A flexible container excellent in durability and stability for storage and conveyance and capable to prevent the content in the flexible container from scattering. The flexible container is so constructed that a frame for fixedly supporting a storing bag is provided around the storing bag, so that the storing portion is accommodated in the frame; that the cylindrical injecting portion provided at the top of the storing portion and the cylindrical discharging portion provided at the bottom of the storing portion are extended to a given length from the frame to open to outside; that a folded portion is integrally formed around the outside of the storing bag at a portion thereof near a root portion of the cylindrical discharging portion of the storing bag placed in the frame; that a flange having a pair of ring-like fixing portions to fixedly hold the folded portion in sandwich relation therebetween and a cylindrical portion projecting from an inner periphery of one of the fixing portions is mounted to the folded portion, so that the cylindrical discharging portion is surrounded within the frame by the folded portion and the flange, to form an accommodating portion for accommodating therein the cylindrical discharging portion as folded; and that a lid is detachably provided at an opening of the cylindrical portion at its projecting side.

A roller supporting device which comprises a pair of supporting arms, a supporting shaft attached between the pair of supporting arms in a non-rotatable manner, and a roller having an inner hole in the central part thereof, the roller being disposed between the pair of supporting arms and being supported in a rotatable manner by the supporting shaft inserted through the inner hole, the roller being arranged to rotate along with the relative movement with a mating member by making the roller contact with the mating member, wherein a cut out portion, which extends in the axial direction on the outer circumferential surface of the supporting shaft, is formed at an appropriate portion except the portion on which the inner circumferential surface of the inner hole of the roller is pressed due to the load applied to the roller from the mating member, thereby defining an oil passage which extends in the axial direction between the supporting shaft and the inner circumferential surface of the inner hole of the roller.

The powered ratchet wrench 10 is constructed of several components. A throttle lever 20 controls the air flow to a rotary air motor 30. The rotary output of the motor is transmitted to the hammer assembly 40 of an impact clutch mechanism. A spring 50 biases an anvil shaft 60 into association with the hammer assembly 40. The anvil can be directly driven by the motor through the hammer assembly or can be driven intermittently by a series of rotational impacts from the hammer assembly. The rotation of the anvil shaft causes the reversible ratchet mechanism 70 to rotate in the desired direction, thus tightening or removing a threaded fastener. Only a small reaction force is transmitted by the tool to the operator once the fastener is tightened.

New type porous cordierite ceramics having a new characteristic interconnecting open cellular structure and a hollow microspherical cordierite glass powder with a shell devoid of any pores or provided with a few or an abundance of open pores which is used as a starting material for the porous cordierite ceramics. The porous cordierite ceramics are produced by subjecting a starting solution containing an alkyl silicate, an aluminum salt and an magnesium salt optionally with other compounds in an organic or aqueous organic solvent to spray thermal decomposition to prepare the hollow microspherical cordierite glass powder, and then processing the cordierite glass powder to a shaped body after or before an optional heat treatment and firing the shaped body at a temperature below the melting point of cordierite. The porous cordierite ceramics are useful as a carrier for gas chromatography or various chemical reactions.

An apparatus for detecting a mutual positional relationship of a semiconductor wafer and mask comprises first and second diffraction gratings formed on the wafer and mask and located parallel to each other; a laser source for radiating a coherent light vertically toward the first and second diffraction gratings; a drive mechanism for periodically varying a relative distance between the first and second diffraction gratings; a pair of photosensors for receiving a first interference beam resulting from those +n-order diffracted beams included in said diffracted beams and a second interference beam resulting from those -n-order diffracted beams included in said diffracted beams; and a differential amplifier calculating the difference between the intensities of the first and second interference lights thereby detecting a mutual positional displacement between the first and second diffraction grating.

A method and optical component prevent external light reflection and increase light extraction efficiency. In one example embodiment, an optical component is provided on a light extraction side of a light-emitting panel. After a shielding film shaped like a lattice or a mesh is formed on a transparent substrate, a resist film is formed, the resist film is irradiated with ultraviolet light UV from the back side of the substrate by using the shielding film as a mask, and development is carried out, so that an optical functional element is formed. The planar shape of the undersurface of the optical functional element is the same as the planar shape of the lattice or the mesh of the shielding film, and a positioning error between the optical functional element and the shielding film becomes extremely small.

A packaging pouch for packaging an absorbent article has a front, back and side faces. The side faces are folded between the front and back faces. The packaging pouch is rectangular in use. A sealing portion expanding in a transverse direction around the upper end of the packaging pouch, a side face portion that forms the side face of the package, and a top portion that forms the top face of the package by positioning between the sealing portion and the side face portion are formed. Moreover, perforations are formed in the top portion along a reference line extending in the transverse direction from one side edge of the packaging pouch to the other side edge of the packaging pouch. Handle members extending in the transverse direction from around one to the other side edge and are attached to the front back faces in the top portion below the perforations.

Provided is a method of brake fluid disposal which is characterized in that glycol-based brake fluid is recovered from vehicles, and the recovered glycol-based brake fluid is added to a grinding step of a cement material production facility. Furthermore, a method of brake fluid disposal is characterized in that the recovered glycol-based brake fluid is mixed with diethylene glycol. With these methods, it is possible to reduce troublesome works and effectively utilize the resources in cement material production facilities.
