Title: Power supply
Inventor: YAMAMOTO HIROTAKA
IPC: C04B35/46
Filed: 1989-05-25
Abstract: PURPOSE:To increase output or reduce size of various kinds of power supply by a method wherein a ceramic capacitor using strontium titanate ceramic is used as a member of a circuit. CONSTITUTION:Ceramic 1 of strontium titanate, lanthanum titanate, and barium titanium is used as a ceramic capacitor. This is employed in a power supply device with ceramic 1 used where relative dielectric constant is 510 to 820, dielectric loss is 0.02% or less, voltage dependence of 1kV/mm electrostatic capacity is 0.5% or less per electric field having thickness of dielectric material, and reduction ratio of electrostatic capacity at 85 deg.C with respect to the electrostatic capacity at 20 deg.C is 37% or less. Even if the dielectric constant is relatively large, the rise in temperature during use can be reduced since the high frequency dielectric loss is small; and deterioration in electrostatic capacity during electricity charging can be reduced. This enables increase in output and reduction in size of a power supply.

Title: Frequency converter
Inventor: SAKAGUCHI YASUNORI
IPC: H04N9/87
Filed: 1985-06-13
Abstract: PURPOSE:To obtain a device of a reduced number of pins when integrating by amplifying a chrominance signal having a carrier wave of the first frequency by an automatic gain control amplifier, mixing the frequency of the amplified chrominance signal with a comparison signal of the second frequency by a multiplier to output to a band pass filter. CONSTITUTION:A chrominance signal having a carrier wave of 2.56MHz inputted to an input terminal 1 is converted to a chrominance signal having the carrier wave of 2.56MHz of a fixed amplitude level by an automatic gain control amplifier 7 in accordance with the amplitude level of an output signal from a switch 9. This chrominace signal is frequency mixed with a comparison signal of the frequency centering 6.14MHz from a voltage control oscillator 3 by a multiplier 2 to output as the chrominance signal in which the frequency is converted to 6.14MHz+ or -2.56MHz to an input terminal 4 for BPF. Thereby, since the output signal from a band pass filter 5 becomes to the chrominance signal having the carrier waves of 3.58MHz restricted to the fixed amplitude level, it can be used as a signal for a signal processing in a later step as it is. Therefore, when integrating, the terminal of the signal processing in the later step is not required.

IPC: C10G55/02
Filed: 1979-10-12
Abstract: PURPOSE: To recover efficiently light oil contg. less metal components, by a method wherein a gaseous solvent which is nearly in a critical state is contacted with heavy oil which has been partially converted to light oil by thermal cracking.  
     CONSTITUTION: Heavy oil from a line 5 is introduced into a packed column 1, and heated at a temp. (about 380W450°C) at which the heavy oil is not completely decomposed, in order to convert, part of the heavy oil to light oil. A gaseous solvent which has been supplied through a line 6 and compressed nearly to critical pressure in a compressor 3, is introduced into the packed column 1 and contacted with the heavy oil to extract the light oil component in the heavy oil into a vapor phase until equilibrium is attained. Then the pressure of the light oil component extracted into the vapor phase is reduced by a reducing valve 4. The light oil component is cooled and condensed by a condenser 2, and recovered through a line 9. While part of noncondensed gas is discharged through a line 7, the remaining part of the gas is recycled to reuse it. As the solvent, a solvent whose critical temperature is close to the heavy oil-processing temperature, is selected from the group consisting of propane, butane and toluene.
