According to one embodiment, a mass spectrometer includes a sample stage provided to hold a sample; an analysis unit disposed to face a sample placement surface of the sample table, and performing mass analysis; an ion beam source provided to irradiate an ion beam toward the sample placement surface; an assist energy source supplying assist energy to a target area between the sample placement surface and the analysis unit; and a laser light source irradiating the target area with laser light.

Mass spectrometer and mass spectrometry method

A laser device for laser resonance ionization includes a wavelength variable grating-type titanium-doped sapphire laser and includes a titanium (Ti) doped titanium sapphire crystal disposed within a resonator. The titanium sapphire crystal is fixedly disposed on a stage. The titanium-doped sapphire crystal can be moved in the optical axis direction by the stage, thereby changing the position of the titanium-doped sapphire crystal. The switching between the wideband mode and the high-output mode can be performed by changing the position of the titanium-doped sapphire crystal.

Laser device, method for controlling laser device, and mass spectroscope

A new lignin degradation product, a method for producing the same, and methods for producing a saccharide raw material and a monosaccharide raw material are provided. The method for producing the new lignin degradation product includes: (a first step) mixing 100 parts by mass of a powder, obtained by pulverizing a lignocellulosic raw material and defatting the resulting powder with an organic solvent, with aqueous hydrogen peroxide in an amount of 20 to 400 parts by mass in terms of hydrogen peroxide and heating the mixture for 5 to 120 minutes at a pressure of 0.1 to 1.5 MPa and a temperature of 80 to 200&#xb0; C. while irradiating the mixture with microwaves; (a second step) separating insoluble matter from the aqueous hydrogen peroxide; (a third step) extracting the insoluble matter with a solvent to produce an extract; and (a fourth step) distilling the solvent away from the extract to yield a solubilized lignin as a residue. Further, a saccharide raw material composed mainly of a polysaccharide or a monosaccharide raw material is obtained by subjecting the liquid portion or the insoluble matter, respectively, obtained in the first step to a predetermined treatment.

Method and apparatus for controlling exposure of camera

A camera has a movable lens barrel that is stowed in a camera body while the camera is inactive, and is protruded from the camera body to a near range focusing position or a far range focusing position by rotating a drive ring in one direction. The movable barrel returns to the stowed position by rotating the drive ring further in the same direction, because of a cam mechanism interconnecting the drive ring with the movable barrel. To rotate the drive ring, a rotational power of a motor in a first direction is transmitted to the drive ring through a clutch mechanism. The clutch mechanism is switched over according to the rotational direction of the motor and transmits a rotational power of the motor in a second direction to another mechanism. A controller controls driving the motor in response to signals entered through manually operated members, including a power switch, a shutter button and a zone selector, with reference to detection signals from a barrel position detector.

Camera with motor-driven lens barrel

An exposure control method and apparatus for a camera having a two-area divided brightness measurement system. A central light value is determined based on a central area brightness of a photographic scene, and a peripheral light value is determined based on a peripheral area brightness of the scene. After determining by comparison between the central and peripheral light values whether the scene is back-lighted or front-lighted, a correction coefficient specific to back-lighted scenes or that specific to front-lighted scenes is read from a memory. An exposure value suitable for a main subject is calculated according to the following equation:

Spray dryer

A spray dryer which has a tank for receiving batches of differing materials to be spray dried. The tank is rotatable about a horizontal axis. The tank has an open top and a cover which is hinged on an axis perpendicular to the tank axis. The cover carries atomizer which has a shaft extending through the cover into the tank when the cover is closed. A spray disk is attached to the atomizer shaft.
