摘要:
An ozone filtering mechanism in an image forming apparatus such as office copiers, etc. and its arrangement, wherein various component elements disposed in the image forming apparatus in such a manner that a flow path for a discharge current of ozone gas generated from a corona discharger and a flow path for heat current from a heat source such as a light source, etc. may be centralized at one place, thereby enabling a single ozone filter to be disposed at this portion of the centralized flow paths for perfect ozone filtration. Presence of the heat current at the time of the ozone filtration promotes adsorption and decomposition of ozone to augment the filtering effect to the maximum possible extent.

The object of the present invention is to provide a biomarker which is highly correlated to the conventional biomarkers of metabolic syndrome or life-style related disease in a wide range of subjects to be tested, including subjects of special health check-up aged between 40 and 74, or an advantageous method for detecting metabolic syndrome or life-style related disease. The object can be solved by a method for detecting metabolic syndrome or life-style related disease by measuring the concentration of choline plasmalogen in a sample to be tested.

摘要:
An amplifier for receiving an optical signal is disclosed. The amplifier provides a response time controller including an integrator with two time constants, a linear amplifier, a hysteresis comparator, an another integrator, and a switch to change the time constant. The switch includes two voltage followers, one of which turns off the switch to set the time constant in a longer state; while, the other of which turns on the switch and reflects the input of the integrator to set the time constant in a shorter state.

A fundus camera includes an illumination optical system, an observation photographic optical system, a photographic diaphragm unit located in a position conjugate with the subject's eye in the observation photographic optical system, and an imaging unit disposed in the observation photographic optical system. The photographic diaphragm unit includes a first photographic diaphragm fixed during capturing of a still image and a second photographic diaphragm movable during capturing of a moving image. The fundus camera further includes a diaphragm driving unit configured to move the second photographic diaphragm on a plane orthogonal to an optical axis, an image recording unit configured to capture, with the first photographic diaphragm, a still image based on an output of the imaging unit and, with the second photographic diaphragm, a moving image based on an output of the imaging unit, and a display unit configured to display an image captured by the imaging unit.

An object of the present invention is to provide a pitch carbon fiber having a decreased occurrence of cracking along the direction of the fiber axis of the pitch carbon fiber, which has conventionally occurred in a melt blowing method, and having high thermal conductivity.The invention is directed to a pitch carbon fiber having a melt mark recognized in the fiber corresponding to 60 to less than 100% of the cross-section of the fiber, and having a lattice spacing (d 002 value) of 0.3362 nm or less in the graphite layer and a crystallite size (Lc) of 60 nm or more derived from the thicknesswise direction, as determined by X-ray diffractometry. The pitch carbon fiber can be produced under specific conditions for spinning and infusibilization.
