Each pivot shaft of a drive chassis has hooks to allow the drive chassis to be held by a main chassis. Preferably, each bearing portion of the main chassis corresponding to each of the pivot shafts has an engagement groove, while the main chassis has stoppers for preventing positional slippage of the pivot shafts. Thus, in case a force is applied to the drive chassis in a direction perpendicular to an optical disc insertion direction, the hooks of the each shaft of the drive chassis are stopped by an inner wall of the engagement groove and the stopper, respectively, of the main chassis. Thereby, the drive chassis is prevented from falling off the main chassis.

A method and device for manufacturing UOE steel pipes, wherein, when an opening width of the U-can obtained by U-ing press is larger than the die-diameter in an O-press of later step, while said opening is narrowed from the front end by the closing rolls disposed before said O-press and/or at least at the entrance portion of the O-press to be smaller than the die-diameter of said O-press, the U-can is simultaneously conveyed into the O-press, and then, after charging into the O-press, undergoes O-ing press to yield an O-can. The device is preferably configured to have the closing rolls disposed in a roll stand and consisted of multiple pairs, to have a mechanism to prevent the U-can from moving upward during narrowing the opening width, and to have the function of conveying the U-can. Thus, UOE steel pipes for high-strength application corresponding to X80 grade can be efficiently manufactured.

The grill shutter is disposed between the front grill and the air intake duct. The grill shutter is capable of opening or closing shutter members and regulating positions of the shutter members when being opened. When a maximum supplied flow rate of air provided by the wind during running is greater than a flow rate of air required for the hydrogen fuel battery, the required flow rate of air is established only by opening/closing control of the shutter members through a grill shutter opening instruction. If this is not the case, the grill shutter members are opened fully through the grill shutter opening instruction to maximize the volume of the wind during running taken in from the front grille. Additionally, a shortfall in the required flow rate of air for the hydrogen fuel battery is compensated for by actuating the blower through a blower speed instruction.

An optical pick-up device having cheap and simple structure capable of precisely positioning members assembled upon an actuator base makes use of respective flush screw members for a magnet holder and for a printed-circuit board eccentrically positioned between an actuator base and a magnet holder, together with between the printed-circuit board and the support member. The flush screw member is inserted through the holder hole, firmly secured into the screw hole, and thereby prevents the pick-up device from being loosened, because of being provided with a predetermined eccentric distance between center axles of the screw hole and the holder hole. Likewise, a triangle-shape opening of the printed-circuit board is adapted to receive the board flush screw, so that a slant tapered surface of a board flush head of the board flush screw acts as an eccentrically fastener for fixture and positioning of the support member and the printed-circuit board.

Various arrangements are disclosed wherein biomass processing services are provided to a producer of an agricultural product. One such arrangement may include the producer paying a fee or offering biomass related products to a buyer in exchange for receiving the biomass processing services. At least a portion of the fee for providing the biomass processing services may be paid by delivery of a quantity and/or quality of agricultural products, biomass byproducts, or biomass derivative products. In certain embodiments, arrangements between the producer and the buyer may also involve establishing vendor credit accounts or providing other financing programs to the producer.

In order to achieve an object of making an optical pick-up have a cheap and simple structure capable of precisely positioning members assembled upon an actuator base 1, the optical pick-up device make a use of respective flush screw members 19, 20 for a magnet holder 11 and for a printed-circuit board 15 eccentrically positioned between an actuator base 1 and a magnet holder 11, together with between the printed-circuit board 15 and the support member 2. The flush screw member 19 serves to be inserted through the holder hole 11a, to be firmly secured into the screw hole 1a, and to thereby prevent the pick-up device from being loosened, because of being provided with a predetermined eccentric distance t1 between a center of axle O1 of the screw hole 1a and a center of axle O2 of the holder hole 11a. Likewise, a triangle-shape opening 15b′-1 of the printed-circuit board 15 is adapted to receive the board flush screw 20, so that a slant tapered surface 20a of a board flush head 20-1 of the board flush screw 20 acts as an eccentrically fastener for fixture and positioning of the support member 2 and the printed-circuit board 15.
