Abstract: PURPOSE:To mass produce optical disks at a low cost by providing a main vacuum deposition chamber provided with two main vacuum evacuation devices and preliminary vacuum chambers respectively having intrinsic vacuum evacuation device before and behind said chamber at the time of forming a reflection film consisting of Al, etc., on a disk substrate by a sputtering device and producing the optical disk. CONSTITUTION:The resin substrate 2 made of polycarbonate, etc., is used and the Al film is formed on the surface thereof by sputtering an Al target 23 at the time of producing the optical disk such as compact disk (CD). Since H2 and O2 are much adsorbed on the above- mentioned resin substrate, the substrate 2 is first put into a 1st preliminary vacuum chamber 16 and the inside of the chamber is evacuated by the vacuum evacuation device 17 to get rid of the H2O and O2; thereafter, the substrate is put into the main vacuum deposition chamber 20, where the H2O and O2 are thoroughly removed from the substrate by using either of the main vacuum evacuation devices 21, 22. After the Al target 23 is sputtered to make vapor deposition, the substrate is discharged through the preliminary vacuum chamber 18. The evacuation device 21 of the main vacuum deposition chamber 20 is changed over to the auxiliary main vacuum evacuation device 22 and the operation is continued if said device is damaged by the H2 and O2 to prohibit the execution of the treatment. The mass production is thus executed without lowering the working efficiency.

Filed: 1994-05-27
Abstract: PURPOSE:To eliminate the reception of data except for regular file data and to suppress a wasteful data processing by compulsorily terminating communication when received data quantity exceeds file size information which is previously transmitted from a transmission-side. CONSTITUTION:When file size RFS information is detected to be registered in the facsimile information field FIF of a partial page boundary signal in a reception-side facsimile equipment, RFS is stored in RAM2. Then, CPU 1 compares it with the count value of a file size counter FSC. When the count value of FSC is judged to exceed RFS, CPU in a reception station cuts a line by a network controller 11 and compulsorily terminates communication. Even if unnecessary data except for file data are continuously transmitted, an unnecessary data processing can previously be prevented.

IPC: G02B6/24
Filed: 1986-06-11
Abstract: PURPOSE:To shorten splicing work time by generating arc discharge from a discharge fusing part of opposed optical fibers under inert gas to evapolate and remove an ultraviolet curing resin layer and fusing and splicing the exposed optical fibers under normal aerial discharge. CONSTITUTION:An optical fiber core 2 whose end face is cut out is set up on a discharge fusing part and fixed by a V-groove base and a clamp 3 to position the end face on the center of a pair of discharge electrode rods 8.

In this case, the length of time that barrel collapsing starts is controlled by both the detected brightness and detected film-sensitivity. For example, the length of time that barrel collapsing starts is set in three steps; three minutes, five minutes, and ten minutes, and the lens barrel is collapsed in a shorter time as the above-mentioned parameters become higher in them.
