Publication number: 20170367044Abstract: A base station according to the present embodiment receives, if the radio terminal is in a connected mode, via a bearer between the base station and a serving gateway, downlink data addressed to the radio terminal, from the serving gateway, and includes a controller configured to transmit the downlink data to the radio terminal. The controller does not release but maintains the bearer, if the extended DRX operation is configured to the radio terminal, when the radio terminal transitions to the idle mode. The controller receives, even if the radio terminal is in the idle mode, from the serving gateway, the downlink data addressed to the radio terminal, via the bearer, and buffers the downlink data until the downlink data is transmitted to the radio terminal.Type: ApplicationFiled: August 30, 2017Publication date: December 21, 2017Applicant: Kyocera CorporationInventors: Masato Fujishiro, Shingo Katagiri, Hiroyuki Adachi, Kugo Morita

Patent number: 5898550Abstract: A magnetic tape cassette comprises an approximately rectangular bottom wall provided with an opening, into which a spindle is to be inserted, a side wall extending along the periphery of the bottom wall, and a structural part formed integrally with the bottom wall at a corner of the bottom wall and in proximity to the side wall. The magnetic tape cassette is of a thin-walled type, constituted of a resin, and integrally molded by feeding the resin from a position corresponding to the vicinity of a center point of the bottom wall into a mold. The bottom wall is provided with a flow path-like, thick-walled portion extending along a direction heading from the position in the bottom wall corresponding to the position, from which the resin is fed into the mold, approximately towards the structural part.Type: GrantFiled: November 25, 1997Date of Patent: April 27, 1999Assignee: Fuji Photo Film Co., Ltd.Inventors: Shingo Katagiri, Shoji Suzuki, Yukiyoshi Ishii

Patent number: 5785176Abstract: A cassette accommodating case in which a tape cassette can be inserted in either a forward or backward orientation, and for preventing slackening of a magnetic tape, and to secure the tape cassette to eliminate play. Positioning projections having inclined surfaces are provided on each side of a casing section. When the casing section and a cover section are closed, the inclined surfaces abut against the ends of side projections on side surfaces of the tape cassette to push the tape cassette when the casing and cover sections are closed. A rotation-preventing projection of an accommodating case protrudes into a common area of the hubs when a cassette is loaded in the forward and backward orientations, and the projection includes two plate-like portions of different heights, disposed in parallel, and with a predetermined interval therebetween. A distal end of the long plate-like portion has a guiding inclined surface for correcting the positional offset of the hub by contacting its inner peripheral surface.Type: GrantFiled: October 15, 1996Date of Patent: July 28, 1998Assignee: Fuji Photo Film Co., Ltd.Inventors: Shingo Katagiri, Teruo Ashikawa

Patent number: 5782355Abstract: A cassette case which allows positioning and fixing of a hub without biting of a hub pawl, and enhances the convenience with which the case is used. A plate-like portion comes at its edge into contact with a corner of a peak of a hub pawl without the plate-like portions of the projection coming at their edges into engagement with the hub pawl when a cover section of a storage case has been closed relative to a casing section. The sum of pushing forces exerted on the hub pawl by the plate-like portion causes the hub to rotate to thereby introduce the hub pawl into a space formed between the plate-like portions. In order to carry out the above-mentioned operation, the plate-like portion is designed to have an edge extending in a direction from a front to a rear, and vice versa, of a magnetic tape cassette to be encased in the storage case, and the plate-like portion is designed to have an edge making a predetermined angle with the above-mentioned direction.Type: GrantFiled: November 12, 1997Date of Patent: July 21, 1998Assignee: Fuji Photo Film Co., Ltd.Inventors: Shingo Katagiri, Teruo Ashikawa

Patent number: 5662854Abstract: A magnetic tape cassette accommodating case has a cover member having a pocket for receiving one end portion of a magnetic tape cassette and a casing member having rotation stopper projections. At least (a) peripheral portions of the cover member and the casing member, which edge portions confront at least the thickened portion of the magnetic tape cassette, and (b) side wall portions of the cover member and the casing member, the side wall portions including the pivotably assembled portions, are molded with a resin, which is more slidable than the other portions of the cover member and the casing member. The other portions are molded with such a transparent resin as to allow the case to be seen through. A method for manufacturing such a magnetic tape cassette accommodating cage utilizes a first slide core slidable in a direction of inserting a cassette, and a second slide core movable substantially orthogonal to the direction of moving the first slide core.Type: GrantFiled: October 27, 1993Date of Patent: September 2, 1997Assignee: Fuji Photo Film Co., Ltd.Inventors: Shingo Katagiri, Teruo Ashikawa, Kiyoo Morita

Patent number: 5531394Abstract: A magnetic tape cassette includes a leaf spring and magnetic tape reels in which the depression force of the leaf spring is varied such that, in assembling the cassette, the leaf spring provides a relatively weak depression force thereby to facilitate cassette assembly, and when the cassette is in use, the leaf spring provides a relatively strong depression force to sufficiently depress the magnetic tape reels. The magnetic tape cassette also includes a pair of protrusions formed on the inner surface of the top wall of an upper half casing which can abut the arms of a leaf spring secured to the upper half casing, so that, in assembling the cassette, the leaf spring is bent until it is brought into contact with the protrusions. When the cassette is in use, the leaf spring is further bent with the protrusions serving as fulcra, thereby to increase its force of depression.Type: GrantFiled: August 20, 1992Date of Patent: July 2, 1996Assignee: Fuji Photo Film Co., Ltd.Inventors: Hidetoshi Hirata, Shingo Katagiri
