摘要:
A developing device includes a developer bearer to carry, by rotation, developer to a developing range, a casing including a developer container to contain the developer and housing the developer bearer, a gap retainer adjacent to the developer container and downstream from the developing range in a rotation direction of the developer bearer, an opposing wall opposing an end face of the gap retainer in an axial direction of the developer bearer, a first seal disposed between the end face of the gap retainer and the opposing wall, and a contact portion disposed adjacent to an end portion of the gap retainer in the axial direction of the developer bearer. The gap retainer secures a predetermined gap between the developer bearer and the gap retainer. The contact portion contacts, via a second seal, the gap retainer in a direction intersecting the axial direction of the developer bearer.

A developer container includes a container body, a rotary shaft, a rotary stirrer, and a flexible blade. The container body contains developer and has a discharge port. The rotary stirrer includes a rotary support and rotates about the rotary shaft to stir and transport the developer. The rotary support includes a base end rotatable integrally with the rotary shaft, a free end spaced away from an inner wall of the container body, and a holding surface provided at the free end or at a position shifted toward the rotary shaft away from the free end. The holding surface is parallel to or inclined relative to a rotation direction of the rotary support. The flexible blade includes a base end portion held on the holding surface and a distal end to contact the inner wall and transport the developer to the discharge port.

A 1.55 μm band dispersion shifted optical fiber is provided which has a low loss and low dispersion slope. A core region “a” is heavily doped with GeO2 . A core region “b” is composed of pure SiO2 glass. A cladding section is arranged around the core region. The cladding section has a lot of holes extending in the longitudinal direction of the optical fiber. The holes of the cladding section are not located at random, but have a honeycomb structure composed of regular hexagons which have a side length of Λ, and serve as a primitive lattice. The center of the core section has a region having a refractive index higher than that of the periphery of the core section. The core section has the refractive index distribution in which the group velocity dispersion at the operation wavelength of the region becomes the normal dispersion.

The present invention provides an active control type noise reducing device that is disposed at a sound barrier and with which can be obtained an excellent noise reduction effect with respect to moving sound sources. Linear array of flat loudspeakers are arranged in ascending order from an incoming side of automobiles towards an outgoing side. Delay times of 0, τ, 2τ, . . . , 8τ are respectively given in the arrangement order to the linear array of flat loudspeakers. By delaying signals in correspondence to the arrangement order, the wavefront of a control sound can be slanted in a diagonal direction. Namely, “line sound sources”, where sound sources are linearly arranged, arc pseudo-realized.

A DPF and a SCR catalyst are provided in an exhaust pipe, and a urea solution addition valve is provided between the DPF and the SCR catalyst for performing addition supply of urea solution into the exhaust pipe. In a urea solution supply system, the urea solution of prescribed concentration is stored in a urea solution tank, and a urea solution pump is provided in the tank. A urea solution supply pipe is connected to the urea solution pump. A part of the urea solution supply pipe is structured as a compound pipe structure defining two passages. One of the two passages serves as a urea solution passage, and the other one serves as an engine coolant passage.

The present invention relates to a relay device enabling efficient management of a voice message and a caller to wait for transmission of the voice message in a short time. The relay device is located at a boundary between an existing telephone network and an IP network, converts and relays a voice signal and an IP packet. The relay device comprises a receiving unit receiving voice source data into which a voice message is digitized, a packet processing unit converting the received voice source data into a voice source data packet as the IP packet, a storage unit storing the converted voice source data packets, and a transmitting unit transmitting, when transmitting a designated voice message to a designated destination, the voice source data packet corresponding to the designated voice message among the stored voice source data packets.
摘要:
A magnetooptical recording apparatus that records information by applying a magnetic field from a magnetic head while irradiating a light beam onto a magnetooptical disk from an optical pickup. The apparatus includes an optical pickup, a magnetic head having a slider that moves in a radial direction of the magnetooptical disk together with the optical pickup and is abutted against a recording surface of the magnetooptical disk and first and second elastic members that support the magnetic head.

A catalyst for cleaning exhaust gas comprises a carrier and a coated layer applied onto the surface of the carrier which comprises an aluminum oxide, a cerium oxide, a zirconium oxide, a nickel oxide, an alkaline earth metal oxide and a noble metal catalytic component. The catalyst can be prepared according to a method which comprises the steps of coating the surface of a carrier with a slurry which comprises active alumina, a cerium compound, a zirconium compound and a nickel compound, drying the coated carrier and then calcining it to complete the carrier, then impregnating the carrier with a solution comprising a catalyst component of a noble metal, drying, then immersing it in a solution of an alkaline earth metal compound, drying the immersed carrier and then calcining the carrier. The catalyst for exhaust gas-cleanup is highly sensitive to HC and CO around the theoretical mixing ratio and within the rich-region and is excellent in durability.

This invention relates to a writing instrument wherein a temporary ink storage member made of a synthetic resin injection molded article is sandwiched between a pen tip and an ink tank. In the present invention, a flange portion for fitting to a predetermined apparatus, which is positioned around an outer peripheral portion of the temporary ink storage member, is formed integrally with a shaft made of a synthetic resin injection molded article. In embodiments of the invention, the temporary ink storage member is made flexible, the shaft is made of a material which is softer than that of the tip holder, and the tip holder is used as a writing thickness display member. The temporary ink storage member can be used as an ink color display member and a cap is used as an application display member. In other embodiment, the cap can be fitted selectively in accordance with types of writing instruments.
