Title: Video amplifying circuit
Inventor: YOSHIMI TOMU
IPC: H04N9/00
Filed: 1982-02-15
Abstract: PURPOSE:To minimize cross color interference and beat components of 920KHz even in playback mode of VTR and to reproduce a sharp picture, by separating or adding a comb-shaped filter and a trap circuit from and to a video amplifying circuit. CONSTITUTION:During reproduction of VTR, the comb-shaped filter circuit 3 is disconnected from between the amplifying circuit 2 and a luminance signal processing circuit 4 and the output terminal of the amplifying circuit 2 is connected directly to the processing circuit 4 through an electric path 9. The switching between the both is carried out through the electric path 9 and changeover switches 11 and 12. Further, the 3.58MHz trap circuit 10 is added to the input terminal of the processing circuit 4 to remove a chrominance signal component from a playback video signal of VTR as a substitute for the comb-shaped filter circuit which does not have the function for removing the chromainance signal component. In some mode other than playback mode, the the changeover 11 and 12 are operated to connect the trap filter 3. The trap circuit 10 is connected through a switch 12 which is operatively associated with the connecting operation of the changeover switches 11 and 12. Thus, color signal interference is prevented even during VTR reproduction.

IPC: H02P3/00
Filed: 1978-02-28
Abstract: PURPOSE: To eliminate the disconnecting switch dedicated for braking and to improve the reduction effect by shortcircuiting between each phase of armature circuit for electric rotary machinery by means of the disconnecting switch for grounding inserted between main transformer and a circuitbreaker connected to the system.  
     CONSTITUTION: When stopping command is provided during generating or pumping operation of generator motor, 1 the circuitbreaker 7 and the field circuitbreaker 15 are opened to disconnect the generator motor 1 from the system 9 while the disconnecting switches 11-1, 11-2 for grounding are closed to shortcircuit the transformer 6 through the armature circuit for the generator motor 1. Then a current is supplied from the exciting circuit 17 to the field winding 16 such that the shortcircuit current flowing through the generator motor 1, transformer 6 and the disconnecting switches for grounding 11-1, 11-2 is approximately same with the rated current thus to perform the braking. Since the disconnecting switch dedicated for braking is eliminated and the armature circuit is shortcircuited through the transformer, the resistor loss is increased and the speed reduction is quickened.

IPC: B62D6/02
Filed: 1992-02-10
Abstract: PURPOSE:To improve the turning performance of a vehicle without hindering the travelling safety of a vehicle in the case where front wheels are steered slowly or a vehicle turns by steady turning. CONSTITUTION:A micro computer 34 performs the low pass filter computing to a detected front wheel steering angle thetaf from a front wheel steering angle sensor 31 with the program processing to extract the low area component thetafLP of the front wheel steering angle thetaf, and subtracts the low area component thetafLP from the detected front wheel steering angle if to compute the front wheel steering angle thetaf* (=thetaf-thetafLP), from which the low area component thetafLP is eliminated. The micro computer 34 controls the steering of rear wheels at an objective rear wheel steering angle thetar* (=K.thetaf*) in proportion to the front wheel steering angle thetaf*. In the case where the front wheels are steered quickly, the rear wheels are steered large in the same phase with the front wheels to keep the travelling safety of a vehicle favorably. In the case where the front wheels are steered slowly or a vehicle turns by steady turning, since the rear wheels are steered small or not steered, the turning performance of the vehicle is improved.

Abstract: PURPOSE:To minimize the variation of equivalent inductance, by providing a frequency controlling electrode having a larger area than the main electrode on one of the said main electrode. CONSTITUTION:The main electrodes 5 and 6 of the same area are attached symmetrically and opposite to both surfaces of the quartz plate 1 and then connected to the pin terminals 81 and 81' of the base board 8 to be supported there by the support lines 9 and 9' composed of the conductors connected to the electrodes 5 and 6 respectively.
