The cartridge includes one of a pressure-loss emphasizing type cartridge and an ion-exchange efficiency emphasizing type cartridge, which are selectively exchanged with each other, for a common case of the ion-exchange filter. The ion-exchange efficiency emphasizing type cartridge is one for an ion-exchange filter having a high pressure loss and high ion-exchange efficiency and, on the other hand, the pressure-loss emphasizing type cartridge is one for an ion-exchange filter having a pressure loss lower than that of the former ion-exchange filter and an ion-exchange efficiency lower than that of the former ion-exchange filter.

A fluid machinery includes a helical mechanism connected to a driving mechanism, which is driven via a crank shaft. The helical mechanism includes a cylinder defining an inner space, a roller disposed inside the cylinder so as to be rotated in an eccentric manner, the roller being formed with a plurality of helical grooves on an outer peripheral surface, and at least one seal ring groove between respective helical grooves, a plurality of helical blades fitted to the helical grooves so as to be disposed between as inner peripheral surface of the cylinder and the outer peripheral surface of the roller, and at least one seal ring fitted to the seal ring groove so as to tightly seal the inner space as a plurality of operation sections. Furthermore, a plurality of suction ports and a plurality of drain ports, associated with respective operation sections, communicate with each other.

An internal combustion engine includes an engine control unit for setting a ratio of fuel injection quantity of both the injectors. The engine control unit includes a memory storing four sheets of ignition timing maps, with reference to which the maximum torque generation timing and knocking limit torque generation timing, at the direct injection injector (100%) and port fuel injection injector (100%), are calculated. The engine control unit further operates to calculate a correction amount from correction amount map, and calculates first interpolation value of the maximum torque generation timing at the above 100% operation time of both the injectors and second interpolation value of the knocking limit torque generation timing at the above 100% operation time of both the injectors. A value in which the correction amount is added to either one of the above first and second interpolation value on a delay angle side is calculated as ignition timing.

An apparatus for correcting deformation of a gas turbine blade includes a stationary die fixed to a backside of a tip shroud of a gas turbine blade to hold a back surface thereof and a pressing die pressing a front surface of the tip shroud so as to press the tip shroud of the blade between the pressing die and the stationary. A hydraulic drive mechanism including pressure generator is arranged for pressing the pressing die against the tip shroud held by the stationary die and a control device is operatively connected to the hydraulic drive mechanism so as to set and indicate a driving condition on a basis of deformation correction data preliminarily stored in the control device.

There is provided an internal combustion engine, in which a fuel pressure is changed and a fuel injection quantity is controlled in accordance with an engine operating condition when fuel is injected. The internal combustion engine comprises a cylinder, a direct injection injector arranged so as to supply the fuel to the cylinder, a detection unit for detecting an operating condition of the internal combustion engine, and a control unit for controlling the fuel injection. The control unit includes two maps describing tow factors of a fuel injection characteristic coefficient and an invalid injection period with respect to the fuel pressure of the direct injection injector, a first calculating section for calculating a required fuel injection quantity necessary for injecting the fuel into the cylinder in accordance with an information from the detection unit, and a second calculating section for calculating a required fuel injection period in accordance with the required fuel injection quantity and the two factors of the fuel injection characteristic coefficient and the invalid injection period with respect to the fuel pressure both of which are obtained from the two maps, a controlling section for controlling the fuel injection such that the fuel is injected for the required fuel injection period (T) through the direct injection injector.

A slide rail unit for guiding an object to be pulled out, such as drawer, from a body, such as furniture or desk, in which the object is slidably accommodated includes a body side rail provided for the body, and an object (i.e., drawer) side rail provided for the object to be pulled out to be slidable relative to the body side rail. The body side rail and the object side rail each has a portion bent in a circular-arc shape so that the object is pulled out along a circular-arc locus.

A material, such as track member for a linear motion guide, having a plurality of rows of portions to be hardened which are thermally influenced on each other, is hardened by emitting laser beams so as to simultaneously irradiate a plurality of rows of portions of the material to be hardened, and moving the laser beams irradiating the rows of portions to be hardened relatively in a longitudinal direction of the portions to be hardened. In this hardening process, the laser beam irradiation is performed such that, in a sectional plane perpendicular to an optical axis of the laser beam, a length of a laser beam irradiation shape in the longitudinal direction of the portion to be hardened is set to be longer than a length thereof in a direction perpendicular to the longitudinal direction.

A hydraulic pressure generating apparatus includes a hydraulic oil feed line for feeding hydraulic oil with high pressure from an oil tank to a hydraulic pressure control system of a generator by an oil feeding pump unit, a hydraulic oil return line for returning drain oil from the hydraulic pressure control system to the oil tank, and a circulation line for circulating and purifying the hydraulic oil of the oil tank by a circulating pump unit. In such apparatus, the hydraulic oil is flame resistant hydraulic oil which is hardly deteriorated by direct heating, and the flame resistant hydraulic oil is heated by a heater disposed in the oil tank.

A contact pin for an IC socket. The contact pin is formed from a metal material having conductivity and includes an elastic portion that is elastically deformable by a force applied thereto. A contact portion is formed at an end portion of the elastic portion and contacts an IC lead of an IC package. The elastic portion is polished to improve durability.

A shut-off valve disposed between openings formed to a vacuum chamber includes a casing, a valve body disposed inside the casing and having a shaft rotating around a central axis of the valve body, a drive unit for driving the valve body to rotate the shaft, and an open/close mechanism provided for the shaft for opening and closing each of the openings. The open/close mechanism includes a sheet member mounted to the shaft so as to protrude outward in a radial direction of the shaft to thereby close each of the openings, an urging member urging the sheet member inward or outward in the radial direction of the shaft, and a seal member connected to the sheet member so as to be associated therewith and forming a sealed space between the sheet member and the shaft, which is formed with an air passage communicating with the sealed space.
