IPC: H03M1/76
Filed: 1988-08-08
Abstract: PURPOSE:To generate a reference voltage with a few circuits by providing a means applying voltage division by resistors twice and correcting an error caused at the voltage division. CONSTITUTION:Resistors R1-R4 are connected in series, one terminal is connected to a power potential and the other terminal is connected to ground level. A selection circuit 1 receives potentials from connecting points A to D, selects one potential by using selection signals S2, S3 and the result is outputted. A selection circuit 2 receives potentials from connecting points B to E, selects one potential by using selection signals S0, S1 and the result is outputted. One terminal of resistors R11-R14 is supplied to the output of the selection circuit 1 and the other terminal is connected to the output of the selection circuit 2. A selection circuit 3 selects potentials from connecting points F to I by using the signals S0, S1 to output an analog voltage V0. The value of correction resistors R21-R24 is equal to the series combined resistance of the resistors R11-R14, switches SW1-SW4 are controlled by using the signals S2, S3 to correct the voltage division correctly. Through the constitution above, number of resistors to obtain voltages of 16 steps, for example, is enough to be 12, the circuit is realized by using 3 sets of 4-input selection circuits and 4 switches, then the scale of the circuit is much reduced.

Title: Semiconductor integrated circuit device
Inventor: ONOZAWA KAZUNORI
IPC: H01L29/73
Filed: 1990-07-26
Abstract: PURPOSE:To improve the title device in cut-off frequency as well as the junction breakdown strength of a bipolar transistor having vertical type structure by setting the peak of the impurity concentration of the well region of the collector region of the bipolar transistor having vertical type structure in the joining section of an emitter region and a base region or the base region deeper than the joining section. CONSTITUTION:In the region of a bipolar transistor Tr, the maximum peak of the impurity concentration of an N-type well region 5 is set at a slightly deeper position in the substantially same manner as the N-type well region 5 of the region of a P channel MISFET QP. To be concrete, the maximum peak of the impurity concentration of the N-type well region 5 is set to the joining section of an N<+> type semiconductor region 22 as an N-type emitter region and a P-type semiconductor region 9 as a P-type base region or into the P-type base region deeper than the joining section, the inside of the P-type semiconductor region 9. The N-type well region 5 increase the concentration of the N-type impurity of an intrinsic collector region just under the p-type base region of the bipolar transistor Tr. A section, in which the concentration of the N-type impurity of the intrinsic collector region is elevated, corresponds to a region in which an effective base region is spread on large current operation. Accordingly, junction breakdown strength is improved and the device is improved in cut-off frequency.

Title: Production of optical fiber preform doped with rare earth element and production of optical fiber doped with rare earth element
Inventor: IMOTO KATSUYUKI
IPC: C03C13/04
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To provide a process for the production of an optical fiber preform doped with a rare earth element and having low transmission loss without causing cracking and breakage and provide a process for the production of an optical fiber doped with a rare earth element. SOLUTION: An Er-doped SiO2 -GeO2 -Al2 O3 layer and an SiO2 layer are formed successively on the inner wall surface of a quartz pipe, an Er-doped SiO2 -GeO2 -Al2 O3 glass rod is inserted into the quartz pipe, the quartz pipe is welded to the glass rod by heating the pipe from outside with an oxyhydrogen burner and the product is collapsed to form a solid optical fiber preform. Since the difference between the softening temperature of the glass rod for forming the core of the optical fiber preform and that of the quartz pipe for forming the outer sheath of the preform and the difference of the thermal expansion coefficients of both members are decreased by this process, the generation of crack and breakage can be suppressed to prevent the lowering of reproducibility and yield.  Since the process contains decreased number of steps to convert the preform to transparent glass, the variation of the refractive index distribution in the optical fiber preform is decreased and the problems of breakage and cracking can be eliminated.

Filed: 1987-08-07
Abstract: PURPOSE:To prevent the destruction or latchup of an element due to an excess current by providing a ring oscillator circuit, a count circuit counting the output pulse number of the ring oscillator circuit and a means keeping a part of the internal circuit to a constant state independently of an external signal till the count reaches a prescribed value after power application. CONSTITUTION:The ring oscillation circuit 4 starts its oscillation at an inherent oscillation frequency at the application of power. The counting circuit 5 keeps the signal output (6) to a 1st potential for a period when the output pulse number of the ring oscillation circuit 4 reaches a prescribed value or over. Thus, an external signal operating circuit 2b is kept to a prescribed state independently of the external signal. When the output pulse number of the ring oscillation circuit 4 reaches a prescribed value, a signal line 6 reaches a 2nd potential and the circuit 2b is operated by the external signal. Thus, since the internal circuit is kept to be in a prescribed state independently of the external signal till the transient state of the circuit inside is converged after the application of power for example or a sufficient substrate potential is obtained, the destruction or latchup of the element, etc., due to excess current is prevented.
