摘要: A spectrum measuring device including a ribbon element, a light detection element, and circuitry. The ribbon element includes a first light reflector including a plurality of first light reflection surfaces configured to be translated in an out-of-plane direction, and a second light reflector including a plurality of second light reflection surfaces that are fixed. The circuitry supplies a drive signal to the ribbon element in such a manner that a change of a displacement amount difference between the first light reflection surfaces and the second light reflection surfaces corresponds to a predetermined frequency; and acquires the light quantity data detected by the light detection element at a predetermined sampling frequency.

摘要: A movable diffraction element and a spectroscope. The movable diffraction element includes a movable component having a comb-like shape, a supporting unit configured to support the movable component, a first cantilever actuator coupled to the supporting unit, a displacement determiner coupled to an edge of the first cantilever actuator, and a second cantilever actuator disposed parallel to the first cantilever actuator. In the movable diffraction element, a slope generated when the second cantilever actuator deforms is approximately equivalent to a slope generated at the first cantilever actuator. The spectroscope includes the movable diffraction element.

摘要: A spectral measurement device includes a light reflection grating having a plurality of movable gratings and a movable grating drive unit that displaces the movable gratings to alter a grating pattern of the light reflection grating, a light detecting element that detects light incident on the light reflection grating, a storage unit storing a relationship between a light quantity to be detected by the light detecting element and corresponding light intensities at differing wavelengths for different grating patterns, and a computation unit that calculates light intensities at the differing wavelengths of the light incident on the light reflection grating based on the light quantity of the incident light detected by the light detecting element for each of the different grating patterns by altering the grating pattern based on the relationship between the light quantity and the corresponding light intensities for the different grating patterns stored in the storage unit.

摘要: Disclosed is a temperature sensor using a work-function-difference-based radiant-ray detecting element that outputs, as a detecting signal of radiant rays, a work function difference between gate electrodes of first and second field-effect transistors sensing the radiant rays.

摘要: In an image forming apparatus, a distance adjusting unit adjusts an inter-unit distance between a contact unit and an image carrier by moving the image carrier or the contact unit by applying an opposing force to the image carrier or the contact unit against a biasing force applied by a biasing unit based on thickness information of a recording sheet acquired by a thickness-information acquiring unit and data indicating a relationship between the thickness information and an inter-unit distance change amount stored in a data storage unit.

摘要: A fluctuation detecting unit detects a fluctuation of an endless belt generated when a sheet is brought into contact with a predetermined position of the endless belt at an upstream side in a conveying direction from a nip portion based on fluctuation information acquired by a fluctuation information acquiring unit. An entry timing estimating unit estimates entry timing of the sheet into the nip portion based on a detection of the fluctuation. A correction control unit corrects a speed fluctuation of the endless belt generated when the sheet enters the nip portion by performing a feedforward control of a first driving unit based on the entry timing.
