Title: Voltage declining circuit
Inventor: MIYAZAKI TAKAHARU
IPC: H02M3/07
Filed: 1981-02-12
Abstract: PURPOSE:To decline a voltage in the state an input and an output are isolated without using a transformer by combining a plurality of capacitors and a switch. CONSTITUTION:When swithces S1, S2 are closed and switches S3-S6 are opened (during T1), capacitors C1, C2 are charged, and the terminal voltages of both the capacitors become equal. When switches S3-S6 are closed and switches S1, S2 are opened (during T2), the capacitors C1, C2are connected in parallel with the capacitor C3 through the switches S3, S6 and S4, S5. Because, two capacitors C1, C2 are connected in series between the input terminals 1a and 1b during T1, the voltage of 1/2 of the DC voltage V0 applied between the input terminals can be obtained at the respective capacitors, and accordingly the voltage of V0/2 can be obtained between the output terminals 2a and 2b during T2.

Filed: 1996-02-06
Abstract: PROBLEM TO BE SOLVED: To change a direction of advance of one's own vehicle easily and precisely by controlling vehicle speed on the right and left of one's own vehicle when it is judged that one's own vehicle does not travel in a desired direction of advance and compensating the direction of advance of one's own vehicle. SOLUTION: Since a first advance direction control means 11 drives a wheel steering device 12 and controls steering angles of steering wheels 4, 5 based on the detection result of a camera device 10 to change a direction of advance, the direction of advance can be easily changed by a comparatively large degree. Moreover, whether one's own vehicle 3 travels along white lines 1 and 2 or not is monitored based on the detection result of a camera device 13 at the same time. When it is detected that one's own vehicle does not travel along the white lines 1 and 2, a second advance direction control means I4 drives controllers 15 or 16 and gives turning force to one's own vehicle 3 to compensate the direction of advance of one's own vehicle 3.  Since the second advance direction control means 14 obtains turning force by changing a difference in speed between right wheel and left wheel, it is possible to adjust the direction of advance minutely and easily.

Title: Video signal controller
Inventor: MIZUTANI TETSUO
IPC: H04N5/44
Filed: 1983-02-10
Abstract: PURPOSE:To prevent flickering of screen at channel operation and mixing of noise or the like from being given to the visual sense by producing a video control signal and by using this signal to apply luminance control of screen other than at normal picture signal. CONSTITUTION:When a channel selecting signal is applied via a lead wire 20, a channel controller 10 gives a data signal to control a video signal to a data signal input terminal 3 and supplies a latch signal to a latch signal input terminal 4 at the same time.A video control means 1 receiving the two signals takes a background display signal applied to a background display signal input terminal 2 as an input signal and a vertical synchronizing signal applied to a vertical synchronizing signal input terminal 5 as a synchronizing signal to output the video control signal to a video control signal output terminal 9. This signal controls the video signal to decrease the luminance resulting that the screen is dark for the period T from the point of time X at channel switching into the time point Y at which the tuning is finished. Thus, no flickering or noise appears on the screen during this period.
