Abstract: A titania-doped quartz glass suited as an EUV lithographic member is prepared by feeding a silicon-providing reactant gas and a titanium-providing reactant gas through a burner along with hydrogen and oxygen, subjecting the reactant gases to oxidation or flame hydrolysis to form synthetic silica-titania fine particles, depositing the particles on a rotating target, and concurrently melting and vitrifying the deposited particles to grow an ingot of titania-doped quartz glass. The target is retracted such that the growth front of the ingot may be spaced a distance of at least 250 mm from the burner tip.

Abstract: Pellet damaging is prevented at the time of pellet charging into a storage tank. There is provided a method of storing a gas hydrate in which pellets obtained by compression molding of powdery gas hydrate are conveyed into a storage tank by the use of a slurry liquor, which method includes pouring a liquid for impact absorption in advance into the storage tank so that the impact on the pellets charged in the storage tank is absorbed by the liquid for impact absorption.

Abstract: This invention concerns a turbo-charged engine with EGR comprising an EGR passage connecting an exhaust passage upstream of a turbine of a turbocharger and an intake passage downstream of a compressor to each other for returning some of exhaust gas in the exhaust passage to the intake passage, and an EGR valve provided in the EGR passage for adjusting a passage area of the EGR passage. Capacity of the turbine is set such that in a high speed and high load region of the engine operating state, if the exhaust gas is supplied to the turbine with the EGR valve closed, the turbocharger overruns beyond a maximum speed limit, and if the EGR valve is opened to return some of the exhaust gas to the intake passage, the turbocharger rotates at less speed than the maximum speed limit. EGR can be performed in the high speed and high load region of the engine operating state without reducing power output and worsening fuel consumption.

Abstract: A turbo charger system (32) for a diesel engine (1) with a simple structure, but improved in output, torque and fuel consumption rate. A high-stage turbine (3) and low-stage turbine (4) are provided in series on an exhaust gas line (2) of the engine (1). A high-stage compressor (6), which is connected to the high-stage turbine (3), and a low-stage compressor (7), which is connected to the low-stage turbine (4), are provided in series on an intake air line (5) of the engine (1). A bypass line (20) with a valve (21) is provided over the high-stage turbine (3). The bypass valve (21) is completely or substantially completely closed until the engine (1) reaches its maximum torque point (14) so as to raise a supercharging pressure. From the maximum torque point (14) to the maximum output point (15), the bypass valve (21) is gradually opened to adjust the supercharging pressure. The bypass valve is completely or substantially completely opened at the maximum output point (15) to suppress the supercharging pressure.

Abstract: A combustion chamber defined by a recess formed in the top of a piston in the direction of the central axis thereof with its geometry being progressively enlarged in the direction of the recess. The intensities of swirl flow and squish flow are optimized by letting the two flows interact with each other in the upstream side so as to optimize the air flow in the combustion chamber overall. In the meantime, fuel is atomized and injected through a fuel injection nozzle means, which has five or more nozzle holes, toward the side wall of the combustion chamber so as to circumferentially divide the chamber by the fuel sprays into five or more approximately equal sections. Thus, uniform dispersion and distribution of fuel, together with the optimized flow of air, is achieved in the combustion chamber, whereby the air utilization rate is raised and the combustion unburnt particulate matters are decreased.

Abstract: According to the present ivention, a combustion chamber of internal combustion engines comprises: a main combustion chamber which is created by recessing the piston top; a swirl chamber which is contiguous to said main combustion chamber via a passage; and a fuel injection nozzle to supply atomized fuel into said main combustion chamber and swirl chamber. Because of the above arrangement, a relatively quick combustion takes place in the swirl chamber and a relatively sluggish combustion takes place in the main combustion chamber. As a result, the generation of HC, NOx, or smokes are suppressed while improving an output, a fuel consumption rate, and a thermal efficiency.
