Abstract: The combustion chamber is designed for compression ignition internal combustion engines especially for motor cars. The combustion chamber solves the problem of distribution and whirling of fuel mixture in the combustion chamber of the engine and from this the resulting easier ignition of fuel mixture, an optimum insrease in the combustion pressures with optimum layout of the valve gear and the suction and exhaust channels in a simplified design of the cylinder head enabled by the larger eccentricity of the injection jet. The intention is to provide engines with silent operation, low fuel sonsumptions and a low harmful share in the exhaust gases. The principle of the invention is the rotary combust­ion chamber formed in the piston head (1) the bottom of which is formed by a rotary peripheral surface (4) and rotary in­ternal surface (3) on whose border a circular barrier (15) is formed with relations between the depth (9) of the rotary peri­pheral surface (4) in the bottom of the piston (1) and the depth of the top (10) on the barrier (15), the largest diameter (7) of the rotary internal surface (3) and the largest diameter (8) of the rotary peripheral surface (4), and the depth (10, 13) of both rotary surfaces (3, 4) of the piston bottom.

Abstract: A motor-driven power steering apparatus comprising a steering assisting motor, a torque sensor detecting steering torque, a vehicle speed sensor, and a steering angular velocity detecting unit detecting steering angular velocity of steering mechanism. The power steering apparatus sets the value of current to be delivered to the steering assisting motor in correspondence with the detected steering torque and vehicle speed. The power steering apparatus sets the current value to be 0 when the steering torque remains in the dead zone in which the steering torque value is less than the first predetermined value. If the steering torque is more than the first predetermined value and less than the second predetermined value, the current value is set to increase as the steering torque value increases. If the steering torque is in excess of the second predetermined value, the growth rate of the current value against the steering torque is set to diminish as the vehicle speed rises. Further, the apparatus sets the subtraction current of which value increases as the detected steering angular velocity and the vehicle speed increase, and then subtracts the subtraction current from the set current value, transmitting the subtracted result to the motor. Since the value of the subtraction current grows when the vehicle runs   fast and a small value of current is set, only a small amount of current flows through the motor.

Abstract: The transcutaneous implantation catheter has between the intracorporeal first section (10) and the extracorporeal third section (12) a second section (11) which consists over its entire length of an open-pore fibre web, which is also porous on the outer surface. For the purpose of a rapid incorporation which does not cause inflammation and for the purpose of a good transition from the subcutaneous connective tissue to the area of the skin epithelium, it is of particular advantage if the porosity (the spacing of the fibrils of the web) increases from the inside to the outside. In this way the second section (11) can adhere to the tissue. The implantation tunnel is completely closed, and for this reason no fluid can form outside the catheter. The risk of infection is reduced. The first section (10) consists of the same material as the second section (11), but has smooth surfaces and a wall of solid material.
