Title: Circulation type electric vacuum cleaner
Inventor: TANAKA MASATOSHI
IPC: A47L9/26
Filed: 2000-01-31
Abstract: PROBLEM TO BE SOLVED: To provide a circulation type electric vacuum cleaner which prevents its body from excess heat rising and can improve dust inhaling capacity according to need. SOLUTION: This is a perfect circulation type electric vacuum cleaner first of all. An air release valve 71 is fixed in a returning air passage in which discharged air emitted from an electric air blower 22 built-in a cleaner body and sent back to an inhaling body passes. A controlling method which controls the air release valve 71 open/shut and the electric air blower power input. The controlling method 96 increases the electric air blower 22 power input at the same time as a vent 71 is opened, and decreases the electric air blower 22 power input at the same time as a vent 71 is closed.  This control improves the electric air blower 22 inhaling capacity as well as opens the air release valve 71 and enables it to collect dust around the inhaling body as conventional non-circulating electric vacuum cleaner does and then it emits the discharged air to the atmosphere and promotes the electric air blow 22 radiation to control heat-up of rising the cleaner body.

Title: Tampon having fiber lumps
Inventor: SUGA FUMIYOSHI
IPC: A61F13/20
Filed: 2000-02-02
Abstract: PROBLEM TO BE SOLVED: To prevent a tampon from producing a clearance between the tampon and the vagina. SOLUTION: An absorber 2 is formed by a tight hydrogen bond of a plurality of compressed fiber lumps 8. The absorber 2 is covered with a water permeable sheet 3. In the tampon, as a hydrogen bond binding the fiber lump 8 breaks when the tampon absorbs menses, individual fiber lumps 8 freed as a result of breakage of the hydrogen bond restore their original shapes so as to absorb a liquid and expand. Therefore, the absorber 2 expands and quickly blocks a clearance with the vagina and prevents a clearance from occurring.

IPC: C02F3/00
Filed: 2000-02-16
Abstract: PROBLEM TO BE SOLVED: To efficiently perform electrolytic treatment of water. SOLUTION: A water purification device is provided with a purification vessel 3 within which six vessels are placed so that they are communicated meandering with each other by using partition walls 15 and intermediate partition sections 16. Of the six vessels, the second and third vessels from the left side in the figure are filtration vessels 3b and 3c, respectively. In the lower part of each of the filtration vessels 3b and 3c, a large number of electrode plates 20 are placed at specified space intervals in such a state that each of the plates 20 crosses the partition walls 15 and the plate surface of one of the intermediate partition section 16, and these electrode plates 20 are connected to a DC power source so that they are alternately positive electrodes and negative electrodes. When water flows meandering through the filtration vessels 3b and 3c, there is a possibility of causing variation in flow velocity in the width direction of the water flow passage. In such a case, although some variation in flow velocity may be partly caused in each of the electrode plates 20, no variation in flow velocity is caused in each of the electrode plates. As a result, each of the electrode plates 20 uniformly exhibits its electrolytic treatment capacity to efficiently perform electric treatment as a whole.

Filed: 2000-03-07
Abstract: PROBLEM TO BE SOLVED: To provide an image processing apparatus and an image processing method which shorten a period needed to read an image and perform printing in a short time. SOLUTION: In a step S2, pre-scanning is performed, and the position and size of a document on an original platen are specified due to contour extraction, and in a step S3, real scanning is performed. Thus, a read distance can be made short in accordance with the length of an original in a vertical scanning direction on the original platen about the original whose size is relatively small by reading the image of the original in accordance with the specified position and size data. Then, a period needed to read the image can be shortened, and consequently, printing can be performed in a short time.  Furthermore, because the original position and the original size on the original platen are specified by extracting the contours of the pre-scanned image, a special part or device does not have to be incorporated, the period needed to read the image can easily and reliably be shortened with a simple configuration and the printing can be performed in a short time.
