It is an object to provide a continuously variable valve timing adjusting device to improve valve timing advance response for an internal combustion engine. The device, capable of continuously and variably controlling the intake valve timing phase, includes: an advance chamber which hydraulically rotates a vane rotor and a camshaft on the advance side relative to the timing rotor; a retard chamber for rotating the camshaft on the retard side relative to the timing rotor; an advance-retard oil pressure control valve; an oil communicating passage for fluid communication between the advance chamber and the retard chamber; a hydraulic piston, flow control valve which controls the oil in the communicating passage according to the retard chamber pressure when the engine is running at a low speed and a high oil temperature; and a ball valve check valve which checks the oil flow from the advance chamber to the retard chamber.

In a power supply system connected to a load, a plurality of DC power source units are connected in parallel. Each DC power source unit is provided with a unit rated current value Iu, and outputs a unit current in accordance with a target value. A required load capacity provider provides a capacity value Is required in the load. An operating condition detector detects the number m of DC power supply unit which is in an operating condition among the DC power source units. A target value calculator calculates a value obtained by dividing the value Is with the value m, and provides the calculated value Is/m to the respective operating DC power supply unit as the target value.

Either of intake and exhaust valves of an internal combustion engine is provided with a variable valve timing device. In a low-speed, low-load range, exhaust valve advanced-closing control is performed to close the exhaust valve at an earlier timing than the top dead center on the intake stroke, thereby trapping residual combustion gases in the cylinder. Furthermore, the cylinder temperature is raised by setting the intake valve opening timing at around the top dead center on the intake stroke or at a later timing thereof to thereby compress by the piston the residual gases in the cylinder during a period from closing the exhaust valve till the top dead center on the intake stroke. Thus it becomes possible to take in the air-fuel mixture into the cylinder at a higher cylinder temperature than the gas temperature of internal EGR caused by conventional valve overlap.

An ink tank has a housing detachably mountable on a liquid jet recording apparatus, which is capable of retaining liquid directly in the interior thereof, a supply portion for supplying liquid retained in the housing to the recording apparatus and a communication portion with the air outside for communicating the interior of the housing with the air outside. For this ink tank, the supply portion and the communication portion with the air outside are integrally formed, and at the same time, a plate member is provided to make the interior of the housing a closed space by joining the plate member to the housing, and then, erroneous installation prevention portions are arranged for the plate member to prevent the installation on the position other than specifically designated for the liquid jet recording apparatus. With the structure thus arranged, the ink tank makes it possible to easily enhance the dimensional precision of the coupling portion with the recording apparatus, and the erroneous installation prevention portions as well. Thus, without depending on the precision of an ink tank as a whole, it is possible to enhance the reliability of the installation on or coupling with the recording apparatus.

An ink refilling container includes an ink containing portion for containing ink to refill, an ink injection tube for connection with the ink containing portion, an air vent, provided in the ink container, for communication with ambience, and an openable member for closing the air vent. A meniscus of ink is formed adjacent an end of the injection tube, and the ink is not leaked externally when the air vent is closed.

A cam has a profile variable from a high lift curve to a low lift curve in an axial direction. A driving mechanism shifts a cam shaft in the axial direction. A phase adjusting mechanism adjusts the rotational phase of the cam shaft relative to a driving shaft of the internal combustion engine. Angle detecting teeth are shift detecting teeth are alternately arranged on a same cylindrical surface of the cam shaft. Each shift detecting tooth incline at a predetermined angle with respect to an axis of the cam shaft so as to provide angularly advanced and retarded portions in a rotational direction of the cam shaft. A pickup generates sensing signals responsive to the angle detecting teeth and the shift detecting teeth. The sensor faces the angularly advanced portion of the shift detecting tooth when the low lift curve of the cam is selected and faces the angularly retarded portion of the shift detecting tooth when the high lift curve of the cam is selected.

An automatic control system for a multiple ratio transmission includes an electronically controlled variable orifice configuration within a discharge circuit for a downshift control system from a high speed ratio to an intermediate speed ratio. The variable orifice configuration divides the discharge circuit into an upstream part communicating with an accumulator chamber of an accumulator and an intermediate brake release pressure chamber defined by a double acting piston of an intermediate ratio brake servo, and a downstream part communicating with a high speed ratio clutch. A calibrated flow control orifice is disposed in the discharge circuit to control discharge flow of oil from said downstream part. A transmission controller reduces the variable orifice configuration to provide a reduced orifice size during inertia phase of the downshift.
