When initial control ends, an ECU executes a program that includes the steps of: calculating a return control progression degree; calculating a target amount of change in turbine speed; calculating a feedback gain; calculating a target turbine speed; calculating a deviation between the target turbine speed and turbine speed NT; determining a hydraulic pressure command value; outputting the hydraulic pressure command; and when the turbine speed is synchronized with a first gear synchronization speed, outputting the maximum hydraulic pressure command.

An ECU executes a program that outputs a shift command when a determination has been made to perform a power-on downshift (i.e., YES in S100); controls the hydraulic pressure supplied to a friction engagement element to perform the power-on downshift; allows the correction of the hydraulic pressure supplied to the friction engagement element during the power-on downshift when the difference between a target input torque and an estimated input torque is equal to or less than a threshold value ΔTT (1) (i.e., YES in S130); and correcting the hydraulic pressure supplied to the friction engagement element during the power-on downshift.

A control apparatus for a vehicle equipped with an automatic transmission having an apply element that is applied when the vehicle takes off from a standstill, which executes a neutral control which releases the apply element when the automatic transmission is in a forward-drive range and the vehicle is stopped with a predetermined condition being satisfied, includes a controller that detects a target idle speed of an engine and determines whether the neutral control can be executed based on the target idle speed.
摘要:
In a control apparatus for an automatic transmission, a return control is executed to engage a clutch that has had its engagement pressure lowered and to disengage a brake so as to resume the state of the automatic transmission from the neutral state under a neutral control to the one where the forward speed is established. As the time for the neutral control becomes longer, the decrease in the torque of an output shaft of the automatic transmission becomes gentler. Accordingly an initial value of a control command value for the clutch pressure is decreased with the increase in the neutral control time such that the engagement of the clutch becomes gentler.

The invention provides a method for recovering metal beryllium from waste beryllium that has become radioactive in the reaction with neutrons, by converting the radioactive beryllium to halogenated beryllium with a halogen gas such as chlorine, bromine or iodine, and subsequently submitting the halogenated beryllium to thermal decomposition. In this way, the invention allows effective recovery of metal beryllium from waste, radioactive beryllium, thereby reducing production of radioactive wastes and ensuring an economical use of natural resources.

Mo adsorbent for .sup.99 Mo-.sup.99m Tc generators has a skeleton structure having mainly repeating units represented by the general formula; ##STR1## wherein X is a halogen atom or alkoxide group having one to six carbon atoms, 10% or more of X is halogen, R is an alkylene, polymethylene, or carbon chain having unsaturated bond, repeating unit (D) is bonded to any one of repeating units (A), (B), and (C), the branch structure is controlled by the content of repeating units (A), (B), and (C), the adsorbent is insoluble in water and adsorbs selectively only Mo from an aqueous solution containing Mo, and elutes .sup.99m Tc generated from a radioactive isotope .sup.99 Mo. This Mo adsorbent uses .sup.99 Mo obtained from natural Mo by (n, .gamma.) method, therefore, a generator having the same size as conventional .sup.99m Tc generators is realized.

A fluid pressure control device is equipped with a valve body which has an input port connected to a hydraulic fluid source, an output port which is connected to a pressure chamber of a clutch of an automatic transmission, and a discharge port. It further includes a solenoid valve which is incorporated in the valve body and has a valve spool designed to selectively connect the output port to the input port or the discharge port. A discharge passage extends from the discharge port of the valve body, the discharge passage having a discharge port which is positioned at a higher level than the liquid level of the oil pan of the automatic transmission. Finally, a reed valve acts to close the discharge port of the discharge passage to maintain fluid at the aforementioned higher level, and allows the discharge of the hydraulic fluid only through the discharge port.

An organic silazane polymer is prepared by passing a silazane compound in por form through a hollow tube heated at 400.degree. to 700.degree. C. for activation and thermally polymerizing the silazane compound in a liquid phase. Inorganic fibers can be prepared from the organic silazane polymer by melt spinning, infusibilizing, and sintering. An apparatus for preparing an organic silazane polymer is also provided, comprising a heated reactor vessel for evaporating and thermally polymerizing a silazane compound, a heated hollow tube in flow communication with said reactor vessel for receiving the silazane compound vapor and heating it at 400.degree. to 700.degree. C. for activation, and a conduit, with a condenser for condensing the vapor, for feeding the condensed silazane compound back to the reactor.

A nut anti-slipping member is provided, which has a nut insertion groove and covers bottom end portions of one-side opening end of a nut insertion hole. A nut is inserted in the nut insertion hole with the nut deviated from the nut anti-slipping member. In case when the nut is of a square-pole-shape type with rectangular section, the entire nut can pass upper parts of the anti-slipping member when the nut is inserted in the nut insertion hole in a horizontally longitudinal position, and a bottom part of the nut can pass the nut insertion groove when the nut is inserted in the nut insertion hole in a vertically longitudinal position.
