Abstract: PURPOSE:To eliminate the need for a DC blocking capacitor between an output terminal and a signal line by making a DC potential of the output terminal of an output circuit of the television camera equal to a voltage of a video signal transmission line. CONSTITUTION:A positive pulse from a pulse generating circuit 6 is fed to a diode D1 through a capacitor C2 and rectified to set a potential of a capacitor C3 to be Vf (power supply voltage) +Vp (positive pulse rectified voltage) and it is fed to a positive power terminal of an operational amplifier 2.

Title: Matrix switch sensing system
Inventor: TAKEKOSHI TOSHIO
IPC: G06F3/048
Filed: 1983-05-24
Abstract: PURPOSE:To detect accurately a closed contact during high-speed scanning even in case of a matrix switch having a high resistance value when the switch contact is turned on, by connecting switching elements in parallel to resistances for pull-up of sense lines. CONSTITUTION:Field effect transistors (TRs) T1-Tm are connected in parallel to resistances R1-Rm. If a bipolar TR Q1 is turned on when only a switch contact S11 is closed, a potential V1 of a sense line X1 falls to about ''0'' volt, and a sense circuit detects the contact S11 as a closed contact. Thereafter, when the TR Q1 is turned off and a TR Q2 is turned on, the TR T1 is turned on to short-circuit the circuit between both ends of the resistance R1, and therefore, the potential V1 of the line X1 rises quickly. Then, the potential V1 is higher than a deciding threshold Vth when the TR Q2 is turned on, and therefore, a switch contact S12 is not detected erroneously as a closed contact. Consequently, the closed contact is detected accurately while scanning a matrix switch 1 in a high speed.

Abstract: PROBLEM TO BE SOLVED: To form a light distribution characteristic at traveling light distribution time in a bilaterally symmetrical shape, and enhance front distant visibility by moving a light source in the lateral direction relative to an installing state on a vehicle. SOLUTION: A light source 2 using a discharge lamp is composed so as to be switched to low light distribution and traveling light distribution by being laterally moved by a moving means 4 in an installing state on a vehicle relative to a reflecting mirror 3 having a paraboloid of revolution to shield the light reaching the lower half part of the reflecting mirror 3 except for a part by arranging a hood on the light source 2. When obtaining low light distribution, the light source 2 is set in a position S on the optical axis Z of the reflecting mirror 3 to form a light distribution characteristic in a bilaterally asymmetrical shape. When obtaining traveling light distribution, a quantity of lateral light is equalized by moving/setting the light source 2 to a left traveling position M point of a low position S to form a shape in bilateral symmetry.  Therefore, a driver can easily visually confirm a front distant place of a vehicle. A position of a traveling position M point is set in the left rear of an S point by the moving means 4 to bring the reflected light near to parallel beams of light.
