Patent number: 7549566Abstract: A heating characteristic value at any measuring point of an object at any measuring location of a heating furnace is determined as a single invariable by using temperature (Tint and Ts) measured at the measuring point of the object and heating temperature (Ta) and heating time (t) at the measuring location of the heating furnace. The heating characteristic value (m-value) may be calculated without using physical characteristics of the object. By using the m-value, a temperature profile of the object heated under a modified heating condition may be simulated in a short period of time without actually heating and measuring the temperature of the object at a high accuracy level. By using such a simulation, an appropriate heating condition for heating an object in accordance with a desired heating condition may easily be determined.Type: GrantFiled: July 30, 2003Date of Patent: June 23, 2009Assignee: Panasonic CorporationInventors: Masaru Nonomura, Yoshinori Isobata, Hiroaki Onishi, Masahiro Taniguchi

Publication number: 20080108480Abstract: A control apparatus for a shift-position changing mechanism includes a detection unit that is provided on a path along which the operation member with a magnetic member moves, and that detects a change in the magnetic field due to a positional change of the operation member; and a determination unit that determines the shift position corresponding to the operated position of the operation member based on the detected change in the magnetic field and predetermined multiple modes of changes in the magnetic field, which correspond to the respective shift positions. The predetermined modes are set such that, when the detected change in the magnetic field is influenced by a change in the magnetic field due to a factor different from the positional change of the operation member, a likelihood that the determination unit determines that the running shift position, at which a vehicle is able to run, is selected is reduced.Type: ApplicationFiled: October 23, 2007Publication date: May 8, 2008Applicants: TOYOTA JIDOSHA KABUSHIKI KAISHA, KABUSHIKI KAISHA TOKAI-RIKA-DENKI-SEISAKUSHOInventors: Atsushi Kamada, Masahiro Taniguchi

Patent number: 6496002Abstract: A rotation detector includes a rotor having a shaft. Projections are located at predetermined intervals on the periphery of the rotor and extend in an axial direction. Magnets are located between the projections and the shaft. The flux of each magnet is detected by a corresponding magnetism detection element. Each magnetism detection element has magnetic resistors. Movement of the projections changes the direction of flux of the magnets. Each resistor is switched between a first state, in which its magnetic resistance is great, and a second state, in which its magnetic resistance is small, in accordance with the change of the flux direction. The resistors are divided into two groups. The groups are substantially symmetrical relative to a centerline of the groups such that, when the direction of the flux changes, the resistors in one group are in the opposite state from the resistors in the other group. The centerline of changes in the direction of the flux matches the centerline of the resistor groups.Type: GrantFiled: March 9, 2000Date of Patent: December 17, 2002Assignee: Kabushiki Kaisha Tokai Rika Denki SeisakushoInventors: Katsuya Kogiso, Yasushi Nishibe, Masahiro Taniguchi, Shinji Usui

Patent number: 6402011Abstract: For reflow soldering, radiant heating is applied to one surface of a printed circuit board on which electronic components are placed and onto which cream solder is supplied and at the same time hot air is blown locally and roughly perpendicular to to-be-connected points on said one surface of the printed circuit board. This reflow method permits secure soldering even if the hot air is set at a temperature not exceeding the heat resistance of the electronic components, which is possilbe because of its combination with the radiant heat. Moreover, this reflow method can permit soldering in such a manner that only the to-be-connected points are heated selectively, because the hot air is blown locally and roughly perpendicular to the points to be connected. Thus, this reflow method prevents heat damage to other sections than the to-be-connected points and ensures that the solder at the to-be-connected points is melted.Type: GrantFiled: August 4, 2000Date of Patent: June 11, 2002Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Masahiro Taniguchi, Kazumi Ishimoto, Koichi Nagai, Osamu Yamazaki, Tatsuaki Kitagawa, Osamu Matsushima, Kazuhiro Uji, Seizo Nemoto
