Inventor: KITAMOTO AYAKO
IPC: G11C11/419
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To shorten the transition time of output signal, to increase the operation speed even when the source voltage is reduced, to reduce the power consumption, and to prevent fluctuation in operation speed due to threshold value fluctuation, by providing an amplitude suppression circuit in an amplifier circuit of a small amplitude complementary signal and suppressing the output signal to have a small amplitude. SOLUTION: A current sense amplifier 38 amplifies small amplitude input signals IN1, IN2 in a complementary relation inputted through signal lines 3, 4 to send them to a differential amplifier 39 as the output signals S1, S2 in the complementary relation through output nodes 40, 41. For example, when the voltage of the input signal IN2 is larger than the voltage of the input signal IN1, the output signal S1 increases its voltage to be at an H level. At this time, a current flowing through a pMOS transistor 42 becomes small to suppress that the voltage of the output signal S1 rises large. Thus, a signal voltage inputted to the differential amplifier 39 is suppressed within the range of normal operation.

Title: Permanent-magnet brushless motor
Inventor: MASUZAWA MASAHIRO
IPC: H02P6/15
Filed: 1997-05-26
Abstract: PROBLEM TO BE SOLVED: To make a permanent-magnet brushless motor usable at a high conversion efficiency with strong torque to a large number of revolutions by imparting a relative rotational force to a second field magnet from the moving-side shaft of a governor when the governor is moved along the guide of a fixed member fixed to the rotating shaft of a rotor by a centrifugal force as the number of revolutions of the rotor increases. SOLUTION: Since magnetic fluxes generated form both first and second field magnets 31 and 32 are efficiently introduced to the magnetic poles 11 of a stator and interlinked with field windings 12, the magnetic fluxes leaking to the surrounding structure of a brushless motor are suppressed smaller and the occurrence of such a loss as the eddy current loss, etc., in the surrounding structure can be avoided. In addition, the phase of the resultant magnetic pole of the first and second magnets 31 and 32 against the magnetic pole of the magnet 31 changes as a rotor 2 rotates. For a brushless DC motor, the maximum torque can be obtained by making the center of the conducting period of a winding for generating field magnetic field coincident with the N-S switching point of the field magnetic poles, theoretically.

Title: Power failure detecting circuit
Inventor: IKEDA TOSHIHIRO
IPC: G01R19/165
Filed: 1989-05-29
Abstract: PURPOSE:To prevent erroneous operation at the time of noise or increase/ decrease voltage by taking the output of a converter through two sets of halfwave rectifiers and generating a pulse at a constant cycle. CONSTITUTION:A power failure detecting circuit is constituted of halfwave rectifiers 1, 2, the photocouplers 3, 4 respectively operated by the currents respectively rectified by both of them, the comparators 5, 6 respectively connected to both photocouplers and the exclusive OR 7 connected to the output of both comparators. When AC voltage is supplied, said voltage is subjected to halfwave rectification on the single side thereof by the rectifier and converted to voltage capable of being processed by the photocoupler 3 by the current thereof and a waveform is stamped on the basis of a predetermined threshold value by the comparator 5. The series of the rectifier 2 is also same and the non- coincidence of the outputs of the comparators 5, 6 is taken by the exclusive OR 7 to output a constant cycle pulse. Since the output voltages of the rectifiers 1, 2 are not generated at the time of the generation of power failure, no pulse is generated and, therefore, power failure is judged by the processing circuit of the next stage. By this method, power failure can be stably detected with good accuracy.

Abstract: PURPOSE:To make installability for a moving shoe ever so better, by installing a mechanism lifting the rear end side of a lid, and making a front end of the lid flush with a roof top face at the time of longitudinal movement of the moving shoe. CONSTITUTION:When a cable is driven from the fully closed state and a moving shoe 63 is moved rearward, a guide pin 59 is moved to a tilt-down guide part 61d, and with this movement, the rear end side of a lid 9 comes into such a tilt-down state as going down from an outer panel 5. At the time of this tilt- down, an engaging pin 35 is rotated, making a front arm 27 of a lifting arm 23 go down slightly. With this down movement, a front end 9a of the lid 9 comes to be almost flush with a roof top face 5a in consequence. Therefore, since the front end 9a of the lid 9 can be trued up by longitudinal movement of one moving shoe 63, it gets off with only one moving shoe, thus its assembly comes easy.
