Title: Conductive paste and multilayer ceramic substrate
Inventor: NOMIYA MASATO
IPC: H01L23/498
Filed: 2004-11-10
Abstract: Disclosed is a conductive paste which is used for forming a wiring conductor such as a via hole conductor (15) arranged in a multilayer ceramic substrate (11). This conductive paste enables to comparatively arbitrarily control the temperature range within which sintering of the conductive paste occurs during a firing step. Such a conductive paste contains a metal powder, a glass frit and an organic vehicle. An inorganic component, which is not sintered at a temperature at which a ceramic layer (12) of the multilayer ceramic substrate (11) can be sintered in the firing process, is arranged on the surface of each particle of the metal powder. The glass frit has a softening point lower than the above-mentioned sintering temperature by 150-300°C.

Title: Program data file storage method and authenticated program execution method
Inventor: TERAO SATOSHI
IPC: H04N21/443
Filed: 2004-12-15
Abstract: Conventionally, when the version of a program has been upgraded, the whole of a currently stored program needs to be deleted to be replaced by a new program, and authentication needs to be performed again on such new program when it is activated. However, since the whole of the program is required to be stored and authenticated even when only a part of such program has changed, it consumes time and leads to the decrease in responsiveness. In order to solve this problem, the present invention extracts a difference between a new program and a currently stored old program, when such new program is to be stored, and the new program is to be stored after authentication is performed only on such difference.

Abstract: A fuel cell module, wherein slopes of a same angle Theta relative to a bottom face are formed on both side faces to form a recessed groove in a tapered shape. Since the angle Theta is provided to the side faces of the recessed groove, the exhaustion of gases from the accumulation of gases to the outside can be assisted by the side faces with the angle Theta more than in a case where the side faces of the recessed groove are formed in right angled shapes even if the accumulation of gases is produced between an adhesive agent and the inner surfaces of the recessed groove when first and second separators are joined to each other for modularization by covering the first separator on the second separator. Thus, the accumulation of the gases can be prevented from occurring. ® KIPO & WIPO 2007
