Title: Method for preventing carburization of seamless pipe
Inventor: KASUYA TOSHIAKI
IPC: B21B45/04
Filed: 1992-12-21
Abstract: PURPOSE:To prevent the carburization of the inside surface layer of pipe stock under a rolling process by subjecting the inside surface of the pipe stock to mechanical descaling and removing the lubricating material components existing on the inside surface of the pipe stock. CONSTITUTION:The lubricating material components (lubricants, fat and oil components) existing on the inside surface of the pipe stock are removed by the mechanical descaling, such as projecting of silica sand, etc., together with compressed air from a sand injection nozzle 14 prior to heating of the pipe stock 10 in the method for preventing the carburization of a seamless steel pipe having <=0.10% carbon content. The descaling effect is much higher than by immersion washing by polychloroethylene, alkaline liquid, etc., water washing with brushes, etc. The sand remaining on the inside surface of the pipe stock 10 is removed by injecting water from a water injection nozzle 16 after the mechanical descaling. The lubricant components sticking to the remaining sand, etc., are completely discharged and the higher effect of preventing the carburization is assured.

Title: Image-pickup device, video processing device and image-pickup processing system
Inventor: YOKOYAMA TOSHIHIKO
IPC: H04N5/00
Filed: 1997-12-24
Abstract: PROBLEM TO BE SOLVED: To compensate for the phase difference between a CLK and image- pickup signals in an inexpensive constitution, despite the use of an image-pickup means such as CCD(charge-coupled devices) of different pixel numbers by omitting a PLL circuit that causes the phase shift of sampling timing. SOLUTION: An MPU 20 contained in a camera head part 1 makes the control signal compound which shows the phase timing of a reference clock that is set based on the number of image-pickup elements of its own CCD 13 via an adder 16 in its start mode and gives a notification to an extension board part 3 in a state which is compounded with an image-pickup signal. Upon the receipt of the notification from the MPU 20, an MPU 48 included in the part 3 applies an appropriate phase control to the clock signal that is separately received from the part 1 via a phase control circuit 11. A signal processing circuit DSP 9 receives a clock signal that has undergone phase control, applies a prescribed process to the clock signal, and outputs the processed signal to a host PC, etc.
