IPC: G11B27/00
Filed: 1986-07-15
Abstract: PURPOSE:To register a great number of files in plural sets of disk devices by distributing them, at time of registering, by deciding the number of the disk device to be registered, according information which represents the attribute of the file, at the time of registering the file in one of the plural sets of disk devices.

Title: Receiver
Inventor: SAKAMOTO TSUTOMU
IPC: H04N7/167
Filed: 1994-07-20
Abstract: PURPOSE:To reduce the number of parts and to simplify structure by employing such constitution that no changeover switch to release a scrambling signal is required when AV equipment is set. CONSTITUTION:When a user applies the power source of a channel selector, a control part 7 judges whether or not the input of the scrambling signal exists in broadcast information inputted to a tuner main body 2 by a detection signal A. In such a case, when no scrambling signal is inputted, the movable contact 6c of an internal selector 6 is left as being connected to a first switch contact point 6a side, and information is outputted by connecting the main body 2 to an output terminal 1e. While, when the scrambling signal is inputted, the contact 6c is switched to a second switch contact point 6b side, and the information is outputted by connecting the main body 2 to the terminal 1e via a decoder 4. In this way, since broadcast to a TV 5 side is performed by releasing the scrambling signal when the decode 4 is connected, the broadcast provided with the scrambling signal such as a pay broadcast can be viewed without receiving disturbance.

Abstract: PURPOSE:To facilitate the collating operation of a film with a print. CONSTITUTION:Firstly, the time T1 required for printing a preceding film is calculated before starting printing. Next, safe time T2 which is until a succeeding film reaches a printing device is calculated.

IPC: B21B3/02
Filed: 1984-08-15
Abstract: PURPOSE:To manufacture a thin stainless steel sheet excellent in surface properties by using specific large and small diameter rolls for the purpose of changing a rolling reduction in cold rolling a stainless steel sheet. CONSTITUTION:In manufacturing a thin sheet material by cold rolling a stainless steel sheet, the cold rolling of a >=50% of the total rolling reduction is first performed by using a large-diameter roll having a <=0.5mum average roughness (Ra) at the center line and a >=150mm.phi diam. Successively, the cold rolling of a >=10% of the total rolling reduction at boundary lubricating conditions, is performed by using a small diam. roll having a <=0.2mum average roughness (Ra) at the centerline and a <=100mm.phi diam. Thus, a thin stainless steel sheet, having surface properties equal to or more excellent than those of a sheet rolled by a convertional Sendzimir rolling mill, can be manufactured even the coil-surface planing process of a stainless steel sheet before cold rolling is eliminated.
