Title: Etching method of inorganic thin film
Inventor: NIWA KATSUHIRO
IPC: H05K3/06
Filed: 1993-07-02
Abstract: PURPOSE:To enable an inorganic thin film to be lessened in etching time and side etching by a method wherein the inorganic film is etched with etchant high in etching rate using a pattern layer formed on it as a mask and then etched again with etchant lower than the former etchant in etching rate. CONSTITUTION:An inorganic thin film such as a silicon wafer is etched using a pattern layer of photoresist or the like formed on the inorganic thin film as a mask. At this point, hydrofluoric acid water solution, iron chloride water solution, sulfuric acid water solution, ammonium persulfate water solution, or chromic acid water solution is used as etchant. Moreover, an etching operation is carried out with echant high in etching rate first, and a following etching operation is carried out with etchant lower in etching rate than the former etchant. By this setup, an inorganic thin film can be lessened in etching time and side etching even if the film is thick.

Title: Dispersion plate supporting structure for fluidized bed furnace
Inventor: KAWAI MICHIHIRO
IPC: F27B15/10
Filed: 1998-06-12
Abstract: PROBLEM TO BE SOLVED: To reduce facility cost significantly by supporting a dispersion plate on a pole fixed to the iron skin of a fluidized bed furnace while penetrating it vertically thereby reducing the weight of the dispersion plate. SOLUTION: A dispersion plate 4 provided in a fluidized bed furnace F is supported by a pole 12 fixed to the iron skin 1 of a fluidized bed furnace F while penetrating it vertically. Since a load acting on the dispersion plate 4 in the vertical direction is born surely by the pole 12, sufficient strength can be kept even if the dispersion plate 4 is made thin. The post 12 is cooled by cooling medium passing through a cooling medium passage formed in the post 12.

Title: Secondary air blowing method for incinerator
Inventor: IJIMA OSAMU
IPC: F23G5/44
Filed: 1990-06-21
Abstract: PURPOSE:To generate a swirl of secondary air around a compressed air so as to improve an efficiency of a secondary combustion of non-burnt substance by a method wherein the secondary air is blown into a center part of the incinerator near an outlet port of the incinerator and concurrently the compressed air of which volume is smaller than that of the secondary air is blown from an inside part of the secondary air toward the center of the incinerator. CONSTITUTION:Secondary air 19 is supplied from a secondary air blower 14 through a secondary air pipe 13. The air is blown from a blowing mouthpiece 12 toward a center of the incinerator near the outlet port of the incinerator. Concurrently, compressed air 20 is supplied from an air compressor 17 through a flow rate adjusting valve 16 and a compressed air pipe 15 and then the compressed air is blown from inside part of the secondary air 19 toward the center of the incinerator through a nozzle 18. At this time, an amount of blowing the compressed air 20 is adjusted in advance by the flow rate adjusting valve 16 in such a way as it becomes properly a smaller amount than that of the secondary air 19. In this way, the secondary air 19 blown into the incinerator is increased in its flow speed by the compressed air 20, but also becomes a swirl around the compressed air 20. Due to this fact, even if the blowing pressure of the secondary air 19 is not increased, mixing with the non- burnt part of the combustible gas in the discharged gas with the secondary air 19 is improved.

IPC: B24B19/00
Filed: 1979-12-19
Abstract: PURPOSE: To prevent the dimensional ununiformity of both sides in a machine which grinds the cage window of a uniform motion ball joint by simultaneously grinding both the sides of a number of cage windows using a separate wheel.  
     CONSTITUTION: A number of cage windows for a cage (W) are sequentially indexed by an indexing device 45 at the position which corresponds to the first and second wheels Ga and Gb. Then the first and second wheels Ga and Gb are mutually cut-advanced by the first and second cut devices 66a and 66b in the reverse direction. Each one side of all the cage windows are sequentially ground by the first wheel Ga and each of their other sides ground by the second wheel Gb. In other words, while the work by the first wheel Ga is being performed, the second wheel Gb is ground and cut against the first wheel Ga in the reverse direction and completes the grinding of another side of the cage windows. At described above, another side can high precisely be ground on the same surface without the dimensional ununiformity of the cage windows.

Title: Zinc alloy for fuse
Inventor: ISHIBASHI YUKIO
IPC: C22C18/02
Filed: 1989-06-29
Abstract: PURPOSE:To provide the above alloy which has high strength and is improved in heat resistant characteristic and durability by adding a specific ratio of Al or Mg to a Zn-Cu-Ti alloy having a specific compsn. CONSTITUTION:This zinc alloy for fuses contains, by weight %, 0.3 to 0.6 Cu, 0.1 to 0.3 Ti, and 0.01 to 0.08 >=1 kinds of Al and Mg and consists of the balance Zn. This alloy has the excellent durability and high reliability and is further improved in workability, weatherability, mechanical characteristics, ease of assembly, heat resistance, etc. While Cu in this alloy is required to be incorporated at the lower limit or above in order to obtain the adequate strength in terms of the ease of assembly and workability, the alloy is liable to crack at the time of rolling in excess of the upper limit. Ti is effective for the stabilization of fusing time in addition to the improvement in rollability and high-temp. creep characteristic. The effect thereof is small it the content thereof is below the lower limit and the melting of the alloy is difficult and the effect of the addition is satd. if the content exceeds the upper limit. Both Al and Mg improve the strength and workability at above the lower limit but problems remain in the heat corrosion resistance at the time of assembly if the content exceeds the upper limit. Further, the material surface is oxidized in the process for soldering and assembling by a calcination furnace and the stickability of solder is degraded in such a case.

IPC: F16J9/06
Filed: 1980-11-27
Abstract: PURPOSE:To prevent reduction of output and the piston beating noise accompanied by oscillation of the piston by forming in ordinary times a little gap between a piston ring and an expander ring, in the apparatus having both rings in the ring groove on the outer peripheral surface of the piston. CONSTITUTION:The outer peripheral piston ring 4 which contact with the inner peripheral surface of a cylinder 1 and the expander ring 5 which is bent in wave form are installed in the ring groove 3 formed on the outer peripheral surface of the piston 2 which is fitted in the cylinder 1.

Inventor: SUZUKI TAKEFUMI
IPC: F24H1/18
Filed: 1994-06-24
Abstract: PURPOSE:To enable hot water to be optionally taken out at any time by a method wherein an inner part of a heating tank is divided into a right segment and a left segment by a partition plate, one segment is applied as a heating part having a heater and a temperature sensitive opening or closing valve stored therein and a hog water guiding pipe connected thereto, and the other segment is applied as a hot water storing part having a water guiding pipe and a water supplying pipe connected to a hot water storing tank placed at the lower- most stage, respectively. CONSTITUTION:In the case that hot water stored in a heating part 9a of a heating tank 9 is sufficiently high, an opening or closing valve 11 is kept closed, so that water advanced from a water supplying pipe 13 into a hot water storing part 9b passes through a water feeding passage 36, advances from a lower part within the heating part 9a so as to push out the hot water within the heating part 9a into a hot water guiding pipe 10 through the opening or closing valve 11 and further into a hot water feeding plug 16 through a hot water feeding pipe 15. Water advanced from the water feeding pipe 13 has a certain difference in density in respect to either hot water within the hot water storing part 9b or hot water within the heating part 9a, so that they may not be mixed from each other, but kept at their separated states. As described above, in the case that the hot water is stored from above the hot water storing tanks 83 to 81 and the hot water is taken out, the hot water is taken out from above, so that it is always possible to an instant hot water feeding operation.
