Title: Video signal level processing circuit
Inventor: MUKODA YUKINORI
IPC: H04N5/14
Filed: 1992-04-30
Abstract: PURPOSE:To reduce errors by considering a maximum input value, an arithmetic processable level, and the maximum value of quantized bits for the signal level of the video signals and converting in level to make the weight of LSB smaller. CONSTITUTION:Digital input signals 1 detect the maximum level within one line by a level detecting 3 and transmit control signals to a level adjuster 5. The respective input signals are multiplied by ratios corresponding to the control signals. Calculation performed by matrix, arithmetic processing, and inverse matrix is considered beforehand, and the several kinds of the ratios of which the maximum values are the maximum of the quantized level are prepared. The respective kinds of the arithmetic processing for picture processing are performed, for example, by a matrix computing element 6, arithmetic processing circuit 7, and reverse matrix computing element 8, and the reciprocal the ratios multipled by the adjuster 5 are multiplied at a level demodulator 9. The, synchronized signals are added from a synchronous separation 4 through a timing adjusting 10 by a synchronous synthesis 11, the original signal array is returned, and output signals 12 are obtained. Thus, the digital calculation errors in the whole picture processing circuit are suppressed smaller even when the arithmetic processing is performed with less quantized bit numbers.

Abstract: PURPOSE:To enable the combustion of an engine to be smoothly transferred, by starting supply of dispersed fuel if a load reaches the second preset level and decreasing supply of stratifying fuel if the load further increases to reach the first preset level so as to transfer the combustion to uniform combustion. CONSTITUTION:When a supply amount of fuel is controlled, a control means 16, in its range of low and intermediate loads below the first preset level by a load detecting means 17, stops supply of dispersed fuel by a fuel supply means 13, places a throttle valve 14 in its full opening condition so as to hold an intake air amount in a fixed level and supplies stratified fuel in accordance with the load from a fuel supply means 11, performing stratified combustion with a large rate of excess air. Next, the control means 16 starts the supply of the dispersed fuel by the means 13 if the load increases to reach the second preset level, and decreases the stratified fuel while increases a supply amount of the dispersing fuel so that the total amount of supply fuel may meet the load if it further increases to reach the first preset level, thus transferring the combustion from the stratified combustion to uniform combustion. In this way, both the improvement of fuel consumption and the smooth transfer from the stratified combustion to the uniform combustion can be attained.

Next with this as a mask, etching is performed to etch electrode lead-out holes 5 on the region 3 while producing overhangs in the pattern 6. With the pattern 6 being left, a polycrystalline Si layer 7 is deposited over the entire surface. Then the layer 7 becomes discontinuous and therefore if the pattern 6 is removed together with the layer 7 thereon, the layer 7 remains only in the holes 5 through self-alignment. Thereafter, Al is deposited selectively here and heat treatment is performed to form ohmic contact, whereby the specified wiring patterns are obtained.
