Title: Perpetual motion apparatus with pendulum-like weights
Inventor: OOKUMA HIDEHIKO
IPC: F03G7/10
Filed: 1981-10-03
Abstract: PURPOSE:To produce rotation of a turning member, by causing unbalance on the opposite sides of the vertical line passing through the center of the turning member through  employment of such an arrangement that pendulum-like weights disposed around the  circumference of the turning member are directed in the same direction at any position  of the circumference of the turning member. CONSTITUTION:A weight 1 in the form of a pendulum is fixed to a shaft 3 together  with a sprocket 3, and two such weights 1 are disposed around the circumference of a  turning member 4 in a freely rotatable manner. The turning member 4 is fixed to an  output shaft 5 and supported by a main body 6 in a freely rotatable manner. A sprocket 7 mounted on the main body 6 has a gear ratio of 1 to the sprocket 3, and a chain  8 is passed around the two sprockets 7 and 3. In the state (a) shown in the drawing,  the weights 1 are directed downward and kept stationary since they are located symmetrically on the opposite sides of a vertical line Z-Z (along which gravity is acted) and balanced with each other. However, in the state (b), the turning member 4 is  caused to turn in a direction Y since the distance l of the center of gravity of one  weight from the line Z-Z is smaller than that l' of the other weight and their balance  is lost resultantly. Similarly, in the state (c), the member 4 is caused to turn in the  direction Y.

Two required points of time during the compressed stroke of the internal combustion engine are detected by a crank angle sensor 10. The air-fuel ratio of a cylinder is measure by a computer 11 based on the respective detection signals, and displayed by a means 12 if necessary. The compressed stroke of the engine is made to follow a polytropic process. The polytropic process means the expansion or compression of gas at the time when PV<n> value is constant, where P,V mean the pressure and volume of gas, and (n) is the polytropic exponent. By using the polytropic exponent (n) as the intermediate medium information, the air-fuel ratio inside the cylinder is measured from the compressed pressure inside the cylinder at the respective points of time.

Filed: 1982-09-11
Abstract: PURPOSE:To realize high speed operation and further curtail the minimum delay time of circuit by using an electrostatic induction transistor formed utilizing a buried layer as an oversaturation preventing element. CONSTITUTION:An N<+> type buried layer 12 is formed with a pattern containing a part 12a being missed, an electrostatic induction transistor(TR) Q3 using the missing part 12 as a channel is formed, and the p type region 20, N<+> buried layer 12 and P type substrate 10 are respectively operated as the source, gate and drain of transistor Q3. In an LSI, oversaturation of TR Q1 can be prevented by the clamping effect of the TR Q3 and therefore holes flow as the majority carrier to the drain from the source of TR Q3. Accordingly, a base current and voltage of TR Q1 is limited and a collector voltage is not lowered and clamped to a constant value. Injection of minority carrier to the N type collector region 14 from the P type base region 20 is limited, minority carrier accumulation effect is lowered and thereby high speed switching of TR Q1 can be realized.
