Abstract:
A pattern forming method includes forming a coating film containing a hydrophilic first homopolymer having a first bonding group and a hydrophobic second homopolymer having a second bonding group capable of bonding with the first bonding group, forming a bond between the first and second bonding group to produce a block copolymer of the first and second homopolymners, and heating the coating film to microphase-separating the copolymer into a hydrophilic domain and a hydrophobic domain. The hydrophilic and hydrophobic domains are arranged alternately. The bond is broken, then selectively dissolving-removing either domain by a solvent to provide a polymer pattern of a remainder domain.
Abstract:
An air bag system having an air bag module 20 including an inflator 22 and an air bag 25 is installed in a seat back 12. When a side collision occurs against a vehicle, the air bag 25 is inflated between a passenger and an inner wall of a vehicle compartment. The air bag 25 has a separator 27 for vertically separating the inside of the air bag 25 into first and second chambers 28 and 29. The separator 27 is extended along a vehicle front-to-rear direction, and defines a communication portion 27a at a vehicle rear side in the air bag 25 for interconnecting the two chambers 28 and 29 and guiding gas blown by the inflator 22 from the first chamber 28 to the second chamber 29.

According to one embodiment, a servo area of a magnetic recording medium includes magnetic dots arrayed at a period L0. The magnetic dots include a plurality of magnetic dot regions divided in the cross track direction. A width Wm in the down track direction of the mth magnetic dot region from the innermost circumference and a number Nm of dot rows in the down track direction of the mth region meet a relationship represented by L0{Nm√3/2−0.3}≦Wm≦L0{Nm√3/2+0.3} (1)
Abstract:
According to one embodiment, a pit having a shape wherein the shapes of the top of a recording mark (recording start position) and the end of the recording mark (recording end position) are symmetrical can be formed on a stamper master with high reproducibility. As a result, the noise level/jitter degree of the reproduction signal obtained by reproduction from an optical disc as a final product can be reduced, thereby manufacturing at low cost the optical disc from which a signal can be stably reproduced.

Abstract:
The present invention provides an optical disk apparatus in which a first, second, third, and fourth optical disks are selectively installed, the first and second optical disks having different recording film characteristics and both having a single-layer recording layer, the third and fourth optical disks having different recording film characteristics and both having a double-layer recording layer. A control section determines which of the first to fourth optical disks has been installed, on the basis of the level of a reproduction signal from an optical head. Recording media serving as the optical disks are formed so that the light reflectances of a single-layer L-H medium in an initialized state, an L0 layer of a double-layer H-L medium in the initialized state, and an L0 layer of a double-layer L-H medium in an uninitialized state do not overlap the light reflectance of a single-layer H-L medium in the initialized state.
Abstract:
An air bag system for a motor vehicle is provided in which an air bag module is disposed inside a lid provided at a certain location within a vehicle compartment, such that the air bag module stores an inflator operable to generate high-pressure gas and an air bag in a folded state within a reaction can. The air bag system further includes a retainer that is selectively placed in a position to engage with a side portion of the air bag and a position to release the air bag, and a control device that places the retainer in one of the engaging position and releasing position. When the retainer is placed in the position to engage with the side portion of the air bag, the air bag deploys to a smaller size as compared with the size of the air bag deployed when the retainer is placed in the position to release the air bag.
Abstract:
This invention relates to an impact energy absorbing structure for a cabin of an automotive vehicle. The impact energy absorbing structure is provided with a trim member (10) covering an inboard side of a structural member, which constitutes the cabin of the automotive vehicle. An impact absorbing member is interposed between the inboard side of the structural member and the trim member (10), so that impact energy directed from a surface of the trim member (10) toward the structural member can be absorbed. When an occupant of the cabin is about to hit the structural member, impact energy is damped so that the occupant can be protected. The structural member includes a pillar (1) or the like, which constitutes the cabin of the automotive vehicle. The trim member (10) is arranged to cover an inboard side of the pillar (1) or the like. Resin-made ribs (11) or the like can be mentioned as the impact absorbing member. It is possible to design the structure so that impact energy directed from the surface of the trim member (10) toward the pillar (1) or the like can be absorbed through deformation or destruction of these resin-made ribs (11).
