Herein disclosed is a shift fork lubricating system for use in a transmission of the type in which shift forks (4.sub.1, 4.sub.3) have their bearing portions (10.sub.1, 10.sub.3) slidably fitted and supported on a shift fork shaft (2) and their forked pawl portions (6.sub.1, 6.sub.3) formed at their leading ends for engagement with circumferential grooves (8.sub.1, 8.sub.2) of shift gears (7.sub.1, 7.sub.3) so that the shift gears (7.sub.1, 7.sub.3) are shifted by the sliding controls of the shift forks (4.sub.1, 4.sub.3). The bearing portions (10.sub.1, 10.sub.3) of the shift forks (4.sub.1, 4.sub.3) have their inner circumferences formed at their center areas with annular oil grooves (16.sub.1, 16.sub.3), respectively, which are axially elongated and always in communication with oil ports (14.sub.1, 14.sub.3) opened to the outer circumference of the shift fork shaft (2). The shift forks (4.sub.1, 4.sub. 3) have their inner circumferences formed at both the sides of the annular oil grooves (16.sub.1, 16.sub.3) with pairs of sliding faces (17.sub.1, 17.sub.3 ; 18.sub.1, 18.sub.3) which have a substantially equal axial length and which are made slidable on the shift fork shaft (2). The shift forks (4.sub.1, 4.sub.3) are further formed therein with oil passages (15.sub.1, 15.sub.3) which are opened into the forked pawl portions (6.sub.1, 6.sub.3) thereof and which communicate with the annular oil grooves (16.sub.1, 16.sub.3).
摘要:
A rotor cover is disposed at one end surface of a rotor which has a ring-shaped locking ridge on the end surface thereof. The locking ridge has an outer peripheral surface fitted in a locking groove in the rotor cover. A holder is held against an inner peripheral surface of the locking ridge. With this arrangement, the diameter of the rotor is kept constant at all times, and so is the gap between the rotor and the housing, thus preventing scuffing of the rotor and the housing.

A tape pack ejecting mechanism wherein a tape pack is loaded and unloaded into and from a pack receiving structure pivotally connected at one end portion thereof to a chassis so as to allow pivotal movement thereof, locking of the pack receiving structure in a tilted position is released by loading of the tape pack, bringing the tape pack into a horizontal playback position, and the pack receiving structure is again tilted through rotation of an engaging member upon depressing of an eject lever to eject the tape pack, which mechanism is characterized by a guide provided at one side portion of the pack receiving structure for guiding the loading and unloading of the tape pack; and eject operating member with a tension spring attached thereto which is slidably provided on the guide; said eject operating member having a hanging portion engageable with a rear end of the tape pack and a projection engageable with a lock portion formed on the engaging member; said tension spring being biased to urge when the tape pack is loaded into a playback mode; said engaging member being reset by the rebounding force of the urged spring to eject the tape pack through the operation of the engaging member rotated upon eject operation by the eject lever.
摘要:
An object of the present invention is to provide a turbine external compartment, a frame for a turbine external compartment, and a method of constructing a frame for a turbine external compartment that can improve a flow of steam inside of the compartment and can enhance the rigidity of the compartment using a simple structure. A turbine external compartment according to the present invention is placed in a frame having a steel-plate reinforced concrete structure obtained by filling a space between a plurality of steel plates with concrete. The turbine external compartment includes a lower half part having a side plate part or an end plate part made of the steel plates that constitute the frame.

The present invention provides a bearing material that is excellent in durability and is capable of maintaining wear resistance over a long period of time. The bearing material of the present invention is a high wear-resistance bearing material 10 for being used under a humid environment comprising: a base body 12 made of a polymer material having a methylene group; and a polymer layer 30 covering a bearing surface 16 of the substrate 12, the polymer layer 30 comprising polymer chains which have a phosphorylcholine group and are grafted from the bearing surface 16, wherein a phosphoric index of the sliding surface 16 which is calculated by dividing a peak intensity of phosphate group in an infrared spectrum measured on the sliding surface by a peak intensity of the methylene group therein is not less than 0.28.

A picture signal processor includes: a frame-rate conversion section performing a frame-rate-increasing conversion, which brings an over-double frame rate, on each of a plurality of time-series picture streams each including a plurality of unit pictures, and providing frame-rate-converted picture streams to a display section which displays pictures through performing time-divisional switching of picture streams from one to another in order; and a shutter control section controlling a shutter eyeglass device to perform an open/close operation in synchronization with a display switching timing between the frame-rate-converted picture streams in the display section.
摘要:
A steam turbine has an outer casing that is divided into an upper casing and a lower casing (a lower block) on a horizontal plane through which a rotor passes. The upper casing is divided into a middle block having a through hole and an upper block having a top panel, that is, into a portion including at least a part of the through hole through which the rotor penetrates. With this configuration, machining of a bellows fitting unit provided in an end-plate cone portion can be performed in existing facilities such as a factory, in a state that the lower block and the middle block are assembled without assembling the upper block.
