A method for operating an internal combustion engine having a fuel system which feeds fuel at a given pressure to a metering valve provides that a controller defines the opening time and the closing time of the metering valve and correspondingly actuates the metering valve so that the metering valve opens and closes at the defined times. In order to permit precise metering of fuel even in high-speed internal combustion engines there is provision for the controller to define at least one of the times for the opening or closing of the metering valve while taking into account the counterpressure actually prevailing at the outlet opening of the metering valve.

A vehicle stability control device for reducing and / or canceling a yaw moment owing to the imbalance in longitudinal forces between the left and right wheels of the vehicle by automatically steering wheels. The control device estimates a longitudinal force difference-caused yaw moment and a vertical load shift-caused yaw moment exerted on the vehicle body. A steering apparatus is operated to apply on the vehicle body a counter yaw moment obtained by eliminating a contribution of the vertical load shift-caused yaw moment from a counter yaw moment calculated from the longitudinal force difference-caused yaw moment.

A two-stroke engine has a cylinder having a cylinder bore with a combustion chamber and an outlet connected with the combustion chamber. A piston is disposed in the cylinder and delimits the combustion chamber. The piston has a piston recess. A crankcase is provided that has a crankshaft rotatably supported therein. The piston drives in rotation the crankshaft. In at least one position of the piston, the crankcase is connected by a transfer passage with the combustion chamber. An air passage is provided as well as a mixture passage that has a mixture inlet that is disposed at the cylinder bore and opens into the cylinder bore and is piston-controlled. The transfer passage is connected by the piston recess to the air passage when the piston is at top dead center. The piston recess has a connection to the mixture inlet in at least one position of the piston.

There is provided a solenoid-type valve actuator for an internal combustion engine, having an inexpensive and single construction which is capable of maintaining stability of operation of a valve and reducing sliding resistance to the valve at the same time, thereby achieving improved response of the valve and reduced power consumption of electromagnets. The solenoid-type valve actuator electromagnetically opens and closes a valve. Two electromagnets are arranged in a manner opposed to each other with a space therebetween. An armature is arranged between the two electromagnets, for reciprocating motion by energization and deenergization of the two electromagnets. Two shafts project from respective opposite sides of the armature and extend through the two electromagnets, respectively, one of the shafts being connected to the valve. Two shaft guides are arranged in at least one of the two electromagnets in a line along the direction of the reciprocating motion of the armature, for guiding a reciprocating motion of at least one of the two shafts performed according to the reciprocating motion of the armature.

In an optical scanner 100, a vibration portion 101 includes first and third elements 3021 and 3023 that vibrate a light guide path 102 in a direction substantially perpendicular to an optical axis direction, and second and fourth elements 3022 and 3024 that vibrate the light guide path in a direction substantially perpendicular to a vibration direction thereof. A driving signal is applied to each of electrodes 3011 to 3014, each of which corresponds to one electrode of each of the first to fourth elements, and the other electrode 3015 is used as a common electrode having a floating potential. A driving signal generator 1007 generates a driving signal such that a median value of driving signals Vy1and Vy2 applied to the first and third elements and a median value of driving signals Vx1 and Vx2 applied to the second and fourth elements correspond to substantially the same value.

A spectra shaping apparatus for chirped pulse amplification(CPA) comprises a CTSI spectral decomposition system and a CTSI spectral synthesizing system being symmetrical, and a spectral modulating system composed of a diaphragm (10) and a plane spectra modulating reflector (5), wherein the CTSI spectral decomposition system totally expands a laser chirped pulse to a spectra plane, the spectral modulating system performs a spectra modulation on the image plane, and the CTSI spectral synthesizing system reverts the modulated spectra into the chirped pulse without distortion, thereby realizing spectra shaping. The apparatus has the feature of manufacturing easy, compacting structure, requiring less space, and cheap in cost etc., which can be different types of configuration for different circumstance application, and which can be utilized in a general laser spectrum shaping and spectrum modulation, especially for a high energy and ultra-high peak-power laser system with a large caliber and a broadband of pulse.

The magnetic tape in which the followings are satisfied, after the magnetic layer is pressed at a pressure of 70 atm. A full width at half maximum of a spacing distribution measured by optical interferometry regarding a surface of the magnetic layer before performing a vacuum heating with respect to the magnetic tape is greater than 0 nm and equal to or smaller than 15.0 nm; a full width at half maximum of a spacing distribution measured after performing the vacuum heating is greater than 0 nm and equal to or smaller than 15.0 nm; and a difference (Safter−Sbefore) between a spacing Safter measured by optical interferometry regarding the surface of the magnetic layer after performing the vacuum heating with respect to the magnetic tape and a spacing Sbefore measured before performing the vacuum heating is greater than 0 nm and equal to or smaller than 12.0 nm.

A guide rail rope deflection inhibition mechanism and method for a parallel soft cable suspension system in ultradeep vertical shaft construction. The guide rail rope deflection inhibition mechanism comprises a T-shaped installation support base, a rotating frame, a hydraulic support rod, and a chuck. The T-shaped installation support base comprises a vertical support rod and a horizontal support rod. The hydraulic support rod comprises an upper hydraulic support rod and a lower hydraulic support rod. The rotating frame comprises an upper Y-shaped frame and a lower Y-shaped frame. The chuck comprises an upper chuck and a lower chuck. The guide rail rope deflection inhibition method treats two guide rail rope deflection inhibition mechanisms as one group, and arranges at least two groups along the vertical direction on the shaft wall. While guaranteeing the smooth sliding of a direction guiding frame, the freedom of the guide rail rope part is restrained by the chuck, thereby enhancing the stability and safety of hoisting containers.

An airbag device for a vehicle tire capable of stabilizing the vehicle timely when the tire is exploding or being punctured suddenly to avoid potential accidents and to ensure driving comfort. The airbag device comprises a resilient outer ring installed between the tire and the wheel hub, and an inner ring serving to support the resilient outer ring. The resilient outer ring and the inner ring are compressed between the tire and the wheel hub under normal tire air pressure, and a space serving to increase driving comfortability and keep the outer ring from contacting the inner surface of the tire tread is designed between the resilient outer ring and the inner surface of the tire tread. When the tire is exploding or the air pressure of the tire is lost, the resilient outer ring is capable of bouncing instantly to support the weight of the vehicle.
