Patent number: 6003828Abstract: To prevent tilting or bending of a large mask frame holder and at the same time to prevent distortion when the mask holding frame is attached to a support base by ball plungers in three of the four corner areas of a mask holding frame that engage V groove bodies which face the ball plungers on the surface of the base, compression springs are provided in those three corners which pre-stress the mask holding frame toward the support base while a compression spring is provided between the remaining corner area of the mask holding frame and the base which acts in a direction pressing the mask holding frame away from the support base, thereby preventing the mask holding frame from bending or tilting. As an alternative, in each of the three pre-stressed corner areas of the mask holding frame, instead of a compression spring, an elastic attachment component in the form of a bracket with spring-like legs mounted to the supporting component can be provided.Type: GrantFiled: May 28, 1998Date of Patent: December 21, 1999Assignee: Ushiodenki Kabushiki KaishaInventors: Takashi Kawahashi, Hiromi Kai

Patent number: 5998740Abstract: A batching of currently supplied articles with non-uniform weights into portions of a uniform target weight is effected by passing the articles through a weighing station (6, 8) to a distribution system (12), in which the articles (4) are selectively allocated to a plurality of receiver bins (14). It is known to improve the capacity of such a system by way of probability calculations based on the normal distribution of the articles in the supply flow, but it is better to base such calculations on a regularly updated recorded histogram (28) of the weight distribution of a relatively high number of newly weighed articles. Thereby the target calculations will rely on factual rather than just expected conditions, and a result is that it is possible to effect batching even when the article weights in the supply flow are not normally distributed.Type: GrantFiled: March 17, 1997Date of Patent: December 7, 1999Assignee: Scanvaegt A/SInventors: Thorkild Kvisgaard, John Bomholt
