In a method for manufacturing a multilayer ceramic electronic device, a resin introduction portion located outside a vertically projected region of a surface mount electronic device is disposed on a seat portion which includes a non-metallic inorganic powder as a primary component and on which the surface mount electronic device, e.g., a semiconductor element, is mounted, and a resin is supplied to the resin introduction portion so as to fill the resin into the seat portion and a gap between the seat portion and a multilayer ceramic element assembly. Unsintered ceramic base material layers and shrinkage restriction layers arranged to restrict shrinkage of the unsintered ceramic base material layers in a direction substantially perpendicular to a thickness direction of the unsintered ceramic base material layers are laminated and, thereby, an unfired multilayer ceramic element assembly is formed, which does not shrink in a direction substantially perpendicular to a lamination direction in a firing step.

A host computer 80 for wholly controlling an electronic component mounting line displays a surface side image and a reverse side image which respectively show a surface side and a reverse side of a board having components mounted thereon, with the images being superposed; displays components mounted on the surface side of the board and components mounted on the reverse side in visually different modes; and designates and determines the positions of support places of a backup device on the displayed superposed image (step 108).

A lighting system for a moving walkway or escalator installation and a moving walkway or escalator installation with a lighting system is disclosed. The moving walkway or escalator installation comprises a plate belt or step belt and a balustrade. The lighting system comprises a light-permeable inner panelling of the balustrade which is formed by one or more mutually adjoining plates free of interruption as well as one or more lighting bodies which are mounted in corresponding sockets. The sockets are fastened in the interior of the balustrade to a mechanical structure. The inner panelling of the balustrade can be illuminated over a whole area by the lighting system.

A temperature indicator for a siding panel senses panel temperature and indicates on a graphic scale the corresponding effect of thermal expansion over differences in temperature. The temperature indicator can be various forms of contact thermometer, temperature strip or sensor and can be integral or temporarily affixed during installation or for later assessment for correct panel gapping. The indicator shows how closely the edge of the panel can be placed to an adjacent surface while avoiding interference over a range of thermal expansion temperatures.
