Patent number: 8402614Abstract: A separable bottom end stop in which a box pin has a box pin body, a first notch portion for receiving the head end of a locking pawl of a reverse-opening slider, and a protrusion piece projecting toward a separable pin in the direction of the tape width from a separable pin facing surface opposed to the separable pin. A side wall surface of the first notch portion and that sectional surface of the protrusion piece which is provided to the front end side of the box pin are formed in one plane to constitute a locking plane with which the front end of the locking pawl makes contact to lock the reverse-opening slider. The box pin body and the protrusion piece have a slant surface declined from the position of the locking plane toward an element row.Type: GrantFiled: December 12, 2008Date of Patent: March 26, 2013Assignee: YKK CorporationInventor: Takaaki Fujii

Patent number: 8349259Abstract: A biosensor includes a cavity for holding a sample, an electrode system for measuring the sample concentration in the cavity, and a thermocouple for obtaining temperature information during measurement. A measurement device includes a reference temperature junction sensor or an environmental temperature sensor for measuring the temperature of reference temperature junctions of the thermocouple. A temperature compensation measures the temperature difference between a measuring junction and a reference temperature junctions of the thermocouple, and specifies the temperature of a reference temperature junction, thereby using the temperature information as the temperature of a measurement component and performing accurate temperature compensation from the measuring junction temperature information and the environmental temperature information with respect to the measured values.Type: GrantFiled: June 16, 2009Date of Patent: January 8, 2013Assignee: Panasonic CorporationInventors: Takaaki Fujii, Yoshifumi Takahara, Noriyoshi Terashima

Patent number: 8120151Abstract: An optical semiconductor device can have a first lead for an optical semiconductor chip to be mounted on and a second lead for joining to a wire extending from the optical semiconductor chip. The device can be configured to be capable of reducing the possibility of a break of the wire even under a thermal shock and the like. The optical semiconductor device can include a first lead for an optical semiconductor chip to be mounted on, a second lead for joining to a wire (for example, gold wire) extending from the optical semiconductor chip mounted on the first lead; a holder part for supporting the first lead and the second lead at two locations each; a lens part; and a light-transmitting sealing part. The second lead can be separated into two lead pieces with a predetermined gap (?0) therebetween as seen in a plan view, or with certain bend configurations as shown in side views, within the inside space of the holder part by which the second lead is supported at two locations.Type: GrantFiled: April 18, 2008Date of Patent: February 21, 2012Assignee: Stanley Electric Co., Ltd.Inventors: Kazuhisa Ishi, Takaaki Fujii, Hiroaki Okuma, Aki Hiramoto

Publication number: 20090325205Abstract: A biosensor 1 comprises a cavity 17 for holding a sample, an electrode system 14 for measuring the sample concentration in the cavity 17, and a thermocouple 16 for obtaining temperature information during measurement. A measurement device 2 comprises a reference temperature junction sensor 33 or an environmental temperature sensor 22 for measuring the temperature of reference temperature junctions 42 and 43 of the thermocouple. A temperature compensation step S9 involves measuring the temperature difference between a measuring junction 41 and a reference temperature junctions 42 and 43 of the thermocouple 16, specifying the temperature of a reference temperature junction, thereby using these temperature information as the temperature of a measurement component 18 and performing accurate temperature compensation from the measuring junction temperature information and the environmental temperature information with respect to the measured values.Type: ApplicationFiled: June 16, 2009Publication date: December 31, 2009Inventors: Takaaki Fujii, Yoshifumi Takahara, Noriyoshi Terashima

Patent number: 5690186Abstract: A control apparatus of an electric vehicle for effectively limiting the operation of the vehicle when it is determined that a driver of the electric vehicle is not sitting in the seat and an accelerator opening of the electric vehicle is in a position corresponding to a minimum value. A motor driving enablement circuit generates a motor driving command which selectively limits operation of the electric vehicle in accordance with these determinations. In addition, when a state in which the driver is not occupying the seat continues for a period of time exceeding a predetermined value, a motor halt controller issues a motor halt command for halting a motor of the electric vehicle. Based on the motor driving enablement command and the motor halt command, a power supply controller controls the supply of power to the motor of the electric vehicle.Type: GrantFiled: September 17, 1996Date of Patent: November 25, 1997Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Kouichi Sugioka, Hiroyuki Sinmura, Masao Ogawa, Satoshi Honda, Yoshihiro Nakazawa, Takaaki Fujii

Patent number: 5644202Abstract: A regenerative braking control system consumes energy generated in a period corresponding to an angle .theta..sub.1 which starts in a half of a period of an AC voltage produced in a drive motor during the braking of the drive motor. The regenerative braking control system also consumes energy generated in a period corresponding to an angle .theta..sub.2 that ends at the end of a half of a period of the AC voltage. The regenerative rate of braking control system utilizes a current induced in the driving coils of the drive motor at the end of the period corresponding to the angle .theta..sub.1 to recharge a battery. By utilizing two periods to carry out the regenerative braking process, the recharging energy and the braking force can be controlled individually. Moreover, a controller monitors the electric control system to determine whether a malfunction is present. If a malfunction is detected, an electrical brake electrically brakes the drive motor.Type: GrantFiled: January 26, 1996Date of Patent: July 1, 1997Assignee: Honda Giken Kogyo Kabushiki KaishaInventors: Masayuki Toriyama, Kenji Tamaki, Satoshi Honda, Shoji Motodate, Yoshihiro Nakazawa, Takaaki Fujii, Shigemi Sasaki
