Title: Addition and transfer of functional material to base
Inventor: OGINO YASUHIRO
IPC: B41M5/40
Filed: 1991-09-12
Abstract: PURPOSE:To add and transfer a functional material to a base efficiently by allowing a sublimable or evaporable functional material to come in contact with a base, then laminating an impermeable cover for functional material on the opposite surface to the contact surface of the base and causing the base to capture the functional material after sublimation or evaporation. CONSTITUTION:A sulimable or evaporable functional material is allowed to come in contact with a base, then an impermealble cover for functional material is laminated on the opposite surface to the contact surface of the base, and the base is caused to capture the functional material by sublimating or evaporating the latter. In addition, an original image drawn or coated using a dyeing agent of sublimable or evaporable functional material is allowed to come in contact with the base for dyeing, then a cover which does not allow permeation of a dyeing agent is laminated on the opposite surface to the surface where the base comes in contact with the original image, and the original image is transferred to the base for dyeing by heating the original image and thereby sublimating or evaporating the dyeing agent. Thus it is possible to prevent the thermally sublimated or evaporated functional material from permeating through the base, and subsequently realize the efficient trapping of the sublimable or evaporable functional material in the base to enable the addition of a desired amount of the material to the base.

Title: Adaptive waveform equalizer
Inventor: HORI MASATOMO
IPC: H04B3/04
Filed: 1989-09-08
Abstract: PURPOSE:To realize an adaptive waveform equalizer with high stability and simple circuit constitution by obtaining amplitude information from a tap coefficient so as to control an input amplitude or an A/D converter. CONSTITUTION:When the amplitude of an output signal of a voltage controlled amplifier 6 is smaller than a prescribed amplitude, a control voltage of the voltage controlled amplifier 6 is increased and the amplification factor is increased. Conversely, when the amplitude of the output signal of the voltage controlled amplifier 6 is larger than a prescribed amplitude, the amplification factor is decreased. In this way, an input signal is amplified or attenuated so that the output of the voltage controlled amplifier 6 is equal to the prescribed amplitude, sampled and quantized by an A/D converter 5, equalized by a transversal filter 3 and the result is outputted from an output terminal 2. Moreover, a tap coefficient stored in a coefficient storage means 9 is selected to a value so that the quantization error in the A/D converter 5 is small and no overflow is caused in the transversal filter 3. Thus, stable and sufficient waveform equalization is attained without the need of a level detection means.

IPC: H03L7/107
Filed: 1993-09-20
Abstract: PURPOSE:To obtain the filter with a short lock time and less noise generated at time constant switching by gradually increasing a resistance with a time constant switching end signal. CONSTITUTION:A drain and a source of a FET 12 are respectively connected with both terminals of resistors 4, 5 whose resistance is high in a lag lead filter 3.

Filed: 1996-09-04
Abstract: PROBLEM TO BE SOLVED: To measure the peripheral and radial two-dimensional warpage of a disk via a single one-way position transducer element by calculating a disk warpage amount on the basis of the radial warpage angle of the disk. SOLUTION: Spots irradiated to the surface of a disk A from an irradiation means B are relatively moved in a radial direction on the light reflection surface of the disk A by means of a parallel displacement means E, with the disk A kept rotating with a rotary means F. Signals for the positional change of reflected light due to the radial warpage of the disk A, and signals for rotating positions from a rotation position read means G are composed by use of a signal composing means H. The signals so composed are stored in a signal recording means I, and the stored signals are computed by an arithmetic processing means J, thereby measuring the warpage of the disk A. According to this construction, only one unidirectional position transducer element is used to find a peripheral warpage angle from information regarding the radial warpage.  As a result, warpage angles in two directions can be concurrently measured in a single operation.
