Filed: 1996-06-05
Abstract: PROBLEM TO BE SOLVED: To achieve high speed processing while reducing power consumption significantly by performing a logical sum, a logical product or a composite operation thereof based on a tact that the tunneling to a lowest energy level is prohibited by the Pauli exclusion principle. SOLUTION: A logical sum, a logical product or a composite operation thereof can be performed by inputting electrons into an operational quantum box QD0 through irradiation of light, for example, and reading out the electron distribution in an array of quantum boxes QD1 , QD2 after the energy of electrons is relaxed. More specifically, presence/absence of an electron occupying the lowest energy level of the operational quantum box QD1 , QD2 is provided as bit information and a phenomenon that the operational quantum boxes are saturated sequentially starting from that having lowest energy level is utilized based on the fact that the tunneling to the lowest energy level is prohibited by the Pauli exclusion principle.  Since the energy being dissipated from an electron, i.e., the energy being consumed for the operation of 1 bit, is extremely low, a quantum operating element having extremely low power consumption is obtained.

IPC: H04N5/357
Filed: 1993-06-15
Abstract: PURPOSE:To obtain a color separation signal with high S/N by separating each color signal from a point sequential signal through the use of a delay element to reduce noise associated with sample-and-hold operation. CONSTITUTION:When a point sequential input signal vi0 in which color signals R0, G0, B0 are arranged serially timewise as an input signal is inputted to a color separation circuit, the signal vi0 is delayed at a delay element 1 by a tauand an output vi1 is provided. Furthermore, the output vi1 is delayed at a delay element 2 by a tau ad an output vi2 is provided. The delay time tau is selected to be equal to a period of each color signal. Then noise appearing after color separation generated in an amplifier circuit and included in point sequential signals vi1, vi2 obtained by delaying the signal vi0 is reduced to 1/3 of the circuit noise thereby reducing noise associated with sample-and-hold operation. Thus, noise power after color separation is small and the signal with excellent S/N is obtained.

Title: Electronic cooling low noise amplifier
Inventor: IWAKUNI MIKIO
IPC: H01L23/12
Filed: 1984-07-11
Abstract: PURPOSE:To prevent the temperature of an FMT chip from rising and to improve a cooling efficiency by setting up an electronic cooling device to cool a ceramic substrate directly. CONSTITUTION:An electrnic cooling device 25 in a triple module construction using a Peltier effect cools directly the back of a ceramic substrate 28 and diffuses heat taken throughout a case 27 through a radiating fin 26. As the ceramic substrate 28 with an amplification circuit 21 on it is directly cooled by the thermoelectric device 25, a heat capacity and a substrate area of a cooling part can be made far smaller than those of a conventional device. Heat flowing into a cooling part through an in-out terminal from the outside is shutoff by the ceramic substrate 28. Consequently a cooling capacity can be improved sharply. A much better effect can be obtained by mounting an FET chip on a mounting part, in which such a metal plate as copper is embedded, of an FET chip 29 of the ceramic substrate 28.

Title: Method of forming ferroelectric thin film
Inventor: HASEGAWA TADASHI
IPC: C23C14/08
Filed: 1987-06-09
Abstract: PURPOSE:To enable a ferroelectric thin film of the film quality having excellent insulating characteristic to be formed easily by giving the effect of annealing selectively to only the surface of a film under film formation without raising the substrate temperature. CONSTITUTION:In the process of forming a ferroelectric thin film by a sputtering method through causing a substrate 22 to pass over a plurality of targets 24, 25 periodically, the accumulation of film and the heat oxidation treatment are caused to proceed simultaneously by heating momentarily only the surface of a film being formed between the targets 24, 25 selectively by using an optical heating means, such as flash lamp 28. Accordingly, in the case, for example, of a substrate, on which a transparent metallic oxide film is formed in advance, the bonding strength between a constitutive metal atom under film formation and an oxygen atom can be improved without increasing the resistance of said transparent metallic oxide film. Thereby, a ferroelectric thin film of the film quality having excellent insulating characteristics can be obtained easily.
