摘要:
A semiconductor switching device includes a row of a plurality of switching elements connected in series. The input terminal of the input-nearest switching element and the output terminal of the output-nearest switching element are connected with the input terminal and output terminal of the semiconductor switching device, respectively. A control signal is applied to the control terminal of the output-nearest switching element. The semiconductor switching device comprises a first plurality of capacitive elements each of which is connected between the output terminal of the output-nearer switching element and the control terminal of the input-nearer switching element of the adjacent switching elements among the switching element row; and a second capacitive element connected between the output terminal and input terminal of the input-nearest switching element. At least the switching elements (S.sub.2 -S.sub.n) have insulating gates, respectively.

Embodiments in accordance with the present invention provide a magnetic head in which broadening of the write-field distribution in the track-width direction can be decreased without reducing the write-field intensity. A main pole includes a pole tip having a part which provides the write track-width and a yoke part recessed from the air bearing surface in the element height direction, the pole tip including at least two magnetic films having different track-width directions, and the throat height at the trailing side being made smaller than the throat height at the leading side.

The invention provides a color-developing composition without using a pigment or dye and capable of being colored sustainably and stably after mixing two liquid phases which are colorless before mixing. The composition consists of two discrete liquid phases, wherein the refractive index of each liquid phase is identical to each other at a point within the wavelength range from 400 nm to 800 nm, wherein a continuous layer and a dispersion layer are formed by mixing and dispersing said two phases whereby developing a color. Alternatively, the composition is a powder dispersion consisting of a liquid phase and a silica powder-containing solid phase, wherein said liquid phase has a refractive index n1 and said silica has a refractive index n2, which satisfy Equation (1): |n1−n2|

A method of fabricating a thin film magnetic recording head including a perpendicular recording head having an auxiliary pole, a main pole and a shield against an external magnetic field. The shield against the external magnetic field is formed so that an edge of the shield against the external magnetic field is disposed at a position recessed at least from an edge of the main pole relative to a surface against a medium.

A printer, which enables complicated printhead controls without a complicated logic circuit, includes a data table showing a control pattern of six controls stored in a RAM. When a drive trigger is inputted into a read-trigger generator, an address generator generates the address of the data table in the RAM as an address signal and inputs the address signal into the RAM. On the other hand, the read-trigger generator inputs a data-read trigger into the RAM. Control signals read by these signals are inputted into a head driver with heat pulses, which drives the printhead.
摘要:
A recording medium according to the present invention includes: a recording-medium supply mechanism; a single-sheet supply mechanism for supplying a recording medium S one sheet by another from a hold device to a conveyance path; and an overlap supply mechanism for supplying a desired number of sheets of a recording medium from the hold device in an overlapped state to the conveyance path. If there is one sheet or more of consecutive blank pages included in a recording medium to be supplied to the conveyance path, the recording apparatus overlaps and supplies a recording medium as many sheets as a value obtained by adding one to a number of the blank pages, to record recording data of a page immediately preceding or following the blank page.
