摘要:
A maximum flow calculating unit calculates a maximum amount of hydraulic fluid that can flow into or out of an input-side hydraulic cylinder when a shift control command signal is set to a reference DUTY value, based on an estimated valve pressure difference calculated by an estimated pressure difference calculating unit, and a post-guard target sheave position setting unit performs a guard process for restricting the amount of change of the sheave position, using a guard value calculated by a guard value calculating unit based on the maximum flow amount, so as to set a post-guard target sheave position. Since the thus set target sheave position does not undergo excessive large changes nor excessively small changes during shifting, a target value for shifting is set so that a feedforward controlled variable determined based on the amount of change of the target sheave position becomes an appropriate value.

The present invention pertains to a catalyst comprising 7–20 wt. % of a Group VIB metal component, calculated as trioxide on the weight of the catalyst, and 0.5 to 6 wt. % of a Group VIII metal component, calculated as oxide on the weight of the catalyst, on a porous inorganic carrier. The catalyst has a specific surface area of 100–180 m2/g, a total pore volume of at least 0.55 ml/g, at least 50% of the total pore volume in pores with a diameter of at least 20 nm (200 Å), 10–30% of the total pore volume in pores with a diameter of at least 200 nm (2000 Å), and 0–1% of the total pore volume in pores with a diameter above 1000 nm (10000 Å). The catalyst is particularly suitable for the hydroprocessing of heavy hydrocarbon feeds of which at least 50 wt. % boils above 538° C. (1000° F.). It is especially advantageous for the hydroprocessing of feedstocks of which at least 80 wt. % boils above 538° C. (1000° F.).

An apparatus for analyzing control data for finding a cause of a trouble produced in a device controlled with a plurality of controlled variables. The apparatus includes sensors sensitive to a condition of the device for producing signals indicative of parameters reflective of the sensed condition. The parameter indicative signals are fed to a control circuit which calculates a valve corresponding to a setting of each of the controlled variables from a desired relationship. The calculated values are stored in time sequence along with the corresponding values of the parameter indicative signals. The stored values are transferred from the first memory to a second memory upon occurrence of a command signal indicating a trouble produced in the device. The transfer values are analyzed to find a cause of the trouble.
摘要:
In a control device for a vehicle on which is mounted a continuously variable transmission capable of mechanically locking a primary pulley at the time of a maximum gear ratio (maximum Low), an idle rotational speed is not always set high to increase a hydraulic pressure at the time of stopping the vehicle. Instead, at the time of stopping the vehicle, when the gear ratio of the continuously variable transmission is the maximum gear ratio, normal idle rotational speed control is performed, and only when the gear ratio is not the maximum gear ratio, idle-up control is performed so that the idle rotational speed is set high, thereby the hydraulic pressure is set high. Thus, by restricting conditions in which the hydraulic pressure is set high by the idle-up control, it is possible to improve fuel efficiency while suppressing generation of a belt slip.

A driving power source rotational speed control device is provided in a vehicle outputs power of a rotary driving power source via a continuously variable transmission as motive power, that changes the rotational speed of the rotary driving power source in association with changes in the vehicle speed when acceleration is requested. The control device includes: acceleration/deceleration state determination means determines whether the vehicle is accelerating or decelerating when acceleration is requested; and rotary driving power source rotational speed change setting means sets the change gradient of the rotary driving power source rotational speed to establish the association of the rotary driving power source rotational speed with changes in the vehicle speed when acceleration is requested. The rotary driving power source rotational speed change setting means suppresses reductions in the rotary driving power source rotational speed when the acceleration/deceleration state determination means determines that the vehicle is decelerating.

When a mobile telephone requests a web server for HTML page data containing a link, the server generates an identifier and appends the identifier to the link. An HTML page containing the link with the appended identifier is generated by the server and is transmitted to the telephone. If content of the link is requested by the telephone, then the content is transmitted to the telephone and an access log entry is recorded at the server. The log entry includes the identifier and the content request. If identifiers are found to be in common, the number of times this content was accessed is construed to be a single time. Even if a single item of content is divided into multiple portions and requested multiple times, the number of multiple times is treated as being a single time. The number of times access was performed can be calculated comparatively accurately.
摘要:
In a controller for a belt-type continuously variable transmission including a hydraulic actuator that changes a groove width of a primary pulley, a hydraulic actuator that changes a groove width of a secondary pulley, and a belt clamping pressure control solenoid that controls the hydraulic pressure supplied to the hydraulic actuator of the secondary pulley, a mechanism calculates a transmission ratio between the primary pulley and the secondary pulley and determines whether or not there is belt slippage based on that calculated transmission ratio, and a mechanism determines normalcy of the belt clamping pressure control solenoid. The input torque when belt slippage has actually occurred, i.e., when a failure has been determined, is used as a condition when performing the normalcy determination. By setting such a condition, it is possible for a normalcy determination threshold value (input torque value α) used for the normalcy determination to be a small value, and thus it is possible to suppress erroneous normalcy determination.
