Abstract:
A method of deriving a path of contact of a face gear with a pinion gear includes positioning the pinion gear, shifting the pinion gear from either towards or away from the face gear along a rotational axis, deriving a first relationship between a rotational angle of the pinion gear and a fluctuation error angle, deriving second and third relationship by shifting the first relationship in either way for 360 degree divided by the number of the gear teeth, deriving a first point which the first and second relationships share and a second point which the first and third relationships share, deriving a third point, at which the fluctuation error is the same as the first and second points, between the first and second points, and determining a curve line on tooth flanks of the gear teeth on the basis of the first, second, and third points.

Abstract:
An information processing apparatus comprises a plurality of control units, a shared memory, a processing number table and a start-up time table. When a transaction is received, each of the control units determines whether the current time in the shared memory coincides with the most recent start-up time in the processing number. If the current time does not coincide with the most recent start-up time, each of the control units updates the most recent start-up time with current time and if or not, adds 1 to the number of transactions being processed in the processing number table so as to update the number of transactions being processed. After the number of transactions is updated, each of the control units sums up the number of transactions being processed in the processing number table. Each of the control units determines whether the number of transactions is not more than the threshold value in the shared memory. If the number of transactions is not more than the threshold value, each of the control units starts the distributed transaction to be processed.
