The transmission 10 is constructed so that, in the first transmission portion 36, the rotation of the input shaft 16 is outputted to the second transmission portion 38 via the first intermediate output path M1 and the second intermediate output path M2 accelerated and rotated with respect to the first intermediate output path M1, and, in the second transmission portion 38, the first rotary element RE1 (S2 and S3) is selectively connected to the first driven gear CG1B via the first clutch C1 and is selectively connected to the second driven gear CG2B via the third clutch C3, the second rotary element RE2 (CA1 and CA2) are selectively connected to the first driven gear CG1B via the second clutch C2 and are selectively connected to the transmission case 12 operating as a non-rotating member via the first brake B1, the third rotary element RE3 (R1, R2 and CA3) is connected to the output gear 28 operating as an output rotating member, the fourth rotary element RE4 (S1) is selectively connected to the transmission case 12 via the second brake B2, and the fifth rotary element RE5 (R3) is selectively connected to the second driven gear CG2B via the fourth clutch C4. A forward multistage transmission can be obtained by engagement operations of the friction engagement devices.

In a hydraulic servo for a clutch, a cancel plate is disposed on a second clutch drum that undergoes the same rotation as a second clutch drum provided with a cylinder portion, in such a fashion that the cancel plate is restricted from moving to a side opposite from a return spring in an axial direction. The first clutch drum is disposed, as a separate member, on the second clutch drum. A step portion of the second clutch drum prevents the first clutch drum from moving to a side opposite from the cancel plate. Due to the spring force of the return spring, the oil pressure in the cancel oil chamber and the oil pressure in the operating oil chamber, the force that presses the first clutch drum to the step portion is always greater than the force that presses the first clutch drum to the cancel plate side.

At a first forward speed, the oil passage in a relay valve is switched to control the torque capacity of a lock-up clutch using a linear solenoid valve that controls the engagement pressure of a clutch that is engaged at each of fifth to eighth forward speeds. At each of second to eighth forward speeds, the oil passage in another relay valve is switched to control the torque capacity of the lock-up clutch using a linear solenoid valve that controls the engagement pressure of a brake that is engaged at the first forward speed.

An apparatus for controlling a lock-up clutch between pump and turbine impellers in a fluid-filled power transmitting device of a motor vehicle, such that a slip control device controls the actual slip speed of the lock-up clutch so as to coincide with a transient target slip speed, the apparatus including a device for calculating a final target slip speed of the lock-up clutch which assures a maximum fuel economy of the vehicle during a steady-state running, a device for setting, as an initial value of the transient target slip speed, a difference between the speeds of the pump and turbine impellers immediately before an operation of the slip control device is initiated, and a device for reducing the transient target slip speed toward the final target slip speed at a rate which decreases as the transient target slip speed approaches the final target slip speed.

A twin-clutch-type transmission, which has a general input shaft, a first clutch connected with a first clutch output shaft, a second clutch connected with a second clutch output shaft, a sub shaft, and a general output shaft disposed parallel to the first clutch output shaft and the second clutch output shaft, is improved to effectively use the space around the sub shaft. A first gear connected to the first clutch output shaft and a second gear connected to the sub shaft associatingly interlock the sub shaft and the first clutch output shaft while being meshed to each other. A fifth gear and a sixth gear disposed on the general output shaft are respectively meshed with the third gear and the fourth gear which are connected to the second clutch output shaft and selectively connected to the general output shaft with a first synchronizing device disposed on the general output shaft, and interlock the second clutch output shaft and the general output shaft in association with the third gear and the fourth gear. A seventh gear meshed with the fifth gear and a eighth gear meshed with the fourth gear disposed on the sub shaft interlock the sub shaft and the general output shaft by selectively connecting the seventh gear and the eighth gear themselves to the sub shaft by the second synchronizing device so as to complete the first forward speed gearing in addition to completing the reverse gearing.

An information processing system includes a first information processing device and a second information processing device. The first information processing device stores a first object group and an additional access control policies. The second information processing device stores access control policies applied to each of second objects. The additional access control policies indicate a changed object group for the each first object. The changed object group is a group of second objects whose access control policy is same as that of the first object. When the second information device obtains an operation request for the first object, the second information device accesses the additional access control policy and determines the changed object group. The second information system judges whether or not the operation request is feasible for the changed object group based on the access control policy, and determines whether or not the target first object is processed.

A variable directional antenna by means of a microstrip antenna and reactance change. The variable directional antenna has a structure to reduce sidelobes occurring when an element interval is reduced, and is structured in a three-element plane, having a feeding element and non-feeding elements provided at both sides of the feeding element. Each of the non-feeding elements provided at both sides of the feeding element has two split non-feeding elements two-divided into sizes of 1:2 in the lateral direction. The split non-feeding element divided into the size 1 is provided closer to the feeding element, and a reactance variable part is connected with the split non-feeding element divided into the size of 2. Alternatively, each of the non-feeding elements provided at both sides of the feeding element has two split non-feeding elements two-divided into sizes of 2:1 in the lateral direction. The split non-feeding element divided into the size 2 is provided closer to the feeding element, and the reactance variable part is connected either with the split non-feeding element divided into the size of 2 or the split non-feeding element divided into the size 1.

In a wireless communication apparatus in a time division duplex system, a transmission signal generation unit generates a transmission signal. A power amplifying device amplifies the generated transmission signal. A control signal generation device generates a drain voltage control signal for control of the drain voltage of the power amplifying device, and a gate voltage control signal for control of the gate voltage of the power amplifying device. The switch unit switches off the drain power supply of the power amplifying device during reception in the time division duplex system according to the drain voltage control signal. In addition, the power amplifying device sets a higher gate voltage during reception in the time division duplex system higher than during transmission according to the gate voltage control signal.
