Publication number: 20130011219Abstract: In an embodiment, a booklet conveying device includes: a pair of conveying units; a positioning unit; a pressing unit; and a conveying-force changing unit. The pair of conveying units convey a booklet made of a stack of folded sheets, and change a distance therebetween. The positioning unit positions the booklet by making a leading-end portion of the booklet abut thereto. The pressing unit presses the booklet positioned by the positioning unit onto one of the conveying units in order to fix. The conveying-force changing unit changes the conveying force exerted by the conveying units.Type: ApplicationFiled: June 25, 2012Publication date: January 10, 2013Applicant: RICOH COMPANY, LIMITEDInventors: Akihiro Musha, Nobuyoshi Suzuki, Kiyoshi Hata, Kei Sasaki, Makoto Hidaka, Takashi Saito, Takamasa Matsumoto, Shingo Matsushita

Publication number: 20120085118Abstract: A refrigerant compressor that enhances compressor efficiency by both reducing an amplitude of pressure pulsations and reducing pressure losses in a discharge muffler space into which is discharged a refrigerant compressed at a compression unit. A low-stage discharge muffler space is formed in the shape of a ring around a drive shaft. In the low-stage discharge muffler space, a discharge port rear guide is provided in the proximity of a discharge port through which is discharged the refrigerant compressed by a low-stage compression unit. The discharge port rear guide is provided at a flow path in one direction out of two flow paths from the discharge port to a communication port in different directions around the drive shaft, and prevents the refrigerant from flowing in that direction, thereby causing the refrigerant to circulate in a forward direction in the ring-shaped discharge muffler space.Type: ApplicationFiled: May 24, 2010Publication date: April 12, 2012Applicant: Mitsubishi Electric CorporationInventors: Tetsuhide Yokoyama, Toshihide Koda, Shin Sekiya, Kei Sasaki, Raito Kawamura, Taro Kato, Atsuyoshi Fukaya, Takeshi Fushiki, Hideaki Maeyama, Masao Tani

A low-stage discharge muffler space is formed in the shape of a ring around a drive shaft. In the low-stage discharge muffler space, a communication port flow guide is provided so as to cover a predetermined area of an opening of a communication port from a side of a flow path in a reverse direction out of two flow paths in different directions around the drive shaft from a discharge port through which is discharged the refrigerant compressed by a low-stage compression unit to the communication port through which the refrigerant flows out. The communication port flow guide transforms a direction of a flow into a direction of a connecting flow path.Type: ApplicationFiled: May 24, 2010Publication date: April 12, 2012Applicant: MITSUBISHI ELECTRIC CORPORATIONInventors: Tetsuhide Yokoyama, Raito Kawamura, Kei Sasaki, Shin Sekiya, Taro Kato, Masao Tani, Atsuyoshi Fukaya, Takeshi Fushiki
