Title: Magnetic recording and reproducing device
Inventor: NARITA TAKAHITO
IPC: G11B27/36
Filed: 1986-04-09
Abstract: PURPOSE:To easily confirm the recording state of a color difference signal by supplying switchingly a reproduced luminance signal and a recovered color difference subjected to synchronizing shaping to a black/white picture monitor switchingly. CONSTITUTION:A synchronizing shaping circuit 46 extends the pulse width of a recovered multiplex color difference signal formed by a multiplex chrominance signal reproducing system 40 and uses the pulse VD of the proper timing from a drum system control circuit 4 to form a pseudo verical drive signal. The multiplex color difference signal subjected to synchronizing shaping is fed to the black/white picture monitor 3 via switches 7,2 in place of the recovered luminance signal from a luminance signal reproducing system 30. Thus, the black/white reproduced picture by the multiplex color difference signal is displayed on the screen of the monitor 3. Thus, the recording state of the multiplex color difference signal is easily confirmed.

Inventor: MORI YOSHIYUKI
IPC: C30B31/06
Filed: 1991-03-20
Abstract: PURPOSE:To reduce the dispersion in the sheet resistance on the surfaces of silicon wafers for restraining the development of lattice defect by bettering the H2 implanting conditions of H2 in a diffusing pipe. CONSTITUTION:Multiple semiconductor wafers 8 and pyrolytic boron nitride (PBN) 6 as boron diffusion source are provided in a quartz tube 2. Next, H2 is implanted in the quartz tube 2 kept in an inert gas atmosphere and a high temperature state so as to diffuse the boron in the semiconductor wafers 8. At this time, H2 in the quartz tube 2 is to be within extremely low initial concentration range of 0.05% at maximum. Thus, HBO2 is formed by the reaction of an oxide to hydrogen on the surface of PBN wafers due to the led-in hydrogen so as to diffuse the boron on the semiconductor wafers 8 by the HBO2. Furthermore, the concentration of the HBO2 produced by H2 is lowered high concentration layer deposited on the semiconductor wafers 8. Accordingly, the development of lattice defect in the semiconductor wafers 8 can be restrained.

Title: Switching device
Inventor: KIKUYAMA SEIICHIROU
IPC: H03K17/615
Filed: 1980-06-16
Abstract: PURPOSE:To perform quick discharge and charge in a switching device even when charge accumulated in a capacitor is large. CONSTITUTION:As a potential is applied to an input terminal 4, a capacitor 2 is charged via a diode 9. Then, when the potential to the input terminal 4 drops by as low as a voltage twice the base-emitter voltage (VBE) of a transistor below the potential of the capacitor 2, a TR5 turns on to flow a base current from a TR6, which then conducts. The TR6 supplies a current, obtained by increasing the base current flowed by the TR5 by current-amplification-factor times, to the base of a TR7. On the other hand, the TR7 supplies a current, obtained by increasing the base current by current-amplification factor times, to the base of a TR8. The TR8 permits a current, obtained by increasing the base current by current-amplification- factor times, to flow out of the capacitor 2. Thus, quick discharge is carried out.

Title: Production of liquid crystal element
Inventor: NAKAMURA KOJI
IPC: G02F1/1341
Filed: 1990-03-29
Abstract: PURPOSE:To obviate the generation of a linear defect arising from the shrinkage of the volume of a liquid crystal in the display part of the liquid crystal element by slowly cooling the element while applying a local temp. gradient thereto and completing the phase transition of the liquid crystal by continuously moving the boundary of a smectic phase region. CONSTITUTION:A liquid crystal material 4 is heated to the temp., at which a phase exclusive of the smectic phase is exhibited. After this material is packed between a pair of substrates 2 and 3, the element 1 packed with this liquid crystal material 4 is slowly cooled while the prescribed local temp. gradient is applied to the element. The element is slowly cooled until the temps. of all the places of the element finally attain the transition temp. at which the semctic phase is attained or below. Namely, the element is slowly cooled while the position where the transition temp. is attained is moved by each place and, therefore, the boundary position where the phase transition of the liquid crystal material 4 packed into the element 1 arises is continuously moved according to the local temp. gradient. Since the liquid crystal part where the phase exclusive of the smectic phase is exhibited is high in flowability, the influence of a volume decrease is concentrated to the place having no relation the liquid crystal display. The liquid crystal element 1 which obviates the generation of the liner defect occurring in the shrinkage of the liquid crystal material is obtd. in this way.

Title: Ink-jet print apparatus

Filed: 1996-04-04
Abstract: PROBLEM TO BE SOLVED: To decrease generation of stripe fluctuation in an image by making the diameter of the formed ink dot invariant regardless of inks used when a plurality of inks with different concn. are used for performing gradation print. SOLUTION: The amt. of jetting of each ink is made different by changing respectively the width of a driving pulse applied on an electricity-heat convertor for each head for jetting each ink with a different concn. and thereby, a dot with a fixed diameter of √2x+α to a picture element with an area of x×x is formed by the jetted ink at any time when the ink is jetted from any head. As the result, the formed dot always covers the hole picture element to prevent a gap between the dots from being generated in an image and to accordingly suppress generation of stripe fluctuation caused by this gap.
