Abstract:
A developing device includes a developer carrier, a developing unit housing which rotatably supports the developer carrier, a side seal member which comes into slidable contact with both ends of the developer carrier, a sheet-like elongated seal member which extends in the axial direction of the developer carrier so as to come into slidable contact with the developer carrier, a side seal attachment surface which is formed in the developing unit housing and to which the side seal member is attached, and a support portion which is formed in the developing unit housing and protrudes toward the developer carrier from the side seal attachment surface to support the elongated seal member. The elongated seal member is attached onto the support portion in a state where both ends thereof overlap the side seal member and are opposite the side seal attachment surface.

Abstract:
The invention relates to a package starting control device determining a moment and a sequence of starting a package corresponding to an individual wavelength to be wavelength-division-multiplexed in a wavelength division multiplex transmission device. An object of the invention is to provide a package starting control device capable of effectively increasing or decreasing the number of wavelengths at low cost without changing a basic structure drastically. The package starting control device is constructed such that operational states of optical modules that generate optical signals wavelength-division-multiplexed into wavelength division multiplexed optical signals are monitored, the optical signal output by packages that generate the optical signals wavelength-division-multiplexed into the wavelength division multiplexed optical signals during a period when any of the operational states is not in a steady state is restricted and the restriction of the optical signal output by one package of the packages each time the period elapses is released.
Abstract:
A microvolume liquid dispensing device capable of automatically dispensing a predetermined volume of a microvolume liquid has been provided. Because one surface of a main channel (13) is gradually varied from a hydrophobic property to a hydrophilic property, a microvolume liquid (A) placed in the main channel (13) can be automatically transported. One surface of a side channel (14) is of a hydrophilic property, so that a potion of the microvolume liquid (A) can be automatically guided to the side channel (14).
Abstract:
In an image taking apparatus according to the present invention, focus adjustment is performed based on image information in a focus adjustment area within a captured image in response to a movement instruction from a user as well as a focus adjustment mode switching instruction from the user. When detecting an instruction to switch to a position non-fixed focus adjustment mode, an initial position of the focus adjustment area in the position non-fixed focus adjustment mode immediately after mode switching is determined based on a position of a representative point of the focus adjustment area immediately before the mode switching.

The double collecting pipe 21 is comprised of an inner pipe 21-1 and an outer pipe 21-2, which are connected integrally to each other. In a space formed between the inner pipe 21-1, the outer pipe 21-2, and a ring-shaped stainless steel cushion member 22-2, a tubular cushion member 22-1, which is thermally expanded and foamed, is arranged as a restricted cushion structure.
Abstract:
A vehicle navigation apparatus displays an expressway guide diagram indicating the names of plural exits at which a travelling vehicle can exit an expressway and the distance and estimated arrival time to each of the exits. The expressway guide diagram includes a map display for indicating a display of a surrounding-area map of an exit. When the map display is operated, the display scale of the surrounding-area map is determined so as to contain a predetermined number of representative facilities, and the surrounding-area map is displayed on a display device according to the display scale. Therefore, with respect to each exit at which the vehicle can get off the expressway, a map based on the proper display scale corresponding to the positional relationship between each exit and facilities can be displayed.
