Title: Television camera apparatus
Inventor: YOSHIMURA YASUO
IPC: H04N5/222
Filed: 1996-12-19
Abstract: PROBLEM TO BE SOLVED: To improve the operability and practicability of a camera head part by controlling a switching circuit in accordance with either a camera controlling part or a recording device which are connected to a connecting unit. SOLUTION: An output of a switching circuit 7 is connected to a RET terminal 9, and in the case of system connection, the terminal 9 becomes a VFRET signal (system return signal to be sent to a viewfinder) output terminal. In a self-contained system, the terminal 9 becomes a CAMRET signal (signal that inputs a camera output from other camera head and displays it on the viewfinder) input. A control signal input terminal of a switching circuit 17 is connected to a camera side CPU circuit 11, and a terminal 18 has two functions by means of the same operation with a RET system. That is, in the case of a system connection system, a PROMPT signal is outputted, and at the time of the self-contained system, a GL signal which is a signal of a synchronous combining circuit 19 is inputted. This brings about the reduction of the number of terminals.

Title: Method for controlling amount of aqueous urea to be added to exhaust gas denitrator
Inventor: YAMASHITA NOBORU
IPC: B01D53/34
Filed: 1989-12-27
Abstract: PURPOSE:To use aq. urea with the concn. variable as a reducing agent by successively measuring the urea concn. in aq. urea to be added to an exhaust gas, calculating the requisite amt. of aq. urea to be added based on the measured value and controlling the actual amt. of aq. urea to be added. CONSTITUTION:Aqueous urea is added to the exhaust gas from an internal-combustion engine 1 as a reducing agent and brought into contact with a catalyst to reduce the nitrogen oxides in the exhaust gas. In this case, the urea concn. in the aq. urea to be added is continuously and successively measured by a urea concn. meter 13. The requisite amt. of aq. urea equivalent to the requisite amt. of urea to be added is calculated by a computing element 9 based on the measured value. The opening degree of an aq. urea flow control valve 12 is corrected based on the calculated value, and the aq. urea equivalent to the requisite amt. of aq. urea to be added is added to an exhaust gas duct 2. Consequently, aq. urea with the concn. variable is used as a reducing agent without using a constant-concn. aq. urea prepared with a constant-concn. continuous dissolver, and the amt. of aq. urea to be added to the exhaust gas is accurately controlled.
