Abstract: PURPOSE:To burn fuel completely in the furnace of a boiler, by properly determining the ratio of fuel and air, by subtly controlling the number of revolution of a blast induction motor by changing the frequency of an inverter, in addition to control the air rate by controlling the opening of a damper. CONSTITUTION:A flow rate controller 1 controls a fuel 2 and feeds the fuel 2 into a burner 3. A blast induction motor 4 controls the rate of air 5 by its number of revolution. A frequency setter 6 outputs a signal to determine the frequency of an inverter 7, and the inverter 7 determines the number of revolu tion of a blast induction motor 4. The potential of respectively different standard is impressed on each +terminal of the comparator 20-24 of a frequency setter 6, and -terminal selects the comparator 20-24 by the potential output in accor dance with the opening of a damper 13 which is controlled by the motion of a link 12. The signal subtly controlled in variable resistors 43-47 on the basis of the selected output potential is fed into the inverter 7. The output from the inverter 7 controls the number of revolution of a blast induction motor 4, and the air rate at each point of angle of a damper 13 is subtly controlled by the motion of a link 12.

Title: Synchronous transmission system
Inventor: NAKAJIMA AKIHIRO
IPC: H04L25/49
Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To provide a code type, with which the preparation of code is made simple and the extraction of synchronizing signal is facilitated even when data '1' or '0' are continued, by making the data '1' or '0' into a voltage waveform which is turned from an intermediate level voltage to a high or low level voltage during 1 bit of data cycle, returned to the intermediate voltage level after continuation for fixed time and continued for fixed time. SOLUTION: When sending data '1', these data are made into voltage waveform which is increased from an intermediate value to a high level in the biginning of 1 bit of data cycle, keeps the high level for fixed time, drops to the intermediate value later and keeps the intermediate value for fixed time. When sending data '0', these data are made into voltage waveform which is decreased from the intermediate value to a low level in the biginning of 1 bit of data cycle, keeps the low level for fixed time, rises to the intermediate value later and keeps the intermediate value for fixed time. Thus, even when '1' or '0' continuously exists in data to be transmitted, the synchronizing signal can be easily extracted from the voltage change of respective bits.

Title: Formation of superconducting film of oxide
Inventor: KOJIMA KAZUYOSHI
IPC: C23C14/08
Filed: 1988-05-12
Abstract: PURPOSE:To obtain desired superconducting films in good reproducibility, by forming metallic electrodes on the surface and the back of a substrate, connecting an oscillator to the electrodes, metallizing thin films containing each constituent metal element of oxide superconductor on the surface and the back, respectively while monitoring natural vibration of the substrate and heat-treating the prepared laminated films. CONSTITUTION:Metallic electrodes 3 are formed on the surface and the back of a substrate 1 and an oscillator is connected to the metallic electrodes 3. Thin films containing each constituent metal element (e.g., Y, Ba and Cu) of oxide superconductor are metallized, respectively on the substrate 1 while monitoring natural vibration of the substrate 1 and laminated films having desired stoichiometric ratio is formed. Then the laminated films are heat-treated to give superconducting films of oxide. Consequently, since the number of natural vibrations of the substrate 1 is proportional to films metallized and laminated to the substrate 1, weight of each thin film of each constituent metal element metallized to the substrate 1 is known by monitoring the number of natural vibrations. Therefore laminated films of stoichiometric ratio can be accurately formed in good reproducibility.

Filed: 1997-05-08
Abstract: PROBLEM TO BE SOLVED: To prevent an audio signal from being illegally copied. SOLUTION: A digital audio signal in a prescribed block unit supplied via a segmentation part 12 is fast-Fourier-transformed by an FFT(fast Fourier transform) part 13, and a resultingly obtained frequency spectrum is supplied to a spectrum operating part 14.

Title: Movable-core type reactor
Inventor: MISAWA KAZUHISA
IPC: H01F37/00
Filed: 1979-09-12
Abstract: PURPOSE:To increase inductance in proportion to an increasing current by a method wherein a gap provided in a reactor core in accordance with energizing is closed by the movable core. CONSTITUTION:A coil 1 is inserted surrounding a fixed core 6 and the outside of the coil 1 is enclosed by a yoke 5, which is formed in such way that both end surfaces 7 are opposing each other maintaining a distance l. A core 8 is inserted in the opening provided between the two end surfaces 7 and the core 8 is hang up in such way that it is maintaining a gap g between the core 6 with a nonenergized coil 1. When short-circuited current is conducted to the coil 1, the sucking force at the gap g section increases, the core is pulled downward reducing the length of the gap g and the inductance of the reactor is increased. Therefore, a voltage drop due to reactor in normal operation is small if a ratio for the gap g length of the core 8 is properly selected and a short-circuit current caused by reactor can be suppressed at a safe value in case of a short-circuit load.
