring the transistor into a non-conducted state, whereby the electric current flowing through the antifuse is cut off. A semiconductor device can be provided which includes an antifuse program circuit capable of cutting the electric current off after blowing, so as to prevent decrease in the blowing voltage.

Abstract: A system utilizing direct-view illumination of selected regions together with principles of constructive occlusion (diffuse reflectivity in a mask and cavity structure) provides a tailored radiation intensity distribution adapted to meet the requirements of certain special applications. The direct illumination provides high intensity illumination for certain desired regions. However, some radiant energy from the system source(s) reflects and diffuses within the volume between the mask and the cavity. The mask constructively occludes the aperture of the cavity. The reflected energy emerging from between the mask and cavity provides a desired illumination, for example at a much lower intensity, for regions not covered by the direct illumination.

Abstract: An image forming apparatus has N-in-1 mode for forming an image of N documents in a sheet of paper and automatic color selection mode for deciding whether a document is a color document or a monochromatic one. When the N-in-1 mode and the automatic color selection mode are selected, color copy mode is selected if a number of color documents in N documents to be reproduced in a sheet of paper is larger than a predetermined reference value.

Abstract: An emulator probe comprising a plurality of upper connectors fixed to the upper surface of a direction changing board, the upper connectors having terminals electrically connected to the terminals of a lower connector, the upper connectors being fixed to the upper surface with different fixing angles to each other, whereby an emulator can be mounted on a user target board without deforming an emulator cable.

Abstract: A sync pattern detecting circuit detects a sync pattern from the input data to output a sync pattern detecting signal. A frame counter counts clock signals for the bit number of one frame to output a frame count signal. A sync manage circuit sets a window time area therein, and outputs a sync signal when the sync pattern detecting signal is input in the window time area. The width of the window time area is variable. The width of the window time area is controlled at timings at which the sync pattern detecting signal and the frame count signal are input.
