Abstract: PURPOSE: To simultaneously control the input voltage and the load current change, by providing a control and controlled winding, wound on at least one core leg of more than two independent magnetic cores that constitute a closed magnetic circuit, and by providing an input winding, wound on stepping across said independent magnetic core legs.  
     CONSTITUTION: When a control current is not made flowing in a control winding 12, which is wound on the center leg 9a of a closed circuit magnetic core 9, for instance, a difference voltage of two pairs of controlled windings 13 and 16, 14 and 15 is fed to the load from a terminal 19, 20, with a control current made flowing in the control winding 12 from a terminal 21. And a magnetic  resistance of the closed circuit magnetic core 9 relatively increases higher than a magnetic resistance of a closed circuit magnetic core 10, 11, with an interlinking flux in the controlled winding 13, 16 increasing and a generated voltage in the controlled winding 14, 15 of the closed circuit magnetic core 9 decreasing, and a generated voltage in the controlled winding 13, 16 increases. Accordingly, the load voltage is regulated by a flow of the control current in the control winding 12. Of the values of a voltage drop, generated in the controlled windings 13 to 16 by the load current, a component caused by a magnetic induction, with by a resistance excepted, is controlled by the control current.

Title: Speed controller
Inventor: INADA HIROSHI
IPC: G05D3/12
Filed: 1988-02-09
Abstract: PURPOSE:To attain the accurate follow-up control of the motor speed to a reference level at deceleration even with the speed control of a comparatively low band by performing the integration of the speed error signal synchronously with the position of a movable member for each movement and positioning of the movable member and adding the integrated value to the motor driving circuit. CONSTITUTION:A reference speed signal generating circuit 1 produces a reference speed signal in response to the distance between the present position of a movable member 4 and a target position where the member is positioned with movement. Then the circuit 1 forms an ordinary speed control system together with a differential arithmetic circuit 7 which produces a speed error signal, etc. The speed error signal showing the difference between the reference speed and the motor speed is calculated for execution of a normal speed control action to drive a motor 3. At the same time, the speed error signal showing the difference between the reference and motor speeds at deceleration for each access action synchronously with the position of the motor 3. This integration signal 9 is applied to a power amplifier 2 which drives the motor 3 synchronously with the position of the motor 3. Thus it is possible to ensure the follow-up of the motor speed to the reference speed having a large deceleration degree with high accuracy even with the speed control having a comparatively low control band.

IPC: H05K3/18
Filed: 1996-01-24
Abstract: PROBLEM TO BE SOLVED: To provide a printed wiring board whose insulating property between conductors is enhanced and whose reliability is increased by a method in which the lower part of a plated resist layer is formed to be wider than the upper part. SOLUTION: A dry film is laminated on an insulating board 1. After its lamination, a negative film is placed, ultraviolet rays are irradiated at 200mj/cm<2> , and the board is exposed. After its developing operation, the board is dried, ultraviolet rays are irradiated additionally at 1500mj/cm<2> , photosensitive layers are hardened, and plated resist layers 3 are formed. In the plated resist layers 3, the width of upper parts 4 is at 100μm, the width of lower parts 5 is by about 3 to 4μm wider than that one one side, and the parts are formed at an interval of 100μm. Then, after the plated resist layers 3 have been formed, adhesive layers 2 are treated so as to be roughened, an electroless copper plating treatment is then executed, and conductors 6 are formed.  In this manner, since every lower part 5 of the plated resist layers 3 is formed to be wider than every upper part 4, it is possible to obtain a printed-wiring board whose insulating property between the conductors can be enhanced and whose reliability is high.

Title: Ultrasonic vibrator, manufacture thereof and ultrasonic cleaning method
Inventor: SHIBANO YOSHIHIDE
IPC: H04R1/44
Filed: 1994-02-28
Abstract: PURPOSE:To efficiently and uniformly clean a work by emitting ultrasonic waves from both surfaces of a plate-like ultrasonic vibrator. CONSTITUTION:This plate-like ultrasonic vibrator 1 generates the ultrasonic frequency of 0.8-2.6MHz so as to clean the delicate work such as silicon wafer or the like. Then, a lead wire 6 is connected to the end part of the electrode 2b of a piezoelectric element 2 and a protective member 5 is provided around the outer periphery of the element 2. Further, an insulation layer 3 and a vibrator 4 are press-fixed to the surface of the element 2 and the member 5 by evacuation, the insulation layer 3 is fused and the outer periphery of the vibrator 4 is joined together. At the time, in the case of <=0.8MHz, impact force at the time of radiating the ultrasonic waves is too strong and the delicate work is damaged. Also, in the case of >=2.6MHz, the impact force is too weak and a sufficient cleaning effect is not obtained. Then, since tight adhesion is performed without air remaining inside the vibrator 1, even when heat is generated in the operation of the vibrator 1, no air remains inside and thus, the damage of the vibrator 1 due to air expansion is prevented.

IPC: H02M3/28
Filed: 1993-01-26
Abstract: PURPOSE:To prevent the damage of a switching element by the saturation of the magnetic core of a transformer and overcurrent by providing a function, in which a control circuit for the switching element can turn the switching element on/off reliably during one cycle period. CONSTITUTION:When a load 27 is made extremely smaller than the sum of the output power of a DC-DC converter 29 and another power supply 29', voltage higher than no-load output voltage is applied to the output terminals 23, 25 of the DC-DC converter 29 from the power supply 29', and a current is made to flow through the DC-DC converter 29. Consequently, an error amplifier 31 outputs a signal in the direction that the oscillation of an FET 5 for switching is stopped, but the value of an output error signal is limited at a set value lower than the peak value of the triangular waves of a triangular-wave generating circuit 41. As a result, a comparator 39 outputs a minimum ON-pulse in each cycle, and the FET 5 conducts switching reliably in each cycle in minimum ON-pulse width determine at clamping voltage. Accordingly, the saturation of the magnetic core of a transformer and the damage of a switching element can be prevented.

Abstract: PURPOSE:To analyze syntax only once by setting whether or not a word constitutes idiomatic expression by using the substantives as a key word before the syntax analysis. CONSTITUTION:It is decided whether a word which becomes the substantives of the idiomatic expression is present in an inputted document or not by referring to a dictionary memory 13. When the word which becomes the substantives is present, it is decided whether or not a word which coexists with said word is present by referring to an idiomatic expression control storage means 14 and when so, it is decided whether or not the word satisfies the grammatical rule and only when the rule is satisfied, words are processed as a word string which constitutes the idiomatic expression. Thus the substantives are used as the key word to recognize the idiomatic expression before the syntax analysis, so the syntax analysis needs to be performed only once and idiomatic expressions which can be handled is increased in the number of kinds.
