IPC: H03F1/42
Filed: 1993-07-13
Abstract: PURPOSE:To provide a stable operational amplifier circuit in which a phase margin is not changed even when a load capacity is changed by impressing the same input signal to the gate of a transistor connected with a constant voltage, and an input differential pair. CONSTITUTION:Signals impressed to input terminals 4 and 5 are respectively inverted by transistors TrM3 and M4 constituting a differential pair 3, amplified by TrM1 and M2, and outputted from output terminals 6 and 7. Also, the signals impressed to the input terminals 4 and 5 are directly impressed to the gates of the TrM1 and M2, inverted and amplified, superimposed on the signals transmitted through the TrM3 and M1 and the TrM4 and M2, and outputted from the output terminals 6 and 7. That is, the operational amplifier circuit as a whole, differential voltages impressed between the input terminals 4 and 5 is inverted and amplified, and outputted as the differential voltages between the output terminals 6 and 7. Thus, the stable operational amplifier circuit in which the phase margin is not affected by the change of the load capacity can be obtained.

CONSTITUTION:The substrate 1 made of stainless steel is fully purified and immersed in an Ni plating bath having a composition of NiCl2 6H2O, NH4Cl, (NH4)2 HC6H5O7, NaH2PO2 and NH4OH. In this way, electroless Ni plating is applied and thereby an Ni layer 11 conraining P is formed on the surface of the substrate 1. Next, by glow-discharge decomposition or any other methods, the amorphous Si layer such as i-type layer 22 and P<-> type layer 23 is piled on the layer 11 and a collector-electrode 4 is fitted thereto through the intermediary of a transparent electrode layer 3. By this composition, the P in the layer 11 is diffused up to the part 24 of the layer 22 in piling and thereby excellent ohmic contact is generated between the substrate 1 and the layer 22. When this is used for the solar cell, the photoelectric conversion efficiency thereof is improved by about 50% as compared with the conventional cells.

Title: Reproducing device and reproducing method
Inventor: INOUE TAKAO
IPC: H04N5/783
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To obtain a high quality down-converted image from a slow motion reproduction image or a reproduced image by slow motion reproduction. SOLUTION: Reproduction field information and output field information of a reproduced HDTV signal are fed to a down-converter 9 that converts an HDTV signal into an SDTV signal. The converter 9 conducts field conversion processing based on the combination of the information sets. In the case of slow reproduction, a signal of an identical field is received twice. There are four patterns in the case that input/output fields are coincident or dissident, and interpolation processing is required for parts of the patterns. It is determined which one of 4-pattern processings is required, based on the reproduction field information and the output field information. In the case of conventional reproduction, only two patterns where input/output fields are coincident are used among the 4 patterns. Slow reproduction processing and down-convert processing are conducted altogether by field conversion and interpolation processing attended therewith.
