RIDING WORK MACHINE

PROBLEM TO BE SOLVED: To increase the weight of a forward part of a vehicle body, and to change the weight of each part of the vehicle body as necessary by forming a vehicle body frame in a forward-down inclined condition, providing a working machine fitting part on a rear part of the vehicle body frame, and sealing a liquid inside the vehicle body frame. SOLUTION: When a liquid, mainly water is poured from a pouring port 80b, water flows into a sub frame, and also flows into a main frame through a connection arm 66. Air in a vehicle body frame forward of a drain valve 81b is exhausted from an air vent 82b while air in the vehicle body frame rearward of the drain valve 81b is exhausted from an air vent 82a or the pouring port 80b. Thus, water is spread to a frame tip, and water of a specified quantity can surely be stored in the vehicle body frame. Fine regulation of the weight balance after water is once stored or water discharge in the vehicle body frame after the agricultural work are ...

OPTICAL PICKUP DEVICE

PROBLEM TO BE SOLVED: To provide an optical pickup device which is capable of reducing the movement amount of a coupling lens suitable as a slim type thanks to small size and low cost, and capable of recording and reproducing information on/from an optical disk having multilayered information recording surfaces. SOLUTION: Focus jump for selecting one of the plurality of information recording surfaces is performed by moving a group of positive lenses L2 of the coupling lens CL in an optical axis direction. A spherical aberration which increases with a change of environmental temperature or a wavelength variation of a light source is corrected by driving a liquid crystal element LCD.

OPTICAL PICKUP DEVICE AND RECORDING DEVICE, AND REPRODUCING DEVICE

PROBLEM TO BE SOLVED: To provide a condensing optical system and an optical pickup device capable of effectively correcting fluctuation in spherical aberration by a simple configuration which is generated on each optical surface of the optical pickup device due to a change in the wavelength of a light source, a change in temperature/humidity, a tolerance of a transparent substrate thickness of an optical information recording medium or the like. SOLUTION: The fluctuation in the spherical aberration generated on each optical surface in the condensing optical system, particularly on the optical surface of an objective lens is correctable by making at least one of two lens elements composing a coupling lens shiftable along the direction of an optical axis. An appropriate spot can be formed always on the information recording surface of the optical information recording medium, since the fluctuation in the spherical aberration can be corrected in real time which is seriously generated on the ...
