Title: Motor
Inventor: MATSUOKA KAORU
IPC: H02K21/24
Filed: 1988-05-20
Abstract: PURPOSE:To obtain a thin and highly efficient motor having low torque loss due to iron loss by filling magnetic fluid in the hollow section of a stator flat board. CONSTITUTION:A hollow section 22a is formed in a section of a stator flat board 22 facing with a permanent magnet 5 and magnetic fluid 23 is filled therein. When power is fed to the stator winding 8 of a motor 20, a rotor 21 rotates according to Fleming's rule. Since the electrical resistance of the magnetic fluid 23 filled in the stator flat board 22 constituting a magnetic circuit together with the permanent magnet 5 is set considerably higher than that of the stator board in a conventional motor, eddy current scarcely flows in the stator flat board 22 even upon interlinkage of AC flux with the magnetic fluid 23. Consequently, torque loss due to eddy current can be eliminated and torque loss due to movement of the fluid magnetic fluid 23 caused through rotation of the permanent magnet 5 is quite low when compared with torque loss due to conventional iron loss because the magnetic material moves in the fluid.

Title: Drive coupling device for four wheel drive
Inventor: AKAI SETSUICHI
IPC: F16D43/284
Filed: 1994-06-07
Abstract: PURPOSE:To improve break-loose capability in an off-road by connecting a first and a second rotary shafts, which respectively transmit driving force to the front and rear wheels, through a vane pump which delivers oil in an amount in accordance with the difference of rotating speed of these rotary shafts. CONSTITUTION:When a difference in roating speed is generated between an input shaft 24 and a front wheel output shaft 25 of a drive coupling device 23 for a four wheel drive to which driving force of a rear wheel output shaft connected to an engine through a speed change gear is transmitted, a rotor 26 makes a relative rotation with respect to a cam ring 27 and operating fluid in respective oil chambers 28 is pressurized by a vane 30. The pressurized operating oil flows from a delivery side chamber to a suction side chamber through an orifice of the vane 30 and is subject to resistance when it passes through the orifice. Because this passage resistance works in the direction for preventing the relative rotaion of the rotor 26 with respect to the cam ring 27, the difference of rotating speed between the rotor 26 and the cam ring 27 is reduced. In other words, driving force from the engine is distributed to the front wheel side and the rear wheel side, thereby a four wheel drive condition constantly rotating at an approximately equal speed is obtainable.

IPC: B41J2/52
Filed: 1981-08-13
Abstract: PURPOSE:To permit the clear manifestation of low density of tones by a method in which a threshold value is set for signals to be supplied to a printer, the signals below the threshold value ae formed as first control signal whose pulse width is modulated, and the signals above the threshold value are formed as second control signal whose pulse width is modulated. CONSTITUTION:An image element row to sweep lasers is divided into the groups [I]and[II]. The divided image element row[I]represents concentrations by a pulse width-modulated signal[I]M corresponding to the image signal from white to intermediate concentration[threshold value (or level) Vth of image signal S], and also the divided image element row[II]represents density by a pulse width-modulated signal[II]M corresponding to the image signal from the threshold value Vth of intermediate density to black level. By this, in spite of the fact that the coloring area 2a of second image representing bright density next to colorless area can be made into an area colored by sufficient color developing energy, its ratio to the area 2b of the second image element becomes small. Thus, the manifestation of bright density is made possible and printing with stable and bright density can be attained.

Abstract: PURPOSE:To enable the utilization of the dynamic range of an amplifier to the utmost by adjusting an offset voltage of the amplifier based on the output of the amplifier to amplify the output of a magnetoresistance effect element. CONSTITUTION:A constant current circuit 601 supplies a specified current to a magnetic head 600 comprising a magnetoresistance effect element based on the output 2 of a D/A converter 604. An amplifier 602 amplifies the output signal of the magnetic head 600. The amplifier 602 changes the offset voltage based on the output 1 of the D/A converter 604. A comparator 603 converts the output signal of the amplifier 602 to a pulse signal. A control section 606 is so arranged to observe the output signal of the amplifier 602 through an A/D converter 605. Then, when the offset voltage of the amplifier 602 is larger than a prescribed value, the output voltage 1 of the converter 604 is raised and when it is smaller than the prescribed value, the output voltage 1 is lowered. Thus, the offset voltage is adjusted to a set value that allows the utilization of a dynamic range to the utmost.
