Publication number: 20140191731Abstract: CCCV charging is applied to a lithium ion secondary battery. During CC charging, a transition point Ta appears in temperature rise gradient when battery temperature rises along with the charging, and with the transition point Ta being a border, a temperature rise gradient in an initial T1 period is steeper than a temperature rise gradient in a T2 period following the T1 period. Based on charging time tT corresponding to timing at which the transition point Ta appears after start of the CC charging from a condition of the SOC of 0%, changeover time ts is set in a range of tT?ts?(tT×1.2). The CC charging is performed at a first current value until changeover time tS elapses after its start, and after the changeover time ts elapses, the CC charging is performed with a second current value larger than the first current value.Type: ApplicationFiled: September 4, 2012Publication date: July 10, 2014Applicant: HITACHI MAXELL, LTD.Inventor: Kazutoshi Miura

Patent number: 7978433Abstract: When a medium casing is properly inserted, a first pair of projections and a second pair of projections are passed through between a first bottom surface and a second bottom surface of a chassis in the moving direction and are thus prevented from coming into contact with the first and second bottom surfaces, thereby allowing for smooth insertion of the medium casing. In contrast, when the medium casing is inserted improperly from its wrong end, one of the projections on the lower surface of the medium casing comes into abutment with the second bottom surface of the chassis near the opening. Accordingly, an improperly inserted medium casing can be prevented from being inserted any further at an early stage of the insertion process.Type: GrantFiled: September 29, 2008Date of Patent: July 12, 2011Assignees: Alps Electric Co., Ltd., Imation CorporationInventors: Kazutoshi Miura, Kiyoyuki Ito

Publication number: 20090086371Abstract: When a medium casing is moved deep into a device, a reference guide pin with a greater length provided in a driving-device body is first inserted into a first positioning hole of the medium casing and a subsidiary guide pin is subsequently inserted into a second positioning hole. This implies that the medium casing is guided deep into the device on the basis of the reference guide pin having a greater diameter. Therefore, even when the medium casing is inserted in a displaced state in a direction orthogonal to the insertion direction, such displacement can be compensated for gradually with the movement of the medium casing. This ensures proper connection between a plurality of external terminals of the medium casing and a plurality of connector pins of the driving-device body.Type: ApplicationFiled: September 29, 2008Publication date: April 2, 2009Applicants: ALPS ELECTRIC CO., LTD., IMATION CORPORATIONInventors: Kazutoshi MIURA, Kiyoyuki ITO
