Title: Manufacture of substrate for discrete circuit
Inventor: SATO TSUTOMU
IPC: C30B33/00
Filed: 1998-03-26
Abstract: PROBLEM TO BE SOLVED: To flexibly conform the dislocation density to a required level by lapping a silicon semiconductor wafer for specifying the thickness of the material wafer before diffusion, and then conducting a diffusion in proper area of the wafer to obtain a substrate for discrete circuit of a two-layer structure. SOLUTION: This is a method for manufacturing a silicon semiconductor substrate for discrete mounting of a two-layer structure having a diffused layer (Xj) on one side and an undiffused layer (Xi) on the opposite side of a silicon semiconductor wafer, with the mean dislocation density on the surface of the undiffused layer is 5,000/cm<2> or below. Here the wafer is lapped and so pretreated that a processing distortion at the time of lapping remains. The thickness of the material wafer is expressed by a formula T=2Xj+Xi+α, where 'α' is the margin for adjustment for determining the thickness of the material wafer and is set such that 45<=α<=930. The exact value for α is determined according to the dislocation density required on the surface of the undiffused layer in the substrate for discrete mounting.  After the value of αhas been determined and the material wafer has been adjusted to a thickness specified by the formula, diffusion is conducted.

IPC: H03H19/00
Filed: 1991-04-11
Abstract: PURPOSE:To easily adjust a post filter circuit, and to reduce the power consumption of a switched capacitor filter(SCF) at a main body side. CONSTITUTION:When the outputs of a first SCF to change at 336kHz sampling are inputted from an input terminal 1, these are fetched alternately at clocks phi1, phi2. At the time of phi1=H, capacitors 11 to 17 are charged simultaneously, and at the time of phi2=H, the capacitors 39 to 45 are charged simultaneously. Since the capacitance values of these above-mentioned two groups of the capacitors are weighted by the impulse response of a non-recursive filter for primary interpolation, a 1,344MHz sample signal in the case of the primary interpolation of 336kHz sampling input can be calculated successively by adding these charges by an operational amplifier 60 at the clocks phi9, phi10 while taking out them successively at the clocks to phi1 to phi8.

Title: Register controlling system
Inventor: ONO YOSHIHARU
IPC: G06F9/38
Filed: 1985-04-15
Abstract: PURPOSE:To quicken a start of execution of a branch destination instruction by executing a control so that a precedence store is inhibited even if execution of an index register store instruction is started, when a conditional instruction displaying circuit is in a set state. CONSTITUTION:A decoder 10 decodes an instruction code, and supplies a result of this decoding to the first control circuit 11. Then, in case a condition branch instruction TZE precedes index register store instructions EAX 1, EAX 2, a conditional instruction displaying circuit in the circuit 11 becomes a set state between timings t1-t3, therefore, the circuit 11 stops outputting a control signal for instructing write to the second index register group 4. When a precedence store to the register group 4 is inhibited in this way, even if the instruction TZE is executed in an executing state E and made to branch to a load instruction LDA, it will suffice by only cancelling a result being on the way of execution of the instructions EXA 1, EXA 2, LDA, etc. which follow the instruction TZE, by a write stage W of the instruction TZE, and a release of registers X1, X2 becomes unnecessary.

Abstract: PURPOSE:To realize to shorten the training period of an automatic equalizer by means of a relatively simple circuit by detecting that a coefficient correction signal becomes an iteration signal of reversed polarity, which increases and decreases the coefficient, when correcting each tap coefficient. CONSTITUTION:A correction signal B for the first tap coefficient becomes, after the convergence of the first tap coefficient, an interation signal which has reversed polarity of 1-0-1-... at the time of coefficient correction. The phase of the iteration signal of 1-0-1 or 0-1-0 is shifted by a D-FFD11 and D12 and the outputs of the FFD11 and D12 are ANDed by exclusive OR circuits EOR11 and EOR12, and they are outputted from an AND gate AND11 to obtain a signal for discrimination of convergence of the first tap coefficient. In the same manner, signals for discrimination of coefficient convergence of the second-n-th taps are obtained. Discrimination signals of all taps are inputted to an AND gate AND2, and the output of it is inputted to a D-FFD. From the D-FFD, a equalizing discrimination signal F is obtained. As a result, the convergence of each tap coefficient is automatically detected.
