Title: Adaptive type digital filter
Inventor: ITO YOSHIO
IPC: H03H21/00
Filed: 1986-04-30
Abstract: PURPOSE:To reduce the operation processing quantity, the circuit scale and the power consumption and to quicken the convergence by connecting a specific (N-1)-th order noncyclic digital filter in cascasde with a specific N-th order cyclic digital filter. CONSTITUTION:An input signal x(k) to an adaptive digital filter (ADF) 3 and a signal b.phi(k-N) being the result of multiplication of a coefficient (b) with a signal phi(k-N) by a multiplier 7 are added by an adder 6 to form a signal phi(k) at a time (k). The signal phi(k) inputted to a unit delay element 8-1 at the time (k) is being sequentially retarded via unit delay elements 8-1-8-N as the time (k) elapses. Further, the inputs phi(k)-phi(k-N+1) to each delay element at the time (k) are subject to multiple of a0-aN-1 by multipliers 9-0-9-(N-1), respectively, the result is added by an adder 10 to form an output y(k) of an ADF 3. Since the coefficient (b) and the factors a0-aN-1 are subject to adaptive control, the pole of the transfer function of the ADF is well matched with the pole of the transfer function of an actual acoustic coupling part and the input signal to the factors a0-aN-1 is made orthogonal, respectively, then the circuit scale is reduced remarkably and the converging speed is quickened.

Title: Bipolar transistor, manufacture thereof, and electronic circuit device or optical communication system using the same
Inventor: ODA KATSUYA
IPC: H01L31/10
Filed: 1999-04-06
Abstract: PROBLEM TO BE SOLVED: To enable high-speed operation for a bipolar transistor by lowering the external base resistance and lessen the dispersion of base resistance, and making the capacity between a collector and a base small. SOLUTION: A single crystalline Si-Ge intrinsic base 18 and a base layer 7 are connected with each other in a self alignment manner, by thickening a low-concentration collector layer 16 in the vicinity of an external base layer. Hereby, the distance between the intrinsic base 18 and the base lead layer 7 is reduced, and junction region is increased, whereby the base resistance of the splicing section can be reduced, and the dispersion of the base resistance can be reduced. Since the low-concentration collector becomes thick in the vicinity, the capacity between the collector and the base decreases. Accordingly, a high-speed bipolar transistor can be materialized, and by using this, an electronic circuit device or a system capable of high-speed operation can be materialized.

Abstract: PURPOSE:To prevent the scattering of toner from a space and the infiltration of foreign matter into a developing machine, and to improve the reliability of a printer by providing a magnetic member between the sidewall of the developing machine and the end part of a developing roll, and on both end parts of a napping regulating member, and blocking the space formed in the nonmagnetic range of the sidewall of the developing machine and the end part of the developing roll with magnetic powder. CONSTITUTION:A planar magnetic member 15 thinner than a distance between the developing roll 9 and a sidewall 17 is attached around the developing roll 9 except the outside of both end parts of the napping regulating member 8 and a notched part for taking out the developing roll 9 of the sidewall 17. Therefore, when the developing roll 9 is driven, the developer is uniformized to obtain a constant thickness by the napping regulating member 8. The developer is infiltrated outside the magnetizing range of the end part of the developing roll 9, as well. A part of a magnetic ferrite carrier in the infiltrated developer is attracted to the planar magnetic member 15 provided on both ends of the napping regulating member 8 and the sidewall 17, and the space is blocked. On the other hand, even if the developing roll 9 is rotated at high speed, the planar magnetic member 15 can not be shaved. Thus, the failures of the occurrence of the scattering of the toner and the infiltration of the foreign matter into the developing machine are improved, and the reliability of the printer can be improved, as well.

Title: Light pulse compressing device and method therefor, signal transmitting device and method therefor
Inventor: MASUDA SHIN
IPC: H01S3/121
Filed: 1998-04-10
Abstract: PROBLEM TO BE SOLVED: To allow a light pulse which is pulse compressed and is not spatially dispersed output in a desired position with a small-sized structure by which the number of dispersed devices is not increased. SOLUTION: Light pulse is pulse-compressed by first and second dispersing devices 211 and 212 and reflected by a light reflecting device 411 for feedback. Light pulse output from the first dispersing device 211 is separated by a light beam separating device 412. The pulse-compressed light pulse in the first and second dispersing device 211 and 212 are dispersed spatially also. Its optical axis is transferred from an input light path. If the light pulse is reflected by the light beam reflecting device 311 and is brought back, the spatial dispersion of light pulse is released and the light intensity distribution becomes identical to that of the initial state and the optical path coincides with the input optical path. Since the light pulse is separated from the input light source, a light pulse which is pulse-compressed but is not dispersed spatially made to exit to a desired position.
