Title: Robust controller
Inventor: OISHI KIYOSHI
IPC: G05B13/04
Filed: 1987-08-18
Abstract: PURPOSE:To suppress an influence of parameter fluctuation and disturbance and to perform the control of high response speed by providing a compensating means where the deviation between the controlled variable of a controlled system model and that of an actual controlled system is inputted to a high frequency band differential compensating element to give a manipulated variable. CONSTITUTION:The manipulated variable obtained from a control part 2 is applied to a first adding means 3 together with a compensation manipulated variable, and the manipulated variable from the means 3 is given to a controlled system model 4, and the deviation between the controlled variable obtained from the model 4 and that obtained from a controlled system is detected by a deviation detecting means 5 and is applied to a high frequency band differential compensating element 6 to obtain the compensation manipulated variable. This compensation manipulated variable is not only given to the first adding means 3 but also amplified by an amplifying part 7 and is given to a second adding means 8, and the output of the first adding means 3 is added and the result is given to the controlled system. Thus, the output fluctuation is reduced to cancel the output deviation even in case of the existence of parameter fluctuation and disturbance in the controlled system 1.

Filed: 1981-12-21
Abstract: PURPOSE:To prevent the oil droplet generated during a partial cylinder operation for a long time from being tarred by forcibly releasing the partial cylinder operation to perform a full cylinder operation when the partial cylinder operation is continued for a predetermined time or longer. CONSTITUTION:The air flow to resting cylinders 10d-10f is cut off and also rest side injectors 26d-29f are made off by closing an intake cutoff valve 24 by means of the first diaphragm device 26 introduced with a negative pressure  during a light load operation of said engine. In addition, a discharge cutoff valve  40 is fully opened by means of the second diaphragm device 42 to feed back the  discharge gas to the resting cylinders 10d-10f. In this case, if a partial cylinder operation is started by a control device 64, the operation time is counted and when the operation time exceeds a predetermined time, e.g., two hours, a warning is given to the driver, then a control is made to switch to the full cylinder operation forcibly and to return to the partial cylinder operation again.

Title: Floating-up sliding door induced by electromagnetism
Inventor: ENGETSU HIKARI
IPC: E05F1/00
Filed: 1993-06-28
Abstract: PURPOSE:To obtain a sliding door which can be opened quietly by using a metal-made threshold and installing magnets whose magnetic poles may be directed at the bottom of the sliding door. CONSTITUTION:Magnets 2 whose magnetic poles are directed at a metal-made threshold 3 are laid out on the bottom of a sliding door 1. When the door 1 is pulled and moved, the magnetic poles of the magnets 2 laid out on the bottom of the door 1 act on the threshold 3, thereby generating an induced current and inducing magnetic poles. Since the magnetic poles of the door 1 and the induced magnetic poles on the threshold side 3 are identical, there are produced repulsive forces so that the door may be floated up. When the bottom of the door 1 and the top of the threshold 3 are V-shaped respectively, if the door is deviated to either the left side or the right side, the repulsive forces are so stronger that the door may be pulled back to the central part since the distance between the door and the adjacent threshold 3 is near, which prevents the threshold 3 from coming off. This construction eliminates the need for a rotary unit and to open and close the door quietly by floating up the door 1.

Title: Device for removal of harmful substance from exhaust gas
Inventor: TSUJIMURA MANABU
IPC: B01D53/70
Filed: 1988-08-24
Abstract: PURPOSE:To remove harmful substance from exhaust gases by installing an addition- reaction tank, wherein gases, which are able to be liquefied or sublimated under atmospheric temperature and pressure, a selectively condensed or sublimated, on the upstream side of an exhaust-gas reaction tank to prevent blocking of the exhaust-gas reaction tank. CONSTITUTION:When a group of gases A, which are easily liquefied or sublimated under atmospheric temperature and pressure, and a group of gases B in gaseous state, being mixed together, flow into an addition-reaction tank 12, a majority of the group of gases A is liquefied or sublimated since the temperature of the tank 12 is located slightly lower than that of an exhaust-gas reaction tank 5 situated downstream, while the group of gases B remain in gaseous state, whereby the group of gases B which haven't been condensed or sublimated and a part of the group A flow into the tank 5, while, since the temperature in the tank 5 is higher than that of the tank 12, the gases having flowed into the tank 5 are subjected to an adsorption reaction in gaseous state, without being liquefied or sublimated. Consequently, blocking of the interior of the tank 5 is avoided and harmful substances are removed from the exhaust gases without fail.
