A ceramic assembled board shows an advantageous dividablility of allowing the board to be divided when intended and not allowing it to be divided with ease when unintended. A ceramic substrate shows an excellent degree of dimensional precision and bending strength. A ceramic circuit substrate shows a high dielectric strength. A ceramic assembled board is formed by cutting continuous dividing grooves on one or both of the surfaces of a sintered ceramic board by way of laser machining to produce a large number of circuit substrates and at least one of the continuous grooves has a largest depth section and a smallest depth section with a depth difference Δd of 10 μm ≦Δd≦50 μm. A ceramic substrate is produced by dividing the ceramic assembled board and at least one of its lateral surfaces is a surface formed by dividing the ceramic assembled board along the continuous grooves, the arithmetic mean roughness Ra2 of the machined surfaces of the continuous grooves being smaller than the arithmetic mean roughness Ra1 of the surfaces of broken sections with regard to the arithmetic mean roughness Ra of the lateral surfaces.

To provide a current controller capable of constantly detecting an offset value of a current detection system, the offset value overlapping with a current detection value, in a state of regular operation of a motor to correct the current detection value and capable of current detection with high accuracy and a current offset correction method of the same.A carrier wave peak-trough judging part 10 is provided to discriminating the peak and the trough of a carrier wave. An A/D converted value detected in falling from the peak of the carrier wave is used as a current detection value. An A/D converted value detected in rising from the trough of the carrier wave is used as an offset value in the case that a modulated wave command is larger than a comparison standard value capable of computation by means of a calculation formula. On the basis of the current detection value and the offset value, carried out is an operation of a current detection correction value.

摘要:
A semiconductor device having both high strength and high thermal radiation that is capable of being applied to mounting on automobiles experiencing many thermal cycles, and a manufacturing method thereof are provided. A circuit board 1a for a resin encapsulated semiconductor module device has a configuration where a silicon nitride plate 2 with a thickness of 0.635 mm has copper plates of 1.0 mm and 0.8 mm bonded to both sides thereof via active metal. A copper plate 3a is bonded to the surface side of the silicon nitride plate 2, and a prescribed circuit pattern is formed on the copper plate 3a. Tin-silver-copper cream solder layers 4a and 4b with a thickness of 200 μm are formed at a prescribed location on the circuit pattern 3a on which a semiconductor element 6 is mounted and at a prescribed location of a base plate 1 on which the circuit board 1a is disposed. Nickel particles 5 having a maximum particle size of 100 μm and an average particle size of 70 μm are dispersed in the solder 4a on the base plate 1 of good thermal conductivity. A semiconductor element (chip) 6, the circuit board 1a, and the base plate 1 are disposed on predetermined locations. Thereafter, they are set in a reflow oven (not shown in the drawings) for reflow soldering. After the inside of the reflow oven is replaced by a nitrogen atmosphere, the reflow oven is heated to 280° C. At the time when solder is melted, the inside of the oven is decompressed to 1 Pa, nitrogen is introduced, and the reflow oven is cooled to about room temperature, thereby completing the solder bonding step. After flux is washed, an outer case 7 with an insert-molded outlet terminal 8 is adhered to the base plate 1 and a predetermined connection is conducted via an aluminum bonding wire 9. Then, silicone gel 10 is injected into a package delimited via the base plate 1 and the outer case 7, and the silicone gel 10 is heat-hardened, thereby completing a resin encapsulated semiconductor device A.
摘要:
In an electrostatic atomizing hairdryer, electrostatically atomized mist generated in an electrostatic atomizing unit is effectively scattered into airflow emitted from a main body of the hairdryer so that the mist can be sprayed to hair uniformly and a time necessary for treatment of hair can be shortened. A tank constituting the electrostatic atomizing unit is detachably provided on a portion in the vicinity of an outer periphery of the main body, and an electrode unit for generating the mist is provided in a path of airflow sucked in an inside of the main body so as to be insulated from heat of a heating unit by an adiabator. A mist emitting opening from which the mist is emitted is disposed on a plane substantially the same as and at substantially the center of an air exit opening of the main body. Thereby, the mist emitted from the mist emitting opening is effectively scattered into the airflow emitted from the air exit opening.
