Title: Power system simulator
Inventor: KONISHI HIROO
IPC: H02J3/00
Filed: 1987-06-19
Abstract: PURPOSE:To prevent accumulation of phase shift between calculation result of a computer and actual output from a waveform generating circuit, by detecting phase shift of an output waveform of the waveform generating circuit from a referential point and producing a command value for next step terminal voltage based on the detected phase shift. CONSTITUTION:A phase shift detecting circuit 500 for detecting phase lag with reference to a timing signal SYNC based on the timing signal SYNC fed from a sinusoidal wave generating circuit 200 and an output from a terminal voltage detector 102 for generator is provided. Detected signal is taken into a computer 100 and employed for determining amplitude and phase of generator terminal voltage in next step (next timing) and initial value of phase in frequency calcula tion. Since next step values are calculated in the fidelity computer 100 based on a detected phase shift of output from the sinusoidal wave generating circuit 200, system constant can be simulated with high fidelity.

Filed: 1997-06-10
Abstract: PROBLEM TO BE SOLVED: To make close contact force between the top face of a lid body and a valve body storing, eliminate high projection of the valve body from the top face of the lid body or the like, thereby preventing the valve body from being hit with an object easily, and maintain a pressure-reduced and, hermetic state steadily during portage and storage requiring the pressure-reduced and hermetic state. SOLUTION: The food container is provided with a pressure-reducing mechanism 8. The pressure-reducing mechanism 8 comprises an air inlet/outlet hole 6 for maintaining a pressure-reducing hermetic state by closely contacting container main body 1 and a lid body 2, by allowing either the bottom face 1a of the container main body 1 or a top face 2a of the lid body 2 or both to be freely bent and deformed, and by pressing one or both of them, thereby expelling air in the container main body 1. The mechanism 8 further comprises a valve body 7 for opening/closing the air inlet/outlet hole 6. The air inlet/outlet hole 6 is arranged in a valve seat 9, a hemispherical recess formed in the top face 2a of the lid body 2.
