Title: Switched capacitor amplifier circuit
Inventor: YOSHIZAWA HIROKAZU
IPC: H03F3/70
Filed: 1997-10-24
Abstract: PROBLEM TO BE SOLVED: To correctly obtain output without variation in the potential at a virtual ground terminal even in the case of abrupt variation in input voltage by connecting two input capacitors in series. SOLUTION: So that abrupt variation of an input signal exerts a little influence on the output of a sampling phase, the capacity on the input side of the switched capacitor amplifier circuit is formed by connecting two capacitors 4 and 5 in series and one of the two input capacitors 4 and 5 is allowed to operate as one buffer. So that leak current is prevented from being accumulated in the parasitic capacity that the two capacitors 4 and 5 have, a switch 1.2 is connected to the connection point between the two input capacitors to form a DC path. Two-input, two-output complete differential type constitution using a two-input, two-output operational amplifier 1 is employed for the switched capacitor amplifier circuit to reduce in-phase feedthrough and noise through the in-phase removing operation that the operational amplifier has.

Title: Hydraulic control of continuously variable automatic transmission for vehicle
Inventor: YOKOYAMA SHOJI
IPC: F16H59/70
Filed: 1989-11-11
Abstract: PURPOSE:To prevent an endless belt from slipping by making the control pressure for the hydraulic servo of a following side pulley higher than ordinary control pressure based on engine load and reduction gear ratio at the time of manual gear shifting toward increasing transmission gear ratio. CONSTITUTION:When a manual shift valve 65 is set to L range to operate engine brake, the larger one of the throttle pressure from a throttle valve 40 or the pressure from a low modulator valve 10 is set in an oil passage 2, but at this time the pressure in the oil passage becomes higher than ordinary throttle pressure corresponding to engine load force because the low modulator pressure is higher than the throttle pressure. Then the pressure in the oil passage 2 works on the spool of a pressure governing valve 30, and the setting point of the line pressure in the oil passage 1 to a hydraulic servo 570 in a following pulley is changed so that it may be higher than ordinary line pressure. It is thus possible to prevent the endless belt from slipping.
