The operation member includes a plurality of key regions and is configured to be deformable. The electrode substrate includes a first capacitive element arranged opposed to each of the plurality of key regions and a second capacitive element arranged around the first capacitive element. The electrode substrate is capable of electrostatically detecting a change of a distance from each of the plurality of key regions. The first support includes a plurality of first structures and a first space. The plurality of first structures connect between the electrode substrate and the operation member. The first space is formed between the plurality of first structures and capable of changing the distance between each of the plurality of key regions and the electrode substrate according to an input operation.

Deformable input apparatus and electronic apparatus including key regions

There is provided an information processing device including a capacitance variation detection unit configured to detect an operation input to each of a plurality of key regions as a capacitance variation amount of a capacitive element, the key region being provided on a sheet-like operation member, the capacitive element being provided in association with each of the key regions, the capacitance variation amount being dependent on a change in a distance between the key region and the capacitive element, and an input state determination unit configured to determine whether an input state of the key region is an ON state based on the detected capacitance variation amount, the ON state being a state in which the operation input to the key region is decided to be valid. The input state determination unit determines an end of the ON state based on a differential value of the capacitance variation amount.

Method and apparatus for controlling an input device

An input apparatus including a deformable sheet-like operational member having a plurality of key areas.

Deformable keyboard with adjustable layout

A sensor unit is provided and includes a first substrate, first and second electrodes, an input portion disposed so that a gap exists between the substrate and the input portion, a plurality of first structures disposed in the gap and extending at least partially between the first substrate and the input portion, and a second insulating structure disposed on a side of the first structures that is away from the input portion, or between adjacent first structures. The sensor unit is configured to detect a change in capacitance between the first and second electrodes upon a change in position of the input portion relative to the first substrate.

In a magnetic recording and reproducing device having ahead and ahead, an azimuth recording operation is carried out on an obliquely evaporated magnetic tape. Angles &#x3b8;and &#x3b8;formed by a direction of a head azimuth of thehead and thehead and a longitudinal direction of the magnetic tape are respectively set to angles at which an output difference between a reproducing signal of a track recorded by thehead and a reproducing signal of a track recorded by thehead is located within three decibels. Thus, an output difference between the two magnetic heads is reduced while the loss of electromagnetic conversion is reduced.

A polypropylene resin composition is herein disclosed which is obtainable by blending (A) 100 parts by weight of a polypropylene resin comprising (a) 100 to 20% by weight of a homopolymer of propylene and/or a propylene copolymer containing 4% by weight or less of another olefin unit in which in a pentad fraction by .sup.13 C-NMR, [rrrr/(1-mmmm)].times.100 is in the range of 20 to 60%, a Tm measured by a DSC is 150.degree. C. or more, and a melt enthalpy is 100 J/g or less, and (b) 0 to 80% by weight of a propylene copolymer containing 10 to 80% by weight of an olefin unit other than propylene, with (B.) 0.01 to 5 parts by weight of an octyltin salt of a fatty acid, an alkylenebisfatty acid amide, a fatty acid ester of a polyvalent alcohol, or a metal salt of an aliphatic monocarboxylic acid. The employment of this polypropylene resin composition permits, under a good moldability by the calender molding machine, the manufacture of films and sheets having less thickness unevenness, excellent appearance and heat resistance and such flexibility as in molded articles of a plastic polyvinyl chloride.

Polypropylene resin composition

A recording and playback device utilizing magnetic tape, such as a tape cassette, as a recording medium includes a magnetic head arranged to contact one side of the magnetic tape and a stabilizer arranged positioned directly opposed the magnetic head corresponding to the opposite side of the magnetic tape such that the magnetic tape move along a path interposed between the stabilizer and the magnetic head. The stabilizer includes a tape slider surface in contact with the side of the tape opposite the magnetic head contacting side. Further, the tape slider surface of the stabilizer may be formed with a recessed portion and tape surface scraper portions. According to this structure vibration of the magnetic tape in the vicinity of the magnetic head is greatly reduced such that a head servo for control of the magnetic head may accurately position the magnetic head even in devices utilizing a very small track pitch. Also read/write error, tape dropout, and the like, due to foreign matter entering the tape path, is reliably prevented. Further, space between the magnetic tape and the head is reduced and contact pressure between the head and the tape is maintained to optimize recording and or playback operations between the head and the magnetic tape.
