Abstract: PURPOSE:To prevent a user from feeling cold even though the hot-water is not raised up to an unnecessarily high temperature in winter season with a rather simple constitution by furnishing a carbon dioxide generating device and a dissolving device, by which carbon dioxide gas is dissolved into water, in a shower head. CONSTITUTION:A shower head 1 has a closed type egg-plant-like shape with a cavity inside, and is attached to the downstream end of a hot-water supply pipe 13. One side face of the head should be a shower face 7 with many small- bore holes. An attachment 3 and a spiral shape thin constricted pipe 4 are mounted inside the shower head, and one end of constricted pipe 4 is connected to the attachment 3 and the other is opened. A miniature carbon dioxide cylinder 2 is mounted on the attachment 3, and a lid 5 is provided on the top of the shower head 1 to replace the carbon dioxide cylinder 2. The carbon dioxide gas spouting from the cylinder 2 is discharged from the open end of the constricted pipe 4 through the attachment 3, brought into contact with hot-water coming from the hot-water supply pipe 13, dissolved into the hot-water, and spouted from a shower face 7 together with the hot-water as carbonated shower 6.

Abstract: PURPOSE:To increase the critical current density by heating a wire material which consists of a sintered body of an oxide superconductor to fuse the outer circumference in a desired thickness, then, solidifying it, and providing a coverage of the solidified body. CONSTITUTION:A powder of an oxide superconductor or a mixture powder of it is baked temporarily, smashed, and pressed further to get a formation 3. Then the formation 3 is sintering-processed intermediately to obtain an intermediate sintered body 4. The intermediate sintered body 4 is inserted to a metallic tube body 5 to form a composite 6. Then, the composite 6 is diameter-reduction-processed to get a composite consolidated body 13, from which the outside sheath material is removed, to expose the inside consolidated body 14. After that, a thermal treatment is applied in the oxygen ambiance to the consolidated body 14 to obtain a sintered body. Since the oxide superconductor which consists of the sintered body has been sintered after consolidated sufficiently by the forging process in the diameter-reduction process, the solid phase reaction is made sufficiently, and a high critical current density is obtained. Furthermore, by the oxygen ion beam radiation at the solidification process of the outer circumference of the conductor 5, a uniform and high critical temperature is obtained.

Title: Document preparing device
Inventor: ISHII TORU
IPC: G06T3/40
Filed: 1993-03-31
Abstract: PURPOSE:To obtain the document preparing device which can freely vary the size of a bit image by converting image formation into information for displaying by a converting means for display on the basis of the correlativity between display density and print density. CONSTITUTION:A user interface part 5 actuates a printing means 2 and at the same time, a control part 4 inputs data on a bit image from a memory 3. Then the control part 4 converts the data on the bit image inputted from the memory 3 so that the size of a display image on an LCD is as large as an output image as a print result. For example, when the print density of the printing means 2 is three times as large as the display density of a display means 1, each dot of the bit image data of the memory 3 is converted into 3X3 dots. Consequently, a print which is rougher than the original performance is obtained, but the output image of the same size with the image displayed on the display means 1 is printed, so the print result that a user expects is obtained.
