  • Patent number: 10497603
    Abstract: An electronic component supply body and a method for manufacturing the same, which can suppress generation of wrinkles of an adhesive sheet and is unlikely to cause pickup failure of electronic component chips to occur. The supply body includes an adhesive sheet with an adhesive layer formed with an ultraviolet-curing adhesive, a ring frame bonded onto the adhesive sheet, and electronic component chips bonded onto a first region on the adhesive sheet superimposed with the opening of the ring frame. The second cured portions that are cured by being irradiated with ultraviolet rays are provided in a part of a second region forming a bonded portion between the adhesive sheet and the ring frame. Adhesive strength in the second cured portions in a shearing direction is larger than adhesive strength in a portion of the second region other than the second cured portions.

  • Patent number: 9010171
    Abstract: An exhaust gas analyzing apparatus includes analyzer main bodies, exhaust gas introducing parts for guiding the exhaust gas from an exhaust pipe, through which the exhaust gas passes, to the analyzer main body, heaters for heating the analyzer main bodies and the exhaust gas introducing parts, respectively, and a temperature regulating mechanism for controlling the heaters to regulate temperatures of the analyzer main bodies and the exhaust gas introducing parts, and a first mode which has the temperature regulating mechanism regulate the temperatures of the analyzer main body and the exhaust gas introducing part to an analyzable temperature that is a predetermined temperature allowing a start of analysis of the exhaust gas, or a second mode which has the temperature regulating mechanism regulate the temperature of the analyzer main body to the analyzable temperature and turning off the heater for the exhaust gas introducing part can be selected.

  • Patent number: 5156082
    Abstract: A rice cooker includes an interlock that prevents the user from sliding the cooking pot out of the cooker without first disengaging internal assemblies that would otherwise be damaged. The rice cooker operates in any of three user selectable modes: a fully automatic mode in which the rice cooker measures out a user selected quantity of internally stored raw, unwashed rice, washes the rice, cooks the rice and then keeps the rice warm; a cook and keep-warm in which the cooking pot of the rice cooker is loaded with premeasured and washed rice from an external source and the rice cooker cooks the rice and keeps it rice warm; and a rice warming mode in which the cooking pot is loaded with already cooked rice and maintains it at a serving temperature. A startup routine checks that a pot is installed, that a lid is on the pot, that an upper pot cover assembly is at a required height, that a platform is in its latched position, and that a washer container is in its stowed position.

  • Patent number: 4728373
    Abstract: An improved solution and process for preparing an article of titanium or titanium alloy for cold forming reduces the peeling of the applied lubricant film. The aqueous solution contains an organic chelating compound, an aqueous organic macromolecular compound and/or a surfactant in an aqueous acidic (pH 1.5-4.5) solution of a fluoride and a soluble compound of magnesium, calcium, manganese, iron, cobalt, nickel, zinc, and/or molybdenum.

  • Patent number: 4017334
    Abstract: Disclosed is a process for treating aluminum wherein the surface is contacted with a solution containing phosphate, a tannin, titanium and fluoride prior to inking or lacquering. The process produces a coating exhibiting adhesion, color and corrosion resistance comparable to that obtained via conventional chromium-based processes without creating the pollution problems of chromium disposal.
