Publication number: 20240110897Abstract: A second polymer is prepared through derivatization of a first polymer. Kendrick Mass Defect (KMD) analysis is applied on a mass spectrum of the second polymer, to thereby produce a plot. Meanwhile, a plurality of mass candidates for a non-primary-chain segment are calculated based on a mass spectrum of the first polymer. The KMD analysis is applied on the plurality of mass candidates, to thereby produce reference images. A mass of the non-primary-chain segment is identified through matching of two KMD analysis results.Type: ApplicationFiled: September 28, 2023Publication date: April 4, 2024Inventors: Takaya Satoh, Masahiro Hashimoto, Haruo Iwabuchi

Patent number: 4905619Abstract: This invention relates to an electronic sewing machine in which sewing data consisting of the needle sewing positions encoded for each stitch of a predetermined stitch pattern is stored. It comprises at least a memory for storing sewing data consisting of the encoded stitch data in group in regard to the stitches the needle sewing positions of which change regularly and the read out time data which instructs the reading out of the encoded stitch data by the number of times equal to the number of stitches encoded in group. This composition is effective not only in reducing the capacity required for storing stitch data but also shortening the time required to process the stitch data.Type: GrantFiled: June 14, 1988Date of Patent: March 6, 1990Assignee: Juki CorporationInventors: Ikuro Iimura, Haruo Iwabuchi, Fumio Wada

Patent number: 4719868Abstract: The present invention relates to an improvement in the home point detection of a motor for a sewing machine wherein the motor is used to rotate a cam into a predetermined feed pitch formed on the cam, and change in the quantity of work piece feeding that corresponds to such feed pitch is transferred to a feed dog through a linkage means. Respective feed pitches are formed in each of the regions of the cam, whereas the detecting position of home point of the motor is set in a suitable position. Moreover, the rotating direction of the cam toward the detecting position of home point is reversed in accordance with each of the regions. Accordingly, the returning speed of the motor back to the detecting position of home point is made fast and only one home point detector is used.Type: GrantFiled: February 25, 1986Date of Patent: January 19, 1988Assignee: Tokyo Juki Industrial Co., Ltd.Inventors: Haruo Iwabuchi, Yutaka Asaba

Patent number: 4619213Abstract: A drive control mechanism and a safety device in a sewing machine in which thread in a predetermined amount necessary for the formation of one seam each time a seam is to be formed. The drive control mechanism comprises a control circuit for allowing current to flow to a machine motor when no thread amount signal is produced though a position signal is produced at the start of the machine. The safety device comprises a thread paying-out detection circuit operable when a position signal is produced, but no thread amount signal is produced, an alarm for producing a sound or light warning in response to the operation of the thread paying-out detection circuit and a motor stop circuit for interrupting flow of current to a machine motor.Type: GrantFiled: September 27, 1984Date of Patent: October 28, 1986Assignee: Tokyo Juki Industrial Co., LtdInventors: Ikurou Iimura, Kuniharu Sakuma, Haruo Iwabuchi
