摘要:
A timepiece with a calendar mechanism has a drive mechanism and a time display wheel that undergoes rotation by an operation of the drive mechanism to display time information. A first date indicator is mounted to undergo intermittent rotation to display the ones place of a date. A second date indicator is mounted to undergo intermittent rotation to display the tens place of the date. A program gear wheel intermittently rotates the first and second date indicators in accordance with operation of the drive mechanism. The program gear wheel has a first program tooth disposed on an outer peripheral part of the program gear wheel for intermittently rotating the first date indicator and a second program tooth disposed in an inner peripheral part of the program gear wheel for intermittently rotating the second date indicator.

There is realized a multifunction timepiece constituted to be able to constitute a plurality of types of hand operating train wheels by only changing positions of integrating parts without changing dimensions and shapes of parts of a movement.A movement of a multifunction timepiece includes a first train wheel rotation center, and a second train wheel rotation center. A train wheel for indicating calendar information is arranged to be rotatable relative to one of the first train wheel rotation center, and the second train wheel rotation center. When the first train wheel rotation center is arranged with a train wheel for indicating calendar information, the calendar information can be indicated by a small hand rotated to move by the train wheel, when the second train wheel rotation center is arranged with a fan shape hand operating train wheel for indicating the calendar information, the calendar information can be indicated by a small hand moved in a fan shape operating train wheel.

To effectively prevent positional deviation of a battery. A hook-shaped member of a spring electrode terminal, and hook-shaped members of a spring electrode terminal are arranged in respective apices of a regular triangle to restrict movements of a battery in a direction along a cross section against the bias of a spring electrode terminal, which abuts against a negative surface of the battery. Battery abutments are arranged in respective apices of a substantially regular triangle to permit the bias of the respective spring electrode terminals to bias the battery toward the battery abutment, thus restricting positional deviation of the battery in a horizontal plane. When the battery is to be removed, a battery removal tool arranged near the hook-shaped member is inserted into a tool insertion portion to remove the battery.

To provide a jumper structure which is light-weighted and capable of reducing fabrication cost and a timepiece using the same. A jumper structure of a timepiece is constituted by integrally molding a jumping and restricting portion made of carbon nanofiber and a spring portion made of carbon nanofiber. A jumping and restricting portion of the jumper structure is thicker than the spring portion and the jumping and restricting portion includes a projected portion in a flat plate shape and in an eaves-like shape.

Disclosed is a niobium(Nb)-containing aqueous solution for use in producing a Nb-containing oxide catalyst, wherein the oxide catalyst comprises an oxide of a plurality of active component elements including Nb and is for use in a catalytic oxidation or ammoxidation of propane or isobutane in the gaseous phase, and wherein the oxide catalyst is prepared by a process comprising mixing the Nb-containing aqueous solution with (an) aqueous mixture(s) containing compounds of active component elements of the oxide catalyst other than Nb, to thereby provide an aqueous compound mixture, and drying the aqueous compound mixture, followed by calcination. The Nb-containing aqueous solution comprises water having dissolved therein a dicarboxylic acid, an Nb compound and optionally ammonia, wherein the dicarboxylic acid/Nb molar ratio (.alpha.) satisfies: 1.ltoreq.(.alpha.).ltoreq.4, and the ammonia/Nb molar ratio (.beta.) satisfies: 0.ltoreq.(.beta.).ltoreq.2. By the use of the niobium-containing aqueous solution, it has become possible to produce efficiently an oxide catalyst which, when used in a catalytic oxidation or ammoxidation of propane or isobutane in the gaseous phase, exhibits high catalytic activity, and which, therefore, can be advantageously used for producing (meth)acrylic acid or (meth)acrylonitrile in high yield.
摘要:
The invention relates to a developer cartridge for exchanging developers in an apparatus which develops an electrostatic latent image, and an image forming apparatus using the developer cartridge. The developer cartridge has a first storage room for unused developer, a second storage room under the first room for storing used developer, openings in the first and second rooms and shutters provided therewith, together with a paddling mechanism in the first storage room for moving unused developer. The image forming apparatus has an endless latent carrier, a mechanism for forming an electrostatic latent image on the carrier and a mechanism for developing the latent image on the carrier. The developer cartridge is detachable positioned to the developing mechanism and a mechanism is provided for driving the shutters of the developer cartridge for exchanging used developer with unused developer.
摘要:
In an image-forming apparatus, in which an electrostatic latent image on a photoconductive drum is developed by a toner accommodated in a container, a periodical exchange of carrier in a container is necessary. A method thereof includes steps of fitting a cartridge to the container, discharging all of an old mixture of toner and carrier from the container to the lower chamber, transferring fresh carrier from the carrier compartment into the container, and further, transferring fresh toner from the toner compartment into the container until a predetermined initial color density of the mixture is obtained.
