Patent number: 4754319Abstract: In an IC card according to the present invention, a base sheet formed of thermoplastic material is sandwiched between a substrate sheet and a dummy sheet both formed of nonplastic material lower in thermoplasticity than the base sheet. The substrate sheet is fitted with at least one IC chip and input/output terminals electrically connected to the IC chip. First and second cover sheets formed of thermoplastic material are put individually on the outer surfaces of the substrate sheet and the dummy sheet. The cover sheet on the substrate sheet is formed with apertures through which the input/output terminals are exposed to the outside.Type: GrantFiled: September 11, 1987Date of Patent: June 28, 1988Assignees: Kabushiki Kaisha Toshiba, Shoei Printing Company LimitedInventors: Tamio Saito, Masayuki Ohuchi, Hirosi Oodaira, Yoshikatsu Fukumoto, Shuji Hiranuma, Ko Kishida, Takanori Kisaka

Patent number: 4704318Abstract: There is disclosed a wiring substrate comprising a wiring circuit pattern formed on a metal substrate with an insulating resinous layer interposed therebetween. In this wiring substrate, the insulating resinous layer is formed of a high molecular composition comprising thermosetting 1,2-polybutadiene containing 5 to 30% by weight of a high molecular softening agent such as hydrogenated polybutadiene. A method of manufacturing such a wiring substrate is also disclosed, wherein a light-reflecting pigment is included in the insulating resinous layer for the convenience of the subsequent laser trimming.Type: GrantFiled: March 12, 1986Date of Patent: November 3, 1987Assignee: Kabushiki Kaisha ToshibaInventors: Masayuki Saito, Hirosi Oodaira

Patent number: 4694138Abstract: A conductor path is formed by providing an insulating substrate having a surface region which is formed of an insulating composition. The insulating composition contains an organic polymeric material and at least one metal source. The metal source is a metallic powder and/or an organic compound chemically combining a metal or metals. The surface region of the substrate is selectively heated along a predetermined pattern, thereby decomposing and evaporating the organic polymeric material at the heated portion and welding the metal in the heated portion so as to form a conductor path formed of the metal.Type: GrantFiled: November 30, 1984Date of Patent: September 15, 1987Assignee: Kabushiki Kaisha ToshibaInventors: Hirosi Oodaira, Haruko Suzuki, Masayuki Saito, Masayuki Ohuchi

Patent number: 4635356Abstract: Terminal-equipped electronic elements, such as chip resistors and chip diodes, are arranged such that one surface of each terminal contacts one surface of a support board, the support board being placed to face a flat plate through a spacer. An electrically insulative liquid synthetic resin is injected between the support board and the flat board and cured to form a synthetic resin layer burying the electronic elements. The support board, flat board and spacer are peeled from the electronic elements and the synthetic resin layer to expose one surface of the terminal of each electronic element on one surface of the synthetic resin layer. A conductive pattern is formed on the synthetic resin layer by screen printing to connect the terminals of the electronic elements.Type: GrantFiled: August 15, 1985Date of Patent: January 13, 1987Assignee: Kabushiki Kaisha ToshibaInventors: Masayuki Ohuchi, Hirosi Oodaira, Kenichi Yoshida

Patent number: 4584456Abstract: A resistor is formed by locally heating an insulating material layer between conductors to convert the heated material into a first resistor element. A second resistor element is formed to contact the first resistor element while measuring the resistance between the conductors, until a desired resistor composed of the first and second resistor elements and having a predetermined resistance value is obtained.Type: GrantFiled: September 7, 1983Date of Patent: April 22, 1986Assignee: Tokyo Shibaura Denki Kabushiki KaishaInventors: Hirosi Oodaira, Haruko Suzuki, Masayuki Saito, Nobuo Iwase

Patent number: 4572843Abstract: A method for producing a capacitor includes the steps of: forming on a dielectric layer formed on a first electrode, an insulating composition, e.g., an organic polymeric compound containing a metal powder or an organometallic compound as a metal source, which is rendered conductive upon heating by radiation; and locally and gradually heating the insulating composition layer so as to form a second conductive electrode while measuring an increase in a capacitance between a conductor end portion for measuring a capacitance and the first electrode. According to this method, a capacitor having a precise capacitance can be formed.Type: GrantFiled: February 1, 1985Date of Patent: February 25, 1986Assignee: Kabushiki Kaisha ToshibaInventors: Masayuki Saito, Haruko Suzuki, Hirosi Oodaira
