Title: Bonded structure for electronic circuit device

IPC: H05K1/02
Filed: 2003-02-14
Abstract: <P>PROBLEM TO BE SOLVED: To provide a bonded structure for an electronic circuit device, which makes uniform the thickness of a bonding agent in between a circuit board and a base during the process of bonding, and hardening in between the two for further improving on heat radiation performance and reliability.  <P>SOLUTION: When a bonding agent 5 is applied for bonding together a circuit board 3 and a base 4 with protrusions such as printed resistors crowding on an edge of the circuit board 3, an unsupported part droops under the weight of the circuit board 3 and this makes the bonding agent 5 thinner at the unsupported part. Since the bonding agent 5 at a protrusion-occupied part cannot be thinner than the thickness of the protrusion, a difference may occur there in the thickness of the bonding agent 5 when it is hardened. Heat radiation performance may grow irregular in the presence of a local difference in bond layer thickness, and this threatens separation of bonded surfaces. When protrusions 7 are built so that protrusions in the bonded surfaces between the circuit board 3 and the base 4 are arranged uniformly, the circuit board 3 is kept in equilibrium for the thickness of the bonding agent 5 to be prevented from growing uneven.  <P>COPYRIGHT: (C)2004,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide a vehicle detection system which has high detection precision by reducing misrecognition of a vehicle without spoiling the beauty and can reduce the power consumption.  <P>SOLUTION: A sensor which senses infrared rays that an object to be detected radiates measures an input level value. A sense processing part decides whether there is a vehicle by using the input level value obtained from the sensor. It is decided whether there is a vehicle by computing a background level from the input level value based upon infrared rays except from the vehicle, comparing it with the value (comparison value) based upon the difference between the input level value and background level, and using their large/small relation. The power consumption is reduced by using the sensor which passively senses the infrared rays and the detection precision does not decrease even when the infrared rays are sensed from by the lateral of the vehicle.  <P>COPYRIGHT: (C)2004,JPO
