Abstract: A wafer processing method includes preparing a holding table having a blade clearance portion formed therein so as to correspond to a notch of a wafer, holding the wafer by the holding table so as to make the notch of the wafer correspond to the blade clearance portion of the holding table, reducing the diameter of the wafer by cutting the wafer by a cutting blade along an outer peripheral edge of the wafer in a state in which an end of the cutting blade is positioned below the holding surface of the holding table and therefore removing at least a part of the notch portion, and forming a second notch in the wafer by cutting the wafer in a thickness direction by the cutting blade along the blade clearance portion of the holding table.

Abstract: The present invention is concerned with a roll-baler of a construction, in which the rotational movement of its rear chamber of the bale chamber for its opening and closing is done smoothly, while its lock mechanism is designed to be simple, so that the bale-shaping material of a short length may be fed into the bale chamber 4 through its inlet port “a”. In this type of the roll-baler, the bale chamber 4 is mounted on the machine body 1 at its position, where the inlet port “a” of the bale chamber 4 is open frontward, and the terminal end part 3a of the transporting conveyor 3 is so made as to its conveying surface forming an inclined surface “c” which is downwardly slanted, the inclined surface “c” being disposed at a position to constitute a part of the peripheral wall of the bale chamber 4, in opposition to the lower half side of the peripheral surface of the roll bale R to be formed within the bale chamber at the place where the inlet port “a” of the bale chamber 4 is present.

Abstract: A roll baler equipped with a hopper 2, and a transporting conveyor 3 for carrying bale shaping material discharged from beneath a discharge port 20 defined in the bottom face of the hopper 2 into a material receiving port 40 of the bale-shaping chamber, wherein the transporting conveyor 3 is divided into two parts of: a hopper-side transporting conveyor 3a provided in a space extending from beneath the discharge port 20 to the front position beneath the delivery mechanism 5; and a bale-shaping-chamber side transporting conveyor 3b provided in the space extending from beneath the delivery mechanism 5 to the receiving port 40 of the shaping chamber 4, both these hopper-side transporting conveyor 3a and bale-shaping-chamber-side transporting conveyor 3b being each driven independently one from the other.

Abstract: Spandex-type polyurethanes are protected against mechanical diagradation and yellowing which is produced by nitrogen oxide, chlorine or UV light, by incorporation of poly (N,N-diethyl-2-aminoethyl methacrylate) and either zinc oxide or an admixture of huntite and hydromagnesite.

Abstract: An artificial tooth root comprises a substantially cylindrical root part to be imbedded in a jaw bone, and a substantially cylindrical crown part to be projected out of a jaw bone and to be provided with a dental prosthesis. The root part is constituted by a base member provided with a multiplicity of convexities or concavities having a substantially identical configuration and being arranged with even intervals on the same axes apart from the central axis of the root part and with even intervals on the same circumferences. The convexities or concavities on a circumference and the ones on the neighboring circumference are alternately arranged, and the boundaries between the convexities or concavities and the base member are formed by smoothly curved surfaces.

Abstract: An electrically operated power steering device connected to a steering system of a motor vehicle to provide supplementary steering power by means of an electric motor. A motor control unit for the electrically operated power steering device controls the rotational direction and output torque of the electric motor by the sum of an assistance signal based on the signal from a torsional torque sensor and a velocity sensor in the steering system, a restoration signal based on the output signal from a steering angle sensor, and an auxiliary assistance signal based on the output signal from the torsional torque sensor in the steering system as a command signal.

Abstract: A system having a motor operatively connected to a steering system for reducing the steering effort is provided with a torsion torque sensor for detecting torsion torque in the steering system during a steering operation, and a steering angle sensor provided for detecting steering angle. In response to the output signal of the torsion torque sensor, an assist signal is produced, and in response to the output of the steering angle sensor, a return signal is produced and a reducing signal dependent on the speed of steering of a steering wheel is produced. The reducing signal is added to the assist signal thereby reducing the assist signal, so that the output torque of the motor is decreased. When the steering wheel is stopped in a steered position the output torque of the motor is produced in the return direction of the steering wheel.
