摘要:
Provided is a method for producing a Group III nitride-based compound semiconductor having an M-plane main surface. The method employs a sapphire substrate having a main surface which is inclined by 30° with respect to R-plane about a line of intersection Lsapph-AM formed by R-plane and A-plane perpendicular thereto. R-plane surfaces of the sapphire substrate are exposed, and a silicon dioxide mask is formed on the main surface of the substrate. AlN buffer layers are formed on the exposed R-plane surfaces. A GaN layer is formed on the AlN buffer layers. At an initial stage of GaN growth, the top surface of the sapphire substrate is entirely covered with the GaN layer through lateral growth. The GaN layer is grown so that the a-axis of the layer is perpendicular to the exposed R-plane surfaces of the sapphire substrate; the c-axis of the layer is parallel to the axis direction Lsapph-AM of the sapphire substrate; and the m-axis of the layer, which is inclined by 30° from the a-axis thereof, is perpendicular to the main surface (inclined by 30° from the exposed R-plane surfaces) of the sapphire substrate.

A CMOS sensor converts optical information into an electric signal, and outputs the converted electric signal as an image signal. An imaging clock generating unit generates an imaging clock acting as a source of a drive signal that drives the CMOS sensor. A drive signal generating unit generates an imaging synchronization signal and a drive signal based on the imaging clock. A display clock generating unit generates a display clock. A display synchronization signal generating unit generates a display synchronization signal based on the display clock. A phase comparing unit compares a phase of the imaging synchronization signal with a phase of the display clock, and controls oscillation of the display clock generating unit based on a result of the comparison.

摘要:
A fluorescence observation device includes a light source supplying excitation light, an interlaced imaging device, a field memory storing an image output from the imaging device, and a difference computing unit generating a difference image. The light source supplies the excitation light such that one of the first and second field image acquiring periods in the imaging device is a fluorescence image acquiring period, and the other is a background image acquiring period. The difference computing unit switches between a first mode of subtracting a background image of the memory from a fluorescence image output from the imaging device, and a second mode of subtracting a background image output from the imaging device from a fluorescence image of the memory, to apply the mode. Accordingly, it is possible to generate images in which fluorescence is extracted in real time.

Rear wheel tires of a vehicle body are spaced apart from each other in the vehicle width direction. A foreign object removing device is provided between an outer tire and an inner tire of the rear wheels on one side of the vehicle for removing foreign objects between the tires. The foreign object removing device includes a bar-shaped member inserted in a suspended state between the tires, and a shoe provided in a lower end side of the bar-shaped member to collide with foreign objects such as earth and sand, and stones getting in between the tires for flicking out the foreign objects from between the tires. The shoe is replaceably attached to the lower end side of the bar-shaped member by using a bolt. In a case where the shoe wears down, only the shoe is replaced.
