Abstract: A lubrication structure of a gear change mechanism includes an actuation valve, a valve body, a detent member, and an elastic contact member. The actuation valve is to set the gear change mechanism to a selected shift position status. The valve body is to house the actuation valve. The detent member is disposed in a vicinity of the valve body and is movable by an operation of the actuation valve. The valve body includes a supply port to supply a hydraulic oil to the detent member. The actuation valve is to communicate the supply port and a drain oil passage in the valve body with each other in a case where a predetermined shift position is selected. The elastic contact member is engaged to one of a plurality of groove portions provided in the detent member.

Abstract: An automatic transmission includes an input member, a planetary gear set, a plurality of engagement mechanisms, an output member, a shift position detecting unit, an input rotational speed detecting unit, a control unit, and a switching mechanism. When a shift position is changed from a forward drive range to a reverse drive range, the control unit performs a reverse preparation mode in which a rotational speed of an element to be fixed by the switching mechanism is lower than or equal to a predetermined speed by setting an engagement mechanism in one of a connection mode and a fixed mode. Upon performing the reverse preparation mode, the control unit engages the engagement mechanism that connects the element fixed by the switching mechanism to the input member and, thereafter, engages the engagement mechanism that makes the rotational speed of the input member lower than or equal to the predetermined speed.

The elastic wave filter includes a dummy electrode disposed in at least one of the input-side IDT electrode portion and the output-side IDT electrode portion to suppress reflection of a diffracted elastic wave by the busbar and to suppress spurious response at an end portion in a frequency pass-band. The dummy electrode has a width dimension and a pitch that are determined such that none of a period shorter than a shortest period of the electrode fingers and a period longer than a longest period of the electrode fingers is satisfied.

Abstract: The present invention provides a new high-strength and Si—Cr containing hot rolled steel plate provided with higher strength as well as excellent workability and a method for manufacturing the steel plate. The high-strength steel plate can be obtained by controlling the particle size of prior austenite to be 10 ?m or less, and properly selecting the coiling temperature. The steel plate obtained includes a retained austenite phase in a volume fraction of 5% to 20%; a martensite phase in a volume fraction equal to or less than 10%; and a bainite phase in the remaining volume fraction. The particle size of the retained austenite particle is 1 ?m or less and the retained austenite particles are dispersed uniformly.
