Title: Signal integrator
Inventor: SAUER DONALD JOHN
IPC: G06G7/186
Filed: 1988-12-22
Abstract: PURPOSE: To prevent the linearity of the signal integrator from decreasing by delaying a 1st control signal behind a 2nd control signal and blocking a signal relating to the transition of the 1st control signal from being coupled with the input terminal of an amplifier. CONSTITUTION: Clock signals P2D and P2DN which control transmission gates T1 and T5 are about 5ns delayed behind clock signals P2 and P2N. Then transmission gates T2-T4 conduct at the same time in a period of a 1st part of each cycle of, for example, a clock P1 to discharge capacitors C1 and C2. Then the transmission gates T2-T4 turn off and the transmission gates T1, T5, and T6 turn on. The transmission gate T6 which is controlled with the clock signals P2 and P2N is turned off about 5ns before the transmission gates T1 and T5 are turned off, so the transmission of net electric charges at, for example, the transmission gate T1 exerts no influence on a signal out through the operation of the transmission gate T6 which is already turned off at this time.

Filed: 1998-11-17
Abstract: PROBLEM TO BE SOLVED: To easily recognize an audio state even at time of silence by storing the volume value of an amplifier as a target value, when power is turned off previous time, reading the target value when power is turned on at this time, increasing the volume value from a prescribed value around zero and energizing an audio signal generation circuit and a feedback sound generation circuit. SOLUTION: A control part 1 reads a volume value from a memory 2, when power is turned off at previous time with the turning on of power, sets a target value and controls the volume value against a preamplifier part 6 to zero or to the prescribed value, which is substantially zero and compares the present volume value with the target value. Since the present value is smaller than the target value at first, a feedback sound generating circuit 5 is energized, a feedback sound is rung once and the volume value is increased by one stage. The operation is repeated and the volume value is fixed in the case that the present value is equal to or larger than the target value. An audio signal is reproduced, and the feedback sound generation circuit 5 is de-energized.

Abstract: PURPOSE: To form a wrapped trench isolating structure which does not have the limit and defect of known method and can allow the use of ordinary types of material and device by forming a trench having a round bottom section into a semiconductor silicon substrate by forming a wrapped trench isolating structure into the semiconductor substrate. CONSTITUTION: A semiconductor silicon substrate 1 is etched to a sufficient depth. As a result, the relative undercut of a taper-like remaining section 5' of silicon oxide substantially isotropically intrudes into the substrate 1 until an isolating area substantially reaches the bottom end of a vertical wall surface formed by the preceding limited etching through an oxide layer 4, a nitride layer 3, and a PAD oxide layer 2 below the base section of the remaining section 5'. Therefor, a trench having a desired round shape can be formed. After the trench is formed, an insulating material layer 7 is adhered to the substrate 1 until the trench formed into the substrate 1 is completely filled up with the layer 7.  Therefore, a wrapped trench isolating structure which does not have the limit and defect of the already-known method and can allow the use of ordinary types of material and device can be formed.

Subsequently, after the aging-heat-treatment, the wire 3, the outer diameter of which is 0.8mm and on which the lubricant 4 is applied, is inserted into the hole 5 again, followed by cold drawing process. After that, the wire 3 is extracted to provide a sleeve type superconductor such that its outer diameter is 2.0mm, the bore diameter of the hole 5 is 0.6mm, its copper ratio 4.1, and its length 20cm. Accordingly, the uniformity of quality can be attained by eliminating variations in its outer diameter or the like, at the same time a cold drawing process and an aging-heat-treatment can be performed. Thus, the wire 3 is prevented from not being extracted from the hole 5, so that workability and productivity can be enhanced resulting in cost cut.
