摘要:
An encoding apparatus which forms sector units of data, to each of which a header and an error detection code are added, from record data to be recorded on an optical disk, arranges a plurality of the sector units of data to form a matrix that is a block unit of data, scrambles the block unit of data exclusive of the headers and error detection codes, appends a first error correction code for each row of the block unit of data, and appends a second error correction code for each column of the block unit of data. The encoding apparatus comprises a generator of the error detection codes; a section that performs the scrambling; a generator of the first error correction codes; a generator of the second error correction codes; and an encoding controller that controls the processes in the above sections to be performed in parallel.
摘要:
A working vehicle with power steering, having a substantially closed accommodating space defined by an engine hood and a control panel, an engine disposed in the accommodating space and a steering shaft disposed in the control panel. A cooling fan produces cooling air flows moving toward the engine from an air intake formed in the control panel. A power steering apparatus for supplying steering assist power to the steering shaft, and a control unit for controlling the power steering apparatus, are arranged in the accommodating space to be exposed to the cooling air flows.

In a borosilicate glass plate containing Li.sub.2 O, Na.sub.2 O and K.sub.2 O and for use as a window plate in an alumina package for containing a semiconductor device, Li.sup.+ and Na.sup.+ ions are partially ion-exchanged by K.sup.+ ions in a surface of the glass plate to form a surface layer having a compressive stress of 200 Kg.f/cm.sup.2 or more, in order to make a thin window glass plate for the package having a thickness of 0.7 mm or less and a sufficient mechanical strength. The glass also has a thermal expansion coefficient of 50-75.times.10.sup.-7 /.degree. C. over a temperature range of 30.degree.-380.degree. C. so as to be thermally compatible with the alumina package. The glass consists essentially of SiO.sub.2 55-64%, Al.sub.2 O.sub.3 7-20%, B.sub.2 O.sub.3 11-19%, Li.sub.2 O 0-8%, Na.sub.2 O 7-20%, K.sub.2 O 0-4%, and RO 0.5-7% on the base of weight percent, where R is at least one of Mg, Ca, Sr, and Ba. In order to insure the ion exchange, amounts of Li.sub.2 O, Na.sub.2 O and K.sub.2 O are adjusted so that (Li.sub.2 O+Na.sub.2 O/(Li.sub.2 O+Na.sub.2 O+K.sub.2 O) is 0.7 or more.
