Patent EP-0262883-A1 (EP)
Inventor: ASAYAMA YOSHIAKI
IPC: F02D11/10
Filed: 1987-09-25
Abstract: A throttling apparatus for an automotive vehicle is disclosed which has two independently-rotated throttle valves (2, 4). A first throttle valve (2) is rotatably supported in an air intake passageway (1) of the vehicle and has a cylindrical through hole (3) formed therein. The first throttle valve (2) can be continuously rotated between an open position, in which the through hole is unobstructed and air can flow through the first throttle valve, and a closed position, in which the through hole (3) is obstructed by the walls of the air intake passageway and air can not flow through the air intake passageway. The second throttle valve (4) is a butterfly valve which is rotatably disposed in the through hole (3) in the first throttle. A controller (20) and actuators (10,11) rotate the two throttle valves independently with respect to one another. A controller (2) computes the optimal relative rotational angle (X) of the two throttle valves (2, 4) based on the operating state of the engine, the running condition of the vehicle, and the amount by which the accelerator pedal is depressed. The controller (20) controls the actuators (10, 11) so as to rotate the throttle valves (2, 4) until the actual relative rotational angle equals the optimal relative rotational angle.

Abstract: This invention relates to a single-turn induction heating coil (10) used for floating-zone melting process. According to this invention, both ends of a single-turn coil are crossed over each other in the peripheral direction of the coil so as to form an overlap section, and a pair of power supply portions (19,29) are arranged on an outer peripheral wall so as to allow this RF current to flow through the coil, thereby forming a uniform magnetic field of the coil, and realizing magnetic concentration on an object. As a result, the floating-zone melting process can be stabilized to increase the productivity. Further, striation, microscopic resistance variations and other quality defects of semiconductor crystals caused by the heating coil can be prevented.

Abstract: The invention relates to a method for producing building walls (10) made of concrete or the like and a shuttering system. A sliding shuttering and a corresponding method have proved inflexible in many respects, shuttering construction and fastening also having to be carried out to some extent under great time pressure. The invention provides a solution for this by combining the advantages of a sliding scaffold in the construction of high buildings with the advantages of a climbing shuttering. This is achieved by attaching a plurality of adjoining shuttering panels (21, 22, 23) over a certain height substantially in the vertical and, if appropriate, in the horizontal direction. These shuttering panels are temporarily held stationary. To raise the building wall, the shuttering panel or the lowest shuttering panels is/are moved upwards. <IMAGE>

Abstract: A long wavelength UV ray absorber and a cosmetic comprising the same is disclosed. The long wavelength UV ray absorber comprises (a) a dibenzoylmethane derivative of the type in which the benzene ring of the dibenzoylmethane has a carboxylic acid group, a carboxylate group, or a carboxylic acid ester group, and (b) a polyvalent metal oxide. The long wavelength UV ray absorber can effectively shut out UV-A which is harmful to the skin, thus protecting it from the UV-A. It is stable against light and heat over a long period of time. Since it is sparingly soluble into water, organic solvents, oily substances, or sabum, it is hardly absorbed through the skin and hardly removed from the skin by water or sweat.

The predetermined fraction determines a lesser charge time sufficient to ensure adequate (not full) flash energy for the next flash firing. Thus, the charging time perceived by the photographer always appears shortened to the lesser time, even though the flash device is not fired until it is fully charged. Moreover, the waiting time to fire the flash device can be shortened by relying on the lesser time.
