Title: Manufacture of vacuum valve
Inventor: HONMA MITSUTAKA
IPC: H01H33/66
Filed: 1994-10-25
Abstract: PURPOSE: To secure productivity and to enhance a withstand voltage characteristic of a vacuum valve without deteriorating an insulation recovery characteristic after current interruption by melting and setting part of the surface portion of each of the pair of contacts in a vacuum, and deoxidizing the surface layer portions of the contacts. CONSTITUTION: The contacts 21a, 21b of a vacuum valve 10 are shaped by cutting and placed in a vacuum having degrees vacuum of 1×10<-3> Pa or less, and then a discharge is caused at an amount of charge of O.01 to 0.5coulomb/ cm<2> per surface area to melt their surface layers. This discharge is effected on a moving cathode spot, and although temperature reaches about 4 deg.C, the life of the discharge is several μ seconds and so only the surface layer portions of the contacts are melted while the insides and the junction of the contacts are not heated. Therefore, a withstand voltage characteristic can be enhanced without deteriorating an insulation recovery characteristic after current interruption by which only gas adsorbed to the surfaces of the contacts can be removed.

Title: Valve timing control device in internal combustion engine
Inventor: WADA KOJI
IPC: F02D13/02
Filed: 1999-09-13
Abstract: PROBLEM TO BE SOLVED: To fix a VVT actuator at most stable position by estimating the driving force of a valve timing variable mechanism (VVT) actuator according to supply oil pressure, and controlling the opening and closing timing of an intake and exhaust valve when the estimated value is below the valve timing variable control limit boundary value. SOLUTION: A variable control limit means learns the driving force (ACT driving force) of a VVT actuator which satisfies a designated response time as a valve timing variable control limit boundary value (VVT control limit boundary value) FL during valve timing variable control. The VVT control limit boundary value FL is updated according to the actual spark-advance amount (actual spark-advance amount) θa to a valve timing variable control spark-advance command, and the updated amount is determined by the time change rate of the actual spark-advance amount θa. When the ACT driving force is remarkably lowered, that is, even in the case of below the VVT control limit boundary value, the control of the valve timing control means is limited so that the VVT actuator is fixed in a most stable position so as to stabilize the operating condition.

Then a mixed coefficient generating section generates coefficients K1, 1-K1, K2, and 1-K2 from the correlation coefficients MAX and MIN and a chrominance component processing means 200 selectively inputs BPF signals passed through a BPF, 1/2-difference signals between the signals V and VH, and 1/2-difference signals between the signals VH and VHH and generates chrominance signals C by mixing various chrominance components together in a prescribed area. In addition, a luminance signal generating means 300 detects luminance signals Y based on the chrominance components C and composite video signals V. Therefore, the naturalness of videos separated by luminance signal/chrominance component separation can be improved.
