Title: Method-control-method and device for low b.t.u. high-moisture fuel combustion
Inventor: UORUTAA TOOMASU MAREN
IPC: F23G7/02
Filed: 1989-01-13
Abstract: PURPOSE: To improve the combustion performance of combustion equipment using waste wood, etc., as fuel by enriching process air used in the combustion process, so that the drying speed of the fuel may be increased by increasing the reacting rate of the fuel and raising the combustion temperature of the fuel. CONSTITUTION: When fuel composed of lumbering waste is sucked into a space about 15-20 feet above a hearth, the fuel drops onto a perforated fire grate on which a charcoal layer is formed. Then primary air containing added oxygen is supplied through the fire grate and secondary air containing added oxygen is supplied to a space about four feet above the hearth. When the primary and secondary air enriched in oxygen are supplied in the above-mentioned way, the combustion speed of the fuel increases and thermal flux (temperature) in the combustion zone rises. Consequently, the heating and drying speeds, the combustible volatile matters by thermal decomposition, the amount of charcoal, and the reaction rate by the production of porous charcoal can be increased and the low B.T.U./high moisture content fuel can be burned efficiently. Therefore, the used amount of underground fuel can be reduced.

Title: Method for assembling metallic product
Inventor: UEDA KENJI
IPC: C23F13/00
Filed: 1989-01-18
Abstract: PURPOSE:To prevent the galvanic corrosion of a product at the contact part between unlike metals even when a sacrificial anode is hardly welded to the product due to its quality and structure by using a clamp in which the metal of a sacrificial anode is embedded to assemble the metallic product main body. CONSTITUTION:When the Al product main body 4 is assembled by a stainless steel bolt 1 nobler than the main body, the main body 4 is assembled by the bolt 1 in which a Zn sacrificial anode 2 baser than the main body 4 is previously embedded. As a result, the Zn 2 in the anode 2 embedded in the bolt 1 is dissolved into water, and the corrosion of the main body 4 in contact with the bolt 1 is prevented. At this time, the Zn 2 functions as an anode and the main body 4 (Al) and bolt 1 (stainless steel) as a cathode. The corrosion protection can be maintained until the Zn 2 is consumed.

Title: Picture noise reducing device
Inventor: HANADA NAOKI
IPC: H04N5/93
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To fetch a picture in which noise included in a picture signal is reduced by giving inter-frame processing through the use of a circulating noise reducing circuit at the time of detecting that an inputted picture is a still picture. SOLUTION: At this device 1, a still picture detecting circuit 2 judges that the inputted picture is a still picture based on the motion detecting result of the picture and the detecting result of a color frame, a color belt, etc., showing the still picture. A still picture fetching control circuit 3 makes the circulating noise reducing circuit 4 into operating state based on a still picture detecting output 2a. A product obtained by multiplying the inputted picture by (1-K) by a multiplier 7 and a product obtained by multiplaying the output of a picture memory 9 by K by a multiplier 10 are added by an adder 8 to house the adding result in the memory 9. By repeating the processing through plural frames, noise included in the inputted picture is reduced to obtain a still picture with the reduced noise in the memory 9.

Title: Priority circuit type flow dividing valve
Inventor: TAKESHIKA SHIRO
IPC: F15B13/06
Filed: 1989-01-17
Abstract: PURPOSE:To speed up the shifting of a spool into a balanced position by controlling the inflow/outflow of oil by a protrusion at the time of a spool being shifted into an excess oil feed starting position so as to prevent the vibration of the spool and separating the protrusion from a damper passage at a normal working time so as to free the inflow/outflow of the oil. CONSTITUTION:When the feed oil quantity from a hydraulic pump is increased, the pressure in a damper chamber 10 rises, so that a spool 6 is pushed toward the left and a part of the feed oil quantity is delivered out to the excess oil delivery port 5 side. At this time, as the flow going in and out the damper chamber 10 is restricted by the minute clearance (a) between a protrusion 17 and an insertion hole 18, the vibration of the spool 6 is suppressed. In addition, in case a hydraulic actuator is suddenly changed in its operation, the protrusion 17 is placed in a position slipped out of the insertion hole 18, the oil flow into/ out of the damper chamber 10 from a damper passage 16 is freed, and thereby the spool 6 can swiftly move into the position where it can be balanced with the spring pressure of a presser spring 7, so that the fluctuation of the oil quantity against a priority delivery port 4 can be dissolved in a short time, thus enabling the smooth operation of the actuator.

Abstract: PURPOSE: To reduce damages to the surface of a wafer to an irreducible minimum by a method, wherein a clamp ring is provided which includes a ring- shaped sheet possessed of a protrudent wafer-engaging face that is engaged with the periphery of the wafer and pressing. CONSTITUTION: When a clamp ring 100 is made to descend to receive a wafer 10 with its sheet, the wafer 10 is engaged by a ball 114. A pocket 112 is formed like a cylindrical hole slightly larger in diameter than the ball 114, so that the ball is movable slightly in the pocket 112. Therefore, when the ball 114 comes into contact with the wafer 10, it stops moving downwards and moves relatively upwards, until the ball 13 and the wafer 10 are pressed by an upper cap 108 of the clamp ring 100. The ball 114 moves downwards with a downward movement of the clamp ring 100, and the wafer 10 is bent along the dome 18 of a pedestal. Then, the ball 114 on the wafer 10 rolls on it and is restrained from being dragged.

Title: Area recognition system for recorder
Inventor: FUJITA ARINORI
IPC: H04N1/38
Filed: 1991-01-28
Abstract: PURPOSE:To shorten the processing time and to decrease the cost by discriminating the respective areas in making the forward scan of the prescan, the backward scan of the prescan, and copy scan. CONSTITUTION:A discrimination processing means 4 makes the area discrimination by means of the forward scan of the prescan, saving the result in a memory 6. With the backward scan of the prescan, the contents of the memory 6 is read to save it while making the backward discrimination. The copy scan, especially the area recognition color data are taken to correct the contents of the memory 6 to be outputted as area data. Thus, the area discrimination can be completed within the prescan and the copy scan so that the processing time can be shortened without requiring the excess area discrimination time. Further, expensive circuits such as CRT controllers can be made unnecessary, resulting in decreasing the cost.
