Patent number: 11961059Abstract: The present disclosure promotes distribution of sensor data among a plurality of business operators. A controller that an information processing system according to the present disclosure includes collects first data including a plurality of items and personal information from mobile bodies belonging to a first business operator. The controller converts the first data to second data not being usable to identify individuals. The controller provides data in a range decided based on content of a predetermined data use contract, among the second data, to a second business operator. The controller calculates a consideration for the data that is to be paid by the second business operator, based on a data use record of the second business operator.Type: GrantFiled: August 24, 2021Date of Patent: April 16, 2024Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Nobuaki Matsueda, Takashi Sueki, Jun Okamoto, Takumi Wada, Ryo Midorikawa, Junichi Nonaka, Wataru Shiraishi, Yasuhisa Fujiwara, Hiroshi Ishikawa, Shigeru Ichikawa, Hidetaka Eguchi, Masayo Nagai, Mika Inaba

Publication number: 20110316486Abstract: The charge control system includes at least a battery temperature control device, a cooling device, a heating device, and an integrated control device. The battery control device detects SOC of a battery. Based on the detected SOC, the integrated control device switches between a first charging mode in which the battery is charged at a substantially constant current and a second charging mode in which the battery is charged at a substantially constant voltage. In the second charging mode, the battery temperature control device performs rapid cooling control to control the cooling device such that it has a cooling capacity in the second charging mode higher than a cooling capacity in the first charging mode. Thus, the battery temperature is appropriately controlled to increase a cruising distance even when the electric vehicle is run immediately after completion of charging.Type: ApplicationFiled: June 28, 2011Publication date: December 29, 2011Applicant: Hitachi, Ltd.Inventors: Ryo INABA, Naoyuki Tashiro

Patent number: 5627012Abstract: An optical recording medium is prepared by forming on a substrate a phase change recording layer comprising elements A, B, C and optional D wherein A is silver and/or gold, B is antimony and/or bismuth, C is tellurium and/or selenium, D is indium or a mixture of indium and aluminum and/or phosphorus. Formation of the recording layer is carried out by the step of sputtering an A--C base metal and the step of sputtering a B base metal optionally containing D in this successive order or reverse order; or by the step of sputtering an A--C base metal, the step of sputtering a B base metal, and the step of sputtering a D base metal in this successive order or reverse order. Since the resulting recording layer is already crystallized, the method eliminates a need for extra initialization.Type: GrantFiled: February 9, 1996Date of Patent: May 6, 1997Assignee: TDK CorporationInventors: Junji Tominaga, Ryo Inaba, Susumu Haratani

Patent number: 5569517Abstract: An optical information medium has on a substrate (2) with information-carrying pits (21), a light transmittance control layer (3) including a lower dielectric layer (31), a mask layer (32) and an upper dielectric layer (33). The mask layer has an original state before irradiation of reading light. Upon irradiation of a reading light beam to define a beam spot, the mask layer undergoes a crystal-to-crystal transition in a region (H) of the beam spot depending on the intensity distribution of the beam spot. Multiple reflection condition changes in the transition portion so that the beam spot contributing to read-out is limited to the transition or transition-free region (H or L). The transition temperature is in the range of 200.degree. to 450.degree. C. The mask layer returns to the original state after passage of the beam spot. The invention is also applicable to an optical recording medium having a recording layer above or below the transmittance control layer.Type: GrantFiled: June 5, 1995Date of Patent: October 29, 1996Assignee: TDK CorporationInventors: Junji Tominaga, Susumu Haratani, Ryo Inaba, Tsuneo Kuwahara

Patent number: 5523140Abstract: A phase change type optical recording medium has a recording layer of a recording material containing elements A, B, and C wherein A is Ag and/or Au, B is Sb and/or Bi, and C is Te and/or Se. Information is recorded by directing a light beam to the recording layer to form recorded marks therein such that the recorded marks are amorphous or microcrystalline while an unrecorded portion of the recording layer remains crystalline, and the A concentration of the unrecorded portion is at least 0.5 atom % higher than the A concentration of the recorded marks. C/N and modulation factor are improved and such improvements are kept even after hot humid storage.Type: GrantFiled: March 8, 1995Date of Patent: June 4, 1996Assignee: TDK CorporationInventors: Junji Tominaga, Tokuhiko Handa, Susumu Haratani, Ryo Inaba

Patent number: 5470628Abstract: An optical recording medium has a mask layer 4, an intermediate dielectric layer 5, a recording layer 6, and a reflective layer 8 on a transparent substrate 2. The recording layer 6 contains a recording material which changes its crystallographic structure upon exposure to recording light for recording information. The mask layer 4 contains a mask material which increases its light transmittance when melted and has a complex refractive index (n.sub.0 -ik.sub.0), of which the real part n.sub.0 drops by 1.0 or less and the imaginary part k.sub.0 drops by 0.25-1.0 when the mask material converts from a crystalline state to an amorphous or microcrystalline state. Signals can be reproduced from the medium with high C/N without resorting to reading light of shorter wavelength or an optical pickup objective lens having a larger numerical aperture and even when the linear velocity of the medium relative to recording and reproducing light is low.Type: GrantFiled: November 14, 1994Date of Patent: November 28, 1995Assignee: TDK CorporationInventors: Junji Tominaga, Susumu Haratani, Tokuhiko Handa, Ryo Inaba
