Title: Cold forging method for spline
Inventor: TAKINO TOSHIO
IPC: B21K23/00
Filed: 1978-05-23
Abstract: PURPOSE: To easily form the spline in the circumferential plane of the boss without loading large forming load on the die, by installing the circumferential groove at the position near the end part of the spline to be formed, around the circumferential plane of the boss projecting from the flange part, and by pressing the die in the direction of axis of this boss.  
     CONSTITUTION: The circumferential goove 6 is formed at the position near the end part of the spline 5 to be formed in the circumferential plane of the boss 3. The angle α of the side edge of the groove 6 on the side of the end face 3a of the boss 3 is suitable to be 0W60 degrees against the vertical direction. The spline forming die is pressed in the direction of axis of the boss 3 from the side of the end face 3a, for carrying out the cold forging work to form the spline 5 in the outer circumferential plane of the boss 3, ranging from the end face 3a to the groove 6. In this case, the wall of the outer circumferential plane of the boss 3, being thrusted toward the flange part 2 due to the formation of the spline 5, swells into the groove 6; as a result, the resistance against the load is reduced, so that the die becomes free from the large forming load.

Title: Electrophotographic receptor
Inventor: KAWAMURA TAKAO
IPC: H01L31/08
Filed: 1980-05-08
Abstract: PURPOSE:To provide photosensitivity to an amorphous silicon receptor at both positive and negative polarities and increase the dark volume resistivity by adding oxygen, hydrogen and an impurity selected from the IIIb group of the periodic table to the receptor. CONSTITUTION:Amorphous silicon formed by a glow discharge decomposition method and contg. about 5 10<-2>-10<-5>atomic% oxygen, about 10-40atomic% hydrogen and an about 200-20,000ppm impurity selected from the IIIb group of the periodic table, especially boron is used as a photoconductor layer. When hydrogen is added as a carrier gas for SiH4, it combines with a dangling bond to enable to control the electrical conductivity, yet the dark resistivity is low. By further adding oxygen, the dark resistivity is enhanced remarkably. Since a higher oxygen content deteriorates the photoconductivity, oxygen is added in said range. In the figure, A, B and C show the characteristics of amorphous silicon contg. no oxygen, 10<-5>atomic% oxygen and 10<-2>atomic% oxygen, respectively.
