Abstract: A vibration damping equipment for a torsional damper comprises a hub plate, side plates, a torsion spring, a friction block, and low rigidity members. Each low rigidity member is interposed between the hub plate and each friction block to be adjacent to each other through a partition of the hub plate. The low rigidity members are connected to each other on at least one axial side of the partition.

Abstract: A leak diagnosis system is provided for diagnosing a leak condition of an evaporative emission control system for an internal combustion engine. The leak diagnosis system receives a signal indicative of a pressure in the evaporative emission system and obtains a converged limit negative pressure in the evaporative emission control system when the evaporative emission control system is communicated with the operating engine. The leak diagnosis system diagnoses a leak condition by comparing the converged limit negative pressure with a leak decision value.

Abstract: A highly sensitive, quick recovery differential microcalorimeter includes two matchingly formed and cooperatingly disposed flow channels. Each flow channel has two inlets, at least one mixing assembly connected to each fluid inlet, a fluid outlet connected to each mixing assembly, at least one heater element surrounding at least a portion of each fluid outlet, and a plurality of sensors surrounding at least a portion of each fluid outlet. Each of the mixing assemblies includes a mixing chamber and at least one entry manifold connected to a fluid inlet and having a plurality of ports which connect to the mixing chamber.

Abstract: A semiconductor memory device according to the present invention comprises a memory cell having one transistor and one stacked capacitor. The stacked capacitor is stacked on the surface of a semiconductor substrate. Further, the stacked capacitor has a structure extending on a gate electrode and a word line through an insulating layer. A lower electrode layer of the capacitor had various concave/convex shapes, i.e. step portions and projecting portions formed on the surface thereof. These shapes are made by employing various etching processes. The lower electrode layer has such various concave/convex shapes formed thereon, so that a surface area and capacitance of the capacitor can be increased.

Abstract: A rotary wavy motion type engine is disclosed, and the engine includes: a center housing 1 and side housing 2,2'. The center housing 1 is provided with an exhaust hole 1', and the center and side housing form a frame and an internal chamber. A disc shaped piston 4 having supporting 4a,4b is supported within a pair of arcuate recesses 2', 2a' of the side housings 2,2a. An inclined eccentric shaft 3 is rotatably secured to the disc shaped piston 4, and the other end of the shaft 3 is connected to an output shaft. The disc shaped piston 4 defines left and right chamber 5, 6, and nutation members 23,23' are attached upon and under the disc shaped piston 4 in such a manner that they should define an intaking compressing room 8 and a pressure releasing room 9. All of the above components are arranged in such a manner as to produce twisting wavy motions in the disc shaped piston.

Abstract: An apparatus for smoothing the surface of a monocrystal ingot comprising a center axis finding device, an external cylindrical grinding unit, an ingot setting unit, and an automatic diameter control unit which controls the grinding amount of the external cylindrical grinding unit responsive to the result of the measurement of the local diameter of the monocrystal ingot.

Abstract: In a bulb slitter, a plurality of first swinging elements are mounted to a frame is juxtaposed relation to each other, and a plurality of second swinging elements are mounted to the frame is juxtaposed relation to each other. The first swinging elements have their respective one ends which are arranged in facing relation to one ends of the respective second swinging elements. The first and second swinging elements are mounted to the frame for angular movement toward and away from each other obliquely vertically. A plurality of first disc-like cutting edges are mounted to the one ends of the respective first swinging elements for angular movement. A plurality of second disc-like cutting edges are mounted to the one ends of the respective second swinging elements for angular movement.

Abstract: An apparatus and method for blow molding large hollow bodies, such as automotive fuel tanks and the like, is disclosed. A fluidized plastic material injection head is located above a given portion of rails. A plurality of mold carriers are disposed on the rails through wheels, each mold carrier carrying thereon mold halves. A clamping device is mounted on each mold carrier to clamp the mold halves together. A hydraulic press device is located near the injection head and presses the mold halves against each other to achieve a tight coupling of them when operated.

Abstract: A method and apparatus for adding minute quantities of radioactive material to frac material, acid material, cement squeezes, or the like, being pumped underground which includes providing a filler material or carrier having a minor portion of radioactive material distributed evenly therethrough, providing a lead shielded container having a variable volume chamber for the filler having the radioactive material and progressively decreasing the chamber volume at a predetermined rate to meter outflow of the filler with radioactive material from the container and into the line carrying the material being pumped underground. The rate of metering is such as to provide the desired concentration of radioactive material relative to the flow rate of material being pumped underground. The filler with the radioactive material is preferrably a solid plug and a grinder is used to progressively grind material at a selected rate from the leading end of the plug into particles of selected size.

Abstract: A composition containing dispersed pigment comprises, as a dispersing agent, a reaction product of at least one polyamine having two or more primary amino groups and/or secondary amino groups and at least one polyisocyanate having two or more isocyanate groups.

Abstract: A tape amount displaying apparatus displays a used amount of a tape or a remaining amount thereof. A signal corresponding to a length (l.sub.t) of an outermost periphery of the tape wound in a reel is outputted from an outermost periphery length signal outputting circuit and then stored in a memory. Each time a one-turn detecting circuit detects one turn of the reel, the predetermined value (2.pi.d) is added to the length of the outermost periphery read out from the memory if a rotational direction detecting circuit detects that the reel rotates in a predetermined direction, or the predetermined value (2.pi.d) is subtracted from the outermost periphery length if the rotational direction detecting circuit detects that the reel rotates in the opposite direction. The result of such an addition or subtraction is again stored in the memory. The content stored in the memory is squared (l.sub.t.sup.2), and then a predetermined value (4.pi..sup.2 r.sub.h.sup.2) is subtracted from the squared value (l.sub.t.sup.
