Filed: 1989-09-13
Abstract: PURPOSE:To reduce the area of a memory IC and the propagation delay by a method wherein a plurality of fundamental cells are arranged in an array shape and through holes for connection between word lines or single-crystal semiconductor layers and metal interconnections are formed in parts whose number is smaller than that of memory cells. CONSTITUTION:Fundamental cells 111 constituting memory cells are arranged in an array shape; through-hole cells 21 are formed at a rate of one piece for (n) pieces of cells 111; metal interconnections of bit-lines BIT and the inverse of BIT are formed in arbitrary interconnection layers. Word lines W' are formed in parallel with metal interconnections l'' on interconnections of a control electrode material for a switching element 2 and in interconnection layers which are different from bit lines. The interconnections W' by the control electrode material for the element 2 and the interconnections l'' are connected through holes 121 of the cells 21; also power-supply lines 22 of a diffusion layer are connected via the interconnections l'' and through holes 122. Consequently, the through holes are omitted sharply; the area of an IC can be reduced; the metal interconnections are connected in parallel; the propagation delay of a signal or the like can be reduced to a minimum.

Title: Optical fiber for amplification use
Inventor: KAWAMURA TATSUHIRO
IPC: H01S3/10
Filed: 1996-09-09
Abstract: PROBLEM TO BE SOLVED: To reduce the gain difference between wavelengths of each light signal and also to enhanced conversion efficiency from the input of stimulation light to the output of the light signal in an optical amplifier by a method wherein La is doped to the interior of a core or the outer peripheral part of the core along with Er and Al and at the same time, each optical fiber for amplification use is set so as to have concentration redundant product, at which the gain differences between wavelengths of the light signals of each wavelength become smallest. SOLUTION: In the case where the light signal of a multiplexed wavelength is batch- amplified, the value of a concentration redundant product (CL), at which an gain difference between wavelengths of each light signal becomes smallest, exists in any optical fiber for amplification use regardless of the presence or absence of a boding of La. The gain differences between wavelengths of the respective light signal, become smallest at the places of a density redundant product CL1 =10.8kppm.m and a density redundant product CL2 =12.2kppm.m, which correspond to the position of the intersecting point of two broken lines, and moreover, in the respective gains of the optical fibers for amplification use, the gain of the optical fiber for amplification use, which is doped the La(lanthanum) along with Er and Al, is large.  Accordingly, if the density redundant products of the optical fibers are previously set so as to become the optimum concentration redundant product (CL), the intensities of the wavelengths of the light signals become roughly the same intensity, the gain differences between wavelengths of the light signals are reduced and gain wavelength characteristics are obtained. As a result, a conversion efficiency from the input of excitation light to the output of the light signal in an optical amplifier can be enhanced.

Title: Digital pll circuit
Inventor: KUWATA KOSUKE
IPC: H03L7/06
Filed: 1990-09-07
Abstract: PURPOSE:To control a count period without changing a counter clock itself by oscillating a basic clock from an oscillator and allowing a control circuit to output a control signal in response to a phase difference between an input signal and an output signal of a digital VCO. CONSTITUTION:For example, a phase of an input signal Fin is lagged than a phase of an output signal Fout, then a control circuit 12 outputs a control signal STOP to correct a phase difference between the input signal Fin and the output signal Fout. In this case, a count of a counter 14 when the control signal STOP is generated is zero and it is outputted as data D1-D4 together with a load signal LO. As a result, the said count remains logical 0 for two periods of a basic clock signal CLK and the count operation is act like as if it were stopped for that time. Thus, the count period is increased by one pulse of the basic clock signal CLK thereby increasing the period of the output signal Fout.

IPC: H03G3/20
Filed: 1991-06-13
Abstract: PURPOSE:To obtain a radio receiver corresponding to a strong electric field by increasing the attenuating effect of an antenna input signal. CONSTITUTION:When the electric field intensity of the antenna input signal is increased, the AGC voltage for pin diode driving outputted from the gain control circuit 13 of an FM front end IC 14 is increased. Therefore, an attenuating circuit 5 is driven, and the impedance of the circuit is deteriorated, and a signal inputted to the antenna input terminal receivers attenuation corresponding to the impedance ratio between the attenuating circuit 5 and an antenna input capacitor C3, and a part of the antenna input signal is inputted to an antenna circuit 1 to be subjected resonance expansion. The output receives the attenuation corresponding to the impedance ratio between the attenuating circuit 5 and a first capacitor C1 on the circuit 1 and is inputted to the first gate g1 of a high frequency amplifier element 4. Further, when the antenna input signal is strong, the AGC voltage becomes higher so that the impedance of the antteunating circuit 5 approaches to zero and almost antenna input signals are attenuated. Since the desired adjacent ratio wave is remarkably attenuate, as well, the interference radio wave counter measurement can be performed even without the degree of the selection of the antenna turing circuit 1.
