Patent number: 7525116Abstract: A phototimer detects the dose of an X-ray radiation that has passed through a stimulable phosphor panel, and a stored quantity calculator calculates the quantity of radiation energy stored in the stimulable phosphor panel. An irradiation time ratio setting unit reads an irradiation time ratio from an irradiation time ratio storage unit according to the calculated quantity of radiation energy, and sets the read irradiation time ratio in an erasing unit. Based on the irradiation time ratio, the erasing unit applies erasing light including a radiation in a short wavelength range to the stimulable phosphor panel and thereafter applies erasing light comprising only a radiation in a long wavelength range to the stimulable phosphor panel, thereby erasing a residual radiation image from the stimulable phosphor panel.Type: GrantFiled: August 21, 2006Date of Patent: April 28, 2009Assignee: FUJIFILM CorporationInventor: Kiyotaka Suzuki

Patent number: 7504650Abstract: A stored quantity calculator calculates the quantity of radiation energy stored in each of divided areas of a stimulable phosphor panel. Erasing energy set to a level depending on the calculated quantity of radiation energy stored in each of the areas is applied from an erasing unit to the stimulable phosphor panel. Therefore, a residual radiation image remaining in the stimulable phosphor panel is efficiently erased with a required minimum level of erasing energy.Type: GrantFiled: July 28, 2006Date of Patent: March 17, 2009Assignee: FUJIFILM CorporationInventor: Kiyotaka Suzuki

Publication number: 20060056300Abstract: A bandwidth control apparatus in an IP network such as the Internet eliminates a packet discard for each user, and equally assigns bandwidths to the user. A bandwidth measuring portion measures a total bandwidth of a single or a plurality of TCP sessions for each user, and a window size changing portion reduces a window size of a TCP session ACK packet of a user whose total bandwidth value exceeds a maximum bandwidth preset. Alternatively, an ACK time changing portion delays a TCP session ACK packet of a user whose total bandwidth exceeds the maximum bandwidth value preset.Type: ApplicationFiled: November 8, 2005Publication date: March 16, 2006Inventors: Yoshio Tamura, Yasuo Tezuka, Akio Yaba, Masanori Hashimoto, Kiyotaka Suzuki

Patent number: 6194344Abstract: A process for the preparation of a high-softening-point pitch rich in mesopores having a softening point measured by temperature gradient method of 150° C. or higher, a weight loss by heating up to 300° C. of 5 wt. % or less and mesopores of 100 mm3/g or greater, in terms of minute pore volume calculated by the Dollimore-Heal method, and a process for making carbonaceous materials carrying metal thereon are disclosed. The high-softening-point pitch rich in mesopores can easily provide carbonaceous material carrying metal thereon by using no oxidizing agent such as nitric acid, and, therefore, the high-softening-point pitch rich in mesopores is especially suitable for the production of carbonaceous materials carrying metal thereon or highly crystalline graphitized carbonaceous materials in a short heating time.Type: GrantFiled: October 7, 1999Date of Patent: February 27, 2001Assignee: Maruzen Petrochemical Co., LTDInventors: Masatoshi Tsuchitani, Ryoichi Nakajima, Kiyotaka Suzuki, Hitoshi Shigematsu, Katsutoshi Nishitani

Patent number: 4925547Abstract: A process for co-production of a pitch for the manufacture of HP carbon fibers and a pitch for the manufacture of GP carbon fibers is proposed. The pitch for the manufacture of GP carbon fibers is prepared from the spent fraction not used in the production of an optically anisotropic pitch suitable for the manufacture of HP carbon fibers. The spent fraction has hitherto been discarded as a valueless material. According to the present process, a pitch for the manufacture of so-called ultra HP carbon fibers with tensile strength of over 400 Kg/mm.sup.2 and modulus of elasticity of over 60 ton/mm.sup.2 and a pitch for the manufacture of GP carbon fibers can be produced simultaneously. Both pitches have very excellent spinnability and when they are spun, they cause no fiber cut-off even at a high spinning rate of, for example, 500 m/min or 700 m/min.Type: GrantFiled: August 21, 1989Date of Patent: May 15, 1990Assignee: Maruzen Petrochemical Co., Ltd.Inventors: Masatoshi Tsuchitani, Sakae Naito, Hiroshi Morijiri, Kiyotaka Suzuki
