Title: Fm modulator
Inventor: FUSE MASARU
IPC: H04B10/548
Filed: 1997-08-28
Abstract: PROBLEM TO BE SOLVED: To provide an FM modulator in which the carrier to noise power ratio is furthermore improved. SOLUTION: A branching section 101 branches a received electric signal into an in-phase signal and an opposite-phase signal whose phases are inverted to each other. A 1st FM laser 104 converts the in-phase signal into an optical frequency modulation signal (1st optical signal) with a center wavelength of Al and provides an output. A 2nd FM laser 105 converts the opposite-phase signal into an optical frequency modulation signal (2nd optical signal) with a center wavelength of λ2 and provides an output. After the two optical signals are synthesized and the result is given to a photoelectric conversion section 106.  The photoelectric conversion section 106 applies optical heterodyne detection to a received optical signal by its square detection characteristic and provides an output of a beat signal of the two optical signals being broad band FM modulation signals at a frequency equivalent to a wavelength difference Δλof the 1st and 2nd optical signals (=|λ1-λ2|). Thus, a frequency shift of an outputted FM modulation signal is extended and the CNR is considerably improved.

Title: Reduction resistant dielectric ceramic composition and stacked ceramic capacitor using the composition
Inventor: NISHIMURA TSUTOMU
IPC: C04B35/46
Filed: 1992-09-01
Abstract: PURPOSE:To provide an effective ceramic composition for a ceramic capacitor by using BaTiO3 as a main component, and concurrently containing a composite oxide Ba(MeNb)O3 where Me stands for one or more of Mg, Co and Mn. CONSTITUTION:This reduction resistant dielectric ceramic composition contains a manganese oxide and, therefore, the change of BaTiO3 to a semiconductor phase due to baking under low oxygen partial pressure is restrained by charge compensation. As a result, the composition shows good insulation resistance even after a baking process under the low oxygen partial pressure. Also, Nb2O5 takes a form of a core shell structure, diffused on the surface of BaTiO3 particles at a baking process in the atmosphere. Consequently, a difference appears in the thermal characteristic of a dielectric constant between the inner portion of pure BaTiO3 and the surface portion of diffused Nb2O5, and the constant is smoothed as a whole. In this case, the composition is made into a composite perovskite compound of a Nb system and Nb2O5 is added thereto. Then, Nb and other metals are together added to the B site of the perovskite, thereby generating quadrivalent state. Consequently, when an inner nickel electrode is baked in low oxygen atmosphere, the thermal characteristic thereof can be smoothed without any loss of reduction resistance, regardless of contained Nb2O5.

A video data storing part 3 holds the identifica tion data of the rays passing through the picture element at every picture element in the screen set at the time of generating the three-dimensional video from the crossing object. A comparing part 4 successively comapres the identification data of the two adjecent picture elements out of the identification data, and when the two identification data are different, a boundary line extracting part 5 sets the specific luminance value at either one of the picture element. Further, the boundary lines between the objects and the surfaces are extracted, and the projection drawing is preapared. Thus, the projection drdawing of the three- dimensional object can be promptly and easily prepared by the ray tracing method.
