摘要： PURPOSE:To improve the mounting density of hybrid integrated circuit and the mass productivity of coil components by a method wherein a ferrite core is mounted on multiple printed and baked conductors on a ceramic substrate and then the conductors are connected in series by wire bonding process striding over the ferrite. CONSTITUTION:A ferrite core 3 is tacked on a ceramic substrate 1 using a bonding agent 4. Next, gold wires or aluminum wires 5 are connected by wire bonding process after striding over the ferrite core 3 at respective parts A'-B, B'-C of connectors 2 comprising the ceramic substrate 1 printed with an electrode material and then baked. Consequently, a coil component is directly manufactured on the ceramic substrate 1 by winding the conductors A-E around the ferrite core 3 four times. Through these procedures, the mounting density of hybrid integrated circuit can be increased enabling the winding factor on the primary and the secondary sides to be set up easily.

摘要： PURPOSE:To provide the promotion of improvement for efficiency and characteristic, by supplying an input of the switching system stabilizer circuit as the input to the continuous control stabilizer circuit. CONSTITUTION:A DC output, obtained from AC power source through a rectifier circuit B and a smooting circuit C, is fed to a first stabilizer circuit of switching system that controls a ratio of conduction and non-conduction of a control circuit D. An output of the first stabilizer circuit is fed as an input to a second stabilizer circuit of continuous control system that varies an impedance of control circuit J. Subsequently, with an output of the second stabilizer circuit made a reference voltage of the first stabilizer circuit, by controlling a ratio of conduction and non- conduction of the first stabilizer circuit in accordance with a deviation obtained from a comparison with the output of the first stabilizer circuit, a DC stabilized power source will be obtained with good efficiency and characteristic.

摘要： PURPOSE:To reduce power consumption and reduce a noise generated by a servomechanism by making a fine/rough change of an adjustment of a lens position according to whether a subject is light or dark. CONSTITUTION:The automatic focus adjusting device of a camera is equipped with an automatic focus adjusting circuit 2 which outputs output signals O1 and O2 when the difference between a distance measurement signal VM corresponding to the distance to the subject A and a lens position signal VL corresponding to the lens position of the camera and the servomechanism 3 which corrects the lens position of the camera with the output signals O1 and O2 from the circuit 2, and the specific difference value between the distance measurement signal VM and lens position signal VL at which the output signals O1 and O2 are sent out is varied according to the brightness of the subject A. Consequently, this device makes a rough adjustment of the lens position when the subject is bright to save electric power and also reduces a noise generated by the mechanism 3; when the subject is dark, the adjustment of the lens position is made finely, so a sharp image is obtained.

摘要： PURPOSE:To prevent the breakdown of package in the thermal impact test due to the difference of thermal expansion coefficients of a resin and a metal plate by sealing a hybrid integrated circuit provided between the pair of metal plates located in parallel with the resin. CONSTITUTION:Metal plates 3 and 4 are located in parallel and a hybrid integrated circuit provided between them is sealed by a resin 5. Thereby, the internal stress due to a slight difference of thermal expansion coefficients of the resin and metal plate is concentrated to the bonding area of the resin and metal plate without resulting in separation. Moreover, such internal stress is cancelled by the opposing metal plates, thus drastically improving the thermal impact resistance. In addition, the transfer mold method can be employed, followed by improvement in the mass-productivity, and other characteristics such as the pressure-cooker resistance, chemical resistance and oil resistance are as much enhanced as compared with a current hollow package.

摘要： PURPOSE:To eliminate the influence of errors of break trenches and through holes, avoid the concentration of thermal stress, and prevent the cracks of ceramic substrate, by arranging circular through holes at crossing points of the break trenches of the ceramic substrate provided with the break trenches. CONSTITUTION:Circular through holes 3 are arranged at crossing points of break trenches of a ceramic substrate 2. Even if the trenches 1 and the circular holes 3 have errors, edges of sharp angle do not generate. The connection point of the break trench 1 and the through hole 3 is right angle, and concentration of thermal stress to the brake trench at the time of firing is eliminated.

摘要： PURPOSE:To minimize a noise generated in distance measuring operation and power consumption by adjusting time intervals of distance measurement and lens position correction according to the motion of a subject. CONSTITUTION:The automatic focus adjusting device of a camera is equipped with a distance measurement part 10 which outputs a distance measurement signal corresponding to the distance to the subject A at time intervals, a comparing circuit 4 which outputs a signal corresponding to the difference between the distance measurement signal H from the distance measurement part 10 and a lens position signal I corresponding to the lens position of the camera, and a driving circuit 6 which corrects the lens position according to the signal from the circuit 4. Then, this device detects whether the subject A moves fast or slow from whether the operation time of the circuit 6 is long or short. Consequently, when the subject A moves fast, the adjusted period is short to increase the frequency of distance measurement, and when the motion is slow, on the other hand, the distance measurement period becomes longer to decrease the frequency of distance measurement.
