    摘要： To provide a manufacturing method of the semiconductor IC device having fine-structure connecting holes or trenches with high dimensional precision. There is the following step of the operation: a hook-shaped hard mask made of polysilicon film 18 and polysilicon film 20a is formed on the surface of silica film 17 for forming connecting holes 21 accommodating plugs that perform an electrical connection with the lower portion of the lower electrode of the capacitor in the COB-type memory cells, with the hook-shaped hard mask being used as an etching mask in selective etching so as to form connecting holes 21 on silica film 17 and silica film 15 below it.

    摘要： If cylinder bores formed in a caliper parallel to each other are communicated together through a pipe casted in the caliper, the pipe tends to come out of the caliper into a cylinder bore. A separate short pipe is provided to communicate the cylinder bores. The pipe has an engaging portion so as to extend in a diametric direction of the short pipe to prevent longitudinal shift of the short pipe. The engaging portions can be provided easily by forming a recess or a protrusion on the outer periphery of the pipe and casting the pipe in the caliper.

    摘要： A controlling member (a controlling pin 10) is inserted through an insertion hole 7 of a mold 1 and projected into a cavity 6. After a pipe P as an insert member is arranged at a predetermined position in the cavity 6, the pipe P is held in the cavity 6 by inserting a tip of the controlling pin 10 into a hole h of the pipe P at the end p1, or by inserting the end p1 of the pipe P into a cave 21 of the controlling member. A molten aluminum alloy is then poured through a gate 5 into the cavity 6 under such the condition, to enclose the pipe P with the aluminum alloy. Dislocation of the pipe P caused by kinetic and thermal energies of the poured aluminum alloy is suppressed by the controlling pin 10 or block 20 at the end p1. Since the enclosed pipe P has its end p1 opened at a predetermined position, a cast product obtained in this way can be used as a brake caliper or the like having an inner hydraulic circuit.

    摘要翻译： 控制构件（控制销10）通过模具1的插入孔7插入并突出到空腔6中。在作为插入构件的管P布置在空腔6中的预定位置之后，管P是 通过将控制销10的尖端插入端部p1处的管P的孔h中，或者将管P的端部p1插入到控制构件的洞穴21中而保持在空腔6中。 然后在这种条件下，将熔融的铝合金通过浇口5浇注到空腔6中，以用铝合金包住管道P. 通过浇注铝合金的动能和热能引起的管道P的位移由端部p1处的控制销10或块20抑制。 由于封闭管P的端部p1在预定位置处开口，所以以这种方式获得的铸造产品可以用作具有内部液压回路的制动钳等。

    摘要： A heat exchanger comprising an outer tube, one or more inner tubes disposed with interstice within said outer tube, and a spiral element extending longitudinally within said inner tube(s). The spiral element is made up of a plurality of unit elements connected together with a connection angle of 0.degree.. Each of the unit elements has a twist angle of 180.degree., with the direction of twist being reversed from one to a neighboring unit element. Channeling phenomenon is effectively avoided. Heat exchange medium with Rheynolds number Re>10.sup.4 is suitable.
