A vehicular drive system accommodated in a housing and including a first input shaft that receives a vehicle drive force generated by a vehicle drive power source, and a differential mechanism operable to distribute the vehicle drive force received from the first input shaft to a first electric motor and a second input shaft. The first and second input shafts are disposed coaxially with a first axis such that the second input shaft is disposed downstream of the first input shaft. The first input shaft is rotatably supported by a first support portion provided on the housing and an axial end portion of the second input shaft, and the second input shaft is rotatably supported by a third support portion and a fourth support portion that are provided on the housing.

A horizontal groove extending horizontally when an alternator bracket is fixed to a cylinder block of a vehicle engine is formed in the alternator bracket. A shank of a bolt inserted through mounting pieces of an alternator is inserted into the horizontal groove from a horizontally lateral direction toward the cylinder block to support the bolt on a lower surface of the horizontal groove. After insertion, the bolt is restrained from moving toward an opening of the horizontal groove. Since the insertion of the bolt into the horizontal groove is facilitated, and the weight of the alternator is borne by the lower surface of the horizontal groove, a burden on a fixing portion is reduced, and it becomes easy to position the alternator and hold it when it is fixed. Thus, the accessory can be mounted on the cylinder block with satisfactory work efficiency and with support accuracy kept high.

A hybrid vehicle driving apparatus includes: a first rotor shaft of a first electric motor, the first electric motor being disposed on a first axis; a power distribution mechanism that includes a planetary gear device and is disposed on the first axis; an output gear shaft that serves as an output member of the power distribution mechanism and is disposed on the first axis; a counter shaft disposed on a second axis; a second rotor shaft of a second electric motor disposed on a third axis; a power transmission shaft disposed on the third axis; a differential gear disposed on a fourth axis; and a casing that includes a plurality of case members. The output gear shaft, the power transmission shaft, the counter shaft, the differential gear, the first rotor shaft, and the second rotor shaft are rotatably supported by a common case member that is one of the plurality of case members.

A hybrid driving unit in which a first electric motor (20), a second electric motor (23), a transmission (22) and a power splitting planetary gear (21) are disposed in order from the front side (the side of an internal combustion engine) on an axis within a casing member (14). Since the first electric motor (20) and the second electric motor (23) are disposed adjacently to each other, partial cases for storing these first and second electric motors (20) and (23) may be combined, thus facilitating the accommodation for producing the unit in series.

The invention relates to an angle adjusting device which comprises a base and an angle operating piece. An arc-shaped guide rail is arranged on the base, and the angle operating piece is slidably arranged on the arc-shaped guide rail under driving of a driving mechanism. The driving mechanism comprises a linear guide rod arranged on the base, a driving piece slidably arranged on the linear guide rod, and a power device for driving the driving piece to move in the length direction of the linear guide rod. The driving mechanism further comprises a driving connecting piece which is rotatably connected with the driving piece and movably connected with the angle operating piece along a linear guiding device fixedly arranged on the angle operating piece. The angle adjusting device decomposes thecomplex linkage relation between the driving piece, making simple linear movement, inside the driving mechanism and the angle operating piece making arc-shaped movement into two types of movement components which are easier to control, and accordingly, the angle precision and control precision are improved.

The invention relates to a construction method for a basement arc-shaped outer wall based on a stereo-type bracket single side formwork. The construction method for the basement arc-shaped outer wallbased on the stereo-type bracket single side formwork is characterized in that anchor backing plates are preinstalled in a basement base plate, horizontal sliding grooves are formed in the lower portions of the anchor backing plates; a bracket base plate is arranged on the upper surface of the basement base plate, an arc-shaped formwork guide slot is formed in the position, corresponding to an outer wall internal mold, of the bracket base plate, a stand column is arranged on the upper surface of the basement base plate, a column top beam is arranged at the top of the stand column; a first hanging beam is connected with a second hanging beam through a hanging beam poisoning frame; a steel bar cage gripper is arranged at a cantilever end of the first hanging beam; a connecting protruding falcon and a connecting groove are formed in the joint position of an assembly type outer mold, a waterproof layer and a vertical-directional supporting rod are arranged on the outside of the assembly type outer mold; a protective layer control strip is arranged between the assembly type outer mold and an outer wall inner mold and a wall body steel bar cage; and an assembly type outer mold limiting groove and a supporting rod limiting groove are formed in the foundation of the wall bottom in a pre-installation mode. The construction method for the basement arc-shaped outer wall based on the stereo-type bracket unilateral mode branch not only can improve the construction efficiency of the arc-shaped outer wall and the formwork bracing quality, but also can reduce the difficulties of lifting and positioning of the wall body steel cage, and further can improve the use ratio of materials.

The invention provides a radial support mechanism of a primary mirror of a large aperture telescope for eliminating the temperature stress, which consists of a radial support base, a lever bracket, clump weights, a lever, a lower pair slider bar, rolling bearings and an indium steel sleeve. The indium steel sleeve is sleeved on the radial support base which is located in the middle of the indium steel sleeve. Silica gel is dotted at a gap fit position between the radial support base and indium steel sleeve so that the indium steel sleeve is fixed on the radial support base. The lever is connected to the radial support base via two mounting screws. The pivot end of the lever is connected to the lever bracket by two rolling bearings through the lower pair slider bar. The clump weights are screwed in the lower end part of the lever in threaded connection. Two bearing cover plates cover the bearing holes on the lever bracket. When the radial support mechanism of the primary mirror works, the radial support mechanism is connected to and fixed on the primary mirror base by means of two mounting screws via the lever bracket, and the radial support base extends to the radial support holesof the primary mirror to be mounted.

A chucking pulley clamps and chucks a recording medium in coaction with a disk table. The chucking pulley has a rotary slide knob and is rotatably supported on a support arm. The support arm has first and second lifting / lowering pins. A holder is mounted on the support arm for pressing the chucking pulley toward the disk table while in contact with an end of the rotary slide knob when the recording medium is in rotation. A spring is resiliently held against the first lifting / lowering pins. Moving members move the chucking pulley toward and away from the disk table. The moving members have retainers for retaining the first lifting / lowering pins in an acting position when the recording medium is chucked. The first lifting / lowering pins retained in the acting position deform the spring to bias the support arm and the holder toward the disk table.
