Title: Video signal processing circuit
Inventor: NODA MASARU
IPC: H04N5/208
Filed: 1984-01-25
Abstract: PURPOSE:To improve S/N of a video signal and sharpness of a picture by functioning a circuit as an S/N improving circuit with respect to a signal of a picture part which has either no upper/lower contour of the picture or a weak signal and as a picture sharpness improving circuit with respect to a signal whose picture has a strong contour. CONSTITUTION:The level of a limiter circuit 5 is set to the level equivalent to the noise level of a signal inputted into a circuit 5 from a comb-shaped filter 4 for extracting contour signals. An input signal of the circuit 5 fails to reach a limiter level at a part where no contour in an upper/lower direction is on the picture and passes through the circuit 5 as it is, thereby functioning as an S/N improving circuit. At the part where the upper/lower direction contour is on the picture, an amplitude of the input signal of the circuit 5 is large enough to exceed the limiter level, blocks the passage of the circuit 5, and functions as a sharpness improving circuit, thereby accomplishing sharpness improvement less in blur or less in S/N deterioration.

Title: Photodiode array detector
Inventor: TSUTSUDA KOUJI
IPC: G01N21/27
Filed: 1995-01-26
Abstract: PURPOSE: To improve S/N in the measurement of a single-beam light by providing a D/A converter circuit for receiving a signal approximate to a sample-side signal as a reference, and reducing the difference between both input signal levels on the sample side and the reference side of a LOG conversion circuit. CONSTITUTION: The light from a light source is transmitted through a flow cell 2 and split with a prism 3. The light is cast on a photodiode circuit 4. When a start signal is inputted from a control part 9, the circuit 4 outputs the bit signal corresponding to the wavelength in time series. The light signal becomes the S/H circuit signal in a sample-and-hold(S/H) circuit 5. At the background correction of eluate before sample measurement, an input signal changing switch 7 is shifted to the E side, and the S/H circuit signal is inputted into an AD conversion circuit 8. The digital value is stored in the control part 9 for every bit. Then, the switch 7 is shifted to the A side, and the signal of a LOG conversion circuit 6 is inputted into the A/D conversion circuit 8. Thus, the S/N of the entire apparatus can be improved by the noise limiting function of the LOG circuit 6.

Title: Combustion control device for lean burn internal combustion engine
Inventor: MIZUNO HIROYUKI
IPC: F01N3/24
Filed: 1999-01-19
Abstract: PROBLEM TO BE SOLVED: To surely prevent the generation of shock occurred at the time when rich spike process is interrupted and a combustion system is returned to a system in which the combustion system is adapted for an engine operation state. SOLUTION: An electronic control unit(ECU) 60 of engine 10 stepwise switches over lean burn such as stratified charge combustion, weak stratified charge combustion, uniform lean combustion to an uniform rich combustion, and carries out a stepwise switching over process (rich spike process) in which the uniform lean combustion is switched over to a combustion system which is adapted for an engine operation state. When the engine operation state is deviated from a predetermined operation region, the ECU 60 stops the rich spike process and stepwise switches over the combustion system to a system which is adapted for the engine operation state. In the course of the switching over operation, the ECU 60 sets a combustion system maintaining period for maintaining the same combustion system longer than the combustion system maintaining period during the rich spike process.
