摘要:
A piston shoe for fluid pressure pump motors of the piston type is substantially disc-shaped and includes a concave portion provided upon one end face thereof for seating the convex portion of a piston rod associated with the piston and cylinder assemblies of the pump motor, while the other end face thereof is substantially flat for contacting the sliding surface of a swash plate. A holder or retainer is also provided in association with the shoe for retaining the piston rod within the concave seat, such retainer being secured to the shoe by biasing means, or alternatively by being pressed or crimped thereon.

A hydrostatic transmission includes a hydraulically controlled speed differential means drivingly connected with an output shaft for transmitting the rotation torque of an input shaft to the output shaft and including a hydraulic element functionable as a reaction element therefor, a hydraulic positive displacement pump-motor drivingly connected with the input shaft for controlling the hydraulic element in accordance with the displacement ratio thereof, and a line circuit to provide hydraulic communication between the hydraulic element and the pump-motor. In the hydrostatic transmission, a drive power train selector gear unit is disposed between the input shaft and the speed differential means to selectively complete the forward and reverse drive power trains inbetween the input shaft and the output shaft by way of the speed differential means.

摘要:
By a QTL analysis and so forth using 4-HPPD inhibitor-susceptible rice and 4-HPPD inhibitor-resistant rice, a hypothetical gene (HIS1 gene) of an iron/ascorbate-dependent oxidoreductase gene located on a short arm of chromosome 2 of rice has been identified as a 4-HPPD inhibitor-resistance gene. Further, it has also been revealed that a homologous gene (HSL1 gene) of the HIS1 gene is located on chromosome 6 of rice. Furthermore, it has been found out that utilizations of these genes make it possible to efficiently produce a plant having increased resistance or susceptibility to a 4-HPPD inhibitor and to efficiently determine whether a plant has resistance or susceptibility to a 4-HPPD inhibitor.

Provided is a position information providing system which can reduce a time required for acquiring position information. An indoor transmitter is adapted to provide position information by using a second positioning signal compatible with a first positioning signal which is a spread spectrum signal from each of a plurality of satellites. The indoor transmitter includes an EEPROM which stores therein position data for identifying an installation location thereof, an FPGA operable to generate a second positioning signal including the position data as a spread spectrum signal, and a transmitting section operable to transmit the spread spectrum signal. The second positioning signal is generated to repeat the same content in a cycle shorter than that of the first positioning signal.

The disclosed image forming apparatus includes a rotatable image holding body configured to hold an electrostatic latent image on a surface of the image holding body, a developing device including a forward rotation developing roller rotatable in a same rotational direction as that of the rotatable image holding body and a reverse rotation developing roller rotatable in a reverse rotational direction to that of the rotatable image holding body, which supply a two-component developer to the surface of the image holding body to form a toner image corresponding to the electrostatic latent image, and a control unit configured to control rotation of the image holding body, the forward rotation developing roller, and the reverse rotation developing roller to supply the two-component developer. The control unit controls the rotation of the image holding body to start after a predetermined time period from starting the rotation of the forward rotation developing roller and the reverse rotation developing roller.
