摘要:
Multibeam optical disk record and reproduction apparatus and method, in which at least two light beams generated are concentrated in different positions of on recording tracks of a recording medium to record or reproduce data to or from the recording medium on the different positions at the same time. The light beams are moved independently of each other across the recording tracks so that any one light beam is movable during the recording or reproducing of data by another light beam. This allows parallel recording/reproducing with a plurality of light beams without producing areas unaccessed due to the jumps of the light beams.

A disk drive is mounted to a circuit board by directly connecting a disk drive apparatus with a circuit board by using a DIP, PLCC, QFP, or PGA mounting method. The disk drive apparatus has an interface for controlling a disk drive in response to a control signal, a data bus signal and an address bus signal outputted from an information processing unit so that the disk drive apparatus may be connected like a memory card of the information processing unit.

The inflator assembly comprises a cylindrical housing main body which is made by extrusion so that it is possible to achieve a desired cross section which optimizes the progress of combustion of the propellant while minimizing the size of the housing. In particular, by using a member clad or mounted with brazing material for an internal component of the assembly, such as the ignition pipe, a leg section for supporting the ignition pipe inside the housing, a wall section for defining a separate combustion chamber, at least one of the end plates for closing the axial ends of the housing main body, and a perforated plate member serving as the perforated section, it is possible to simplify the manufacturing process, and thereby reduce the manufacturing cost.

A plurality of commands which may be sent sequentially from a host computer are interpreted by a host command interpreter to generate a disk command for each disk unit. When these commands make up an access demand for a single continuous area, they are grouped into a single command, which is executed substantially at the same time at each disk unit. Also, a plurality of RMW processing systems having different command issued to disk units are available. A selection condition is detected from the I/O demand information supplied by a host computer, and an optimum one of a plurality of RMW processing systems is selected and executed on the basis of the selection condition.

A host computer is connected with a magnetic disk storage device by an SCSI bus. In the magnetic disk storage device, a plurality of partitions are set in a disk drive unit and have device identifiers (ID's) respectively allocated thereto as SCSI ID's=1, 2 and 3, which are supported by a disk controller. When the host computer has acquired the control of the SCSI bus through arbitration and has selected, for example, the partition with the device identifier SCSI ID=1, the disk controller permits the host computer to access the partition in response to the selection. Since the partitions are different in attributes, properties etc., they appear as magnetic disk storage devices that are separate from one another when viewed from the host computer. Thus, the single magnetic disk storage device can be managed as a plurality of storage devices of different nature.

摘要:
Each of air bag devices includes an inflator mounted in a seat back, a first air bag which is connected to the inflator and developed into a space between an occupant and a side door, and a second air bag connected to the first air bag and developed into a space between the occupant and an instrument panel. When the internal pressure in the first air bag exceeds a predetermined value, the internal spaces in the first and second air bags are put into communication with each other through a pressure valve. When a vehicle collides with another vehicle or an obstacle, the first air bag is first inflated and developed by a high pressure gas generated by the inflator. When the first air bag has been developed, the pressure valve V is opened, causing the second air bag to be developed. Thus, not only upon a frontal collision and a side collision of the vehicle, but also upon an oblique collision of the vehicle, it is possible to reliably hold the occupant.

A positive type radiation-sensitive resin composition which comprises a 1,2-quinonediazide compound and an alkali-soluble novolac resin produced by poly-condensing phenols represented by the formulas (I) and (II) in a molar ratio of (I)/(II) of 1/99 to 100/0 with a carbonyl compound: ##STR1## wherein R.sup.1 and R.sup.2, which may be the same or different, represent hydroxyl groups, hydrogen atoms, alkyl groups, aryl groups, aralkyl groups, alkenyl groups, halogen atoms, alkoxy groups, alkoxycarbonyl groups, aroxycarbonyl groups, alkanoyloxy groups, aroyloxy groups, acyl groups, cyano groups or nitro groups, ##STR2## wherein R.sup.3, R.sup.4 and R.sup.5, which may be the same or different, represent hydrogen atoms, alkyl groups, aryl groups, aralkyl groups, alkenyl groups, halogen atoms, alkoxy groups, alkoxycarbonyl groups, aroxycarbonyl groups, alkanoyloxy groups, aroyloxy groups, acyl groups, cyano groups or nitro groups. The above positive type radiation-sensitive resin composition is excellent in dry-etching resistance, resolution and heat resistance, and appropriate as a positive type resist for producing integrated circuits in which a resist pattern is formed, and also as a positive type resist for producing a mask.

In an air bag unit for use in a motor vehicle, including a casing mounted onto a steering wheel assembly, a gas generator arranged in the casing, an inflatable air bag fixed to the casing and communicating with the gas generator and a cover adapted to cover the casing, the cover comprises a base portion fixedly mounted to the casing and a top portion connected to the base portion and having first and second weakened portions, the first and second weakened portions being broken upon inflation of the air bag, so that the top portion is divided into two cover pieces and that these cover pieces are open outwardly, a reinforcing member embedded in the cover except the first and second weakened portions, and one or a plurality of hooks arranged in the base portion, each hook being engaged with the reinforcing member and being fixed to the casing of the air bag unit. Each hook includes a base plate and a bent portion. The base plate is fixed to the casing, and the bent portion has a plurality of hook elements with which the reinforcing member is engaged.
