Patent number: 11932028Abstract: A printing device includes a housing, a print head, a platen roller, a holder, and a cover. The housing has a cassette attaching opening through which a printing cassette accommodating a printing tape is attachable to the housing. The holder holds one of the print head and the platen roller. The holder is movable between a nip position in which the print head and the platen roller nip the printing tape and a non-nip position in which the print head and the platen roller do not nip the printing tape. The cover is attachable to the housing. The cover is movable between a covering position to cover at least part of the cassette attaching opening and an engaged position to engage with the housing. The holder moves from the non-nip position to the nip position in conjunction with movement of the cover from the covering position to the engaged position.Type: GrantFiled: April 21, 2022Date of Patent: March 19, 2024Assignee: BROTHER KOGYO KABUSHIKI KAISHAInventors: Yuya Tagami, Shinji Ukai

Patent number: 9664412Abstract: Provided is a heating device which makes it possible to effectively perform heat exchange between a heating element and a heat medium without increasing the number of components, and further to eliminate air retention and increase of a pressure loss. A heating device 1 is constituted of a case 2 including therein a flow path 3 through which a heat medium flows, and an electric heating wire heater 4 disposed in the flow path of the case to heat the heat medium. The case comprises a first case section 6 and a second case section 7 each of which has at least one opened surface and which are connected to each other in a state where respective openings are made to abut on each other, and a plate-like gasket 8 which is interposed between abutment portions of the first case section and the second case section, and seals a space between both the case sections, and the gasket controls the flow of the heat medium in the flow path.Type: GrantFiled: July 2, 2013Date of Patent: May 30, 2017Assignee: Sanden Holdings CorporationInventors: Yusuke Sakai, Hiroyuki Yokoyama, Shinji Tagami

Patent number: 9228573Abstract: A wabble plate type variable displacement compressor has a wabble plate rotation preventing mechanism including an inner ring axially movable relative to a main shaft, an outer ring connected to the wobble plate, a plurality of balls placed between guide grooves of the inner and outer rings and performing power transmission, and a sleeve axially movably engaged with the inner ring, provided so as to be axially movable together with the inner ring. A shape differs between the axial cross-sectional profiles of substantially concave spherical surfaces formed respectively in the inner periphery of the outer ring and the outer periphery of the sleeve such that the closer to the axial opposite ends of the contact portion between both the surfaces the position is, the greater the clearance between these surfaces. Implementation of the wabble plate rotation preventing mechanism in such a compressor can provide excellent durability and silent performance.Type: GrantFiled: October 8, 2013Date of Patent: January 5, 2016Assignee: Sanden Holdings CorporationInventor: Shinji Tagami

Patent number: 9046089Abstract: Disclosed is a wobble plate type variable displacement compressor that uses a constant velocity universal joint mechanism, which comprises an inner ring and an outer ring, balls that are held between guide grooves of the inner ring and the outer ring to transmit power, wherein a wobble plate is connected and fixed to the outer ring. In the compressor, the connecting structure for the outer ring and the wobble plate is formed by providing a plurality of concave portions arranged in a circumferential direction on one member, by plastically deforming the other member partially at locations corresponding to the concave portions such that it fits into the concave portions, and by fixing both members to each other in the axial direction and in the rotational direction by means of the plastic deformation.Type: GrantFiled: May 13, 2009Date of Patent: June 2, 2015Assignee: SANDEN CORPORATIONInventor: Shinji Tagami

Publication number: 20130086932Abstract: In a vehicle air-conditioning device, refrigerant leakage is diagnosed precisely without any restrictions from an operating condition of the air-conditioning device. When the operating condition of the vehicle air-conditioning device is stable, a threshold value Th for determination of refrigerant leakage is set based on an outlet pressure Pd and an inlet pressure Ps of a compressor. Furthermore, a volume flow Gr in that refrigerant pipe running from a condenser to an expansion valve through which the refrigerant circulates in a liquid state is detected. When it is determined that the volume flow Gr exceeds the threshold value Th for determination of refrigerant leakage, a diagnosis result (alarm) indicating that the refrigerant leaks is output.Type: ApplicationFiled: May 27, 2011Publication date: April 11, 2013Applicant: Sanden CorporationInventors: Tetsuya Ishizeki, Atsuo Inoue, Masato Tsuboi, Kenichi Suzuki, Shinji Tagami
