Title: Method for optimally printing with ink ribbon
Inventor: KAWAGUCHI YUJI
IPC: B41J33/54
Filed: 1999-02-24
Abstract: PROBLEM TO BE SOLVED: To reduce a printing cost per one sheet by printing a plurality of rows with the ribbon for one row and then executing a reverse line feed for returning to a printing position of one row in the case of a plurality of row printable data size in a lateral width of one row of the ribbon in a printing range. SOLUTION: In the case that two rows are filled in a width of an ink ribbon of one row, data of two rows are separated into three color data of Y(yellow), M(magenta) and C(cyan) (S15, S16), and a thermal transfer printer prints only Y data of the ribbon aligned in order of the Y, M and C (S17 to S18). In this case, since the ribbon is retained by half, a sheet is line fed and subsequently Y data is printed on second row (S19 to S20). In this case, since a color print is expressed by a combination of colors, to superpose the next color on the first row, the ribbon is returned to a head, and a reverse line feed for returning the sheet by one row is conducted, and cueing of the M ribbon is executed (S22).

Title: Magnetic fluid sensor
Inventor: RAJ KULDIP
IPC: C08L1/02
Filed: 1998-02-10
Abstract: PROBLEM TO BE SOLVED: To shorten response time by providing an airtight housing covered with material nonwetted by a magnetic fluid, a permanent magnet movable in the airtight housing, magnetic fluid rings not sealing space between magnetic poles and the housing, and a magnet position detector. SOLUTION: An axially polarized permanent magnet 3 and a nonmagnetic fluid 7 are put in an airtight housing 2. The permanent magnet 3 floats in the housing 2 due to buoyancy formed by magnetic fluid rings 1, 4 formed at both poles of the magnet 3, and a magnetic fluid. The magnetic fluid rings 1, 4 are held at both ends of the permanent magnet 3 by the magnetic field formed by the permanent magnet 3. It is desirable to mix alcohol and water to use as the fluid 7. The fluid 7 is not therefore mixed with the magnetic fluid existing at the magnetic fluid rings 1, 4, nor generates chemical reaction.

IPC: E02D5/80
Filed: 1993-02-12
Abstract: PURPOSE:To prevent load acted on tension members having different lengths from concentrating it to some of them and provide an anchor having a simple constitution with a high execution efficiency. CONSTITUTION:Tension members 4 having different lengths are divided into a group of tension members by the same length and are arranged in an excavated hole 5 to anchor. An interval between anchoring positions of tension members 4a, b and c is 1.5-3m, and the length of the tension member 4c anchored nearest to the surface of the earth from an anchoring position thereof to the surface of the earth is longer than 6m. Tension is separately made every group of tension members, and tensile force reaching to the limit of allowable design tensile force is provided to the tension members 4 anchored to the deepest position. The allowable design tensile force is normally 60% of fracture load of the tension members 4. With the shortening of the lengths of the tension members 4, the tensile force provided to each group of tension members is gradually decreased. Approximate 10% of fracture load is decreased. In the case of an emergency, when load is increased, the shorter tension members 4b and 4c have extension smaller than that of the longer tension member 4a. Accordingly, the rate of increase of load is such that the shorter one is in excess of the longer one, and the load provided in advance, so that load is not concentrated to the shorter tension member 4c only.

Filed: 1988-03-02
Abstract: PURPOSE:To move a cursor in an intended direction at the time of reverse movement of a mouse by moving the cursor in a direction in a certain angular range, whose center is a stored direction, by an extent corresponding to the extent of movement of the mouse. CONSTITUTION:A mouse 2 having two movement vector detectors is used, and input data from the mouse 2 is reported to a CPU 6 through an input controller 9 as a pair of a movement vector and the detector number each time when the mouse is moved for a certain length. In the normal mode, the mouse movement vector in a mouse coordinate system is converted to a cursor movement vector in a display coordinate system which has the same direction as the mouse movement vector and has a magnitude proportional to that of this vector. In the moving direction limit mode, the cursor movement vector is equalized to a temporary cursor movement vector when the angle formed by the temporary cursor movement vector obtained in the same method as the normal mode and a cursor moving direction limit vector is 90 deg. or narrower. When this angle is wider than 90 deg., a vector which has a direction opposite to that of the temporary cursor movement vector and has the same magnitude as this vector is defined as the cursor movement vector.

Patent JP-H04265802-A (JP)
Title: Displacement detector
Inventor: NIWA HIDEO
IPC: G01B7/00
Filed: 1991-02-20
Abstract: PURPOSE:To detect the displacement of a magnetic shield member electrically and to enhance the freedom in the mounting direction by providing a detecting coil which imparts magnetic flux to both arm parts so that reverse polarities are mutually formed in a U-shaped core, and changing the inductance of the detecting coil by in and out motion of the magnetic shield member. CONSTITUTION:When AC is imparted from an AC power supply 11 to a detecting coil 7, the magnetic flux is generated in the coil 7. The magnetic flux PHI circulates through a linking part 5, an arm part 3, a receiving space 6 and an arm part 4. When a magnetic shield member 8 is located at a part in the receiving space 6, the magnetic flux PHI becomes eddy current and disappears even if the magnetic flux PHI is going to pass through the member 8 between the arm parts 3 and 4. The amount of the magnetic flux is changed in approximately proportion to the size X of a non- overlapping part 15. Therefore, the inductance of the coil 7 is changed in response to the size (y) of the input and output part of the member 8. Thus, the current flowing through the coil 7 is also changed. The voltage signal corresponding to the change is obtained with a detecting means 12. Since the tip sides and both lateral sides of the arm parts 3 and 4 are opened, the freedom in the mounting direction is high, and the design in the mounting direction is made easy.

Abstract: PURPOSE:To provide a motor, in which rotary balance can be kept for a prolonged term by inhibiting the generation of backlash in a device and which can be used for the prolonged term as compared to conventional devices by enabling second adjustment when rotary balance is lost. CONSTITUTION:The diameter of the revolution of a magnet yoke 13 is formed in size larger than a part of the outside diameter of a stator section, and a balance adjusting member 16 is mounted inside the magnet yoke 13. Since the balance adjusting member 16 is installed, the backlash of the member due to the vibrations of a motor is eliminated, thus employing the device for a prolonged term. The balance adjusting member 16 can be exchanged and mounted and dismantled without disassembling the device, thus easily adjusting balance again.
