Title: Manufacture of solid electrolytic capacitor
Inventor: MATSUMURA KOJI
IPC: H01G9/00
Filed: 1987-07-08
Abstract: PURPOSE:To improve impregnating rate of a semiconductor layer with respect to an anodic base body to enhance capacity in a small volume, by forming the semiconductor layer under specific low temperature range. CONSTITUTION:Employing a metal having a valve action, such as aluminum, tantalum, niobium, titanium or the alloy thereof, etc., as a base body of a valve metal used for an anode, a dielectric oxide layer is formed over the surface of the anodic base body. Next, a semiconductor layer whose base material consists of lead dioxide or both of lead dioxide and lead sulfate is formed over the dielectric oxide layer by chemical deposition under temperature between 28 deg.C and 44 deg.C. Then, a conductive layer is formed over the semiconductor layer by depositing a metal layer or a carbon layer, or by depositing the metal layer next to the carbon layer. As a result, the dissipation factor of the capacitor can be not only reduced, but the capacitance thereof can be increased.

Filed: 1984-08-15
Abstract: PURPOSE:To enable sharp reduction of production of nitrogen oxide at each burner, by a method wherein nozzle groups different in an injection direction are formed in a nozzle tip, and a mixing ratio of air to fuel injected through each group is varied. CONSTITUTION:A steam flow 12 flows through the central part of a nozzle tip 2 to each fuel injection nozzle, a fuel flow 13 is fed through a fuel groove 7, and is fed through an outer spray fuel hole 17, a middle spray hole 18, and an inner spray hole 19 to an outer injection nozzle 8, a middle injection nozzle 10, and an inner injection nozzle 11, respectively. The fuel is sprayed at injectin angles different from each other to form outer spray 14, a middle spray 15, and an inner spray 16. The air for combustion is fed from periphery of a nozzle body, and thereby the outer spray 14 is fed to a combustion air excess region to be excellently burnt to form a high temperature flame and bear a thermal load. The fuel, sprayed through the middle injection nozzle 15 and the inner injection nozzle 16, is evaporated and a part thereof is burnt. But, the fuel is brought into a state in that the air for combustion is in short supply, and thereby the fuel forms a reduction flame serving to reduce NOx. This enables reduction of nitrogen oxide at each combustion device, resulting in the possibility to sharply reduce production of nitrogen oxide.

Filed: 1997-05-21
Abstract: PROBLEM TO BE SOLVED: To provide a splashguard device which can be applied to a position where water splash occurs in a company or the like by fitting it at the inside of a splashgruad on a vehicle or at the rear part of the vehicle. SOLUTION: An attenuation device 1 is fitted on the channel side of a guide channel device 2, and a collecting and discharging device 3 is fitted on both sides of it respectively at a position where water splash tends to occur. Namely, when a vehicle runs on a road on a rainy day or on a wet road, water splashes. The water splash first hits the attenuation device 1 to weaken its force. The water splash which has passed through the attenuation device is flowed into the collecting and discharging device 3 on the both ends along the channel without splashing by the guide channel device 2. As a result, water splash is discharged only from several positions, thus it is possible to prevent water from splashing.
