Abstract: A development support system for supporting new product development activities including designing, manufacturing experimental models and testing the functions of the experimental models and for providing an environment for the cooperative activities of a plurality of members of a development project team has a model storage for storing product models, resource models of resources to be used for product development and product development activity models; a target storage for storing target values of schedules of product development, and the cost and the performance of the product; an estimating unit for estimating schedules of product development and the cost and the performance of the product on the basis of the models stored in the model storage; a support unit for support the operations of the members of the development project team for making reference to the models, the target values and the estimated values, and changing and particularizing the models, the target values and the estimated values; a noti

Abstract: A recording material including paper containing cellulose fibers as the main component, with the elongation percentage of the paper in the cross direction thereof when immersed in water at 20.degree. C. for 1 minute being 1.8 % or less, is produced and recycled. In addition, paper containing cellulose fibers, with the same elongation percentage as mentioned above in the machine direction thereof is also provided.

Abstract: A method of recycling an image-bearing recording material, at least part of a surface portion having a paper layer which contains cellulose fibers and bears thereon images formed by a thermofusible or thermosoftening ink, includes the steps of causing the image-bearing surface portion of the recording material to hold a water-containing image removal acceleration liquid thereon, and causing the images to adhere to an image releasing member with the application of heat and/or pressure to the images, whereby peeling the images away from the surface portion, with the surface portion of the recording material having a contact angle (cos.theta.) of -0.6 to 0.8 when a liquid with a surface tension of 40 mN/m is placed dropwise on the surface portion of the recording material.

Abstract: A flat bed knitting machine with at least one carriage mounted to a needle bed. A yarn changing device is capable of picking yarn guide collars from collar support racks located at both ends of the needle bed. Each collar rack is designed to hold a plurality of yarn guide collars. The yarn changing device includes a collar support mechanism carried by the carriage for detachably holding a selected one of the collars. The collar support mechanism has three working positions including an operational position and two transfer positions. Each transfer position allows the transfer of the selected collar between the collar support mechanism and one of the support racks. A mechanism is also provided to change the position of the collar support in response to movements of the carriage relative to the needle bed. In a preferred embodiment, the position changing mechanism changes the position of the collar support mechanism in response to movements of the carriage relative to the needle bed.
