Substantially no Zn11Mg2 phase is present in the metallic structure of the plating layer.

Abstract: A variable dot ink-jet printer having an ejection flow passage with a decrease in sectional area from an ejection port toward the interior of the flow passage and up to a boundary. A draw-in part draws an ink front position in the interior of the flow passage. A push-out part pushes out the ink front position outside the flow passage. When ejecting a small ink drop, the ink front position is drawn at a place having an increase in sectional area by the draw-in part. The ink is pushed outward by the push-out part at such a speed as to exit from an edge of an area of the boundary on the ejection port side.

Abstract: A miniature pump includes a miniature pump portion including a suction passage through which a liquid flows in, and a discharge passage through which the liquid flows out, and a bubble trap portion for blocking an entry of air bubbles into the miniature pump portion. Since the bubble trap portion prevents the entry of air bubbles into the miniature pump portion, a deterioration of pump characteristics owing to the entry of air bubbles can be suppressed, making it possible to obtain a miniature pump that achieves both a large discharge flow rate and stable discharge flow rate characteristics.

Abstract: A liquid injection device has a liquid pressurizing chamber having one or a plurality of apertures, a liquid injection port provided at a part of the liquid pressurizing chamber, a liquid pressurizing member arranged adjacent to the liquid pressurizing chamber, a liquid passage arranged adjacent to the liquid pressurizing chamber; wherein within the aperture(s), a peripheral edge portion of the aperture(s) located at a position opposite to the liquid pressurizing member and the liquid pressurizing member are arranged to be apart from each other at a gap with a predetermined size; further wherein liquid is injected through the liquid injection port by driving the liquid pressurizing member to thereby pressurize the liquid supplied from the liquid passage into the liquid pressurizing chamber.

Abstract: A continous mixing apparatus has an upper rotary disk and a lower rotary disk able to rotate independently of one another. A plurality of scrapers are attached to the upper and lower sides of the upper and lower rotary disks. Scrapers on the lower side of the lower rotary disk have a notch enabling the scrapers to pass over a lower ring plate in the mixer. Material to be mixed is supplied to an upper portion of the mixer, and the product is discharged from a lower portion of the mixer. The device is constructed to enable any subsequently replenished liquids to not rise to the top of the mixing apparatus. The device produces a mixture that is uniform, highly stable, and that has a small particle size or a low viscosity which can be manufactured quickly.

Abstract: A hot-dip Zn—Al—Mg plated steel sheet good in corrosion resistance and surface appearance that is a hot-dip Zn-base plated steel sheet obtained by forming on a surface of a steel sheet a hot-dip Zn—Al—Mg plating layer composed of Al: 4.0-10 wt. %, Mg: 1.0-4.0 wt. % and the balance of Zn and unavoidable impurities, the plating layer having a metallic structure including a primary crystal Al phase or a primary crystal Al phase and a Zn single phase in a matrix of Al/Zn/Zn2Mg ternary eutectic structure. To obtain a plating layer possessing this metallic structure, the cooling rate of the plating layer adhering to a steel strip extracted from a plating bath and the plating bath temperature are appropriately controlled in a continuous hot-dip plating machine and/or appropriate amounts of Ti and B are added to the bath.

Abstract: An energy trapping piezoelectric device trapping a thickness vibration into projections which suppress a reflection of a vibration from end portions of electrodes provided substantially on a piezoelectric plate, and which suppress unnecessary spurious vibrations, low impedance and higher frequency, and a method of easily producing such a piezoelectric device are provided. The piezoelectric device has an energy trapping projection provided over a piezoelectric plate, and a top electrode is divided into a exciting electrode and dummy electrode. A small gap is provided between the divided electrodes, and the electrodes are electrically insulated from each other. The thickness vibration is not generally reflected, and vibrating energies due to the thickness vibrations are substantially trapped into the projections provided on the piezoelectric plate.

Abstract: An interceptor apparatus actuated by seismic and other vibrations comprising a substantially vertically movable rod, a weight capable of engagement with the rod and a plurality of pivotable support arms supporting the weight within a housing and held in a mechanically balanced state in entirety. When the apparatus undergoes seismic or other vibrations, the mechanical balance is lost, whereupon the weight is released from the support arms and is allowed to fall together with the vertically movable rod due to the gravitational forces, thereby effecting the switching of a related fluid circuit or electric circuit.
