Title: Heat-sealing method of package opening
Inventor: KANEOKA TSUGIO
IPC: B29C65/08
Filed: 1996-07-11
Abstract: PROBLEM TO BE SOLVED: To securely seal even when foreign materials exist a heat-sealing part, by further applying the ultrasonic sealing on the sealing part after the opening of a plain bag has been heat-sealed. SOLUTION: The opening of a package 1 is closed and heat-sealed after the contents have been charged therein and then, it is sealed by ultrasonic waves applied on the heat-sealing part 2. In the ultrasonic wave sealing 3, it is sealed by pressing, transmittion, retaining of the pressure (cooling), and release. The pressurizing process in this time is carried out in a considerable high pressure but as it is fused with heat-welding, it can withstands the ultrasonic sealing and hence, the sealant layer is not broken. In this way, the heat- sealing resin of the heat-sealing part 2 is again fused to make firm the sealing part and embed foreign materials into the resin and completely seal the opening.

Abstract: PROBLEM TO BE SOLVED: To increase the force of adhesion between a barrier plate material layer and a plasma-display-panel barrier plate forming surface on a substrate to prevent separation of a barrier plate from the barrier plate forming surface during a disposal process, etc., by roughening the barrier plate forming surface to a predetermined depth, and performing subsequent processes thereafter. SOLUTION: In a method for forming the barrier plate of a plasma display panel in which the barrier plate partitioning a discharge space is formed on a substrate, the barrier plate forming surface of the substrate 1 is roughened to a predetermined depth. After a barrier plate material layer 4 is deposited on the barrier plate forming surface roughened, a mask 6 with a masking pattern corresponding to the barrier plate is provided on the barrier plate material layer 4. The bulkhead material layer 4 is partly removed by spraying of abrasives, the barrier plate 7 is formed beneath the mask 6, and the mask 6 is removed thereafter.

Filed: 1989-07-15
Abstract: PURPOSE:To surely absorb impact, following a rapid increase of a load, through a cushion or elastic material by interposing it in a space in which a play in a connection part between input and output side members of a DC motor is formed. CONSTITUTION:Power is transmitted from an input side member (carrier) 15 to an output side member (output shaft) 2 through a cushion or elastic material 3. In this way, impact, following a rapid increase of a load, can be absorbed by impact absorbing force of this cushion or elastic material 3. Further when large torque is necessary for importance of output efficiency, the impact absorbing force in the cushion or elastic material 3 is deteriorated, but here driving is performed only at a low speed by the characteristic of a DC motor, even when a stop is generated by rapidly increasing the load, deterioration of the impact absorbing force generates no problem because of small impact generated.
