Filed: 1996-10-09
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device which provides sufficient insulating isolation performance even when an insulating isolation width is reduced, in an integrated circuit which isolates elements by a field shield structure.

Title: Current sensor
Inventor: DONARUDO FURANKU BUROTSUKU
IPC: G01R15/14
Filed: 1989-10-17
Abstract: PURPOSE: To detect current that is proportional to input current from current that is induced in a second conductor by providing the second conductor coaxial to a first conductor with an opening and dividing a supply current into a given ratio. CONSTITUTION: A current sensor 8 includes a current divider 10. With the divider. a shunt resistor 12 (R1 ) and a measurement resistor 14 (R2 ) are connected in parallel at points 13 and 15. An input current IIN of a conductor 30 is divided into a current 12 of a measurement resistor 14 with a specific ratio. A core 18 of a current comparator 16 surrounds the measurement resistor 14, becomes a primary coil winding, and supplies a voltage generated at a coil winding 20 to a differential amplifier 24. Its output is applied to one terminal of a compensation coil winding 22 and an output signal IOT is obtained at an output terminal 21.  An alternate magnetic flux in the core 18 can be maintained to be nearly 0 by the comparator 16 and the amplifier 24, thus balancing amperes by the primary coil winding one turn due to the resistor 14 and a secondary coil winding 22 with N turns, thus obtaining the output IOT by scaling the input IIN.

Title: External magnetic field generating apparatus
Inventor: SEKINE TAKEHIKO
IPC: G11B11/10
Filed: 1997-10-01
Abstract: PROBLEM TO BE SOLVED: To suppress bound to shorten a magnetic field inverting time by utilizing generation of an eddy current of a conductive member by providing a driving means with a stopper for allowing a magnet to move within the range from the first position to the second position and inhibiting further movement exceeding the range and also providing a conductive member to the area near the poles of magnet located at the first and second positions. SOLUTION: When no current is flowing to a magnet 1 (during the data reading), the magnet 1 is in the condition that the S pole is nearest to an iron piece 10, while the N pole is nearest to an iron piece 9 (a stopper 6 is in the vertical condition). When a current flows, the magnet 1 rotates until the stopper 6 collides with a base 2 and moves to the first position. In this case, further magnetic field is applied to a magneto-optical-disk M from the magnet 1, resulting in, for example, the data erasable condition. Next, when a current flows in the inverse direction, the magnet 1 is inverted to move to the second position. Here, the stopper 6 elastically collides with the base 2, bounds to generate an eddy current to a conductive plate 20.

When the set temperature T2 slightly higher than the dissolving temperature T1 of the solidified matter 5, the heating is turned OFF and then, the time length t3 is mea sured until the temperature falls down to the temperature T3 set lower than the temper ature T2. Then, the temperature T3 set lower than the temperature T2. Then, the temperature is raised up to the T2 and the heating is turn OFF to measure the time length until the temperature falls down to the level T3. By repeating this operation, complete dissolution is determined when the heating stoppage time reaches the set value t3, for instance. Thus, the complete dissolution can be automatically judged.

Filed: 1988-10-25
Abstract: PURPOSE:To prevent malfunction of a circuit and to reduce current consumption by staggering the rise and fall times of gate inputs of a p-channel MOS transistor(TR) and an n-channel MOS TR so as to prevent overlapping and thereby preventing a through-current from flowing to the output. CONSTITUTION:When a potential at an input terminal 11, that is, at a point A1 rises from a low level to a high level, a potential at an output point C1 of a NOR gate 2 is descended. When an output of a low trip inverter 3 descended, the potential at an output of a NAND gate 1, that is, the potential of a point B1 is descended. Thus, the potential of the point B1 is being descended after the potential at the point C1 is sufficiently descended. An n-channel MOS TR Q2 is turned off at the trailing of the point C1 and a p-channel TR Q1 is first turned on at the rise of the point B1. Then a through-current flowing through the TRs Q1, Q2 is almost interrupted.
