Title: Control method for clutch
Inventor: MAKABE MITSURU
IPC: F16D48/06
Filed: 1989-06-29
Abstract: PURPOSE:To smoothly control clutch-on by correcting a prescribed time for which a timer starts at beginning of control of clutch-on mode territory I and an actuator stops after passing the prescribed time to move into control of territory II, at detecting a clutch-on point. CONSTITUTION:When a judging part 42 judges a clutch-on mode at starting, the territory I judging part 45 of a target clutch speed computing part 44 is started to control clutch-on of the territory I through a driving part 50 and a DC motor 8, and a timer 54 is also started. At reaching the timer time set with a setting part 55, the DC motor 8 is stopped to move into control of a judging part 46 of the territory II. Hereat, the timer time is corrected by detecting the clutch-on beginning point with a detecting 56. Thus, even at wear of the clutch facing, clutch-on control can be smoothly performed by quickly transferring from the territory I to the territory II of half clutch.

Filed: 1990-06-27
Abstract: PURPOSE:To generate a reduced picture with fidelity to an original signal by applying reduction processing by a reduction circuit to a picture element series doubling equivalently a sampling frequency by means of an interpolation circuit. CONSTITUTION:A sampling means 11 samples an input analog picture signal to eliminate reflected distortion caused in the reduction by a digital filter 12 and a picture selected in response to a desired reduction rate at a reduction circuit 13 and a variable coefficient are multiplied and the result is stored in a picture memory and then read and a picture reduced by the desired reduction rate is displayed on the screen. An interpolation circuit 14 applies interpolation processing doubling equivalently the sampling frequency in comparison with a time series synthesis series of an output picture element of the sampling means 11. Thus, an accurate and sharp reduced picture is obtained.
