Title: Air fuel ratio control device for internal combustion engine
Inventor: MAKINO HIRONOBU
IPC: F01N3/20
Filed: 1994-12-28
Abstract: PURPOSE: To utilize the oxygen storage effect of three-way catalyst sufficiently according to the operating conditions and the degree of deterioration of the three-way catalyst. CONSTITUTION: The air fuel ratio of exhaust gas is detected by an upstream side O2 sensor 124, and a reverse frequency and amplitude is measured by a control part 13. Also the constants related to the control of air fuel ratio (a skip constant, integral constant, etc.) are changed so that the optimum frequencies and amplitudes determined according to the operating conditions of an internal combustion engine are identical to actually measured values. Then the amount of fuel injected from a fuel injection nozzle 113 is determined using these constants so as to purify exhaust gas by sufficiently utilizing the oxygen storage effect of three-way catalyst 123. In addition, the oxygen storage effect can be utilized more effectively by changing the optimum reverse frequencies and amplitudes according to the degree of deterioration of the three-way catalyst.

Title: Automatic warehouse
Inventor: NAKAJIMA ICHIRO
IPC: B65G1/04
Filed: 1990-11-30
Abstract: PURPOSE:To enhance the accuracy of stopping a stacker crane of an automatic warehouse which includes a plurality of trays installed on a horizontal cross- beam, by sensing the tray position using a reflex plate furnished in a single piece with each tray. CONSTITUTION:The level of an elevating/sinking member 32 is adjusted and set so that photo-electric sensors 38a, 38b mate with a reflex plate 25a of the undermost tray 20. When the member 32 is fixed so that these sensors 38a, 38b mate with reflex plate 25a of tray at N'th stage, a stacker crane 30 is put in traveling from one end to the other. Because the sensors 38a, 38b intersect the reflex plate 25a during this travel, they are turned on and off. The count at this time on a pulse encoder for traveling is determined and stored in memory in correspondence to the position of tray 20. When the other end is reached, the elevating/sinking member 32 is moved so that the sensors 38a, 38b mate with reflex plate one stage over, and is stopped. Then measurement is made in the same fashion while the stacker crane 30 is traveled in opposite direction. This operating cycle is applied to all stages.

IPC: H02J3/36
Filed: 1992-12-09
Abstract: PURPOSE:To make optimum frequency control possible by adjusting the quantities of support power at normality and at emergency by means of a variable limiter. CONSTITUTION:A variable limiter 35 limits the output of a proportional control system 33 by the upper limit value and the lower limit value different in the width of the ripple of frequency, and outputs it as a frequency control command value. This command value is added to the preset power set value, and it is given to a converter controller 21, becoming the DC power command value shown by the quantity of support power lent from other AC system 1B to the AC system 1A where there was the ripple of system frequency. Hereby, the range of the quantity of support power, which is lent between the AC systems 1A and 1B, can be adjusted by the variable limiter 35 so that it may not be the disturbance of the system at normality when the width of the ripple of the system frequency is small, and that it can be permitted to the full capacity of the system facility at emergency when the width of the ripple of the system frequency is large. Hereby, optimum frequency control can be performed.
