Title: Microwave composing circuit device
Inventor: TANAKA TOSHINORI
IPC: H01P5/02
Filed: 1987-07-03
Abstract: PURPOSE:To enable impedance matching between an input and an output microwave line, to put input signals together with excellent electric separation, and to reduce the size of a device by cascading a common gate FET and a common drain FET. CONSTITUTION:A 1st input microwave line 23 which has characteristic impedance Z01 is connected to a 1st source electrode of the common gate FET 21 and a 2nd input microwave line 24 with characteristic impedance Z02 is connected to a 2nd source electrode of the FET 21. Further, the 1st and 2nd drain electrodes of the FET 21 are connected in common to the gate electrode of a common drain FET 22 with mutual conductance gm3. Then the FETs 21 and 22 are cascaded to eliminate the opposition coefficient between an input terminal and an output terminal, and consequently the impedance matching between the input and output lines is attained and an opposite-directional transmission coefficient becomes zero, so the input and output lines are separated electrically. Consequently, the input signals can be put together with excellent electric separation between the input and output microwave lines without using any isolator.

Title: Shift controlling device for continuously variable transmission
Inventor: OCHIAI TATSUO
IPC: B60W10/109
Filed: 1997-06-24
Abstract: PROBLEM TO BE SOLVED: To certainly complete shift to minimum transmission gear ratio of continuously variable transmission without causing racing of an engine during stopping, by setting a target transmission gear ratio to be larger than normal minimum transmission gear ratio during rapid speed reduction where vehicle's deceleration exceeds a set deceleration which is larger with increasing of car speed. SOLUTION: During driving of a vehicle, a controller 13 inputs output signals from a G sensor 15, a throttle aperture sensor 16, a primary pulley rotational sensor 17, a secondary pulley rotational sensor 18, and a car speed sensor 19, and derives real transmission gear ratio. Shift region, that is shift region during rapid speed reduction, normal shift region, or transmission gear ratio fixing region, is judged based on a map from car speed and vehicle acceleration/deceleration. When it is judged to be shift region during rapid speed reduction, a target transmission gear ratio is set to be transmission gear ratio larger than the normal minimum transmission gear region (more speed reduction side which does not exist mechanically).  Transmission gear ratio deviation between the large target transmission gear ratio and real transmission gear ratio is calculated, and a step motor 14 performs down-shift to minimum transmission gear ratio.
