Title: Bridge-type dc boost converter for drive of capacitive load
Inventor: MIHARA MASAAKI
IPC: H05B44/00
Filed: 1999-03-23
Abstract: PROBLEM TO BE SOLVED: To drastically reduce the loss of energy by a method, wherein a Zener diode is connected in series with switching circuits connected to both sides of a capacitive load. SOLUTION: A connection point C of the cathode of a first diode 18 to an electroluminescent(EL) panel 19 is grounded via a first Zener diode 21 and a third switching transistor 22 as constant-voltage elements, which are connected in series. In addition, a connection point D of the cathode of a second diode 20 to the EL panel 19 is grounded, via a second Zener diode 23 and a fourth switching transistor 24. The cathode of the first Zener diode 21 and the cathode of the second Zener diode 23 are connected in the direction of the EL panel 19, and their threshold voltages are made higher than the supply voltage of a DC power supply. As a result, the loss of energy can be reduced, and the EL panel 19 can generate bright light over a long period.

IPC: B01D51/00
Filed: 1983-05-06
Abstract: PURPOSE:To provide the treatment with high dust collecting efficiency which is applicable to a large-scale, high-temp. gas contg. dust by introducing the gas contg. dust into a filter tube, which is vertically installed and consists of an air-permeable porous solid body, from the upper part while swirling in the circumferential direction of the filter tube, and passing the gas through the wall of the filter tube. CONSTITUTION:A cylindrical filter tube 1 consisting of a porous body such as a ceramic sintered body is installed vertically, and a cylindrical body 31 of a revolving impeller 3 is mounted on the upper end surface of the tube 1. A gas contg. dust G is introduced into the revolving impeller 3 from an introducing pipe through a guide cylinder 81, swirling downward along the inner surface of the filter tube 1, and collected in a dust sink 6. The gas, flowing inside of the filter tube 1, passes gradually through the wall of the filter tube, and is discharged to the outside as a clean gas G'.

Title: Instrument for measuring adsorption quantity
Inventor: ISHIDA SHOHEI
IPC: G01N15/08
Filed: 1990-03-26
Abstract: PURPOSE:To shorten the time for measurement by providing a resistor the fluid resistance value of which varies with a difference between the gas supply pressure from a gas supply source and the internal pressure of a manihold at the intermediate point of a gas flow passage from the gas supply source to the manihold. CONSTITUTION:The resistor 18 is provided in a gas introducing path communicating with the inside of the manihold 30 from the gas introducing port 30a via a valve 7. Annular bellows 18c is disposed in the resistor 18 and a porous body 18d is packed in the central space part of the bellows 18c. The resistance value of the flow rate by the porous body 18d is high when the pressure difference between the gas introducing port 30 a and the manihold 30 is large. The resistance value of the flow rate is low when the pressure difference is small. The smaller change in the gas flow rate to the manihold 30 is, therefore, necessitated even if the pressure difference between the gas introducing port 30a and the manihold 30 varies. Consequently, the control of the gas introducing pressure to the manihold 30 by the opening and closing operations of the valve 7 is facilitated.

Title: Spectrum analyzer and graphic equalizer
Inventor: CHIBA MASATOSHI
IPC: H04B14/00
Filed: 1996-03-06
Abstract: PROBLEM TO BE SOLVED: To simplify a constitution by taking out a scale factor with amplitude information applied for each predetermined sub-band from an MPEG audio signal for storage and displaying the amplitude information for each sub band. SOLUTION: An MPEG audio signal generator SG outputs an MPEG signal, and a scale factor take-out part 10 takes out a scale factor from the MPEG audio signal. A multiplexer 20 distributes the scale factor into 34 for each sub-band. The distributed scale factor is stored in each of registers R1 to R34, and amplitude information corresponding to the stored scale factor is displayed by display devices LED 1 to LED 34. Thus even if frequency resolution is raised, registers only may be added, and since the registers are not so large, a circuit size may not be large with its structure simple.

Abstract: PURPOSE:To prevent the production of a discontinuous part of the second layer at the stepped part by forming a layer connected to the side surface of the first layer on a substrate and inclined from the side surface to the surface of the substrate to compensate for the stepped art and then laminating the second layer. CONSTITUTION:An SiO2 23, and a conductive polysilicon 24 are laminated on an Si substrate 21, and a side surface 26 is vertical to the surface 22 of the substrate. A CVD SiO2 28 is then covered in a thickness selected in a range of 50- 150% of the height of the surface 27 of the layer 25 on the surface 22 of the substrate. Subsequently, when it is etched by reactive sputtering with CF4+H2, the surace 29 of a layer 30 is extended continuously from the upper surface of the layer 25, is ended to the main surface 22 of the substrate, thereby compensating the stepped part. Then, thermally oxidized films 31, 32 are connected to the layer 30, and a conductive layer 33 such as Mo is continuously extended. According to this structure, even if the side surface 26 of the layer 25 is vertical to the substrate, a discontinuous part is not formed on the second layer 33 on the upper surface due to the presence of the stepped part compensating layer 30.

IPC: F23C1/10
Filed: 1983-05-06
Abstract: PURPOSE:To reduce the heat loss caused by unburnt matters and at the same time decrease NOx and reduce troubles due to ashes by a method wherein the excess air ratios of the respective burners for exlcusive use are changed, when the mixed firing of solid fuel in a boiler for burning exclusively heavy oil, for burning exclusively gas, or for mixedly burning heavy oil and gas is intended. CONSTITUTION:A burner for the exclusive use of heavy oil or gas and a burner for solid fuel use are respectively and independently set so adjacent as to be interfered each other. The excess air ratio of the respective burners is controlled to have the excess air of 1.5 and more for the fuel, which is easy to burn, such as heavy oil, gas or the like and to have the excess air of 0.7 and less for the solid fuel, which is difficult to burn and yet to have enough air amount with respect to total fuel so as to ensure the residual O2 in the exhaust gas after combustion not less than 0.5. As a result, the whole furnace of a boiler is acted effectively as a combustion space under uniform temperature, resulting in not only establishing the reduction of the heat loss caused by unburnt matters and at the same time the decreasing of NOx but also remarkably reducing the troubles due to the molten ashes of the solid fuel by preventing a locally high temperature region from developing.
