Title: Production of grain oriented silicon steel sheet excellent in core loss characteristic
Inventor: IGUCHI MASAO
IPC: C21D8/12
Filed: 1999-03-11
Abstract: PROBLEM TO BE SOLVED: To moreover reduce core loss by subjecting the surface of a steel sheet to etching treatment while being applied with tension and thereafter forming a tensile insulating coating film thereon in accordance with an ordinary method. SOLUTION: When a silicon steel sheet is subjected to etching while being applied with suitable tension, not only the film thickness of a forsterite coating film is made thin, but also a suitable amt. of strain is introduced into the boundary between the coating film and ferrite. As a result that this strain is rapidly released by high temp. heat treatment at the time of the succeeding tensile insulating coating film formation, its magnetic properties such as core loss are improved. The etching treating solns. are particularly suitably composed of inorganic acid and SiCl4, and they may be used alone or in combination. In the case SiCl4 is used, its concn. in an aq. soln. is preferably controlled to 1 to 20 vol.%.  Furthermore, as to the size of the tension to be applied at the time of the etching treatment, in the case the applied tension is defined as T (kgf/mm2) and the thickness of the silicon steel sheet is defined as (t) (mm), the value of T/t is preferably controlled to the range of 5 to 20.

IPC: H01S5/30
Filed: 1993-03-01
Abstract: PURPOSE:To provide a gain combined distributed feedback semiconductor laser which performs single mode operation by gain combination and a method for the manufacture thereof wherein the manufacture of such semiconductor laser is facilitated; a re-growth boundary can be located away from an active, layer, and the recombination current is minimized at the re-growth boundary; and a quantum well structure can be used for the active layer, and the degree of freedom in designing is increased. CONSTITUTION:If impurities of a IV-group element, such as Si, is used in epitaxial growth on a cyclic shape 109 enclosed by planes 110, 111 and 112 having a different index, both of the p and n conductivity types are obtained depending on the orientation of growth plane. The above-mentioned phenomena is taken advantage of. A layer 114 and 115 where a first and a second conductivity types are alternately placed, is formed in proximity to an active layer 105. Using the resultant layer as an injected current narrowing layer 113, a current is unevenly injected to the active layer 105 to obtain the cyclic structure of gain. This obtains a distributed feedback laser structure which performs gain combination operation.

Filed: 1996-03-22
Abstract: PROBLEM TO BE SOLVED: To restrict telephone charge and to improve caller identification by permitting a transmission path to be one channel and transmitting the sound collecting signals of respective microphones after mixing. SOLUTION: Caller position data *1 obtained by detecting a caller position from a voice input to the microphone 1 by a caller position data detecting circuit 2 is multiplexed in a caller position information multiplexing circuit 4 together with voice data *2 obtained by executing digital conversion by a voice CODEC 3 and transmitted with a line interface circuit 5. A caller position information separating circuit 6 receives it and separates it into caller position and voice data #1 and 2. A caller position reproducing circuit 8 calculates the reproduction level of a voice signal analog-converted by the voice CODEC in respective speakers 9 from data #1 so as to output it.  Thus, the voice signal and caller position data are multiplexed in the 1-CH transmission path and a voice signal transmitting speaker level is decided at a reception side based on data #1 so that sound creep passage between the speaker and the microphone with the multi-CH transmission conversion of the voice signal is not increased.

Abstract: PURPOSE:To prevent demodulation error of data by comparing two correlation outputs on a reception side and assigning 0 or 1 of received data according to the comparison result. CONSTITUTION:A Manchester code M sequence which is generated by one Manchester M sequence generator 31 is set in one correlator 21 and the correlation between the set sequence and a received signal RXI is found; and a Manchester code M sequence which is generated by the other Manchester M sequence generator 32 is set in the other correlator 22 and the correlation between the set sequence and received signal RXI is found.

Filed: 1992-03-24
Abstract: PURPOSE:To enable the stable selection of wavelengths even if a transmission peak wavelength band changes by controlling the voltage to be impressed to the transparent electrode of a liquid crystal variable wavelength filter so as to maximize the electric signal from a photodetector. CONSTITUTION:The transmission band of the transmitted light passing the liquid crystal variable wavelength filter 2 changes according to the voltage impressed to the transparent electrode of the liquid crystal variable wavelength filter 2.

The such feedback control is executed, by which the max. output light is obtd. at all times from the liquid crystal variable wavelength filter 2. Then, even if a fluctuation arises in the transmission peak wavelength according to temp., the impressed voltages changes according to this fluctuation value and the transmission peak wavelength is regulated.
