Title: Actuator for constant-speed travelling device
Inventor: TOMINAGA TSUTOMU
IPC: F02D29/02
Filed: 1982-04-19
Abstract: PURPOSE:To precisely operate an actuator irrespective of any change in a negative pressure in a suction air tube, by arranging such that a negative pressure introducing tube of an actuator driven by a negative pressure in the suction air tube of a constant- speed travelling device for vehicles is provided with a control valve adapted to vary its opening amount in response to a negative pressure being applied. CONSTITUTION:A throttle valve 13 in a suction air tube 12 is connected with a diaphragm 4 via a cable 15. Difference between a signal indicative of actual vehicle speed and a target speed is computed by a control circuit 18, and depending on a degree of difference a diaphragm inside a pressure chamber 1 is operated by controllably opening and closing solenoid valves 7 and 8 for a negative pressure and an atmospheric pressure of an actuator. A valve 22 is provided intermediately at a portion between a suction air tube and a negative pressure introducing tube of the actuator, the valve 22 being adapted to control its opening amount depending on the negative pressure inside the suction air tube. Thus it is made possible to open the valve 22 and thereby maintaining a constant flow rate of fluid to be introduced into a pressure chamber 1 for retaining the diaphragm at a constant displacement magnitude even when there takes place a negative pressure drop in the suction air while a vehicle is travelling under an increased load.

Abstract: PURPOSE: To achieve the improvement in product quality and the higher speed of working by separately driving a punch holder and die holder, detecting their respective check points and aligning the origins of both holders then driving the press.  
     CONSTITUTION: Detecting discs 50, 58 provided respectively with the holes for detecting the origin and check point are provided to a punch holder 1 and die holder 11 which are independently driven and the check points of both holders are detected by using light emitting diodes or the like. The outputs of these two detection signals are put into a decision unit which in turn detects the coincidence and non-coincidence of the check points. The point where they coincide is made the origin. Here, the directions of the punch 21 and die 22 are accurately aligned and with this as a start point, NC motors 7, 17 are driven to apply punching or the like to the work 49. This mechanism permits occasional checking of positioning errors owing to the errors in the origin setting and the operation defect of the driving mechanism part.

Title: Controller
Inventor: KONDOU MASAHIDE
IPC: G05B19/18
Filed: 1981-05-06
Abstract: PURPOSE:To drive moving bodies, such as tools, etc., at an appropriate speed, by obtaining gain set signals corresponding to gain selecting signals read out from a memory along with location target values of the moving bodies, from a gain regulator of a servo amplifier. CONSTITUTION:When a moving body is driven from a location target value to the next location target value under a condition where no one-sided load is applied on the moving body, a location target signal of the next location target value and a gain selecting signal are outputted from a memory 1 when an output signal which is to be used for reading out the next target value is added to the memory 1 from a controller 2. The location target signal is converted into an analog value at a DA converter 3 and added to a servo amplifier 4, and then, becomes a servo current after amplification. The servo current operates a servo mechanism 7. When the servo mechanism 7 is operated, a feedback signal corresponding to the operation of the servo mechanism 7 is added to the feedback input terminal of the servo amplifier 4 from a potentiometer 9 in the direction where the servo current becomes 0 (zero). Therefore, the servo mechanism 7 finally stops at a point of time where the servo current becomes 0 (zero). The gain selecting signal has a constant value and this is given to a gain regulator 5.

Filed: 1987-03-20
Abstract: PURPOSE:To improve the operability by displaying a setting value of a picture variable power means on a display section on an operation panel, and keeping the display for a prescribed time even after an original is read. CONSTITUTION:A variable power value is set, displayed on an LCD and the setting value is kept on the LCD for a prescribed time after the communication is finished. Thus, when the communication is desired to be continued with the same setting value (variable power) consecutively, it is not required to apply various settings from the start and the operation is simplified. Further, since the setting value is restored to the initial value, after the operation at a setting value is finished and the other user uses the equipment, the operation to restore the setting values is not required and the start of communication with different setting can be avoided.

Abstract: PURPOSE:To prevent erroneous operation by providing such an arrangement that when a sheet present signal is received from a sheet detecting means after the number of sheets counted by a counting means reaches a predetermined number, a stapling device is allowed to operate, and after stapling, the operation of the stapling device is inhibited until a sheet unpresent signal is received. CONSTITUTION:In an automatic staple mode, sheets from an introduction port 47 in a finisher device 23 enter into a conveying path 70 through a flapper 67, and are detected by a counting means 72 so as to count the number of sheets. Then, the sheets are fed through a pair of discharge rollers 73 onto a staple tray 52a, and abuts against a stopper 63 to be aligned and loaded. Further, when the counted number reaches a predetermined value, a control device confirms the presence of the sheets by means of a sheet detecting means 74, and a stapler 75 staples the bundle of sheets. After stapling, a solenoid 76 is energized to retract the stopper 63, and therefore, the bundle of sheets is stored in a storage tray 65. When the sheet detecting means 74 is turned off, the operation of the stapler 75 is inhibited. Thus, it is possible to prevent the double punching of the stapling device.
