Title: Feeder for rolled drawing sheet
Inventor: YAMAMOTO AKIHIRO
IPC: B43L5/00
Filed: 1987-12-13
Abstract: PURPOSE: To shorten the design time while preventing waste of drawing paper by providing a body being fixed to a drawing table, and a member provided on the body in order to support the drawing paper rotatably and removably while being engaged with the central part thereof. CONSTITUTION: Specified length of a drawing paper is drawn out by pulling the end part of a roll paper W and applied onto a drawing table 11 before starting design. The roll paper W is turned on first and second positioning members 7, 8 or turned integrally on a supporting bar 6 and drawn out sequentially. The part to be cut off upon finishing design is set at the position of a cutter 9 which is then moved along a guide rail 10. Since a required quantity of drawing paper W is fed while continuing design work and the drawing paper W is cut into a length corresponding to the drawing upon finishing design, the work for examining the required length can be eliminated and the design time can be shortened correspondingly. Furthermore, the cutter 9 can be translated surely through a simple work relative to the roll paper W.

Title: Method of preventing stall of asynchronous machine
Inventor: SAMURI HEITSUKIRAA
IPC: H02P23/08
Filed: 1990-11-20
Abstract: PURPOSE: To prevent the overload of a machine by a method, wherein a controller performs a control such that the torque of an asynchronous machine is not increased when an angle between vectors parallel to the magnetic flux of a stator and a rotor or a value proportional thereto corresponds to a predetermined angle between the vectors of the magnetic flux of the stator and the rotor. CONSTITUTION: The rotational vectors of the stator current and the stator voltage of a machine are measured to determine two vectors, one of which is parallel to the direction of the magnetic flux of a stator and the other of which is parallel to the magnetic flux of a rotor, on the basis of the rotational vectors of the measured stator current and stator voltage and the short-circuiting inductance σLs of the machine. Next, an angle θ between the vectors parallel to the magnetic flux of the stator and the rotor and a value proportional thereto is determined. When the angle θ or the value proportional thereto corresponds to a predetermined angle between the vectors of the magnetic flux of the stator and the rotor, a controller 6 performs control such that the torque of an asynchronous machine is not increased.

Title: Operation control method of agitation-type washing machine
Inventor: TOKUCHI MASAYUKI
IPC: D06F33/02
Filed: 1990-11-21
Abstract: PURPOSE:To prevent the generation of the breathing phenomenon of an agitating blade to obtain an appropriate stop determination time corresponding to the strength of a stream by starting a conduction in the direction opposite to a motor, when an interval between pulses of inertia exceeds a predetermined value after a predetermined stop determination inhibition time has elapsed often the stop of conduction to the motor at the time of operation through a reference stream. CONSTITUTION:A reference stream is smaller in the conduction angle to a motor 10 than a power stream, and the conduction to the motor 10 is stopped when the motor rotates 5.5 times as specified or the conduction time to the motor 10 reaches the specified longest operating time even if the motor has not rotated 5.5 times yet. According to the stop determination after the stop of conduction to the motor 10, when a specified stop determination inhibition time has elapsed and thereafter an interval between pulses of inertia reaches a predetermined value, e.g. 110msec or more even if the motor 10 does not rotate once after the stop of the conduction, the motor 10 is judged to stop almost perfectly and power is applied in the direction opposite to the last time. Thus, the stop determination can be conducted accurately.

Title: Method of encoding/decoding of digital picture signal
Inventor: JIYATSUKU GISHIYAARU
IPC: H04N7/32
Filed: 1988-12-16
Abstract: PURPOSE: To enable a reduced-speed image transmission without any loss of information by generating additional image information according to a difference between an input digital signal and a coded signal when a momentary speed of a 1st transmission line is slower than information speed of a coding device, and sending it to a 2nd transmission line. CONSTITUTION: A coder 11 outputs a quantized and coded digital error signal (e). This error signal (e) is transmitted to a decoding device 2 through a 1st variable-speed transmission line 31. When a network 3 is able to dispatch the total information transmission speed that the main coder 11 can provide through the transmission line 31, an auxiliary coder 14 does not operate and the image information is not dispatched through the transmission line 32. When the network 3 is overloaded, the coder 11 decreases the number of quantization levels of the signal X. The auxiliary coder 14 begins to operate and send a non-zero signal ea out through the transmission line 32. According to additional information regarding the signal X, the signal X having precision that the decoding device 2 requires can be recovered.
