Title: Diaphragm pump
Inventor: MATSUMOTO YOSHIHISA
IPC: F04B43/02
Filed: 1979-05-09
Abstract: PURPOSE: To reduce stating torque of a motor by mounting a spring having urging force corresponding to a half of total sum of discharge pressure load and suction pressre load applied to a diaphragm.  
     CONSTITUTION: A compression spring 11 having in the middle of the reciprocating stroke a force corresponding to a half of total sum of loads which apply discharge pressure (+) and suction pressure (-) of a pump to the effective area of a diaphragm 10 in the opposite directions is urged to oppose said load. When the diaphragm 10 is operated to move to the compression side in a pump pressure chamber 15, it is operated by halved force with the aid of the force of said urged spring 11. On the other hand, when the diaphragm is pulled up, it can be operated with the pullingup force corresponding to the force of said urged spring 11, resulting in the operation of the diaphragm 10 with a uniform drive force for the reciprocation of the diaphragm 10 to reduce the starting torque of a motor.

Abstract: PURPOSE: To construct a port island on a good sea-bed by a method wherein sea water is filled into an inner side of a pontoon and the sea-bed of sand under the pontoon is compressed with a weight of the sea water in the pontoon and a weight of the pontoon itself.  
     CONSTITUTION: Sea bottom ground a is enclosed by a concrete frame b, sludge within the frame is replaced by sand c and a surface of the sand is smoothed into a level. Subsequently, a plurality of pontoons f are floated within the frame and are connected each other with bolts j to make a gigantic pontoon. Guide pillers i are inserted into cylinders h attached to four corners of the pontoon. Next, valves on upper side of the pontoon are opened to pour sea water, then, the gigantic pontoon is sunk along the guide pillers i and is bottomed on the sand c. Therefore, the sand c is compressed in maximum by a weight of the sea water within the pontoon and a weight of the pontoon itself because these are becoming to a sinking weight upon the maximum low tide. After the sand is compressed, flow out of the sand is prevented by concrete plates n and a port island consisting of the pontoon may be completed.

Abstract: PURPOSE: To suppress a vehicle vibration so as to contrive reduction in a vehicle shock when accelerated, by determining a fuel injection correction amount with a time, delayed by a time required for nearly one turn of an engine from the lapse of time after judging a start of acceleration by an acceleration condition detecting means, serving as the reference. CONSTITUTION: At lock up time of an automatic transmission 1 with lock up mechanism, in an acceleration condition detecting means 6, a vehicle is judged for whether it is in an acceleration condition or not by whether or not ratio of an intake air amount to a rotational speed is a prescribed value or more. When judged the acceleration condition, a counter value of measuring a number of times of fuel injection is not leading to a prescribed value, and when during correction control is judged, from a correction table, a fuel injection amount, in accordance with a vibration condition of a resonance frequency detecting means 7 and a number of times of fuel injection, is obtained. Correction timing is unconditionally determined from a resonance frequency.  Since the correction table includes a prescribed delay time (time required for about one turn of engine) in accordance with a counter, in a certain time after judging starting acceleration, a fuel injection amount is not corrected, thereafter to make the fuel injection amount to be a positive next negative value.
