Title: Power module structure, power module having the same structure, and manufacturing method of the same structure
Inventor: YAMATAKE ATSUSHI
IPC: H01L23/13
Filed: 2011-02-28
Abstract: PROBLEM TO BE SOLVED: To obtain a structure capable of obtaining reduced substrate size, mitigated stress and defect suppression effect with a reduced gap between upper and lower metallic layer ends, while maintaining the electric field mitigation effect, in a power module structure having a mitigated electric field of a high electric field point by changing the gap between the upper and lower metallic layer ends of an insulation substrate.SOLUTION: A gap between an upper metallic layer end portion 7 and an insulation substrate end portion 9 is made smaller than a gap between a lower metallic layer end portion 8 and the insulation substrate end portion 9. Also, an insulator 10, having a lower dielectric constant than the dielectric constant of an insulation sealing material 6, under the substrate is filled into a space between the insulation substrate 1 and a metallic base plate 4. As a result, the reduced substrate size, the mitigated stress and the defect suppression effect are achieved by the reduction of a gap (a) between the upper and lower metallic layer ends while the electric field mitigation effect is maintained.

Filed: 2011-02-28
Abstract: PROBLEM TO BE SOLVED: To make it possible to continue communication by allowing loopback even if a logical disconnection state occurs such that normal communication cannot be performed although electric connection is maintained.SOLUTION: A master station 1 generates and transmits a disconnection detection frame to adjacent slave stations #1 (2), #4 (5) when detecting continuous transmission failures. The slave station #4 (5) responds when it receives the disconnection detection frame, and if its own station is not an end terminal station, it transmits the disconnection detection frame to an adjacent station #3 (4) other than the transmission source station. Then, the slave station #4 (5) performs loopback regarding its own station as an end terminal station, if it cannot receive a response from the adjacent station #3 (4) even when a prescribed time has elapsed since it sent the disconnection detection frame.

Abstract: PROBLEM TO BE SOLVED: To prevent an alignment film from being shaved by a columnar spacer, in a liquid crystal display device of an IPS method using optical alignment.SOLUTION: At a part where a columnar spacer 204 formed on a counter substrate 200 contacts with a TFT substrate 100, a pedestal 114 which is higher than a pixel electrode 108 is formed. When an alignment film 113 of a two-layer structure is applied on the pixel electrode 108 and the pedestal 114, the alignment film 113 on the pedestal 114 is made to be thin due to a leveling effect. When subjected to optical alignment in the state, a photodegraded upper alignment film 112 on the pedestal is disappeared, and a lower alignment film 111 having large mechanical strength remains. Therefore, the alignment film can be prevented from being shaved. On the other hand, on the pixel electrode 108, the upper alignment film 112 is originally thick, and can ensure predetermined film thickness for aligning liquid crystal.
