Title: Fuel injection equipment of internal-combustion engine
Inventor: SHINGUU KENJI
IPC: F02D1/02
Filed: 1983-08-05
Abstract: PURPOSE:To hold the rate of fuel injection always at its optimum level by equipping a fuel injection device with an oil-hydraulic timer to correct the changing ignition timing, wherein the injection amount is controlled by the relative rotation of a plunger with a ring valve while the ignition timing is controlled by displacement of the plunger of said valve in the axial direction. CONSTITUTION:A fuel injection pump 1 has a plurality of single cylinder units 4, each of which presses forward the fuel through the action of a plunger 16 reciprocated by a cam shaft 19, and the relative rotation and axial directed displacement of a ring valve 18 fitted on said plunger 16 with respect thereto will provide adjustment of the amount of fuel injection and the rate thereof, respectively. Said axial directed displacement of ring valve 18 is performed by an injection rate adjustment rack 25 and an eccentric pin 26. At the exterior end of the above-mentioned cam shaft 19, an oil-hydraulic timer is mounted, which shall conduct a specified delay or advance of the ignition angle by changing the rotational phase angle between the cam shaft 19 and the drive shaft on engine side. This will accomplish a feedback control in compliance with the amount of change in said adjustment rack 25 as well as the operating conditions of the engine.

IPC: E21D11/00
Filed: 1994-06-27
Abstract: PURPOSE:To automatically monitor the leakage of a lining material from a formwork and whether the lining in the formwork is normally hardened or not from a remote location. CONSTITUTION:The zoom and direction of an infrared camera 7 are operated by a camera control device 8, a monitor position is photographed by the infrared camera 7, the image data thus obtained are fed to a thermal image processing device 10, and the image data are thermally image-processed to obtain the heat distribution of the monitor position. Since a lining material 1 filled between an inner formwork 3 and an outer formwork 4 generates heat during hardening, whether there is an abnormality or not can be known when the heat distribution of the monitor position is obtained. When there is a portion near the end section of the formwork having an abnormally high temperature as compared with the formwork, it is known that a leakage 1' of the lining material 1 occurs at this portion. When the temperature of all formworks is nearly constant and there is no portion having a low temperature in particular, it is known that the hardening of the lining material 1 is normal.
