Filed: 1989-03-28
Abstract: PURPOSE:To eliminate the rate determining part of breakdown strength for increasing the breakdown strength and the current capacity by a method wherein, within a MOSFET having gates in curved shape, the channel concentration and the effective channel length of the channel diffused regions are equalized. CONSTITUTION:The channel diffusion process in the dual diffusion process using gates 7 as mask does not form the whole channel diffusion regions 3a, 3b in a single diffusion process but approximates to the regions 3a, 3b using a curvature circle forming the gate edge; separate diffusion processes are performed for the segments in different curvature; furthermore, the impurity in the quantity monotonously decreasing down to curvature of applicable segment is diffused in respective diffusion processes. That is, the impurity concentration and the effective channel length l1/l2 are evenly equalized in either part of the channel diffusion regions 3a, 3b. Through these procedures, the effective channel regions C1, C2 have no rate determining part of breakdown strength, the depletion layer spreads evenly to increase the breakdown strength while the current runs evenly in the effective channel regions C1, C2 so that the saturated current may be augmented to increase the current capacity.

IPC: G05B13/04
Filed: 1986-04-04
Abstract: PURPOSE:To obtain a model normative adaptive control system that shows the satisfactory adaptive working by performing the switch of algorithms between a fixed target value signal and an unfixed one. CONSTITUTION:Both the operation input u1(k) and the controlled variable y(k) are supplied to a parameter estimating part 5 through a filter 6 which deletes the disturbance. Thus the part 5 estimates a parameter related to the dynamic characteristics of a controlled system 2 and furthermore controls the parameter of a controller 4 according to a fixed rule as well as the parameter theta. The controller 4 fetches the target value r(k), an output error (k) and the controlled variable y(k) and produces the manipulated variable u1(k). An integration element 3 which suppresses the disturbance is set into a closed loop formed by the controller 4 and the controlled system 2. Then the target value r(k) is fetched by a target value deciding part 7 and the changing degree of the value r(k) is decided there. The algorithm of the part 5 is changed in response to the result of decision of the part 7. At the same time, the filter 6 is replaced or the element 3 is actuated and stopped.

Filed: 1999-03-19
Abstract: PROBLEM TO BE SOLVED: To effectively utilize a memory by dividing the memory into an area for storing address information of relatively high reference frequency and an area for storing address information of relatively low reference frequency and dynamically varying the border between the areas. SOLUTION: The timer value of address information in an address table RAM 120 is reset to 0 each time the address information is referred to and moved to the HIGH area 201 when address information in the LOW area 202 is referred to. When address information is newly registered in the address table RAM 120, the timer value of the address information is set to 0 and registered in the HIGH area 201. Consequently, two address tables of the HIGH area 201 and LOW area 202 are present in the memory; and the address information of high reference frequency is registered in the HIGH area 201 and address information of low reference frequency is registered in the LOW area 202, thereby shortening the reference time of the address information of high reference frequency.

IPC: H04N5/262
Filed: 1978-06-24
Abstract: PURPOSE: To make it possible to obtain out-focus effect with a TV camera out of focus, by providing an address signal forming method and adding method.  
     CONSTITUTION: As a result of storing memory 3 with video signal S1 after A/D conversion, the memory content of address A(10,10) of memory 3 is supposed to be level "1". Since address signal A(n+1, m+1) among nine read address signals A r  becomes A(10,10) when reference address signal A 0  is A(9,9), output V9 of memory 3 becomes "1" and outputs V1 to V8 of other addresses "0". After being multiplied by a fixed number by multiplier 5, V1 to V9 are added together by adder 7 and the level of output S3 of adder 7 becomes 0.063. The lightness of a picture, therefore, increases 0.063 time. The picture, output S3 of the adder, increases in area 3×3 times the original picture and decreases in lightness at a fixed rate. Namely, nearly the same picture as the original picture with the camera out of focus can be obtained.
