摘要:
Measurement is made of a time of lapse from the time at which the hydraulic pressure of the hydraulic engaging element on engaging side to be engaged at the time of speed changing has increased to a predetermined pressure. Even if an input and output speed ratio of the transmission does not fall within a predetermined range, i.e., a range between YG(N+1)L and YG(N+1)H, which serves as a basis for judging whether the speed changing has been completed or not, a processing of speed change completion is performed when the above-described value TMSTB-TM has reached a predetermined value YTMUP4, to boost the ON pressure to the line pressure.

A composite resin material exhibiting excellent physical properties, which is formed by adding semi-rigid or rigid polyurethane resin waste to a thermoplastic reactive resin, a nonreactive resin, a polymer alloy or the like. A first kind of the composite resin material is composed of a crosslinking polyurethane resin and a reactive resin, a nonreactive resin or a polymer alloy, which is formed by kneading the crosslinking polyurethane resin and the reactive resin, the nonreactive resin or the polymer alloy at a predetermined temperature or more. A second kind of the composite resin material is composed of a hydrolysis product of crosslinking polyurethane resin and a solid filler, which are mixed with a nonreactive resin and a polymer alloy by kneading. A third kind of the composite resin material is formed by kneading a moisture-absorbing crosslinking polyurethane resin, a reactive resin and one of a reactive resin, a nonreactive resin and a polymer alloy composed of a resilient rubber material and a thermoplastic resin at a temperature of not less than the hydrolysis temperature of the crosslinking polyurethane resin and not less than the melting point of the one of the nonreactive resin and the polymer alloy.

Both shocks and time lag at the time of gear-in are reduced. For that purpose, the hydraulic pressure of a hydraulic engaging element to be engaged at the time of gear-in (in-gear pressure) QING is increased relatively rapidly at the beginning of gear-in. The speed of increase of QING is lowered after the input and output speed ratio "Gratio" of a transmission has exceeded a predetermined value YINGS which works as a basis for discriminating the start of engagement of the hydraulic engaging element.

An A/F sensor generates a current signal corresponding to an air-fuel ratio in response to a voltage applied by a bias control circuit. After a sensor current is received as a voltage signal via a voltage follower, it is outputted to an A/D converter having a predetermined input voltage range, 0 to 5V. A sensor current detection circuit has a plurality of current detection resistors. In order to variably set the resistance value by the sensor current detection circuit, a switch circuit is switched in accordance with the sensor current depending on whether the A/F value to be detected is in the zone near the stoichiometric ratio or in other air-fuel ratio zones.

A disk player including a 1 DIN size housing, a plurality of disk holders stacked in the housing, a selecting member for moving the disk holders to provide a space below a selected disk holder, and a driving member for moving into the space and aligning with a center of a disk supported on the selected disk holder. Each disk holder has a recessed portion for receiving a disk therein such that the disks are horizontal, and projections which are slidably connected to the housing such that the disk holders are only movable in a vertical direction within the housing. The selecting member is slidable in the horizontal direction and includes a plurality of elongated guide grooves, each elongated guide groove receiving the projection extending from one of the disk holders such that movement of the selecting member relative to the housing causes movement of a selected disk holder in the first direction. The driving member is mounted on a drive base which pivots to position the driving member under the disk.
