A method is described for checking the correct functioning of a serial data transmission in a bus system having at least two bus users. The bus users are connected to the bus via a bus connection unit and exchange messages via the bus. The sending access to the bus for each message is granted to a bus user via the arbitration process according to CAN standard ISO 11898-1, this bus user becoming the sender for this message. The messages have a logic structure according to the CAN standard, i.e., are composed of a start of frame bit, arbitration field, control field, data field, CRC field, acknowledge field, and end of frame field. The correct functioning of the data transmission is checked during the transmission by comparing a transmission signal, sent to the bus connection unit, to the reception signal (CAN_RX) received by the bus connection unit. The method is characterized in that a transmission signal (CAN_TX_DEL), which is delayed by a delay time (T_DELAY) compared to the transmission signal (CAN_TX), is held in the sender, and the undelayed transmission signal (CAN_TX) or the delayed transmission signal (CAN_TX_DEL) is used for checking the correct functioning of the data transmission, as a function of a switchover.

The present invention relates to a casting method which employs rapid solidification of metal, rare-earth metal or the like, as well as to a casting apparatus and a cast alloy. A centrifugal casting method includes the steps of pouring a molten material onto a rotary body; sprinkling the molten material by the effect of rotation of the rotary body; and causing the sprinkled molten material to be deposited and to solidify on the inner surface of a rotating cylindrical mold. The axis of rotation of the rotary body and the axis of rotation of the cylindrical mold are caused not to run parallel to each other. The centrifugal casting method can attain a decrease in average deposition rate. As a result, generation of the dendritic alphaFe phase or generation of a segregation phase of Mn or the like is suppressed, thereby realizing a high-performance R-T-B-type rare-earth magnet alloy.

A screw having stabilized strength, combination with a driver bit that best fits the screw, and a header punch for producing the screw. The screw having stabilized strength has letter Y-shaped bit-fitting grooves formed in the head portion of the screw. Forming the grooves makes fitting of a corresponding driver to the screw easy, prevents occurrence of a cam-out phenomenon to enhance work efficiency, makes torque transmission to be made smoothly and sufficiently, and stabilizes strength. The bit-fitting grooves are formed in a letter Y shape that is substantially equally divided into three sections in the circumferential direction, the grooves being formed at positions required distances away from the central portion of the screw head. The width of each of the grooves extending in radial directions from the central portion of the bit-fitting grooves is set so that the grooves are gradually expanded and substantially equally spaced with spacing each equal to the width of a boundary section between adjacent grooves. Further, the outer peripheral end wall surface of each bit-fitting groove is made substantially vertical from an opening edge section up to a required depth. The outer peripheral end wall surface is displaced downward from a lower edge section of the wall surface toward the central portion of the screw head, and the center where the wall surfaces meet are formed as a substantially conical bottom surface.
