Title: Water quality purifying device
Inventor: SETO MASAYUKI
IPC: C02F1/28
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To exhibit large water purifying performance with a synergistic work of porous concrete with a phosphorus adsorbent and to enable to produce the device at a low cost by forming both a main water purifying tank using the porous concrete as water purifying substance inside a box-shaped main body and an auxiliary water purifying tank using the phosphorus adsorbent as water purifying substance. SOLUTION: The water introduced from a pool with an inlet pump 20 into the inside of a water purifying device 10 passes through a large number of holes in the porous concrete 14 of the main water purifying tank 12, and organic material and nitrogen compounds are chiefly purified with a work of the microorganisms adhered to the surface of a large number of the holes of the porous concrete 14. Phosphorus is released into water from the interior of the living body such as plankton in water and the water passed through the main water purifying tank 12 flows in the auxiliary water purifying tank 13 from a water inflow port 24. In the auxiliary water purifying tank 13, the phosphorus is adsorbed with the phosphorus adsorbent 15 and the water is almost perfectly purified and this purified water is returned to the pool from an outflow port 19 with an outflow pump 22.

Title: Etching method
Inventor: ABE KAZUYUKI
IPC: H01L21/308
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To improve the etching speed, in the etching method which wet-etches the diffusion preventive layer consisting of titanium - tungsten alloy out of a base layer by etchant including a hydrogen peroxide. SOLUTION: Copper which is lower in free energy of production of an oxide than titanium - tungsten alloy is mixed in advance into etchant 20. In this case, the mixed copper is a copper oxide, being oxidized in etchant 20 by a hydrogen peroxide. Then, when a diffusion preventive layer 15 is soaked in the etchant in this condition, the diffusion preventive layer 15 is removed by etching by the copper oxide oxidizing the titanium - tungsten alloy forming the diffusion preventive layer 15. The etching speed in this case is higher than the etching speed in removal by etching of the diffusion layer 15 made by the oxidation of the titanium - tungsten alloy by the hydrogen peroxide, thus the etching speed can be improved.

Title: Read control circuit for memory unit
Inventor: HIURA TADASHI
IPC: G11C8/00
Filed: 1978-08-30
Abstract: PURPOSE:To increase the read speed of a memory by attaining selective access to a memory where odd and even-address data have been stored by the least significant bit (LSB) of an address signal. CONSTITUTION:By read clock S1 and count-up signal S2, LSB of an address signal from register 3 is updated in each period of clock S1 and remaining bits are in every other bit; and even and odd memories where even and odd-address data have been stored are selected by turns by LSB and that after passing through inverter 6. On the other hand, bits other than LSB from register 3 are delayed by one period of clock of clock S1 by the AND output of AND gate 5 receiving clocks S1 and S2 and then transferred to register 4. Therefore, memories 1 and 2 can be read at a high speed by addressing to memories 1 and 2 by registers 3 and 4 which output addresses in a shorter time than the access time of memories 1 and 2.

Title: Lead damper with axial shift adjusting mechanism
Inventor: YAMADA SHUNICHI
IPC: E02D27/34
Filed: 1995-04-05
Abstract: PURPOSE: To prevent the vertical stress fluctuation of a lead body and secure the pure shearing deformation of the lead body by fixing a plastic deformation section made of the lead body on one side of a structure, arranging an axial guide mechanism section allowing a vertical shift on the other side, and arranging link mechanisms on both sides of the plastic deformation section. CONSTITUTION: When earthquake force is applied, upper and lower structures G, B are relatively displaced in the horizontal direction. A link mechanism section 2A mainly follows the displacement of the upper structure G. The deformation of the lead body 4 of a plastic deformation section 1 is restricted by the displacement of the link mechanism section 2A. The vertical shift of a vertical guide mechanism section 2B is restricted by the deformation of a link mechanism section 2B. The fluctuation of the lead body 4 in the height direction is absorbed by the shift of a piston body 18 caused by the fluctuation of the lower link of the link mechanism section 2A. No excessive tensile resistance is applied to the lead body 4. The axial deformation stress applied to the lead body 4 is mitigated, and the pure shearing plastic deformation can be obtained.

Title: Fixing structure of roofing material
Inventor: JIYOUDA KATSUAKI
IPC: E04D1/34
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To easily connect mutual roofing materials without level differences, by fixing roof tiles to each other through forked nails in the state the forked nails have stucked to spacers. SOLUTION: This roofing structure is constituted of roof tile bodies 1 and spacers 3 arranged in the hollow space at the rear face side of only the butted part of mutual roof tile bodies 1. A forked nail 2 is put astride on the butted part so as to stick the spacer 3 and fix the mutual roof tile bodies 1. By the presence of this spacer 3, the space at the rear face side of the roof tile bodies is filled. And hence, even when the forked nail is driven, the roof tile body is not easily broken. And further, since the roof tiles are directly positioned to butt each other and the forked nail is only driven, the installation of mutual roof tiles in the vertically lateral direction against the direction of the eaves gutter, is easily completed and the workability is improved.

Title: Image scanner
Inventor: KAWAI YASUHIRO
IPC: G03G15/22
Filed: 1981-07-06
Abstract: PURPOSE:To reduce time loss during replacement of a sheet to be scanned, by continuously rotating a sub-scanning drum throughout at a constant speed. CONSTITUTION:When a sheet 1 to be scanned is fed while sandwiched between a sub-scanning drum 11 and nip rolls 12 and 13, this sheet 1 is separated completely from a couple 8 of sheet supplying rolls and a couple 2 of ejecting rolls, so the driving force of the couple 8 never interfers with the sheet 1 and the couple 20 does not comes into contact with the sheet 1 during a main scan to vary the feeding speed of the sheet. Further, the sub-scanning drum 11 rotates continuously throughout at a certain speed, so the need to readjust the position of the drum during sheet loading is eliminated. Further, the sheet 1 is ejected by falling from the drum 11 by its own weight, so even if sheets 1 are fed being stacked from the sheet supplying roll 8 by mistake, no jams occurs.

Title: Corrosion resisting sliding contact member and its production
Inventor: MATSUKAWA KIMIAKI
IPC: C23C28/00
Filed: 1993-05-06
Abstract: PURPOSE:To obtain a sliding contact member capable of performance over a long period without maintenance and keeping corrosion resistance by forming a film of two-layer structure, consisting of corrosion resisting film and wear resistant film, on the surface of a base material. CONSTITUTION:For example, a film 2 of precipitation hardening alloy, such as Ni-P, Ni-B, and Ni-W, of 50mu film thickness in amorphous state is formed on a base material 1 of sliding contact part made of iron and steel material SUS440C. Subsequently, photoirradiation is applied to the film 2 and, in the state where amorphous Ni is allowed to remain, these Ni compounds 4 are precipitated in the film 2. The film 2 is a corrosion resisting film and can be formed by means of amorphous electroless plating or amorphous electroplating. Although a sliding contact member in a link mechanism, etc., is allowed to slide when the performance of the link mechanism, etc., is done, the hardness of the film 2 as a whole is improved because the Ni compounds 4 are precipitated. Accordingly, wear resistance of the film 2 as a whole is improved and the occurrence of damage, due to sliding, in the part plated with the amorphous alloy can practically be prevented, and its corrosion resistance can be maintained over a long period.
