摘要:
An optical connector is selectively attachable to one of optical fiber cables including a first type optical fiber cable and a second type optical fiber cable. Each of the optical fiber cables includes a common optical fiber and a common ferrule fixed to the common optical fiber. The first type optical fiber cable further includes a tension member. The second type optical fiber cable further including a tensile member. The optical connector has a swage portion through which the common ferrule is inserted forward when one of the optical fiber cables is attached to the optical connector. The swage portion has an outer surface on which the tensile member is swaged when the second type optical fiber cable is attached to the optical connector. The optical connector also has a fixing portion having at least one receiver hole formed therein for receiving and fixing an end of the tension member of the first type optical fiber cable. The fixing portion is located forward of the swage portion.

An electronic endoscope system, which is adapted to observe a fluorescence image of autofluorescence emitted from a body cavity wall irradiated with excitation light, includes a controller that controls a light source apparatus to alternately introduce either white light or excitation light into a light guide while taking a normal color image and the fluorescence image, and controls an image signal generating system to generate normal color image signals and fluorescence image signals. The controller further controls a display device to display a still fluorescence image in a first window defined on a displaying area thereof based on the fluorescence image signals which have been generated when a still image switch is turned ON during the time to take the fluorescence image, and simultaneously to display a moving normal color image in a second window defined on a displaying area thereof based on the normal color image signals generated every time the body cavity wall is intermittently illuminated with the white light, the first window being larger than the second window.

A scanning endoscope, comprising a first transmitter, an actuator, and a mirror, is provided. The first transmitter emits a beam of radiant light from the first emission end. The actuator moves the first emission end in a direction perpendicular to an emission direction. The mirror is arranged from the first emission end to the first direction. The mirror comprises a through-part and a reflection surface. The radiant light emitted from the first emission end passes through the through-part when the first emission end is within a first circumference. The reflection surface reflects the radiant light emitted from the first emission end toward the observation area around the first straight line when the first emission end is outside of the first circumference.

An endoscope system comprises a light source, a light sensor, a signal processor, a video-signal generator, and a switcher. The light source emits red light including a first wavelength, green light including a second wavelength, and blue light including a third wavelength. The light sensor receives the light of the light source. The signal processor obtains a red signal based on the red light, a green signal based on the green light, and a blue signal based on the blue light. The video-signal generator generates video signal based on the red, green, and blue signals. The switcher switches between a first switching state and a second switching state. The red, green, and blue signals are output to the video-signal generator in the first switching state. The green and blue signals are output to the video-signal generator in the second switching state.

An endoscope shape monitoring system that is used to grasp a shape of a flexible insertion portion is provided that includes a position detector and a determining processor. The position detector detects a plurality of positions of the insertion portion along the central axis of the insertion portion at predetermined intervals. The determining processor determines the position of at least one of the central axis or an outline of the insertion portion.
摘要:
A pilot injection amount QP, a main injection amount QM, and a lag TDF between the main and pilot injections are obtained (S130). The pilot injection initiating timing TTP, the pilot injection period TP, the main injection initiating timing TTM, and the main injection period TM are obtained on the basis of the pilot injection amount QP, the main injection amount QM, the fundamental injection initiating timing KT and the common rail pressure Pc (S150). The main injection period correction amount .DELTA.TQM and the injection initiating timing correction shift amount .DELTA.T are then obtained on the basis of the pilot injection period TP and the time lag TDF (S160). Finally, modified by these correction amount .DELTA.TQM and the shift amount .DELTA.T, the pilot injection initiating timing TTP', the main injection initiating timing TTM' and the main injection period TM' are obtained as final values (S170). With this arrangement, a fuel injection control apparatus for an internal combustion engine becomes capable of reducing adverse affects of residual magnetic flux and the pressure pulsation in the fuel injection initiating timing of the main injection, thereby suppressing smoke generation and realizing an optimum fuel injection.
