Title: Recording and reproducing device and transmitter
Inventor: SAEKI HIROAKI
IPC: H04N21/442
Filed: 1999-11-18
Abstract: PROBLEM TO BE SOLVED: To considerably reduce a total time until video recording completion from the time when start of video recording is instructed. SOLUTION: When a recording start of a program repetitively broadcast on a channel 300 is instructed, a current time T2 at that time, a next repetitive top time T1 of a program, a program time length, a recording end time T3 resulting from adding the program time length to the current time T2, are detected, and a program from the current time T2 until the recording end time T3 is recorded. Moreover, the recording positions at the current time T2, the repetitive top time T1 and the recording end time T3 are stored.  In the case of reproduction, various recording positions stored at recording are referenced, the program from the recording position at the repetitive top time T1 until the recording position at the recording end time T3 is reproduced and then the program from the recording position of the current time T2 until the recording position at the repetitive top time T1 is reproduced. Then a wait time at the recording start is made zero and the program can be reproduced from the top of the program in the order of substantial broadcasting.

Title: Film laminate corrugated cardboard and its production
Inventor: IKEDA MAKOTO
IPC: B32B3/28
Filed: 1992-12-09
Abstract: PURPOSE:To prevent damage of a film and to prevent deterioration of moisture permeability by constituting at least one side of liner paper of the liner paper laminated with the film and providing a mold releasing agent layer on the outside surface of the film. CONSTITUTION:Liner paper 4 is formed by successively laminating a film layer and a mold releasing agent layer 3 on a liner 1. An one-sided corrugated cardboard sheet 6 is obtained by pressing and laminating the liner paper 4 and core paper 5 corrugated between the upper-step roll 7 of a single facer and the lower-step roll 8 through the press roller 9 of the single facer. Since the one-sided corrugated card-board sheet 6 is easily peeled from the roll by existence of the mold releasing agent, quantity of heat given from the roller 9 to the film layer 2 is small. Therefore the one-sided corrugated cardboard sheet 6 does not adhere to the roller by fusion of the film. The film of thermoplastic resin such as polyethylene, poly-propylene and polystyrene is shown as the concrete example of the film constituting the liner paper.

Abstract: PURPOSE:To provide a highly sealable and fashionable can body, by forcing the top of a double seam portion at the opening edge of a can into nearly a coextensive or inwardly extensive relationship with the folded edge of the can body by employing a simple plunger. CONSTITUTION:A free roll 13 and a chuck 11 are moved downwardly simultaneously, with the inner peripheral portion of a double seam portion 5, i.e., a chuck wall portion 6, supported by a chuck 11 and while forcing the double seam portion 5 to curl under pressure by the free roll 13, whereby the neck-in portion of a can body is gradually deformed inwardly to force the double seam portion into the interior of the can body until the top 7 of the double seam portion extends inwardly of a fold-back edge 8. Thereafter, the fold-back edge of the can body, with the double seam portion 5 held in a vertical position, is pressed downwardly by a press ring 14 having a concavely curved arc-shaped face, thereby bending the fold-back edge 8 inwardly in such manner as to cover the top of the double seam portion for formation into a final can shape. This method permits the lower part of the double seam portion to be located inwardly of the can body, without being protruded from the lower end of the can body.
