摘要： An image processor includes an encoder that performs encoding including quantization on an image signal and a controller that controls a quantization parameter for quantization. The controller determines a quantization parameter of a currently target macroblock as an increase or decrease from a reference value, and determines the increase or decrease based on a difference between a target amount of code for a predetermined number of macroblocks fewer than a total number of macroblocks within one frame and a generated amount of code of the predetermined number of macroblocks processed immediately before. The controller can further determine the increase or decrease, based on pixel information of the currently target macroblock such as an activity evaluation value.

摘要： A beam irradiation apparatus includes a light source which outputs a laser beam, a convergent lens into which the laser beam output from the light source is entered, and a scanning portion which makes the laser beam transmitted through the convergent lens scan on a target region. In the beam irradiation apparatus, the laser light source is arranged such that a pn junction surface of a laser chip is parallel with the vertical direction. Length of the laser beam in the vertical direction on the target region is set by length of a light emitting portion of the laser light source in the vertical direction. Further, a wavefront aberration of the convergent lens with respect to the laser beam is set to be 0.15 λrms or less.

摘要： An object of the present invention is to provide a detection device which does not cause the false detection by receiving laser light from an oncoming car. The pulse laser light modulated with a modulation pattern set every target position is irradiated at the target position from a laser irradiation portion. DSP (Digital Signal Processor) decides that there is an obstacle at the target position only when the modulation pattern of the pulse laser light emitted from the laser emitting portion matches with the modulation pattern of the pulse laser light received by the laser receiving portion. It is suppressed that the detection device misdetects the conditions of the target position when receiving laser light from an oncoming car or the like because modulation pattern of laser light from own does not match with modulation pattern of laser light from the oncoming car or the like.

摘要： By providing a nitrogen-doped low carrier concentration layer 13 having both of a donor concentration and an acceptor concentration controlled below 1×1016/cm3 at a p-n junction portion between an n-type GaP layer 12 and a p-type GaP layer 14, the luminance of the GaP light emitting device can be improved by as much as 20 to 30% over the conventional one. Suppressing the donor concentration and the acceptor concentration in the low carrier concentration layer 13 below 1×1016/cm3 inevitably gives a carrier concentration, which is expressed as a difference between both concentrations, lower than 1×1016/cm3 accordingly. The emission efficiency upon injection of electrons or holes can be improved by suppressing the concentration of the donor which serves as non-emissive center below 1×1016/cm3 to thereby extend the carrier lifetime; and by concomitantly suppressing the carrier concentration at a level significantly lower than that in the adjacent layers 12 and 14.

摘要翻译： 通过在n型GaP层12和p型GaP层14之间的pn结部分提供具有供体浓度和受主浓度两者的氮掺杂低载流子浓度层13，其控制在1×1016 / cm3以下， 的GaP发光器件可以比传统的发光器件提高多达20至30％。 抑制低载体浓度层13中的供体浓度和受体浓度低于1×10 16 / cm 3时，不可避免地会产生一个载流子浓度，其表示为两个浓度之间的差值，相应地低于1×10 16 / cm 3。 通过抑制作为不发光中心的供体的浓度低于1×10 16 / cm 3，可以提高注入电子或空穴的发射效率，从而延长载体寿命; 并且通过伴随地将载流子浓度抑制在显着低于相邻层12和14中的水平。

摘要： An efficient method is proposed for the determination of the concentration of nitrogen in an indirect-transition compound semiconductor such as gallium phosphide added as an isoelectronic trap. The method utilizes the fact that a good correlation of proportionality is held between the nitrogen concentration and the difference .DELTA..alpha.(=.alpha..sub.N -.alpha.) in the absorption coefficient of light of a wavelength identical with the wavelength .lambda..sub.N due to the excitons under constraint in the isoelectronic trap between the semiconductors with (.alpha..sub.N) and without (.alpha.) addition of nitrogen. A working curve is presented between the nitrogen concentration determined by the method of SIMS and the value of .DELTA..alpha..

摘要： To manufacture epitaxial wafers with a smaller amount of semiconductor crystals at a lower cost by means of an efficient epitaxial growth process. An epitaxial wafer is made by forming, by means of epitaxial growth, GaAlAs layers with identical structures on both sides of a GaAs substrate wafer with the crystal plane orientation of {100}. The epitaxial wafer is then divided in the GaAs substrate wafer portion into two pieces to obtain two epitaxial wafers. To perform the epitaxial growth process, a plurality of GaAs substrate wafers are held at their edges and then the GaAs substrate wafers are placed in a Ga solution at prescribed spatial intervals. To divide the epitaxial wafer in the GaAs substrate portion into two pieces, the substrate wafer portion is cut parallel to the main surface. Or, the GaAs substrate wafer can also be removed by means of etching while the epitaxial wafer is rotated at a high speed in the etching solution.

摘要： A multiple wavelength light emitting device having a single p-n junction and at least two light emitting layers within a diffusion region of a minority carrier comprises a p-type Ga.sub.1-x1 Al.sub.x1 As layer, a p-type Ga.sub.1-x2 Al.sub.x2 As layer, a p-type Ga.sub.1-x3 Al.sub.x3 As layer, and an n-type Ga.sub.1-y Al.sub.y As layer, where x.sub.1, x.sub.2, x.sub.3 and Y represent aluminum arsenide mixed crystal ratios of the respective layers. The light emitting alyers, i.e., the p-type Ga.sub.1-x2 Al.sub.x2 As layer and the p-type Ga.sub.1-x3 Al.sub.x3 As layer each have a different band gap to emit an infrared light and a visible light, respectively. Since the infrared and ivsible lights are simultaneously emitted, emission of the infrared light can be confirmed or monitored by the visible light. The light emitting device of the present invention utilizes an energy well for trapping electrons and an energy barrier for preventing electrons from diffusing to improve the whole light emitting efficiency.
