Inventor: OTSUKA HIROYUKI
IPC: H04B3/06
Filed: 1989-06-07
Abstract: PURPOSE:To improve the synchronization pull-in characteristic, the response characteristic and the convergence characteristic by employing the MLE constitution method in which the multiplication is implemented by taking the level of a signal and an error signal into account and the input signal of an adder circuit for integration is made zero, detecting inter-code interference quantity so as to vary the level of a multiplication output inputted to the adder circuit for integration. CONSTITUTION:The correlation between an error signal and an identification signal including not only the polarity (direction) but also the level is detected. Then a variable amplitude circuit 37 comprising an error quantity detection circuit 39 and a bit changeover device 38 has a function varying the result of multiplication in response to the level of the error signal, and increases the amplitude of the result of multiplication to output a large control signal thereby increasing the control variable of a transversal filter when the error quantity is large and decreases the control variable conversely when the error quantity is small. Moreover, the MLE method making an input signal to adder circuits for integration 34-36 zero is employed together. Thus, the synchronization pull-in characteristic, the response characteristic and the convergence characteristic are improved.

Title: Diffusion method for impurity
Inventor: TSUBONE HITOSHI
IPC: H01L21/22
Filed: 1977-12-07
Abstract: PURPOSE: To reduce the bending of the semiconductor substrate, by removing the oxide film of grid line before gold diffusion, in the process diffusing gold on the silicon substrate as impurity.  
     CONSTITUTION: The thermal oxide film SiO 2  2 is formed on the both sides of the silicon substrate 1. Next, the grid line 3 is formed for dice separation by performing etching SiO 2  film. The oxide film of the part of the grid line 3 is completely removed and the SiO 2  film at the back of the substrate 1 is simultaneously removed in forming the grid line 3. Further, gold 4 is evaporated on the entire rear surface of the substrate 1, and gold diffusion is made by holding the substrate under N 2  gas atmosphere at 1000 to 1200°C for 10 to 40 minutes. So as not to avoid the separation of gold again on the silicon substrate surface, the silicon substrate is picked up and rapidly cooled quickly from the diffusion furnace. At rapid cooling, since the stress caused due to the difference of the thermal expansion rate between the substrate and the SiO 2  film can be absorbed in the dice, the bending of the semiconductor substrate can entirely be reduced.

Title: Method for rolling down width of slab
Inventor: TAZOE NOBUHIRO
IPC: B21B15/00
Filed: 1990-06-05
Abstract: PURPOSE:To prevent only both end parts in a width direction of the rear end of a slab from showing an expanded sectional shape and to prevent a tang from being generated even in time of horizontal rolling in a succeeding stage by pressing the rear end of the slab in the width direction with a die having a large angle on a tapered part. CONSTITUTION:When a width is pressed with a die 15 having a large angle theta2 on the tapered part 5 only to the rear end 11 of the slab 1, a contact length between the tapered part 5 and the slab 1 is reduced by the size to the angle theta2 of the tapered part 5, the squeezed state of the rear end 11 of the slab 1 is more abrupt than that of the front end, the variation of the thickness of the slab 1 is difficult to reach the central part in the width direction, as a result, the rear end 11 of the slab 1 pressed in the with direction shows a dog bone shaped section in which only both end parts are expanded. Consequently, when the slab 1 is rolled horizontally in a succeeding stage, both end parts in the width direction 10 are extended more large than the central part at the rear end 11 of the slab 1, the tang is difficult to generate.
