On the other hand, the system including integrating part 14C, comparison part 14D and control  part 14E generates control signal (q) indicating that some disturbance is detected in the period of  signal (g). In case no disturbance is detected in the period of(g), gate G 3  is opened; while G 3  is  closed when the disturbance is detected respectively. Thus, output 14S of circuit 14 contains the  voltage corresponding to the period disturbance, and accordingly the voltage output corresponding to the basic wave period can be obtained. And the miscontrol can be prevented for the  vairable frequency oscillator which is controlled by output 14S.

Filed: 1984-03-23
Abstract: PURPOSE:To provide an electrolyte which is so appropriate to a nonaqueous- solvent cell that a large voltage drop at the initial stage of large-current discharge in reduced, by adding pieces or powder of lithium to a solution containing thionyl chloride as the main constituent, then filtering the mixture, and dissolving a vinyl polymer in the filtered liquid. CONSTITUTION:1.2mol/l of AlCl3 is dissolved in SOCl2. 1.2mol/l of LiCl is then dissolved in the solution. After that, about 2g of lithium pieces are added to 100ml of the solution. The mixture is stirred for 3 days. The mixture is thereafter filtered to remove the liquid of the lithium pieces. 0.5g/l of a copolymer (copolymerization ratio of 9:1) of vinyl chloride and vinyl acetate is dissolved as a vinyl polymer in the filtered liquid so that an electrolyte is provided. When a thionyl-chloride cell A employing the electrolyte is discharged through a fixed resistance of 30OMEGA, it is understood that the cell A which is an embodiment of the present invention undergoes a smaller voltage drop at the initial stage of discharge than other cells B, C, D and is therefore excellent in initial discharge characteristics, as shown in the drawing.

Title: Ceramic filter for removing combustible fine particle
Inventor: NARITA YOSHINORI
IPC: F01N3/02
Filed: 1982-04-03
Abstract: PURPOSE:To remove filtered combustible fine particles efficiently by burning them while keeping the high filtering capacity of a filter, by applying an electric current to the filter's own body to generate heat. CONSTITUTION:A waste gas from an engine containing fine carbon particles passes through an exhaust manifold and a connecting pipe 18 without causing any change, and flows into an inlet side of a ceramic filter for removing combustible fine particles from the upstream direction F. Next, the waste gas passes through a filtering body 1 and is discharged from the exit side to the outside of a filter 15, and then flows through a connecting pipe 19 to the direction B of an exhausting pipe, etc. on the downstream. When the filter 15 is heated and the temperature of the fine carbon particles is raised to the ingition temperature by the application of an electric current between both electrodes 3 and 4 and the heat generation of a heat generating resistive body 2, the carbon particles burn and vanish, then a pressure drop caused by the clogging of filter due to the deposition of stuck carbon is prevented.

Abstract: PURPOSE:To improve comfort in riding and running stability by changing over variable throttles to sudden attenuation when the pitching vibration of a body has exceeded a threshold value, and to smooth attenuation when said vibration has dropped below a predetermined value, respectively. CONSTITUTION:When the displacement of a suspension lock cylinder 10 has been detected with a displacement detector 13 and inputted to a controller 20, this controller 20 detects the pitching vibration of a body on the basis of a displacement signal and makes judgement as to the existence or the non-existence of necessity for vibration control through comparison with a predetermined value. Namely, when the vibration has exceeded the predetermined value, variable throttles 17 and 18 are changed over to a sudden attenuation side and a timer is actuated. And the sudden attenuation condition has been kept until an elapse of timer actuation. Also, when the vibration has dropped below the predetermined value within the timer actuation time, the timer is reset and the throttles 17 and 18 are changed over to smooth attenuation. According to the aforesaid constitution, comfort in riding and running stability can be improved.
