摘要:
An imaging method is disclosed that is implemented in an image forming apparatus for forming a tone pattern on a recording medium by forming an arrangement of dots on the recording medium. The arrangement of dots is formed on the recording medium by jetting a recording liquid from a recording head while moving the recording head in a main scanning direction a plurality of times and intermittently conveying the recording medium in a sub-scanning direction that perpendicularly intersects the main scanning direction. The imaging method involves forming the arrangement of dots such that dots belonging to a first group that are consecutively aligned in a base tone direction and dots belonging to a second group that are consecutively aligned in the sub scanning direction are respectively formed in non-consecutive order on the recording medium.

摘要:
An endoscope system with an endoscope, a TV monitor, and a peripheral device separate from the endoscope and the TV monitor is provided. The endoscope includes an objective optical system and an image pickup device that converts an image formed by the objective optical system into a video signal which can be indicated in the TV monitor. The endoscope also includes a signal generator that generates a control signal to be supplied to the peripheral device so as to control the peripheral device. Additionally, the endoscope includes a transmitter that transmits the video signal to the TV monitor while no control signal is generated by the signal generator. The transmitter also transmits, as a radio signal, both the video signal and the control signal to the TV monitor and the peripheral device upon the control signal being generated by the signal generator. The endoscope also includes a signal adder that adds the control signal to a blanking interval of the video signal to output the video signal added with the control signal to the transmitter.
摘要:
Desulfurization is carried out by blowing CaO into molten iron, and a gas mixture of an inert gas and a hydrocarbon gas is used as a carrier. The ratio of the hydrocarbon gas to the desulfurizing agent is maintained in the range of from about 2.0 to about 50 Nl/kg. This desulfurizing method improves the desulfurization efficiency of the desulfurizing agent, increases the productivity of the desulfurizing process, and reduces the amount of slag generated in the desulfurizing process. Alternatively, a desulfurizing flux is blown into the molten iron together with a carrier gas comprising a gas mixture of an inert gas and a hydrocarbon gas or an inert gas alone at the start of desulfurization. The hydrocarbon gas in the carrier gas is increased, is added, or the unit gas is replaced by the hydrocarbon gas at adequate timing, whereby the desulfurization efficiency is improved.
摘要:
A process for desulfurizing a molten iron alloy in which a desulfurizing agent is applied to the molten iron alloy under agitation. Concurrently, a gas containing a hydrocarbon gas is blown onto the bath surface of the molten iron alloy, or a substance generating a hydrocarbon gas is added to the bath surface.

A blower nozzle (30) and a vacuum nozzle (40) extending in parallel with each other are connected to a main body (10) housing therein a fan (19) and a motor (20). The main body (10) is provided with a dust bag (50). In a vacuum mode, air is directly sucked from the vacuum nozzle and is introduced into the dust bag by the rotation of the fan. In a blower mode, the air similarly sucked from the vacuum nozzle is directed toward the blower nozzle.

Method and top blowing lance for decarburization refining chromium molten ferrous metal in which dust formation and chromium loss due to oxidation are suppressed and high productivity is achieved. Decarburization of molten ferrous metal is achieved by blowing gaseous oxygen into the molten metal in a refining furnace provided with a top blowing lance having a plurality of gas blowing nozzles at the tip of the lance. The gas blowing nozzles include at least one sub-nozzle provided at or near the lance axis and a plurality of main nozzles at an outer section of the lance. Blowing refining is carried out with oxygen flow from a plurality of the main nozzles at a flow rate higher than that from the sub-nozzle(s), when the carbon content in the molten metal is about 1 wt % or more.
摘要:
A router for engaging a workpiece to be cut has a housing and a motor operable to rotate a drive shaft. A first fence is adjustably secured to the housing, and has a first planar surface oriented substantially parallel to the drive shaft axis. The first fence is adjustable to move the first planar surface toward and away from the drive shaft axis. A second fence is slidably attached to the first fence. The second fence has a second planar surface oriented substantially perpendicular to the drive shaft axis, and has an opening for receiving the bit therethrough. The second fence is slidable to move the second planar surface toward and away from the drive shaft to allow the bit to be plunged through the opening to cut the workpiece. The first and second planer surfaces are sufficiently sized so that either the first or second planer surface can be used as a base for the router with the router center of gravity located directly above the planer surface that is used as the router base.
