摘要:
In a volume determination process, a slit pattern is projected obliquely downwardly, or slit patterns are projected obliquely downwardly and upwardly, onto an article which is at rest or in motion. The slit pattern or patterns are in the form of a parallel stripe pattern or a grid pattern. The surface or surface onto which the slit pattern or patterns are projected are imaged by a television camera, and the heights of slit positions on the article are computed on the basis of the image or images picked up by the television camera. The volume of the article is computed on the basis of the computed heights of the slit positions. The weight of the article can be derived by multiplying the volume by the specific gravity of the article. It is determined whether there is a surface flaw or not by determining whether differentials of the slit pattern or patterns are discrete or not.

A heat exchanger such as a radiator for an automotive engine is produced by fixing lengths of flattened tubes and corrugated fins to each other by brazing within a furnace. The flattened tube is formed by bending a strip and welding the opposing edges of the bent strip to each other to form a tube of a substantially circular cross-section, and applying pressure to the tube along the weld line to form the flattened tube while depressing the tube wall along the weld line to form an elongated recess or groove along the weld line. Then, a brazing material is applied to the outer surfaces of the flattened tube to cover and fill up any minute weld defects which may exist in the flattened tube whereby the weld defects are repaired.

Presetting counter device for control of single or repeated actuation of a piece of equipment permits stopping of equipment action during continuous repeat action thereof if required, and always resets a display means for an indication of the number of times the device is required to be actuated to "1" when the equipment is thus stopped and after single or repeated actuation of the equipment, whereby manual resetting action by a user is unnecessary. As the device requires manual actuation only of a resetting switch, an initial count means for specifying a required number of actions during actuation of the equipment, and a start switch, equipment control with the device is extremely simple.

The present invention relates to a PFC switching power supply which can perform polarity determination and voltage detection of AC voltage without using a DC isolator such as a transformer.Included are: a power factor correction section which rectifies AC voltage inputted, outputs DC voltage to a load and corrects a power factor; an input voltage detecting section which outputs L pole detected voltage and N pole detected voltage; and a switching controller which controls the operation of the power factor correction section. An AC waveform generating section of the switching controller generates an AC waveform. The switching controller generates a drive pulse having a frequency and a duty ratio varying depending on AC waveform, whereby a predetermined level of the DC output of the power factor correction section is maintained and in addition, the power factor is corrected.

The present invention provides a method for producing a separator for nonaqueous electrolyte electricity storage devices. The method allows: avoidance of use of a solvent that places a large load on the environment; and relatively easy control of parameters such as the porosity and the pore diameter. The production method of the present invention includes the steps of: preparing an epoxy resin composition containing an epoxy resin, a curing agent, and a porogen; forming a cured product of the epoxy resin composition into a sheet shape or curing a sheet-shaped formed body of the epoxy resin composition, so as to obtain an epoxy resin sheet; removing the porogen from the epoxy resin sheet by means of a halogen-free solvent so as to form a porous epoxy resin membrane; and drying the porous epoxy resin membrane by heat-roll drying.

Methods and apparatus are disclosed for etching flexible glass sheets (13) in which the sheets (13) are transported in a near vertical orientation past non-contact, liquid-ejecting bearings (3) which apply an etching solution (e.g., an aqueous NaF/H3PO4 solution) to the sheets (13). In certain embodiments, the uppermost liquid-ejecting bearing (3) is above the top edge of the sheet (13) and thus is able to apply etching solution to the top of the sheet. In other embodiments, a top shower (11), which includes a set of spray nozzles (21) located above and distributed along the length of the apparatus, is used to apply etching solution to the top of the sheet (13). Using the disclosed methods and apparatus, glass sheets (13) produced by a fusion process are provided which have areas greater than five square meters and average surface roughness values in the range of 0.5 nanometers to 1.1 nanometers.
