Abstract: A stacked-type, multi-flow heat exchanger includes a first header pipe and a second header pipe formed opposite the first header pipe. The heat exchanger also includes a plurality of heat transfer tubes extending between the first header pipe and the second header pipe, such that the first header pipe and the second header pipe are in fluid communication via the heat transfer tubes. The heat exchanger further includes a plurality of fins alternately stacked with the plurality of heat transfer tubes. Moreover each of the ends of the first header pipe includes a first tapered portion having a reduced diameter relative to a diameter of a center portion of the first header pipe. In another embodiment, each of the ends of the second header pipe includes a second tapered portion having a reduced diameter relative to a diameter of a center portion of the second header pipe.

Abstract: A liquid crystal cell is made by filling a nematic liquid crystal between a pair of glass substrates having a transparent electrode on each confronting inside surface, a twisted retardation film or an ordinary retardation film being disposed as a birefringence layer on the visible side of the liquid crystal cell, and an absorption-type polarizing film being disposed on the outside thereof. On the opposite side to the visible side of the liquid crystal cell, a reflection-type polarizing film, a translucent absorbing film and a back light are disposed in that order. Through the above configuration, a bright reflection-type color display using outside light and a transmission-type color display using a back light can be obtained.

Abstract: A liquid vaporizing apparatus includes a container for holding a liquid at a constant temperature with a temperature adjustment unit and a gas that does not react with the liquid is bubbled through the liquid in the container to vaporize the liquid. The container for holding the liquid has an internal space above the liquid and a second temperature adjustment unit for controlling the temperature of the internal space separately from the temperature of the liquid in the container. Since the internal space is maintained at a constant temperature, higher than the temperature of the liquid, the quantity of the vaporized liquid produced is stable.

Abstract: An electrolytic capacitor having a capacitor element which includes a plurality of foils, and having also an electrolyte, wherein the plurality of foils and the electrolyte are contained in a cylindrical case having on one of its end surfaces a pair of lead terminals to connect to the capacitor element and on another of its end surfaces an explosion preventive vent is electrically aged. The electrolytic capacitor is placed onto a support table so that the capacitor's end surface having the lead terminals is not below the capacitor's end surface having the explosion preventive vent. Each one of the pair of lead terminals is connected to a respective one of a pair of electrode sections. An electric voltage is then applied across the pair of lead terminals through the pair of electrode sections.
