Publication number: 20100198438Abstract: A hybrid vehicle 1 includes as drive sources an internal combustion engine 20, to which fuel stored in a fuel tank 21 is supplied, and a second M/G 32, to which electricity stored in a battery 40 is supplied. The vehicle 1 also includes a battery charger 70 for charging the battery 40 from the outside of the vehicle 1. For each of a plurality of refuelings to the fuel tank 21, the history of the time of refueling and the amount of refueling are stored. Based on the history, the degree of deterioration of fuel in the fuel tank 21 is calculated.Type: ApplicationFiled: March 30, 2009Publication date: August 5, 2010Applicant: Toyota Jidosha Kabushiki KaishaInventors: Yumi Iraha, Tomoyuki Maruyama

Publication number: 20100179010Abstract: A hybrid vehicle power transmission device provided with a power distribution mechanism composed of a planetary gear device for distributing motive power of a drive source to a motor and an output shaft is further provided with a damper device in a power transmission path between the power distribution mechanism and a first motor. Consequently, the damper device receives only reaction torque dealt by the first motor through the power distribution mechanism with respect to drive torque of an engine. Thus, since the torque transmitted to the damper device is smaller than the drive torque of the engine, the torque capacity of the damper device can be decreased and the size of the damper device can be reduced. As a result, the overall size of the power transmission device can be similarly reduced.Type: ApplicationFiled: November 23, 2009Publication date: July 15, 2010Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Tetsuro KUZUYA, Ryuji Ibaraki, Kenji Odaka, Yuji Iwase, Tatsushi Takenaka, Tomoyuki Maruyama, Koichi Kondo

Patent number: 6694268Abstract: A leakage inspection method for a sealed container in which a liquid of a non-electrolyte is contained for judging whether a defect exists in the container, the method comprising the steps of applying an inspection AC voltage through electrodes from an inspection power source unit; detecting an AC current flowing through the container and the contained liquid by means of a current detector; obtaining a digital value corresponding to an absolute value of the instantaneous value of the detected AC current; successively totaling the digital values during a totaling period having a specific relation to the waveform of the AC current whereby the total value of the digital values corresponding to the absolute values of the respective instantaneous values of the AC current is arithmetically operated and judging that the defect exists in the container when the total value as the value to be judged is larger than a setting value.Type: GrantFiled: June 11, 2002Date of Patent: February 17, 2004Assignee: Rieckermann (Japan) Ltd.Inventor: Tomoyuki Maruyama

Publication number: 20030203354Abstract: A method for screening an apoptosis inhibitor characterized by screening a candidate via an effect on PGT. A cell protecting agent containing as the active ingredient a substance which can be incorporated into cells via prostaglandin transporter (PGT); and a screening method therefor comprising measuring the uptake into cells via PGT. An apoptosis inducer containing as the active ingredient a substance having a PGT inhibitory effect; and a screening method therefor comprising measuring the ability to induce apoptosis of cells with the expression of PGT. Because of having a cell apoptosis inhibitory effect, the cell protecting agent is useful as a nerve cell apoptosis inhibitor, a nerve cell protecting agent, etc. and applicable to the prevention or treatment of nervous diseases, etc. The apoptosis inducer is useful in preventing and/or treating diseases in association with cell proliferation such as tumor, etc.Type: ApplicationFiled: June 11, 2003Publication date: October 30, 2003Applicant: MITSUBISHI PHARMA CORPORATIONInventors: Tooru Kawamura, Satoshi Horie, Toshiaki Akira, Norifumi Nakamura, Tomoyuki Maruyama, Kazutaka Hayashi

Patent number: 6570149Abstract: There is disclosed a photodetector which is capable of attaining an enhanced detection accuracy, and at the same time permits reduction in the size and manufacturing costs thereof. An avalanche photodiode detects an incident light, in a state of a predetermined bias voltage set thereto. A cooler cools the avalanche photodiode to a predetermined cooling temperature. An amount of an incident signal light incident on the avalanche photodiode is detected based on a detection signal from the avalanche photodiode. A control block adjusts at least one of the bias voltage and the predetermined cooling temperature, thereby holding a value of the detection signal from the avalanche photodiode generated in a state of the incident light being blocked from impinging on the avalanche photodiode, within a predetermined tolerance range.Type: GrantFiled: March 21, 2001Date of Patent: May 27, 2003Assignee: Hioki Denki Kabushiki KaishaInventors: Tomoyuki Maruyama, Makoto Kudo, Fumio Narusawa

Patent number: 5088768Abstract: A structure for a shock energy absorbing type steering apparatus is disclosed in which a column jacket in which a bracket member, rotatably fixed to a clamp, is attached to a vehicle body linked to a column jacket by means of welding and an enclosing body is extended in a space between the bracket member and clamp so as to enclose an upper surface area of the bracket member, thus preventing a foreign matter from invading into the inside of the bracket member. In addition, the bracket member includes a front wall to which the column jacket is perpendicularly fixed, curling portions formed on both side ends of the front wall, rollers inserted into the corresponding curling portions, and side walls extended from the curling portions in parallel to the column jacket, and cut-out portions formed on a portion of the bracket member below the curling portions.Type: GrantFiled: June 26, 1990Date of Patent: February 18, 1992Assignee: Fuji Kiko Company, LimitedInventors: Tomoyuki Maruyama, Yoshiyuki Shimizu

Patent number: 4702722Abstract: A universal joint yoke is obtained from a flat blank of sheet metal whose general shape is that of a cruciate form having a circular base and two diametrically opposing small semielliptical extensions. The blank of sheet metal is pressed in a forming apparatus so that the two extensions are bent perpendicularly to the circular base in the same direction with a given angle with respect to the circular base and two ribs or contiguous rib are formed along axes of bending to prevent a springback action of the two extensions which constitute two ear portions of the finished yoke. In addition, recesses are extended along a rear surface(s) of the rib(s) so that fasteners such as bolts and nuts for fastening a rubber coupling constituting a lower joint to a lower shaft of a steering system is nestled into the respective recesses. Both ends of the circular base have holes through which the fasteners for fastening the universal joint yoke to the rubber coupling is inserted.Type: GrantFiled: February 18, 1986Date of Patent: October 27, 1987Assignee: Fuji Kiko Company, LimitedInventors: Atsushi Narue, Shigeru Saitoh, Tomoyuki Maruyama
