PROBLEM TO BE SOLVED: To provide a speed change control device for a vehicular continuously variable transmission appropriately reflecting acceleration demand of a driver while inhibiting a sense of incongruity from being given to the driver by appropriately establishing target rotation speed when acceleration is demanded by the driver. SOLUTION: Since a quick speed change time TQ which is a quick speed change section is established based on deviation e between actual input shaft rotation speed N IN and acceleration target rotation speed NINLINE pre-established by a target rotation speed establishing means 96 establishing quick speed change transition target rotation speed NINLINEPQ increased in a stepped manner as the quick speed change section when an accelerator operation judgment means 88 judges that the driver demands acceleration, the speed change control device can establish target rotation speed not to make the drive feel speed change shock easily and to inhibit deterioration of speed change response when the driver demands acceleration, and can appropriately reflect acceleration demands of the driver while suppressing sense of incongruity given to the driver.

PROBLEM TO BE SOLVED: To provide a technology capable of shortening a time required for preparing walking figure data. SOLUTION: The computer system 30 is provided with a storage means 46a of tip toe positional data, a means 40, which prepares body trunk positional data on the assumption that "both arms of a robot are fixed to a body", a storage means 46c' of finger tip positional data, a storage part 126 of a body trunk position correcting amount, which stores the relation between the difference of the finger tip position and a correcting amount of a body trunk position, and a device 128 for correcting the body trunk positional data. The correcting device 128 calculates the difference between the finger tip position on the assumption and the finger tip position of the finger tip positional data, specifies the body trunk position correcting amount from the difference and the storage contents of the storage part 126 of the body trunk position correcting amount, and corrects the body trunk positional data on the basis of the specified body trunk position correcting amount.

PROBLEM TO BE SOLVED: To improve a walking speed of a biped walking robot by designating a trunk position vector P and a trunk twist vector Q. SOLUTION: This robot walks while twisting a trunk in a range of an angle formed by a line for connecting left-right feet and the walking direction by preparing the trunk twist vector Q for walking command data. For example, the robot walks while maintaining the proportional relationship between the angle formed by the line for connecting the left-right feet and the walking direction and an angle formed by a line for connecting the left and right of the trunk and the walking direction. The robot walks at a high speed by securing a step larger than a case of a robot for walking without twisting the trunk. COPYRIGHT: (C)2004,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a control device for a vehicular torque distribution clutch improving fuel economy of a vehicle and enhancing durability of the vehicular torque distribution clutch. SOLUTION: A torque distribution clutch control means 120 controls transmission torque tr (=t ref ) of an electromagnetic clutch 30 based on a map value M tindf (V) of a traveling resistance relation quantity, and the fuel economy of the vehicle is improved and durability of electromagnetic clutch is enhanced. That is, since the torque distribution clutch control means 120 reduces the transmission torque tr (=t ref ) toward zero as input torque t in of the electromagnetic clutch 30 reduces, while large torque is distributed through the electromagnetic clutch 30 to enhance acceleration performance when the input torque t in is larger than the map value M tindf (V), engagement load in the electromagnetic clutch is suppressed to further improve fuel economy and enhance the durability of the torque distribution clutch when the input torque t in is smaller than the map value M tindf (V).

Abstract:
PROBLEM TO BE SOLVED: To provide a polymer electrolyte film having proton conductivity even at a low moisture content. SOLUTION: A compound expressed in formula [1] is structured from a polymer material retained by an organic polymer resin. R 1 is a substituted or non-substituted aryl group, Rf 1 and Rf 2 denote perfluoroalkyl groups independently of each other. That is, having an ultra-strong acid group makes a high degree of dissociation of the proton, so that a high proton conductivity is realized without in intermediary of water. When adopted for a fuel cell, there is no need of humidifying gas, so that a humidifier in the gas can be omitted or simplified which leads to lower cost of the fuel cell. COPYRIGHT: (C)2003,JPO

PROBLEM TO BE SOLVED: To detect the pressure highly accurately by a contact pressure sensor for detecting the bearing pressure. SOLUTION: A pressure receiving block 3 for transmitting the force from a counter side member to a sensing part 2 is provided, and platform parts 321, 322, 323, 324 for placing the pressure receiving block 3 are provided protrusively on the formation positions of pressure detection gages 421, 422, 423, 424 of the sensing part 2. The pressure receiving block 3 has a shape having a larger abutting area on the counter side member than a plane area of the platform parts 321-324, to thereby concentrate the force from counter side member onto the gage 421-424 formation positions, and to improve detection sensitivity.
