Abstract: PURPOSE:To decrease cost and to obtain satisfactory image quality by composing an exposure means of a scanning exposure device, and providing a part of an exposure path with an optical diverging/converging means. CONSTITUTION:The image face of an original 2 placed on a contact glass 1 is irradiated with light from an exposure lamp 3.

Abstract: PURPOSE:To improve the acceleration properties and power characteristics at the time of highland transit with no increased NOx by guiding negative pressure into the negative pressure supply passage when the atmospheric pressure has become lower than a fixed value. CONSTITUTION:In the highland transit state the atmospheric pressure lowers so that the bellows 43 extends, a piston 41 travels toward left, a connecting hole 44 connects the connecting ports 46, 47, negative pressure is guided into the secnod negative pressure chamber 30, the insides of the first and second negative chambers 20, 30 become equal-pressured and no force acts on the first diaphragm 19. However, as the set load of the first spring 25 is set up bigger than that of the second spring, the second spring 33 is compressed to lead angle. When the negative pressure is further increased, the angle leads resisting the force of the first spring 25 to compensate the engine power lowering caused by the lowered atmospheric pressure.

Abstract: PROBLEM TO BE SOLVED: To vary the wavelength of laser light continuously at high speed only through electrical control by controlling the drive voltage from a voltage supply means based on a phase difference provided from a phase shift means and modulating the laser light through an acoustooptic means. SOLUTION: Laser light emitted from a laser diode 2 enters into a mirror 7 through first and second acoustooptic tunable filters AOTF3, PBS4 and AOTF5, PBS6 thence enters again into the laser diode 2. When a phase difference is imparted to a drive voltage from a power supply section for the AOTFs 3, 5, phase of a light passing through the AOTFs 3, 5 is varied. Since the wavelength of light can be varied electrically, variation of the modulation frequency and the phase difference can be interlocked constantly and the wavelength can be varied continuously with high response over a wide range.
