Title: Removal of scale from boiler
Inventor: NAKAMUTA TANJI
IPC: F28G9/00
Filed: 1990-04-11
Abstract: PURPOSE:To enable a cleaning stage in a pipe or a boiler system to be substantially simplified by a method wherein pickling inhibitor is added to water containing carbonic acid gas, kept or circulated in the boiler and adhered scales are removed. CONSTITUTION:After resolving scales with water containing carbonic acid gas, the scales are discharged out of a system and at the same time a steel material such as an evaporation pipe or the like is prevented against corrosion with carbonic acid gas by pickling inhibitor. As the pickling inhibitor, organic compound or acetylene compound containing nitrogen, sulfur and oxygen or the like which are usually applied for hydrochloric acid or sulfuric acid can be used. However, even though the discharging of the scales after their resolving operation is not sufficient and a small amount of scales is left in the system when the boiler is operated, quinoline (C9H7N), aniline (C6H5NH2) and these derivatives or nitrogen compound not containing sulfur causing a stress corrosion crack or a local corrosion or the like of a boiler steel material are preferable. Added concentration of the pickling inhibitor is preferably 0.1 to 0.5%.

Title: Ball launcher of motorized pinball machine
Inventor: TSUCHIMOTO RYOICHI
IPC: A63F7/02
Filed: 1990-04-10
Abstract: PURPOSE:To certainly detect the fact that a player grips a ball-launching handle, to allow a pinball machine to stably launch balls without mal-functioning by detecting a resonance electric current that flows through a resonance circuit in which a pair of touch electrodes and a resonance coil are inserted in parallel. CONSTITUTION:When a player grips a ball launching handle, the electrostatic capacity between touch electrodes (a) and (b) increases due to the electrostatic capacity of a human body. When the resonance frequency determined by the capacity between the touch electrodes and a resonance coil 39 coincides with the oscillation frequency output from a first oscillation circuit 33, a large resonance electric current flows through a resonance circuit 34 so that the output level from an output terminal of an electric current level detecting circuit 35 is changed from 'L' to 'H' level, and the output is input to an input terminal of an AND circuit 37. A clock signal with a constant cycle is output from a second oscillation circuit 36 to the other input terminal of the AND circuit 37, and pulse signals, which turn on and off repeatedly synchronizing with the constant cycle clock signals that are output from the circuit 38, are transmitted to a dividing circuit 38.

Abstract: PURPOSE:To stably stop a synchronous generator without setting generation plant equipments in an overexcited state by abruptly exciting the generator with an overexcitation detection signal of the generator and a closure signal of a parallel breaker, and switching to the prescribed excitation control operation after the prescribed time limit. CONSTITUTION:When an emergency stop command is outputted during the operation of a main machine, a stopping device of the main machine is operated, and a parallel breaker 7 is released.

IPC: F23C15/00
Filed: 1988-04-19
Abstract: PURPOSE:To attempt to make clean the discharged gas by providing an oxidizing filter to the tip-end ignition section of a straight-pipe combustion chamber and letting the discharged gas in combustion pass through the oxidizing filter to oxidize and remove by the oxidizing filter poisonous gases contained in the discharged gas in combustion such as unburned gases.

In a flame propagating combustion action in which charging and discharging, ignition, combustion, and fire extinguishing area repeated in cycle continuously the discharged gas in combustion in the preceding cycle is pushed out by the charged gas to discharge the discharged gas through a discharging pipe 7 out of the device during the charging action to supply a mixture of gases to the combustion chamber 1 in the next cycle. The oxidizing filter 3 is heated by the passage of the discharged gas in combustion through it and at the same time the filter 3 oxidizes poisonoue gases such as unburned gases, products in combustion, etc., which are contained in the discharged gas in combustion to make exhaust gases clean and discharge them through the discharging pipe 7 out of the device. Accordingly no discharged gas containing poisonous gases such as carbon monoxide is discharged out of the device.

Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To improve productivity by attaining a detent for receiving a reaction in screwing a bolt into the reaction receiver with a simple constitution. SOLUTION: In this vacuum booster, a flange part 17B for a reaction receiver 17 for receiving the reaction from a reaction disc 15 is set to a hexagonal shape. Therefore, when a bolt 21 is screwed into the reaction receiver 17, the flange part 17B can be locked by being held by a general jig such as a torque wrench. In this case, a boring process is eliminated so as to improve the productivity for that. No use of a weak strength jig dispenses with a careful work so as to improve workability, improve productivity, and reduce the cost of the device.
