摘要： PROBLEM TO BE SOLVED: To eliminate an inconvenience caused by irregular magnetic flux distribution, magnetic flux leakage, or inductance leakage, related to a thin transformer used for a power convertor such as a small switching power source and an inverter. SOLUTION: An insulating board 1 is provided with a plurality of slits 5 at a regular interval into which protruding parts 45 of a magnetic body 44 are inserted at a regular interval. On the upper surface of the insulating board 1, a primary-side conductor 21 constituting a primary-side conductor pattern 2 is so provided as to circulate zigzag the slits 5. The primary-side conductor 21 includes eight sections extending in the length direction of the slits 5, with the ends connected with a short primary connection conductor 22 (seven in total) to zigzag fold back, constituting the primary-side conductor pattern 2. On the lower surface of the insulating board 1, a secondary-side conductor 31 constituting a secondary-side conductor pattern 3 is provided in the slits 5. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To enhance a degree of design freedom for inductance and capacitance by reducing mutual interference in the case of manufacturing an inductor/ capacitor composite component. SOLUTION: A 1st electrode layer 21, a dielectric layer (PST layer) 3, and a 2nd electrode layer 22 are formed on a substrate 1 in this order to form a capacitor section, and a flat inductor consisting of a magnetic film 5 and a coil 4 is formed on the capacitor section so as to make the capacitor and the inductor independent of each other in terms of the circuit thereby reducing the mutual interference and enhancing a degree of design freedom of the inductance and the capacitance.

摘要： PROBLEM TO BE SOLVED: To enable ensuring high bonding strength between a control terminal and sealing resin while the external size of a package of a plastic molded type semiconductor device is restrained to be small. SOLUTION: A power element 1 and a control element 2 are mounted by using a lead frame 3, and a heat dissipating metal plate 4 is arranged on the back side of a lead frame. The periphery of the heat dissipating metal plate 4 is collectively sealed with resin 6, and a plastic molded type semiconductor device is constituted. In this case, a lead segment of a control terminal 3d which is connected with the control element 2 through a wire and is led out from a package to the side direction is made a straight shape, and a notched and recessed part 3d-1 is formed in an inner lead part of the control terminal buried in a sealed resin layer, and anchor-bonded with the sealed resin. As a result, bonding strength between the control terminal and the resin is increased, and the control terminal does not simply come out from the package when an external force F is applied.

摘要： PURPOSE:To provide a drive circuit which realizes a sensorless drive system capable of suitably coping with a shortening of a starting time and impossibility of starting a brushless DC motor. CONSTITUTION:A stopping circuit for detecting shortening of an interval of output pulses of an energization signal arithmetic circuit for generating an energization signal at the time of operating and stopping a starting circuit, and an OR circuit for producing an OR of an output of the starting circuit and an output of the arithmetic circuit in each phase as an energization signal to an inverter, are provided thereby to eliminate a zone in which the energization signal does not exist between a starting time and a sensorless operating time. Further, when the start becomes impossible, the stop of the starting circuit is eliminated, the output of the starting circuit again becomes effective to be restarted. When the stopping circuit is composed of a time limiter which inputs one of the outputs of the arithmetic circuit or a plurality of ORs and outputs a pulse having a wide width, the output of the limiter is, when the interval of the input pulses is shortened, continued, and the starting circuit is stopped.

摘要： PURPOSE:To miniaturize the title apparatus and reduce its cost by providing said apparatus with a channel-shaped rail, which is laid after a scale and a pulse signal feeder have been arranged therein, and with a movable element built in said rail. CONSTITUTION:The subject apparatus uses a linear pulse motor for a curtain rail for a domestic room curtain and is equipped with a rail 1 laid on the ceiling side along the moving path of a curtain 2, when said curtain is opened and closed. A motor scale 3 with dentitions at a specified pitch formed in a magnetic plate is laid in the center of the ceiling face within said rail 1 along the lengthwise direction of the rail and input pulse signal feeders 4 are laid in the left and right side faces via insulator 5. On the other hand, the movable element 6 of said linear pulse motor is built in the inner part of the rail 1. Said movable element 6 is composed of a pair of electromagnets consisting of U-shaped cores 6b, in which pole teeth 6a face each other, and exciting coils 6c; a permanent magnet 6d, and a yoke 6e; and is equipped with a traveling roller 7 and collecting brush 8. Thus, an input pulse signal is given to said coils 6c so that the movable element 6 is caused to start stepping motion.

摘要： PURPOSE:To generate uniform and smooth torque by offsetting a pulsating part included in a rotational torque generated between stator and rotor by a pulsating torque generated between a magnetic path member and said rotor. CONSTITUTION:A fixed annular magnetic path member 30 is provided to form a magnetic path parallel to a stator 10 for a rotor side magnetic flux flowing through the magnetic path of a rotor 20 and to cause a reluctance of the former magnetic path to change circumferentially of said rotor side magnetic flux. The number of poles of the change of reluctance of said magnetic path member 30 is selected and the center of said pole is made to deviate circumferentially from the center of the magnetic pole of said stator 10 so that a pulsating part included in a rotational torque generated between the stator 10 and rotor 20 is offset by a pulsating torque generated between the magnetic path member 30 and rotor 20.
