摘要:
A lens-driver for driving a lens for compensating image blur caused by camera shaking has two driving-levers. In each driving-lever, one end is rotatably connected to a lens frame via a holding shaft and the other end is rotatably supported by a rotation shaft. Two driving levers are arranged generally on one straight line, and there is formed a generally perpendicular angle by a line connecting the holding shaft of one driving-lever and an optical center of the lens, and a line connecting the holding shaft of the other driving-lever and the optical center. Another lens-driver has two driving mechanisms. One driving mechanism drives the lens, and the other driving mechanism drives a shutter mechanism or an aperture mechanism. In the lens barrel, one mechanism occupies one half area and the other mechanism occupies the other half area.

The fuel cell device is provided with: an electricity-generating unit having a fuel electrode (102), an air electrode (103), and an electrolyte film (101) sandwiched between the fuel electrode (102) and the air electrode (103); a hydrogen-generating member (104) that, by means of an oxidation reaction with water, generates hydrogen for supplying to the fuel electrode (102) of the aforementioned electricity-generating unit; a heater (105) that heats the hydrogen-generating member (104); a temperature sensor (106) that detects the temperature of the hydrogen-generating member (104); and a temperature control unit (20) that controls the temperature of the hydrogen-generating member (104) in response to the detection results of the temperature sensor (106). The temperature control unit (20) stops the passage of electricity through the heater (105) when it has been determined that the temperature of the hydrogen-generating member (104) is at least a predetermined temperature.

A compensator for correcting a possible blur of image caused by a shake of an image pickup apparatus in which the compensator is arranged, and in which a downsize circuit board having a diminished area thereof and holding an image taking component is swung or moved. The compensator includes the circuit board with the diminished area for holding the image taking component, in which the circuit board is moved together with the image taking component. On the circuit board, there are arranged the image taking component and at least one other component. The at least one other component can be a component which is associated with reading of the signal(s) of the image outputted from the image taking element, and/or can be a component which is associated with the control to correct the possible blur of the image caused by the shake of the image pickup apparatus.

A container apparatus for an object to be dropped, which contains an object to be dropped functioning as a point marker or a hydrographic conditions measuring device or the like and is dropped by a transport airplane such as an aircraft flying in the air to a water surface of sea, lake or the like, or to land or the like. The container apparatus follows a substantially uniform trajectory after being dropped by the transport airplane, and after being dropped, reduces the flight speed thereof to a fixed speed, to release the object to be dropped housed therein.

A photographic camera includes a camera body, a cartridge holder, and a shift device. The cartridge holder is capable of holding a film cartridge to be used in the photographic camera, and movable between a first position in which the film cartridge can be removed from the camera and a second position in which the film cartridge can be used in the photographic camera. The second position is aligned to the first position. The shift device shifts the cartridge holder between the first and second positions. The camera also can include a flash device, having a flashlight emitting portion, for illuminating an object to be photographed by a flash light. The camera further can include a device for determining a position of the film cartridge with respect to the camera body the cartridge holder is located at the second position.

摘要:
In the present invention, a specimen is made to flow on a metal film on a prism, and excitation light (α) is emitted in a predetermined direction. By changing the position of a reflective member that reflects the excitation light (α), and adjusting the orientation of a reflective surface of the reflective member, the incident angle (θ) is changed while maintaining a state in which the excitation light (α) that enters the prism is reflected at a specific position on the metal film. The intensity of light to be generated on the metal film is measured, and the reflective member is positioned to match the position of the reflective member and the orientation of the reflective surface when a maximum amount of light is measured.
摘要:
A drive mechanism and a drive device each comprise a driven body (1), a displacement member (2), and an SMA actuator (3) for giving a displacement force. The driven body (1) is coupled to a fixed section through a viscoelastic member (11 (11A, 11B, 11C, 11D)). A displacement output section is engaged with the driven body, and thereby a predetermined portion of the displacement member (2) for displacing the driven body in a first-axis direction is connected to the fixed section through the viscoelastic member (11 (11E, 11F, 11G, 11H)). A shape-memory alloy (SMA) actuator is used. The position of the driven body is stably and quickly controlled. Even if a shock force is exerted or even if the drive mechanism and the drive device are left in a high-temperature environment for a long time, the SMA, the drive mechanism, and the drive device do not deteriorate, the sizes and weights thereof can be reduced, and they can be easily assembled.
