摘要： PROBLEM TO BE SOLVED: To provide a contact forming method for a thin-film structure, which reduces a forming amount of a thin-film conductor when a contact part and a thin-film conductor of the thin-film structure are simultaneously formed, and has little variation in film thickness.
SOLUTION: The thin-film structure is constructed by simultaneously forming a contact part for electrically interconnecting lower and upper conductive layers stacked up and down via an insulating layer, and a thin-film conductor disposed on the lower conductive layer via the insulating layer in a position not overlapping the upper conductive layer. The contact part is made of a material similar to that of the thin-film conductor and formed in such a manner that a linear lower contact brought into contact with the lower conductive layer, but not with the upper conductive layer and a linear upper contact brought into contact with the upper conductive layer but not with the lower conductive layer, are connected adjacently to each other, and a step is formed between the upper surfaces of the lower and upper contacts.

摘要： PROBLEM TO BE SOLVED: To provide a laminated electronic part of a ceramic base having a structure of a mark material not peeling from a chip and to provide a method for manufacturing the same.
SOLUTION: The surface of a mark 3 showing at least one of the direction, a part name and a manufacturing number is covered with a protective layer 1m made of ceramics or a glass. Thus, when the chip is barrel treated while green, the peeling of the mark from the chip is avoided. The protective layer of the mark 3 is formed of a green sheet in a sheet laminating process or is formed by printing. Alternatively, in the case of the printing method, the protective layer is formed by printing paste.

摘要： PROBLEM TO BE SOLVED: To provide a switching power supply comprising an excessive temperature protective circuit operating appropriately even if a control circuit is in a abnormal state. SOLUTION: A switching conversion circuit 2 comprises a switching element 21 being turned on/off by a drive signal S5 supplied from a drive circuit 5 and outputs a voltage being supplied through an input circuit 1 while converting the voltage into a switching output. The switching output is supplied to an output circuit 3 and outputted after being regulated into a specified output. A control circuit 4 supplies a control signal S4 to the drive circuit 5. An excessive temperature protective circuit 6 comprising a temperature detecting section 61 and a switch section 62 is connected with the control electrode of the switching element 21 and interrupts the drive signal S5 through a switch section 22 when the temperature detecting section 61 detects an abnormal temperature of the switching power supply.

摘要： PROBLEM TO BE SOLVED: To obtain a ceramic resonator with high reliability and satisfactory yield in which the damage of an element main body cannot be generated even when a strong impact is received at the time of mounting and inserting this device on a printed circuit board by inclining the edge part of a lead terminal toward the leg part, and fixing the both edge parts of the element main body. SOLUTION: An edge part 1b at the mounting side of an element main body 2 of a lead terminal 1 is bent toward a leg part 1b by bending or integral formation so that the end part 1b can be inclined toward the leg part 1a. The both edges of the element main body 2 are matched to those inclined edge parts 1b, and soldered or fixed with conductive adhesive 13 such as resin adhesive. A cavity part 7 is provided in the surrounding of the neighborhood of the central part of the element main body 2. The leg part 1a of the lead terminal 1 is removed, and this device is covered with insulating resin 4 made of epoxy resin. It is desired that the inclination θ of the edge part 1b of the lead terminal 1 is more than 30 degrees and less than 60 degrees.
