A close-up imaging device that generates slit light on the basis of light-source light emitted from a light source built into a mobile communication terminal device. The close-up imaging device is mounted onto the mobile communication terminal device, and a moving image of the tissue to be observed of the examined eye is captured by a camera module built into the mobile communication terminal device. Then, in a diagnosis support server device, a diagnosable frame image included in the captured moving image is extracted, at least one of a heath state of the examined eye and any one or more of a distance, an angle, and an area in some tissue of the examined eye is estimated on the basis of the diagnosable frame image extracted, and diagnosis support information is generated and distributed to the corresponding mobile communication terminal device.

Diagnosis support device, diagnosis support system, and program

To provide a close-up imaging device whereby both imaging of an anterior eye and imaging of an eye ground can easily be performed by attaching the device to a mobile terminal such as a smartphone. The above-described problem is solved by a close-up imaging device (B) detachably mounted to a mobile terminal () equipped with a light source () and a camera lens () for imaging, comprising a color filter member () detachably provided above the light source (), and a convex lens member () detachably provided above the camera lens (). Imaging, of an anterior eye is performed by removing the color filter member () and attaching the convex lens member (), and observation of an injury of the anterior eye is performed by attaching the color filter member () and the convex lens member (). The close-up imaging device (B) may further detachably comprise a slit light forming member that forms light from the light source () into slit light by a cylindrical lens, and a tubular member including a convex lens at a tip end thereof.

According to one implementation, a rotorcraft includes rotors, a fuselage, at least three rods, at least one load sensor and a control device. The rotors obtain lift. The fuselage is coupled to the rotors. The at least three rods support the fuselage. The at least one load sensor detects loads applied on the at least three rods. The control device automatically controls the rotors so that measured values of the loads detected by the at least one load sensor are brought to targeted values of the loads.

An elastic blade includes a contact edge to contact a contact object, an edge region including the contact edge and having a thickness smaller than or equal to 0.50 mm, and a backup region different in material or property from the edge region. The backup region is adjacent to the edge region on a cross section perpendicular to a direction in which the contact edge extends. The elastic blade has a converted Martens hardness X (N/mm) in a range of from 0.9 to 2.9. The converted Martens hardness is defined as:

An image forming apparatus, includes an image carrier; a power supply; a charging member, to which the power supply applies a direct current (DC) charging voltage, to charge a surface of the image carrier; and a controller. The controller causes the power supply to apply, to the charging member, the DC charging voltage of a sum of a reference voltage VC and a correction amount &#x3b1;, so that a charged potential VD of the surface of the image carrier assumes a target value that is substantially equal to the reference voltage VC; and to increase an absolute value of the correction amount &#x3b1; to be added to the reference voltage VC in inverse proportion to an absolute value of the reference voltage VC, when the absolute value of the reference voltage VC is smaller compared to a case in which the absolute value of the reference voltage VC is greater.
