Patent number: 5770300Abstract: A metallic printed board is formed by laminating an insulation layer on the surface of a metallic sheet as a base, and then electronic parts are mounted on the conductor pattern formed on the surface of the insulation layer. A double-sided printed board mounted thereon electronic parts is placed in parallel. Both the printed boards are supported and fixed monolithically by filling the space between the printed boards with an insulation resin and curing the resin. Furthermore, an insulation resin is laminated on the surface of the printed board in such a manner that the resin may cover the mounted electronic parts, and cured. The heat generated from the electronic parts can be efficiently transmitted to the insulation resins by using a resin having a high thermal conductivity for both of the insulation resins, and the heat is then emitted from the surfaces of the metallic sheet or the insulation resin.Type: GrantFiled: December 3, 1996Date of Patent: June 23, 1998Assignee: Fuji Electric Co., Ltd.Inventors: Kenji Okamoto, Yukio Nakajima, Kazuhiko Imamura, Takao Ichihara

Patent number: 5717613Abstract: A method of determining a pitch arrangement of a tire, to design and develop a tire efficiently. An initial value of the pitch arrangement is determined corresponding to a set value. A model of a noise pulse generated in each pitch of the tire, the objective function representing a physical amount for evaluating noise performance of the tire, a design variable for determining the pitch arrangement, and a constraint for constraining the pitch arrangement are determined for the initial value, and the pitch arrangement whose objective function converges and is minimized is determined while satisfying a constraint by varying a design variable. A pitch ratio whose value of the objective function is minimized is determined by fluctuating of the pitch ratio while the first and the last pitch ratio are fixed among determined pitch arrangements. The pitch arrangement and the pitch ratio whose value of the objective functions are minimized are selected among the pitch arrangements for a hundred initial values.Type: GrantFiled: December 17, 1996Date of Patent: February 10, 1998Assignee: Bridgestone CorporationInventor: Yukio Nakajima

Patent number: 5710718Abstract: A method of designing a pneumatic tire, wherein a basic model of a tire representing a cross-sectional shape of the tire including an internal structure, an objective function representing a physical amount for evaluating tire performance, a design variable for determining the cross-sectional shape of the tire, and a constraint for constraining the cross-sectional shape of the tire are determined. A corrected model of the tire with the design variable changed by a unit amount .theta.r.sub.i is determined. The value of the objective function and the value of the constraint in the corrected model are calculated. A sensitivity is calculated for each design variable, and an estimated value of the amount of change of the design variable which maximizes the value of the objective function while taking the constraint is calculated by means of the sensitivities. The above process is repeated until the value of the objective function converges.Type: GrantFiled: September 16, 1994Date of Patent: January 20, 1998Assignee: Bridgestone CorporationInventors: Tatsuhiko Kamegawa, Yukio Nakajima, Akihiko Abe

Patent number: RE34140Abstract: Apparatus for adjusting a camera electric circuit employs a non-volatile memory element for electrically storing and reading data, takes out digitized compensation data from the non-volatile memory element during a digital calculation process, and, after the calculation including the compensation data, controls an exposure control or an exposure display circuit of the camera in accordance with the calculated output, thereby dispensing with conventional analog adjustment. The compensation data may be obtained through the use of a test instrument by comparing test results against results obtained by the camera calculator or through the use of comparing a previously standarized shutter speed with the shutter speed determined by the camera calculator. The compensation value can be used to provide a corrected display. A separate compensation value for an aperture deviation can also be stored. The stored data is retained unchanged by removal of a jumper control.Type: GrantFiled: April 11, 1990Date of Patent: December 8, 1992Assignee: Olympus Optical Company, Ltd.Inventor: Yukio Nakajima
