Abstract: PURPOSE:To absorb more effectively pressure load to roller members and prevent the burning and breakage of the roller members in the case of a bearing which has a plurality of roller members rolling on the tracks of inner and outer rings, by providing on the inner surface at the axial center portion of each roller member a penetration hole having recessed and projecting parts. CONSTITUTION:A roller bearing 4 possesses an inner ring 5, an outer ring 6 and a number of hollow cylindrical roller members 7. A number of roller members 7 are housed in the state of their being arranged in a single line at a groove portion 8 formed in the peripheral direction of the inner ring 5. A screw groove 9 having recessed and projecting parts is formed on the inner surface of each hollow cylindrical roller member 7.

Title: Internal combustion engine controller
Inventor: NAKAGAWA HIRONARI
IPC: F02D45/00
Filed: 1992-04-21
Abstract: PURPOSE:To obtain an internal combustion engine controller which does not load a CPU with any burden except a simple hardware and software, and wherein the precision control is performed by means of a number of pulse more than conventional one. CONSTITUTION:In an internal combustion engine controller 1, a pulse is divided by a dividing circuit 5 acting as a dividing means, and the divided pulse is input to a CPU 3. A first PTM 9 as a partial function of a count means takes the pulse not yet divided as the input and counts the pulse on the basis of the count value sent from the CPU 3. Since the CPU 3 takes the divided pulse as the input, the processing load caused by the interruption is not so large. Also, the pulse not yet divided is counted by the first PTM 9 acting as a partial function of the count means, and this count value is sent from the CPU 3, thereby the renewal of the count number is performed in the timing of the divided pulse, so that and the precision control can be easily realized.
