Abstract: PURPOSE:To speed up the response speed of frequency tuning and to miniaturize a tuning oscillator by constituting a means for impressing a DC magnetic field on a ferrimagnetic thin film resonant element by means of a permanent magnet giving a solid magnetic field and a coil giving a variable magnetic field. CONSTITUTION:The DC magnetic field is impressed on the ferrimagnetic thin film resonant element (YIG thin film oscillator, for example) 2 connected to an FET1 for oscillation by the permanent magnet 4c and the main coil 4b. When a channel is selected by a channel selection circuit 6 here, the oscillation output of the FET1 which has been frequency-divided and a reference frequency are phase-compared in a PLL circuit 5, and a control current corresponding to the result is fed back to the main coil 4b. Since a part of the magnetic field required for frequency tuning can be dealt with the permanent magnet 4c, and the winding of the coil 4b can be reduced for the number at that time, the inductance of the coil 4b can be reduced. Thus, the response speed of frequency tuning can be speeded up and the oscillator can be miniaturized.

Title: Measuring device and method for interference between intake/exhaust valve and piston
Inventor: SHIN TATSUHYON
IPC: F01L1/02
Filed: 1997-10-15
Abstract: PROBLEM TO BE SOLVED: To improve the durability and reliability of an engine by utilizing the measured interference information between an intake/exhaust valve and a piston, and applying specific reinforcement, adjustment, and correction. SOLUTION: A change of about ΔL is measured between the valve lift locus at the time of a design and the actual rotation of a cam shaft caused by various self-load factors during the rotation process through the tension, rigidity, or power transfer of a power transmission means. When the gaps between a valve and a piston in the top dead center(TDC) process of the piston are compared between the actual locus of the valve generated by the actual rotation change of the camshaft and the valve locus of a design value, the gap L2 between the valve and piston measured from the actual locus of the valve is larger than the gap of the design value. The increment can be measured as the deformation of the camshaft or the abnormality of the tension and rigidity of the power transmission means.  A design suppressing the occurrence of interference between the valve and piston can be made by adjusting the opening/closing timing of the intake/exhaust valve in consideration of the deformation of the camshaft and the tension and rigidity of the power transmission means.
