IPC: B41J2/41
Filed: 1990-08-17
Abstract: PURPOSE:To suppress noise by providing the rising and falling of drive voltage with a predetermined inclination at the time of turn ON/OFF of a high voltage power supply. CONSTITUTION:Assuming the resistance of a resistor 6 is RIN, the capacitance of a capacitor 9 is CFF, ON/OFF control input signal VIN is a step signal of VINV, reference voltage VREF is VREFV and a charger load 5 is CFF, the waveform VD of drive voltage varies with an inclination of (VREF-VIN)/CF.RIN upon transition of the ON/OFF control input signal V from H to L level whereas varies with an inclination of -(VIN-VREF)/CF.RIN upon transion from L to H level. At that time, the drive voltage VD and drive current ID vary as shown on the drawing. Consequently, impulse current can be eliminated at the time of charger driving resulting in suppression of noise.

Title: Method of measuring inclination angle of camera
Inventor: KOU SHISEN
IPC: G01B21/00
Filed: 1992-07-22
Abstract: PURPOSE:To measure reliably the inclination angle in the horizontal direction and the vertical direction of a camera by a method wherein the inclination of the camera is computed on the basis of the relationship between the position in a screen coordinate system of an object and the three-dimensional coordinates of a world coordinate system. CONSTITUTION:In this method, three-dimensional coordinates of a specific object in a world coordinate system are found in advance, and the object is taken into by a camera. the position in a screen coordinate system of the object is specified, and the inclination angle of the camera in a relationship with the three-dimensional coordinates in the world coordinate system is detected. A plane OXZ is the screen coordinate system, the object which has been taken into from a lens in the camera forms an image on the plane PXZ. For example, when the camera is inclined in the horizontal direction and the vertical direction and not inclined in the rotation direction of the central axis (lens axis) of the camera, the inclination angle PHI in the vertical direction of the camera is the difference between the Y'' axis of a camera coordinate system and the Z' axis of a lens coordinate system, and the inclination angle theta in the horizontal direction is expressed as the difference between the Y-axis of a world coordinate system and the Y'' axis of the camera coordinate system.

Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To provide a driving means for suppressing the generation of oscillating current during the period of time of steering wheel-return in a motor control circuit of an electric power steering device using an H bridge circuit. SOLUTION: FET 1 and FET 2 are concurrently and in dependently driven with a duty ratio D1 and a larger (long in time) duty ratio D2 than the duty ratio D1 respectively. Motor-current I is presented by the following equation containing the duty ratios D1, D2. D2 is defined as the linear function of D1:D2= a.D1+b (a, b are constants). When a, b are determined based on the driving condition, the motor-current I is represented by the following equation. With the relationship between the motor-current I and the duty ratio D1, discontinuous parts are eliminated even in the area where the motor-angular velocity (ω) is smaller than motor-angular velocity (ωret) during the period of time of steering wheel-return, and thereby the generation of noise due to oscillating current can be suppressed. I=Vb/R 1-(KTωret/γVb)}.D1-KT/R(ωret-ω).

Title: Paper discharge switching device
Inventor: HOSOKAWA HIROSHI
IPC: G03G15/00
Filed: 1990-08-17
Abstract: PURPOSE:To push out the recording paper rear end remaining on a paper discharge roller each time switching is performed by disposing and forming the tip of a change-over guide in such a way and shape as to scrape slidingly on the paper discharge roller at the time of switching the guide into the upper paper discharge state. CONSTITUTION:A change-over guide 22 is switched into the chain-line upper paper discharge state and the continuous-line lower paper discharge state. The tip of the guide 22 is brought into sliding contact with a paper discharge roller 21 at the time of switching into the upper paper discharge state. Recording paper in the lower paper discharge state loses carrier force when it comes out of the nip of the paper discharge rollers 20, 21, so that its rear end part remains on the paper discharge roller 21. However, the guide 22 is switched into the upper paper discharge state sheet by sheet in the lower paper discharge state, so that the tip of the guide 22 pushes out the recording paper rear end placed on the paper discharge roller 21. The paper discharge state can be thus improved in a simple way.

Title: Optical star network type communication system
Inventor: MATSUDA MASAHIRO
IPC: H04B10/27
Filed: 1988-08-30
Abstract: PURPOSE:To use the transmission line with high efficiency by providing a buffer capable of storing communication information tentatively when communication information is in congestion with communication controllers. CONSTITUTION:A switch control circuit 21A-5 of a communication controller 2 switches a matrix switch section 22 at first so that the communication information from an incoming line starting the communication at first can be outputted from a required outgoing line. However, while the initial communication information is being outputted through the outgoing line, when other communication information is received through other incoming line, the circuit 21A-5 switches the matrix switch section 22 so that the communication information received through the other incoming line is supplied to a buffer 24. On the other hand, when the outgoing line is idle, the matrix switch section 22 is changed over so that the communication information stored in the buffer 24 is outputted through the outgoing line. Thus, the transmission line is used with high operating efficiency.

IPC: H01F7/20
Filed: 1990-08-20
Abstract: PURPOSE: To reduce the unevenness of the magnetic fields generated from one ore more pairs of ferromagnetic compensating rings by coaxially positioning the rings around the axis of the center hole of a magnet and symmetrically, with respect to the central point of the axis within the length range of the hole. CONSTITUTION: One or more pairs of ferromagnetic compensation rings 52 are coaxially positioned around an axis 36 of the center hole of a magnet, and each ring is symmetrically arranged with respect to a central point 44 of the axis 36. The size of a coil 40 and the sizes of rings 2, namely, the positions of the rings 52 in the radial and axial directions are selected so as to reduce the unevenness of the magnetic fields generated from the rings. Then the contribution of the magnetic fields at a target magnetic flux point produced from the actual magnetic fluxes of a shield and the rings 52 is decided. When the evenness of the magnetic field does not reach a desired level, only the size of the coil 40 is repeatedly adjusted until the desired evenness is obtained, while the contribution from the magnetic fields generated from the shield and rings is maintained constant. Therefore, a magnet having magnetic field uniformity which is as good as that of a magnet having a long center hole moreover a short center hole can be obtained.
