A capsule optical sensor includes an illuminator and a sensor. The illuminator has a light source that produces light in the wavelength range from 600 to 2000 nm and the sensor has a photoelectric detection element and a variable spectroscopic element in front of a light receiving surface of the photoelectric detection element that can separately detect emissions from different fluorescent labels. Alternatively, the sensor may have plural photoelectric detection elements and optical filters in front of light receiving surfaces of plural photoelectric detection elements, with the optical filters transmitting different wavelength bands so as to separately detect the emissions from different fluorescent labels. Also, the sensor may be a photoelectric detection element having a stack of light receiving layers, each for detecting a different fluorescent emission. In all cases, the sensor does not provide an imaging function, thereby minimizing the size of the capsule optical sensor.
摘要:
An endoscope system is disclosed for detecting fluorescent light emitted in the near-infrared region by a plurality of fluorescent labeling materials introduced into a living tissue. An illumination system generates illumination light in the wavelength range 600 nm-2000 nm which serves as excitation light for the plurality of fluorescent labeling materials, and a detection system that can separately detect different ones of the plurality of fluorescent light emissions that are emitted at different wavelengths from among the plurality of fluorescent labeling materials is provided. The endoscope system may include a conventional-type endoscope having an insertion section, or a capsule endoscope that wirelessly transmits image data. By superimposing the image data obtained using reflected light in the visible region and fluorescent light emitted by the fluorescent labeling materials, improved diagnostic capabilities are provided.
摘要:
A light source device for endoscopes capable of preventing an incident end-face of a lightguide from generating heat due to infrared light emitted from a light source, and capable of radiating sufficient ultraviolet light and visible light. A light source emits at least ultraviolet light, visible light and infrared light. A condenser lens condenses the light emitted from the light source at the incident end-face of a light guide. A wavelength control filter and another selected filter are arranged between the light source and the condenser lens. Each optical axis of the light source, the wavelength control filter, the selected filter, the condenser lens, and the lightguide is linearly aligned, thereby providing a simplified alignment operation in manufacturing processes.

A light source device for endoscopes includes a light source for emitting white light containing the components of light belonging to a visible region and wavelength bands other than the visible region; at least, a rotary color separating filter on a field sequential system; and an infrared cutoff filter for blocking light in an infrared region, of a wavelength band of the white light. When the rotary color separating filter is disposed in an optical path from the light source to a light guide, an interference filter in which an interference film is applied to a transparent base plate is placed in the optical path. This arrangement obviates the defect of burning the entrance end of the light guide or of breaking the infrared cutoff filter.

An optical low pass filter consisting of a diffractive optical element consisting of a plurality of regions which have different imaging characteristics and are joined adjacent to one another so that the imaging characteristics are varied discontinuously. This optical low pass filter is to be used for optical instruments using solid-state image pickup devices and so on.

When a management screen for conducting management operation of a file system in the NAS apparatus 10 of a file server is displayed by the administrator on a display device of the management console 30 by using the management console 30, if a disk device obtained from the storage apparatus 20 is in a power saving state, the NAS apparatus 10 has a function to change the operations hereafter. Specifically, a screen is displayed on the management screen, in which a creation or deletion of the file system becomes impossible with respect to the disk device in the power saving state. Therefore, the administrator can conduct management operations for services without referring to the power status, thereby resulting in easy management operation.
摘要:
A multi-stage transmission has driving gears m and driven gears n in constant mesh and supported for being individually engageable and disengageable with a hollow driven gear shaft. The transmission realizes a smooth speed change by providing cam rods within the driven gear shaft for engagement and disengagement between the driven gears n and the driven gear shaft and by providing compact lost motion mechanisms with axially acting springs for the cam rods, respectively. Swing pawl members each disengageably engage projections formed at circumferentially spaced positions on the inner peripheral surface of each driven gear n to control engagement and disengagement between each driven gear n and the driven gear shaft. The cam rods are moved in the driven gear shaft to operate the swing pawl members. Gear shift driving means includes a control rod moved in sliding contact with the inner surfaces of the cam rods.

A multi-stage transmission has driving gears m and driven gears n that mesh constantly and are supported on a hollow driven gear shaft. The driven gears n are individually engageable with and disengageable from the hollow driven gear shaft. Swing pawl members control engagement and disengagement between each of the driven gears n and the driven gear shaft, and cam rods inserted in the driven gear shaft to slide relative to the internal surface of the shaft to operate the swing pawl members. Gear shift driving member includes a shift drum, a control rod in sliding contact with the inner surface of the cam rods to axially move the cam rods, and a control rod operating element responsive to rotation of the shift drum to move the control rod. The control rod and the driven gear shaft are prevented from relative rotation by an anti-rotation mechanism.
摘要:
Driven gears are supported on a hollow driven gear shaft in a manner engageable with and disengageable from a hollow driven gear shaft via swing pawl members. The transmission has first a engaging member for engaging the gear shaft with a first driven gear, so as to effect synchronous rotation thereof and a second engaging member for engaging the gear shaft with a second gear, one step lower in the reduction gear ratio than the first gear, so as to effect synchronous rotation thereof. When making an upshift by changing over the engaging member from the engagement with the first gear to the engagement with the second gear, the gear shift is made by engaging the second gear with the gear shaft through the second engaging member while the first gear is being in engagement with the gear shaft through the first engaging member.
