  • Patent number: 8246597
    Abstract: A pant-type wearing article configured so as to prevent a lateral zone of a front waist region and an associated lateral zone of a rear waist region which should remain fastened together from being needlessly disengaged from each other. In the pant-type wearing article an outer surface of a base sheet strip constituting a front fastener component is bonded to a fixed region defined on an inner surface of a front lateral zone. The front lateral zone includes a free region to which the base sheet strip is not bonded. The free region normally takes a posture folded back in a waistline direction so that an outer surface of the front lateral zone lies inside.

  • Patent number: 8045874
    Abstract: An image forming apparatus includes a control device that calculates a developing ability of the developing device based on a detection value detected by an optical detection device from the plural toner patches. The control device adjusts an image formation condition based on the calculated developing ability. A factor detection device is provided to detect a contributing factor that causes the developing ability to largely change after the last adjustment of the image formation condition. The control device controls image formation such that when the factor detection device does not detect the contribution factor and a developing ability calculated this time is different from that calculated last time (as to a part of the plural toner patches), the plural toner patches are formed based on a prescribed fixed image formation condition so that an attraction amount of toner attracting to the plural toner patches enter a prescribed range detectable for the optical detection device.
