摘要:
A process for producing a glass having a rod refractive index distribution, which includes pressing a glass at a temperature below the glass transition temperature to form a glass having a density increased towards the surface layer thereof, or alternatively includes heating a glass at a temperature around the transition temperature at the lowest to prepare glass having a uniformly enhanced density and heating the treated glass under a pressure lower than the applied pressure at a temperature below the glass transition temperature of the glass to prepare a rod glass having a density increased towards the central portion.

摘要:
A virtual node ID control unit controls a virtual node ID that specifies a plurality of nodes as a single group. A status control unit controls node statuses that include information indicating the operating statuses of each individual node belonging to the group, and selects an operating mode that is either a priority mode. The local mode operates as an active node, or a standby mode, and the local mode operates as a standby node. A transmission/reception control unit controls the operation of the local node in accordance with the operating mode selected by the status control unit.

An energy beam method and apparatus for processing a workpiece is accomplished by making the energy density per unit time and unit area of the energy beam proportional to the traveling velocity of the workpiece. This is accomplished by adjusting the frequency, irradiation power, or duty cycle of the energy beam. The travel velocity of the workpiece is measured by using a linear scale to generate pulse signals, calculating a traveling velocity based on the pulse signals and generating a pulse signal, dividing the pulse signals output by the calculation step, and generating a trigger signal in response to the pulse signals created by the dividing step to drive an energy beam irradiation device (such as a laser generator) to output the energy beam.
摘要:
A composition of at least one member selected from the group consisting of sodium fluoride and calcium fluoride and optionally containing kaolin is powerful adhesive for ceramic articles which is used by interposing the adhesive intimately between the opposed surfaces for union of the ceramic articles and heating the adhesive to a temperature equal to or higher than the decomposition temperature of the fluoride used.

Adhesion of two silicon nitride parts is accomplished by interposing a layer of calcium fluoride or a mixture of calcium fluoride with kaoline between the two silicon nitride parts and heating the resultant interposed layer.

An intaglio printing method for transferring a resin to a print receiving material, using an intaglio printing master having portions depressed in a printing shape below the surface of the printing master, includes the steps of: filling a resin paste comprising a resin in the depressed portions of the printing master, bringing the printing master, with the resin paste being filled in the depressed portions thereof, into close contact with the print receiving material, hardening the resin in the resin paste in the depressed portions of the printing master, and separating the printing master from the print receiving material so as to transfer the hardened resin in the depressed portions of the printing master to the print receiving material. An apparatus for carrying out this intaglio printing method is proposed. By use of the apparatus, for instance, an elastic and durable spacer free from fatigue destruction for a touch panel is can be prepared in a circulation process.
摘要:
A method of preparing a plastic mask for paste printing with a plastic sheet being provided with an area containing a predetermined pattern including one or more through-holes is carried out by the steps of bringing the plastic mask provided with electroconductive material on at least one surface into close contact with a printing material while applying an electrical ground potential to the electroconductive material and then using the mask for paste printing by spreading and pressing a past to cause it to pass through any of the through-holes forming the predetermined pattern for deposit on the printing material and then removing the mask from the printing material to leave the paste printing pattern.
