Method and apparatus for the manufacture of cigarette filters containing particulate material. Filter material composed of cellulose acetate tow is fed in the axial direction through a gap defined between a first pair of rolls so that the transverse cross-section of the filter material is changed to a substantially oval shape. The filter material is then fed through another gap defined between a second pair of rolls so that the transverse cross-section of the filter material is further changed to a substantially heart shape and at the same time providing pockets at axially spaced positions. Particulate material is deposited in said pockets. The filter material is closed so that the deposited particulate material is positioned in the interior of the filter material and wrapped with wrapping sheets.

Polymerization of ethylene or .alpha.-olefins using a catalyst comprising a titanium component obtained by copulverizing the starting titanium component of Ziegler catalysts and organoaluminum compound with a small amount of ethylene or .alpha.-olefins, and an organoaluminum component. The titanium catalyst component can be modified by subjecting the copulverized titanium component to a contact with an inert organic solvent or its mixture with a modifier (1) an oxygen-, sulphur-, phosphor-, nitrogen- or silicon- containing organic compound, (2) a combination of such an organic compound and an aluminum halide, (3) an organoaluminum compound or (4) a Lewis acid.

Dithionites are produced by reacting hydroquinones with bisulfites, pyrosulfites, alkyl sulfites, or aryl sulfites, substances capable of forming these salts upon reacting with sulfur dioxide or sulfurous acid, and sulfur dioxide or sulfurous acid.
摘要:
Polymerization of ethylene or .alpha.-olefins is carried out with use of a catalyst comprising a modified titanium component obtained by pulverizing the starting titanium component of Ziegler solid catalysts and subjecting the resultant to a modification treatment through contact with an inert organic solvent or a mixture thereof with a modifier, and an organoaluminum component.The pulverized product of the starting titanium component is pulverized together with an organoaluminum compound and a small amount of ethylene or .alpha.-olefins thereby controlling the particle size distribution.

An encoding apparatus includes a dividing unit that divides an input signal bit sequence into data blocks and an encoding unit that applies error correction encoding to the data blocks to generate code blocks decodable by repetitive decoding calculations for estimating the reliability of signal bits for a plurality of times and a generation unit that generates redundant bits by performing bit calculations between data blocks of each set combining the divided data blocks; and an output unit that outputs the generated code blocks and redundant bits.
摘要:
The present invention provides oral compositions which contain interferon α (IFNα) as an active ingredient for preventing and/or treating periodontal disease. The number of causative microorganisms of periodontal disease can be suppressed by administering the compositions into the oral cavity. IFNα of the present invention can produce a sufficient effect even when administered at a very low dose. Furthermore, the compositions of the present invention can also be readily administered to animals such as dogs by formulating them into feed or such.
摘要:
An ECU controls the operation of an EPS actuator in order to periodically apply instantaneous motor torque to a steering system when assist continuation control is executed using a sensor signal (residual sensor signal) that is output by a sensor element in which an abnormality has not been detected, regardless of the application of an assist force. The ECU also detects an abnormality in the residual sensor signal based on whether the application of instantaneous motor torque is reflected in the residual sensor signal, which is the basis of the assist continuation control.
