Next the temperature is reduced at the rate of about 1.4°C/min to form the N epitaxial layer 6 on the substrate 3, and it is further reduced down to 880°C less than the inversion point once. The temperature is raised at the rate of about 1.4°C/min and is kept on the order of 895°C more than the inversion point again. After this,  when the temperature is reduced at the rate of about 0.3°C/min and is reached  down to 860°C less than the inversion point, the p epitaxial layer 7 is grown on the  layer 6, the pn junction 8 is obtained. In this way, the flatness of pn junction can  greatly be improved.

IPC: F16D27/115
Filed: 1997-01-27
Abstract: PROBLEM TO BE SOLVED: To improve the durability of an electromagnetic coil without necessitating conducting a large amount of current by realizing a predetermined driving force transmission condition by a mechanical means independently from an electromagnetic means and holding or reducing an amount of electric power supplied to the electromagnetic means as it is or reducing it. SOLUTION: When pressing force applied from an electromagnetic pilot clutch mechanism 10d through a first cam mechanism 10e is small, a second cam mechanism 10f is in a non-operation condition. Pressing force generated in the first cam mechanism 10e increases, friction engaging force of a mechanical main clutch mechanism 10c increases, and transmission torque increases gradually due to an increase of friction engaging force of the pilot clutch mechanism 10d. When friction engaging force of the pilot clutch mechanism 10d reaches a predetermined value, the second cam mechanism 10f is operated to press a retainer 13 to a main clutch mechanism 10c side so that they are friction-engaged further firmly and are connected. Consequently, it is unnecessary to conduct a large amount of current to an electromagnetic coil 14d and improve the durability influenced by the generation of heat.
