Abstract: A control apparatus for a synchromesh automatic transmission (3) for automatically changing over a plurality of speed gear stages from one to another in an internal combustion engine (1), which apparatus is capable of suppressing occurrence of rapid deceleration of the engine, engine blowup or like problems even when the accelerator pedal is manipulated during a period in which the throttle valve is being closed. The control apparatus includes an electromagnetic clutch (2), an accelerator pedal position sensor (13), an engine rotation speed sensor (15), and a control unit (4) arranged such that upon decision of start of upshift operation, a closing speed of an electronically controlled throttle valve (11) is arithmetically determined by the control unit (4) on the basis of a data map prepared in advance with opening degree of the throttle valve (11) being controlled in response to a command value issued by the control unit (4).

Abstract: A control apparatus for a synchromesh type automatic transmission system of a motor vehicle capable of suppressing speed-stage downshift operation which may occur successively upon application of sudden braking as well as occurrence of a gear squeaking phenomenon and shock due to speed change brought about by the downshift operation. The control apparatus includes a shift/select actuator of a multi-stage speed change gear unit (3), a brake switch an accelerator pedal position sensor, an output rotation speed sensor, and a speed stage control means for controlling the shift/select actuator on the basis of detection signals outputted from the sensors. When it is decided that the brake switch is in a closed state and that the deceleration determined arithmetically on the basis of the vehicle speed is not greater than a predetermined value the multi-stage speed change gear unit is shifted to a neutral position and thereafter the decision as to the speed change is suspended.

Abstract: Gears in a synchronous engagement type transmission are shifted through positional control by a shift/select actuator to thereby automate speed change. A controlling apparatus for a synchronous engagement type transmission includes a shift/select actuator for switching a plurality of gear stages of a synchronous engagement type automatic transmission, a shift position sensor for detecting a shift position of the automatic transmission, a select position sensor for detecting a select position of the automatic transmission, an engine rpm sensor for detecting an rpm of an engine, and a control unit for controlling the shift/select actuator on the basis of the sensor outputs of these sensors. In the case where the shift position and the select position are not in a neutral position when a key switch is turned on, the shift/select actuator is controlled to return the shift position and the select position back to the neutral position.

Abstract: To minimize a delay time of the start of the control of a solenoid valve for changing gear ratios of a transmission, the need for a speed change is judged and when the speed change is needed, a control cycle of the solenoid valve is made longer than the control cycle in the steady state.

Abstract: A control unit 11b which consists of a microcomputer compensates the detected intake manifold pressure Pb with an atmospheric pressure, obtains a first estimated position of the throttle when the amount of by-pass air is null and a second estimated position of the throttle when the mount of by-pass air is the maximum from the intake manifold pressure compensated with the atmospheric pressure and the detected revolution speed Ne, obtains the ratio of the amount of by-pass air currently under control to the maximum controllable amount of by-pass air, estimates the position of the throttle from the ratio and the first and second estimated positions of the throttle, and collates the estimated position of the throttle after compensation and the detected vehicle speed V.sub.s with the speed change map to shift the gear of the automatic transmission 3.

Abstract: In the fuel cut state during deceleration, an actual vehicle speed Vs is compared with a target vehicle speed Vso when the direct coupling state is changed into a semi-coupling state, or otherwise an actual engine rotational speed Ne is compared with a return engine rotational speed Neo at the return from fuel cut. Then, if Vs.ltoreq.Vso or Ne.ltoreq.Neo+K (K is a positive predetermined value), the clutch is changed from the direct coupling state into the semi-coupling state. Thus, shock due to torque change at the time of return from fuel cut can be reduced, and during the coast down, the fuel cut state can be maintained until the low rotational speed is attained. Both improvement of fuel economy and efficient use of engine brake can be attained. Engine stall can be prevented at the time of abrupt braking.

Abstract: A method and apparatus for alternately capping both glass and semirigid plastic bottles. A mechanically actuated cap applying head is mounted for vertically reciprocating movement so as to apply a downwardly directed capping force on the bottle. A hand manipulated dual position stop mechanism limits the downwardly directed capping force in one mode to accommodate semirigid containers and in the other mode removes the downward force restraint for capping glass bottles.
