Title: Fuel control device of engine
Inventor: AIGA SHOICHI
IPC: F02D41/18
Filed: 1990-03-09
Abstract: PURPOSE:To make stable air-fuel ratio control possible by providing a valve timing variable means and a moderation correcting means for moderation- correcting an intake air amount detection value and controlling a correction amount in such a way that the longer a valve opening period of valve timing is the larger the moderation correction amount is increased. CONSTITUTION:Valve timing switched by outputting a high speed cam select command to a valve timing changing mechanism from an ECU 9 when an engine speed by an engine speed sensor 15 is in a high speed cam switching reference engine speed or more, and outputting a low speed cam select command in the same way, when the engine speed is in the above-mentioned reference engine speed or less. Air-fuel feedback control is performed for correcting a basic fuel injection amount, determined based on an intake air amount by an air flow meter 2, and the engine speed, by an air-fuel ratio deviation. The air intake amount at this time is moderation-corrected in accordance with an operational condition, but this moderation correction is controlled in such a way the longer the valve opening time of valve timing is the larger the moderation correction amount is increased in comparison with the shorter opening time.

Filed: 1987-03-16
Abstract: PURPOSE:To enhance particle size resolving power and to measure even impure fine particles having a small particle size, by intermittently irradiating the fine particles in a flowing fluid with laser beam so as to traverse the flow of the fluid. CONSTITUTION:A fluid flows through a sampling cell 1 from below to above and laser beam (b) is allowed to cyclically and intermittently irradiate the fluid so as to traverse the flow (f) of the fluid. When fine particles 20 flow through the laser beam (b) from below to above, the reflected beams from the fine particles 20 as reaction beams become as follows. That is, the intensity distribution of the cross-section of the laser beam (b) in the longitudinal irradiation direction at times t1, t2... is built up at the central part thereof and, therefore, the intensity of the reflected beams when said beams pass the central part is highest and the intensities thereof at both upper-and-down end parts thereof are weak. That is, the pulse train of the reflected beams with intensity (e) is generated. Therefore, by appropriately processing the output of the obtained pulse train, the particle size of the fine particles 20 contained in the fluid and the number of said particles can be calculated.

Title: Vane for hydraulic motor
Inventor: TOYOSHIMA SHIGERU
IPC: F03B1/00
Filed: 1989-03-13
Abstract: PURPOSE:To provide easy manufacture and reduction in size, and continuous drive through only one hydraulic pipe by forming the shape of the vane of a hydraulic motor into a semi-cylindrical shape. CONSTITUTION:When pressure oil enters a casing 3 from a hydraulic inflow port 2, the oil discharged from a semi-cylindrical shape 4 works upon the semi- cylindrical shape groove 6 of a vane 5 to obtain power. The construction of the vane is simple, which is especially used for a small type motor. As a result, it serves for oil pressure rather than oil amount with residual pressure, which makes a hydraulic pump used small and permits use in a low power source such as the auxiliary machine for a tool machine. As an example, it is possible to drive plural hydraulic motors continuously by only one hydraulic pump.
