Abstract: A semiconductor device including memory cells such as flip-flops, RAMs or SRAMs is powered on, and first logic signals of Hi or Lo output from the respective memory cells are obtained. A combination of the logic signals is used as a unique identification code for identifying a semiconductor device.

Abstract: A squeegee is slid over a metal mask plate so as to fill a sealing resin in a resin inflow space through a through hole, and the sealing resin, deposited on an outer surface of an electronic part that includes a vibrating part, is thermally set. A through hole that corresponds to an electronic part is formed in metal mask plate. The through hole includes a lower smaller through hole and an upper larger through hole communicating with an upper side of the lower smaller through hole, and a step portion is formed within the through hole. And a relief recess is provided in a region of a metal mask plate including at least a projected region in which an operating area is projected onto a surface of the metal mask plate opposing the touch panel in a state in which the metal mask plate covers the touch panel.

Abstract: A pair of piezoelectric substrates, the length of which is shorter than the length of one side in the longitudinal direction of the operation panel or the supporting board, is respectively fixed to one side from the diagonal position along the longitudinal direction. At the time of detecting an inputting operation, a drive voltage is applied and the entire operation panel or the supporting board is vibrated. Even when the four corners of the operation panel or the supporting board are supported by the housing for accommodating the tablet apparatus or supported by the display device so that the vibration of the four corners is restricted, since either of the pair of piezoelectric substrates, which becomes a vibration source, a feeling of inputting operation can be transmitted to an operator by the vibration, the amplitude of which is not less than a predetermined value, irrespective of the inputting operation position.

Abstract: A chemical supply system comprises, as principal elements, a chemical storage tank in which a liquid chemical for cleaning is stored in the state of its formulated concentrate, a chemical supply apparatus connected to the chemical storage tank for positively performing chemical supply, a piping system connected to the chemical supply apparatus to form a supply flow passage that is a passage for ultrapure water which the liquid chemical is to be mixed with, a pair of discharge nozzles disposed at end portions of the piping system so as to oppose surfaces of a wafer set in a cleaning chamber to supply a cleaning liquid onto the surfaces. Thereby, remarkable miniaturization/simplification of a cleaning liquid supply system including chemical tanks is intended, it is made possible easily and rapidly to compound and supply a cleaning liquid at an accurate chemical concentration, and particles or the like being generated and mixing in a cleaning liquid, are suppressed to the extremity.

Abstract: A modified styrene-based resin composition in which silicone powder is added to styrene-based resin.One can obtain styrene-based resin compositions remarkably improved in impact resistance and sliding properties, particularly in permanence during sliding. In particular, when the base material is transparent polystyrene-based resin, it was found that the present invention can provide styrene-based resin compositions having excellent impact strength, sliding properties, and transparency without spoiling their fluidity and thermostability. In addition, use of rubber modified polystyrene as styrene-based resin permits styrene-based resin compositions exhibiting well-balanced impact resistance, sliding properties, heat distortion resistance, molding properties, workability, and surface appearance of molded articles.

Abstract: A method for the purification of lactide is provided which permits lactide of high optical purity or DL-lactide of high purity to be produced from crude lactide by the removal of meso-lactide from the crude lactide. This method for the purification of lactide is characterized by causing a mixture containing L-lactide and/or D-lactide together with meso-lactide to contact with water thereby effecting hydrolysis of meso-lactide. This method can remove meso-lactide from crude lactide and produce DL-lactide and/or optically active lactide of high optical purity in high yield and, in the production of optically active lactide, can eliminate the restrictions otherwise imposed on the formation of meso-lactide. Thus, it lends itself to the simplification of the procedure for the synthesis of lactide.

Abstract: In a roller guide apparatus for guiding a steel material to be rolled into a rolling mill machine, a ratio (K/M) of an elastic constant (K [N/mm]) of the roller guide portion of a roller guide apparatus to a gradient (M [N/mm]) in a plasticity characteristic curve obtained when pressing the steel material nipped between the guide rollers in rolling is determined to be 0.5 or more, to thereby prevent the steel material from tilting between the guide rollers. As a result, dimensional accuracy in sectional shape and size of an end product can be improved, and miss-rolling can be prevented, thus producing high-quality rolled steel products without surface defects with remarkably high yield rate and productivity.

Abstract: A weft supply system of a loom using an overhead traveling truck between a package supply station and a weft supply station near the loom for holding and carrying a package wherein a package delivery device is connected to the package supply station for delivering specific types of packages to the package supply station.

Abstract: Stable gel compositions comprising a water-soluble salt of carboxymethyl cellulose wetted by or dispersed in a hydrophilic organic liquid such as glycerol, methanol acetone or the like and an aqueous solution of a water-soluble polyvalent metal salt such as potassium alum, ferric chloride, cupric chloride or the like, which are useful as bases for many preparations of medicines, cosmetics and the like.
