Title: Operating method for hydraulic rotary compressor of pressure switch type
Inventor: OOBA TAKAFUMI
IPC: F04B49/02
Filed: 1981-12-11
Abstract: PURPOSE:To aim at making oil lock preventable at the time of starting a compressor, by keeping up a solenoid valve in a state of closure for a limited time after the compressor restarts, when the pressure inside an oil separator tank goes down to the extent of its lower limit. CONSTITUTION:When a solenoid valve SOL closes, lubricating oil fed so far to the compression part of a compressor proper 1 is stopped. Simultaneously, a relay timer RT2 is energized with current. Like this, since the feed of lubricating oil (b) is intercepted for a limited time before the compressor proper 1 stops, most of the lubricating oil will not remain there in time of stoppage of the compressor proper and the oil is discharged into an oil separator tank 5. Accordingly the compressor proper 1 stops smoothly. In this way, not only an impact given to the compressor proper 1 can be eased but also the possible occurrence of oil lock in time of restarting can be relieved.

Title: Reducing agent injecting device for denitrifying device
Inventor: YAMAGUCHI TETSUJI
IPC: B01D53/34
Filed: 1995-08-03
Abstract: PROBLEM TO BE SOLVED: To reduce the electric power consumption of a reducing agent injecting device for the denitrifying device of a boiler power plant by using hot air as the gas of the reducing agent. SOLUTION: The waste gases from a boiler 1 enters a denitrifying device 2 where NOx is removed from the gases. The gases are then discharged from a chimney. The air from a forced draft fan 10 is heated up by the waste gases from the chimney by a preheater 3 and is introduced into the boiler 1. The hot air of 250 to 300 deg.C is extracted through a piping 13 at the outlet of the air preheater 3 by an induced draft fan 5 and is sent to an evaporator 7 where the aq. reducing agent soln. introduced from a reducing agent tank 9 by a supply pipe 6 is sprayed and is evaporated and diluted. The vapor passes a supply pipe 12 where the vapor is cooled down to about 130 deg.C. The vapor is mixed into the exhaust gases in a flue from a distributing header 8 and the NOx is removed by the denitrifying device 2.  The driving power of the induced draft fan 5 is merely necessitated for the evaporation and injection of the reducing agent and the electric power consumption is reduced.

Title: Air-fuel ratio controller for engine
Inventor: NISHIJIMA TSUYOSHI
IPC: F02D41/00
Filed: 1985-09-10
Abstract: PURPOSE:To suppress the influence of noise by constituting an oxygen sensor from two detecting pieces consisting of n-type and p-type metal oxide semiconductors and controlling the air-fuel ratio by using the output values obtained through the sampling treatment between ignitions. CONSTITUTION:An oxygen sensor is constituted of the first and the second detecting pieces consisting of n-type and p-type metal oxide semiconductors, and in correspondence with each characteristic, when the air excessive rate lambda=1, the air fuel ratio is controlled by the n-type output value, and in the lean region where lambda>1, the air-fuel ratio is controlled by the synthetic value, of the both outputs, and in the rich region where lambda<1. the air-fuel ratio is controlled by the p-type output value. In order to suppress the influence of the noise due to ignition, the output values of the both detecting pieces which are sampling-treated between ignitions are used, and since, when the synthetic value is sued, the influence of noise is offset, by the synthesis, sampling is performed independently of ignition timing, and calculation is carried out. Therefore, the load of a control unit through the lapse of time can be reduced exceedingly, suppressing the influence of the air-fuel ratio control due to the noise.

Title: Terminal conductor of vacuum switch
Inventor: OSHIRO TAKASHI
IPC: H01H33/66
Filed: 1997-07-24
Abstract: PROBLEM TO BE SOLVED: To reduce the number of components and enhance cooling by making the correctional shape of a terminal conductor nearly T-shaped, supporting both ends of the terminal conductor with an insulating frame, and bringing the fixed side end of a vacuum valve into contact with its flat central part so as to conduct current. SOLUTION: A fixed side terminal conductor 15 is composed of a flat part 15a straddling between a front mounting part 2a and a rear mounting part 2b, a nearly cylindrical led-out part 15b that is led out from an insulating frame 2, and a reinforcing part 15c whose cross-sectional shape containing the almost flat part 15a is nearly T-shaped and which is located on the upper surface of the almost flat part 15a and stretching in the axial direction of the terminal conductor 15. Since the cross section of the terminal conductor 15 is almost T-shaped, its strength becomes high and it also has a current-conducting function. Thereby, the number of components can be reduced.  In addition, because the T-shaped reinforcing part 15c is provided, the surface area is so large that the effect as a heat dissipating fin is enhanced; thus, the generated heat in a vacuum valve 1 is transmitted through a vacuum valve-retaining part 15d to the terminal conductor 15 and is radiated from its surface so that large current can be conducted.

Abstract: PROBLEM TO BE SOLVED: To prolong the service life of a punch by firstly giving a recessed part having the depth of value calculated with a specific calculating equation to a sheet blank with a punch and thereafter, cutting off the sheet blank with the other punch. SOLUTION: The shifting of the punch 2 forms only the recessed part 9 to the sheet blank 1, i.e., sets so as to be possible to deform without cutting off the sheet blank 1. In the case of using E for the thickness of the sheet blank 1, the depth (p) of the recessed part 9 is made to the range of 0.416(1-e<-1.279> E)-0.05E to 0.416(1-e<-1.279> E)+0.1E. After forming the recessed part 9 to the sheet blank 1, firstly, this sheet blank 1 is cut off with the edge part to the direction of the recessed part 9 and the same direction as this direction. By this method, the two different punches can be adopted and the first one is exclusively used to the process for forming the recessed part of the sheet blank 1, and the second one is exclusively used to the process for cutting off after forming the recessed part.
