Title: Overcurrent relay
IPC: H02H3/08
Filed: 1978-02-27
Abstract: PURPOSE:To simplify the constitution of relay by omitting reactor by the method in which auxiliary relay is energized by the impedance drop voltage of relay coil. CONSTITUTION:The overcurrent relay consists of the relay coil 54 to drive the contact 55, the auxiliary relay coil 57 to drive the contacts 58 and 59, and the tripping coil 2 into which the secondary current of current transformer is introduced on energization of the coil 57. When a short-circuit fault occurred, the current transformer secondary side current I2, corresponding to short-circuit current, flows in the coil 54 and the contact 59 and the contact 55 is closed. At this time, the impedance drop voltage VCO due to I2 is produced at the both ends of the coil 54, and the VCO is then applied to the coil 57 and the contact 58 is closed. Then, I2 dividedly into the coils 54 and 57. In this case, since the auxiliary realy is not fed back even if the VCO is lowered, the contact 58 is closed and the contact 59 is opened. Accordingly, the I2 flows in the relay coil 54 and the tripping coil 2 and the breaker 1 is operated.

Title: Piezoelectric actuator
Inventor: ADACHI HIDEO
IPC: H01L41/083
Filed: 1986-02-04
Abstract: PURPOSE:To ensure the working of a piezoelectric actuator with high accuracy and a long lifetime and with no hysteresis nor creep phenomenon without receiving the effects of electric, magnetic and optical noises, by setting an optical displacement sensor into the hollow part of a cylindrical piezoelectric lamination matter. CONSTITUTION:A cylindrical piezoelectric lamination matter is formed by laminating many sheets (n sheets) of piezoelectric element 33 produced by bonding an electrode plate to an annular washer type PZT piezoelectric ceramic plate. A housing 32 set on a pedestal 31 stores said cylindrical lamination matter. The electrodes of the lamination matter are connected in parallel every 2nd layer by means of a connection 34 and connected to a high pressure resistance connector 35. Then the drive voltage V is impressed to the elements 3 via the connector 35. Thus a displacement amount shown by DELTAX=n.d33.V is produced at the displacement end (upper end part in the figure). Here the displacement amount DELTAX is not affected directly by the thickness of a single layer of the element 33. Thus it is desirable to reduce the thickness (t) as less as possible and also to decrease the total length of the lamination matter.

IPC: H03F9/00
Filed: 1987-02-04
Abstract: PURPOSE:To suppress the loss of a saturable magnetic core and its temperature rise even when the frequency of an AC power source is made high by arranging a magnetic field impressing means which reduces the saturated magnetic flux of the saturable magnetic core according to the intensity of a magnetic field by the impression of magnetic field to the saturable magnetic core in a constant direction from outside. CONSTITUTION:A magnet body 21 as the magnetic field impressing means is arranged facing the outer peripheral part of the saturable magnetic core 20 made of a troidal core. The magnet body 21 impresses the magnetic field to the saturable magnetic core 20 in the constant direction from outside to reduce the positive and negative pieces of saturated magnetic flux of the saturable magnetic core according to the intensity of the magnetic field. The saturable magnetic core 20 produces magnetic flux of density corresponding to the intensity of the external magnetic field with the magnetic field impressed in the constant direction by the magnetic field impressing means 21. The saturable magnetic core 20 reaches the saturated magnetic flux partially with a magnetic flux quantity which is less by the magnetic flux of this external magnetic field. Consequently, the saturated magnetic flux of this saturable magnetic core is reduced equivalently by the magnetic flux of the external magnetic field and its loss and temperature rise are suppressed even when the frequency of the AC power source is made high.

Title: Mechanical parking device
Inventor: FUJIKAWA ATSUSHI
IPC: B65G1/04
Filed: 1998-02-04
Abstract: PROBLEM TO BE SOLVED: To surely transmit the power between gears approaching to/separating from each other. SOLUTION: When a power transmission gear 26 and a driven gear 29 are brought into contact with each other, the positions of mutual rotary shafts 39, 31 are deviated in the direction crossing at right angles with their separating/ approaching directions. The contact CP of the two gears 26, 29 thus becomes a position deviated from the tip face in the mutual separating/approaching direction. The abutting force in the contact CP acts in the direction for crossing at right angles with the tangent line of the two gears 26, 29. This abutting force generates a bending moment with the fulcrum 37 of a bracket 36 as the center. Elastic energy by torsion is stored in the fulcrum 37 of the bracket 36. The elastic energy is used as a force (pre-load) for pushing the driven gear 29 toward the power transmission gear 26. The elastic energy is used as the pre-load between the two gears so as to improve the follow-up performance of the two gears 26, 29 in the contact CP.

Abstract: PURPOSE:To improve the stability of both color and vertical reference signals, by using a frequency divider to decrease the number of crystal oscillators by one, and synchronizing between the color and vertical reference signals. CONSTITUTION:The information recorded on a magnetic tape 1 is fed to a luminance signal processing circuit 3 and a color signal processing circuit 4 from a detector 2 via a rotary transformer. Then the output of a reference oscillator 6 is supplied to a frequency divider 15. At the same time, the synchronism is obtained between a division switch device 16 and an oscillator switch device of the oscillator 6. Thus a dividing ratio corresponding to the frequency of a color reference signal is obtained. As a result, the same vertical frequency is obtained with both NTSC and 4.43NTSC systems. Thus the synchronism is obtained between the color and vertical reference signals.
