Title: Protective construction method against chemical injection
Inventor: TAKEDA HIROSHI
IPC: H02G1/06
Filed: 1990-03-14
Abstract: PURPOSE:To protect a duct line from chemical injection by sending a protective liquid into the duct line from the leading end of a liquid feeding tube so as to fill up part of the duct line including a chemical injection place with the protective liquid and circulating the protective liquid. CONSTITUTION:Tubes 12 are inserted from the side of a manhole 1 located at the lowest place until the leading ends of the tubes 12 pass by a chemical liquid injecting place. A submersible pump 18 pumps up water 20 from the bottom of the manhole 1 and sends the water 20 to each tube 12 through a flowing water branching tube 19. As a result, the water 20 flows into holes 7 and 7 from the leading end of each tube 12. The water 20 is discharged into the manhole 1 while it passes by the chemical liquid injection place. Accordingly, the holes 7 and 7 at the chemical liquid injecting place are filled up with the water. Since no water flows to a higher level, on the other hand, the water does not flow to the parts of the holes 7 and 7 higher in level than the front ends of the tubes and this duct line 3 is partially filled up with the water.

Abstract: PROBLEM TO BE SOLVED: To correctly detect acoustic noise from a valve, a header, and the like so as to be able to insure stable flow detection, by obtaining frequency of the signal component of a vortex flow signal by a computing means based on instantaneous frequency and frequency spectrum. SOLUTION: A phase shift means 301 shifts the phase of a vortex flow signal from a sensor 1 by 90 deg., a division means 302 divides the vortex flow signal by the shifted signal. A phase detecting means 303 obtains arctan of the divided signal, and detects the phase of the vortex flow signal. A differentiation means time-differentiates the phase so as to compute instantaneous frequency, and a high speed Fourier conversion means 305 frquency-analyses the vortex flow signal. A computing means 306 obtains frequency of the signal component of the vortex flow signal based on the instantaneous frequency computed by the differentiation means and the frequency spectrum obtained by the high speed Fourier conversion means 305, and when the frequency changes discontinuously, it is judged that noise is generated.  From change of the frequency spectrum at the time point, the true signal component is extracted.

IPC: F02D13/02
Filed: 1989-03-15
Abstract: PURPOSE:To prevent the occurrence of knocking by providing a load adding means for applying the external load to an engine under a predetermined low speed low load condition detected by a running condition detecting means. CONSTITUTION:A control unit 27 for an engine E judges the running condition from the output of an air flowmeter 12 and the rotational frequency N of the engine to set an intake-exhaust overlap amount small under a low speed low load condition and large under the other conditions for the prevention of knocking. On the other hand, under the idling condition, the idle rotational frequency is controlled to be a set value. Under a predetermined low speed low load condition, an electromagnetic clutch 25 is connected to operate a supercharger 14. When the external load is added to the engine E, the rotational frequency N of the engine tends to be reduced. However, an intake amount is correctively increased by opening an ISC valve 24 so that the idle rotational speed reaches a set value. Thus, the stability of the engine can be ensured.

Filed: 1990-03-16
Abstract: PURPOSE: To make it possible to bring about a change of the degree and direction of polarized light by using an optically active medium to be subjected to the inversion of the direction of the polarized light by a given temp. CONSTITUTION: The optically active medium to be subjected to the inversion of the direction of the polarized light by the given temp. is used. The polarized light is separated to circularly polarized components H1 and H2 when the medium is maintained at the level immediate below the temp. near the spiral inversion temp. of CLC(cholesteric liquid crystals). H1 is transmitted and H2 is reflected. The transmitted beam passes a quarter-wave plate 12 and is emitted as the light linearly polarized at a polarization angle θ1 with the perpendicular. When the intensity of the incident beam increases, the temp. of the CLC medium 10 increases until the temp. exceeds the spiral inversion temp. TH. The beam reflected at this time is H1 and H2 passes the quarter-wave plate and is plane polarized at an angle θ2 with the perpendicular.  As a result, an analyzer 14 is capable of blocking the one emerging beam and allowing the transmission of the other if a suitable adjustment is executed.
