Title: Digital driver circuit
Inventor: TANAKA MINORU
IPC: H02P29/00
Filed: 1991-12-05
Abstract: PURPOSE:To reduce the motor speed by controlling an overcurrent with an overcurrent control means provided in a digital driver circuit, in which an overcurrent detected signal is generated, and a digital control signal is changed on the basis of the magnitude of the overcurrent when the revolution rate is sharply diminished. CONSTITUTION:A digital driver circuit comprises a comparator 3 for generating a PWM signal by comparing via an overcurrent control means 5 an output provided from a counter 2, which works on the basis of a clock signal 1, with a digital control signal 6 generated from a microcomputer, and a driving means 7 for driving a motor in response to the PWM signal. In this case, an overcurrent detected signal is not sent to the microcomputer, but the overcurrent control means 5 changes the digital control signal 6, and the comparator 3 generates the PWM signal so as to reduce the revolutions of the motor. Then, the overcurrent can be prevented. Consequently, the overcurrent control can be performed surely and instantaneously regardless of the state of the microcomputer.

IPC: G01D5/245
Filed: 1994-12-26
Abstract: PURPOSE: To provide an encoder diagnostic device in which an absolute value encoder or incremental encoder can be easily diagnosed. CONSTITUTION: The absolute value data transmitted from an absolute value encoder 12 when a power source is OFF is stored in a nonvolatile memory 25. When the power source is then ON, the above absolute value data stored in the nonvolatile memory 25 is compared with the absolute valve data transmitted from the absolute value encoder at that time, and when the difference is out of a predetermined allowable range, an alarm is displayed on an indicator 26. The data stored in the nonvolatile memory 25 may be the count value stored in an INC counter 23. In operation, the absolute value data provided from the absolute value encoder 12 is compared with the count value of the INC counter 23 when the rotating speed of a motor 6 is less than a fixed value, and the alarm is displayed on the indicator 26 when the different is out of the predetermined allowable range.

Abstract: PURPOSE:To protect a toner sensor from magnetic field by providing the toner sensor so that it may be covered from the magnetic roller side of a developing device and preventing the effect of the magnetic field caused by two magnetic rollers on the toner sensor. CONSTITUTION:When the N pole 7b of the magnetic roller 5 and the S pole 13a of the magnetic roller 11 approach to each other, the line of magnetic force M which turns from the magnetic roller 5 of a sub developing device 2 to the magnetic roller 11 of a main developing device 3 is generated so as to extend over the toner sensor 15. However, the line of magnetic force M to the toner sensor 15 is conducted inside 'Permalloy(R)' 30 by forming a space in which the line of magnetic force easily flows by the 'Permalloy(R)' 30, then it is branched to the lines of magnetic force M1 and M2. Thus, the line of magnetic force M is prevented from passing in the toner sensor 5.

Title: Method and device for cooling seam part of steel tube
Inventor: TANAKA NOBUKI
IPC: B21C37/08
Filed: 1997-11-25
Abstract: PROBLEM TO BE SOLVED: To provide a hot solid phase pressure-welding method unnecessary for bead cutting and capable of manufacturing a steel tube excellent in quality and surface condition by continuously pressing a solid refrigerant against the seam part of the steel tube before stretch-reduction after butt welding. SOLUTION: A plate-like solid refrigerant 4 is continuously pressed on an inlet side of a stretch-reduction rolling mill 3 against a seam part 10 of a steel tube 1 manufactured through the butt-welding by a squeeze roll 2. Because the solid refrigerant 4 is directly pressed against the seam part 10 for cooling, only the seam party 10 can be cooled without any accelerated cooling of a base material part, and the uneven heat of the seam part 10 can be remarkably and efficiently removed. When the seam part 10 is located on an upper part of the steel tube 1, and the molten stuff flows down to the base material part when the melting solid refrigerant 4 such as ice is pressed against, and the cooling of the base material part is promoted, air is ejected around a contact part with the seam part 10 of the solid refrigerant 4 to blow off the molten stuff.

Title: Ink supplying mechanism for printer
Inventor: KUDO YOSHIHIKO
IPC: B41L13/18
Filed: 1998-11-13
Abstract: PROBLEM TO BE SOLVED: To enhance the degree of freedoms of disposition layout of ink pipes by providing a supply roller near a doctor roller and supplying an ink to an outer periphery of a supply roller. SOLUTION: An ink is supplied to a doctor roller 3 for forming an ink reservoir T to an ink roller 2 brought into contact with an inner periphery of a plate cylinder 1 through a supply roller 4. Thus, since a discharge port 9 may be disposed at any position near an outer periphery of the roller 4, the degree of freedoms of disposing layout of ink pipes 6 to 8 is enhanced. Since the ink supplied from the port 9 into the roller 3 is spread axially in the case of transferring from the roller 4 to the roller 3, an effect of shortening a time of taking for the ink to sufficiently spread in an ink reservoir T is incorporated as well.

Abstract: PROBLEM TO BE SOLVED: To provide a magnetic resonance imaging method and a magnetic resonance imaging apparatus. SOLUTION: Diffusion sensitivity gradients 54 and 56 and reading gradients 66 and 68 are induced into a slice or slab selected along each of a pair of vertical shafts GX and GY. An operation sensitivity gradient pulse makes an excited magnetic resonance sensitive with respect to diffusion in the previously selected direction of diffusion vertical to the selected direction of the reading gradient. The diffusion sensitivity gradients are turned by sin(θ+π/2) and cos(θ+π/2) and the reading gradients by sinθ and cosθ to generate a plurality of angularly displaced data lines. The direction of the diffusion sensitivity is vertical to the direction of reading in each of the data line angularly displaced. The phase of each of the data lines is determined 90 and shifted 94 to compensate for linear movement.  Data values in the data lines are shifted 86 so that the size of the peak of the data line is centered at a previously selected position to compensate for movement of a higher order. The set of the data lines angularly incremented is reconstructed 96 in an image display 98.
