Title: Program loading system
Inventor: KUGIMIYA SETSUO
IPC: G06F13/00
Filed: 1984-11-27
Abstract: PURPOSE:To perform control to prevent plural hosts from carrying out arbitarily the IPL respectively by providing a function to check the working states of plural channel adaptors. CONSTITUTION:When a channel adaptor 5-1 recognizes a command given from a host 10-1 as an IPL command, the adaptor 5-1 informs the IPL request information to a central processor 2. The processor 2 discriminates the working information sent from channel adaptors 5-1-5-n and informs an IPL enable state to the adaptor 5-1 as long as those channel adaptors are working except the adaptor 5-1. While an IPL-unable state is informed to the adaptor 5-1 in case even just one of adaptors excluding the adaptor 5-1 is working. Thus the adaptor 5-1 informs the rejection of the IPL request to the host 10-1.

Abstract: PURPOSE:To make working for one optical fiber connector alone performable, by pressing a ferrule tip to an abrasive device by a deviation device in accordance with a copying surface device, with which a driven device comes into control, and polishing it. CONSTITUTION:In an initial state, a projecting part 10 is on a copying surface 9A of a taper member 9, while a tip 110 of the ferrule 1 held by a chuck 4 will not come into contact with a grindstone 13, and a shaft center of the chuck 4 and a turning shaft 81 both are tilted at a small angle. When a support member 8 is turned round to the center of the shaft 81 from this state, the projecting member 10 goes down along an inclined plane 9B, the ferrule end face 110 is ground by the grindstone 13, and the ferrule 1 is rotated more than 360 deg. clockwise or counterclockwise by a c.w. and c.c.w. driving part 11, thus is comes to a conical form. Next, when it goes down up to a flat copying surface of the taper member 9, access of the tip 110 to a polishing surface is stopped, and a desired end form is securable owing to a sparkout effect. Thus, only one time scanning is carried out, one optical fiber connector is machinable into the desired dorm in a highly accurate manner.
