Publication number: 20160061361Abstract: A pipe-connecting device includes: an inner ring having an outer circumferential portion having, at a tip end, a tip-contracted outer-circumferential flared surface that flares a tube end portion; a pipe joint body that has a tubular screwing portion having an external thread; and a union nut having an internal thread. The inner ring flares the tube end portion, and is inserted into the tubular screwing portion. The tip-contracted outer-circumferential flared surface is clamped and pressed through the tube by the union nut which is screw-advanced by screwing with the tubular screwing portion. A tube pressing portion which is in the union nut, and which presses the tube against the tip-contracted outer-circumferential flared surface is formed into an inclined inner circumferential surface which is inclined in the same direction as the outer-circumferential flared surface with respect to the axis of the tubular screwing portion.Type: ApplicationFiled: March 24, 2014Publication date: March 3, 2016Applicant: NIPPON PILLAR PACKING CO., LTD.Inventors: Makoto Fujii, Toshihide Iida

Publication number: 20150242346Abstract: The variation of the timing of starting interrupt processing in response to a timer interrupt request is reduced regardless of the condition of processing of other interrupts. A semiconductor data processing device incorporated in each of plural electronic control devices coupled to a network for time-triggered communication system is provided with a central processing unit, a communication control circuit and an interrupt control circuit. The communication control circuit has a local time timer for use in time-triggered communication and issues, based on time counting by the local time timer, a timer interrupt request for time-triggered communication. When a timer interrupt request for time-triggered communication is received, the interrupt control circuit performs control to cause the central processing unit to delay, by a predetermined reservation time, starting the interrupt processing to be performed in response to the timer interrupt request.Type: ApplicationFiled: May 11, 2015Publication date: August 27, 2015Inventor: Makoto Fujii

Patent number: 8393438Abstract: The object of the present invention is to provide a sound absorbing material having a light weight and excellent sound absorbing performance, and a sound absorbing material consisting of a fiber sheet made of fibers containing at least 50% by mass of a porous fiber having many minute pores, each minute pore opening onto the surface of the porous fiber, and having an airflow resistance in the range of between 0.05 and 3.0 kPa·s/m. The porous fiber having many minute pores, each one opening onto the surface of the porous fiber, has air-permeability, and so a sound absorbing property in itself, and a sheet made of the porous fiber having air-permeability and sound absorbing property has even further sound absorbing properties created by the spaces between the porous fibers, resulting in the sheet becoming a sound absorbing material with extremely great sound absorbing efficiency.Type: GrantFiled: March 18, 2009Date of Patent: March 12, 2013Assignee: Nagoya Oilchemical Co., Ltd.Inventors: Masanori Ogawa, Makoto Fujii, Naohiro Mizutani
