    摘要: A laser light source 1 is provided with an output mirror 11, a laser medium 12, a light beam diameter adjuster 13, an aperture 14, a reflection mirror 15, a drive unit 21, and a control unit 22, and outputs laser oscillation light 31 from the output mirror 11 to the outside. The laser resonator is configured so that the reflection mirror 15 and the output mirror 11 are disposed so as to be opposed to each other with the laser medium 12 placed therebetween. The reflection mirror 15 is configured such that it gives amplitude or phase variations to respective positions in the section of a light beam when the light is reflected, and the reflection mirror presents a amplitude or phase variation distribution in accordance with control from the outside, and determines the transverse mode of the laser oscillation light 31 based on the amplitude or phase variation distribution. Thus, a laser light source capable of easily controlling the transverse mode of the laser oscillation light can be realized.

    摘要: The present invention provides a semiconductor device capable of suppressing current collapse, and also of preventing dielectric breakdown voltage and gain from lowering so as to perform high-voltage operation and realize an ideal high output. On a substrate (101), there are formed a buffer layer (102) made of a first GaN-based semiconductor, a carrier traveling layer (103) made of a second GaN-based semiconductor and a carrier supplying layer (104) made of a third GaN-based semiconductor. A recess structure (108) is made by eliminating a part of a first insulation film (107) and a part of the carrier supplying layer (104). Next, a gate insulation film (109) is deposited, and then a gate electrode (110) is formed so as to fill up the recess portion (108) and cover on over an area where the first insulation film (107) remains so that its portion on the drain electrode side is longer than that on the source electrode side. Such a recess structure is employed so as to provide the high-output semiconductor device capable of performing the high-voltage operation.

    摘要: An object of this invention is to decrease the amount of ink mist while keeping the image quality high in inkjet printing. To achieve this object, printing is performed by time-divisionally driving, for each block, a plurality of nozzles for discharging ink. In preliminary discharge, the nozzles are so driven as to set the driving time interval between neighboring nozzles to the first time interval. In printing, the nozzles are so driven as to set the driving time interval between neighboring nozzles to the second time interval longer than the first time interval.
