Title: Speed controller for motor
Inventor: YOSHIOKA KANEHARU
IPC: H02P29/00
Filed: 1988-10-28
Abstract: PURPOSE:To enable an economical DC stabilizing power source to be used by detecting line voltage, and by applying it to the adding point of an adder circuit with a constant gain. CONSTITUTION:By a voltage detecting circuit 10, the voltage of a mo tor power source 9 is converted to a signal level and is applied to the adding point of an adder circuit 5 with a constant gain. Even if the voltage of the motor power source 9 is fluctuated due to this composition, a voltage level corresponding with the change component of the characteristic of a motor 7 itself due to a voltage difference is corrected by the change component of the voltage of the power source 9, and so the voltage fluctuation of the motor power source 9 is hardly influenced by a phase output waveform, and as its result, a phase- locked loop lock range can be sufficiently widened, and so by the motor power source 9, the voltage fluctuation is not required to be severely limited. As a result, an economical DC stabilizing power source can be used.

Title: Delay circuit
Inventor: ISHIAI TAIJI
IPC: H03K5/13
Filed: 1984-12-27
Abstract: PURPOSE:To make the trailing time delay unchanged against a short pulse width input and a high frequency input by connecting a base of a transistor (TR) to an inverting circuit input via a resistor and providing a capacitor charged by the TR between an output of the inverse circuit and common. CONSTITUTION:When the level of the input of the inverter 7 goes to L, a TR 8 is turned on and the capacitor 18 is charged rapidly via the TR 8. When the level of the input of the inverter 7 goes to H, the TR 8 is turned off and the potential at an output terminal 9 falls down along with the discharge curve having a time constant decided by the capacitor 10 and a resistor 11. Since the capacitor is charged momentarily by the TR, the trailing time delay is unchanged against the short pulse width input or the high frequency input.

Title: Oscillation output circuit for photoelectric switch
Inventor: FUKUYAMA TOSHIBUMI
IPC: H03K17/78
Filed: 1988-10-28
Abstract: PURPOSE:To make a photoelectric switch applicable to both a reflection type switch and a transmission type switch by providing a wire for short-circuiting a projector. CONSTITUTION:In the case of using a photoelectric switch as a transmission type switch, a power line (b) and a base of a transistor(TR) Q1 are connected directly by a wire (d). Since a base and an emitter of a Tr q13 are short- circuited, the TR q13 is turned off and also a TR q14 is turned off, and then a synchronization/asynchronization switching signal 2 is reset to switch a detection circuit and a PLL circuit of the post-stage into the asynchronizing type. Thus, the switch is used as the reflection type switch without the wire (d) and the transmission type with the wire (d), thereby allowing the switch to be used as a general-purpose switch.

Abstract: PROBLEM TO BE SOLVED: To prevent image quality deterioration by starting the print with a delayed timing with respect to the printing timing detected by the detecting means after finishing the print by the printing head in the case a printing timing is detected by a detecting means during the printing operation by a printing head. SOLUTION: In an ink-jet printer, with a recording paper 100 conveyed in a sub scanning direction and a carriage 104 moved in a main scanning direction, a slit of a linear scale 108 is detected by a linear sensor 110 so that the printing timing of a printing head 106 on the recording paper 100 is controlled according to the slit detection. The printing head 106 ejects an ink onto the recording paper 100 according to the controlled printing timing for forming an image on the recording paper 100. Even in the case the interval of the printing timing detection by the detecting means is shorter than a time interval needed for the printing operation, the printing operation is executed always corresponding to the printing timing detection. Accordingly, the image quality deterioration can be prevented.

Filed: 1996-09-27
Abstract: PROBLEM TO BE SOLVED: To eliminate the need for maintenance and control service for an equipment, to realize stable and uniform discharge at all times and to continuously obtain an excellent copied image by judging the propriety of starting cleaning in advance to the cleaning. SOLUTION: The operation of a cleaning device for a discharge electrode 1 and a shielding member 4 is performed simultaneously with turning on the power source of a copying machine (ordinarily, about once a day). Since a cleaning means need not be started plural times a day, the cleaning device is set so as not to be actuated when the power source is turned on again while a fixing device is warmed even after the power source of the copying machine is turned off inadvertently or for any reason or in the case of service maintenance. Namely, the operation of a cleaner supporting member 12 is inhibited while the fixing device is ready for copying operation, whereby waiting time is prevented from getting longer because of the cleaning of the discharger and the excessive cleaning operation of the electrode 1 is prevented.

Title: Slip control device for vehicle
Inventor: WATANABE MASAHITO
IPC: B60W10/188
Filed: 1991-10-23
Abstract: PURPOSE:To prevent the unprepared shift of speed change gear by providing a speed change control means which permits speed change gear shift only when a state where driving wheel speed is kept in a speed change gear range after shifting the speed change gears during traction control continues for time longer than fixed time even when the driving wheel speed changes to get over the boundary point of the speed change gear shift. CONSTITUTION:A speed change control means D executes speed change gear shift as follows; S1, during traction control; S2, when average rear wheel speed is less than a fixed value at which speed change shock is caused with hunting; S3, even when the average rear wheel speed changes to get over a speed change line (when the signal of shift up is given); S4, when the changing rate of the average rear wheel is more than fixed value; S5, in the case where the change gear shift is permitted by the speed change control means D only when a state where the average rear wheel speed is kept in speed change gear range after shifting the speed change gear continues for time longer than fixed time. Thus, in the case where either of right and left rear wheels spins greatly to rapidly make the average rear wheel speed higher, and the rear wheel speed return to original speed immediately after that, the speed change gear shift can not be done, and the hunting is effectively prevented.
