Patent number: 10667550Abstract: The filter for cigarette product includes a mouthpiece end side-filter material and a front stage-filter material. The mouthpiece end side-filter material has a low air flow-resistance unit that is arranged in a part of a cross section from a front end surface to a rear end surface and having a relatively low air flow-resistance, and a high air flow-resistance unit that is arranged in the remainder of the cross section from the front end surface to the rear end surface and having a higher air flow-resistance than the low air flow-resistance unit. At least on the rear end surface of the mouthpiece end side-filter material, the low air flow-resistance unit is arranged only in one semicircular area, of two parts into which the cross section of the mouthpiece end side-filter material is divided.Type: GrantFiled: September 12, 2017Date of Patent: June 2, 2020Assignee: JAPAN TOBACCO INC.Inventors: Kenji Ito, Yu Ninomiya, Tomiharu Nagata, Hiroyuki Torai, Sadao Ogi, Kazumasa Arae

Patent number: 9427929Abstract: A filter manufacturing machine includes a forming device for forming filter tow into a hollow rod-shaped continuous filter body, a forming tube included in the forming device and having a tubular forming path through which the filter tow is passed while being brought together, a mandrel arranged in the forming tube and forming the tubular forming path in cooperation with the forming tube, and a heat treating section included in the forming tube and configured to heat the filter tow while the filter tow passes through the tubular forming path. The mandrel has a small-diameter portion located at the inlet of the forming tube, a large-diameter portion located at the outlet of the forming tube, and a diameter expansion portion located between the small- and large-diameter portions. The diameter expansion portion is located downstream of the heat treating section as viewed in the moving direction of the filter tow.Type: GrantFiled: September 27, 2013Date of Patent: August 30, 2016Assignee: JAPAN TOBACCO INC.Inventors: Hiroyuki Torai, Satoshi Nakamura

Publication number: 20020141535Abstract: An apparatus comprises a block element 10 formed of an X-ray blocking member and located in a transportation path for an object of inspection, the block element having a through hole 11 through which the object of inspection passes and a slit 12 opening across the through hole, an X-ray tube 20 located close to and opposite one open end of the slit and capable of generating X-rays toward the through hole, and an X-ray detector 30 located in the other open end of the slit and capable of detecting the X-rays transmitted through the slit. The X-rays that are sharply constricted as they pass through the slit of the block element cross the object of inspection that passes through the through hole. Based on the resulting volume of X-ray transmission, the internal conditions of the object of inspection can be subjected to a non-destructive inspection with ease and high accuracy.Type: ApplicationFiled: May 30, 2002Publication date: October 3, 2002Inventors: Hiroyuki Torai, Shigemitsu Inomata, Isamu Takahashi
