Abstract: In a system when a camera head and a signal processing unit connected to each other, the signal processing unit inputs a synchronizing signal from an external device, and transmits reference signals, such as a clock signal, horizontal and vertical synchronizing signals based on the input synchronizing signal to the camera head. Further, the signal processing unit controls the camera head so as to select a predetermined signal and output it via a predetermined signal line. When the predetermined signal received by the signal processing unit, the signal processing unit detects phase difference between phase of the predetermined signal and one of the reference signals corresponding to the predetermined signal, and shifts the one of the reference signals so that the phase difference reduces. Thereby, the camera head and the signal processing unit are synchronized.

Abstract: A steel pipe having a circular sectional form is retained by a retainer. A rotatable first roller is pressed against an intermediate portion of the steel pipe. In this state, a pusher causes the steel pipe to move axially of the steel pipe. This causes the steel pipe to be plastically deformed while maintaining the first roller in rolling contact with the steel pipe whereby a flat portion is formed at the intermediate portion of the steel pipe. Subsequently, a second roller for forming rack teeth which is formed with teeth at its outer periphery is pressed against the flat portion of the steel pipe while the steel pipe is relatively moved in the axial direction thereof. This causes the flat portion of the steel pipe to be plastically deformed for formation of rack teeth at the flat portion.
