Title: Quantity measuring instrument for injected fuel
Inventor: TSUZUKI NAOYUKI
IPC: G01F9/00
Filed: 1985-12-26
Abstract: PURPOSE:To enable a fuel injection quantity to be satisfactorily measured by providing a fuel volume detector, fuel injection quantity calculating means and fuel discharge means. CONSTITUTION:A fuel injection quantity measuring instrument is constituted by a fuel volume detector 1, a discharge container 3 for discharging an injected fuel, a measuring controller 5 for measuring and controlling a fuel injection quantity, a valve drive unit 14 for opening and closing discharge valves 7-10 and a drain discharge valve 12 and the like. The quantity of the fuel injected into an injection chamber 36 is detected by means of the displacement of a diaphragm (DF) 31 provided so as to separate the injection chamber 36 and a back pressure chamber 37 from each other. When the fuel is injected into the injection chamber 36, the DF 31 is displaced according to the injected fuel quantity, that is, a fuel volume, but the pressure of the injection chamber 36 is not changed in spite of the displacement of the DF 31. Nevertheless, the fuel injection quantity is obtained by the controller 5 based on the peak value of the DF displacement quantity detected by displacement quantity detecting means after the fuel injection. The discharge container 3 is so operated as to quickly discharge the fuel of the quantity corresponding to the injected fuel quantity from the injection chamber 36 after the measurement of the fuel injection quantity.

Title: Brush
Inventor: TSUTSUMI KATSUJI
IPC: A46D1/00
Filed: 1990-11-01
Abstract: PURPOSE:To sufficiently wash the deposits on the surface of articles having rugged surfaces by fixing abrasive grains via binder layers on the surface of twisted wires or stranded wires of flexible wires and fixing many brush wires to a rotating body. CONSTITUTION:The cylindrical brush A fixed with the many brush wires 1 formed by doubling and twisting the flexible wires consisting of cotton yarn, synthetic fiber yarn, soft nylon, etc., is formed by incorporating the abrasive grains 2 of molten alumina, silicon carbide, artificial diamond, etc., into the binder layers 3 consisting of liquefied rubber or resin or adhesives, passing and sticking the brush wires therein, and solidifying the binder layers 3. The binder layers 3 intrude into recessed parts 4 formed in the twisting spaces of the twisted wires and, therefore, the abrasive grains 2 are strongly fixed at a high density to the brush wires 1. The thickness of the binder layers 3 is set at about 1/2 to 2/3 the diameter of the abrasive grains 2 and the abrasive grains 2 are held partly exposed to the outside. The brush wires 1 having flexibility are deflected by their resilience and move by following up the rugged surface B. The front ends of these wires intrude well into the recessed parts as well. The deposits C are thus smoothly scraped off.

Title: High zirconia-based hot-melt casting refractory
Inventor: ISHINO TOSHIHIRO
IPC: C04B35/484
Filed: 1990-11-06
Abstract: PURPOSE:To obtain hot-melt casting refractories having high reliability wherein a flaw of one part and heat resistant cycle resistance are improved by constituting this refractories in which ZrO2, SiO2 and Al2O3 are incorporated and any of P2O5, P2O3 and CuO is not incorporated as the chemical component. CONSTITUTION:High zirconia-based hot-melt casting refractories incorporate 90-95wt.% ZrO2, 3.5-7wt.% SiO2 and 1-3wt.% Al2O3 and do not incorporate any of P2O5, P2O3 and CuO as the chemical component of refractory. As the preferable chemical component of the above-mentioned refractories, 3.5-6wt.% SiO2 and 1.3-2.5 wt.% Al2O3 are incorporated. As the applications of the refractories, these are utilized for melting of glass. Corrosion resistance for molten glass is made good as ZrO2 component in the refractories is made plenty. ZrO2 is regulated to >=90% from this point. However when ZrO2 is made more than 95%, matrix glass is reduced and a crack is easily caused. It is difficult that the refractories free from the crack are obtained by casting.

Title: Method for monitoring physical amount
Inventor: HORI TAKAHIRO
IPC: G01K3/10
Filed: 1997-10-30
Abstract: PROBLEM TO BE SOLVED: To exert high usefulness and reliability by delaying each start of monitoring by a shorter sampling time than a monitor time. SOLUTION: A difference (absolute value) between a data BFn of a previous monitor time ΔT and a data BF0 of a buffer 0 is compared with a monitor width SV. When the difference (absolute value) of the data BFn of the previous monitor time ΔT and data BF0 of the buffer 0 is smaller than the monitor width SV, the process is returned. On the other hand, when the difference (absolute value) of the data BFn of the previous monitor time ΔT and the data BF0 of the buffer 0 is not smaller than the monitor width SV, a change amount ΔPV is calculated from the lapse of the monitor time ΔT thereafter, and a warning signal is generated. A temperature rise of a bearing metal is accordingly restricted by a warning buzzer, a warning lamp, etc., thereby preventing seizure of the bearing metal.
