Title: Injection catheter, intravascular site treating method, and production of catheter
Inventor: MAIKERU KUROTSUKAA
IPC: A61M29/02
Filed: 1994-06-24
Abstract: PURPOSE: To provide a low-profile infusion catheter having an improved flexibility characteristic. CONSTITUTION: Four different flexible zones 101 to 104 are formed, with an approximately constant external profile maintained as a whole, and the most proximal zone 101 is a part extended from an adapter to an interface 41. The zone 102 has the first material extension part at a position adjacent to a lumen, and this lumen is more flexible than the first material of the zone 101. As a result, the combination of the part of the flexible zone 102 and the tubular part becomes an assembly catheter body having slightly higher flexibility than the zone or segment 101. The flexible zone 103 has higher flexibility than the flexible zone 102, while the flexible zone 104 has higher flexibility than the flexible zone 103. As a whole, the flexibility gradually becomes higher over an area from the proximal zone to the distal zone.

Title: Filter medium for water purifier
Inventor: ISHIZAKI HIDEKAMA
IPC: C02F1/50
Filed: 1983-08-05
Abstract: PURPOSE:To obtain a filter medium for water purifier inhibiting proliferation of bacteria even if the water stagnates during purification, from a mixture consisting of 20-30wt% active carbon supporting silver, 10-15wt% active carbon supporting copper, and 55-70wt% pure active carbon. CONSTITUTION:20-30wt% active carbon supporting 0.35-1.0wt% silver on the surface, 10-15wt% active carbon supporting 0.5-3.0wt% copper on the surface, and 55-70wt% pure active carbon are mixed to obtain a filter medium for a water purifier. By regulating the amt. of silver supported by the active carbon to 0.35-1.0wt%, the concn. of silver ion in the stagnating water is regulated to 10-50ppb. When the above described filter medium is used, elution of silver is retarded by the presence of copper ion. Proliferation of bacteria is prevented even if stagnation of water for a long time is caused since proliferation of bacteria is inhibited by the sterilizing effect of coexisting copper ion.

Abstract: PURPOSE:To obtain a clear image without generating the uneveness of density and fogging even when continuous image forming is performed by providing a separating device which charges an image supporting body with at least two different kinds of alternating current charges. CONSTITUTION:When an image carrier is passing through, a first alternating current voltage is impressed, and when the image carrier is not passing through, a second alternating current voltage, which is higher than the first alternating current voltage, is impressed and the separating device 24, which charges the image supporting body 10 with the alternating current charges of different quantity, is provided.

Thus, the belt-shaped fogging and the uneveness of the density are dissolved and the excellent image is obtained for a long period.

Title: Liquid fuel combustion device
Inventor: KONAKAWA KATSUZOU
IPC: F23D3/02
Filed: 1982-08-20
Abstract: PURPOSE:To enlarge the variable range of combustion quantity by making variable the combustion gas passage area by first variable means to vary the flowpath resistance, making variable the area of an opening provided in an inner flame cylinder by second variable means, and varying the quantity of air flowing in through the opening and the heat draft by cooling. CONSTITUTION:The maximum combustion quantity can be determined depending upon the areas of main and auxiliary combustion gas passages 20 and 21 and closure of an opening 24. However, with less than a predetermined combustion quantity, soots and unburnt gases are generated due to air deficiency. Therefore, by supplying a large amount of air through the opening 24 to the combustion flame completion zone, it becomes possible to complete the combustion. Further, since air flowing into the device through the opening 24 is mixed with the combustion gas, it is possible to widely set the required precision of a resistance plate 22 and the main combustion gas passage not only by the reduction of the draft due to the lowering of the temperature but by the volmetric increase in the entire waste gas. Therefore, the variable range of the combustion quantity can be enlarged.
