Title: Fuel-injection type engine
Inventor: KAWACHI MASAYUKI
IPC: F02D41/34
Filed: 1985-06-04
Abstract: PURPOSE:To heighten a degree of control accuracy in a fuel flow rate, by controlling an injection valve inside a cylinder for feedback on the basis of an oxygen sensor output, in case of a device which installs each fuel injection valve in the cylinder and a suction passage and drives one side or both fuel injection valves according to an engine driving state. CONSTITUTION:A first fuel injection valve 21 is installed in a cylinder of an engine 1, while a second fuel injection valve 23 is installed in a suction passage 22. These fuel injection valves 21 and 23 drives and controls either or both by a injection valve driving device 24 according to a driving state of the engine 1. That is to say, when the engine 1 is warming up as well as when it is high load, a second fuel injection valve 8 is driven but at the time of light load, a first fuel injection valve 7 is driven. And, when a drive of the first fuel injection valve 7 is detected by a detecting device 25, the first fuel injection valve 7 is made so as to be feedback-controlled on the basis of output of an exhaust gas oxygen content sensor 28 by a feedback controlling device 26.

Title: Curved surface automatic welding device
Inventor: GOTOU HISAO
IPC: B23K9/12
Filed: 1979-09-19
Abstract: PURPOSE: To carry out a curved surface welding, by maintaining a certain relation of the plane position to the engaging means which gives a correction to the inclination of the object to be welded with the output signal of the inclination detector and the detector itself and regardless of the travelling direction of the welding machine.  
     CONSTITUTION: The welding device consists of the following component units: engaging means 4W6 which hook vertically the object 2 to be welded; the driving unit which drives two or more units of said engaging means and then varies the inclination of the object 2; the welding machine 7 which is travelling; the gyroscope 30 which gives a high-speed revolution to the gyrowheel by a driving unit and then holds the support component of the detector 10 in the fixed direction; the inclination detector 10 which detects the inclination of the object 2; and the control unit which gives a proper driving to the driving unit respectively. For instance, when the machine 7 travels the direction X 1 WX 2  to give an welding to the convex and curved object 2, the detector 10 detects the inclination of the object 2 to then deliver the inclination detection result. And this output is transmitted to the driving unit via the control unit. The driving unit actuates the engaging means to give a correction for the object 2 to a fixed inclination.

Abstract: PURPOSE: To easily and efficiently remove pollutants by providing the inside of a small-sized outside box having an inlet and outlet for air with means for deionizing the particles and vapor in the air and neutralizing the positive charge possessed by flue dust and toxic materials. CONSTITUTION: The air is taken in from a filter 32 of the inlet 12 and at the time of the air passes the inside of the outside box 10 after larger dust is removed, the air is subjected to exposure of the formation of ozone by the high voltage partially applied from grids 48A, 48B.

Title: Water content monitoring apparatus
Inventor: UETAKE NAOTO
IPC: G01R33/44
Filed: 1986-05-28
Abstract: PURPOSE:To enable the monitoring of water content in a nondestructive manner being distinguished from hydrogen in an organic material by determining the area or a value of a peak with the half-value width less than 10Hz in a nuclear magnetic resonance absorption spectrum. CONSTITUTION:A magnetic field is applied to powdery material 3 to be measured being fluidized through a piping 2 from a magnet 1. When a radio wave within a nuclear magnetic resonance frequency of hydrogen nuclus is made incident on the powdery material 3 in a magnetic field from a transmitting coil 4, a resonance absorption takes place by the hydrogen nuclus to cause a change in the direction of the magnetization, which is detected with a receiving coil 5 and amplified with a receiver 7 to be sent to a data processor 8. Generally, the half-value width is less than 10Hz in the nuclear magnetic resonance absorption spectrum of the hydrogen nuclus of water and hence, water can be distinguished clearly from an organic solid, which is more than several tens of Hz. Therefore, the area or value of a peak with the half-value width less than 10Hz is determined with a processor 8 in a nuclear magnetic resonance absorption spectrum of the powdery material 3 as function of the frequency obtained from the output of the receiver 7 and multiplied by a fixed coefficient to calculate the water content of the powdery material 3.

According to difference of specific gravities, the oil containing much bubbles gathers around a center of the swirl, while the oil containing less bubbles gathers along an outer edge of the swirl. The oil containing much bubbles flows into bubble removing ports 5 and the bubbles are removed from an upper end of a tube. The oil containing less bubbles is introduced outside from oil introducing ports 4. An oil pan is divided into an upper stage 8 and a lower stage 9. The oil is fed to the oil passage 7 together with circulating oil, for circulation. Excellent bubble removing effect is obtained, accordingly.
