Abstract: A humanized antibody is provided, which is obtained by transplantation of the complementarity determining region of a mouse monoclonal antibody B-B10 specific to a human IL-2 receptor into a human antibody. The antibody has a very low antigenicity, and therefore, it is useful for treatment of carcinoma expressing IL-2 receptor.

Abstract: In a projection type video display device comprising a light writing type spacial light modulator, disturbances brought about by a resetting pulse and appearing in a projected picture as a black belt or beat are prevented. This is accomplished by causing the resetting pulse, which is to withdraw electric charges produced by incoming writing light and accumulated in spacial light modulator, to occur within a vertical blanking period synchronized with vertical synchronization signal.Further, by changing the pulse width and the voltage of the resetting pulse in accordance with vertical synchronization frequency, pictures of a certain fixed brightness are made available against various vertical synchronization frequencies; and even with a high vertical synchronization frequency, projected pictures are never annoyed by such disturbance that is caused by a resetting pulse dislocated out of the vertical blanking period.

Abstract: In a planetary gear set, a pinion shaft extending through one of planetary pinions has one and opposite end portions supported by two spaced plate portions of a carrier. Needle bearings are disposed between the pinion and the pinion shaft. Pinion washers extend around the piston shaft and radially between the pinions and the adjacent plate portions of the carrier. In order to withstand a thrust which the needle bearings are subjected to, the pinion washers have integral portions extending axially into spaces defined between the pinion, the needle bearings and the spaced plate portions of the carrier. Alternatively, the pinion shaft may have integral portions extending radially into the spaces.

Abstract: An assembly in which a touching needle and a connecting portion are arranged coaxially on a frame spaced from each other, each lead of an electric parts unit is connected to the touching needle or the connecting portion. The assembly is inserted into a probe in form of a cylinder through and end thereof, and the touching needle comes out through the other end thereof, when the assembly is fixed in the cylinder.

Abstract: According to this invention a central conductor of a probe is connected to that of a coaxial cable by joining a shell and cylindrical metal fitting. An end of an inner insulator of the coaxial cable enters a larger diameter portion of an elastic cylinder which fits in a fixed position of the cylindrical metal fitting, a central conductor of the coaxial cable stretching further to penetrate a narrower diameter portion adjacent to the larger diameter portion. A pin is pressed into the narrower diameter portion from the other side of the larger diameter portion side. By this operation the central conductor is held tightly between the surfaces of the narrower diameter portion and the pin. When the connection of the probe and cylindrical metal fitting is completed, the pin deforms the elastic cylinder so that the central conductor of the probe contacts tightly with the pin, which enables complete conductivity between the central condutors.

Abstract: An electric parts unit is located between a pair of holders formed inside surface of a jointing portion of a frame of an assembly. When the assembly is inserted into a cylinder, a projection(s), which is on an outer surface of the jointing portion and has relation to the positions of the holders, is (are) pressed by an inner surface of the cylinder so that the jointing portion bends inward and the holders hold the electric parts unit. Therefore, even if the probe is used under a quaking condition, the electric parts unit will not be quaked so that any noise will not be produced.

Abstract: In a two stroke fuel injection type internal combustion engine provided with intake and exhaust valves, a basic amount of fuel to be injected is calculated in accordance with an engine load and engine speed. Values of a factor corresponding to a ratio of air captured by an engine cylinder for combustion to the total amount of air introduced into the engine are stored in a memory in accordance with combinations of an engine load and engine speed. A value of a captured air factor corresponding to a detected combination of an engine load and speed is calculated by a map interpolation. The basic amount is corrected by the captured air factor so that a desired air-fuel ratio is obtained. The captured air factor may be further corrected in accordance with a secondary engine condition, other than an engine load and speed, such as a cooling water temperature, intake air temperature, atmospheric air temperature, atmospheric air pressure, exhaust gas temperature, or intake pressure.

Abstract: A two-cycle internal combustion engine having three, or a multiple of three, cylinders comprises a cylinder head having an intake port and exhaust port opened to a combustion chamber, to which fresh air compressed by a supercharger is introduced via an intake valve. The intake and exhaust valves are operated in response to a crank angle. A one-way valve is provided in the intake port so as to prevent air or gas from flowing back toward the supercharger. The exhaust valve is opened earlier than the intake valve when the speed of the downward movement of the piston is relatively high, so that a part of exhaust gas in the exhaust port flows back to the combustion chamber in the condition. In a heavy load condtion, cross scavenging and air charging effects due to exhaust pulsation can be achieved.

Abstract: A compound of the formula: ##STR1## useful as a fungicidal agent against phytopathogenic fungi, particularly their strains resistant to benzimidazole, thiophanate and/or cyclic imide fungicides.

Abstract: A two-cycle internal combustion engine comprises a cylinder head having two intake ports and an exhaust port opened to a combustion chamber, to which compresses fresh air is introduced via two intake valves. The intake and exhaust valves are operated in response to a crank angle. During an idling or light load running condition, an air control valve closes the second intake port. The exhaust valve is opened earlier than the second intake valve, and the first intake valve is opened later than the second intake valve, while the speed of the downward movement of the piston is relatively high. An exhaust gas swirl rotating around a cylinder axis is formed when the exhaust gas flows back into the condition chamber and the fresh air is slowly introduced via the first intake valve onto the exhaust gas swirl in the idling or light load condition. A large amount of fuel is rapidly introduced into the combustion chamber via the second intake valve in a heavy load condition.
