IPC: G03G15/00
Filed: 1987-01-30
Abstract: PURPOSE:To prevent a sheet from being electrified, eliminate the toner suction before the transfer position, and improve the image quality by using a conductive material for a roller feeding the sheet from a sheet feed section to a transfer section and electrically grounding the roller. CONSTITUTION:A sheet feed roller 1 is made of a conductive material, e.g., chloroprene, metal containing carbon, and it is grounded to a frame 3 by a FG plate 2 at one end or both ends of its shaft. When a conductive material is used for a bearing 17 in place of the FG plate 2, the same effect can be obtained. Accordingly, the electrification of a sheet by the roller is prevented, the toner suction before the transfer position is eliminated, and the image quality can be improved.

Title: Digital delay circuit
Inventor: HIRAI MASATO
IPC: H03K5/135
Filed: 1983-02-14
Abstract: PURPOSE:To attain very high accuracy in the setting error of delay time by forming the delay time with respect to an external input signal depending on the number of stages of counters and changing a clock frequency to set freely the delay time. CONSTITUTION:When an input signal turns on from the initial state of the circuit, a signal 9 turns on and a counter 13 starts counting a clock. Since the counter 13 turns on its delay output 12 after the count of 8 clocks, the signal 9 is turned off, the clock input to the counter 13 is stopped and the delay output is held. Even if the input signal is interrupted, the signal 9 is turned on similarly, the counter 13 counts for a prescribed time to turn off the delay output. When a hexadecimal counter is used for the counter 13, the counter output is turned on and off at every count of 8 clocks. Thus, although the delay time is given by the count corresponding to 8 clocks, the delay time becomes minimum 7 and maximum 8 clocks according to the relation between the input signal and the clock.

Title: Voltage controlled current source
Inventor: MIZUKAWA YOSUKE
IPC: G05F3/22
Filed: 1990-01-30
Abstract: PURPOSE:To attain the control of a voltage control current with high accuracy independent of the temperatures by applying feedback so as to secure the coincidence between the emitter voltage of a transistor TR which supplies a current to the load and the voltage of a control voltage source and then attaining the proportional control of the load current based on the control voltage. CONSTITUTION:The current mirror circuits of the TR 9 and 10 supply the collector current of the same level to the TR 6 and 7. As a result, the coincidence is obtained between the base voltage of the TR 6 and that of a TR 7. Therefore the voltage (control voltage) of a control voltage source 5 is set equal to the emitter voltage of a TR 2 which supplies a current to a load 1. Under such conditions, the load current is proportional to the emitter current of the TR 2. This emitter current, however, is proportional to the emitter voltage. This emitter voltage is equal to the control voltage. As a result, the load current can be proportionally controlled by the control voltage. Thus the voltage control current is controlled with high accuracy independent of the temperatures.

Title: Speed controller of motor
Inventor: HATAKAWA MASAHARU
IPC: H02P29/00
Filed: 1984-02-10
Abstract: PURPOSE:To reduce the influence of a ripple of a frequency/voltage converter (F/V converter) at a low speed by inserting a voltage divider into a speed feedback circuit at a low speed time. CONSTITUTION:In order to use a voltage 24 divided by a voltage divider 15 from the output signal 23 of an F/V converter 11 as a speed feedback voltage 27 at a low speed operation time, a ripple voltage due to F/V conversion is divided, and the ripple voltage becomes 1/n of the voltage dividing ratio as compared with the conventional one. On the other hand, since the voltage 27 holds the same linearity as the conventional one, S/N ratio is improved, and the control limiting speed at a low speed becomes 1/2 of the speed as compared with the conventional one, thereby obtaining a wide speed controlling range.

Title: Control of step feed quantity
Inventor: ISHIWAKI TAKESHI
IPC: B23Q5/50
Filed: 1987-02-03
Abstract: PURPOSE:To permit the step feed without calculating the interpolation data for each step quantity by shifting a table in each feed time at the calculated interpolation speed in the step feed in each constant distance on a straight line or a circular arc, in an NC machine tool. CONSTITUTION:In the contouring grinding on the horizontal spindle surface grinder, the interpolation speed V and feeding time  t for obtaining  l=VX t is obtained for the designated step quantity  l in a controller. Then, the interpolation data for shifting a magnet 21 on the circular arc A-B of a work 22 on the XZ plane is calculated on the basis of the transfer paths A-B and B-C of the magnet 21, and said result is set into a function generator for controlling the two-axis contour. When interpolation operation is started with the interpolation speed V, the YZ axis shifts by  l, e.g., by the line segment between the stop points n and n+1 in each step quantity feed, and after the feeding time  t, a table is shifted along the X axis, and grinding is carried out, and similar operation is carried out on the circular arc BC having a radius R2. Therefore, step feed in each constant distance is carried out without calculating the interpolation data for each step quantity.

Title: Navigation system for vehicle
Inventor: MORIMOTO MITSUKI
IPC: G06F19/00
Filed: 1996-01-14
Abstract: PURPOSE: To enable it to properly output both automatic and request voices by installing a judging means judging of whether any guide information is requested from a driving car or not. CONSTITUTION: A route guide part 1-2 judges of whether one's own car comes nearer to a guide point preset to a position on a car lane or not. Accordingly, timing for automatic voice output at the specified distance short of an intersection on a guide route is thus judged. A phrase stored in a voice buffer 4-1 on the basis of this judged result is outputted in such a voice as converted by a decoder 4-2. When a driver requests a route guide by an input part 7, a request sensor 7-1 (judging means) judges that it is requested by the driver's own will, emitting such a signal as instructing an, operational part 1 to do a navigation procedure. In brief, if there is a request, a guide voice is emitted. Therefore, even during guidance through an automatic voice output, it is suspended and it is selected to the newly requested guide.

Abstract: PURPOSE:To control the rotation speed of a fan according to connecting and disconnecting of an option part, by providing an interface capable of detecting the fact that the option part is connected to a power supply connector of the option part where the temperature rise is strictly limited. CONSTITUTION:The rotation speed of a fan 7 is variable corresponding to voltage. And, one of the terminals of the fan 7 is connected to a DC voltage VA, and the other to a ground via a resistor 8, and to a power supply connector 6' of an option part 5 via a resistor 9 including a resistance value 0OMEGA. A ground terminal is provided on the power supply connector 6' of the option part 5, such as a hard disc, etc. having a large power consumption, where the temperature rise is strictly limited. Therefore, when the option part 5 is not connected, a voltage divided by the resistor 8 is applied to the fan 7, causing the rotation speed of the fan 7 to be lowered. On the other hand, when the option part 5 is connected, a voltage divided by the resistors 8 and 9 in parallel is applied to the fan 7, allowing the fan 7 to rotate at a rotation speed required for cooling the option part 5.
