Title: Exhaust control device of two-cycle engine
Inventor: ASANO KIYOMORI
IPC: F02B25/20
Filed: 1990-07-23
Abstract: PURPOSE:To minimize a hammering noise of a piston at most by forming on an upper side of an exhaust passage a communication passage which is opened on a portion upper than an exhaust port for communication of the cylinder and a seat part of an exhaust valve. CONSTITUTION:An exhaust control valve 11 for changing an exhaust timing is rotatably fitted to an exhaust passage 9. A part of a cylinder 2 upper than an exhaust port 6 is communicated with the exhaust passage 9 through a communication port 12. The earlier exhaust timing is obtained by opening the communication port 12 than that at the wholly opening time of the valve, a starting of compression is delayed by the forwarded time. When the communication port 12 is opened under a low engine speed area, a secondary compression ratio at that time is lowered. An explosion pressure is lowered and a stable combustion condition is obtained.

Title: Optical fiber gyro
Inventor: YAMAMOTO TSURASHI
IPC: G01C19/72
Filed: 1995-07-28
Abstract: PROBLEM TO BE SOLVED: To allow a small size and a low cost and improve straightness and precision by producing a reference phase difference and a lamp phase difference in a signal showing the intensity of interference light with a phase controller. SOLUTION: A phase controller 8' to control the phase of light propagating an optical fiber loop 3 produces a reference phase difference Δβ and a lamp phase difference σ in an intensity signal I for interference light by using a delta serrodyne waveform signal. The phase of the intensity signal I for the interference light is x=Δθ+σ+Δβ, where Δθ is a sagnac phase difference. The reference phase difference Δβ varies to contant values ΔβA and ΔβB with the same absolute value and difference signs for every times TA and TB. The ramp phase difference σ is controlled to be Δθ+σ=0 and so the sagnac phase difference Δθ is equal to the lamp phase difference σ at a stable point on the control loop.  The phase x of the intensity I of the interference light does not contain the sagnac phase difference Δθ, that is X=Δβ. With the reference phase difference Δβ set to be a certain value, a desired moving point can be selectively located.
