摘要:
A novel polypeptide binding to SMG-1, a polynucleotide encoding the same, and a system for screening a substance which artificially modifies an mRNA surveillance mechanism, are disclosed. The polypeptide has an activity of binding to SMG-1, an activity of being phosphorylated by SMG-1, and an activity of modifying SMG-1 activities through these activities.

An image recording apparatus includes an image carrying part, a developing part and an image transferring part. The image carrying part has a surface on which an electrostatic latent image is formed. The developing part develops the electrostatic image into a toner image by selectively applying toner to the surface of the image carrying part. The image transferring part transfers the toner image onto a recording sheet or an intermediate image transferring part. Fine particles are uniformly formed on the surface of the image carrying part, and a portion of the fine particles is transferred from the image carrying part with the toner image. The fine particles are smaller in diameter than the toner particles.

A yarn winding method is disclosed where at the step of winding yarn on bobbin, at changing a full bobbin to an empty bobbin, a running yarn is wound on an auxiliary winding roller provided separately from the bobbin, travelling of the yarn and rotation of the auxiliary winding roller are then stopped, a full bobbin is exchanged by an empty bobbin, a part of the yarn wound on the auxiliary winding roller is then taken out to form a thread line for setting the yarn to the empty bobbin, travelling of the yarn, rotation of the auxiliary roller and rotation of the empty bobbin are then started, the yarn-setting thread line is shifted toward the side of the empty bobbin to wind the running yarn onto the empty bobbin, and the normal winding operation on the empty bobbin is then started. Also an apparatus for practicing this yarn winding method is disclosed.

A cleaning device removes a toner attached to an image carrier of an electrophotographic-type image forming apparatus. The cleaning device includes a cleaning blade, a housing and a block member. The cleaning blade is in contact with a surface of the image carrier to removes the toner. The housing stores the toner removed by the cleaning blade. The block member causes the toner to temporarily remain the toner in a vicinity of a distal end of the cleaning blade. The block member is formed of a sheet-shaped elastic member. One side of the block member is fixed to the housing. A repulsive force against bending in an end portion of the block member in a longitudinal direction is substantially smaller than a repulsive force against bending in a center portion of the block member.

In a horizontal grinding-type rice polishing machine which is so configured that a grinding roller (1) installed circularly and fixedly on a horizontal rotation axis (10) is covered with a concentric cylindrical bran removing screen (S) that can be split into longitudinal two screen halves (2) to thereby form a rice polishing room, the total of even number of a stopper (3) and a flap (4) are fixedly provided on an inner peripheral surface of each of two-part split screen halves (2) of the bran removing screen (S) so that they align alternately in the axial direction, the stopper (3) and the flap (4) being formed by a circular arc member which curves along the circumference of a circular cross section perpendicular to the axial center of the cylinder. Between the flap (4) and the outer periphery of the grinding roller (1), a distance that allows passing of rice while restricting passing amount is secured, and a distance between the stopper (3) and the outer periphery of the grinding roller (1) prevents the rice from flowing. The screen halves (2) of the bran removing screen (S) have the same structure, and are so configured that when the respective ends in the axial direction are inverted, the stopper (3) and the flap (4) are inverted, and in the rice polishing machine, at least one screen half (2) can be arranged so that the respective ends in the axial direction are inverted. Also, position of a joint surface (J) between the screen halves (2) is variable in the circumferential direction about the rotation axis (10).

A charger has a cylindrical rotation tube coming in contact with an image receptor on which a toner image is formed, the rotation tube to which a predetermined charge bias is applied, and drive means for driving the rotation tube at a predetermined peripheral speed, the charger for uniformly charging the surface of the image receptor. When the peripheral speed of the image receptor is V1 and the peripheral speed of the rotation tube is V2, the following relation is satisfied: 1.01
