摘要:
A non-contact laser triangulation scanning apparatus for generating a three-dimensional image of the surface of an object based on the 3D surface position and surface contrast information. The apparatus comprises a laser source, a first optical unit, a second optical unit, a photosensitive positional detector having a plurality of sensor elements, and an incident light measurement device. According to generated timing signals having a predetermined time interval, a reset timing of the sensor elements of the photosensitive positional detector is controlled. The incident light measurement device measures an amount of a certifying laser light after one timing signal. An amount of a measurement laser light is determined dependent on the measured amount of the certifying laser light. The three-dimensional image is generated by combining position data derived from signals of the positional detector with contrast data derived at least from signals of the incident light measurement device.

摘要:
A three-electrode electrolyzer cell is described that can produce either alkaline water or acid water, by selecting polarity and ion exchange membrane type. The cell has a middle chamber and two side electrolysis chambers bordering the middle chamber. Each of the side electrolysis chambers is separated from the middle chambers by a membrane, which is the same on both sides. Porous electrodes are placed on the electrolysis side of each membrane. The electrolysis chamber electrodes are placed next to the membranes, and they are both charged with either positive or negative polarity at the same time. The electrode in the middle chamber is charged with the opposite polarity to the electrolysis chamber electrodes. Each of the electrolysis chambers has inlets and outlets for flowing a solution to be electrolyzed through the cells. The electrolyte solution is in the middle chamber. It is not circulated, or is only circulated to replenish electrolytes or remove gases. The electrolyzer of the invention is significantly more efficient than prior art electrolyzers, when only one type of water (acid or alkaline) is required.
摘要:
An electrode structure for electrolysis of water comprising a sheet formed from an electrically non-conductive material whose both sides are laminated with a sheet formed from an electrically conductive material, and a plurality of holes having been bored through said laminated sheet. A net shape sheet of an electrically non-conductive material or an electrically conductive material can be used as the electrically non-conductive sheet or as the electrically conductive sheet. After setting one said electrically conductive sheet as an anode and another one as a cathode, the sterilization of water by electrolysis is carried out by immersing at least a portion of the electrode structure into water, and applying an electric voltage across the anode and the cathode.

This invention relates an electrode composition for electrolysis of water, which is comprised of a panel of which one surface is made from electric conductive material and another surface is made from non electric conductive material. Plural holes are bored through said panel, and two said panels are arranged so as to hold a diaphragm between the surface of non-electric conductive material of each panel. And electrolysis reaction occurs at outer side of an anode and cathode of said electrode composition.
摘要:
In an apparatus for producing acidic electrolyzed water, the use of a protection membrane having slits or other discontinuities allows the protection of a permeable membrane, such as an anion-permeable or anion-selective membrane, from chlorine generated by the electrolysis. The protection membrane further preserves the electrical conductivity of the membrane and electrode assembly, because of a venting action of trapped gas and fluid through the slits. The protection membrane is useful both in three chambered electrolyzers and in two chambered electrolyzers. The preferred protection membrane has slits formed by overlapping strips of fabric or the like. The preferred fabric is a non-woven fabric.
摘要:
An improved device and method for the creation of acidic electrolyzed water is described. The device has an flow-through anode chamber and a static cathode chamber. The static cathode chamber contains a fixed amount of salt-containing electrolyte, which is renewed as needed. The flow rate of water through the anode is restricted to a range of about 5 to 40 ml per ampere of current passed through the electrode. Electrolyzed water flowing from the anode is diluted to obtain the desired concentration of hypochlorous acid, and is collected in a tank or other vessel. The electrolysis reaction is terminated when a preset amount of current has passed through the anode. Water circulation may be one pass or recycling. In a preferred embodiment, the membrane is anion-selective. Preferably, the membrane and the electrodes are integrated into a preassembled format that can be attached to the anode and cathode compartments via flanges or similar devices allowing quick replacement of an electrode assembly in an electrolyzer. The anion-permeable membrane can be protected by a protection membrane, in which are provided slits or other discontinuities to allow venting of gas.
