摘要:
A separator material effective for decreasing the weight of fuel cells is provided which is lightweight, has good corrosion resistance, and exhibits a minimized increase in electrical contact resistance during use for a long period. Titanium or a titanium alloy is prepared by melting so as to contain not greater than 5 mass % B, thereby forming a titanium-based material in which fine TiB-type boride particles are precipitated and dispersed. The material is then etched in an aqueous acidic solution such that some of the TiB-type boride particles are exposed on the surface through the passive film formed thereon.

The steering control device performs a control of applying an assist torque based on a steering by a driver. Concretely, the steering control device sets a transfer function from an inputted steering angle to a wheel turning angle to a predetermined frequency response. Then, the steering control device determines the assist torque corresponding to a steering amount based on the frequency response, a transfer function of the steering angle in a relational formula between the steering angle, the wheel turning angle and the assist torque, and a transfer function of the assist torque in the relational formula. By executing the steering assist based on the determined assist torque, it becomes possible to control the response of the wheel turning angle to the steering angle with high accuracy.

The present invention provides an automatic priming method by which priming is conducted while keeping, in the automatic priming, an arterial-side chamber in a normal position as in a case of dialysis treatment, and in which forward and backward rotations of a blood pump are employed, and a speed of rotation, in particular, backward rotation is adjusted to be low so that air or the like is reliably prevented from entering a dialyzer. The priming method is characterized by including, in a blood purification circuit in which priming is conducted by supplying physiological saline into a circulation circuit formed by connecting an arterial blood circuit (L1) with a venous blood circuit (L2), (1) an early injection step of filling the venous blood circuit with a priming solution (physiological saline), (2) an overflow step of discharging the priming solution for cleaning the arterial blood circuit, (3) a reverse direction re-circulation step of conducting a treatment in a direction opposite to the overflow step, which may be followed by a forward direction re-circulation step, and (4) a forward direction re-circulation step.

The present invention provides an indoor unit of an air conditioner, which is capable of improving the safety regarding the opening and closing movements of a movable panel. An indoor unit of an air conditioner includes a front grill, a second panel, a driving machine, and a second panel supporting member. The front grill is provided with a first intake port at a front thereof. The second panel is provided such that it covers the first intake port, opens the first intake port by moving away from the first intake port and closes the first intake port by moving close to the first intake port. The driving machine generates a driving force to move the second panel. The second panel supporting member has a gear portion and a plate member. The gear portion transmits the driving force of the driving machine to the second panel. The plate member is provided outside the gear portion, and covers a gap between the second panel and the front grill in a state in which the second panel is open.

A relay apparatus for connecting a radio network and a wire network, includes: a priority control unit configured to control a data sending order to the radio network based on a priority assigned to each data piece; a setting unit configured to set the priority in sending data received from the wire network to the radio network; and a priority assigning unit configured to assign the priority set through the setting unit to the data received from the wire network and to be sent to the radio network.
摘要:
A vehicle tire information obtaining apparatus for obtaining tire information relating to a mounted tire and a non-mounted tire of a vehicle. The apparatus includes: (a) tire state detectors which are provided in the respective tires and each of which detects a state of the corresponding tire; (b) transmitters which are provided in the respective tires and which transmit tire data sets, as the tire information, each containing at least one tire-state data element representative of the detected state of the corresponding tire; (c) a receiver which is provided in a body of the vehicle and which receives the tire data sets transmitted by the transmitters; and (d) a non-mounted-tire information separator which separates the tire data set transmitted from the non-mounted tire, from the tire data set transmitted from the mounted tire.
摘要:
A tire-state obtaining apparatus operable to detect the states of tires of wheels and including (a) wheel-side devices each including a transmitter device (42), and (b) a body-side device including a receiver device operable to receive tire information from the wheel-side devices, wherein the positions of the wheels from which sets of the tire information have been transmitted are determined on the basis of the condition in which the receiver device receives the tire information. The receiver device includes a plurality of antennas oriented to receive the tire information from the respective wheel-side devices, and the wheel corresponding to the antenna having the highest intensity of reception of the tire information can be determined as the wheel from which the tire information has been transmitted, so that the antennas need not be located near the respective wheels, to identify the wheels.
摘要:
A refrigerator has a two-stage compressor and means for switching refrigerant flow between a primary channel and a bypassing channel at downstream of a condenser that is connected with an outlet of the two-stage compressor. The primary channel extends from a first exit of the means for switching, through a first capillary tube and a first evaporator, to a gas-liquid separator, a gas-exit of which is connected with a second evaporator through a second capillary tube. The bypassing channel extends from a second exit of the means for switching, through a bypass capillary, to the gas-liquid separator. When flow of refrigerant in the second evaporator is substantially interrupted and so detected, refrigerant flow is switched to the bypassing channel, by means for controlling.
