Patent number: 7748594Abstract: A solder repairing apparatus includes a stage designed to place the surface of at least a specific part of an object along a reference plane within a specific spot defined on the stage. A heating unit applies a thermal energy to the specific spot. A dividing plate is designed to move into the specific spot in a vertical attitude perpendicular to the reference plane. The dividing plate exhibits a low solder wettability. The solder melts in response to the application of the thermal energy. When the dividing plate in the vertical attitude enters the specific spot, the dividing plate gets into the solder. Since the dividing plate exhibits a low solder wettability, the dividing plate repels the solder. The solder is divided into two parts. The division of the solder reliably eliminates a short circuit in the electronic circuit.Type: GrantFiled: July 14, 2008Date of Patent: July 6, 2010Assignee: Fujitsu LimitedInventors: Keiichi Yamamoto, Toru Okada

Publication number: 20090096923Abstract: A sync separation circuit separates a synchronizing signal from a video signal containing the synchronizing signal. A minimum level detecting section detects a minimum level of a video signal. A sync tip level detecting section detects a sync tip level in the video signal. A pedestal level detecting section detects a pedestal level in the video signal. Based on both the sync tip level detected by the sync tip level detecting section and the pedestal level control by the pedestal level detecting section, a slice level setting section sets a slice level corresponding to an intermediate value between the sync tip level and the pedestal level. The slice level control section sets the slice level based on the minimum level detected by the minimum level detecting section if the slice level set based on the sync tip level and the pedestal level is inappropriate.Type: ApplicationFiled: October 10, 2008Publication date: April 16, 2009Applicants: SANYO ELECTRIC CO., LTD., SANYO SEMICONDUCTOR CO., LTD.Inventors: Toru Okada, Hiroyuki Ebinuma

Publication number: 20080296266Abstract: A processing head is supported for pivotal movement around a pivot point in a processing apparatus. An urging member applies an urging force to the processing head at the pivot point. The processing apparatus allows establishment of point contact between the urging member and the processing head. When the surface of an object inclines from a predetermined attitude, the processing head is allowed to follow the inclination of the surface. The processing head is allowed to establish a predetermined attitude relative to the surface of the object. The processing head thus reliably enables a predetermined action to the object as desired.Type: ApplicationFiled: May 22, 2008Publication date: December 4, 2008Applicant: FUJITSU LIMITEDInventors: Toru Okada, Yutaka Noda, Seiichi Shimoura

Patent number: 7436062Abstract: An apparatus and method for improving the underfill filling of a semiconductor chip element 100 which is ultrasonically bonded to and mounted on a circuit board. A semiconductor chip element 100 includes a silicon chip 101 and a group of stud bumps 117 formed on a bottom surface 101a of the chip 101. Signal stud bumps 113 are made of gold while power stud bumps 114, ground stud bumps 115 and dummy stud bumps 116 are all made of a gold-palladium alloy, which are harder than the signal stud bumps 113 and thus do not deform easily during ultrasonic treatment. Therefore, in a state in which the semiconductor chip element 100 is mounted, a gap of approximately 30 ?m is maintained between the bottom surface 101a of the chip 100 and a top surface of the circuit board 120 on which the semiconductor chip element 100 is mounted.Type: GrantFiled: August 20, 2002Date of Patent: October 14, 2008Assignee: Fujitsu LimitedInventors: Norio Kainuma, Shunji Baba, Hidehiko Kira, Toru Okada
