Publication number: 20010041367Abstract: An analysis method using a dry chemical analysis element accurately measures change in optical density indicating the composition of a liquid sample without requiring accurate control of the amount and position of the liquid sample dripped on the dry chemical analysis element. A one-dimensional or two-dimensional optical reading apparatus measures one-dimensional or two-dimensional distribution of degree of color reaction for a reacted portion of the dry chemical analysis element. Concurrently, the one-dimensional or two-dimensional optical reading apparatus measures a length or a spread area of the reacted portion. Physical density or activity of a target component contained in the liquid sample is determined based on an integrated value of the degree of the color reaction and the measured length or the spread area of the reacted portion.Type: ApplicationFiled: May 14, 2001Publication date: November 15, 2001Applicant: FUJI PHOTO FILM CO., LTD.Inventors: Fumio Sugaya, Yoichi Endo, Nobuaki Tokiwa, Akihiro Komatsu, Yoshihiro Seto

Publication number: 20010022928Abstract: An unwrapping apparatus unwraps a slide pack wrapped with a wrapping sheet to obtain a slide contained therein. As paired rollers forward the slide pack, a squeezing member squeezes the slide backward within an unsealed space in the slide pack to form a wide cut allowance at the front edge of the slide pack. After the slide reaches the rear end of the unsealed space, nip pressure applied to the slide pack by the paired rollers is reduced to further forward the slide pack to a predetermined position. At the predetermined position, a cutter partially cuts the cut allowance to form a slit thereon. Then, the slide pack is transferred back by the paired rollers under a raised nip pressure which is sufficient to squeeze the slide out from the slit. Accordingly, the slide will be gradually separated from the wrapping sheet.Type: ApplicationFiled: March 19, 2001Publication date: September 20, 2001Inventors: Fumio Sugaya, Yoichi Endo, Akihiro Komatsu, Tomoyuki Takiue

Publication number: 20010022311Abstract: A slide pack container housing a plurality of piled slide packs has a cut-off portion. The cut-off portion has a width slightly larger than the width of a slide contained in each slide pack. As a sucker of a package take-out apparatus draws one of the slide packs from the slide pack container through the cut-off portion, a sealed portion of the slide pack interfering with the edge of the cut-off portion is folded inward so that the slide pack is successfully taken out. The sucker transfers the slide pack to a separated unwrapping apparatus. The sucker releases the slide pack when the front edge of the slide pack is caught between paired rollers of the unwrapping apparatus. After a cutter makes a slit on the slide pack, the paired rollers transfer only a wrapping sheet to separate the wrapping sheet from the slide wrapped therewith.Type: ApplicationFiled: March 19, 2001Publication date: September 20, 2001Inventors: Fumio Sugay, Yoichi Endo, Akihiro Komatsu, Tomoyuki Takiue

Patent number: 6241947Abstract: A chemical analysis system for analyzing a sample liquid spotted on a chemical analysis element includes a blood filtering unit, a spotting mechanism which spots the filtrate of the blood filtering unit onto the chemical analysis element as the sample liquid, and an analyzer which analyzes the filtrate on the chemical analysis element. The blood filtering unit includes a filter which filters whole blood to obtain filtrate, a holder which holds the filter and has a blood inlet and a filtrate outlet, a suction system which is removably connected to the filtrate outlet side of the holder and applies a negative pressure to the holder from the filtrate outlet side, and a filtrate receiving container disposed on the filtrate outlet side of the holder to receive the filtrate.Type: GrantFiled: January 26, 1999Date of Patent: June 5, 2001Assignee: Fuji Photo Film Co., Ltd.Inventors: Akihiro Komatsu, Kenji Arai

Patent number: 6170589Abstract: A snowmobile including side grips attached to the right and the left side surfaces of a body of a snowmobile at a position corresponding to a position at a distance towards the front of the snowmobile from the center of gravity of the body. The side grips project from the right and the left side surfaces to define a maximum width (Wmax) of the body. A rear grip is attached to the rear end of a floor member at a distance toward the rear of the snowmobile from the center of gravity. When the snowmobile is inclined, the side grips first come into contact with packed snow (the ground) and serve as a bumper so that a body cover of the snowmobile is not damaged. When carrying the snowmobile, the snowmobile is supported at the right and the left side grip and the rear grip on a snowmobile carrier. A front portion of the body includes an engine compartment in front of the floor which is covered with a body cover. A maintenance opening which is covered with a lid is formed in the back wall of the body cover.Type: GrantFiled: February 14, 1997Date of Patent: January 9, 2001Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Shizuo Kawano, Tadaaki Nagata, Akihiro Komatsu

Patent number: 5879944Abstract: A method of continuously spotting a liquid onto a predetermined number of members to be spotted with the liquid includes the steps of mounting a disposable spotting tip on a suction nozzle, sucking the liquid in the spotting tip in a predetermined amount larger than the predetermined number times the amount for one spotting and discharging the liquid onto the members in sequence by the amount for one spotting by introducing a predetermined discharge pressure into the spotting tip. A signal related to the vapor pressure in atmosphere is obtained and the discharge pressure is corrected according to the change in the vapor pressure inside the spotting tip after the liquid is sucked in the spotting tip so that the same amount of the liquid is discharged onto all the members.Type: GrantFiled: June 26, 1998Date of Patent: March 9, 1999Assignee: Fuji Photo Film Co., Ltd.Inventor: Akihiro Komatsu

Patent number: 5660793Abstract: A biochemical analysis system includes a depositing mechanism which deposits a sample liquid on a chemical analysis slide having a reagent layer, an incubator which incubates the chemical analysis slide with the sample liquid at a predetermined temperature for a predetermined time, a transfer mechanism which loads the slide in the incubator and removes it therefrom, and an optical density measuring system which measures the optical density of the chemical analysis slide after incubation and determines the concentration of a specific biochemical component in the sample liquid through the optical density of the chemical analysis slide. The incubator has a rotary body in which a slide discarding hole is formed at the center thereof and a plurality of slide holding portions are formed to extend from the outer peripheral surface of the rotary body toward the center of the rotary body and communicate with the slide discarding hole.Type: GrantFiled: June 2, 1995Date of Patent: August 26, 1997Assignee: Fuji Photo Film Co., Ltd.Inventors: Shunichi Seto, Akihiro Komatsu

Patent number: 5607861Abstract: A predetermined amount of a liquid sample is accommodated in a sample spotting tip, which is fitted to a bottom end of a suction nozzle for sucking the liquid sample. Thereafter, the sample spotting tip is moved down, and the bottom end of the sample spotting tip is thereby brought into contact with a dry-type frameless chemical analysis film piece. The sample spotting tip is then moved up. The pressure inside the sample spotting tip is increased, while the sample spotting tip is thus being moved up. The liquid sample is thereby discharged from the sample spotting tip onto the dry-type frameless chemical analysis film piece.Type: GrantFiled: June 17, 1996Date of Patent: March 4, 1997Assignee: Fuji Photo Film Co., Ltd.Inventors: Akihiro Komatsu, Nobuaki Tokiwa, Yoshio Saito
