Title: Television camera control system
Inventor: YAMADA KUNIHIRO
IPC: H04N5/232
Filed: 1985-12-27
Abstract: PURPOSE:To require no operation of a camera (adjustment of direction and focal point) and to always catch an object at the center of a picture even when the object moves by using an ultrasonic oscillator emitting an ultrasonic impulse provided in the object to make the direction and the focal point of the television camera coincide with said ultrasonic oscillator. CONSTITUTION:An oscillation control signal S1 is emitted from an instrumentation calculating controller CNTL, and then, the ultrasonic impulse is emitted from the ultrasonic oscillator T. This impulse is propagated in the air and reaches to four ultrasonic oscillation receivers R1-R4 disposed on the television camera main body CMRA side. Knowing the reach time t of the signals R1-R4, it is calculated by the known method according to a trigonometrical survey, what is called. Thereby, the distance d between the ultrasonic oscillator T and a lens and an angle theta to be directed vertically are obtained. Thereby, the instrumentation calculating controller CNTL transmits an angle control signal Sc to an electric universal head EVRA to rotate and move an optical axis of the camera vertically by theta deg..

Title: Input circuit
Inventor: KAWADA KAZUHIDE
IPC: H03M11/20
Filed: 1985-12-27
Abstract: PURPOSE:To fix an input circuit at one of both states in case a data input line is shared by plural circuits by using an N channel metallic film MOS transistor as the pull-down resistance of a data line. CONSTITUTION:An N channel MOS transistor (Tr)16 having high ON resistance is used as the pull-down resistance of a data line 14. Then the input reading timing is applied as the gate input of the Tr16 and the NAND is secured between this gate input and and the line 14. Here an input control signal line 15 has the voltage of a low level in the states other than the input reading timing. While the output of NAND17 is fixed at a low level of voltage. The line 15 has the voltage of a high level with the reading timing and the Tr16 is turned on and serves as a resistance. At the same time, the NAND17 serves as an inverter to the line 14 with coincidence secured with a normal input circuit. Thus the effect of the input circuit is eliminated when no input of data is supplied at the input circuit side. Then the input circuit can be fixed at one of both states.

Abstract: PURPOSE:To eliminate a mechanically movable part and to improve the durability by providing a vibration body which generates an ultrasonic traveling wave and generates a thrust by the friction against a recording medium and a writing tool which moves on the recording medium with the thrust of the vibration body. CONSTITUTION:An AC voltage E1 is applied between piezoelectric layers 15 of a couple of vibration bodies 12a and 12b and a voltage E2 which is equal in frequency, but delayed 90 deg. behind the voltage E1 is applied between piezoelectric layers 16.

A device 1 is moved on the medium 2 with the thrust of the vibration bodies 12a and 12b as shown by an arrow X. Similarly, the vibration bodies 12c and 12d are made to generate a thrust for moving the device 1 as shown by an arrow Y. Then, the voltages applied to four vibration bodies are made different in phase and level to move the device 1 in optional directions, thereby recording an optional graphic form 3 on the medium 2 with the writing tool 13.
