Title: Speed reduction control system of scanning system
Inventor: SUGIURA MASAMICHI
IPC: G03G15/04
Filed: 1982-08-10
Abstract: PURPOSE:To start braking a scanning system at invariably optimum timing in any mode by correcting the braking timing all the time on the basis of data measured during the precedent braking of backward movement, and starting the braking at the optimum timing. CONSTITUTION:The braking of the scanning system 1 is started with (TM) delay of a braking delay counter (TM) in a microcomputer after a braking switch SW-B is turned on by the scanning system 1, and its counted value (TM) is corrected by data on the measurement taken during the precedent braking. The braking is carried out in the order of a regenerative brake and a forward rotation brake and when the scanning system is braked to a specific speed, the speed is maintained by constant-speed control to stop the scanning system 1 when the system turns on a home switch SW-H. Its movement distance in the constant- speed control is measured and used to correct the braking delay counter (TM). Actually, preliminary forward and backward movement is performed when copying operation is started and the correction is made by using the measured data. Then, the correction is made successively on the basis of data obtained in a precedent copying return.

IPC: H04N5/44
Filed: 1991-06-12
Abstract: PURPOSE:To provide an on-vehicle display device which does not require the addition of a special signal wire when an automatic selecting mechanism for image screen is installed on a vehicle which is not equipped with the automatic selecting mechanism. CONSTITUTION:In the traveling of a vehicle, a traveling/stop judging circuit 4 outputs a state signal of logic '0', and a composite image signal superposed with the state signal is outputted to a receiving side through a signal wire 8 from a transmission signal selecting switch 6. A polarity judging circuit 10 on the receiving side separates the state signal from the composite image signal, and outputs the state signal into an AND circuit 18 and a polarity reversing circuit 12. Since the state signal of logic '0' is inputted into the AND circuit 18, the control signal outputted from the AND circuit 18 is always logic '0', independently of the other signal which is inputted into the AND circuit 18, i.e., the signal supplied from a manual switch 16. Accordingly, a computer image signal is always selected by a signal selecting switch 14.

IPC: H04B10/116
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To make it possible to easily produce a directional angle varying element without requiring metal dies at the time of production and to easily change the directional angle of an optical signal transmission and reception module by refracting incident rays on a laminated structure to a desired direction, thereby changing the spread of the rays. SOLUTION: The directional angle varying element 10 consists of the multilayered structure 11 formed by laminating and adhering plural films or sheets or thin films 11a to 11e varying in refractive indices. The change in the refractive indices of the respective layers 11a to 11e in the directional angle varying element 10 are formed by gradually lowering the refractive indices from, for example, the layer 11a to the layer 11e on the changes of the refractive indices are formed conversely by gradually elevating the refractive indices from the layer 11a to the layer 11e. Ceramics having a high IR transmittance, such as, for example, calcium carbide, alkaline earth metal compounds and silicon nitride, are used as the materials of the respective layers 11a to 11e. The refractive indices are varied by regulating the contents of sulfides, nitrides and borides.

Filed: 1996-06-03
Abstract: PROBLEM TO BE SOLVED: To change the irradiation area in right and left by providing a control means for controlling an irradiation area changing means on the basis of the final irradiation angle so as to change the irradiation area. SOLUTION: An irradiation angle deciding means 13 decides the final irradiation angle on the basis of a first irradiation angle θ1 , which is based on the steering angle θ, and a second irradiation angle θ2 , which is based on the yaw angular velocity θ. In this method for decision, a judgment whether the first irradiation angle θ1 and the second irradiation angle θ2 are oscillated in the same direction or not, namely whether they are the same code or not is performed, and amplitude of the oscillation, namely, each absolute value |θ1 |and |θ2 | are compared with each other so as to decide the final irradiation angle θ.  Control signal based on the final irradiation angle θ is output to a motor driver 24, and a left and a right motors 8 are driven by the motor driver 24 so as to oscillate a headlight at the irradiation angle θ. Distribution of luminous is really controlled on the basis of the final irradiation angle θ, and even in the case where sudden steering operation such as a counter steering is performed, change of the irradiation area is appropriately restricted, and a driver does not feel the uncomfortableness.

Abstract: PURPOSE:To improve a processing speed by setting up decision points on odd- numbered outline coordinates or its preceding coordinates and even numbered outline coordinates or its succeeding coordinates, setting up an image element between both the decision points and clearing and painting out an unnecessary decision point. CONSTITUTION:A decision point setting means sets up a decision point on the odd numbered outline coordinates or its preceding coordinates in a scanning point and also sets up a decision point on the even numbered outline coordinates or its succeeding coordinates. A painting out means scans a space between the set decision points, starts the setting of an image element at the odd numbered-th decision point or its succeeding coordinates and ends the setting of the picture element at the even umbered decision point or its preceding coordinates. In this case, the unnecessary decision point is cleared. Although outline coordinate information is previously required, the original pattern information is restored by the painting-out processing after setting up the decision points, so that the processing speed can be improved.
