摘要:
A metal pipe inner surface weld-mounting apparatus having a monitoring device is constituted by an arm, a horizontal torch, a mirror, a camera and a monitoring device. The arm has a supported base end portion, which is horizontally extended. The horizontal torch is attached to a leading end portion of the arm. The weld-mounting is performed on an inner surface portion of a metal pipe supported rotatably around a horizontally extending axis while at least one of the metal pipe and the horizontal torch is moved in a direction of the axis. The mirror is attached to the leading end portion of the arm. The camera is disposed in a position separated from the mirror for picking up an image of weld-mounting beads in a neighborhood of arc light of the horizontal torch through the mirror. The monitoring device monitors a condition of the weld-mounting.

The multi-layered heat resistant metal tube is disclosed. This tube has excellent anti-coking characteristics and is suitable for use under the conditions where carbon tends to deposit and accumulate thereon due to contacting with hydrocarbons at a high temperature. The tube is made by forming weld-mounted overlaid layer of Cr—Ni alloy by building-up welding over the inner surface and/or the outer surface of a substrate tube made of a heat resistant metal. The Cr—Ni alloy comprises 35% by weight or more of Cr and satisfies the relationship: Ni(w%)≧0.5Cr(wt %). Building-up welding is preferably carried out by PPW (Plasma Powder Welding) in which the filler metal is supplied in the form of powder.

According to one embodiment, an image forming apparatus includes a photoreceptor, a charging unit, an exposure unit, a developing unit, a transfer unit, a fixing unit, an environment detecting unit and a control unit. The charging unit includes a charger and a static eliminator. The charger contacts with a surface of the photoreceptor and charges the surface to a first voltage. The static eliminator contacts with the surface and discharges the surface to a second voltage. The environment detecting unit detects an environmental data. The control unit controls the first voltage based on the environmental data.

An image forming apparatus includes: an image forming section; a discharger for discharging and guiding the copying paper to an outlet; and a controlling section for operating the image forming section, based on an image forming instruction from an operation section. A data fetching section fetches first image data on a plurality of pages and second image data on a plurality of pages. The operation section accepts, as the image forming instruction, a sheaf-unit sorting instruction which includes a predetermined number of copies of each of the first image data and second image data and sorting of the copies. The controlling section, based on the sheaf-unit sorting instruction executes, for the predetermined number of copies, an operation of guiding the first and second sheafs of copying paper, in sequence, to the outlet so that the first sheaf and second sheafs of copying paper are piled in order.

A metal pipe expander which is inserted into a metal pipe and driven to move in the axial direction of the metal pipe by a liquid pressure has an expanding section and a pressure receiving section. The expanding section has a conical portion of which a small diameter portion is directed to a front side. The pressure receiving section has a cup shaped portion opened to the rear side, the outer surface of which is in slide contact with an inner surface of the metal pipe after it is expanded in diameter. The pressure receiving section is provided at a rear end of an expanding section.

A gas shielding apparatus comprising a main gas jacket having induction heating means, and front gas jacket and rear gas jacket integrally disposed at supply side and discharge side of a member to be bonded or a member to be heated of the main gas jacket, wherein gas shielding is achieved by setting the internal pressure of the main gas jacket lower than the internal pressure of the front gas jacket and rear gas jacket, so that the holding time of the shielding gas jacket in the main gas jacket becomes long.
摘要:
The present invention is applied to an apparatus in which laser light corresponding to images to be formed scans a photoconductor at an approximately constant velocity in order to write a plurality of images arranged along a scanning direction of the laser light, in parallel. A scanning velocity of the laser light is varied to adjust a writing position of the image to be written last among the plurality of images by the laser light.

An imaging lens extending apparatus includes a circuit substrate mounting an imaging sensor device; a tubular guide part; a tubular rotary body that includes a switching lever; a macro core; an imaging lens group fit to the macro core; a wave washer; and a cover which is affixed to the circuit substrate. The tubular rotary body is rotatably fit to the tubular guide part. An annular groove of the macro core slidably fits with a tip part of the tubular guide part. Inclined cam surfaces are provided to an upper surface of the tubular rotary body, having heights that gradually changes along the circumferential direction. Rotational stop projections on the outer circumference of the macro core slidably fit within corner brackets of the pedestal. Rotation of the switching lever causes axial movement of the imaging lens group without rotating the imaging lens group.
