IPC: F24D11/00
Filed: 1990-06-08
Abstract: PURPOSE:To enable high-temperature heat storage and take out hot-water or vapor efficiently through heat medium such as heat resistant oil or the like by filling a vessel having a heat resistant property with heat storage bricks. CONSTITUTION:A heat storage element 1 is constituted of a hollow metallic pipe (vessel) 3 filled with heat resistant bricks 2 and lids 4, plugging both end openings of the metallic pipe 3 to intercept the heat resistant bricks 2 in the metallic pipe 3 from environment. When the heat storage element 1 is heated by a sheath heater or the like from the outside of the metallic pipe 3, the temperature of the heat storage bricks 2, filled into the metallic pipe 3, is increased together with the temperature rise of the metallic pipe 3 whereby high- temperature heat is stored. Heat storage energy, stored in the heat storage bricks 2, is taken out by the heat resistant oil (heat medium) flowing though the outside of the metallic pipe 3 as hot-water or vapor and is utilized for heating and other usage.

IPC: H01L29/72
Filed: 1987-06-17
Abstract: PURPOSE:To improve performance by composing a transistor onto a substrate, which can be acquired by alternately conducting the formation of, a high- concentration impurity region as a buried layer and epitaxial growth plural times and has partially different epitaxial thickness. CONSTITUTION:Buried diffusion layers 302 are formed onto a substrate 301, an epitaxial layer 304 or another buried layer 303 is shaped onto the layers 302, and another epitaxial layer. 305 is positioned to the upper section of the layer 304 or 303. A high-speed bipolar transistor 306 and a high breakdown- strength bipolar transistor 307 are organized into the epitaxial layer region 305. Consequently, since the epitaxial thickness of a section where the high-speed transistor 306 is positioned is thinned, collector resistance can be lowered, thus realizing higher-speed properties. On the other hand, the epitaxial thickness of the high breakdown-strength transistor section 307 is thickened, thus obtaining desired breakdown strength.

Title: Image forming device
Inventor: KOITABASHI NORIFUMI
IPC: G03G15/047
Filed: 1987-06-17
Abstract: PURPOSE:To prevent a developer from sticking to a transfer device at the time of transfer by previously detecting the width of a transfer material and making the width of a latent image formed on an image carrier as same as that of the transfer material or less. CONSTITUTION:The width of the transfer material P is previously detected and the width of the latent image formed on the image carrier 1 is made as same as the width of the transfer material P or less. For example, when specification members 18a and 18b are allowed to abut on the edge parts of the transfer material P placed on a feeding tray 11 by moving them from a state where they open to both sides in the width direction of the feeding tray 11 to inner part, operational arms 27a and 27b move in a direction where they approach by interlocking the above-mentioned members 18a and 18b and the free ends of both light shielding members 26a and 26b move to inner part, so that the scanning width Wb on the surface of a photosensitive body by a laser unit 25 is narrowed to a width Wa which is nearly as same as the width of the transfer material P or a narrower width than that. Thus, the toner can be prevented from sticking to a transfer roll 4 at the time of transfer.

Title: Dry-cleaning method for clothes stuck with water soluble soil
Inventor: MISHINA KENJIRO
IPC: D06F43/00
Filed: 1998-06-01
Abstract: PROBLEM TO BE SOLVED: To remove water-soluble and oil soluble soil stuck on clothes made of wool or wool blending fiber with keeping crinkle to a minimum by transferring normal drying process, when it detects that the outlet temperature reaches the certain temperature at which clothes get no damage and making it possible to shorten a drying time with keeping crinkle to a minimum. SOLUTION: The drying process is performed using the swing rotation (S12) the same as the washing process. And the temperature rises gradually at the outlet, and when it is detected that the temperature reaches the certain setting temperature at which clothes get no damage (S13), it returns the degree of vacuum to normal pressure and works the drying process with normal rotation (S14). As the experiment research result, the temperature that gives no damage to clothes is about 50 degrees centigrade. Drying with the swing rotation to 50 degrees centigrade of the outlet temperature, it keeps the crinkle for clothes to a minimum. After reaching that temperature, as it transfers normal rotation, it is possible to shorten the time to drying finish (S15) with avoiding the crinkle.
