摘要： An upshift is effected by releasing an engaged first friction element and engaging a released second friction element. The first fiction element operates on a fluid pressure applied thereto through a first passage and the second friction element operates on a fluid pressure applied thereto through a second passage. An accumulator is provided in the first fluid passage. The accumulator has a back pressure port through which a back pressure is applied thereto by the function of a control valve having a first port connected to the back pressure port, a second port connected to a source of back pressure and a third port connected to a drain. The control valve operates, between a first position connecting the first port to second port and a second position connecting the first port to the third port, on first and second working signal pressures applied thereto. The first working signal pressure is the fluid pressure applied through the second passage to the second friction element and the second working signal pressure corresponds to the engine load. The control valve changes from the first position to the second position when a pressure difference between the first and second working signal pressures reaches a predetermined value. The application of the first working signal pressure to the control valve is inhibited for a predetermined time after an upshift is commanded in the automatic transmission or until the existing gear ratio reaches the gear ratio provided when the upshift is commanded in the automatic transmission.

摘要： A downshift control device for an automatic transmission is provided in which the transmission is shifted down by releasing an oil pressure from a first engaging element that has been engaged while applying an oil pressure to a second engaging element that has been released. This downshift control device includes an applied pressure control actuator for controlling a pressure to be applied to the second engaging element, by supplying a pressurized oil to a back pressure chamber of an accumulator provided in an oil path to the second engaging element, and removing the pressurized oil from the back pressure chamber. This control actuator receives a first command to supply the pressurized oil to the back pressure chamber from the time when a downshift command is generated to a predetermined time or the time when a detected gear ratio starts being changed, and then receives a second command to remove the pressurized oil from the back pressure chamber until the detected gear ratio reaches a predetermined gear ratio just before completion of shifting. The control actuator then receives a third command to supply the pressurized oil to the back pressure chamber after the detected gear ratio reaches the predetermined gear ratio.

摘要： In a noncontact information carrier reader, a receiving unit receives a response wave transmitted from a noncontact information carrier. The response wave is generated by modulating the carrier wave based on a response signal. An amplifying unit amplifies carrier wave components contained in the received response wave based on a first gain, and amplifies response signal components contained in the received response wave based on a second gain. The second gain is higher than the first gain. A synchronized-detection demodulator demodulates the response signal components contained in the response wave by mixing the transmitted carrier wave and the response wave amplified by the amplifying unit.

摘要： A select-shock control system of an automotive automatic transmission is shown. The transmission has an engaging element which becomes engaged due to application of hydraulic pressure thereto when it is needed to shift the transmission from a neutral condition to a drive condition. The control system comprises a select determination section which determines whether or not the transmission should be actually shifted from the neutral condition to the drive condition; an accelerator pedal depression sensing section which senses depression of an accelerator pedal; and a control section which, when the accelerator pedal depression sensing section senses the depression of the accelerator pedal just after determination of the drive condition from the neutral condition by the select determination section, raises obliquely the hydraulic pressure from a first lower level which was kept before depression of the accelerator pedal to a second higher level corresponding to the degree by which the accelerator pedal has just been depressed.

摘要： A downshift control device for an automatic transmission is provided in which the transmission is shifted down by releasing an oil pressure from a first engaging element that has been engaged while applying an oil pressure to a second engaging element that has been released. This downshift control device determines whether a downshift command is generated to shift down the transmission while an accelerator pedal is being depressed, and detects a gear ratio that changes during the pedal-depressed downshift control. First control actuator controls the back pressure of a first accumulator provided in an oil path leading to the first engaging element, and second control actuator controls back pressure of a second accumulator provided in an oil path leading to the second engaging element. The present control device outputs to the first control actuator a command to increase the back pressure in a later period of shifting that starts when the detected gear ratio reaches a first predetermined gear ratio, and a command to reduce the back pressure in a terminal period of shifting that follows the later period of shifting. The control device also outputs to the second control actuator a command to reduce the back pressure until when the detected gear ratio reaches a second predetermined gear ratio that is larger than the first predetermined gear ratio and is obtained just before completion of shifting, and a command to increase the back pressure after a point of time when the detected gear ratio reaches the second predetermined gear ratio.
