Filed: 1992-05-13
Abstract: PURPOSE:To suppress current consumption at the time of stoppage by providing means for repeating forward and reverse rotations of a step motor at a predetermined period to stop the step motor apparently, and means for releasing stoppage of the step motor. CONSTITUTION:The step motor drive circuit comprises means for repeating forward and reverse rotations of a step motor at a predetermined period, upon heading of paper, to stop the step motor apparently, and reverse for releasing stoppage of the step motor after reception of print data. Exciting pulse (a) for phase A, exciting pulse (b) for phase A', exciting pulse (c) for phase B, exciting pulse (d) for phase B', exciting current (e) for phase A, and forward/ reverse interval (f) of the step motor are shown on the drawing. Since forward and reverse rotations are repeated to repeat corresponding exciting patterns as shown on the drawing, current consumption is reduced as shown by the exciting current (e) for phase A on the drawing.

Title: Constant current circuit
Inventor: YOSHIKAWA KIMIMARO
IPC: G05F1/56
Filed: 1978-09-29
Abstract: PURPOSE: To facilitate the integration without enlarging the joining area between the emitter bases by inserting the variable resistance between the current output end of the first current Miller circuit and the current input end of the second current Miller circuit.  
     CONSTITUTION: Between the output end of the first current Miller circuit (Q 1 , Q 2 ) and the input end of the second current Miller circuit (Q 3 , Q 4 ), the resistance R 2  is connected. By changing this resistance, the current flowing through the transistors Q 1 , Q 2  can be made different and the collector current of the transistor Q 2  can be made as output of the second current Miller circuit. Thus, since the differnet collector currents can be flowed without enlarging the joining area of the emitter bases of the transistors, the high integration of the integrated circuit may be possible.

Title: Multiplying circuit
Inventor: NISHIKAWA AKINARI
IPC: G06F7/53
Filed: 1983-07-05
Abstract: PURPOSE:To obtain an approximate answer with high accuracy by using two digital signals as the multiplicand data X and a coefficient (a) respectively and then applying addition/multiplication to the multiplication a.X by means of a combination of 2<alpha>.X and 2<beta>.X. CONSTITUTION:The multiplicand data X is supplied to the 1st and 2nd shift registers 13 and 17 through input terminals 11 and 15 respectively. At the same time, a coefficient (a) is fed to a decoder 21 through an input terminal 19. A shift register 13 shifts the data X toward the alpha-bit MSB (maximum bit) side and delivers it to an addition means 25 in the form of the 1st output signal 2<alpha>.X. The 2nd shift register 17 shifts the data X toward the beta-bit MSB side to deliver it to a selection means 23 as well as a producing means 27 for complement of 2 in the form of the 2nd output signal 2<beta>.X. The means 27 produces a complement signal -2<beta>.X, i.e., a complement of 2 to deliver it to the means 23. Then the means 23 selects 2<beta>.X or -2<beta>.X in response to the code information given from the decoder 21 and delivers it to the means 25. The selected 2<beta>.X or -2<beta>.X is multiplied by 2<alpha>.X, and 2<alpha>.X+ or -2<beta>.X is delivered to an output terminal 29.

Filed: 1986-05-28
Abstract: PURPOSE:To dispense with resistors and eliminate overvoltage, by setting a semiconductor switch to be of a phase angle control system, and by increasing the current angle slowly to suppress rush current to a capairtor. CONSTITUTION:With AC voltage from terminals 1, 2, a condenser 20 is charged via a transformer 13, a diode bridge 14, and resistors 15, 20. when the charged voltage comes to the breakover voltage of a pulse element 19 or more, then the voltage flows to the gate of a thyristor 17 through the pulse element 19. Besides, the luminous diode 16 of a photocoupler 6 connected to the thyristor 17 in series is illuminated and is received by a photodetector 7, and a semiconductor switch 8 is put in a conductive state. As a result, the charged voltage flows to a smoothing condenser 12, and the then conduction angle of the switch 8 is set to be the same as that of the thyristor 17, and so the current flows in a narrow state and rush current is suppressed. when the potential of the condenser 12 is risen and comes to Zener voltage or more, then the thyristors 17, 8 are always set in an ON-state via a thyristor 25.

Title: Optical device with variable focal length
Inventor: MATSUMURA KATSUYA
IPC: G02B3/14
Filed: 1999-04-28
Abstract: PROBLEM TO BE SOLVED: To provide the variable-focal-length optical device which can be made small-sized. SOLUTION: A substrate 1 is a flat plate type substrate which is made of stainless steel and has a specular surface 2 as one surface, and serves as an electrode of a piezoelectric body 3. A control part 6 is a controller including a power source which applies a specific voltage between the electrode 2 and an electrode 5. The piezoelectric body 3 when applied with a specific voltage deforms, for example, as shown by arrows to distort the substrate 1 into a concave mirror. Its focal length is variable with the applied voltage. The substrate 1 itself, therefore, has a specular surface, so the control part including the power source is only provided to obtain the optical device with variable focal length.

IPC: G02B6/24
Filed: 1985-06-05
Abstract: PURPOSE:To obtain a necessary working space without removing surplus length housing cases above the 2nd and subsequent layers of said cases even with said cases by increasing the length of a supporting bar in the stage of putting in and out of surplus length parts. CONSTITUTION:An operator removes the cap of a box body 2 and increases the length of the case supporting bar 4 in the stage of putting in and out of the surplus length parts of optical fibers. More specifically, the operator lifts the surplus length housing case 3' upper than the specific surplus length housing case 3 along the supporting bar 4. Then the bar 4 is long and therefore the required working space 11 is assured between the specific case 3 and the case 3' above the same. The operation for putting in and out of the surplus length parts of the optical fibers is thus made easy by utilizing the wide space 11.
