  • Publication number: 20160116503
    Abstract: Provided is an electronic device handling apparatus capable of increasing the number of simultaneous measurements while suppressing the increase in cost. An electronic device handling apparatus, which moves bare dies relative to a probe card, includes: a thermal head which includes a plurality of holding regions each of which holds the bare die and has openings; at least one lift unit which is movably held by the thermal head so as to correspond to the holding regions and is able to advance and retreat through the openings; a moving device which moves the thermal head; and a fixed arm which is able to support the one lift unit.

  • Patent number: 9150575
    Abstract: A compound represented by the general formula (I) or a pharmacologically acceptable salt thereof has an excellent LCAT-activating effect and is useful as an active ingredient in a therapeutic or prophylactic agent for arteriosclerosis, arteriosclerotic heart disease, coronary heart disease (including heart failure, myocardial infarction, angina pectoris, cardiac ischemia, cardiovascular disturbance, and restenosis caused by angiogenesis), cerebrovascular disease (including stroke and cerebral infarction), peripheral vascular disease (including diabetic vascular complications), dyslipidemia, hypo-HDL-cholesterolemia, or renal disease, particularly, an anti-arteriosclerotic agent, wherein R is an optionally substituted aryl group or an optionally substituted heteroaryl group.

  • Publication number: 20130137899
    Abstract: In this process for producing a fluorine-containing sulfonylimide compound, a process for producing a fluorine-containing sulfonylimide compound ((Rf1SO2)(Rf2SO2)2N.M) is employed that comprises a first step of obtaining a reaction liquid by reacting a perfluoroalkylsulfonyl fluoride (Rf1SO2F) with ammonia, a second step of obtaining a mixture containing an alkaline metal salt of a perfluoroalkylsulfonamide (Rf'SO2NH.M) by reacting the reaction liquid with at least one type of alkaline metal compound selected from among hydroxides, carbonates and bicarbonates of alkaline metals M of either Li, Na or K, and a third step of reacting the mixture with a perfluoroalkylsulfonyl halide (Rf2SO2X), wherein Rf1 and Rf2 represent linear or branched perfluoroalkyl groups having 1 to 4 carbon atoms, and X represents fluorine or chlorine.

  • Patent number: 8178731
    Abstract: An object of the present invention is to provide a process for producing high-purity hydroxytriphenylenes in which not only inexpensive raw materials can be used but also no complicated steps of deprotection such as dealkylation, and reduction and the like are necessary, and which is thereby advantageous in industrial production. Also there is provided a novel crystal of 2,3,6,7,10,11-hexahydroxytriphenylene monohydrate, which has satisfactory thermal stability. The process for producing a compound represented by the general formula (2) is characterized by reacting a compound represented by the general formula (1) in the presence of a metal oxide comprising a metal selected from trivalent iron, pentavalent vanadium and hexavalent molybdenum and of a nonvolatile strong acid: wherein, Rs are each independently a hydrogen atom, a halogen atom, an alkyl group having 1 to 3 carbon atoms or an alkoxy group having 1 to 3 carbon atoms.
