Patent number: 7268417Abstract: A electronic circuit device is provided with an electronic component provided with an electrode, a substrate having an upper surface on which the electronic component is mounted, external electrode that is formed near the electronic component mounted on the upper surface of the substrate and that is connected to the electrode, an insulating protrusion that is provided across the upper surface of the external electrode, and a sealing resin that seals the electronic component without covering the external electrode. The upper surface of the external electrode is partitioned by the protrusion into a first area that is located on the sealing resin side and a second area that is located the side opposite to the first area. The adherence of fine particles such as flakes of the sealing resin to the external electrode is suppressed, so that a stable electric connection between the external electrode and the electric equipment can be maintained.Type: GrantFiled: April 22, 2003Date of Patent: September 11, 2007Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takao Ochi, Takashi Takata

Patent number: 7009824Abstract: An actuator, operated by being supplied with electric power, needs an initial setting for performing a desired operation by recognizing its starting position. The initial setting is conducted when an abnormality occurs in a signal which represents an operation of the actuator. The initial setting is also conducted when a system for the actuator recognizes a fact that a battery is electrically disconnected in association with information denoting a condition of the battery in a memory.Type: GrantFiled: June 20, 2003Date of Patent: March 7, 2006Assignee: DENSO CorporationInventors: Tokuhisa Takeuchi, Takashi Takata

Patent number: 6917178Abstract: In determining a starting point of a motor of an electric actuator during its initialization procedure, when a rotation angle sensor detects pulse signals in a certain initialization pattern, power supply to the motor is stopped by the control of a motor drive circuit. This electrical control of motor rotation enables the initialization procedure of the actuator to be carried out without using mechanical restriction means for locking purposes, and the influence of variations in the deflection amount of any stoppers is eliminated. The precision in determining the starting point in the initialization procedure is thus improved.Type: GrantFiled: December 12, 2003Date of Patent: July 12, 2005Assignee: DENSO CorporationInventors: Tokuhisa Takeuchi, Takashi Takata, Nobukazu Kuribayashi, Masahiko Sugaya

Patent number: 6801007Abstract: A motor stopping circuit is activated when a motor control circuit is stopped by a reset signal outputted from a reset circuit. This maintains an overrun angle small. As a result, a difference between a rotation angles measured when the motor control circuit is turned off and measured when the motor control circuit is turned on are small. Therefore, frequent origin setting operation is not required. This reduces sizes and manufacturing costs of a stopper and an actuator.Type: GrantFiled: July 3, 2003Date of Patent: October 5, 2004Assignee: DENSO CorporationInventors: Tokuhisa Takeuchi, Takashi Takata
