Title: Motor controller
Inventor: IKENOUE YOSHIKAZU
IPC: H02P29/00
Filed: 1985-02-20
Abstract: PURPOSE:To improve the response of control by controlling the rotating speed of a motor by the both rising and falling edges of a pulse encoder at a low speed rotation time, thereby shortening a control period. CONSTITUTION:A pulse signal of an encoder 2 shaped to a rectangular wave by a waveform shaper 3 is input to an interrupt generator 4. Here, the output of an OR gate becomes 'H' by the rising and falling edges of an encoder pulse at low speed time, and an interrupt request INTRQ is input to the terminal INT of a microcomputer 6. The microcomputer 6 obtains the optimum current flowing amount corresponding to the set rotating speed at every interrupt signal, and controls to output to a DC motor. The speed of the motor is controlled only by one of the rising and falling edges of the output pulse of the encoder.

Title: Method of sending sheet out
Inventor: YAMASHITA YOSHIHIKO
IPC: B65H3/08
Filed: 1985-02-22
Abstract: PURPOSE:To smoothly push a sheet out in sending out stacked sheets one by one from the uppermost sheet, by sucking the top of the sheet at both the side edges of the rear portion thereof to protrusively curve the central portion of the sheet downwards, pull it backwards and thereafter push it out forwards to prevent the sheet from buckling when it is sent out. CONSTITUTION:A pair of suction heads 3, 3 located over the rear portions of sheets 1 stacked on a table lifter 2 are moved down so that the uppermost sheet is sucked on the suction heads at both the sides of the rear portion of the sheet. The suction heads 3, 3 are then moved up to lift the sheet 1 and simultaneously incline it to protrusively curve the middle of the rear portion of the sheet downwards. The sheet 1 in that state is pulled backwards and then pushed forwards into between pinch rollers 4. The sheet 1 is thus provided with a flexural rigidity to prevent the sheet from buckling and clinging to the next sheet when the sheet is sent out, so that the sheet is smoothly pushed out forwards. As a result, the sheets can be sent out continuously and efficiently.

Filed: 1995-02-23
Abstract: PURPOSE: To provide the protection circuit for protecting a television receiver by detecting the abnormal state of a horizontal deflection system even in the case of television receiver having the case of opening/closing the power source of that system. CONSTITUTION: Under the control of a microcomputer 6, power is supplied to a main power source circuit 2 by turning on a main power source relay 1 and power is supplied to a flyback transformer 4 and a horizontal deflection circuit 5 by turning on a horizontal deflection circuit system power source relay 3. At such a time, the input signal of a transistor 7 corresponding to the opening/closing of the horizontal deflection circuit system power source relay 3 and a potential divided output caused by resistors 8 and 9 corresponding to the presence/absence of a second-order side rectified output from the flyback transformer 4 are inputted to a comparator circuit (AND circuit) 10.  When the compared result shows the closing of the horizontal deflection circuit system power source relay 3 and the absence of the second-order side rectified output from the flyback transformer, the microcomputer 6 opens the main power source relay 1, stops the input of the main power source circuit 2 and protects the circuit and parts. Since no abnormal signal is outputted while the horizontal deflection circuit system power source relay 3 is turned off, even when opening/closing the power source of horizontal deflection system, no erroneous judgement is performed.
