Abstract: Inexpensive methods for producing small-sized monolithic electronic parts with improved functions by which an electroconductive film can be formed uniformly, thin, and in fine patterns on a ceramic green sheet, a carrier film, or a resin film, for example. A plurality of such ceramic green sheets, etc., each having the electroconductive film formed thereon, are laminated to give a ceramic laminate, which is then sintered. The electroconductive film is formed on each ceramic green sheet, etc.

Abstract: An electric motor, used for moving a seat of a vehicular seat apparatus, is mounted to mounting brackets so as not to produce vibration or unusual sounds. A cylindrical stepped portion projects from a bottom surface of a yoke of the electric motor. A fitting recess, formed in a frame member, is press-fitted over the yoke stepped portion such that the second frame member is checked from rotating relative to a motor armature shaft, but is allowed to move axially. The electric motor, including the second frame member, is disposed between a pair of first and second mounting brackets arranged in an opposed relationship in the axial direction of the electric motor. The electric motor is fixed by tightening screws into threaded holes formed in the frame member from an outer surface of the adjacent mounting bracket so that no gap is left between the frame member and the adjacent mounting bracket.

Abstract: A feeding coupler is shown, formed as part of a brush holder. Feeding terminals are positioned within the feeding coupler rather than being embedded at the time of molding the brush holder using a resin.The feeding coupler is shaped like a cylinder having a closed end and an opening on a side thereof that is in facing relationship with a yoke. The feeding terminals and a retainer for positioning and supporting the feeding terminals are positioned within the opening. The retainer has a holding portion, which is sandwiched between the brush holder and yoke to prevent the retainer from coming off through the opening.

Abstract: Disclosed is an activating catalytic solution for electroless plating which makes possible carrying out successive processes efficiently, without using organic solvent, involving preparation of activating catalytic solution for forming substrate film, formation of a photo-sensitive film by providing the activating catalytic solution, creation of activating catalyst by exposure of specific areas of the photo-sensitive film to light, development by rinsing unexposed portions of the photo-sensitive film, and immersion of the substrate in an electroless plating bath. The activating catalyst can be created with high sensitivity to light at small energy of radiation. The activating catalytic solution preferably contains zinc oxalate, a copper salt, palladium salt such as palladium chloride, and an alkaline solution such as an ammonia water. The activating catalytic solution is used for forming a photo-sensitive film on a substrate to be subjected to electroless plating.

Abstract: A semi-closed type of breathing apparatus includes an air exhaling duct for guiding breathing air exhaled from a mouthpiece to a canister filled with a carbon dioxide remover, and an air inhaling duct for guiding the breathing air, from which carbon dioxide has been removed, to the mouthpiece. The air inhaling duct and the air exhaling duct are designed in a double-duct structure such that the air inhaling duct is surrounded by the air exhaling duct. That is, the ducts are formed in a single hose. Therefore, detachment of the breathing apparatus from a user is easily performed, the overall appearance of the apparatus is not marred, and the entire construction of the apparatus is simplified.

A stepped groove is formed on the bracket inner peripheral surface and positioned between the bearing and the oil seal, with its diameter decreasing in a stepped manner toward the bearing. An oil outlet is also formed on the bracket inner peripheral surface for discharging oil which has penetrated beyond the oil seal. The structure is capable of highly secure prevention of oil penetration into the motor.
